The Skin picker now groups Light and Dark options, and each light skin ships a matching xterm ANSI palette plus `color-scheme: light` so native selects, date pickers and scrollbars stop rendering as dark OS widgets on a light page. Terminals set `minimumContrastRatio: 4.5` under a light skin (main terminal and teammate terminals both), which keeps CLI output that assumes a dark background readable, and `applyTerminalSkin()` now refreshes the zero-lag input overlay so typed-but-unflushed text does not keep the previous theme's colors. + + Elevated surfaces (modals, command palette, dropdowns, subagent and ultracode windows, file preview, attachment tray, mobile sheets) now resolve through shared `--floating-bg` / `--control-*` / `--banner-bg-*` / `--modal-backdrop` / `--elevated-shadow` tokens instead of hardcoded near-black rgba, so they follow whichever skin is active. On the Daylight skins this lifts modals slightly off the page background; OG Codeman pins its own near-black value to keep that palette neutral. + + Also defines twelve CSS compatibility aliases (`--bg-primary`, `--bg-secondary`, `--bg-tertiary`, `--text-primary`, `--text-secondary`, `--border-color`, `--accent-color`, `--success`, `--error`, `--danger`, `--font-mono`, `--shadow-lg`) that panels and overlays already referenced in about 79 places but which were never actually declared, so those rules silently resolved to nothing. Status badges and accent-tinted pills (search filter chips and result badges, session tab mode pills, respawn state, Ralph priority and circuit-breaker badges, tunnel and voice status, mobile case picker) no longer keep their pale light-on-dark ink under a light skin, where it measured 1.0 to 1.9:1 and made the search filter chips invisible. + + New static regression `test/skin-themes.test.ts` guards the four-way parity between the CSS token block, the xterm palette, the pre-paint allowlist and the Settings picker. + +## 1.8.2 + +### Patch Changes + +- Web tabs: open dashboard URLs as tabs beside agent sessions, plus terminal link fixes. + + **Web tabs.** The Run dropdown gains a "Web / URL" section. A saved URL renders as a tab in the same strip as Claude/Codex/Gemini sessions, with the same Alt+1-9 numbering, an icon picker, and per-device tab order. Frames stay mounted while hidden (LRU-bounded), so switching tabs never reloads a dashboard. + + Dashboards are proxied through Codeman's own origin, because a direct iframe fails three ways at once: an HTTPS Codeman cannot embed a plain-HTTP target (mixed content, with no override at all on iOS Safari), many dashboards send `X-Frame-Options: DENY`, and Codeman's own `default-src 'self'` CSP blocks cross-origin frames. Proxying dissolves all three and leaves the production CSP unchanged. The fetch happens server-side, so a tailnet-only or localhost-only dashboard is reachable from any device that can reach Codeman. + + The proxy is not an API surface: it authenticates on a 192-bit capability in the path (memory-only, rolling TTL, bound to the minting user, revoked on edit or delete) and is exempt from the cookie and Origin checks, because a sandboxed iframe is opaque-origin and sends neither. The Host allowlist is never bypassed. Iframes omit `allow-same-origin` unless a URL is explicitly marked trusted, and `Authorization` plus the session cookie are stripped upstream in both modes so `CODEMAN_PASSWORD` cannot leak into a dashboard. Includes an HTTP and WebSocket proxy, redirect/cookie/`` rewriting, a runtime URL shim for requests built by dashboard JavaScript, and CORS handling for the opaque-origin frame.

A WordPress edit link resolved to `?post=1479` and Claude Code's own `/login` URL was unusable. `&` is now part of a URL while `&&` remains a boundary. + - Links wider than the terminal were cut at the row boundary. The link provider now stitches continuation rows into one logical line and maps offsets back across rows. Handles both soft wraps (emulator, `isWrapped`) and hard wraps (a program wrapping its own output and emitting a newline, as Ink does), the latter being why the `/login` URL grew longer as the window was widened. + - Image and PDF paths were not matched at all, so pasted-screenshot paths rendered as plain text. They now link and open the file preview, which renders images inline. + + **Also fixes** a pre-existing bug where `.toolbar`'s `backdrop-filter` created a stacking context that trapped the Run menu's z-index, letting the welcome overlay cover it: with no session open, every item in that menu (Claude Code included) was unclickable. + +## 1.8.1 + +### Patch Changes + +- Mobile toolbar: a dedicated Enter button, and Shell moves into the Run dropdown. + + Submitting is a constant need on a touch keyboard, so on phones (≤430px) the toolbar slot that held "Shell" now holds a dark blue **Enter** button. Starting a shell, the far rarer action, moves into the expandable Run dropdown as `Terminal / Shell` (the Run button then reads "Run SH"). Desktop and tablet are unchanged: the green Run Shell button stays exactly where it was. + + Enter is replayed through the terminal's own input path rather than posted to the input API. This matters because local echo is on by default on touch devices: the characters you type are buffered client-side and have not yet reached the PTY, so sending a bare carriage return would submit an empty line and leave your text stranded on screen. Replaying the keypress flushes the buffered text first, then submits. + + Installer: re-runs and updates now preserve the existing network binding instead of silently reverting it, so upgrading no longer changes how the dashboard is reachable. + + Default desktop header is cleaner: the file viewer is shown by default and the plan-usage chip is unchanged, while the token-count chip and lifecycle-log button now default off. Stored preferences are still honored. + + Docs and repo housekeeping: fresh phone screenshots and a new hero GIF in both READMEs, contributor and total-commit badges, and a much shorter repo root. `SECURITY.md` moved to `.github/` (GitHub resolves it there, so the Security policy tab is unaffected), `SPEEDRUN.md` to `docs/`, the knip config to `config/`, and Prettier's config into the `"prettier"` key of `package.json`. `CLAUDE.md` was split so the always-loaded guidance is roughly half its former size, with the deep implementation detail preserved verbatim in `docs/architecture-invariants.md`. + ## 1.8.0 ### Minor Changes diff --git a/CLAUDE.md b/CLAUDE.md index 71d68557..4c0c0d1d 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -2,6 +2,12 @@ This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. +> Deep implementation detail lives in [`docs/architecture-invariants.md`](docs/architecture-invariants.md).

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**.

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`.

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-.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). +- **Multi-CLI prefix discipline** — 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.

All three **require tmux with no direct PTY fallback**, because secrets are injected via socket-scoped `tmux setenv` and never on the spawn command line. ⚠️ `run*()` in `session-ui.js` MUST unwrap the `{success,data}` envelope; reading the raw shape silently breaks the run. → [architecture-invariants#external-cli-modes-opencode-codex-gemini](docs/architecture-invariants.md#external-cli-modes-opencode-codex-gemini) -**Remote SSH cases** (COD-94/#145): cases can point at a **remote host** (`~/.codeman/remote-hosts.json` + `remote-cases.json` via `src/remote-hosts.ts`; CRUD under `/api/cases` — cases route file). A remote session launches a LOCAL tmux pane running `ssh ` that creates a durable REMOTE tmux session on a **dedicated socket** `-L codeman-remote` with name `codeman-ssh-` — deliberately failing the remote Codeman's `SAFE_MUX_NAME_PATTERN` so a Codeman instance on the target host never adopts it; no `-g` global tmux options are set remotely. `remotePath`/`identityFile` are schema-guarded against shell injection (backticks/`$` rejected — same approach as `extraSshOptions`); remote tmux availability is probed via `checkRemoteTmuxAvailable()` in quick-start (ssh args carry `-o ConnectTimeout=10`). Remote claude defaults to `exec claude --dangerously-skip-permissions`; per-host `commands.*` override. Session kill best-effort kills the remote tmux too. `SessionState.remote`/`MuxSession.remote` round-trip through recovery (`restoreMuxSessions` passes `remote` back into the Session constructor). ⚠️ Run flows must route remote cases through `POST /api/quick-start` (which resolves the remote case and skips LOCAL CLI availability gates) — `POST /api/sessions` stat-validates `workingDir` locally and has no `caseName`. `envOverrides`/`effort`/`modelOverride`/`codexConfig`/`geminiConfig` are rejected for remote quick-starts (not silently dropped). UI: Create Case modal → Remote tab. Tests: `test/remote-hosts.test.ts`, `test/remote-ssh-options.test.ts`. +**Run launch synchronization**: the Run entrypoint holds an in-flight lock and disables `#runBtn` for the whole launch (≥500ms), so a double click cannot create duplicate sessions with the same `w-` name. `_ensureCreatedSessionVisible()` runs before `selectSession()`, and `_onSessionCreated()` stays an idempotent upsert, so POST-first and SSE-first ordering both produce exactly one rendered tab. → [architecture-invariants#run-launch-synchronization](docs/architecture-invariants.md#run-launch-synchronization) -**Docker cases** (shipped 1.4.0; user guide `docs/docker-cases.md`, design `docs/docker-cases-plan.md`): a case can point at a **container** instead of a local/remote path, and any of the five CLI backends runs INSIDE it. Like remote-SSH, it is a **LOCATION OVERLAY on cases, never a sixth `SessionMode`** (`SessionMode` is unchanged). Storage `~/.codeman/docker-hosts.json` + `docker-cases.json` via `src/docker-hosts.ts` (direct mirror of `remote-hosts.ts`: `readDockerHosts`/`readDockerCases`, `toSessionDocker`, `dockerDisplayPath`, and the PURE builders `buildDockerBaseArgs`/`buildDockerCreateArgs`/`containerApiUrl`/`hostGatewayAlias`/`dockerConfigHash`). CRUD `/api/docker-hosts` + `/api/cases/docker-link`, plus **one-click** `/api/cases/docker-quickcreate` (Create New "Run in Docker" checkbox → case folder in `CASES_DIR` + auto-provisioned shared `default` host + auto-start a session inside; an expandable Template picker Small/Medium/Large/GPU or any override creates a per-case `q-` host), and export/import (`/api/docker-cases/:name/export`, `/api/docker-cases/import`, `GET/DELETE /api/docker-exports`) — all in `case-routes.ts`. Run flows route through `POST /api/quick-start` like remote (session-routes.ts docker branch, skips LOCAL CLI-availability gates). **Launch model**: exactly one long-lived container **per case** (`codeman-case-`, PID1 `sleep infinity` under `--init`); a LOCAL tmux pane runs `docker exec -it` into a **durable in-container tmux** on dedicated socket `-L codeman-docker`, session `codeman-dkr-` (deliberately fails `SAFE_MUX_NAME_PATTERN` so a Codeman running INSIDE the container never adopts it, exactly like remote's `codeman-ssh-`). Builders `buildDockerLaunchCommand`/`buildDockerKillCommand` in `tmux-manager.ts` (image-check → `docker inspect||create` → start → exec, all idempotent). The container is **shared by all sessions of the case**: `buildDockerKillCommand` kills ONLY that session's in-container tmux session, NEVER `docker stop` while siblings remain; `docker rm -f` happens only on case-delete (plus an instance-scoped boot reaper keyed on the `codeman.instance` label). **Two-layer durability/resume** (the central design point): (1) Codeman-PROCESS restart with the container still up → `tmux new-session -A` reattaches the SAME live agent (paneCommand ignored); (2) container stop/reboot/OOM → inner tmux is gone, so the re-run pane command resumes the conversation from the bind-mounted transcript: claude mode pins a DETERMINISTIC conversation id via `claudeDockerPaneCommand()` (`tmux-manager.ts`) — fresh launch `claude --session-id || claude --resume ` (a duplicate `--session-id` exits 1 "already in use", so the fallback RESUMES after a container stop; verified CLI behavior), explicit resume `--resume || --session-id ` so a stale id never dead-panes (leading `exec ` is stripped — an exec'd first branch could never fall back); codex `resume ` / gemini `--resume` keep `appendResumeFlag`. The resume id rides `resumeSessionId` through create/respawn options and persists on `DockerCase.lastClaudeSessionId` via `persistDockerCaseClaudeSessionId()` (written at quick-start launch, and again on hook/last-response conversation-id adoption so post-`/clear` switches track; seeded back when `resumeOnStart`, default true); `-A` makes the pane command self-selecting (inert on reattach, active only when tmux was re-created). **Config drift** (`dockerConfigHash` → `codeman.confighash` label): quick-start compares via `checkDockerConfigDrift()` and REFUSES a drifted launch with `CONFLICT`; the UI confirm calls `POST /api/docker-cases/:name/recreate` (refused while case sessions are live) which `docker rm -f`s so the next launch recreates with the new config — host config edits actually take effect. **Workspace** is a REAL host dir bind-mounted at the SAME absolute path (mirror, `dst==src`), so `Session.workingDir = hostWorkspacePath` keeps file-routes/attachments/watchers on real host bytes AND the in-container transcript projHash matches the host so subagent/workflow correlation (and thus resume-id capture) works; `resolveMuxAttachCwd` returns `/tmp` for docker (the local pane only runs `docker exec`). **Creds** arrive commit-safe and ISOLATED (1.4.1; replaced the whole-dir RW mounts that let in-container CLIs write refreshed tokens/state back to the host): shared RW across the boundary is ONLY what host-side reads/resume need (`~/.claude/projects` transcripts; codex `sessions/` + `history.jsonl` for response-viewer/`codex resume`); everything else is SEEDED (RO mount, copied into container HOME once at launch via `[ -e ] || cp`; the container refreshes its own copy and never writes back): `~/.claude.json` is merged through `buildSeamlessClaudeConfig()` (forces `hasCompletedOnboarding` + theme + workspace trust, so no login wizard/theme picker/trust prompt inside the container), plus `.claude/{.credentials.json,settings.json,stats-cache.json}`, plus whole-dir seeds for `~/.gemini`/`~/.config/{gcloud,opencode}` (`resolveDockerClaudeArtifacts`/`resolveDockerCredentialArtifacts` in `docker-hosts.ts`). Bind mounts are physically excluded from `docker commit`, so exports stay secret-free; API-key CLIs get exec-time NAME-ONLY `--env OPENAI_API_KEY` (no `=value`); the SEALED profile is `mountCredentials:false` + `network:none`. NEVER a create-time `-e` for secrets, NEVER `--privileged`, NEVER the docker socket. **Hardening** on every create: `--cap-drop ALL`, `--security-opt no-new-privileges`, `--pids-limit`, `--memory`==`--memory-swap`, non-root via `--user :0` (Linux, GID 0 for writable HOME) / `--userns=keep-id` (podman rootless) / baked uid (Docker Desktop), `--pull=never`, `--init`. Base image `codeman/agent:base` is BUILT LOCALLY from `docker/agent.Dockerfile` (node22 + tmux + claude/codex/gemini/opencode, OpenShift arbitrary-uid HOME, `C.UTF-8` locale so tmux/Ink render real box-drawing glyphs; Codeman also sets `LANG`/`LC_ALL` at run time for containers built before that line) via `scripts/build-agent-image.mjs` OR **auto-built on first use** (1.4.1: `ensureAgentBaseImage()` in `docker-hosts.ts`; idempotent + concurrency-safe, only the DEFAULT image ref is ever auto-built, `--pull=never` stays absolute; build output streams over SSE `docker:imageBuildStarted`/`imageBuildProgress`/`imageBuildComplete`/`imageBuildFailed`, and quick-create returns `imageBuilding:true` while the first launch awaits the gate); tmux-in-image is a HARD gated prerequisite (`checkDockerTmuxAvailable`), never a silent bare-exec fallback. **Hooks + model**: the workspace-scaffolding block DOES run for docker (writes `.claude/settings.local.json` + the CLAUDE.md scaffold into the real host dir), so `modelOverride` works via `settings.local.json` — it is a `QuickStartSchema` field applied for local AND docker quick-starts (`updateCaseModel`), sent by the frontend docker run path (the one deliberate difference from remote, which rejects it); `effort`/`envOverrides`/`codexConfig`/`geminiConfig`/`openCodeConfig` stay rejected. In-container hook curls hit `containerApiUrl(process.env.CODEMAN_API_URL, engine)` (swaps ONLY the hostname to the gateway alias, preserving scheme+port so prod HTTPS still works); the host guard allowlists both `host.docker.internal`/`host.containers.internal` (`DOCKER_HOST_GATEWAY_ALIASES` in `network-auth-policy.ts`). ⚠️ On a **loopback-only** bind (the prod default) a container cannot reach 127.0.0.1, so in-container hooks fire ONLY when `CODEMAN_DOCKER_BRIDGE_HOOKS=1` — an opt-in SECOND listener on the docker bridge gateway (`_startDockerBridgeHooksListener` in `server.ts`; gateway auto-detected via `detectDockerBridgeGateway`, or set `CODEMAN_DOCKER_BRIDGE_HOST`) that serves ONLY the hook endpoints (403 for any other path) into the same secret-gated pipeline; otherwise idle detection falls back to output-based through the docker-exec PTY. Container-set `CLAUDE_CODE_TMPDIR` keeps claude launching regardless of workspace path. `SessionState.docker`/`MuxSession.docker` round-trip through recovery. Every docker IO path is `IS_TEST_MODE` (VITEST) no-op'd; the pure builders are unit-tested. **Export/import** (`src/docker-export.ts`): full-image (`docker commit` + `save | gzip` + workspace tar + manifest) or workspace-only → one portable `~/.codeman/docker-exports/-.codeman-container.tgz`; import validates per-member sha256, traversal-guards the workspace tar, `docker load`s + quarantine-retags the image (`codeman/imported-:`, never overwriting a local tag); a `saveImageToTar` stream `pipeline` avoids truncation. **GPU** passthrough (`gpus` → `--gpus`, needs the NVIDIA container toolkit) and **elastic disk** (no `--storage-opt` cap, so container storage grows with data). SSE `docker:exportComplete`/`exportFailed`/`importComplete` (both registries). **UI** in `session-ui.js`: Create Case **Docker** tab (collapsed/compact form since 1.4.1), the one-click checkbox + Template picker, short `(docker)` case-menu tags, and a Manage-tab Export button; docker AND remote sessions name their tabs `w-` via the shared `_nextCaseSessionStartNumber()` so all tabs follow one naming convention.

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).

Proxying leaves the prod CSP unchanged (`/webview/...` is `'self'`). ⚠️ The proxy is **NOT an API surface**: it authenticates on an in-memory capability in the path and is correspondingly exempt from the cookie + Origin checks; that exemption is fenced to safe methods and non-`/api` paths and is pinned by `test/webview-auth-exemption.test.ts`. ⚠️ Iframes omit `allow-same-origin` unless a dashboard is explicitly marked `trusted`, and `Authorization`/`codeman_session` are stripped upstream in **both** modes so `CODEMAN_PASSWORD` cannot leak. ⚠️ A sandboxed frame is **opaque-origin**, which breaks two things `curl` can never reproduce: its runtime-built root-absolute URLs escape `` (fixed by an injected `runtimeUrlShim()`), and its same-host `fetch`/XHR are CORS-checked with `Origin: null` (fixed by `buildProxyCorsHeaders()` plus exempting the proxy from the global `OPTIONS`-204 short-circuit in `registerSecurityHeaders`).

Shortcuts live in a rebindable registry (`DEFAULT_SHORTCUTS`/`getShortcutRegistry()`/`matchesShortcutEvent()` in app.js; overrides persist under `settings.shortcutOverrides` via `saveAppSettingsToStorage`); App Settings → Shortcuts renders capture/disable rows; `Ctrl+?` opens the registry-driven overlay (footer links to the full `#helpModal` reference). ⚠️ Palette-chord keys must ALSO be swallowed in `attachCustomKeyEventHandler` (terminal-ui.js) or xterm writes the control byte (0x0B) into the PTY. ⚠️ `saveAppSettings()` rebuilds settings from the DOM — keys edited elsewhere (`shortcutOverrides`, `showTokenCount`, `showCost`) need explicit `_prev` carry-over. + +### WebGL renderer toggle + +**WebGL renderer toggle** (#140, `webglRendererEnabled`): per-device (`displayKeys` set, stripped from the server payload — NOT in `SettingsUpdateSchema`, which is `.strict()`). The GPU-stall watchdog's sticky `codeman-webgl-disabled` marker survives page loads; it's cleared only by an explicit OFF→ON save transition or `?webgl=force` (`shouldSkipWebGL` in constants.js). `?nowebgl` still forces the DOM renderer per-load. + +### Header button visibility (multi-monitor, response viewer, file viewer, cron) + +**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`). Works for Claude AND Codex sessions (#152): Codex last-responses are located via a 4-layer rollout resolution under `CODEX_HOME` (history pin → originator match → resume-UUID → cwd fallback with other-pane exclusion), with injected-context filtering and event/legacy dedup — tests in `test/routes/session-routes-codex-last-response.test.ts`. 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. +**File Viewer button** (header, 1.4.1) is **shown by default on desktop** since `211f3c0` (post-1.8.0): toggle under App Settings → Display → **Header Displays** → File Viewer (`showFileViewerButton`, in the per-device `displayKeys` set, fallback default `true`). Purely client-side like the response viewer: the template now ships the button VISIBLE (no `--hidden` class) and `applyHeaderVisibilitySettings()` toggles the `btn-file-viewer--hidden` marker class after settings load; phones still hide it via mobile.css. The button toggles the file-browser panel open/closed without opening the settings modal (`panels-ui.js`). The same commit set the **default desktop header** to WS/CPU/MEM + File Viewer + gear: the token-count chip (`showTokenCount`, no settings-UI toggle) and the lifecycle-log button (`showLifecycleLog`) both default **OFF** now (templates ship them hidden; stored prefs still honored). The plan-usage chip default is unchanged (opt-in, see Plan-usage chip). The **Cron toolbar button** joined the same opt-in pattern in 1.6.0: template ships `btn-cron--hidden`, `applyHeaderVisibilitySettings()` toggles it via the per-device `showCronButton` setting (default OFF, App Settings → Display → Header Displays); cron jobs themselves are unaffected. + +### Gesture control: the setting + +**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: the source package + +**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 + +**Theme skins** (App Settings → Display): the `skin` setting selects a palette via a `data-skin` attribute on ``. Dark values: `daylight-blue` (default), `daylight-green`, `og` (OG Codeman). Light values: `paper-gray`, `solarized-light`, `catppuccin-latte`, `rose-pine-dawn`. CSS lives under `[data-skin="…"]` blocks in `styles.css`. To avoid a flash-of-wrong-theme, an **inline pre-paint script** in `index.html` (``) reads `localStorage['codeman:skin']` and sets `data-skin` before first paint; `settings-ui.js` `applySkin()` applies it live on save (sets `html[data-skin]` + `window.__codemanSkin`, syncs the standalone `codeman:skin` key with the settings blob, updates the `` from the resolved `--bg-dark`, and calls terminal-ui.js `applyTerminalSkin()` to re-theme live terminals). `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. + +**Adding a skin means touching four places, and each one fails silently on its own**: (1) the `html[data-skin="…"]` token block in `styles.css`; (2) the xterm ANSI palette in `CODEMAN_XTERM_THEMES` (terminal-ui.js) — a missing entry falls back to `daylight-blue`, so the terminal simply stays the wrong color; (3) the pre-paint allowlist array in `index.html` — a skin missing there is coerced to `daylight-blue` on every reload, which reads as "my theme keeps resetting"; (4) the `` popups, date pickers and scrollbars as dark widgets on a light page. xterm `minimumContrastRatio: 4.5` (set at construction in terminal-ui.js **and** panels-ui.js for teammate terminals, and re-applied in `applyTerminalSkin()`), because CLIs emit colors chosen for dark backgrounds; dark skins keep `1` to avoid the per-cell contrast work. And `applyTerminalSkin()` must call `this._localEchoOverlay?.refreshFont()` — the zero-lag overlay **caches** the terminal fg/bg at construction, so without the refresh typed-but-not-yet-flushed text keeps the previous theme's dark backing after a live skin switch. + +**Shared surface tokens, not literals.** Elevated/floating surfaces resolve through `--floating-bg`, `--control-bg{,-hover}`, `--control-border{,-hover}`, `--banner-bg-a/b`, `--modal-backdrop` and `--elevated-shadow`, so modals, the command palette, dropdowns, subagent/ultracode windows, file previews and the mobile sheets follow the skin instead of hardcoded near-black rgba. ⚠️ Every skin that wants its own elevated look must override these — a skin that omits `--floating-bg` silently inherits the `:root` value, which is how the OG skin's near-black modals drifted slate. `styles.css` also defines **compatibility aliases** (`--bg-primary/secondary/tertiary`, `--text-primary/secondary`, `--border-color`, `--accent-color`, `--success`, `--error`, `--danger`, `--font-mono`, `--shadow-lg`) that forward to the canonical tokens; panels written against those names previously resolved to *nothing* (invalid at computed-value time), so the aliases are load-bearing, not cosmetic. + +### Custom branding and UI language + +**Custom branding + UI language** (App Settings → Display → Branding & Language): `displayName` is schema-validated (trimmed, 1–40 chars), server-synced, and changes user-facing browser branding/window titles only — NEVER rename npm package/CLI/API/storage/CSS/protocol identifiers. `language` is a per-device `en`/`zh-CN` display key, stripped from the server payload. `i18n.js` keeps English as the canonical source/fallback, observes newly inserted application DOM for dynamic copy, preserves source strings so live EN↔ZH switching is reversible, and skips terminal/response/file/session-name/user-content surfaces. User display names flow through `textContent`/attribute APIs and the server title's HTML escaper, never `innerHTML`. + +### Foldable settings identity + +**Foldable settings identity**: responsive layout remains width-driven through `MobileDetection.getDeviceType()`, but the localStorage namespace/defaults use `MobileDetection.isHandheldDevice()` so an Android foldable keeps `codeman-app-settings-mobile` after unfolding past the desktop breakpoint. The stable handheld check prefers explicit phone/tablet/desktop UA tokens, then `navigator.userAgentData.mobile`; Android WebView is covered by the `Mobile` UA fallback. Do not switch per-device settings namespaces from instantaneous viewport width — a posture-triggered WebView reload would lose opt-in UI such as `showResponseViewer` and `extendedKeyboardBar`.

Hook curls cat the secret file at exec time via `$CODEMAN_HOOK_SECRET_FILE` (session env, `config/hook-secret.ts`); a missing/wrong secret gets 401 and rate-limits in a dedicated bucket (never locks out login).

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**.

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-.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). diff --git a/docs/images/subagent-demo.gif b/docs/images/subagent-demo.gif deleted file mode 100644 index e2fc33fe..00000000 Binary files a/docs/images/subagent-demo.gif and /dev/null differ diff --git a/docs/images/subagent-demo.mp4 b/docs/images/subagent-demo.mp4 deleted file mode 100644 index 44c4209d..00000000 Binary files a/docs/images/subagent-demo.mp4 and /dev/null differ diff --git a/docs/images/zerolag-demo-reddit.mp4 b/docs/images/zerolag-demo-reddit.mp4 deleted file mode 100644 index feb8642a..00000000 Binary files a/docs/images/zerolag-demo-reddit.mp4 and /dev/null differ diff --git a/docs/screenshots/mobile-session-keyboard-20260727.png b/docs/screenshots/mobile-session-keyboard-20260727.png new file mode 100644 index 00000000..de8897e0 Binary files /dev/null and b/docs/screenshots/mobile-session-keyboard-20260727.png differ diff --git a/docs/screenshots/mobile-toolbar-enter-20260727.png b/docs/screenshots/mobile-toolbar-enter-20260727.png new file mode 100644 index 00000000..6df25e7e Binary files /dev/null and b/docs/screenshots/mobile-toolbar-enter-20260727.png differ diff --git a/docs/security-architecture.md b/docs/security-architecture.md index eed56507..85a23ad4 100644 --- a/docs/security-architecture.md +++ b/docs/security-architecture.md @@ -500,6 +500,16 @@ Full feature guide: [`docker-cases.md`](docker-cases.md). --- +## 10b. Web tabs (dashboard proxy) + +A saved dashboard URL renders as a tab, served through Codeman's own origin at `/webview//`. User guide: [`web-tabs.md`](web-tabs.md). Three properties carry the security weight: + +- **The proxy is exempt from cookie auth and the Origin/CSRF guard, and that is deliberate.** The iframe is sandboxed without `allow-same-origin`, so it is opaque‑origin: its requests are cross‑site, meaning the `SameSite=lax` session cookie is never attached and its writes and WS upgrades arrive with `Origin: null`. The credential is instead a 192‑bit capability in the path, minted only by an authenticated `POST /api/webviews/:id/open`, held in memory (a restart invalidates every one), rolling TTL, bound to the minting user, and granting nothing but "relay bytes to this one saved URL". ⚠️ **The Host allowlist is NOT bypassed**, so DNS‑rebinding protection is unaffected. A second `Referer`‑keyed form exists for root‑absolute assets and is the only exemption decided by a request‑supplied header, so it is fenced to safe methods on non‑`/api`, non‑`/ws`, non‑`/q` paths. Edges pinned by `test/webview-auth-exemption.test.ts`. +- **Sandboxed by default; `allow-same-origin` is an explicit per‑dashboard opt‑in.** A proxied page is same‑origin with Codeman, so without the sandbox its JavaScript could read the Codeman document and call the agent‑spawning API. ⚠️ In BOTH modes the `Authorization` header and the `codeman_session` cookie are stripped before the upstream request, because a trusted (same‑origin) frame makes the browser attach Codeman's own Basic‑auth credentials to every proxied request; forwarding them would hand `CODEMAN_PASSWORD` to the dashboard. +- **Not an open relay, and not a privilege boundary.** `resolveUpstreamUrl()` refuses anything leaving the saved origin, and cross‑origin redirects are handed back unchanged rather than followed. The proxy does reach whatever the SERVER can reach, which is not an escalation for someone who already commands `--dangerously-skip-permissions` agents, but in multi‑user mode it means a non‑admin's dashboard is fetched from the server's network position. Saved URLs are validated to plain http(s) with no embedded credentials, and there is deliberately **no magic‑link path**: terminal output can never create a webview (the mistake the attachment scanner had to be walled off from). + +--- + ## 11.
