fix(terminal): partial-history notice only when there is history to load

The "Showing the most recent 1.0 MB of this session. 4.8 MB more may still
be retained." bar covered the top of the terminal on nearly every tab switch,
and for fullscreen claude panes it could never be acted on: `truncated`
measures the server's byte stream, while Load full history asks tmux, which
holds no scrollback for a pane that lives in the alternate screen.

- The capture reads `#{history_size}` in the cursor query it already makes
  and the terminal route returns it as `paneHistoryLines`.
- A reported 0 hides the notice; a positive count replaces the byte gap in
  the message.
- The notice is lazy: it appears once a wheel/touch gesture reaches the top
  of the browser buffer (after the pull that gesture starts), leaves when
  the user scrolls back to live output or switches tabs, and its dismissal
  sticks per session until reload.
- formatHistoryBytes no longer prints "1024 KB" just under 1 MiB.

+The "Showing the most recent 1.0 MB of this session" notice no longer appears on every tab switch. It shows up only when you scroll to the top of a terminal, leaves when you scroll back down, and stays closed for that tab once you dismiss it. Sessions with nothing more to load (fullscreen Claude, whose history lives in Claude itself) never show it, and when there is more, it states the scrollback line count instead of an inflated byte figure. `GET /api/v1/sessions/:id/terminal` reports the new `paneHistoryLines` field.

-Tiles move by hand, and can leave the window. With gesture control on, pinch a tile and carry it onto another tile (they swap) or an empty cell (it moves there), or carry a tab onto the grid to tile it. A new **Detach Tiles** setting (App Settings → Appearance, per device, off by default) lets you drag a tile's header out of the browser to open it in its own window, drop it on another Codeman window's tiles to move it there, and drag a popped-out window's title back onto any grid. The tile's ⋯ menu gets "Open in a new window" too.

-- 87f1c9c: ### Thanks
-  - @Randalix for `codeman agent` (#557), the session verbs (`ls`, `spawn`, `send`, `wait`, `read`, `interrupt`, `rm`) for agents in every CLI mode, and for moving every test server onto an ephemeral port (#570), which finishes #440. Thanks also for reporting and fixing git's clone errors on non-English hosts (#568, shipped as #572 with your commit).
-  - @opticon454 for five PRs: MCP server sync for GitHub Copilot CLI (#581), an Apply button that saves Settings without closing them (#565), configurable toast and browser-notification display times (#564), in-document links in rendered markdown that scroll to their heading (#563), and npm-based CLI installs that work when the system npm prefix is root-owned (#562).
-  - @JDProfresh for three PRs: pasted and uploaded files moving into a hidden, self-ignoring `.codeman-uploads/` folder (#574, after your #553 proposal), local echo that keeps painting on phones when the view sits above the bottom (#576), and upload failures that say why they failed (#578).
-  - @aakhter for session search on the vertical tab rail (#580), built on the sidebar's existing filter instead of a second one, and for keeping alerted tabs visible during a search.

-  ![Codeman tile grid: six live agents powering on and off with the CRT tile animation](https://raw.githubusercontent.com/Ark0N/Codeman/08694b5862534b2b1224e9e272ad9858c787ebef/release-1.41/tiles-crt-stats-800.gif)
-
-  **Tile Animations (#571).** The tile grid from 1.40.0 can now open with a show. App Settings has a new **Animations** section (right after Appearance) that holds every animation setting: the Entrance Theme (moved out of Appearance), the new **Tile Animations** row, and a button that opens the animation lab. Tile styles: **CRT** (each tile switches on as a hot line in a diagonal wave, and switches off to a line and a dot), **Fly from tab** (each tile grows out of its session tab and flies back into it), **Deal** (dealt out of the Tiles button like cards), **Beam down**, **Cascade**, **Pop**, **Soft** and **None**. A styled tile plays in two beats: the frame enters in the tile style, then its screen powers on in the terminal style of your Entrance Theme. Picking a theme presets a matching tile style, and a new **Launch** theme flies the tiles out of their tabs. Off by default (the grid keeps its quick fade), per device, nothing moves under reduced motion, and the animations never cost an extra PTY resize. The terminal pane's Boot entrance style is gone; a saved Boot falls back to off.
-
-  **Tiles open the sessions you care about, and keep your layout.** With no grid arranged yet, the Tiles button (or `Ctrl+Shift+G`) now fills the grid with the sessions that are working first (most recently started first), then the ones waiting on you (a permission prompt or a finished turn you have not seen), then the most recently used, instead of the tabs in strip order, which opened the oldest ones. The session you are on is still always included. Once you arrange a grid (which session sits where, empty cells, the tile count, divider sizes, the focused and zoomed tile), that layout is remembered in this browser and the Tiles button brings it back exactly, however the grid was closed, and so does a reload while it was open. A session that has gone since frees its place, which the same ranking fills. A grid larger than the window opens in full with the focused tile zoomed, instead of being trimmed (and losing the rest of your layout).
-
-  **The wheel scrolls Claude inside a tile (#577).** In a tile or the split's second pane, a Claude session on its fullscreen renderer now scrolls its own conversation with the mouse wheel, exactly like the main terminal: the wheel goes to Claude as mouse reports, aimed at that tile's session and computed from the tile's own screen. Before, the wheel did nothing or scrolled the stale frames left over from loading the tile. Shift+wheel (scroll local history) works in every tile on Windows and Linux too; it was dead there.
-
-  **`codeman agent`: session verbs for every CLI (#557).** Agents in any mode (Codex, OpenCode, Gemini, Pi and the rest, not just Claude) can now drive other Codeman sessions from the command line: `codeman agent ls | spawn | send | wait | read | interrupt | rm`. It is a thin client over the existing session API: every call names the session that made it, `wait` blocks on a signal (`--until stop,exit`) or a literal output marker (`--match`), and exit codes say what happened (`0` ok, `1` error, `2` timeout, `3` exited, `4` refused). Ids shorter than 8 characters are refused, so a stray `rm 9` can never pick a session at random, and `rm` never deletes the session it runs in. See the README section "`codeman agent`" and the wiki page Driving Codeman From An Agent. This is phase 1 of #445.
-
-  **Settings: Apply (#565).** Next to Save, an Apply button saves the same way but keeps Settings open. Switching on MCP server sync makes its Preview and Sync usable straight away, and CLI management's add, enable and disable work without closing and reopening Settings.
-
-  **MCP server sync reaches GitHub Copilot CLI (#581).** With MCP server sync on (App Settings, off by default), Copilot CLI's `~/.copilot/mcp-config.json` now takes part like the agent CLIs' own files: its servers are copied to the others and theirs to it, additively, with the previous file kept as `.codeman-bak`. Copilot joins only when it is installed or already has that file, a server switched off in Copilot is never copied, and `COPILOT_HOME` is followed. Copilot is a sync target only, not a new run mode.
-
-  **Notifications stay up longer if you want (#564).** Settings → Notifications has a Toast display time and a Browser notification display time (1 second to 5 minutes, per device; the defaults stay 3 s and 8 s).
-
-  **CLI logos on tabs can be switched off (#569).** App Settings → Appearance → Tabs → **CLI Logos on Tabs** hides the agent logo on every tab surface (header strip, rails, sidebar, phone chips, the desktop home list) on this device. On by default. Tile headers, split pane headers and the Run menus keep their logos.
-
-  **Search sessions on the vertical rail (#580).** The vertical tab rail has a **Search sessions** box at the top: type part of a name and the rail narrows to the tabs that match (a web tab by its title), across every group, collapsed ones included, without touching your groups, their collapse or the tab order. A tab with an alert stays visible even when its name does not match, so a prompt waiting on you is never filtered away. Escape or × clears it, you can still drag a found tab into a group, and nothing is saved. The sidebar's filter box shares the same filter: a tab with an alert stays visible there too, and in the by-case tab layout a case with no match now hides.
-
-  **Closing a tab is instant.** Closing a session used to take half a second or more before the tab went away. The tab, tile or split pane now goes (and the next session is selected) the moment you click, while the server shuts the session down in the background, and the server side is faster too (about 450 ms down to 200-260 ms for a Claude session): it no longer sleeps fixed intervals, no longer freezes for about 70 ms per close on a synchronous tmux call, and scans for a session's subagents once instead of once per subagent. If the server refuses the close, the tab comes back where it was with the error. This also fixes a bug where a failed close still said "Session closed" while the session kept running.
-
-  **Fixes.**
-  - **Clone errors on non-English hosts (#572, from #568).** Cloning a repository as a case now classifies a failed clone correctly whatever the host's language: a missing branch or tag is "does not exist on the remote" (400) and a missing repository is a 404, instead of a generic 422 with git's German (or any other) error text. Git runs with `LC_ALL=C` for clones and repo status, so the repo status card's error text is English on every host as well.
-  - **Links within a markdown file (#563).** A link to another heading of the same document (`[Install](#installation)`) in the File Viewer or Response Viewer scrolls to that heading instead of doing nothing. Headings get GitHub-style slugs, repeated titles are numbered, and non-ASCII headings work.
-  - **npm CLI installs on a root-owned prefix (#562).** Installing an npm-based CLI from Settings (DeepSeek's `dsh`, pi, ...) no longer fails with EACCES when the system node keeps its global prefix under `/usr`: the install goes to `~/.local`, where Codeman already looks for CLIs. A prefix you set yourself, or one you can write to, is left alone, including when Codeman runs under `npm run`.
-  - **Uploads go to a hidden `.codeman-uploads/` folder (#574).** Images you paste or upload into a prompt are saved in `<workspace>/.codeman-uploads/` instead of `.claude-images/`. The folder ignores itself in git (it carries a `.gitignore` of `*`), stays hidden in the Files panel, and is cleaned up as before: files older than 7 days in an hourly sweep, and the folder when the last session in that workspace closes. The old `.claude-images/` folder gets nothing new and is still swept and removed during 1.41.x. An upload to a remote (SSH) session is now refused with a clear message, since the file would land on the Codeman host where the remote agent cannot read it.
-  - **Typing on a phone after a tab switch (#576, fixes #575).** With local echo on (the default on touch devices), text typed while the terminal sat above the bottom was buffered but never painted, so the keyboard looked dead. The view sits there after every tab switch and after the keyboard closes. The overlay now paints whenever the prompt row is on screen, and hides only when you scroll the prompt out of view.
-  - **Upload failures say why (#578).** When a prompt image upload fails, the toast shows the server's reason (for example a rate limit) instead of only "1 failed".
-  - **The npm page shows the English README.** npmjs.com had been rendering the Chinese README, because npm picks the package's readme from an unsorted file match at publish time. The publish now moves `README.zh-CN.md` aside while it runs (the file and every link to it stay as they are), and the package description and homepage say what Codeman is and point at getcodeman.com.
-  - **New cases ask for clickable file paths.** The CLAUDE.md generated into a new case asks the agent to report every file it created as a full absolute path, which Codeman turns into a link that opens the File Viewer, and mentions the codeman skill for starting and managing worker sessions.
-
-  **For contributors (#570).** Every in-process test server binds an ephemeral port, the mobile suite included, and the port guard now also refuses raw listeners on a fixed port, so two test runs on one machine never collide.
-
-  **Fixes applied while landing.** zh-CN translations for the two new notification display-time settings and for the new Animations section. A session whose name matches an interface word ("Lab", "New session") is no longer translated in the tab strip when the interface is in Chinese. Plus test and doc cleanups left over from review.

-### `codeman agent` — session-to-session verbs in every CLI mode
-
-The skill above is claude-shaped (Codeman seeds its preamble for claude sessions only). An `opencode`, `codex`, `pi` or `gemini` agent has the same environment (`CODEMAN_MUX=1`, `CODEMAN_SESSION_ID`, `CODEMAN_API_URL` are exported into every pane) but nothing that teaches it the verbs — so `codeman agent` packages them as commands. It is a thin client over the endpoints listed under [API](#api): no new route, no new transport, auth and ownership unchanged. One line in a case's `AGENTS.md` is enough: *"other sessions: `codeman agent --help`"*.
-
-```bash
-codeman agent ls                                          # sessions; * marks this one
-SID=$(codeman agent spawn scratch-1 --mode claude)        # quick-start + wait for the composer where the mode has a ready mark
-codeman agent send "$SID" 'review src/, then say DONE' --until stop,exit --timeout 300000   # --wait = default signal set
-codeman agent read "$SID"                                 # last answer (as the server reads it for that mode)
-codeman agent read "$SID" --tail 3000                     # terminal tail, ANSI stripped (every mode)
-codeman agent send "$SID" 'run the tests, then print WORKDONE followed by _4711'   # hook-less modes (opencode, pi, …): ask for the marker in halves …
-codeman agent wait "$SID" --match WORKDONE_4711           # … and wait on the joined form, which the prompt's echo never contains
-codeman agent interrupt "$SID"                            # a bare ESC, conversation intact
-codeman agent rm "$SID"                                   # any session except this one
-```
-
-Rules the commands enforce rather than document: they refuse outside a Codeman session and never guess a URL; `send` transmits printable text plus Enter only (a control byte such as `Ctrl+C` is `app_exit` in opencode — ESC exists solely as `interrupt`, which never appends Enter); `rm` refuses an empty id, an unprovable self id and a prefix match in either direction. Ids may be the 8-character prefixes `ls` prints (resolved through the list; an ambiguous prefix refuses, anything shorter than 8 characters refuses on every verb). A prompt that starts with `-` goes after `--` (`send "$SID" -- "- fix the bug"`). The echo of the prompt you sent is output too: a `--match` marker that appears verbatim in the prompt matches at once, before the worker has done anything, so the prompt asks for it in halves. A remote session whose host is asleep answers a fire-and-forget `send` with `buffered` (Codeman wakes the host and types the prompt once the pane is back) or `dropped` (over the wake buffer's cap, nothing will be typed: exit `1`). Exit codes: `0` delivered/matched/signal, `1` error, `2` timeout, `3` the worker exited or the wait ended without an answer (`delivered:false`, `ended:true`), `4` refused. `spawn` prints the id alone on stdout (prose goes to stderr), so `SID=$(…)` captures exactly the id. `--json` prints the envelope's `data` for every verb. `--until stop` on a mode without hook signals is the server's 400, passed through — the marker path (`--match`) is the answer there, exactly as for the skill.
-
 ### Hooks (events flowing _back_ to Codeman)
 
 Codeman registers Claude Code hooks that `POST /api/hook-event` (`permission_prompt`, `idle_prompt`, `stop`, `task_completed`, …) so the dashboard reacts in real time. This endpoint is auth-exempt on loopback but, under a managed tunnel, requires the `X-Codeman-Hook-Secret` header (read it from `$CODEMAN_HOOK_SECRET_FILE`). You normally don't call this by hand — Codeman wires it up — but it's how the autonomy layers "see" what the agent is doing.

-## The `codeman agent` CLI (client over these endpoints)
-
-`codeman agent ls|spawn|send|wait|read|interrupt|rm` (`src/cli-agent.ts`) is the command-line client for the endpoints above, for agents in modes that never receive the claude-only skill preamble. It adds no route: `spawn` is `POST /api/v1/quick-start` (+ `wait-output` on the mode's `capabilities.composerReadyMark` from the CLI registry, where it declares one), `send` is `POST …/input` with `clientId`+`seq` (and `wait`/`waitTimeout` for `--wait` / `--until <signals>`; `delivered:false` without `duplicate` and `wait.ended` both exit 3 — the CLI never reports a dead worker as done), `wait` is `GET …/wait` (`--until`) or `GET …/wait-output` (`--match`, `from=buffer` by default), `read` is `GET …/last-response` or `GET …/terminal?tail=`, `interrupt` is `POST …/input` with a bare `\u001b`, `rm` is `DELETE …/sessions/:id`. A fire-and-forget `send` to a sleeping wake-on-LAN host reads the route's `buffered` (own line, exit 0) and `dropped` (exit 1: the chunk is gone). An id may be the 8-character form `ls` prints, resolved through `GET /api/v1/sessions`; anything shorter refuses before any request, the same floor as `PARENT_SESSION_ID_MIN_PREFIX`. Every call carries `X-Codeman-Parent-Session`; only `spawn`'s quick-start carries `X-Codeman-Agent-Origin: codeman-agent-cli` (the agent-scratch label must never reach a request that cannot create the case directory). Basic auth comes from `CODEMAN_PASSWORD` or the data dir's `.env`. Server-side error codes are shown verbatim (`INVALID_INPUT: until=stop …` on a hook-less mode is not hidden); exit codes are `0` ok, `1` error, `2` timeout, `3` the session exited, `4` refused by a client-side guard. See the README section "`codeman agent`" for the guards and `test/cli-agent.test.ts` for the pinned behaviour.

-`.gitignore` containing `*` (written once, never over a file already there), and

-that folder receives nothing new, and is swept and removed the same way for one
-release. A remote (SSH) session answers 400, since the file would land on the
-Codeman host under a path the remote agent cannot read. A Docker session of an
-owned case is fine, its workspace is bind-mounted at the same absolute path; an
-adopted container (`owned: false`) mounts nothing, so its agent can open the file
-only if the container itself exposes that host path.

-**Tools that are not run modes.** GitHub Copilot CLI keeps an MCP list worth syncing but Codeman does not launch it, so it has no registry entry. `src/mcp-sync-targets.ts` declares such tools as plain data (`MCP_SYNC_ONLY_TOOLS`: id, label, config path, dialect, relocation var, the binary whose presence means "installed"). They join the registry CLIs as sync targets (listed after them, so a registry CLI's definition wins a same-name difference), under the same rules: installed or already configured, otherwise `absent`. Copilot's dialect is `copilot-json` (`~/.copilot/mcp-config.json`, relocated by `COPILOT_HOME`; checked against `copilot mcp add` 1.0.94): `mcpServers`, each entry with `tools` (`["*"]` = all), `type` `local` | `http` | `sse`, `command`/`args`/`env` or `url`/`headers`. `copilot mcp disable` does not mark the entry: it lists the name under `disabledMcpServers` in `settings.json` beside the config. Sync reads that list (never writes it) so a disabled server is not copied, and reports the target `unreadable` if `settings.json` is not valid JSON rather than guessing.

The var is read from the SERVER process env at call time, which is the env the CLIs Codeman spawns inherit. An absolute value moves the file to `<value>/<relocation.path>`, an empty one counts as unset (as it does for each CLI), and anything else reports the target `skipped` with the reason instead of writing a file the CLI never reads.

 The rules the module keeps and the tests pin: it only ADDS (a name already defined, in any shape, is never edited or removed; a same-name difference is reported as a conflict); a server switched off in its own CLI is not copied; it never writes a file it could not parse (opencode JSONC with comments, a TOML file with a duplicate table) and re-parses the new text before writing; codex TOML is read with a real parser (`smol-toml`), so CRLF files and inline tables are handled; names such as `__proto__` are ignored and every table keyed by an untrusted name has no prototype; a symlinked config is written through, not replaced; a file that receives `env`/`headers` is left `0600`; only one apply runs at a time; and its result carries server names only, never env values or headers, and never file text: a parse failure is reported by line and column, not by the parser's message (smol-toml prints a code frame of the offending lines and V8's JSON errors quote source, either of which can hold a secret). The schema restricts `path` and `relocation.path` to a relative path without `..`, since sync writes to it.

-- 87f1c9c: ### Thanks
-  - @Randalix for `codeman agent` (#557), the session verbs (`ls`, `spawn`, `send`, `wait`, `read`, `interrupt`, `rm`) for agents in every CLI mode, and for moving every test server onto an ephemeral port (#570), which finishes #440. Thanks also for reporting and fixing git's clone errors on non-English hosts (#568, shipped as #572 with your commit).
-  - @opticon454 for five PRs: MCP server sync for GitHub Copilot CLI (#581), an Apply button that saves Settings without closing them (#565), configurable toast and browser-notification display times (#564), in-document links in rendered markdown that scroll to their heading (#563), and npm-based CLI installs that work when the system npm prefix is root-owned (#562).
-  - @JDProfresh for three PRs: pasted and uploaded files moving into a hidden, self-ignoring `.codeman-uploads/` folder (#574, after your #553 proposal), local echo that keeps painting on phones when the view sits above the bottom (#576), and upload failures that say why they failed (#578).
-  - @aakhter for session search on the vertical tab rail (#580), built on the sidebar's existing filter instead of a second one, and for keeping alerted tabs visible during a search.
-
-  ![Codeman tile grid: six live agents powering on and off with the CRT tile animation](https://raw.githubusercontent.com/Ark0N/Codeman/08694b5862534b2b1224e9e272ad9858c787ebef/release-1.41/tiles-crt-stats-800.gif)
-
-  **Tile Animations (#571).** The tile grid from 1.40.0 can now open with a show. App Settings has a new **Animations** section (right after Appearance) that holds every animation setting: the Entrance Theme (moved out of Appearance), the new **Tile Animations** row, and a button that opens the animation lab. Tile styles: **CRT** (each tile switches on as a hot line in a diagonal wave, and switches off to a line and a dot), **Fly from tab** (each tile grows out of its session tab and flies back into it), **Deal** (dealt out of the Tiles button like cards), **Beam down**, **Cascade**, **Pop**, **Soft** and **None**. A styled tile plays in two beats: the frame enters in the tile style, then its screen powers on in the terminal style of your Entrance Theme. Picking a theme presets a matching tile style, and a new **Launch** theme flies the tiles out of their tabs. Off by default (the grid keeps its quick fade), per device, nothing moves under reduced motion, and the animations never cost an extra PTY resize. The terminal pane's Boot entrance style is gone; a saved Boot falls back to off.
-
-  **Tiles open the sessions you care about, and keep your layout.** With no grid arranged yet, the Tiles button (or `Ctrl+Shift+G`) now fills the grid with the sessions that are working first (most recently started first), then the ones waiting on you (a permission prompt or a finished turn you have not seen), then the most recently used, instead of the tabs in strip order, which opened the oldest ones. The session you are on is still always included. Once you arrange a grid (which session sits where, empty cells, the tile count, divider sizes, the focused and zoomed tile), that layout is remembered in this browser and the Tiles button brings it back exactly, however the grid was closed, and so does a reload while it was open. A session that has gone since frees its place, which the same ranking fills. A grid larger than the window opens in full with the focused tile zoomed, instead of being trimmed (and losing the rest of your layout).
-
-  **The wheel scrolls Claude inside a tile (#577).** In a tile or the split's second pane, a Claude session on its fullscreen renderer now scrolls its own conversation with the mouse wheel, exactly like the main terminal: the wheel goes to Claude as mouse reports, aimed at that tile's session and computed from the tile's own screen. Before, the wheel did nothing or scrolled the stale frames left over from loading the tile. Shift+wheel (scroll local history) works in every tile on Windows and Linux too; it was dead there.
-
-  **`codeman agent`: session verbs for every CLI (#557).** Agents in any mode (Codex, OpenCode, Gemini, Pi and the rest, not just Claude) can now drive other Codeman sessions from the command line: `codeman agent ls | spawn | send | wait | read | interrupt | rm`. It is a thin client over the existing session API: every call names the session that made it, `wait` blocks on a signal (`--until stop,exit`) or a literal output marker (`--match`), and exit codes say what happened (`0` ok, `1` error, `2` timeout, `3` exited, `4` refused). Ids shorter than 8 characters are refused, so a stray `rm 9` can never pick a session at random, and `rm` never deletes the session it runs in. See the README section "`codeman agent`" and the wiki page Driving Codeman From An Agent. This is phase 1 of #445.
-
-  **Settings: Apply (#565).** Next to Save, an Apply button saves the same way but keeps Settings open. Switching on MCP server sync makes its Preview and Sync usable straight away, and CLI management's add, enable and disable work without closing and reopening Settings.
-
-  **MCP server sync reaches GitHub Copilot CLI (#581).** With MCP server sync on (App Settings, off by default), Copilot CLI's `~/.copilot/mcp-config.json` now takes part like the agent CLIs' own files: its servers are copied to the others and theirs to it, additively, with the previous file kept as `.codeman-bak`. Copilot joins only when it is installed or already has that file, a server switched off in Copilot is never copied, and `COPILOT_HOME` is followed. Copilot is a sync target only, not a new run mode.
-
-  **Notifications stay up longer if you want (#564).** Settings → Notifications has a Toast display time and a Browser notification display time (1 second to 5 minutes, per device; the defaults stay 3 s and 8 s).
-
-  **CLI logos on tabs can be switched off (#569).** App Settings → Appearance → Tabs → **CLI Logos on Tabs** hides the agent logo on every tab surface (header strip, rails, sidebar, phone chips, the desktop home list) on this device. On by default. Tile headers, split pane headers and the Run menus keep their logos.
-
-  **Search sessions on the vertical rail (#580).** The vertical tab rail has a **Search sessions** box at the top: type part of a name and the rail narrows to the tabs that match (a web tab by its title), across every group, collapsed ones included, without touching your groups, their collapse or the tab order. A tab with an alert stays visible even when its name does not match, so a prompt waiting on you is never filtered away. Escape or × clears it, you can still drag a found tab into a group, and nothing is saved. The sidebar's filter box shares the same filter: a tab with an alert stays visible there too, and in the by-case tab layout a case with no match now hides.
-
-  **Closing a tab is instant.** Closing a session used to take half a second or more before the tab went away. The tab, tile or split pane now goes (and the next session is selected) the moment you click, while the server shuts the session down in the background, and the server side is faster too (about 450 ms down to 200-260 ms for a Claude session): it no longer sleeps fixed intervals, no longer freezes for about 70 ms per close on a synchronous tmux call, and scans for a session's subagents once instead of once per subagent. If the server refuses the close, the tab comes back where it was with the error. This also fixes a bug where a failed close still said "Session closed" while the session kept running.
-
-  **Fixes.**
-  - **Clone errors on non-English hosts (#572, from #568).** Cloning a repository as a case now classifies a failed clone correctly whatever the host's language: a missing branch or tag is "does not exist on the remote" (400) and a missing repository is a 404, instead of a generic 422 with git's German (or any other) error text. Git runs with `LC_ALL=C` for clones and repo status, so the repo status card's error text is English on every host as well.
-  - **Links within a markdown file (#563).** A link to another heading of the same document (`[Install](#installation)`) in the File Viewer or Response Viewer scrolls to that heading instead of doing nothing. Headings get GitHub-style slugs, repeated titles are numbered, and non-ASCII headings work.
-  - **npm CLI installs on a root-owned prefix (#562).** Installing an npm-based CLI from Settings (DeepSeek's `dsh`, pi, ...) no longer fails with EACCES when the system node keeps its global prefix under `/usr`: the install goes to `~/.local`, where Codeman already looks for CLIs. A prefix you set yourself, or one you can write to, is left alone, including when Codeman runs under `npm run`.
-  - **Uploads go to a hidden `.codeman-uploads/` folder (#574).** Images you paste or upload into a prompt are saved in `<workspace>/.codeman-uploads/` instead of `.claude-images/`. The folder ignores itself in git (it carries a `.gitignore` of `*`), stays hidden in the Files panel, and is cleaned up as before: files older than 7 days in an hourly sweep, and the folder when the last session in that workspace closes. The old `.claude-images/` folder gets nothing new and is still swept and removed during 1.41.x. An upload to a remote (SSH) session is now refused with a clear message, since the file would land on the Codeman host where the remote agent cannot read it.
-  - **Typing on a phone after a tab switch (#576, fixes #575).** With local echo on (the default on touch devices), text typed while the terminal sat above the bottom was buffered but never painted, so the keyboard looked dead. The view sits there after every tab switch and after the keyboard closes. The overlay now paints whenever the prompt row is on screen, and hides only when you scroll the prompt out of view.
-  - **Upload failures say why (#578).** When a prompt image upload fails, the toast shows the server's reason (for example a rate limit) instead of only "1 failed".
-  - **The npm page shows the English README.** npmjs.com had been rendering the Chinese README, because npm picks the package's readme from an unsorted file match at publish time. The publish now moves `README.zh-CN.md` aside while it runs (the file and every link to it stay as they are), and the package description and homepage say what Codeman is and point at getcodeman.com.
-  - **New cases ask for clickable file paths.** The CLAUDE.md generated into a new case asks the agent to report every file it created as a full absolute path, which Codeman turns into a link that opens the File Viewer, and mentions the codeman skill for starting and managing worker sessions.
-
-  **For contributors (#570).** Every in-process test server binds an ephemeral port, the mobile suite included, and the port guard now also refuses raw listeners on a fixed port, so two test runs on one machine never collide.
-
-  **Fixes applied while landing.** zh-CN translations for the two new notification display-time settings and for the new Animations section. A session whose name matches an interface word ("Lab", "New session") is no longer translated in the tab strip when the interface is in Chinese. Plus test and doc cleanups left over from review.

-/**
- * @fileoverview `codeman agent …` — session-to-session verbs for the agent running
- * inside a Codeman session, in every CLI mode.
- *
- * A thin HTTP client over endpoints that already exist (`quick-start`, `input`,
- * `wait`, `wait-output`, `last-response`, `terminal`, `DELETE sessions/:id`). It
- * invents no route and no transport: everything goes through `CODEMAN_API_URL`, so
- * auth, ownership and the per-session waiter cap apply unchanged. The behaviour is
- * the packaged agent skill's (`skills/codeman`), ported from shell prose into code
- * with tests, so a `codex`/`opencode`/`pi` agent — which never gets the claude-only
- * preamble — has the same verbs from one line in its AGENTS.md.
- *
- * Invariants (each asserted in `test/cli-agent.test.ts`):
- * 1. Refuses outside a Codeman session (`CODEMAN_MUX=1` + `CODEMAN_API_URL`); it
- *    never guesses a URL — a server you are not part of is not yours to drive.
- * 2. `send` transmits printable text plus `\r` only. ESC exists solely as
- *    `interrupt`, which never appends `\r`. A stray control byte is a dead session
- *    in the fullscreen TUIs (opencode's `Ctrl+C` is `app_exit`).
- * 3. `rm` fails closed: empty id, a short self id, or a prefix match in EITHER
- *    direction refuses. Ids appear in full and 8-char form, so equality alone
- *    misses a real combination — and the miss deletes the caller.
- * 4. An id shorter than 8 characters refuses (exit 4) before any request, on every
- *    verb. `9` would resolve to whichever session is alone with that first
- *    character, the user's own interactive tab included.
- *
- * Commands live here as functions returning an exit code, not calling
- * `process.exit`, so the whole surface is unit-testable against a fake server.

+/**
+ * @fileoverview The partial-history notice waits until the user reaches for history.
+ *
+ * Every tab switch after the first replays a 1 MiB TAIL of the session's byte
+ * stream, which is truncated for any session that has run for a while, so the
+ * notice ("Showing the most recent 1.0 MB of this session. 4.8 MB more may still
+ * be retained.") covered the top rows on nearly every switch. Its × only lasted
+ * until the next switch. Now:
+ *   - it appears only once a scroll gesture reaches the top of the browser's
+ *     buffer, after the history pull that gesture starts has settled;
+ *   - a scroll back down to live output retires it, and so does a tab switch;
+ *   - a dismissal sticks for that session until the page reloads.
+ *
+ * Runs the REAL methods (app.js banner + state, terminal-ui.js scroll hook,
+ * constants.js notice decision) in a `vm` against a stub DOM, the same way
+ * shell-scroll-history-pull.test.ts does (no jsdom on this box).
