## Execution Log

### T1: Add recorder state and browser capture hook

**Status**: Completed
**Files Changed**:
- `web/src/components/MemoEditor/hooks/useVoiceRecorder.ts`
- `web/src/components/MemoEditor/hooks/index.ts`
- `web/src/components/MemoEditor/state/types.ts`
- `web/src/components/MemoEditor/state/actions.ts`
- `web/src/components/MemoEditor/state/reducer.ts`
- `web/src/components/MemoEditor/services/memoService.ts`
**Validation**: `cd web && pnpm lint` — PASS
**Path Corrections**: Added `web/src/components/MemoEditor/services/memoService.ts` after plan update because `memoService.fromMemo()` also constructs `EditorState`.
**Deviations**: None after the approved plan correction.

Implemented a dedicated `voiceRecorder` editor state slice, reducer/actions for recorder lifecycle updates, a browser `MediaRecorder` hook that produces a `LocalFile` preview, and the matching `fromMemo()` defaults needed to keep the editor state shape valid for existing memo edit flows.

### T2: Add composer recorder UI and draft audio handling

**Status**: Completed
**Files Changed**:
- `web/src/components/MemoEditor/components/VoiceRecorderPanel.tsx`
- `web/src/components/MemoEditor/components/EditorToolbar.tsx`
- `web/src/components/MemoEditor/components/index.ts`
- `web/src/components/MemoEditor/index.tsx`
- `web/src/components/MemoEditor/types/components.ts`
- `web/src/components/MemoEditor/types/attachment.ts`
- `web/src/components/MemoMetadata/Attachment/AttachmentListEditor.tsx`
- `web/src/components/MemoEditor/services/validationService.ts`
- `web/src/locales/en.json`
**Validation**: `cd web && pnpm lint` — PASS
**Path Corrections**: None
**Deviations**: None

Added a `Voice note` action to the editor tool dropdown, wired the memo editor to start recording and render an inline recorder/review panel, let users keep a completed clip as a normal draft `LocalFile`, rendered local audio drafts with playable controls in the attachment editor, and blocked save only while permission is pending or recording is live.

## Completion Declaration

**Execution completed successfully** — the frontend memo composer now has a tool-dropdown voice recorder entrypoint that creates draft audio files through the existing attachment flow, with no backend or transcription changes.
