Companion PR for automated review bots only. Mirrors kahme247#109 (same head, base pinned to upstream/main so the diff is identical).

  • feat(dictation): recording deck with timer, waveform, pause, retry and send modes
  • fix(dictation): remove stray pulse ring and let waveform shrink on narrow composers
  • test(systemd): scrub ambient OMP_WEB_OMP_BIN so install test is hermetic
  • feat(dictation): mic becomes cancel while recording, composer Send transcribes+queues, deck keeps only pause and stop
  • fix(dictation): apply review findings — theme tokens, audio lifecycle, attachment staleness, dynamic waveform width

Summary by CodeRabbit

  • New Features

    • Added voice dictation pause/resume controls, live waveform feedback, recording timers, transcription status, and retry support.
    • Users can preview recordings before transcribing, discard them, or transcribe and send them immediately.
    • Added clearer handling for timeouts, errors, missing speech, and permission issues.
    • Added localized dictation controls and status messages in English, Japanese, and Simplified Chinese.
    • Added an animated transcription progress indicator with reduced-motion support.
  • Bug Fixes

    • Prevented inherited environment settings from affecting installation results.

…anscribes+queues, deck keeps only pause and stop
…, attachment staleness, dynamic waveform width

- Use the theme's --status-error token instead of undefined --danger
  custom properties so dictation colors follow light/dark themes.
- Close the AudioContext and release the analyser when capture finishes,
  not only on cleanup, so transcription no longer holds the mic graph.
- Read attachments through refs inside handleSend/sendQueued so files
  attached mid-recording are included when the transcript dispatches.
- Surface 'No speech detected' when a capture yields no audio instead of
  failing silently.
- Stretch the waveform canvas to the free composer width (dynamic bar
  count, newest samples at the buttons) and freeze it gray while paused.
- Make the transcribe-and-send wiring test assert the contiguous branch.
- Drop the orphaned chatInput.stopDictation i18n key.

📝 Walkthrough

Walkthrough

Changes

The dictation flow now supports pause/resume, live waveform feedback, audio preview, review actions, transcription retries, timeout errors, and separate insert, send, and queue actions. The composer renders a dedicated recording interface with localized controls. The CSP permits same-origin and blob media. The systemd install test isolates an inherited environment variable.

Dictation capture and transcription

Layer / File(s) Summary
Capture, review, and transcription state
hooks/useDictation.ts, hooks/useDictation.test.mjs, hooks/useDictation.behavior.test.mjs
useDictation tracks pause timing, audio analysis, captured audio, preview playback, review state, transcription errors, timeouts, and retries. Tests cover capture, pause/resume, preview, confirmation, cancellation, cleanup, and transcript routing.

Composer recording interface

Layer / File(s) Summary
Composer recording interface
components/RecordingDeck.tsx, components/ChatInput.tsx, app/globals.css, lib/i18n/locales/*.json, next.config.ts, CHANGELOG.md
The composer renders RecordingDeck during dictation states. The deck supports waveform preview, seeking, playback, discard, and transcribe-and-send actions. Composer actions support insert, send, queue, cancel, retry, and keyboard handling. Locales, media policy, styling, and changelog text describe the updated flow.

Systemd install test

Layer / File(s) Summary
Install environment isolation
bin/omp-web-systemd.test.mjs
The install test deletes OMP_WEB_OMP_BIN from the child environment before execution.

hooks/useDictation.ts:327-328
🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Release the stream if capture is cancelled while permission is pending.

If the hook unmounts while getUserMedia() is pending, cleanup sets cancelledRef.current but does not yet have the returned stream. The continuation then assigns the stream, creates a MediaRecorder, and starts recording after unmount. The maximum-duration timer can keep the microphone active for up to five minutes.

Check cancelledRef.current immediately after the await. Stop the returned tracks before returning.

Proposed fix
 const stream = await navigator.mediaDevices.getUserMedia({ audio: true });
+if (cancelledRef.current) {
+  stream.getTracks().forEach((track) => track.stop());
+  return;
+}
 streamRef.current = stream;

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Send reviewed dictation through confirmTranscribeDictation.

In review mode, MediaRecorder is inactive and the audio is stored in pendingAudioRef. The primary button calls stopAndSendDictation, which delegates to finishCapture; its inactive-recorder guard returns before transcription starts. The button therefore does nothing.

Set the "send" mode before confirming the pending recording. Keep stopAndSendDictation for active or paused capture.

+ const confirmAndSendDictation = useCallback(() => {
+   dictationAfterRef.current = "send";
+   confirmTranscribeDictation();
+ }, [confirmTranscribeDictation]);
+
 ...

+   isReviewing

Use a label that matches the review confirmation behavior.

Normal review entry leaves dictationAfterRef.current as null. confirmTranscribeDictation then transcribes and inserts the result; it does not send it. A primary send action can set the ref to "send" while review mode is active, so the same confirmation button can send instead. The current label does not match the default behavior and is not consistent across paths.

Use a neutral label such as “Transcribe” or “Insert transcription” for chatInput.transcribeDictation. Update the English, Japanese, and Chinese translations. The atActiveIndex state declaration in components/ChatInput.tsx is unrelated and does not need a change.
