## What changed

Stopping Chopin now reaches a question that is waiting for an answer. The waiting question is cancelled, the active work state ends, and the next queued chat request can proceed. Repeated clicks on Stop record one stop notice rather than stacking copies, including while a retained workflow reports delayed progress. If session cleanup fails, the chat still settles its transcript and drains the queue.

The active row now labels its time **Started at**. That makes a long-running turn's original timestamp clear instead of implying the work just happened.

## Why

The question tool was waiting without receiving the turn's cancellation signal. The agent stream could therefore remain open after Stop, leaving Chat busy and blocking later requests. The diagram shows the repaired path.


## Verification

- A real Harness regression covers an open question, two Stop attempts, cancellation, settled tool status, queue recovery, and both successful and failed session cleanup. Separate regressions cover concurrent and delayed Stop clicks while retained workflows pause. - The full unit suite (3,624 passed) ran on the original branch. After rebasing, 165 chat tests, focused Stop regressions, TypeScript and formatting/lint checks, and three Chromium chat tests passed. All three GitHub CI jobs, including the full browser suite, passed on this PR. - A separate agent reviewed the server and client changes, then re-reviewed the queue, timestamp, and retained-workflow fixes with no remaining finding.

The repair targets the observed waiting-question deadlock. A third-party session cleanup that never returns still requires a separate recovery design before the server can safely run another tool session.

Merged `main` and resolved the transcript conflict in merge commit `88d9aac`. The branch’s active-turn “Started at” timestamp is preserved with `main`’s updated transcript styling.

Root cause: `bun run ci` in failed run `37621259944` stopped in `dprint check` on one misindented ternary line in `apps/web/src/chat/transcript.tsx` (`Started at ...` branch in the active-row timestamp).

Queued for guarded application: one `[ci-fix]` commit updating `apps/web/src/chat/transcript.tsx`. GitHub CI still needs to confirm it after the queued push lands.

Verified here: - `git diff --check` : pass - `bun run types` : pass - `bun run ci` : blocked locally because this environment cannot fetch dprint's remote WASM plugins (`Proxy failed to connect`), but the failed GitHub log already isolated the only formatter diff to this file.
