Problem

After a usage-limit stop, during provider compaction, or while a thread is waiting on an awaited command/subagent, follow-ups could not be queued: Send stayed busy, offered Submit/Steer, or started immediately instead of joining the queue.

Expected

Queue follow-ups in those states. They run after the limit continuation, compaction, or background wait finishes. Steer stays unavailable there. The Waiting banner and Stop action remain visible while background work holds the thread.

Approach

Server: queue_after_active waits behind a usage-limited run when no active run exists
Web/mobile: treat compaction and awaited background work as active for follow-up dispatch, without folding that wait into isWorking (which would hide the Waiting banner)
Mobile: detail-derived shells include pending background tasks so Queue still works when the shell stream is unavailable

Web and mobile share the same dispatch rules for one product behavior. Scope is the reported queue regressions; no separate issue was required beyond maintainer direction in this thread.

Test plan

vp run check:changed (format, lint, knip, typecheck, focused tests, react compiler)
Server: queues a message sent with Queue while a usage limit blocks the thread
Web logic: planComposerTurn / composerSendControlBusy for compaction and background wait
Hit a usage limit, Queue a follow-up, Resume — queued message waits for the continuation
While compacting, Queue a message — no stuck spinner; message joins the queue
While Waiting on a command/subagent, Queue a follow-up — banner/Stop stay; Steer not offered

Model/harness: Composer via Cursor / T3 Code.

🟡 Medium components/ChatView.tsx:1473

When an awaited background task is pending, including it in isWorking makes useThreadLifecycle filter pendingBackgroundTasks to []; backgroundWorkNowItem then returns null, hiding the Waiting/task-details banner and its Stop action while the task is still running. Keep the composer/follow-up working state separate from the isWorking value used to present background tasks.

Note

🤖 Composer responding on behalf of wSedlacek

Fixed in 9d0acf4. isWaitingOnBackgroundWork stays a composer-only signal and is no longer folded into isWorking, so useThreadLifecycle still presents the Waiting banner and Stop action.

Approvability

Verdict: Would Approve

Macroscope's review found this PR approvable — Follow-ups now queue during compaction, background waits, and provider limits rather than starting or steering immediately. The reported loss of the Waiting banner and Stop action remains subject to the independent correctness blocking gate.

Needs human approval because:

Walkthrough

The PR updates mobile and web follow-up dispatch during compaction and awaited background work. Server orchestration holds queued messages when pending background work or usage-limited runs block them. Tests and user documentation cover these behaviors.

Changes: Composer follow-up queueing

Layer / File(s)	Summary
Thread state and pending-work derivation `apps/mobile/src/state/use-thread-selection.ts`, `apps/mobile/src/state/use-thread-composer-state.ts`, `packages/shared/src/orchestrationV2PendingBackgroundWork.ts`, `packages/shared/src/orchestrationV2PendingBackgroundWork.test.ts`	Mobile thread details include derived pending background tasks. Mobile state treats compaction and completion-holding background work as busy and prevents steering during background waits. Shared pending-work derivation now handles queued latest runs.
Composer submission and send controls `apps/web/src/components/ChatView.logic.ts`, `apps/web/src/components/ChatView.tsx`, `apps/web/src/components/chat/ChatComposer.tsx`, `apps/web/src/components/chat/composerCommandKey.ts`, `apps/web/src/components/chat/useComposerSend.ts`, `apps/web/src/components/ChatView.logic.test.ts`, `docs/user/composer.md`	Web dispatch planning queues follow-ups during compaction and background waits. Composer submissions, shortcuts, and send controls use that state to determine queueing and steering. Tests cover queue planning, local-dispatch holds, and send-control busy states. The guide describes follow-ups during compaction and awaited background work.
Server queue admission and resumption `apps/server/src/orchestration-v2/Orchestrator.ts`, `apps/server/src/orchestration-v2/runtimeLayer.test.ts`, `docs/user/thread-sidebar.md`	Server orchestration holds queued messages while completion-holding background work or a usage-limited run blocks them. Tests cover background-task queueing and continuation behavior. Sidebar guidance describes queued messages and scheduled continuations.

Derive pending tasks for the detail fallback.

When the mobile shell is unavailable, threadDetailToShell leaves pending tasks empty. If background work holds completion, a follow-up can be sent with start_immediately instead of queued. Derive the pending tasks from the thread detail in this fallback.

Fixed in 9d0acf4. threadDetailToShell now derives pendingBackgroundTasks from the projection, so Queue still sees awaited background work when the shell stream is missing.

Disable Compact while awaited background work is pending.

compactThreadUnavailable reads isWorking, and isWorking no longer includes isWaitingOnBackgroundWork. While the runtime is idle and background work is pending, Compact stays enabled. Its standalone /compact send carries no queue mode. The server path that is inspected does not hold a start_immediately turn, so the compaction can start while the awaited work is still pending. Before this change, that wait disabled Compact through isWorking.

Note

🤖 Composer responding on behalf of wSedlacek

Fixed in f10a1cfe94. compactThreadUnavailable now includes isWaitingOnBackgroundWork, so Compact stays disabled while awaited background work holds even though that wait remains out of isWorking for the Waiting banner.

Expose an explicit Queue action after a usage-limit stop
When the thread is idle after a usage-limit stop, mobile offers no Queue choice. A normal submission can start immediately instead of waiting for continuation.
Expose Queue alongside the default Send action, and carry an explicit queue override through to the outbox even when activeThreadBusy is false. Keep Send immediate.

Expose Queue after a usage-limit stop.
When a limit stops the thread and no work is active, the web composer sends auto even with the alternate modifier. Users cannot queue a new follow-up for after continuation. Expose an explicit Queue action for this state, including its keyboard path, while keeping ordinary Send immediate.

Hold queued follow-ups during background work
When a run is completed but still has completion-holding background work, queue_after_active can start the follow-up immediately. The follow-up can run before the awaited work finishes.
Apply the background hold to dispatch and queue promotion. Resume the queue when the hold clears, while preserving background completion wakes.

Keep background work visible when a run is queued
When a runtime-mode ceiling blocks a queued follow-up, the completed run can still have awaited background work. The fallback selects the queued run and hides Waiting and Stop. Use the latest executed run for the roster when the latest run is queued.

Test automatic promotion after the continuation.
The explicit resumeQueuedRuns call can mask a regression in automatic promotion. Remove that call and await the follow-up’s starting event before asserting its status.

Merged main (`4580080303`)

merged main (d2c25950b4) with a merge commit to clear conflicts with #24138, which lets providers steer during automatic compaction.

kept main's provider-aware canSteer and this pr's hold: steer is allowed only when canSteer and no awaited background work is pending, in web (ChatComposer, composerCommandKey) and mobile (use-thread-composer-state).
reworded the composer doc line so it no longer says every compaction blocks steer.

vp run check:changed against main passed through blacksmith-check: format, lint, knip, graphql, typecheck (35 packages), 10 test files, react compiler. the merge resolution was not re-run in a live app; the runtime verification below is from 917bfe4f66 by gpt-6.1-sol.

Verified in a real dev environment

verified the updated head 917bfe4f66c52b9f3385e9d704a3a3beb56d8526 on a linux boat vm, using the real web client, repository Playwright, /usr/bin/google-chrome, and real Codex gpt-6.1-sol turns. projects, threads, and subagents were created through the app. no mocks, fixtures, or replay data.

reproduced on github/main (7171fdd771): with an async subagent still running and the parent showing waiting, ctrl+enter submitted a follow-up as start_immediately. it began another provider turn and hid waiting. the original pr head sent queue_after_active, but the server still started that message immediately.

fixed dispatch and queue promotion to hold ordinary follow-ups behind completion-holding background work. automatic completion notifications keep their wake path. also preserved background tasks when a queued run becomes the latest run, keeping waiting and stop visible.

the hosted server-shard check caught a regression where a stopped cohort still held unrelated work. fixed the hold to exclude disposed subagents. the entire delegated-completion suite now passes, with 184 tests across that suite, runtime queueing, and background-work derivation. repeated real Codex background queueing and compaction after this correction.

verified after the fix:

ctrl+enter and the queue button both queue messages during background waits. a second message also queues, with no stuck send spinner.
waiting and stop stay visible, steer is unavailable, and compact is unavailable. queued messages survive a browser reload.
both queued messages run automatically after the real child finishes. its completion notification also reaches the parent.
a follow-up queues during real Codex /compact and runs after compaction completes. this compaction path also worked in the main comparison.
stop cancels a running child and holds its queued follow-up. resume then runs that follow-up successfully.

Not verified

an actual provider usage-limit stop, scheduled reset, and resume-after-limit ordering: this account did not hit a real usage limit. the existing server test passed, but that is not live provider proof.
native ios/android and desktop shells, other providers, remote relay/tunnel connections, and native awaited-command behavior. the real background-work check used app-owned Codex subagents; explicit t3_background_wait is unsupported on this provider path.
full ci suites and release builds. the remote scoped checks passed; current hosted check status is separate from this runtime verification.
