Problem

Mobile's queued-message edit only noticed that its run had started while that thread's composer was mounted. If you left the thread, the edit stayed open, and the keep-or-discard decision happened whenever you came back. The thread settings sheet also pushed a new session object into a context at the Stack root on every composer render while it was open, which re-rendered the workspace tree each time.

Change

  • Queued edits now use the shared @t3tools/client-runtime/queued-run-edit store, which web already uses. beginQueuedRunEdit takes the thread's runs atom and ends the edit as soon as its run leaves the queue. A changed edit goes back into an empty thread draft; otherwise it is discarded. Either way the thread gets a composer error message. A save in flight claims the edit with startSave, so the save's result decides what happens to it.
  • Settings sheet: the ThreadSettingsSheet route takes { environmentId, threadId, draftKey } params and reads the thread, draft settings and prompt itself. ExistingThreadSettingsRouteProvider and its context are gone, along with the composer's two effects that fed it. The sheet hook gets explicit onPresent, onEditorFocusChange and dispose inputs instead of mirroring focus into a ref through an effect. The existing-thread sheet reads the quiet thread structure (environmentThreadDetails.quietThreadAtom) for threadAllowsProviderSwitch, so streamed text does not re-render the model picker. The draft (new task) composer pushes NewTaskThreadSettings, its flow's own route. The now-unused onUpdateModelSelection/onUpdateRuntimeMode props are removed from ThreadDetailScreen, ThreadRouteScreen and NewTaskDraftScreen.
  • Acknowledged messages: render hides rows the projection already holds (selectPendingAcknowledgedMessages). Writes prune rows echoed in an already-mounted thread, so the list stays small without a pruning effect. The outbox drain tests' ./threads mocks gain environmentThreadDetails for that read.
  • Image previews: data-URL materialization moved to materializedPreviewAtom, an Atom.family keyed by attachment id. ComposerAttachmentStrip now compiles under the React Compiler, so it is removed from KNOWN_BAILOUTS and its manual useMemos are dropped.
  • Queue drag: a queue that changes under a drag hides the drag preview, derived in render, instead of resetting it in an effect.
  • Reanimated: the composer border radius and the dictation flip/visibility animations use useDerivedValue/useAnimatedStyle with withTiming instead of layout effects that write shared values.
  • QuestionAttachments is keyed by request and question, so its picker scope is simply the component's lifetime.

What this improves

  • Bug: a queued edit ends when its run starts, even when that thread isn't open. Test: queued-run-edit.test.ts > beginQueuedRunEdit > ends a changed edit when its run starts, without the thread's composer mounted. It fails with main's queued-run-edit.ts.
  • Renders avoided: the Stack-root settings context no longer updates on every composer render while the sheet is open. ComposerAttachmentStrip is now compiler-memoized.
  • Sync removed: acknowledged-message pruning, the queued-edit exit, settings route session pushing, sheet focus mirroring, queue drag reset, and preview materialization state.

Behavior changes

  • When an edit's run leaves the queue with the edit unchanged, it now closes silently. Before, an unchanged non-empty edit was copied back into an empty thread composer with "Your edit is back in the composer." (or reported as discarded when the composer had text). A changed edit still shows the kept/discarded message. An edit with only new attachments now counts as changed.
  • Deleting the thread ends its open queued edit (via the shared store's makeQueuedRunsAtom).
  • The new-task composer's settings button opens NewTaskThreadSettings instead of ThreadSettingsSheet with a session built from the flow. Model selection there goes through flow.setSelectedModelKey(option.key, …) and flow.setSelectedModelOptions, as it already did when that route was opened from the new-task screen.
  • When a saved inline image preview can't be cached, it still logs the same console.warn, now from the atom.
  • Removing a server attachment from a queued edit now counts as a change, so if the run starts before you save, the thread shows the kept/discarded message instead of closing the edit silently.
  • Clearing all text from a queued edit counts as a change. If the run starts before you save, the thread shows "That message already started, so the edit was discarded." A cleared edit has nothing to restore, so it is never moved into the composer.
  • If the thread settings sheet is open on a queued edit when that edit ends, the sheet edits the thread's own draft from then on.
  • If a queued-edit save fails after its run has already left the queue, the "Your edit is still in the composer" alert no longer appears. The composer's kept/discarded message describes what actually happened.
  • Image previews are written to a .partial file and moved into place only after the write succeeds, so a failed write is never reused as a blank cached preview.

Effects

ComposerAttachmentStrip 2 -> 0, ThreadComposer 6 -> 4, ThreadQueueControl 2 -> 1, ThreadSettingsSheet 2 -> 1, use-thread-settings-sheet-presentation 2 -> 0, ComposerDictationControl 3 -> 0, use-thread-composer-state 3 -> 0 (20 -> 6).

Kept on purpose: the model-preferences migration effect in ThreadSettingsSheet, and the composer's unmount cleanups. The sheet dispose runs from an empty-deps effect through useEffectEvent, so it can never fire mid-life. ComposerPopoverAnchor.android keeps its unmount effect: moving it into an inline ref callback would rely on compiler memoization to avoid running every render.

Verification

  • vp test run on composerImagePreview, pending-thread-feed, thread-task-permissions, reactCompilerCoverage and queued-run-edit: pass. The new queued-run-edit test fails against main's module.
  • vp test run src/state src/features/threads src/components src/lib in apps/mobile: 113 files, 1132 tests pass.
  • vp run check:changed: format, lint, knip, typecheck (2 packages) and tests (8 files) all pass.
  • Review follow-up: four new or updated tests (queued-run-edit.test.ts, composerImagePreview.test.ts, client-runtime queuedRunEdit.test.ts) fail with the fixes reverted. vp run check:changed passes after rebasing on main.
  • Cleared-edit follow-up: a new test, queued-run-edit.test.ts > beginQueuedRunEdit > reports a cleared edit as discarded when the run starts, fails without the fix.
  • iOS 27.0 simulator (iPhone 17 Pro) against an isolated backend with Codex. A queued edit cleared to nothing showed the discarded message when its run started, and the composer stayed empty. A normal edit saved and ran the new text. Sending while a turn ran and switching threads both worked.

🟡 Medium state/use-thread-composer-state.ts:487

When editQueuedRun fails after the run leaves the queue, finishSave(false) resumes the exit watcher, which can discard the edit because the normal thread draft is occupied. This branch still says “Your edit is still in the composer,” so the user is told discarded work remains available; check whether the edit survived before showing that message.

3When `editQueuedRun` fails after the run leaves the queue, `finishSave(false)` resumes the exit watcher, which can discard the edit because the normal thread draft is occupied. This branch still says “Your edit is still in the composer,” so the user is told discarded work remains available; check whether the edit survived before showing that message.

Fixed in afd5cc0b08. On failure, FinishQueuedRunEditSave now returns whether the edit is still open after its exit watch resumes. The hook skips the "still in the composer" alert when it returns false: the exit has already set the composer message (kept or discarded). The store test now asserts false when the run left the queue during the save, and a new test asserts true while the run is still queued. Web ignores the failure return, so it is unaffected.

I can’t verify this yet: afd5cc0b08 is not present on the PR head available to me, which still has the original behavior. Please push/update the ref and I’ll re-check.

🟡 Medium state/queued-run-edit.ts:62

Removing an existing attachment and then having the run leave the queue before save silently discards the edit: editChanged checks only text and draft uploads, so the removal from edit.existingAttachments is classified as clean and no composer error is shown. Include removals from the original attachment set (or an explicit dirty flag) in the change check so the edit takes the recovery path.

Fixed in afd5cc0b08. removeQueuedRunEditAttachment now marks the edit removedExistingAttachment, and exitQueuedRunEdit counts that as a change. The edit then goes through the kept/discarded path and the thread shows the message. Test: "treats a removed server attachment as a change when the run starts".

I can’t find afd5cc0b08 on the current PR head; it still only filters existingAttachments and exitQueuedRunEdit does not consider removals. Could you push the referenced commit to this PR?

Fixed in afd5cc0b08. The sheet now resolves its draft with activeComposerDraftKey: it uses the queued edit's draft only while that edit is still open, and the thread's own draft after that. Both the prompt it reads and onPromptChange use the resolved key. Covered in queued-run-edit.test.ts (activeComposerDraftKey).

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This is a broad mobile runtime change across 27 files, adding app-wide queued-edit watchers and draft recovery/discard behavior while also rewiring settings navigation and other state, preview, and UI lifecycles. The tests are helpful, but the cross-cutting runtime and navigation impact warrants human review.

Walkthrough

The PR updates mobile thread settings routing, queued-run edit handling, pending-message filtering, attachment preview materialization, picker lifetimes, and derived composer animations.

Changes: Thread settings and composer configuration

Layer / File(s)Summary
Route-based thread settings
apps/mobile/src/Stack.tsx, apps/mobile/src/features/threads/ThreadSettingsSheet.tsx, apps/mobile/src/state/use-thread-detail.ts, apps/mobile/src/state/thread-provider-switching.ts
Existing-thread settings now use typed route parameters and draft-backed state. The route derives thread, model, runtime, and provider-switching values from current state.
Composer settings callback contract
apps/mobile/src/features/threads/ThreadComposer.tsx, apps/mobile/src/features/threads/ThreadDetailScreen.tsx, apps/mobile/src/features/threads/ThreadRouteScreen.tsx, apps/mobile/src/features/threads/NewTaskDraftScreen.tsx, apps/mobile/src/state/use-thread-composer-state.ts
Model-selection and runtime-mode callbacks are removed from thread composer wiring. Draft model selection is updated through an exported helper.
Settings presentation lifecycle
apps/mobile/src/features/threads/use-thread-settings-sheet-presentation.ts, apps/mobile/src/features/threads/ThreadComposer.tsx
Settings presentation tracks editor focus through refs, cancels stale work, and exposes disposal. The composer reports focus and route-dismissal events.

Pending messages and queued-run edits

Layer / File(s)Summary
Acknowledged-message filtering
apps/mobile/src/features/threads/pending-thread-feed.ts, apps/mobile/src/features/threads/pending-thread-feed.test.ts, apps/mobile/src/state/acknowledged-thread-messages.ts, apps/mobile/src/state/use-thread-composer-state.ts
Acknowledged messages already queued or projected are excluded. Mounted thread projections are removed from acknowledged-message state.
Queued-run edit lifecycle and save state
apps/mobile/src/state/queued-run-edit.ts, apps/mobile/src/state/use-thread-composer-state.ts, packages/client-runtime/src/queuedRunEdit.ts, apps/mobile/src/state/queued-run-edit.test.ts, packages/client-runtime/src/queuedRunEdit.test.ts
Queued-run edits track run exits, draft restoration, attachment removal, and save validity. Tests cover failed saves, discarded edits, and active draft selection.
Queue drag consistency
apps/mobile/src/features/threads/ThreadQueueControl.tsx
Drag state captures queue order and hides previews or rejects updates when that order is stale.

Composer attachments and animations

Layer / File(s)Summary
Cached image preview materialization
apps/mobile/src/lib/composerImagePreview.ts, apps/mobile/src/lib/composerImagePreview.test.ts, apps/mobile/src/components/ComposerAttachmentStrip.tsx, apps/mobile/src/reactCompilerCoverage.test.ts
Data-URL previews are materialized in the cache and reused by attachment ID. The attachment strip reads the materialized preview atom and resolves file-backed URIs.
Question attachment picker lifetime
apps/mobile/src/features/threads/PendingUserInputCard.tsx, apps/mobile/src/features/threads/QuestionAttachments.tsx
Question attachment instances are keyed by request and question IDs. Paste and picker results are accepted only while the instance is active.
Prop-derived composer animations
apps/mobile/src/features/threads/ThreadComposer.tsx, apps/mobile/src/features/voice-input/ComposerDictationControl.tsx
Composer and dictation animations derive values from current props or state instead of synchronizing shared values in layout effects.

Merge Risk: External image Low · up to 6b0b1

An over-limit queued edit could report that its attachments were restored when some were skipped. This is a bounded risk that should be addressed or explicitly accepted; the previously reported preview-write and cleared-text failures are fixed.

Handle the kept-path persistence result.

mergeComposerDraftContent returns the persistence promise and { skippedAttachmentCount }. The current void call can expose write failures as unhandled rejections and always reports full recovery.

Partly applied in afd5cc0b08. The merge's promise now has a .catch that logs, so a failed write is no longer an unhandled rejection. I did not add the suggested messages. mergeComposerDraftContent publishes the merged draft to the atom before it awaits the disk write, so the edit really is back in the composer and the next draft write persists it; "could not be saved" would be wrong. skippedAttachmentCount is always 0 here: the kept path runs only when the thread draft is empty, and the edit draft's attachments are already within the attachment limit.

@juliusmarminge Your explanation supports keeping the existing recovery message. mergeComposerDraftContent publishes the merged draft before awaiting the disk write. With an empty destination draft and attachments already within the limit, the merge does not skip attachments. My suggested messages were unnecessary.

I could not verify the logging .catch: the inspected checkout still has the bare void call, and commit afd5cc0b08 is unavailable there. Please retry verification once that commit is available. The only remaining check is the rejection handler.

Do not treat an incomplete preview file as cached.

If file.write fails after file.create, the file can remain empty or partial. A later call sees file.exists and returns that file without writing the image. The attachment can then show a blank thumbnail even after the write failure ends. Remove the file when writing fails, and check cached content before reusing an existing file. Expo documents file creation, writing, and existence as separate operations. (docs.expo.dev)

Fixed in afd5cc0b08. The preview is now written to <id>.<ext>.partial and moved into place only after the write succeeds. A failed write deletes the partial file, and a stale partial is replaced, so the cached name exists only for a complete write. Test: "writes the preview again after a failed write instead of reusing the partial file".

Use a collision-free key for each question attachment scope.

React can reuse the existing QuestionAttachments instance across that change. Its active scope and captured draft key then allow an in-flight picker or paste result to append to the previous draft.

apps/mobile/src/state/queued-run-edit.ts:55-73 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve server-attachment changes when recovering a queued edit.

removeQueuedRunEditAttachment changes only edit.existingAttachments, but exitQueuedRunEdit computes editChanged only from the composer draft. Removing the only existing attachment therefore returns "clean" and silently discards the edit. If the text also changes, recovery merges only editDraft.attachments, so the remaining existing attachments are missing from the restored thread draft.

A fix limited to editChanged and the merge in this function cannot distinguish an untouched edit that started with no attachments from an edit whose only attachment was removed. Store an immutable original attachment baseline or an explicit attachment-change marker when the edit begins. Then compare that state during exit and merge the current existing attachments with the draft attachments during recovery.

Report an edit when the user clears all queued text.

If the user deletes originalText and the run starts before a save, this condition makes editChanged false. The edit closes silently, even though the user changed it. Compare the draft with originalText without requiring nonempty content. If the cleared draft has nothing to restore, report it as discarded rather than saying it is back in the composer.

✅ Confirmed as addressed by @juliusmarminge

Fixed in 6b0b1ddb14. A cleared edit now counts as changed, because the draft differs from originalText. A cleared draft has nothing to restore, so it always resolves to discarded. The thread then shows "That message already started, so the edit was discarded." and the empty edit is not moved into the composer. The new test "reports a cleared edit as discarded when the run starts" in apps/mobile/src/state/queued-run-edit.test.ts failed before this fix (no error was reported) and passes now.

@juliusmarminge The supplied code addresses this finding. Clearing the text now counts as a change, and editRestorable prevents the empty edit from returning to the composer. The discarded-edit message covers this case.

✅ Review thread resolved.

Add a test for the kept recovery path.

The new tests cover only the discarded outcome. A changed edit over a non-empty thread draft, a cleared edit, and a removed server attachment over a non-empty thread draft all end in "discarded." No test drives a changed edit into an empty thread draft, so the path that restores user text has no coverage. A regression there would drop the edit text without a failing test.

mergeComposerDraftContent is async. When loadPromise is set, it awaits that promise before it publishes the draft. The test must wait for the thread draft, not assert it synchronously. The error message is set synchronously, so the test can assert it after the wait.
