cmux NEXT session rail: a Background tasks card by teamleaderleo · Pull Request #22368 · manaflow-ai/cmux

teamleaderleo · 2026-10-20T04:16:47Z

Summary

Claude desktop's session panel has a Background tasks card: running commands with how long each has run, a stop button, and how many finished. The cmux NEXT session rail (Debug Settings agent.sessionRail) had no such card.

Now the rail grows a Background tasks card once the chat has a background process. It reads acpmux's process registry (cmux-tui/crates/acpmux/docs/background-processes.md): _acpmux/process/list {sessionId} when the rail shows, then each _acpmux/process_update. The registry holds Claude Code's background shells and Codex's background terminals, so the card is the same for both harnesses.

Running commands, newest first, each with its elapsed time (ticking each second while one runs) and Stop (_acpmux/process/kill). A refused Stop says so and can be tried again; otherwise the row stays until the registry reports the end.
The header counts the running ones (2 running); the card ends with 3 finished.
Five rows show; the rest sit behind Show more.
A reconnect makes a new client, so the source changes with it and the card lists again.

Stacked on #22327 (the Changes card). Until that merges this PR's diff includes its commits; the commits for this card start at 9da29f3.

The gallery entry now covers RailChanges.tsx and RailTasks.tsx (the gallery coverage test listed both as missing).

Testing

bun test test/session-rail-tasks.test.tsx test/session-rail.test.tsx on Huge Blue: the new test file fails on the test commit 9da29f3 (module missing) and all 14 pass on the head. It covers the wire parsing, merging updates, the card (order, elapsed time, Stop, finished count), an update that arrives before the list, a refused list, a chat switch, a new client, and a refused Stop.
bunx vp check on Huge Blue: clean. check:type-scale, check:status-glyphs, check:system-blue pass. check:dialog-keys fails on base (Swift files, not this PR).
Localization: two new keys (rail.running, rail.finished) with all 21 agent-pane locales; reused summary.backgroundTasks, subagents.stop/stopFailed, prDock.more/less.

Changelog

Added: The cmux NEXT session rail shows a Background tasks card with each running background command, how long it has run and a Stop button.

Proof

New tasks variant of the agent-pane.session-rail gallery entry (two running, three finished), rendered from head e383a01 in Playwright WebKit on a fleet Mac (macOS system font). It's a gallery story, not the running app.

Summary by cubic

Updates the cmux NEXT session rail with two cards matching Claude desktop's panel: Background tasks (running commands with elapsed time and Stop, plus a finished count) and Changes (pull requests the chat opened, newest first, with checks, line counts, and Merge/Close state).

The Background tasks card reads acpmux's process registry (_acpmux/process/list when the rail shows, then each _acpmux/process_update), so it works the same for Claude Code and Codex background processes. The Changes card combines the chat's pull requests with what the App reads of the chat folder's current one, so checks and a close-then-reopen show correctly; a close the chat ran wins until a later App read. Both cards show five rows with the rest behind Show more.

Running commands sort newest first with a Stop (_acpmux/process/kill); a refused Stop says so and can be retried. The header counts running commands (2 running) and the card ends with 3 finished.
A reconnect creates a new client, so the process source changes with it and the card subscribes and lists again.
Process updates merge without Array.with for the base's type check.
Stacked on cmux NEXT: session rail Changes card with the chat's pull requests #22327 (the Changes card); commits for this card start at 9da29f3.

Correctness review (independent subagent, Claude Opus 5.5, for owner teamleaderleo) of cedcd7d; fixes in e383a01 (exact head).

Findings and resolution:

Medium: processSource was memoized once, so after a daemon reconnect the card kept its listener on the closed client and never listed again. Fixed: App bumps a client epoch when it sets a new client, and the source changes with it. Test: a refused list keeps what the updates said; another chat starts empty; a new client lists again.
Low: the new client methods split stopSubagent from its doc comment. Fixed.
Low: after an accepted Stop the button stays off until the registry reports the end. Kept: that's the registry's contract (the end arrives as process_update; a harness that exits marks it lost).
Low: the hook and the refused-Stop path had no tests. Added: an update before the list, a refused list, a chat switch, a new client, a refused Stop.

Checked and fine: wire shape (camelCase, ids <sessionId>/<task>), the pane connects as LocalApp so list, kill and process_update are served, the session id is acpmux's, directClient is only read after render, elapsed time, i18n keys, CSS selectors.

Timer rescans command history

RailTasks filters the full process history and sorts the running commands on every one-second tick, even when processes has not changed. The registry keeps finished processes without a history limit, and showing five rows does not bound this work. This violates the repository rule against repeatedly filtering or sorting growing collections in hot UI paths. Cache the running list by processes so timer ticks only update elapsed times.

Rule Used: Flag production code that adds nested full-collection scans, per-target rescans for batch actions, repeated sort/filter/map work in hot UI/socket/search/process paths, in-memory joins that belong in the data store, or unbenchmarked slower algorithms ... (source)

Finished commands stay running

The new process listeners miss changes dropped during _acpmux/lagged. The existing recovery path fetches transcript events, but neither replay nor resyncAfterLag refreshes these listeners. If a command ends in the dropped window, the card keeps showing it as running until the rail is reopened or the connection changes. Refresh the process list after a lag, or replay the missed process records into the same store.

Reopened pull requests stay closed

stateSince only advances when the reported state changes. If a chat closes and reopens a pull request between native reads, both reads report open, so since stays older than closedAt. closedState then keeps showing Closed and hides the checks despite later fresh reads. Track when the status was actually read, rather than when its state first changed, and cover a close/reopen without an intervening closed report.

Adopted and merged. Base merge at bddf2ff: a conflict in direct.ts (base's prompt_accepted/harnesses handlers kept, process_update added) and in the strings catalog (base plus this PR's 5 keys). Array.with replaced, because base's type check rejects it. The independent review PASSED. The reds are base: defaults-snapshot, and the react-apps-check shards (the 6 composer-suggested-prompt tests fail the same way at base 52a1a09; the rest are composer/queue/transcript tests this PR doesn't touch).

Follow-ups from review, not done here:

resyncAfterLag (direct.ts) doesn't list the processes again. If acpmux drops a lagging client's events, a process that ended in the gap stays "running" with a ticking clock, and its Stop gets {}. The fix is for the rail to list again on _acpmux/lagged.
headerState.ts stateSince keeps one entry per PR URL and never removes any.

Base's session rail work (#22368 Background tasks card, its RailTasks, RailChanges and sessionProcesses) is already carried by the Inspector (inspector/TasksSection, ChangesSection, processes.ts), so the rail files base modified or added are removed with the rail, and App.tsx, direct.ts, sessionSummary.ts and summary.css keep the Inspector's side.

Context hides until the harness reports usage and Outputs until the chat produced something, instead of a dash and "None".

The chat's are now acpmux-chat-inspector*.

cmux-next: a reopened pull request leaves the rail's Closed state
