The React Compiler skipped the new task flow, the thread settings and git sheets, the work log, and the composer command menu.

Frozen-clock fix in UsageLimitRecoveryCard. The snooze button's disabled read Date.now() during render. Compiled, it would be cached on resetAt and stay enabled after the reset passes. It is now state, flipped by a timer at resetAt.

Manual useMemo/useCallback/memo are removed from every file listed. KNOWN_BAILOUTS: 34 → 22.

Verified on device (Pixel 9 API 36 emulator, isolated seeded server):

  • Thread: opened a seeded thread, expanded "Worked for 4m 19s", then expanded a tool group.
  • Git controls sheet opened from the thread menu (branch, PR link, actions).
  • New thread:
    • Switched project via the picker and environment via its picker.
    • Typed /; the command menu listed commands and skills, filtered on mo, and selecting inserted /model.
    • Opened Thread settings from the model chip, starred a model (saved) and unstarred it.
  • No red box, and no useMemoCache or React errors in the Metro log.
  • Not exercised: question attachments, share import, and the usage-limit card, which need a pending question, a share intent, or a usage-limited run.

Renders (measure-renders --route, median of 3, same base and device):

No measurable change; both are within run-to-run spread.

Review follow-up

  • New task: the outbox write, image paste, pasted-text attachment and question attachments use settlePromise. Branch checkout, scratch start, machine switch, git refresh, favorites and usage-limit recovery await commands directly.
  • Fixes a regression this layer introduced: the return inside the outbox .catch no longer exited submit, so a failed write still cleared the draft. It now returns early again.
  • latestDraftKeyRef/latestIncomingShareIdRef became one useEffectEvent (isCurrentShareImport) for the share import effect. A narrower latestDraftKeyRef layout-effect sync stays for the pasted-text handler, because an event handler can't call an effect event and the provider's draft key lives in React state, not a store. The reason is commented in the code.
  • useThreadSettingsCatalogItems called no hooks once its useMemo was gone, so the compiler skipped it and rebuilt the model catalog every render. It is now a plain buildThreadSettingsCatalogItems(session), called after the component's last hook so the compiled component caches it on session. I checked the compiled output.
  • Not exercised on device.

Device: Pixel 9 API 36 emulator on nucbox-1, client rebuilt from perf/mobile-compile-8 (the old one lacked the T3FoldPosture native view), Metro and an isolated seeded server on cups.

🔴 Critical threads/NewTaskDraftScreen.tsx:1278

When enqueueThreadOutboxMessage rejects, handleStart still clears the composer draft, schedules attachment cleanup, and navigates away, losing the unsent task instead of leaving it available for retry. The return inside .catch() only exits that callback; return from an outer catch before the draft-clearing logic.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This is an XXL production-mobile refactor spanning shared task-flow state, settings, Git actions, attachments, usage recovery, rendering, and compiler integration, with several non-mechanical async and lifecycle changes. The breadth of runtime impact and the unresolved reset-timer risk warrant human review.

📝 Walkthrough

The change removes React memoization across mobile thread task flows, Git controls, settings, work-log rendering, and composer actions. It also updates incoming-share tracking, async result handling, and usage-reset timing. The compiler coverage test removes 12 files from its known-bailout list.

Changes: Mobile thread updates

Layer / File(s)Summary
Task-flow provider state and context
apps/mobile/src/features/threads/new-task-flow-provider.tsx
The provider computes derived values and handlers during render and creates its context value directly. Environment switching clears state after resolved requests, but not after a rejected scratch-open request.
Task screens and draft operations
apps/mobile/src/features/threads/NewTaskContextPickerScreens.tsx, apps/mobile/src/features/threads/NewTaskDraftScreen.tsx, apps/mobile/src/features/threads/NewTaskRouteScreen.tsx
Task screens recreate handlers directly. Incoming-share tracking uses state and an effect event. Paste and queue operations use settled results. Branch and scratch flows use explicit cleanup paths.
Git controls and thread settings
apps/mobile/src/features/threads/ThreadGitControls.tsx, apps/mobile/src/features/threads/git/GitCommitSheet.tsx, apps/mobile/src/features/threads/git/GitOverviewSheet.tsx, apps/mobile/src/features/threads/ThreadSettingsSheet.tsx
Git handlers, menu items, settings values, and model catalog data are created directly instead of being memoized. Refresh and favorite cleanup use explicit success paths.
Work-log and composer rendering
apps/mobile/src/features/threads/thread-work-log.tsx, apps/mobile/src/features/threads/use-composer-command-menu.ts
Work-log functions and shared values, plus composer command-menu values and handlers, are recreated during render. Existing scroll, selection, and command behavior remains.
Attachment and usage-limit state
apps/mobile/src/features/threads/QuestionAttachments.tsx, apps/mobile/src/features/threads/UsageLimitRecoveryCard.tsx, apps/mobile/src/reactCompilerCoverage.test.ts
Attachment-picker results use settled-result handling. Usage-limit recovery tracks reset time with an effect and timer. The coverage test removes 12 files from its known-bailout list.

For a distant usage-limit reset, the snooze button could remain enabled after the reset. This is a narrow issue suitable for a localized fix.

Stop handleStart when the outbox enqueue fails.

The return at Line 1286 exits only the .catch() callback. It does not exit handleStart. The rejection is handled, so the awaited chain resolves. Execution then continues to Line 1291 and later lines:

  • flow.finishEditingPendingTask() clears the pending-task draft and releases the drain lock. Otherwise, clearComposerDraftContent clears the new-task draft.
  • setSubmitNavigationAction navigates to the Thread route or goes back.
  • scheduleUnusedComposerAttachmentCleanup removes the draft attachments.

Here is the trigger. enqueue in apps/mobile/src/state/thread-outbox-manager.ts (Lines 107-138) rolls the message out of the queue and throws ThreadOutboxManagerError when the storage write fails, for example on a full disk. The test "rolls an enqueued message back out when the durable write fails" (apps/mobile/src/state/thread-outbox.test.ts, Lines 692-720) confirms this behavior. After this failure, the message is not in the outbox, and this code still deletes the draft and its attachment files. The user sees "Could not queue task" and then loses the prompt and attachments. A new task also navigates to a thread that does not exist.

The previous try/catch/finally returned from handleStart in the catch block. Keep that behavior with an explicit success flag.

apps/mobile/src/features/threads/UsageLimitRecoveryCard.tsx:40-41 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Schedule a follow-up timer for distant resets.

If resetAt is more than 2,147,483,647 ms away, this effect schedules no timer. A later render with the same resetAtMs does not rerun the effect. The snooze button can therefore remain enabled after the reset passes. Schedule a timer for the maximum supported delay, then check and reschedule until resetAt passes.
