fix(mobile): review dictated drafts without opening the keyboard

[Dwite]

Problem

The voice input guide says dictated text is inserted "ready for you to review and edit before sending". When dictation starts from the collapsed thread composer on iPhone, the transcript lands in a one-line field. Most of it cannot be read without tapping the field, which opens the keyboard.

Change

After a transcript lands in a collapsed thread composer, the composer opens to its full-height reading area without focusing the editor, so the keyboard stays down.

• Tapping the text focuses the editor as usual. Tapping the conversation collapses the composer. Sending clears the review state.
• The review state is scoped to the thread and only starts when the composer was not focused. Dictating into an open, focused composer behaves as before.
• The feed inset and the safe-area padding follow the taller composer, so the last message is not covered.

Two files: ThreadComposer.tsx holds the expanded-unfocused layout, and ThreadDetailScreen.tsx owns the review state and the feed spacing. The new-task composer already uses an expanded editor and is unchanged.

Scope and approval

This is a rebuild of #12917 on orchestrator V2, as asked in the closing comment. There is no prior issue or discussion. I am submitting it under the small, focused fix exception.

• Defect: the documented review step does not work for a collapsed composer, because the transcript is not readable there.
• Why it fits the exception: it reuses the existing expanded composer layout on the existing-thread screen. It adds no setting, default, contract, or provider change.

If you read this as a product behavior change and not a bug fix, tell me and I will take it to an Ideas discussion first.

Verification

Types and tests checked at 480d6dd61, merged with main at d72021099. The simulator captures are from c07523581, before that merge.

Main moved dictation into a shared session that keeps running after the composer leaves the screen (#15502). The transcript now lands through the callback captured when dictation started, so the review callback now reads composer focus from a ref that the focus events write, at the moment the transcript lands. The behavior on the thread screen is meant to be the same as in the captures.

Focused tests and types

• tsc --noEmit passes in apps/mobile.
• vp test run src/features/voice-input src/features/threads in apps/mobile: 348 tests pass in 42 files.
• Lint on the two changed files reports no errors.

iPhone simulator on V2

iPhone 17 Pro simulator, iOS 26.5, dev client built from this branch, connected to an isolated dev server. Simulators have no on-device transcription, so I used a temporary recorder and transcriber fixture that returns a fixed transcript after 1.5 seconds. The fixture was never committed. The before capture runs main's two composer files with the same fixture.

Before: transcript in one line	After: full reading area, keyboard down

Tap the text: editor takes focus	Tap the conversation: composer collapses

Before recording (9 s, 1.5x) · After recording (32 s, 2.5x)

1. Dictation from the collapsed composer: the composer opens to the full reading area, the editor is not focused, and the feed moves up with it.
2. Tap the text: the editor takes focus and the composer returns to its normal focused layout.
3. Tap the conversation: the composer collapses to one line.
4. Dictate again: the review opens again. Tap the conversation: it collapses directly.

One difference from #12917: the review starts only when the composer was not focused when the transcript landed. Dictating into a focused composer no longer leaves it tall after the keyboard is dismissed.

The environment name in the header is redacted in the screenshots and recordings.

Not checked: the simulator after the merge with #15502, a transcript that lands while another screen is in front, real microphone capture and speech recognition, a physical device, and sending from the review state (it would start a real agent run; handleSendMessage clears the review state). In step 2 the simulator had a hardware keyboard connected, so the software keyboard is not in the screenshot. Android is unaffected: voice input is iPhone-only.

Rebuilt from #12917 (GPT-6 in Codex). V2 rebuild and verification: Claude Opus 5.5 in Claude Code.

Approvability

Verdict: Approved at c075235

Macroscope's review found this PR approvable — This is a narrowly scoped mobile UI bug fix that keeps dictated drafts readable without opening the keyboard, while preserving existing focused editing and sending flows. It changes only composer state, sizing, and feed inset handling, with no schema, configuration, or sensitive-area impact.

📝 Walkthrough

Walkthrough

The thread composer keeps a completed dictated draft expanded for review. The thread screen tracks review state for the selected thread and clears it when the composer is focused, collapsed, or the message is sent successfully.

Changes

Dictation Draft Review

Layer / File(s)	Summary
Composer dictation review behavior apps/mobile/src/features/threads/ThreadComposer.tsx	The composer calls a completion callback when dictated text updates the draft. During review, it stays expanded and sets the editor’s minimum height to its maximum height.
Thread review state and layout apps/mobile/src/features/threads/ThreadDetailScreen.tsx	The screen tracks review state for the selected thread when a nonempty draft is unfocused. It adjusts composer chrome and the iOS bottom inset during review, and clears review state on focus, successful send, or collapse.

Merge Risk: 🔵 Low · up to 480d6

Returning to a thread can unexpectedly reopen the review layout for an existing dictated draft. This is a localized UI issue with a small fix; the PR is otherwise mergeable.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 480d6

The change preserves thread-specific drafts and explicit user-controlled sending. No new access or authority was identified. Review presentation can reactivate after returning to a thread, and native interruption behavior has not been verified end to end.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated new exposure is the taller display of an existing draft on its matching thread screen. The inspected flow does not establish new cross-thread writes, background submission or increased service authority.

Trust Boundaries and Controls

• observed — Transcript text remains draft input rather than send authority. Sending remains an explicit action with existing submission gates; review cleanup occurs only after a non-null send result for the originating selected thread. Refused sends preserve review.

Resilience and Maintainability Implications

• observed — The unchanged controller invalidates canceled operations, discards interrupted recordings and checks operation identity after asynchronous transcription. Failure, stale-draft and empty-transcript paths return without committing; terminal cleanup releases resources and deletes owned recording files. These source controls do not verify every native event-delivery scenario.

Clear dictation review when the selected thread changes.

The split-view thread selector updates the existing Thread route with new parameters. The per-thread draft remains in composerDraftsAtom, so returning to the original thread restores its nonempty draft. Because this effect resets focus but keeps dictationReviewThreadKey, the review predicate becomes true again for the old thread.

Suggested fix

    composerFocusedRef.current = false;
    setComposerFocused(false);
+   setDictationReviewThreadKey(null);
  }, [selectedThreadKey, showContent]);
