mobile could accept changes while a queued-message edit was saving, then discard them when the saved draft snapshot was cleared. Overlaps #18846.

derive one submission lock for queued-edit saves and voice input, and apply it to typing, paste, attachments, command suggestions, dictation start, and send in both composer layouts. the model-control region is unchanged.

blacksmith passed the mobile typecheck, targeted lint, and 109 tests across the existing queued-edit, draft, send-presentation, and command-menu suites.

tested end to end on an android 16 emulator against a real t3 backend with real provider turns. before is plain main; after is this pr merged with the other mobile parity prs on the same main. queued edit, save, and execution work end to end, rechecked after merging main's one-row composer (#20812). the screenshot catches the locked composer mid-save. in one throttled run, text injected with adb right after tapping save landed before the lock rendered (about a second on this software-rendered emulator) and was dropped when the save finished; collapsed thumbnails now also respect the lock (5f8ffa2). voice input blocking was not exercised.

Approvability

Verdict: Approved at 5f8ffa2

Macroscope's review found this PR approvable — This is a focused mobile bug fix that unifies the queued-edit save lock with the existing voice-input lock, preventing edits, submissions, and attachment interactions while a draft snapshot is being saved. It is confined to the existing composer and introduces no schema, infrastructure, security, billing, or default-setting changes.

Merge Risk: ⚪ Minimal · up to 5f8ff

While a queued message edit is saving, the mobile composer now blocks typing, pasting, attachment changes, command suggestions, starting dictation, and sending, so edits are no longer lost when the save completes. Stopping or cancelling an active dictation still works. No outstanding defects were found, and the change is ready to merge.

Note

Grok responding on behalf of Julius.

#18846 just landed on main and covers the direct-typing half of this: the native text editor now goes read-only while queuedEdit.saving is true. This PR still covers more than that (attachment buttons and strip, paste, command suggestions, dictation start, and the send guard), and #18846 explicitly left those out of scope, so I'm leaving this open. Could you merge main and narrow it to the remaining lock surfaces? The readOnly line in ThreadComposer.tsx will conflict with what landed.

apps/mobile/src/features/threads/ThreadComposer.tsx:1045-1057
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Guard collapsed thumbnail callbacks while submission is locked.

When the composer is collapsed, ThreadComposer passes onPressPreview and onPressVideo directly to each thumbnail. A user can therefore tap an image, PDF, or video while a queued edit is saving or voice input blocks submission, and open its preview.

Pass undefined while locked. The thumbnail component already disables its press action when these callbacks are absent.

Suggested fix

-                    onPressVideo={onPressVideo}

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Gate attachment-upload retry on isSubmissionLocked.

ComposerAttachmentThumbnail keeps the retry button enabled for failed uploads. A locked composer can therefore clear the failed state and start uploadQueue.retry(...). A successful retry can update the draft attachment reference and flush the draft while queued-edit saving or voice-blocked submission is active.

Propagate the lock to both ComposerAttachmentStrip and the collapsed thumbnail, and use it to disable retry.

apps/mobile/src/features/threads/ThreadComposer.tsx:909-929
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Disable context-chip document opening while the composer is locked.

When isSubmissionLocked is true, ComposerEditor still invokes onOpenAttachment for a document context chip. ThreadComposer always supplies openDraftDocument, so an expanded locked composer can open the document even though other attachment actions are disabled.

Pass a no-op callback while locked, consistent with the other locked attachment callbacks.

Suggested fix

-                onOpenAttachment={openDraftDocument}
+                onOpenAttachment={
+                  isSubmissionLocked ? undefined : openDraftDocument

re the three outside-diff notes on ThreadComposer.tsx:

• collapsed thumbnails: fixed in 5f8ffa2; they now drop their preview handlers while the composer is locked, matching the expanded strip.
• upload retry and context-chip document opening: leaving these. neither changes the draft text or attachment list that the save snapshots, main does not gate them during voice input either, and gating retry would mean threading a new lock prop through ComposerAttachmentStrip.
