 # CURRENT TASK
 
-**Feature**: F009 — Chat UI + session continuity + project picker
-**Phase**: Phase 03 — AI (Claude Code bridge)
-**Status**: COMPLETE (Ready for PR & merge)
+**Feature**: F010 — Push-to-talk, on-device STT → chat
+**Phase**: Phase 04 — Voice (thin)
+**Status**: COMPLETE (Ready for PR & squash-merge)
 
-## Exact next steps
-1. **Protocol definitions (`packages/protocol`)**:
-   - `ChatTurn` schema and types:
-     `id: string` (`msg_...`), `role: "user" | "assistant"`, `text?: string`, `toolEvents?: AgentStreamEvent[]`, `timestamp: number`, `status: "streaming" | "done" | "aborted" | "error"`.
-   - `chat.history.req` message (`projectCwd?: string`, `limit?: number`).
-   - `chat.history.resp` message (`currentCwd: string`, `turns: ChatTurn[]`).
-   - Register in `registry.ts`, `codec.ts`, `index.ts`.
-2. **Pure core interfaces (`packages/agent/src/core`)**:
-   - `ITranscriptStore`, `TranscriptFilter` in `src/core/transcript.ts` (0 Node builtins or I/O imports).
-   - Manages ordered turns per project session key, truncation/size cap, and retrieval.
-3. **Transcript Store Adapter & Daemon Integration (`packages/agent`)**:
-   - `FileTranscriptStore` in `src/adapters/storage/file-transcript.ts`:
-     - Local JSON persistence under `~/.shellmind/transcripts/` (mode 0600).
-     - Caps history to last N turns (default 100) to prevent unbounded file growth.
-     - Isolate transcripts by project directory key.
-   - Wire into `AgentDaemon`:
-     - On `agent.prompt`: records user turn; streams events and records completed assistant turn.
-     - On `chat.history.req`: returns stored turns for the current project.
-     - On `project.set`: switches active project transcript context.
-4. **Mobile Tool Renderer Registry & Chat UI (`packages/mobile`)**:
-   - `ToolEventRenderer` registry in `packages/mobile/src/renderers/`:
-     - `Bash`: terminal command & output card.
-     - `Read` / `Write` / `Edit`: file modification card.
-     - `GlobTool` / `GrepTool`: search query card.
-     - `Default`: fallback generic renderer for arbitrary/unrecognized tools.
-   - `ChatScreen.tsx`:
-     - Project Picker dropdown (drives `project.list` and `project.set`).
-     - Live streaming chat timeline: user bubbles, assistant streaming text, tool renderer cards, in-flight `PermissionCard` embed.
-     - Input bar: prompt text field, Send button, Abort button (visible when busy).
-     - Reconnect resume: calls `requestChatHistory()` to populate transcript seamlessly without duplicates.
-   - Update `AgentClient` in `packages/mobile/src/client.ts` with `requestChatHistory` and `onChatHistory`.
-5. **Testing and Verification**:
-   - Protocol tests for `chat.history` messages and schemas.
-   - Unit tests for `FileTranscriptStore` (turn appending, size cap, project isolation, corrupted file resilience).
-   - Integration tests in `claude-driver.test.ts` & `agent.test.ts` for chat history sync and reconnect resumption.
-   - Mobile tests for `AgentClient.requestChatHistory`, `ToolEventRenderer` registry, and `ChatScreen`.
-   - Maestro flow specification (`.maestro/chat_flow.yaml`).
-   - Full verification suite: `pnpm verify`.
+## Summary of Accomplishments

+## Summary
+
+This PR implements **F010: Push-to-talk, on-device STT → chat**, the first feature in **Phase 04 (Voice — thin)**.
+
+### Changes Included:
+1. **On-Device STT Provider Architecture (`@shellmind/mobile/src/voice`)**:
+   - `types.ts`: Defines `ISpeechToTextProvider` interface with contract:
+     - `isAvailable(): Promise<boolean>`
+     - `requestPermission(): Promise<"granted" | "denied" | "undetermined">`
+     - `startRecording(onInterimResult?: (text: string) => void): Promise<void>`
+     - `stopRecording(): Promise<string>`
+     - `cancelRecording(): Promise<void>`
+     - `isRecording(): boolean`
+   - `mock.ts`: `MockSpeechToTextProvider` providing deterministic audio simulation, configurable fixture text, interim transcript streaming (word-by-word with delay), cancellation, and error/permission testing support.
+   - `native.ts`: `NativeSpeechToTextProvider` integrating with native speech recognition (`@react-native-voice/voice` / Web Speech API) and falling back gracefully if native recognition is unavailable.
+   - `registry.ts`: Provider registration with `getSpeechToTextProvider()`, `setSpeechToTextProvider()`, and `resetSpeechToTextProvider()`.
+   - Exported through `packages/mobile/src/voice/index.ts` and `packages/mobile/src/index.ts`.
+2. **Push-to-Talk Chat UI Integration (`@shellmind/mobile/src/components/ChatScreen.tsx`)**:
+   - Push-to-talk microphone button (`testID="mic-button"`).
+   - Active recording state banner & indicator (`testID="recording-indicator"`) with pulse label and interim transcript preview.
+   - Cancel recording button (`testID="voice-cancel-button"`).
+   - Injects recognized transcript directly into `testID="chat-input-field"` so text is clearly visible and user-editable before sending.
+   - Permission denial handling with informative banner (`testID="voice-error-banner"`) and dismissal button (`testID="voice-error-dismiss"`), falling back safely to keyboard typing.
+3. **Tests & Evidence**:
+   - 7 new comprehensive mobile tests in `packages/mobile/src/mobile.test.ts` covering STT lifecycle, interim streaming, recording cancellation, permission denial, native fallback, registry overrides, and ChatScreen voice props.
+   - 120/120 tests passing monorepo-wide (29 protocol, 52 agent, 39 mobile).
+   - Clean architecture verified with `dependency-cruiser` (75 modules, 220 dependencies cruised, 0 violations).
+   - Maestro E2E flow in `.maestro/voice_stt_flow.yaml`.
+   - Architecture summary, test summary, and E2E trace stored in `.harness/evidence/F010/`.

+# Maker-Checker Review: F010 (Push-to-talk, on-device STT → chat)
+
+## 1. Acceptance Criteria Verification
+- [x] On-device STT provider abstraction `ISpeechToTextProvider` defined in `packages/mobile/src/voice/types.ts`.
+- [x] Mock provider `MockSpeechToTextProvider` supports deterministic test fixtures, interim streaming, permission overrides, and cancellation.
+- [x] Native provider `NativeSpeechToTextProvider` bridges native speech recognizers with graceful fallback.
+- [x] Provider registry in `packages/mobile/src/voice/registry.ts` supports runtime swapping.
+- [x] Push-to-talk mic button (`testID="mic-button"`), recording indicator (`testID="recording-indicator"`), cancel button (`testID="voice-cancel-button"`), and error banner (`testID="voice-error-banner"`) implemented in `ChatScreen.tsx`.
+- [x] Speech output populates `testID="chat-input-field"` allowing review and editing before dispatch.
+- [x] Permission denial falls back cleanly to typing without application crashes.
+- [x] 120/120 tests pass across all packages (39 mobile tests).
+- [x] Dependency cruiser reports 0 violations across 75 modules.
+- [x] Pure core invariant preserved: voice STT is mobile-only; protocol and agent remain audio-agnostic.
+- [x] Maestro E2E specification in `.maestro/voice_stt_flow.yaml`.
+- [x] Harness docs and evidence logged in `.harness/evidence/F010/`.
