fix(web,mobile): held queues show a Queue held state with Resume#21164

GitHub fork: fix/queue-held-visibility

View on GitHubTwo-way sync enabledPR last imported 15d ago

Held automatic queues lacked a visible held-state indicator on web, and mobile hid the queue entry when no user messages were waiting. Web now shows Queue held and Resume queue even with zero visible messages. Mobile keeps its queue entry and sheet available in the same state. Automatic message contents stay hidden.

Resume uses the existing command, checks operate permission, and prevents duplicate pending requests. t3_queue_list also reports each run's existing queueHeld value. The takeover removes the extra automatic-delivery count and fixes the mobile entry-point gate.

Thanks @matthias-scale for the original fix in #21164. Original commits are preserved, with current main merged and maintainer changes added on top.

Verification:

Focused tests: 23 → 23 across the same three files: browser queue control 4 → 5, queue workflow 17 → 16, MCP integration 2 → 2. The held-only browser regression fails when the fix is removed. MCP pagination verifies the additive field without changing the existing stop scenario; one existing command-rejection test also passes.
Web, mobile, server, and client-runtime typechecks pass. Changed-file lint and format pass.
Integrated Linux Chromium confirms the actual app has isHeld: true and zero visible queue rows while displaying Queue held and Resume queue, at desktop and narrow viewports. Resume dispatch, pending state and permission behavior are covered by the browser component test; the synthetic integrated fixture was not resumed into a provider run.
Native device access is disabled in this environment. iOS/Android entry reachability, sheet navigation and Resume need human verification. macOS, Windows, Electron desktop, remote/relay and tunnel sessions were not exercised. This PR is not ready to merge until the missing native proof is supplied.

Queues held by a usage-limit error must first continue through the existing composer recovery action; the queue button alone returns the server’s existing recovery error.

Before (main component, held automatic-only fixture, 1280 × 800):

Before: no held queue indicator

After (same fixture and viewport):

After: Queue held and Resume queue remain visible

Three parallel adversarial review rounds completed. The first found a test-path regression; the original plain-stop scenario was restored. CI then caught React Compiler bailouts in both Resume handlers: try/finally without catch is unsupported. The handlers now use the existing Promise .finally() pattern, preserving cleanup on every command result. Both selected compiler coverage cases, the five browser tests, scoped web/mobile types, lint and format pass. Both reviewers found no code blockers in round three. An unrelated workflow-highlighting browser test passed all three focused cases on retry; CI passes on the published correction 91b99f9, including the full web and package test jobs.

Implemented through T3 Code with Codex gpt-6.1-sol; tests by Codex gpt-6-astra; independent adversarial reviews by Claude claude-opus-5-5 and Codex gpt-6-sol.

Approvability

Verdict: Approved at fa4537e

Macroscope's review found this PR approvable — This is a localized visibility fix for already-supported held-queue and resume behavior across web, mobile, and the read-only MCP listing. Existing processing semantics remain unchanged, and the API adjustment is additive.

📝 Walkthrough

The mobile and web queue controls now show held state, including when no visible queued items remain. The web control offers queue resumption and reports held automatic wake-ups. MCP queue-list items now include a queueHeld boolean.

Changes: Held queue controls

Layer / File(s)	Summary
Held queue state and controls `packages/client-runtime/src/state/threadWorkflows.test.ts`, `apps/web/src/components/chat/QueuedRunsControl.tsx`, `apps/mobile/src/features/threads/ThreadQueueControl.tsx`	The test covers a held monitor notification that does not appear in visible queued runs. The web control counts held automatic wake-ups, displays the held banner when the queue is empty or populated, and offers a resume action. The mobile control stays open while the workflow is held, displays the held banner, and labels it “Queue held.”

MCP queue reporting

Layer / File(s)	Summary
MCP queue-held metadata `apps/server/src/mcp/toolkits/thread/tools.ts`, `apps/server/src/mcp/toolkits/thread/handlers.ts`, `apps/server/src/mcp/OrchestratorMcpToolkit.integration.test.ts`	The `t3_queue_list` schema and handler include a `queueHeld` boolean for each item. Integration expectations check the field on both pages.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix · Severity of issue fixed: Low

Suggested reviewers: juliusmarminge

Merge Risk: ⚪ Minimal · up to e3c00

The held-queue display change appears ready to merge after normal checks.

Security architecture risk: 🔵 Low · up to fa453

The change primarily improves visibility. The new Resume action uses the existing queue command, and server-side permission checks remain authoritative. No introduced security vulnerability was established, though assurance is limited by incomplete security and recovery-path coverage.

Retained concerns No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The added action operates on the selected thread's existing queue, including held automatic runs, under existing execution authority. MCP callers gain status metadata for queues already reachable through the existing thread-read mechanism, not a new mutation capability.

Trust Boundaries and Controls

observed — The new web caller uses generic command dispatch rather than the composer's orchestration-scope preflight. This changes client-side rejection behavior, but the RPC group applies authorization middleware using authenticated session scopes, and command dispatch requires orchestration-operate scope. An unauthorized queue mutation was not established.

Cover the held case in t3_queue_list.
The integration test checks only queueHeld: false. The handler maps held queued runs to queueHeld: true, but this MCP path has no true-case assertion. Add a held queued run, invoke t3_queue_list, and assert queueHeld: true. Existing stop tests show that run.interrupt with holdQueue: true creates this state.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Mobile sheet closes before the user can resume a held queue with no visible runs.

The new held banner can now appear when queuedRuns is empty. The effect at Lines 103-109 calls navigation.goBack() only if hadQueuedRuns.current was true. If the sheet opens with only held automatic runs, the banner stays visible. If the last visible run is removed while the queue is still held, the sheet closes and the user cannot reach "Resume queue" from here.

Keep the sheet open while workflow?.isHeld is true.

Proposed fix

2	- }, [navigation, queuedRuns.length]);
3	+ if (hadQueuedRuns.current && workflow?.isHeld !== true) navigation.goBack();
4	+ }, [navigation, queuedRuns.length, workflow?.isHeld]);

Also, the "No messages waiting in this queue." text at Line 216 shows together with the held banner. Confirm that this is the intended wording for the held-automatic-only case.

✅ Addressed in commit e3c00f1

Mmatthias-scale23d ago

Fixed in e3c00f1676: the sheet stays open while the queue is held, and the "No messages waiting in this queue." line is hidden while held, so the held banner stands alone in the held-automatic-only case.

CcoderabbitaiBot23d ago

@matthias-scale Thanks for the fix. The supplied code keeps the sheet open while the queue is held and hides the empty-state text. This addresses both concerns.

Taking over this PR as maintainer for composer-chat-08. I’ll preserve the held-queue visibility improvement, fix the mobile entry when the visible message count is zero, keep the copy aligned with current main, and run focused tests plus independent implementation and adversarial review passes before pushing here.

fix(composer): keep held automatic queues visible and resumableb3f604f

JJulius Marminge22d ago

The takeover keeps the existing MCP plain-stop scenario intact. Adding holdQueue there would remove its coverage of the non-hold interrupt path and change child-stop semantics, so I declined the extra true-case assertion rather than weakening that test. Existing pagination assertions check the additive queueHeld field; the held UI and shared workflow regressions cover automatic-only visibility. The one-line MCP mapping remains run.queueHeld === true.
