chore: v2.8.70 — select combobox, chat turn end without Stop, no Stop flicker

Claude Code skips the Stop hook in roughly one turn in fifteen (only the
prompt-suggestion helper's SubagentStop arrives), so the main agent stayed
"working" until the idle Notification a minute later and the chat kept
showing Stop on a finished answer. The transcript's turn_duration entry is
now an end of turn too: one newer than the session's last prompt, read
while main still works with no tool open, lands it in Waiting like Stop.

The chat's Stop button now drops to Send only after every busy signal has
been quiet for 2.5 s (Stop pressed still drops at once), so a spinner line
that comes and goes while the CLI redraws no longer flips it back and forth,
and only the newest "working" read is applied.

-/**
- * @file PetChat.tsx
- * @description The pet's chat window — its whole UI: clicking the pet opens
- * it. Above the conversation sits what the pet knows (`info`: live / waiting /
- * errored, the sessions that need you, Mute, Clear alerts — `SagiInfo.tsx`).
- * Before a chat runs, a question the pet can answer itself (`onLocal`: status,
- * who are you…) is answered right here; anything else — and every message once
- * a chat runs — goes to the AI: the first message starts a
- * session of the user's DEFAULT AI tool (`agenthub.defaultTool`, Claude or
- * Codex — the two with a readable transcript) in the "Sagi" workspace, in its
- * first free tab (`startInFreeTabDetailed`), and the conversation is shown as
- * chat bubbles read from the session's transcript. Follow-ups are typed into
- * that session's pane through a terminal attached OFF-SCREEN (`TerminalView`
- * in a fixed box left of the viewport — `submitToRun` needs a mounted,
- * attached pane, exactly like the workspace's own Chat view), so nothing new
- * reaches the server. A menu the CLI asks with (a permission or trust prompt)
- * is read off that pane and answered with `PaneMenuCard`. The chat is kept in
- * `localStorage` (`agenthub.pet.chat`) while its pane lives, so closing and
- * reopening the window continues it; **New chat** STOPS that session (kills
- * its pane and archives it, asking first only mid-reply), **Open in workspace**
- * opens its pane there. Opening never resumes an ended session: once the pane
- * is gone, the next message starts a new one.

 A **Codex pet** is the `.codex-pet.zip` format Codex Desktop uses (the bundles shared on codex-pets.net and in `mileson/codex-pets`): `pet.json` (`id`, `displayName`, `description`, `spritesheetPath`) and `spritesheet.webp`, a 1536×1872 atlas of 8 columns × 9 rows of 192×208 frames — idle, run right, run left, waving, jumping, failed, waiting, running, review, with 6/8/8/4/5/8/6/6/6 frames — or a v2 atlas (`spriteVersionNumber: 2`, 1536×2288, 11 rows) whose rows 9–10 add 16 gaze poses, 22.5° apart clockwise from straight up. The mascot plays the row of its mood (an agent working → running, waiting for you → waiting, an error → failed, a finished turn → jumping, a live session at rest → review, idle/asleep → idle), and on an event it plays a moment over the mood (a new session → waving, a finish or a pat → jumping, a new subagent → review, a session waiting on you → waiting, an error → failed); dragged it runs left or right with the drag (and along the glide to its edge), hovered it waves, and a v2 pet at idle turns toward the pointer (back to idle 2 s after the pointer rests). Frames play at Codex's own timings (`codex-rs/tui/src/pets/model.rs`: e.g. running 120 ms a frame, its last 220 ms); idle plays at the drawn pace (280/110/110/140/140/320 ms), a sleeping pet at Codex's 6× slower one. Waving, jumping, failed and review are moments — they play three times and settle into idle; running, waiting and the run rows loop. Only the two files are read, at the archive root or one folder deep; an entry's size is checked from the zip's directory before it is inflated; the sheet must be a WebP of exactly one of those sizes (`400 EBADPET` otherwise). An uploaded image is shown still and bobs; SVG is refused because an SVG served from the dashboard's origin runs script.

 **Delete user**: until then a delete answers `502 EPROVISION` ("unknown
 action: delete") and changes nothing.
 
+The same re-run (v2.8.68) keeps members from freezing the box — on 11-02
+some 36 open sessions plus test runs filled RAM and the 4 GB swap on a slow
+disk, and only a hard reset brought it back. The box is for writing code;
+tests run on each member's own machine:
+
+- **Memory.** `agenthub.service` gets `MemoryMax=85%`, `MemorySwapMax=1G`,
+  `OOMPolicy=continue` and `OOMScoreAdjust=-100`. The cgroup holds the server
+  AND every member pane, so memory runs out inside the unit first and the
+  kernel kills one process there by `oom_score_adj`: every command a member's
+  Claude runs is 1000 (`CLAUDE_CODE_SHELL_PREFIX=/opt/agenthub/libexec/tool-run`,
+  which also tells Claude why its command died), a Terminal tab 800, an AI
+  session 300, the dashboard and tmux -100. A test run dies; the session
+  holding the conversation does not. Codex runs its commands without that
+  wrapper, so its commands sit at 300 beside it.
+- **CPU and disk.** `pane-launch` starts every member pane at `nice 10` and
+  best-effort IO priority 7 (the nice cannot be taken back without root), and
+  defaults `VITEST_MAX_THREADS` / `VITEST_MAX_FORKS` to 2.
+- **No tests or containers from Claude.** A synchronous `PreToolUse` hook
+  (`/opt/agenthub/app/scripts/member-guard.js`, Bash only, `ah-*` accounts
+  only) denies `vitest`, `jest`, `phpunit`, `pest`, `pytest`, `npm test`,
+  `npm run test:*`, `php artisan test`, `go test`, `cargo test`, `docker`,
+  `podman`, … and tells Claude to leave testing to the member's machine.
+  A person typing a command in a Terminal tab, and Codex, are not covered.
+  An admin can allow them again with **Settings → AI tools → Tests on this
+  server** (`PUT /api/ai-tools/member-policy` `{allowTests}`, kept in
+  `/opt/agenthub/app/member-policy.json`, no file = blocked); it takes effect
+  at members' next Bash call, no restart.
+- **At most 4 AI sessions per member at once** (`MAX_AI_SESSIONS=<n>` in
+  `/etc/agenthub/server.conf`, `0` = no limit). Counted from the account's
+  running processes (`server/lib/ai-procs.js`: `claude`, `codex`, `agy`,
+  `cursor-agent`, `omp`, a nested one counted once), so a `claude` typed into
+  a Terminal tab counts and the tab itself does not. A new pane past the
+  limit answers `429 ESESSIONLIMIT`; a session started by hand past it has
+  every prompt refused by the guard's `UserPromptSubmit` until another one
+  ends. The host account (admins) is not limited.
+
+The memory caps apply to the running unit at once (the re-run does
+`daemon-reload`); `OOMScoreAdjust`, the session limit on new panes and the
+guard script in `/opt/agenthub/app` arrive with the next restart
+(`sudo -n /usr/bin/systemctl restart --no-block agenthub.service` — panes
+survive, `KillMode=process`). Panes started before the re-run keep their old
+priority. Check with
+`systemctl show agenthub.service -p MemoryMax,MemorySwapMax,OOMPolicy`
+and, in a new member pane, `ps -o ni= -p $$; cat /proc/self/oom_score_adj;
+echo $CLAUDE_CODE_SHELL_PREFIX`.

+/**
+ * @file member-guard.js
+ * @description Server mode, one Linux user per account (S3): the members'
+ * SYNCHRONOUS Claude Code hook, from /etc/claude-code/managed-settings.json
+ * (install-system.sh), run AS the member from /opt/agenthub/app. The box is
+ * shared and small, so it is for writing code only:
+ *
+ *  - `PreToolUse` (matcher Bash): denies a test run or a container command
+ *    (`isHeavy`) — the member commits, pulls the branch on their own machine
+ *    and runs it there. Claude gets the reason and stops trying. An admin
+ *    can allow them again (Settings → AI tools, server/lib/member-policy.js).
+ *  - `UserPromptSubmit`: a member runs at most `MAX_AI_SESSIONS` AI sessions
+ *    at once (server/lib/ai-procs.js). The dashboard refuses a pane past the
+ *    limit itself (ESESSIONLIMIT); this catches a `claude` typed into a
+ *    Terminal tab, by refusing every prompt of a session that is not among
+ *    the account's oldest `limit` ones.
+ *
+ * Only `ah-*` accounts are guarded (the host is an admin's). Fail-open like
+ * every AgentHub hook: any error lets the call through. A person's own
+ * terminal commands and Codex (whose hooks are opt-in) are not covered.
