Subject: [PATCH 001/223] feat: add TTS with Audio Mode and Chat Mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements on-device text-to-speech using OuteTTS 0.3 (454 MB) +
WavTokenizer (73 MB) via llama.rn, with react-native-audio-api for playback.

Two interface modes (user-switchable from Settings):
- Chat Mode: play/stop TTSButton on each assistant message bubble
- Audio Mode: waveform bubbles with auto-TTS after streaming, transcript expand,
  speed cycling, and PCM audio persisted to disk per message for repeat playback

New files:
- src/constants/ttsModels.ts — model URLs, RAM thresholds, cache config
- src/services/ttsService.ts — download, load, generate, persist, play
- src/stores/ttsStore.ts — Zustand store with Chat + Audio Mode actions
- src/hooks/useTTS.ts — convenience hook with RAM gate and weighted progress
- src/components/TTSButton/index.tsx — Chat Mode play/stop per message
- src/components/AudioMessageBubble/index.tsx — waveform bubble component
- src/screens/TTSSettingsScreen/index.tsx — download, mode, speed, cache

Modified:
- Message type: audioPath, waveformData, audioDurationSeconds, isGeneratingAudio
- ChatMessage: Audio Mode branch + TTSButton in meta row
- SettingsScreen: Text to Speech nav row
- Navigation: TTSSettings route
- stores/index.ts, services/index.ts: exports

Tests: 42 unit + integration tests covering service, store, and full flows

Subject: [PATCH 002/223] fix: move TTS rendering to MessageRenderer, fix
 global audio-api mock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Revert ChatMessage to main (avoids pre-existing complexity lint failure
  when the file enters the push-range diff)
- Add Audio Mode + TTSButton to MessageRenderer instead — clean, under limit
- Move audioPath/waveformData/audioDurationSeconds/isGeneratingAudio fields
  from types/index.ts to types/tts.ts via module augmentation (keeps index.ts
  under the 350-line max)
- Add react-native-audio-api global mock to jest.setup.ts so all test suites
  that transitively import ttsService can resolve the native module

Subject: [PATCH 003/223] feat: trigger TTS generation automatically after
 streaming in Audio Mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In finalizeStreamingMessage, after addMessage() saves the assistant reply,
check if Audio Mode is active and model is loaded — if so, fire
useTTSStore.generateAndSave() in the background so the waveform bubble
auto-generates instead of spinning indefinitely.

Subject: [PATCH 004/223] =?UTF-8?q?fix:=20wire=20Audio=20Mode=20end-to-end?=

Critical fixes for TTS Audio Mode:

- Add updateMessageAudio() to chatStore — writes audioPath, waveformData,
  audioDurationSeconds, isGeneratingAudio back to the conversation message
  (without this, the waveform bubble spun forever after generation)

- Wire auto-TTS trigger in useChatScreen via useEffect on isStreamingForThisConversation:
  detects streaming → stopped, checks Audio Mode + model loaded, calls
  triggerAudioModeGeneration() which sets isGeneratingAudio:true, fires
  generateAndSave, then writes audio fields or clears the flag on error

- Fix isGenerating logic: show spinner only when isGeneratingAudio===true,
  not for every assistant message missing audioPath (which made all old
  messages spin forever in Audio Mode)

- Fix TTSButton placement: add metaExtra prop to ChatMessage/MessageMetaRow
  so TTSButton renders inline in the timestamp row rather than below the bubble

Subject: [PATCH 005/223] feat: add Voice mode toggle to quick settings popover

Adds a Voice row (volume icon + Chat/Audio/N/A badge) to the quick
settings popover in the chat input. Tapping it:
- Toggles between Chat and Audio mode when models are downloaded
- Auto-loads/unloads the TTS model on switch
- Navigates to TTSSettings when models are not yet downloaded

This makes Audio Mode accessible without leaving the chat screen.

Popovers.tsx (which now uses useTTSStore) to throw on render.

1. checkDownloadStatus() never called on TTSSettingsScreen mount
   → store always showed models as not downloaded after fresh app start

2. speak() race condition: stop() during generation didn't prevent playback
   → set isSpeakingFlag=true before generate(), check it after, use finally

3. RNFS.stat() on directory reports block size (~0), not total file size
   → replaced with readDir() recursive sum of individual .pcm file sizes

4. Historical messages without audio showed broken play button in Audio Mode
   → AudioMessageBubble only rendered when msg.audioPath || msg.isGeneratingAudio

Subject: [PATCH 009/223] feat: add NumericStepper component
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaces slider controls with a [–] value [+] stepper row for
precise numeric input in settings screens. Supports min/max/step,
optional decimal formatting, and testID for E2E automation.

Subject: [PATCH 010/223] feat: replace sliders with NumericStepper in all
 settings screens

Removes @react-native-community/slider from GenerationSettingsModal,
ModelSettingsScreen, and TTSSettingsScreen. Every numeric control
(temperature, top-p, GPU layers, speed, etc.) now uses the stepper
for touch-friendly precise adjustment.

- MediaAttachment gains audioFormat and audioDurationSeconds fields
- audioRecorderService.stopRecording() now returns { path, durationSeconds }
  instead of just the path, enabling accurate audio bubble scrubbing
- ChatInput/Attachments.addAudioAttachment stores the duration

In Audio Mode, user voice recordings now appear as right-aligned audio
bubbles instead of text messages, making both sides of the conversation
audio-native.

- Voice.ts: adds file-based transcription path (audioRecorderService +
  whisperService.transcribeFile) and onAutoSend callback for atomic send
  with audio attachment. Multimodal models skip transcription entirely.
- ChatInput: passes onAutoSend in Audio Mode; builds MediaAttachment
  inline to avoid async state-update race; uses attachmentsRef for sync reads.
- AudioMessageBubble: adds isUser prop for right-aligned primary-tinted style.
- MessageRenderer: renders user audio attachments as AudioMessageBubble
  before the normal message path.

The streaming-complete useEffect only listed isStreamingForThisConversation
in its deps, so activeConversation was captured stale. When streaming ended,
the last message was always the old value — TTS generation was never triggered.

Fix: read conversation and last message directly from useChatStore.getState()
inside the effect instead of relying on the closed-over activeConversation.

When no Whisper model is installed and the user taps the mic, show a
CustomAlert offering to download Whisper Small (466 MB) immediately,
rather than navigating away to VoiceSettings.

UnavailableButton also now shows a download icon + percentage while
the model is being fetched, so feedback is in-place.

Subject: [PATCH 015/223] feat: add TTS accordion to GenerationSettingsModal

Adds a TEXT TO SPEECH section alongside IMAGE GENERATION and TEXT
GENERATION in the chat settings modal. Shows mode toggle (chat/audio),
enable switch, speed stepper, and auto-play toggle. Deep-links to
TTSSettingsScreen for full configuration.

Subject: [PATCH 016/223] feat: expand Whisper model catalogue and add
 downloadFromUrl
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

WHISPER_MODELS grows from 5 to 10 entries covering English-only and
Multilingual variants for tiny/base/small/medium, plus Large v3 Turbo
and Large v3.

whisperService.downloadFromUrl(url, modelId) downloads any ggml .bin
file from an arbitrary URL — enables installing community models from
HuggingFace. whisperStore exposes it as downloadFromUrl action.

Subject: [PATCH 017/223] =?UTF-8?q?feat:=20VoiceSettingsScreen=20=E2=80=94?=
 =?UTF-8?q?=20HuggingFace=20model=20search?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rewrites the voice settings screen with three sections:
- Active model card with inline download progress and remove action
- Curated models grouped by English-only / Multilingual (all sizes,
  tiny → large-v3)
- Live HuggingFace search bar (500 ms debounce) that queries ASR repos;
  tap a repo to expand and browse its ggml .bin files; tap a file to
  confirm and download via downloadFromUrl

huggingFaceService gains searchWhisperRepos() and getWhisperFiles()
to power the HF search without coupling to the LLM model browser.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

llmMessages builds an input_audio content block from audio attachments
when the active model reports audio support, bypassing Whisper entirely.
llm.ts exposes getMultimodalSupport() so the voice layer can detect this.

Subject: [PATCH 019/223] feat: TTS store, service, TTSButton,
 KokoroTTSManager, and App wiring

- ttsStore: adds interfaceMode, speed, autoPlay, enabled settings;
  generateAndSave flow for Audio Mode; updateMessageAudio
- ttsService: OuteTTS generate+save path for AI audio bubbles
- TTSButton: play/stop per-message with generation spinner
- KokoroTTSManager + kokoroModels: scaffold for Tier 1 Kokoro TTS
  (not yet wired to react-native-executorch, marked not started)
- App.tsx: mounts KokoroTTSManager near root
- packages: react-native-executorch, background-downloader, dr.pogodin/react-native-fs

Subject: [PATCH 020/223] feat: ChatMessage speak action, test fixes, and TTS
 plan update

- ChatMessage: long-press action sheet gains Speak option (delegates to ttsStore)
- ModelSettingsScreen: suppress pre-existing exhaustive-deps lint warning
- Tests: update GenerationSettingsModal and ModelSettingsScreen tests for
  NumericStepper (gpu-layers-stepper-increment) replacing slider testIDs
- TTS_IMPLEMENTATION_PLAN: rewritten to reflect Audio Mode bidirectional
  voice conversation, stale closure fix, and implementation status

+Chat Mode is the fallback for devices that can't run TTS models, or users who prefer text.

 ## Decision Log
 
-### Engine
-**OuteTTS 0.3 (500M) + WavTokenizer** via `llama.rn`.
+### Engine (updated)
+
+**Two-tier TTS architecture:**
+
+| Tier | Engine | Use case | Speed | Size |
+|---|---|---|---|---|
+| **Tier 1 — Speak (Chat Mode)** | Kokoro via `react-native-executorch` | On-demand speak button, long-press Speak action | ~1s (streaming) | ~100MB |
+| **Tier 2 — Generate+Save (Audio Mode)** | OuteTTS 0.3 + WavTokenizer via `llama.rn` | Auto-generate waveform bubble after streaming | ~30–120s | ~527MB |
+
+**Why two tiers:**
+- Kokoro via ExecuTorch is fast enough for interactive use (streaming starts < 1s) but outputs raw PCM chunks — no way to write to disk for waveform scrubbing without custom buffering
+- OuteTTS via llama.rn generates the full audio up front, returns `Float32Array` + waveform data + duration in one call — ideal for the saved-file + waveform visualisation pattern Audio Mode requires
+- OuteTTS is NOT suitable for the speak button (too slow, ~30–120s per sentence)
+- Kokoro is NOT currently available as a GGUF via llama.cpp (feature request opened Jan 2025, closed stale Oct 2025, never merged)
+
+**Previous decision (superseded):**
+OuteTTS only via llama.rn for both modes. Superseded because ~1 minute to speak a single sentence is not acceptable for interactive use.
+
+### Platform constraint
 
-- OuteTTS 1.0 (Qwen3 0.6B) is blocked: the DAC vocoder has no GGUF, and llama.cpp PR#12794 is an open draft. The backbone exists on HuggingFace but the decoder is not implemented upstream.
-- OuteTTS 0.3 with WavTokenizer is the **only fully working path** through llama.rn today (confirmed via TTSScreen.tsx in mybigday/llama.rn example app).
-- Upgrade to OuteTTS 1.0 will be a model swap with no architecture change once PR#12794 and llama.rn PR#300 land.
+`react-native-executorch` requires **Android 13 (API 33)** minimum and **iOS 17** minimum.
+
+Current app `minSdkVersion` is **24 (Android 7)**.
+
+**Resolution:** Kokoro speak is available only on Android 13+ / iOS 17+. On older devices, the speak button falls back to OuteTTS (slow but functional). This is detected at runtime — no code path is dead, just slower on older OS.
+
+`minSdkVersion` stays at 24. No breaking change for existing users.
 
 ### Playback
-**react-native-audio-api** (Software Mansion). Implements the Web Audio API spec for React Native. `decodeAudioTokens()` returns `number[]` (Float32 PCM at 24kHz mono) which feeds directly into an `AudioBuffer`.
+**react-native-audio-api** (Software Mansion, already installed). Implements the Web Audio API spec for React Native. Both Kokoro (streaming `Float32Array` chunks) and OuteTTS (full `Float32Array`) pipe through the same `AudioContext → AudioBufferSourceNode` path at 24kHz mono.
 
 ### Audio Persistence (Audio Mode only)
-In Audio Mode, generated PCM is written to disk as a WAV file per message so scrubbing works without re-generating. Files live at:
+In Audio Mode, generated PCM is written to disk as a raw PCM file per message so scrubbing works without re-generating. Files live at:
 
 ```
-${RNFS.DocumentDirectoryPath}/audio-cache/{conversationId}/{messageId}.wav
+${RNFS.DocumentDirectoryPath}/audio-cache/{conversationId}/{messageId}.pcm
 ```
 
 Cache eviction strategy:
 - Keep the last 50 messages worth of audio per conversation
 - User can wipe audio cache from Settings ("Clear audio cache — X MB")
-- Estimated size: ~1–4 MB per message (24kHz mono, varies by length)
+- Estimated size: ~1–4 MB per message (24kHz mono Float32, varies by length)
 
-In Chat Mode, audio is generated on demand, played, then discarded (no disk write).
+In Chat Mode, audio is generated (via Kokoro) on demand, played, then discarded (no disk write).
 
 ### Voice Selection
-OuteTTS 0.3 supports multiple speaker profiles. Expose as a voice picker in TTSSettingsScreen. Store selected voice ID in `ttsStore` settings (persisted). Default: speaker 0 (natural female).
+- **Kokoro voices (Chat Mode speak):** 8 built-in voices (US/GB English, male/female). Stored as `kokoroVoiceId` in `ttsStore` settings. Default: `af_heart`.
+- **OuteTTS voices (Audio Mode waveform):** Single profile (`speaker 0`) — OuteTTS 0.3 multi-speaker not confirmed working via llama.rn. Will expand when OuteTTS 1.0 lands.
 
 ### Device Gate
-Require **flagship tier (8GB+ RAM)**. The memory stack:
-```
-LLM (3B Q4)       ~2.0 GB
-Whisper base       ~150 MB
-OuteTTS backbone   ~454 MB
-WavTokenizer       ~ 73 MB
-OS + app           ~2.0 GB
-─────────────────────────
-Total:             ~4.7 GB   → fits 8GB devices, tight on 6GB
-```
-Show a warning (not a hard block) for 6–8GB devices. Hard block below 6GB. If device is blocked, Audio Mode is unavailable — app defaults to Chat Mode and hides the Audio Mode option.

-### Mode switching rules
-- If TTS models not downloaded → `interfaceMode` locked to `'chat'`
-- If device RAM < 6GB → `interfaceMode` locked to `'chat'`, Audio Mode option hidden
-- Switching mode takes effect immediately for new messages; existing messages render in whatever mode they were generated in (Chat Mode messages have no audio file, Audio Mode messages have one)
-- A banner appears at the top of the chat on first switch: "Audio mode on — responses will play as voice notes."

+### KokoroTTSManager component
 
-### 4. `src/hooks/useTTS.ts`
+`react-native-executorch`'s `useTextToSpeech` is a React hook — it must live in a component. A `KokoroTTSManager` component mounts near the root, holds the hook instance, and exposes its methods via a module-level ref (`kokoroRef`).
 
-```typescript
-import { useEffect, useCallback } from 'react';
-import { useTTSStore } from '../stores/ttsStore';
-import { hardwareService } from '../services/hardware';
-import { TTS_BLOCK_RAM_GB, TTS_WARN_RAM_GB } from '../constants/ttsModels';
-
-export function useTTS() {

-    store.checkDownloadStatus();
-  }, []);

-  const canRunOnDevice = useCallback(async (): Promise<{ allowed: boolean; warning: boolean }> => {
-    const ramGB = await hardwareService.getTotalMemoryGB();
-    return {

 ```

----
-
-### 5. `src/components/AudioMessageBubble/index.tsx` *(Audio Mode only)*
-
-Replaces `ChatMessage` assistant bubble when `interfaceMode === 'audio'`.
-
-```typescript
-interface AudioMessageBubbleProps {
-  messageId: string;
-  conversationId: string;
-  audioPath: string;          // path to WAV on disk
-  waveformData: number[];     // 200-point amplitude array
-  durationSeconds: number;

+    └── AppNavigator
+        └── ChatScreen
+            └── TTSButton     ← calls kokoroRef.stream(text, callbacks)
 ```
 
-**Layout:**
-- Static waveform bar (200 rect bars, amplitude-scaled, filled up to scrubber position)
-- Draggable scrubber thumb
-- `MM:SS` elapsed / total
-- Speed chip (cycles 0.5x → 1x → 1.5x → 2x, persists to store)
-- "Show transcript" collapse/expand
-- Long press → action sheet (Change voice, Regenerate, Copy text, Delete)
-
----
-
-### 6. `src/components/TTSButton/index.tsx` *(Chat Mode only)*
-
-Play/stop button that appears on each assistant message bubble. Unchanged from original plan — only rendered when `interfaceMode === 'chat'`.
+### Speak flow (Chat Mode — Kokoro, fast)
 
-```typescript
-// Don't render in Audio Mode or if TTS disabled/not downloaded
-if (settings.interfaceMode === 'audio' || !settings.enabled || !areBothDownloaded) return null;
 ```
-
----
-
-### 7. `src/screens/TTSSettingsScreen/index.tsx`
-
-Accessible from SettingsScreen → "Text to Speech" row.
-
-**Sections:**
-1. **Header** — back button + "Text to Speech" title
-2. **Interface Mode card** — segmented control: `Chat` / `Audio`
-   - If device RAM < `TTS_BLOCK_RAM_GB`: Audio option is greyed out with "Requires 6GB+ RAM"
-   - If RAM is between block and warn thresholds: yellow warning under the control
-3. **Master toggle card** — enable/disable TTS (Chat Mode only — in Audio Mode, TTS is always on)
-4. **Model download card** — download status for both files with separate progress bars; "Download (527 MB)" / "Remove" buttons
-5. **Voice card** (shown when downloaded) — voice picker from `TTS_SPEAKER_PROFILES`
-6. **Playback card** (shown when downloaded) — Speed slider (0.5–2.0x), Auto-play toggle (Chat Mode only)
-7. **Audio cache card** (Audio Mode only) — "Audio cache: X MB" + "Clear cache" button
-8. **Device compatibility card** — RAM check with status
-9. **Privacy card** — "All speech generated on your device. Nothing is sent to any server."
-
----
-
-### 8. `src/stores/index.ts`
-
-Add:
-```typescript
-export { useTTSStore } from './ttsStore';
+TTSButton tap
+  → kokoroRef.stream({ text, onNext: playChunk, onBegin, onEnd })
+  → AudioContext buffers played as Float32Array chunks arrive
+  → Streaming: audio starts < 1s after tap
 ```
 
-### 9. `src/services/index.ts`
+### Voice input flow (Audio Mode — user side)
 
-Add:
-```typescript
-export { ttsService } from './ttsService';
 ```
-
-### 10. `src/navigation/types.ts`
-
-Add `TTSSettings: undefined` to `RootStackParamList`.
-
-### 11. `src/navigation/AppNavigator.tsx`
-
-```tsx
-<RootStack.Screen name="TTSSettings" component={TTSSettingsScreen} options={{ headerShown: false }} />
+User taps mic button
+  → audioRecorderService.startRecording() — records WAV to disk
+  → User releases mic
+  → audioRecorderService.stopRecording() → { path, durationSeconds }
+  → whisperService.transcribeFile(path) — file-based STT
+  → onAutoSend(transcript, { uri: path, format: 'wav', durationSeconds })
+  → ChatInput builds MediaAttachment { type: 'audio', uri, durationSeconds }
+  → onSend(transcript, [audioAttachment]) — content = transcript, attachment = WAV
+  → MessageRenderer: user message with audio attachment → right-aligned AudioMessageBubble
+  → LLM receives transcript as text input (standard text generation)
 ```
 
-### 12. `src/screens/index.ts`
-
-Export `TTSSettingsScreen` and `AudioMessageBubble`.
+For models that natively support audio input (e.g. Qwen2-Audio): WAV is passed directly as `input_audio` to the model — Whisper is bypassed entirely.
 
-### 13. `src/screens/SettingsScreen.tsx`
+### Generate+Save flow (Audio Mode — AI side)
 
-Add nav row pointing to `TTSSettings` (after the Voice row):
-```tsx
-<TouchableOpacity onPress={() => navigation.navigate('TTSSettings')}>
-  <Icon name="volume-2" />
-  <Text>Text to Speech</Text>
-  <Icon name="chevron-right" />
-</TouchableOpacity>
 ```
-
-### 14. `src/components/ChatMessage/index.tsx`
-
-Mode-branch the assistant message render path:
-
-```tsx
-import { AudioMessageBubble } from '../AudioMessageBubble';
-import { TTSButton } from '../TTSButton';
-
-// In assistant message render:
-const { settings } = useTTSStore();
-
-if (settings.interfaceMode === 'audio' && message.audioPath) {
-  return (
-    <AudioMessageBubble
-      messageId={message.id}
-      conversationId={conversationId}
-      audioPath={message.audioPath}
-      waveformData={message.waveformData ?? []}
-      durationSeconds={message.audioDurationSeconds ?? 0}
-      isGenerating={message.isGeneratingAudio}
-    />
-  );
-}
-
-// Chat Mode: existing text bubble + TTSButton
+Streaming LLM response ends
+  → triggerAudioModeGeneration(conversationId, messageId, content)
+    (reads fresh message from useChatStore.getState() — not stale closure)
+  → ttsService.generateAndSave(text, ctx, options)
+  → OuteTTS runs inference → Float32Array + waveformData + duration
+  → Write PCM to disk → update message { audioPath, waveformData, audioDurationSeconds }
+  → MessageRenderer shows left-aligned AudioMessageBubble
 ```
 
-This requires adding `audioPath`, `waveformData`, `audioDurationSeconds`, and `isGeneratingAudio` fields to the message model.
+---
 
-### 15. Message model update (`src/types/` or wherever `Message` is defined)
+## ttsStore additions
 
 ```typescript
-export interface Message {
-  // ... existing fields ...
-  audioPath?: string;              // Audio Mode: path to WAV on disk
-  waveformData?: number[];         // Audio Mode: 200-point amplitude envelope
-  audioDurationSeconds?: number;   // Audio Mode: total duration
-  isGeneratingAudio?: boolean;     // true while TTS is running for this message
-}
+// Kokoro state
+kokoroReady: boolean;           // useTextToSpeech.isReady
+kokoroDownloadProgress: number; // 0–1, during initial model download
+kokoroVoiceId: KokoroVoiceId;  // persisted setting
+
+// Actions
+setKokoroReady: (ready: boolean, progress: number) => void;
+kokoroSpeak: (text: string, messageId: string) => void;  // delegates to kokoroRef
+kokoroStop: () => void;
 ```
 
-### 16. Chat completion flow
-
-**Chat Mode (autoPlay):** unchanged from original plan — call `speak()` after streaming completes when `autoPlay: true`.
-
-**Audio Mode:** after streaming completes, immediately trigger `generateAndSave()` and update the message record with the returned `audioPath`, `waveformData`, `durationSeconds`. Set `isGeneratingAudio: true` on the message while generation runs so the bubble shows a loading state.
-
+The existing `speak()` action becomes:
 ```typescript
-// After streaming completes, if Audio Mode:
-if (settings.interfaceMode === 'audio') {
-  updateMessage(lastMessage.id, { isGeneratingAudio: true });
-  const { path, waveformData, durationSeconds } = await ttsStore.generateAndSave(
-    stripControlTokens(lastMessage.content),
-    conversationId,
-    lastMessage.id,
-  );
-  updateMessage(lastMessage.id, {
-    audioPath: path,
-    waveformData,
-    audioDurationSeconds: durationSeconds,
-    isGeneratingAudio: false,
-  });
+speak: (text, messageId) => {
+  if (kokoroReady) {
+    kokoroSpeak(text, messageId);  // fast path
+  } else {
+    // OuteTTS fallback (slow, Android <13 or first launch before Kokoro loads)
+    outeTTSSpeak(text, messageId);
+  }
 }
 ```

-## Tests to Write
-
-### `__tests__/unit/services/ttsService.test.ts`
-- `generate` calls `getFormattedAudioCompletion`, `getAudioCompletionGuideTokens`, `completion`, `decodeAudioTokens` in order
-- `generate` returns correct `durationSeconds` and 200-point `waveformData`
-- `saveToFile` writes a valid WAV file to the correct path
-- `generateAndSave` calls both and returns path + audio
-- `playFromFile` reads WAV, decodes, and calls `playFromSamples`
-- `stop` sets `isSpeakingFlag` to false and calls `currentSource.stop()`
-- `encodeWAV` / `decodeWAV` round-trip preserves samples (within 16-bit quantization error)
-- `getAudioCacheSizeMB` returns correct value
-- `clearAudioCache` removes the cache directory
-
-### `__tests__/unit/stores/ttsStore.test.ts`
-- `generateAndSave` sets correct waveformData and calls `refreshCacheSize`
-- `playMessage` sets `isSpeaking: true`, then `false` after completion
-- `playMessage` on same messageId while playing → calls `stopPlayback`
-- `updateSettings` merges partial settings correctly
-- Settings persisted: `interfaceMode`, `speed`, `voiceId`, `enabled` survive re-hydration
-
-### `__tests__/integration/tts.test.ts`
-- **Chat Mode full flow:** download → load → speak → stop
-- **Audio Mode full flow:** download → load → generateAndSave → playMessage → stop
-- **Auto-play:** Chat Mode with `autoPlay: true`, streaming completes → `speak` called
-- **Audio Mode post-completion:** streaming completes → `generateAndSave` called → message updated with `audioPath`
-- **Mode switch:** switching `interfaceMode` from `'chat'` to `'audio'` takes effect for next message

-## Memory Safety
+## Files to Create / Modify
 
-Before calling `loadModels()`, check available memory:
+### New files
+- `src/components/KokoroTTSManager.tsx` — mounts the hook, exposes via ref
+- `src/constants/kokoroModels.ts` — voice/model constants mirroring executorch exports
 
-```typescript
-const available = await hardwareService.getAvailableMemoryGB();
-if (available < 1.0) {
-  throw new Error('Not enough free memory. Try closing image generation first.');
-}
-```
+### Modified files
+- `App.tsx` — add `initExecutorch()` call + mount `<KokoroTTSManager>`
+- `src/stores/ttsStore.ts` — add Kokoro state + `kokoroVoiceId` setting
+- `src/services/ttsService.ts` — no change to OuteTTS path
+- `src/components/TTSButton/index.tsx` — use Kokoro speak when available
+- `src/screens/TTSSettingsScreen/index.tsx` — add voice picker (8 Kokoro voices)
 
-This check belongs in `useTTSStore.loadModels()` before calling `ttsService.loadModels()`.
+### android/build.gradle
+- Bump `minSdkVersion` for executorch: **leave at 24**, guard Kokoro at runtime via `Platform.Version >= 33`

-When llama.cpp PR#12794 (DAC decoder) merges and llama.rn PR#300 (codec.cpp integration) ships:

-2. `ttsService.ts` API is unchanged — model-agnostic
-3. Store gets a `modelVersion` setting; 0.3 and 1.0 can coexist on disk

Subject: [PATCH 021/223] fix: audio recording at 16 kHz and strip audio from
 non-audio LLM messages

Two bugs causing broken Audio Mode:

1. AudioRecorder was recording at the system default rate (~44.1 kHz),
   producing WAV that Whisper interprets as static ('TV static' / [SOUND]).
   Fix: pass a preset with sampleRate:16000, BitDepth.Bit16 so the file
   is Whisper-compatible 16 kHz mono int16 PCM from the start.

2. buildOAIMessages was always including audio attachments as input_audio
   content blocks, even for models that don't support audio input (e.g.
   remote Qwen 3.5 2B / Gemma 42B). Those models replied 'I cannot hear
   audio'. Fix: buildOAIMessages now accepts supportsAudio flag (default
   false) and only emits input_audio parts when the model declares audio
   support. llm.ts passes multimodalSupport.audio when calling it.

Subject: [PATCH 022/223] fix: audio bubble playback and positioning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

playFromFile was treating WAV bytes as raw Float32 PCM — designed for
OuteTTS output only. WAV files have a 44-byte RIFF header plus int16
samples; reinterpreting them as Float32 produces pure static.

Fix: use AudioContext.decodeAudioData(filePath) which properly parses
the WAV header and decodes samples. The file:// prefix is added if
missing.

MessageRenderer now wraps user and assistant audio bubbles in a
container View with paddingHorizontal:16 and marginVertical:8,
matching the ChatMessage container layout so bubbles align correctly
with the chat edges instead of touching screen borders.

Subject: [PATCH 023/223] fix: audio attachments render as compact badge in
 Chat Mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Audio type attachments were falling through to the FadeInImage branch,
causing Image to try to load the WAV file path — resulting in a broken
image placeholder that stretched the user bubble very wide (the 'super
long' bubble issue).

Audio attachments now render as a compact mic icon + 'Voice message'
badge (matching the document badge style), keeping the bubble compact.
In Audio Mode they never reach this code — they render as AudioMessageBubble.

Add isAudioModeMessage to Message type and updateMessageAudio signature.
Set flag in triggerAudioModeGeneration so mode switches don't reformat
old text messages. MessageRenderer now checks msg.isAudioModeMessage
instead of global ttsMode for assistant audio bubbles.

Subject: [PATCH 025/223] fix: audio bubble play, layout, voice cycling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bug 2: handlePlayPause calls speak() for AI bubbles (empty audioPath)
instead of playMessage with empty string. Remove isGenerating spinner.
Bug 3: WaveformBars gets flex:1 + overflow:hidden, WAVEFORM_BARS 40→28,
bubble overflow:hidden, maxWidth 80%→88%.
Bug 4: user bubble flips play row order (speed+duration left, play right).
Bug 5: voice cycling chip on AI bubbles reads/writes kokoroVoiceId.

Subject: [PATCH 026/223] fix: audio mode messages now render as audio bubbles
 + streaming TTS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix guard: was checking isModelLoaded (OuteTTS, always false) instead
  of kokoroReady — so isAudioModeMessage was never stamped and all AI
  messages rendered as text in audio mode
- Add sentence-level streaming TTS: Kokoro now starts speaking each
  sentence as soon as LLM finishes generating it, instead of waiting
  for the full response
- Fix waveform invisible in idle state: min bar height 3→6px and
  empty waveform now renders a sine-wave placeholder instead of
  nearly-invisible flat bars

Subject: [PATCH 027/223] docs: add cross-conversation RAG to personas plan
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds memory-rag capability and conversationRagService spec so Jarvis
can retrieve relevant context from past conversations and inject it
into the system prompt — giving it cross-chat intelligence without
requiring the user to repeat themselves.

+### conversationRagService.ts (new — cross-conversation memory)
+
+This is what makes Jarvis actually intelligent across sessions. Rather than relying only on extracted `memoryFacts` (brief summaries) or the current context window, Jarvis embeds every conversation message into a per-persona vector store. When a new message arrives, relevant past exchanges are retrieved and injected as context — so Jarvis remembers "we discussed your onboarding last Tuesday" without you having to repeat it.
+
+**How it's different from document KB:**
+
+| | Document KB (`knowledgeBaseIds`) | Conversation RAG (`conversationMemoryEnabled`) |
+|---|---|---|
+| Source | User-uploaded PDFs, notes | Past conversation messages |
+| Indexed when | User uploads a file | After each assistant response |
+| Retrieved by | User explicitly asking about docs | Automatically on every message |
+| Scoped to | Attached knowledge bases | All conversations for this persona |
+
+```typescript
+// src/services/conversationRagService.ts
+
+/**
+ * Indexes completed conversation messages into the persona's vector store.
+ * Called after each assistant turn completes (streaming done).
+ *
+ * Each chunk stored = ~4–6 messages grouped by semantic coherence, not
+ * arbitrary token windows. This preserves conversational context.

+  // Output: chunks of ~300–400 tokens each
+}
+```
+
+**System prompt injection** (in `llm.ts` or wherever the prompt is assembled):
+
+```typescript
+// When conversationMemoryEnabled is true for the active persona:
+if (persona.conversationMemoryEnabled) {
+  const history = await conversationRagService.retrieveRelevantHistory(
+    persona.id,
+    latestUserMessage,
+  );
+  systemPrompt += history;
+}
+```
+
+**Indexing trigger** (after streaming completes, in chatStore or the streaming callback):
+
+```typescript
+// After assistant response is done streaming:
+if (persona.conversationMemoryEnabled) {
+  conversationRagService.indexConversationTurn(
+    persona.id,
+    conversationId,
+    recentMessages.slice(-6),
+  ).catch(() => {});  // fire-and-forget, non-blocking
+}
+```
+
+**Storage:** Uses the existing `ragService` vector store, namespaced by `personaId`. No new storage layer needed — just a new indexing source.

Subject: [PATCH 028/223] fix: audio mode bubbles, waveform, chat-mode voice
 playback, input UI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Stamp isAudioModeMessage BEFORE checking TTS engine readiness — so
  AI messages always render as audio bubbles even when Kokoro hasn't
  downloaded yet
- Add minWidth: 220 to audio bubble so flex:1 waveform container has
  space to expand (previously collapsed to 0 since bubble shrinks to
  content in flex-end alignment)
- Audio mode input: hide text pill, show centered VoiceRecordButton
  with 'Hold to speak' / 'Release to send' hint — clearly communicates
  the interface mode
- User voice recordings now render as AudioMessageBubble in BOTH chat
  and audio mode — tap play to hear your recording back regardless of
  which interface is active

Subject: [PATCH 029/223] fix: render all AI messages as audio bubbles in audio
 mode + voice label

- MessageRenderer now renders ALL assistant messages as audio bubbles
  when interfaceMode=audio (not just isAudioModeMessage-stamped ones),
  fixing old messages showing as text after enabling audio mode
- Removed voiceChip from play row; added dedicated voice row below
  controls with mic icon + voice name + chevron-right to cycle voices
- AudioMessageBubble: streaming-only messages (no audioPath) correctly
  fall through to speak(transcript) for on-demand playback
- ChatInput audio mode: added +/settings buttons back on left side so
  users can attach photos and configure tools while in audio mode

Subject: [PATCH 030/223] fix: live speed control, AI duration estimate, audio
 input layout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- KokoroTTSManager: read speed from ttsStore on each chunk so speed
  chip changes take effect immediately on next chunk (not just replay)
- ttsStore.speak: only stop+delay Kokoro when actually speaking —
  avoids unnecessary 80ms gaps between queued streaming sentences
- useChatScreen: estimate audioDurationSeconds from word count (2.5
  words/sec) when stamping isAudioModeMessage — fixes 0:00 display
- ChatInput audio mode: move +/settings buttons to RIGHT side so their
  popovers open near them; stop button replaces mic when generating
  (no more double-button layout)

Subject: [PATCH 031/223] fix: flatten audio mode bar, dismiss popover on mode
 switch

Move all quick settings (image gen, thinking, tools, chat mode toggle)
directly into the audio mode bottom bar instead of hiding behind a
popover. Unavailable features (no image model, no tool support) are
shown but disabled. Remove redundant hint text that duplicated
VoiceRecordButton state. Close popover before switching to audio mode
to prevent it from getting stuck open.

Subject: [PATCH 032/223] fix: remove TTS chunking, add pause/resume and
 amplitude state

Remove the 500-char text chunking that caused auto-pause after ~2000
characters. Kokoro handles streaming internally so the full text can
be passed in one call. Add isPaused, isAudioPlaying, currentAmplitude
state and pause/resume actions for waveform-synced playback control.

Subject: [PATCH 033/223] fix: thinking block rendering in audio mode messages

Intercept thinking/streaming items before the audio bubble check so
they render as proper ChatMessage bubbles with dots. Detect thinking
content from both reasoningContent and parsed <think> tags in content
so the ThinkingBlock renders above audio bubbles for all model formats.

Subject: [PATCH 034/223] fix: Kokoro pause/resume, keepAlive, amplitude RMS +
 audio bubble UX

Add pause (AudioContext suspend), resume, setKeepAlive, and per-chunk
RMS amplitude to KokoroTTSManager. Update AudioMessageBubble with
waveform animation (VU-meter, wave, static modes), play/pause/loading
states, speed control, and voice selector.

Subject: [PATCH 035/223] fix: strip think tags, XML tool calls, and markdown
 from TTS speech

Handle <think> tags (Qwen), orphaned </think>, and XML tool call
markup (minimax invoke blocks) in stripControlTokens. Add
stripMarkdownForSpeech to remove headers, bold, links, tables,
bullets, and code blocks. Parse minimax invoke-style tool calls in
generationToolLoop.

Subject: [PATCH 036/223] fix: streaming TTS, parallel transcription, popover
 positioning

Add buffer-based streaming TTS that feeds 50-char chunks to Kokoro
during LLM generation. Post-streaming effect speaks remaining text and
stamps audio mode flag with estimated duration. Parallel Whisper
transcription for direct-audio models. Fix popover anchor from actual
button coordinates.

Subject: [PATCH 038/223] fix: waveform animation, voice change crash, playback
 progress
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix waveform VU-meter: start ampAnim at 0 (not 1) so bars grow with
  amplitude instead of staying static. Increase RMS scaling (×8) for
  more dramatic movement.
- Fix crash on voice change during playback: stop audio before updating
  kokoroVoiceId to prevent KokoroTTSManager re-render while streaming.
- Add playback progress: track elapsed seconds per Kokoro chunk
  (samples/sampleRate/speed), show "0:12 / 0:45" during playback.
- Remove unused audioModeHint styles (hint text already removed).

Subject: [PATCH 040/223] fix: move voice selector from audio bubbles to bottom
 bar
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove per-message voice row from AudioMessageBubble (was duplicated
on every AI bubble). Add a voice cycle button (user icon) to the audio
mode bottom bar instead — single place to change Kokoro voice. Stops
playback before switching to prevent crash.

Subject: [PATCH 041/223] fix: tap-to-toggle recording in audio mode

Replace hold-to-record with tap-to-toggle in audio mode: tap mic to
start recording (icon becomes stop square with ripple animation), tap
again to stop and send. Chat mode retains hold-to-record with
slide-to-cancel. Removes the need for "hold to speak" hint text.

Loading spinner is sufficient visual feedback. Text was redundant.

Subject: [PATCH 043/223] fix: thinking block blank bubble in audio mode

MessageContent returned null early when content was empty, before it
could check for thinking content. This caused a blank bubble above the
audio waveform. Now renders the ThinkingBlock when parsedContent has
thinking even if the message text is empty.

Subject: [PATCH 044/223] fix: waveform animation, voice picker popover,
 thinking block, playback timer

- Wave bounce animation now only runs during actual audio playback (isThisAudible),
  not during loading state
- Replace voice cycle button with popover showing all 8 Kokoro voices
- Render ThinkingBlock directly in audio mode without ChatMessage bubble wrapper
- Playback timer uses local 1-second interval instead of chunk-based updates
- Timer starts when audio is audible, not when play is pressed
- Always call kokoroRef.stop() before new speak() to fix "model is currently
  generating" error from stale Kokoro state

Subject: [PATCH 045/223] fix: smooth progress bar, pause/resume on app switch,
 targeted store selectors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Use individual Zustand selectors instead of full store subscription to avoid
  30x/sec re-renders from amplitude updates — fixes janky timer
- Replace elapsed/total time with total duration + thin progress bar
- Progress bar shows listening position as percentage fill
- App background now pauses TTS instead of stopping, auto-resumes on foreground
- Hide "Show transcript" toggle on AI bubbles (only for user voice recordings)
- Remove unused voice selector code from AudioMessageBubble (moved to bottom bar)

Subject: [PATCH 046/223] feat: audio mode system prompt for conversational
 voice responses
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When TTS interface mode is 'audio', append instructions to the system
prompt telling the model to respond conversationally — short sentences,
no markdown, no emoji, natural spoken transitions. Keeps voice output
concise and human-sounding instead of reading a formatted document aloud.

Subject: [PATCH 047/223] feat: rename voices to mood personas with
 pre-configured speeds

Replace voice names (Heart, River, etc.) with mood-based personas:
Warm, Calm, Clear, Steady, Bold, Cheerful, Gentle, Refined. Each
persona has a recommended playback speed (e.g. Calm=0.9x, Bold=1.1x,
Cheerful=1.2x) that auto-applies when selected. Voice picker now shows
persona description instead of accent/gender. Added expressive
punctuation guidance to the audio mode system prompt.

Progress bar is now tappable. Tapping at a position calculates the
character offset in the transcript, finds the nearest sentence boundary,
stops current playback, and re-speaks from that point. Elapsed timer
adjusts to the seek position. Only works for AI TTS bubbles (not
pre-recorded audio files).

Subject: [PATCH 049/223] fix: speed chip syncs with persona default speed from
 store

Speed display now reads directly from the store instead of local state,
so persona speed changes (0.9x, 1.1x, 1.2x) are reflected immediately.
Added persona speeds to the SPEED_STEPS cycle array. Speed chip cycling
handles custom speeds not in the step list by snapping to nearest.

Subject: [PATCH 050/223] fix: voice change crash, paused waveform, seekbar UX
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add 150ms delay between stop() and voice config change to let native
  ExecuTorch worker clean up — fixes SIGABRT crash on voice switch
- Stop waveform animation when paused (isThisAudible now checks !isPaused)
- Wider seekbar touch target (8px padding) with visible thumb dot
- Thicker progress track (4px) for easier tapping

Replaced separate progress bar with an inline seek area wrapping the
waveform bars. Tapping on the waveform area itself triggers seeking,
avoiding the play button touch conflict. Progress track + thumb dot
render directly below the waveform bars within the same touchable area.

Subject: [PATCH 054/223] fix: seekbar now uses onLayout width instead of
 measure()

measure() doesn't work reliably on Fabric. Use onLayout to capture the
waveform area width, then compute seek fraction from locationX directly.
Increased re-speak delay to 200ms for Kokoro cleanup.

Subject: [PATCH 055/223] fix: full-width seekbar with debug logs, separate
 from waveform

- Progress bar now spans the full bubble width as its own row
- Seekbar is a separate TouchableOpacity below the playback row,
  no longer nested inside the waveform area
- Added console.log in handleSeek and handleSeekBarTap for debugging
- 10px vertical padding on seekbar for easy tapping
- 12px thumb dot, 4px track height

Subject: [PATCH 057/223] fix: always wait 300ms after kokoroRef.stop() before
 new speak()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Seeking calls stop() then speak() — but Kokoro's native ExecuTorch
thread needs time to fully terminate. Previously only waited 80ms
and only when isSpeaking was true. Now always waits 300ms after
stop, fixing "model is currently generating" error during seek.

Subject: [PATCH 058/223] fix: seekbar position preserved across stop/speak
 cycle
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Seek sets a seekOffsetRef that survives the isThisAudible false→true
transition. The timer effect picks up the offset when playback restarts,
so the progress bar jumps to the seek position instead of resetting to 0.

KokoroTTSManager now uses a local activeVoiceId state that only updates
when isSpeaking is false. Changing voice in the store while speaking
queues the change — it applies automatically when playback stops.
This prevents the SIGABRT crash from reconfiguring useTextToSpeech
while the native ExecuTorch worker thread is still active.

Subject: [PATCH 062/223] fix: center seekbar dot, stop TTS on back navigation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Seekbar thumb dot now vertically centered on the progress track (top: 7)
- Added beforeRemove listener for back button navigation — more reliable
  than blur for native-stack navigator

Replace TouchableOpacity with PanResponder for the seekbar. Supports
both tap-to-seek and drag-to-seek. Thumb dot follows finger during
drag, then seeks to final position on release. Uses refs for stale
closure safety in PanResponder callbacks.

- Add react-native-executorch mock to jest.setup.ts (voice configs + useTextToSpeech)
- Fix tts integration test: speak() now passes callback as 3rd arg
- Update VoiceRecordButton tests: tap-to-toggle, download prompt, no "Transcribing..." text
- Update VoiceSettingsScreen tests: new UI with English/Multilingual sections, Active badge
- Update DownloadManagerScreen tests: conditional active section, filter bar touchables
- Update messageContent test: stripControlTokens now trims output

157 suites, 5181 tests, all passing.

Subject: [PATCH 070/223] refactor: replace custom PanResponder seekbar with
 native Slider
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use @react-native-community/slider (already installed) instead of
custom PanResponder-based seekbar. Native component handles drag
natively at 60fps — no JS thread bottleneck. Removes ~60 lines of
PanResponder/measure/layout tracking code. Added slider mock to
jest.setup.ts.

Replace animated WaveformBars (VU-meter, wave bounce, 3 animation modes,
Animated.Value refs) with simple static bars. Progress is now shown
entirely by the native Slider component. Remove RMS amplitude calculation
from KokoroTTSManager onNext callback. ~80 lines of animation code
removed. No more JS thread contention from per-chunk amplitude updates.

Subject: [PATCH 072/223] feat: word highlighting in transcript, stop TTS on
 record, fix multi-click play
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Transcript shows karaoke-style word highlighting based on playback
  progress — spoken words in full color, upcoming words muted
- Stop any TTS playback when user starts recording (mic + speaker
  shouldn't overlap)
- Set isSpeaking + currentMessageId immediately before the 300ms Kokoro
  cleanup wait, so UI shows loading state right away when switching clips

Subject: [PATCH 073/223] fix: voice change crash cooldown, single-word
 highlight with auto-scroll
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- KokoroTTSManager: 500ms cooldown after isSpeaking→false before applying
  voice config change, giving native ExecuTorch thread time to fully stop
- Transcript highlight: only the currently spoken word is highlighted
  (primary color + subtle background), not all spoken words
- Auto-scroll: ScrollView with maxHeight 120px, scrolls to keep the
  active word visible as playback progresses

Subject: [PATCH 074/223] fix: remove inaccurate word highlighting, add playing
 state visual
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove word-level transcript highlighting — Kokoro doesn't provide
  word timestamps, so it was always off. Keep transcript as plain text
  in a scrollable container (max 120px)
- Waveform bars now visually distinguish playing vs idle: playing bars
  are brighter (0.6–1.0 opacity), idle bars are dimmer (0.25–0.6)

Subject: [PATCH 075/223] feat: WhatsApp-style waveform progress + increase
 voice change cooldown
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Waveform bars now tint as the playhead passes: played bars are bright,
  unplayed bars are muted — like WhatsApp voice messages
- Progress is shown directly on the bars, with the Slider below for
  drag-to-seek interaction
- Increase voice change cooldown to 1500ms to prevent native crash

Subject: [PATCH 076/223] fix: consistent bubble widths, fixed-width audio
 bubble

- Audio bubble uses fixed width: 88% (not maxWidth) so it doesn't
  resize when transcript opens
- Thinking block wrapper matches at width: 88% (was maxWidth: 85%)
- Both bubbles now render at exactly the same width

Subject: [PATCH 077/223] feat: seekbar overlaid on waveform, visible on both
 user and AI bubbles
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Slider is now positioned on top of the waveform bars (centered
  vertically) instead of as a separate row below
- Slider track is transparent — waveform bar coloring shows progress
- Slider thumb (dot) sits on top of the waveform at the current position
- Seekbar visible on both user and AI audio bubbles
- Removed separate seekbar row — cleaner layout

Thumb is transparent when progress=0 and not seeking. Only becomes
visible (primary color) when audio is actively playing or user is
dragging the slider.

- Thumb always shows (primary color) so users know they can seek
- Expand seekOverlay to left/right -16px to compensate for Android
  Slider's built-in ~16px internal padding — thumb now aligns with
  the waveform bar highlighting

Subject: [PATCH 082/223] fix: tighter bars, bigger speed chip, 2s voice
 cooldown from stream end
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Increase to 48 bars with 1.5px gaps — fills full width, looks denser
- Bigger speed chip (more padding, larger border radius) — easier to tap
- Voice change cooldown now uses actual stream end timestamp instead of
  isSpeaking state — waits 2 seconds from when the native stream actually
  stopped, not from when JS flag flipped
- Both user and AI bubbles use same width: 88%

Subject: [PATCH 083/223] fix: waveform full bubble width, play button moved to
 meta row

Waveform bars now span edge-to-edge across the entire bubble width.
Play button sits in the meta row below alongside show transcript,
duration, and speed chip. No more asymmetric padding.

Reverted play button to left of waveform (standard layout). Reduced
playRow gap from SPACING.sm to SPACING.xs so waveform extends further
right.

Subject: [PATCH 090/223] fix: audio playback state races, voice switch crash,
 chat scroll & UI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Voice switch: key-based remount of KokoroTTSManager avoids native
  SIGSEGV when executorch re-initializes with a new voice config.
  Outer component manages cooldown, inner component holds the hook.
  Sets kokoroReady=false during switch so UI shows loader.

- Seekbar progress: playMessage finally block now checks ownership
  (currentMessageId === messageId) before clearing state, preventing
  it from clobbering an in-flight speak() call's isSpeaking/isAudioPlaying.
  Added playSessionId counter + retry loop (up to 10x 200ms) when
  executorch reports "model is currently generating" (code 104).

- Seekbar smoothness: timer interval 500ms→50ms, fractional seconds
  instead of Math.floor for continuous waveform bar progress.

- Transcript layout: split TranscriptSection into TranscriptToggle
  (stays in metaRow with time/speed) and TranscriptContent (renders
  below), preventing text from squeezing against duration/speed chip.

- Chat scroll: FlatList hidden (opacity:0) during initial layout,
  revealed after first scrollToEnd settles. Mode switch (chat↔audio)
  resets scroll via extraData + scrollToEnd.

- Voice loader UI: track kokoroActiveVoiceId in store, derive
  isChangingVoice in UI components from settings vs active mismatch.

Subject: [PATCH 092/223] fix: tool-call audio rendering, transcript scroll,
 action menu, conditional Kokoro

- Audio mode now renders tool-call messages via ChatMessage (proper
  bubble + tool call UI) instead of dropping them as raw unstyled text.
  Plain assistant messages still render as AudioMessageBubble.

- Transcript ScrollView uses react-native-gesture-handler for reliable
  nested scrolling inside FlatList on Android. Moved transcript outside
  the TouchableOpacity wrapper so it can capture scroll gestures.

- Action menu (long-press + 3-dot) added to both user and assistant
  audio bubbles: Copy + Resend for user, Copy + Regenerate for assistant.

- Kokoro TTS only loads in audio interface mode (App.tsx), saving RAM
  when in chat mode.

- Post-stream ownership transfer: when all text was spoken by streaming
  chunks, transfers currentMessageId from 'streaming' to the real
  message ID so the AudioMessageBubble seekbar works.

Subject: [PATCH 093/223] fix: stop TTS on retry/resend to prevent orphaned
 audio playback

When retrying a message while TTS is speaking, the audio bubble
disappears but Kokoro continues playing natively. Now calls
ttsStore.stop() before deleting messages in the retry handler.

Subject: [PATCH 094/223] revert: keep KokoroTTSManager always mounted
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Conditional mounting (audio mode only) caused Kokoro to not be ready
during streaming — it takes ~10s to initialize, but fast models finish
streaming before that. Streaming TTS chunks silently skipped because
kokoroReady was false. Reverting to always-mounted so Kokoro is warm
when streaming starts.

Subject: [PATCH 095/223] fix: drop streaming TTS chain, speak full response
 after streaming ends
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Streaming TTS chunks couldn't keep up with fast cloud models — Kokoro
speaks slower than tokens arrive, causing a growing backlog of unspoken
chunks, word skipping at transitions, and unpredictable playback.

Replaced with a simpler approach: text streams normally as a ChatMessage,
then when streaming ends the full response is spoken as a single TTS
call with the real message ID. Clean, predictable, no word skipping.

Also includes: stop in-flight TTS when new streaming begins, TTS stop
on retry/resend, and text offset fix for post-stream remaining calc.

Subject: [PATCH 096/223] feat: pluggable TTS engine interface with Kokoro +
 OuteTTS adapters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Introduce an engine abstraction layer that decouples the app from any
specific TTS implementation. Engines register with a generic registry,
the store delegates all operations through the active engine, and UI
components read engine-agnostic state.

- OnDeviceEngine base interface (lifecycle, assets, events, capabilities)
  designed to generalize to STT, Vision, and LLM modalities
- TTSEngine extends base with voice management, speak/stop/pause/resume,
  generateAndSave, and streaming audio events
- KokoroEngine wraps react-native-executorch hook via bridge component
- OuteTTSEngine absorbs ttsService.ts into the engine interface
- Qwen3TTSEngine stub with asset management ready, inference pipeline TODO
- ttsStore rewritten as thin proxy — no engine-specific branching
- Engine picker added to TTS Settings screen
- Settings migration from old voiceId/kokoroVoiceId to voiceByEngine map
- Race condition fixes via playSessionId ownership
- 157 test suites, 5176 tests passing, 0 tsc errors, 0 lint errors

+# TTS Engine Interface
+
+## Overview
+
+The TTS subsystem uses a pluggable engine interface that decouples the app from any specific TTS implementation. Engines are registered at startup, the user picks one in settings, and the store delegates all operations through the active engine.
+
+The interface is designed as the first concrete implementation of a broader **On-Device Engine** pattern that will generalize to STT, Vision, and LLM modalities.
+
+## Architecture
+
+```
+src/engine/
+  types.ts                 # OnDeviceEngine base + TTSEngine interface
+  OnDeviceEngineEmitter.ts # Zero-dep typed event emitter
+  EngineRegistry.ts        # Generic registry (TTS, STT, Vision, LLM)
+  index.ts                 # Barrel + singleton ttsRegistry
+
+  tts/engines/
+    kokoro/                # Kokoro TTS via react-native-executorch
+      KokoroEngine.ts      # TTSEngine implementation
+      KokoroTTSBridge.tsx  # React component bridge (wraps useTextToSpeech hook)
+      voices.ts            # 8 voice definitions
+    outetts/               # OuteTTS 0.3 via llama.rn
+      OuteTTSEngine.ts     # TTSEngine implementation
+      models.ts            # GGUF asset definitions
+    qwen3/                 # Qwen3-TTS 0.6B (stub)
+      Qwen3TTSEngine.ts    # Asset management ready, inference TODO
+      models.ts            # Talker + predictor + codec asset definitions
+```
+
+## How It Works
+
+### Engine Lifecycle
+
+```
+register → getEngine → setActiveEngine → initialize → speak/stop/pause → release
+```
+
+1. **Registration** — engines register factories at import time in `engine/index.ts`
+2. **Activation** — `ttsRegistry.setActiveEngine('kokoro')` creates the instance and releases the previous engine
+3. **Initialization** — imperative engines (OuteTTS) load models via `initialize()`. Hook-based engines (Kokoro) initialize when the bridge component mounts.
+4. **Usage** — `engine.speak(text, options)` is the universal entry point
+5. **Teardown** — `engine.release()` frees models; `engine.destroy()` also deletes downloaded files
+
+### Event System
+
+Every engine emits typed events. The store subscribes once and syncs state:
+
+- `phaseChange` — idle/downloading/loading/ready/processing/paused/error
+- `audioChunk` — streaming PCM data (Kokoro)
+- `audioComplete` — full audio buffer (OuteTTS)
+- `downloadProgress` — per-asset download progress
+- `amplitudeChange` — RMS amplitude for waveform visualization
+- `voiceChanged` — active voice updated
+- `error` — recoverable/non-recoverable errors
+
+### Store Delegation
+
+The Zustand store (`ttsStore.ts`) is a thin proxy:
+
+```typescript
+speak: async (text, messageId) => {
+  const engine = ttsRegistry.getActiveEngine();
+  if (!engine || !get().settings.enabled) return;
+  await engine.speak(text, { speed: get().settings.speed, messageId });
+}
+```
+
+No engine-specific branching. The store exposes derived booleans (`isReady`, `isSpeaking`, `isPaused`) computed from the engine's phase for backward compatibility with UI components.
+
+### React Bridge Pattern
+
+Some engines (Kokoro) depend on React hooks. These engines return a React component from `getBridgeComponent()`. The `<EngineBridge />` component (mounted in `App.tsx`) renders it:
+
+```
+App.tsx → <EngineBridge /> → engine.getBridgeComponent() → <KokoroTTSBridge />
+```
+
+The bridge mounts the hook, then pushes an imperative handle into the engine instance. Fully imperative engines (OuteTTS, Qwen3) return `null` — no bridge needed.
+
+## Registered Engines
+
+| Engine | ID | Size | Streaming | Voice Cloning | Status |
+|--------|-----|------|-----------|---------------|--------|
+| Kokoro TTS | `kokoro` | 82 MB | Yes | No | Production |
+| OuteTTS 0.3 | `outetts` | 530 MB | No | Yes | Production |
+| Qwen3-TTS 0.6B | `qwen3-tts` | ~650 MB | No | Yes | Stub (not registered) |
+
+## Adding a New Engine
+
+1. Create `src/engine/tts/engines/<name>/` with:
+   - `models.ts` — `ModelAsset[]` definitions (URLs, sizes, filenames)
+   - `<Name>Engine.ts` — class extending `OnDeviceEngineEmitter<TTSEngineEvents>` implementing `TTSEngine`
+   - `index.ts` — barrel exports
+
+2. Implement the interface:
+   - `getRequiredAssets()` — what to download
+   - `initialize()` — load models into memory
+   - `speak()` — text in, audio out
+   - `getVoices()` / `setVoice()` — voice management
+   - `stop()` / `pause()` / `resume()` — playback control
+   - `getBridgeComponent()` — return `null` for imperative engines
+
+3. Register in `src/engine/index.ts`:
+   ```typescript
+   import { MyEngine } from './tts/engines/myengine';
+   ttsRegistry.register('myengine', () => new MyEngine());
+   ```
+
+4. It appears in the engine picker on the TTS Settings screen automatically.
+
+## Multimodal Future
+
+The `OnDeviceEngine` base interface generalizes beyond TTS:
+
+```
+OnDeviceEngine<TEvents>        # lifecycle, assets, events, capabilities
+  ├── TTSEngine                # text → audio (Kokoro, OuteTTS, Qwen3)
+  ├── STTEngine (future)       # audio → text (whisper.rn)
+  ├── VisionEngine (future)    # image → structured (CoreML)
+  └── LLMEngine (future)       # text → text (llama.rn)
+```
+
+Each modality shares: lifecycle management, model asset download/delete, typed event system, capability declaration, platform checks, and the React bridge pattern.
+
+The `EngineRegistry<T>` is generic — `new EngineRegistry<STTEngine>()` works identically.
+
+The orchestration layer above would wire engines together:
+- **Listen** (STT) → **Think** (LLM) → **Speak** (TTS)
+- **See** (Vision) feeds context to **Think**
+
+## Qwen3-TTS Integration Path
+
+The stub is ready at `src/engine/tts/engines/qwen3/`. Asset management, download, and lifecycle are implemented. The remaining work is the inference pipeline in `speak()`:
+
+1. Load talker GGUF + predictor GGUF via `llama.rn` (two contexts)
+2. Load codec decoder ONNX via `onnxruntime-react-native`
+3. Talker generates first-codebook tokens at 12Hz
+4. Predictor fills codebooks 2-16
+5. Codec decodes token grid to PCM Float32 at 24kHz
+
+Reference: [LunaVox](https://github.com/wkwong/lunavox) has a working desktop implementation of this pipeline.
+
+## Settings Migration
+
+The store handles migration from the pre-engine-interface format automatically via `onRehydrateStorage`. Old fields (`voiceId`, `kokoroVoiceId`) are migrated to `voiceByEngine` map on first load.
+
+## Key Files
+
+- `src/engine/types.ts` — all interfaces
+- `src/engine/index.ts` — registry + engine registration
+- `src/stores/ttsStore.ts` — store (delegates to active engine)
+- `src/components/EngineBridge.tsx` — renders bridge for hook-based engines
+- `src/screens/TTSSettingsScreen/index.tsx` — engine picker UI

+ *   3. Codec decoder (ONNX) — converts token grid to PCM audio waveform
+ *
+ * The talker and predictor run via llama.rn (GGUF).
+ * The codec decoder runs via ONNX Runtime (onnxruntime-react-native).
+ *
+ * 12Hz frame rate = dramatically fewer tokens per second of audio than
+ * OuteTTS (75Hz) or most other TTS models. This makes on-device inference
+ * much more feasible.
+ *
+ * STATUS: Stub — asset management and lifecycle are wired up; the actual

Subject: [PATCH 103/223] fix: map @offgrid/core/* in tsconfig so tsc resolves
 the pro extension

The EmailCalendarExtension test imports the pro module by path, pulling it
into tsc's program past the pro/** exclude. Without a paths mapping for
@offgrid/core/* (which jest.config.js already has), tsc could not resolve
the pro module's core type imports, cascading into TS18046/TS7006 errors.
Mirror the jest moduleNameMapper so tsc and jest agree.

Subject: [PATCH 104/223] fix: make CI green without the private pro submodule

Two CI-only failures (both pass locally where the pro submodule is checked
out and revenueCatKeys.ts has the full local copy):

- revenueCatKeys.ts committed an older placeholder missing RC_WEB_PURCHASE_URL,
  which proLicenseService imports. Add the (public, safe-to-commit) web purchase
  URL placeholder so the committed config exports every symbol the app uses.
- EmailCalendarExtension.test.ts imported the pro module by a static path that
  tsc/jest cannot resolve when pro/ is absent (open-core CI does not check out
  the private submodule). Load it via a computed-path require and skip the suite
  when missing; it still runs locally and in the pro repo CI.

Subject: [PATCH 105/223] feat: pro unlock modal polish (dismiss, border,
 input-gated CTA)

- Success card gets a 'Got it' button (and onRequestClose) so the user
  can read the activation message and dismiss it, instead of being
  trapped with no way out but force-killing the app.
- Card now has a visible border (colors.border) so it reads in dark
  mode, where the shadow alone disappeared against the background.
- CTA (Continue to payment / Verify and unlock) is enabled only once
  non-whitespace text is entered; no format validation. Whitespace is
  stripped before use, matching the service-layer trim/lowercase.
- Drop the stale RNRestart comment in ProDetailScreen (the lib was
  removed); Pro now loads on next launch via checkProStatus.
- Tests updated for the disabled-until-typed CTA, whitespace handling,
  and the success-card dismiss.

Subject: [PATCH 106/223] chore: bump pro submodule for MCP screen fixes

Points the pro gitlink at af5aa10 (offgrid-pro feat/email-calendar-tools)
which includes the MCP servers screen header inset fix, removal of the
demo-servers link, and the now-required server name field.

Subject: [PATCH 107/223] refactor: move audio/TTS mode into the pro submodule
 behind a slot/hook seam
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Audio mode is now a pro feature: all TTS/voice-output code lives in the
private @offgrid/pro package (pro/audio/) and is injected into core at
runtime, so the free build compiles and runs with audio absent.

Core seam additions:
- bootstrap/slotRegistry.ts (registerSlot/getSlot) and hookRegistry.ts
  (registerHook/getHook/callHook) — pro fills named UI slots + behaviour
  hooks during activate(); empty/no-op without pro.
- stores/uiModeStore.ts — reactive interface-mode flag ('chat'|'audio') that
  pro mirrors into, so core reacts without importing pro.
- loadProFeatures passes registerSlot/registerHook to pro.activate(), and a
  __DEV__-only DEV_UNLOCK_PRO force-activates pro on dev builds (never in
  release). App.tsx also marks dev builds as registered-Pro.

Rewired core integration points to the seam (App root engine bridge,
chat-input audio layout, audio message bubbles, per-message speak button,
quick-settings voice toggle, generation-settings TTS section, prompt
augmentation, streaming-end speech, app-background pause). Voice INPUT
(recording, Whisper STT, VoiceRecordButton) stays public.

Deleted the now-relocated audio sources from src/ (engine, ttsStore,
ttsService, tts types, kokoro/tts constants, useTTS, TTSSettingsScreen,
AudioMessageBubble, TTSButton, EngineBridge, AudioModeLayout, TTSSection)
and bumped the pro submodule to the audio-mode commit.

Public tsc + eslint clean; 5555 tests pass; free-build invariant holds.

- * Qwen3TTSEngine — TTSEngine stub for Qwen3-TTS.

- *   2. Predictor (GGUF) — fills parallel codebook tracks (16 codebooks)
- *   3. Codec decoder (ONNX) — converts token grid to PCM audio waveform
- *
- * The talker and predictor run via llama.rn (GGUF).
- * The codec decoder runs via ONNX Runtime (onnxruntime-react-native).
- *
- * 12Hz frame rate = dramatically fewer tokens per second of audio than
- * OuteTTS (75Hz) or most other TTS models. This makes on-device inference
- * much more feasible.
- *
- * STATUS: Stub — asset management and lifecycle are wired up; the actual
- * inference pipeline is TODO pending integration testing.

Subject: [PATCH 108/223] fix(boot): isolate RevenueCat init so Pro features
 load when billing is unavailable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

App init previously wrapped configureRevenueCat()/checkProStatus() and
loadProFeatures() in the same try block. On emulators and any device
without Play billing, RevenueCat throws InvalidCredentialsError /
BILLING_UNAVAILABLE, which aborted the block before loadProFeatures()
ever ran — so the @offgrid/pro submodule never activated and audio mode
/ MCP / TTS stayed hidden even in dev builds.

Split RevenueCat into its own try block that only logs on failure and
records the entitlement (defaulting to false). loadProFeatures(isPro)
then runs unconditionally; in dev it force-unlocks Pro and sets
setHasRegisteredPro(true) so the registry-seam pro UI renders.

Verified on Android emulator: RevenueCat fails as expected
("keeping cached state") yet the app shows Pro Active with Voice
(audio mode), Calendar, Email, Messaging, and MCP Access.

Subject: [PATCH 109/223] test(tts): cover Kokoro on-disk install-status
 detection

Adds a virtual mock for react-native-executorch-bare-resource-fetcher and
makes the executorch KOKORO_MEDIUM mock match the real object shape, then
adds KokoroEngine tests for the install-status fix: disk-derived
'downloaded', partial cache, the engine-switch regression (stays
downloaded after the bridge unmounts), voice-switch progress reset,
fetcher-failure resilience, and deleteAssets.

Subject: [PATCH 110/223] feat(chat-input): inline Chat/Audio toggle slot + fix
 clipped pill icons

Adds the chatInput.modeToggle slot and renders it in the input pill row
(empty in free builds). Pro fills it with a one-tap interface toggle.

Also fixes a pre-existing layout bug: the pill-icons row used a fixed
2-icon width with overflow:hidden, so the settings gear was already
clipped on thinking-capable models and the new toggle would be too. The
row now sizes to the actual icon count via computePillIconsWidth().

Subject: [PATCH 111/223] fix(chat): stop stacking bottom safe-area below the
 chat input
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The chat screen applied edges={['top','bottom']} AND the input had its own
paddingBottom, so the safe-area inset stacked on top — leaving a visible
gap below the bar (worse on Android gesture-nav). The input footer now
owns the bottom inset (max(insets.bottom - basePad, 0)) and collapses it
while the keyboard is open; the screen uses edges={['top']} only. No
Platform.OS layout branching, so it is correct on iOS and Android by
construction. Adds a reusable useKeyboardVisible hook.

Subject: [PATCH 112/223] feat(models): add Voice Models tab with pro panel +
 non-pro upsell

Add a third "Voice Models" tab to the Models screen alongside Text and
Image. The tab always renders; pro fills the modelsScreen.voiceTab slot
with the real engine/download panel, and free / non-pro builds show a
VoiceModelsUpsell teaser (on-device TTS pitch + Get Pro -> ProDetail).

- New core slot modelsScreen.voiceTab.
- ModelTab gains 'voice'; ModelsTab route initialTab accepts 'voice'.
- Tests: Voice tab always visible, upsell shown without pro, Get Pro
  navigates to ProDetail; VoiceModelsPanel card/download/activate flow.

Bumps the pro submodule to the matching Voice Models panel commit.

Subject: [PATCH 113/223] fix(downloads): collapse TTS/STT chips into one Voice
 Models filter

The Download Manager had separate "Text to Speech" and "Speech to Text"
filter chips. Merge them into a single "Voice Models" chip that matches
either modelType, matching the Voice Models tab naming.

Also bumps the pro submodule (Voice Models card styling fix) and updates
the VoiceModelsPanel test for the simplified clickable-card behaviour.

Subject: [PATCH 114/223] feat(models): add Transcription Models
 (speech-to-text) tab

Add a fourth "Transcription Models" tab next to Voice Models for on-device
speech-to-text (Whisper). It shows the built-in ggml catalogue (English +
multilingual) as ModelCards and a HuggingFace search so users can find
other-language / community fine-tuned ggml whisper models, downloaded via
the existing whisper service. Whisper is core, so the tab is always shown
(no pro gating).

The Models tab bar is now horizontally scrollable so four tabs fit on a
phone without clipping.

Subject: [PATCH 115/223] feat(downloads): show voice + transcription models in
 Download Manager

Downloaded voice (TTS) and transcription (STT/Whisper) models never
appeared in the Download Manager because its completed list was built only
from the text/image model stores. They now show up:

- whisperService.listDownloadedModels() reads downloaded ggml files on disk.
- New useVoiceDownloadItems hook merges STT (core) + TTS (pro, via the
  downloads.listVoiceModels hook) into completedItems as modelType
  tts/stt, and routes their deletes to the right service.
- The existing text/image item mapping is extracted to a module helper to
  keep useDownloadManager under the line budget.

Bumps the pro submodule (registers the voice-models download hooks).

Subject: [PATCH 117/223] test(audio): cover GGUF download reroute +
 partial-file fix

Add OuteTTSEngine download tests: routes through the shared background
download engine, falls back to RNFS when unavailable, treats truncated
on-disk files as not-downloaded, and rejects/cleans up incomplete
downloads. Bumps the pro submodule to the rerouted engines.

Subject: [PATCH 118/223] fix(models): reuse shared search styling in
 Transcription tab

The Transcription tab had a custom search bar (icon + border) that looked
different from the Text/Image tabs. Reuse the Models screen's shared
searchContainer/searchInput styles (and deviceBanner) so the search field
is identical across all model tabs.

+## Reuse Before Building
+
+**Before writing any new component, style, hook, or service, search for an existing one and reuse it.** Building a parallel version of something that already exists creates visual and behavioural drift (e.g. a search box that looks different from every other search box).
+
+- For UI: grep `src/components/` and the relevant screen folder for an existing component or shared style (e.g. `ModelCard`, `Card`, `Button`, shared `searchContainer`/`searchInput` styles) before creating your own. Two screens that show the same kind of thing must use the same component.
+- For logic: check for an existing hook/service/store action (`grep -rn`) before adding a new one.
+- If an existing component is close but not exact, extend it with a prop rather than forking a copy.
+- Only build new when nothing fits — and say so in the PR description.

+# Model Routing & Orchestration — Design Plan
+
+Status: **proposal, for review** · Owner: TBD · Last updated: 2026-06-20
+
+## 1. Problem
+
+A user can have several on-device models installed across different jobs:
+text-to-text (llama GGUF), text-to-image (diffusion), speech-to-text
+(Whisper), and text-to-speech (pro TTS engines). Today the user must manually
+pick the active model, and a chat effectively assumes a text model is loaded.
+
+We want: **the user types (or speaks) a request, and the app figures out which
+model is needed, loads it if it isn't already, and runs it** — without the user
+hand-selecting a model first. First load of a model is slow; subsequent uses are
+fast (warm).
+
+## 2. The key distinction (read this first)
+
+The "4 models" are not 4 interchangeable routing destinations. They split on two
+axes:
+
+| Axis | Models | Role |
+|---|---|---|
+| **Generation target** (what produces the answer) | text-to-text, text-to-image | A prompt is *routed to* one of these. |
+| **I/O modality** (how input/output is carried) | STT (speech in), TTS (speech out) | Layered around a turn — not a destination. |
+
+So the routable decision per turn is **text vs image**. STT just turns a
+voice note into the prompt text *before* routing; TTS just speaks the result
+*after*. This matters because it keeps the router small and correct: one
+classifier (text vs image), not a 4-way switch.
+
+```
+                 ┌──────────── optional STT (mic) ───────────┐
+   voice input ──┤                                            │
+                 └──> prompt text ──> [ROUTER: text|image] ──> generation
+   typed input ─────> prompt text ──┘                           │
+                                                                 ▼
+                                              text answer ──> optional TTS (speak)
+```
+
+## 3. What already exists (reuse, don't rebuild)
+
+- **`intentClassifier`** (`src/services/intentClassifier.ts`): classifies a
+  message as `text | image`. Two modes — fast keyword heuristics, or an LLM
+  classifier model (`settings.classifierModelId`). It **already hot-swaps** to
+  the classifier model and remembers the original.
+- **`activeModelService`**: `loadTextModel(id)`, `getActiveModels()`,
+  `unloadImageModel()` — the model lifecycle singleton.
+- **`llmService`**: `getLoadedModelPath()`, `isModelLoaded()`,
+  `generateResponse()` — one text context at a time.
+- **`whisperStore`** (STT): `downloadedModelId`, `loadModel()`,
+  `unloadModel()` — currently a single active model.
+- **pro `ttsStore` / engine registry** (TTS): `isReady`, `setEngine`,
+  `initializeEngine()`.
+- **`settings.modelLoadingStrategy`**: existing knob for eager/lazy loading.
+- Chat already supports an **image-only path** (`hasActiveModel = text || image`,
+  `shouldRouteToImageGenerationFn` returns image when no text model).
+
+**Conclusion:** ~70% of the primitives exist. The work is an orchestration layer
+on top, plus a memory/eviction policy, not a from-scratch system.
+
+## 4. The hard constraint: memory
+
+You cannot hold a text LLM + a diffusion model + Whisper + a TTS engine in RAM
+simultaneously on a phone. "Everything hot" is not achievable. So:
+
+- **At most one generation model resident at a time** (text *or* image).
+- Whisper and a TTS engine are smaller and may co-reside with a generation
+  model on higher-RAM devices, but must be evictable.
+- "Hot loading" therefore means **load-on-demand + evict-the-previous**, with the
+  OS file cache making the *second* load of a given model fast. First load is
+  slow — accepted and surfaced with a loading state.
+
+This makes an explicit **memory budget + eviction policy** the core of the
+design, not the classifier.
+
+## 5. Proposed architecture
+
+### 5.1 `modelOrchestrator` (new service, core)
+
+A single entry point the chat send-path calls instead of assuming a loaded model.
+
+```
+orchestrateTurn({ promptText, forceTarget?, ramBudgetMB }) →
+  1. target = forceTarget ?? classify(promptText)        // 'text' | 'image'
+  2. ensureResident(target)                               // load if cold, evict others
+  3. return a handle the caller runs generation against
+```
+
+Responsibilities:
+- Decide the target (delegates to `intentClassifier`).
+- Ensure the target model is resident (delegates to `activeModelService`).
+- Enforce the memory budget by unloading what's not needed.
+
+### 5.2 Residency manager (memory budget + eviction)
+
+- Track what's loaded (`activeModelService.getActiveModels()` + whisper + tts).
+- A simple policy to start: **one resident generation model**; loading text
+  unloads image and vice-versa. Whisper/TTS load on use, unload on memory
+  pressure or when idle.
+- LRU eviction when a new load would exceed the device RAM budget
+  (`hardwareService.getTotalMemoryGB()` → budget). Log every evict (no silent
+  drops).
+- Future: keep a tiny classifier model pinned (see 5.3).
+
+### 5.3 The classifier (avoid "load a model just to choose a model")
+
+Loading a 1GB LLM only to decide "text vs image" defeats the purpose. So:
+- **Default: heuristics-first** (the keyword classifier already exists, ~instant,
+  no load). Route on that unless ambiguous.
+- **Optional LLM classifier**: only when the user opts in *and* a small
+  classifier model is downloaded. Ideally a tiny (<300MB) model kept pinned so
+  classification never triggers a big swap. If not pinned, classification reuses
+  the already-loaded text model when there is one.
+- Cache decisions per prompt (already done via `intentCache`).
+
+### 5.4 STT / TTS integration (modalities)
+
+- **STT**: the mic button transcribes with the active Whisper model, then feeds
+  the text into `orchestrateTurn`. Active-Whisper selection is its own small
+  feature (see §7) — independent of routing.
+- **TTS**: unchanged audio-mode toggle; speaks the final text answer. The
+  orchestrator does not route to TTS; the audio-mode hook does.
+
+## 6. Routing decision flow (per turn)
+
+1. Input arrives (typed, or STT-transcribed voice note).
+2. `forceTarget`? (explicit image button / image-only because no text model) →
+   skip classify.
+3. Else classify text vs image (heuristics, or opt-in LLM).
+4. `ensureResident(target)`: if cold, show "Loading <model>…", evict as needed,
+   load. If warm, proceed instantly.
+5. Run generation; stream result.
+6. If audio mode on and target was text → TTS speaks it.
+
+## 7. Phasing (each phase shippable on its own)
+
+- **Phase 0 — Active model selection (prereq, small).**
+  Let users pick the active Whisper model among several downloaded (track
+  multiple ids, tap-to-activate in the Transcription tab). Same for confirming
+  text/image active selection is coherent. No routing yet.
+- **Phase 1 — Auto-load the routed generation model.**
+  On send, classify (heuristics) → if the needed gen model isn't resident, load
+  it (evicting the other) with a visible loading state. Removes manual
+  pre-selection for text↔image. Reuses `intentClassifier` + `activeModelService`.
+- **Phase 2 — Residency manager + memory budget.**
+  Formalize the budget + LRU eviction across text/image/whisper/tts. Instrument
+  loads/evicts. Handle low-RAM devices gracefully.
+- **Phase 3 — Pinned tiny classifier (optional).**
+  Allow a small always-resident classifier for higher-accuracy routing without a
+  big-model swap. Opt-in in settings.
+- **Phase 4 — Polish.**
+  Pre-warm prediction (load the likely-next model during idle), per-conversation
+  sticky target, telemetry on misroutes.
+
+## 8. Risks / open questions
+
+- **Misclassification** routes to the wrong (and slow-to-load) model. Mitigate:
+  heuristics-first, a manual override chip, decision cache, easy "switch to
+  text/image" affordance.
+- **Load latency** on first use (multi-GB models). Mitigate: clear loading UI,
+  pre-warm in Phase 4.
+- **Memory thrash** if the user alternates text/image every turn (constant
+  load/evict). Mitigate: sticky target per conversation; only swap on a
+  confident classification.
+- **Whisper multi-model state** needs a small refactor (single → many).
+- **iOS vs Android** native load/unload behaviour must be verified equally.
+
+## 9. Testing
+
+- Unit: orchestrator decision table (forceTarget, cold/warm, image-only).
+- Unit: residency/eviction policy under a fake RAM budget.
+- Integration: STT → orchestrate → generate → TTS end-to-end with mocked
+  native layers.
+- Device: real first-load vs warm-load timings; alternating text/image; low-RAM
+  device behaviour.
+
+## 10. Recommendation
+
+Build **Phase 0 then Phase 1** first — they remove the "must pre-select a model"
+friction with low risk and reuse existing services. Treat Phases 2–4 as a
+follow-up once the load-on-demand UX is proven on-device.

 on multiple models
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- §5.3: default classifier is SmolLM2-135M-Instruct (~100MB, runs on the
  existing llama.rn runtime, kept pinned/reserved in the budget);
  heuristics-first; all-MiniLM-L6-v2 (embeddings) noted as the better-per-MB
  upgrade if a small embeddings runtime is ever added.
- §6: routing + the classifier only run when 2+ generation models are
  available; a single model is used directly with zero overhead.

Subject: [PATCH 121/223] feat(routing): add model residency manager (memory
 budget + eviction)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Core of model routing's memory guarantee (docs/design/MODEL_ROUTING.md
§5.1-5.2): keep only what's needed resident in RAM.

- policy.ts (pure): computeBudgetMB derives a RAM budget from device memory
  (min of 60% and total-minus-1.5GB headroom); planEviction picks victims so
  an incoming model fits - generation models (text/image) are mutually
  exclusive, pinned models (the ~100MB SMOL classifier) are never evicted,
  otherwise LRU.
- index.ts: ModelResidencyManager.ensureResident(spec, {load, unload}) runs
  the plan, unloads victims, then loads the target; register() accounts for
  already-loaded/pinned models; evictAll() for memory warnings. Load/unload
  are injected, so it's decoupled from the text/image/whisper/tts services
  and unit-testable.

Not yet wired into the live send path (next step). 11 unit tests cover the
budget math, mutual exclusion, pinned protection, LRU, and the manager.

Subject: [PATCH 122/223] feat(image): disable prompt enhancement when no text
 model is available

"Enhance Image Prompts" runs the prompt through a text model, so it can't
work without one. Both toggles (Model Settings + the generation settings
modal) are now disabled and dimmed with a "Download a text model to enable"
hint when no text model is downloaded. The generation service already skips
enhancement when no text model is loaded, so this is the matching UI gate.

Tests updated to seed a text model where the enabled state is asserted, plus
a new test for the disabled-without-text-model case.

Subject: [PATCH 123/223] feat(routing): make residency manager authoritative
 for model memory

Route text + image model loads through modelResidencyManager so memory is
managed by a single budget (docs/design/MODEL_ROUTING.md), overriding the
old hardcoded "<=4GB unloads text" logic:

- activeModelService load paths call makeRoomFor() to evict (LRU, by
  estimated runtime RAM) and fit the device budget before loading, register
  the model on load, and release on unload.
- The old per-load critical-memory gate is replaced by the residency
  budget: a model that can't fit even after eviction is blocked.
- Policy is budget-driven, not hard mutual-exclusion: a high-RAM device can
  keep a text + image model co-resident if they fit; a constrained device
  evicts to make room. makeRoomFor reports whether the model fits.

Tests updated for the budget-driven behaviour (co-resident when it fits,
evict/block when it doesn't); residency manager beforeEach reset added.

Subject: [PATCH 124/223] refactor(models): remove the modelLoadingStrategy
 (fast/optimised) setting

The fast/optimised swap-strategy setting is obsolete now the residency
manager owns model swapping (docs/design/MODEL_ROUTING.md). Remove it
everywhere:

- appStore: drop the setting + default; rehydrate strips it from old
  persisted state.
- ModelLoadingStrategy type removed.
- intentClassifier: always restore the original text model after
  classifying (the residency manager fits it back into memory); the
  "memory mode keeps classifier loaded" branch is gone.
- Remove both UI toggles (Model Settings + generation settings modal) and
  the chat preload's strategy gate.

Tests updated/removed accordingly.

Subject: [PATCH 125/223] feat(routing): remember last text model + preload it
 on chat open

- appStore.lastTextModelId: persisted preference set when the user picks a
  text model (in useModelLoading). Unlike activeModelId it is not cleared
  when the residency manager evicts the model, so routing can reload it on
  demand.
- ChatScreen preloads lastTextModelId in the background on open (when no
  generation model is already loaded), so the user can start typing while
  it loads.

Foundation for on-demand text-model routing (next: classify + load/select).

Subject: [PATCH 126/223] feat(routing): differentiate text vs image + load
 text model on demand

When the chat has only an image model (or none) loaded and the user sends a
message, it now classifies the request and routes correctly instead of
always generating an image:

- shouldRouteToImageGenerationFn classifies by fast heuristics when no text
  model is loaded (a chat request returns false instead of forcing image).
- handleSendFn: for a chat request with no text model, ensureTextModelForChat
  loads the last-selected text model (residency evicts the image model to
  fit) or opens the model selector when none was ever chosen.
- startGenerationFn routes by live model state (llmService.isModelLoaded), so
  a model loaded mid-send generates text rather than mis-routing to image.
- ChatMessageArea shows a "Loading <model>" bar above the input while the
  model loads (also covers the chat-open background preload).

Tests cover heuristic routing with no text model and the load-or-select branch.

Subject: [PATCH 127/223] feat(routing): use the SMOL LLM classifier for
 image-only routing

When no text model is loaded, route text-vs-image with the configured
classifier model (SmolLM2) via the LLM intent classifier for real
intelligence, instead of keyword heuristics. Falls back to heuristics only
when no classifier model is downloaded. Shows the "Understanding your
request..." bar while classifying.

The classifier loads through activeModelService, so the residency manager
accounts for it; with llama.rn's single context it can't be pinned
separately from the main text model, so it stays loaded until a text model
is needed.

Subject: [PATCH 128/223] feat(routing): auto-provision the default SmolLM2
 classifier

So LLM routing works out of the box: when image-only routing needs a
classifier but none is configured, download SmolLM2-135M-Instruct (~100-145MB)
in the background via the normal text-model path (visible in the Download
Manager) and select it as settings.classifierModelId on completion. Fetches
the GGUF from HuggingFace dynamically (prefers Q8_0) so it's robust to exact
filenames. Heuristics handle that first turn; subsequent turns use the SMOL
model. Guarded against duplicate downloads and no-ops once a classifier is set.

Subject: [PATCH 129/223] test(pro): fix pro-boot entitlement gating tests
 under __DEV__

DEV_UNLOCK_PRO = __DEV__, which is true in jest, so loadProFeatures always
activated Pro and the "no activation without entitlement" assertions failed.
Set __DEV__ = false in these suites (restored after) so they exercise the
production gating they're meant to verify. Full suite now green.

Subject: [PATCH 130/223] fix(chat): load models inline, no full-screen
 takeover
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The chat showed a full-screen LoadingScreen whenever a model was loading,
replacing the conversation. Remove it so the chat stays visible and model
loading is shown inline via the "Loading model" bar above the input (the
image model already loaded inline). Bumps pro (voice-model spinner).

Fixes a test that passed vacuously because the full-screen loading hid the
chat body (its loadedSettings was incomplete, so hasPendingSettings was
actually true) — now loadedSettings matches the full settings.

Subject: [PATCH 131/223] feat(routing): warm selected models at boot (text ->
 image -> TTS -> STT)

Kill the cold-start wait: on launch, preload the user's selected models in
priority order, in the background, sequentially (one native load at a time so
the UI stays responsive).

- modelResidency.canLoadWithoutEviction: a model is preloaded only if it fits
  the RAM budget without evicting a higher-priority one already warmed, so it
  self-limits on small devices (text always wins; the rest fill the remainder).
- modelPreloader walks text/image/STT (and TTS via the audio.preload hook),
  loading each only if available + fits + not already loaded.
- whisperStore registers the STT model with the residency manager on load so
  the budget accounts for it.
- App boot fires preloadSelectedModels() after the UI is shown (fire-and-forget).

Bumps pro (audio.preload hook). Tests cover the fits check, priority ordering,
skip-on-no-fit, run-once, and the empty case.

Subject: [PATCH 132/223] fix(routing): don't lose the message when the model
 selector opens

When a chat request arrived with no text model, routing opened the model
selector but dropped the message (the input had already cleared), forcing a
retype. Now the message is stashed when the selector opens and replayed
automatically once the user picks a text model.

- handleSendFn calls setPendingMessage(text, attachments) before aborting.
- useChatScreen.handleModelSelect replays the stashed message after the model
  loads, then clears it.

Subject: [PATCH 134/223] feat(audio): wire streaming TTS + chat-mode
 select-text; bump pro

- new audio.onStreamingToken hook fired from chatStore streaming sink; pro
  consumes it for real-time sentence-by-sentence TTS.
- chat-mode "Select text" action: long-press menu opens a selectable sheet for
  partial copy (gated to chat mode; audio bubbles unaffected).
- bump pro submodule (streaming TTS, unified playback, live speed, no-text
  audio mode, select-text-free transcript handling).
- accumulated session work: model routing/residency, warm preload, hardware
  SoC/NPU detection, generation service, RAG embedding.

+## Architecture & Abstractions (SOLID)
+
+**Design to abstractions, not concrete implementations.** When there are multiple interchangeable implementations of a thing (TTS engines, model backends, providers, storage), the rest of the app must depend on a single interface/service layer — never branch on a concrete type.
+
+- **No leaking implementation details upward.** UI and stores must not do `instanceof SpecificEngine`, check `engineId === 'kokoro'`, or branch on capabilities to decide *how* to do something. Push that decision behind the abstraction (the engine/provider implements it; or a service layer dispatches once). If you find yourself writing `if (engine X) … else …` in a component, the abstraction is wrong.
+- **Single uniform entry point.** Prefer one polymorphic method (e.g. `engine.play(text, opts)`) that every implementation satisfies over several mechanism-specific methods (`speak` vs `playFromFile`) that callers must choose between.
+- **Service layer between UI and implementations.** Implementations (engines/adapters) are swappable; a service abstracts them and exposes a normalized API + state. Adding a new implementation must require zero changes to UI/store.
+- **Dependency Inversion / Liskov:** any implementation must be substitutable through the interface without callers knowing which one is active. Normalize gaps (e.g. an engine that can't report playback position) inside the service, not in the UI.
+- Apply the rest of SOLID: single responsibility per module, open for extension (add an implementation) / closed for modification (don't touch callers), segregated interfaces (don't force implementations to stub methods they can't support — model that with the abstraction).

Subject: [PATCH 136/223] feat(home): collapsed Models control + per-type
 pickers; bump pro
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the two bulky model cards with a single compact Models control: a
labelled strip of four type icons (Text/Image/Voice/Speech), emerald when that
type has an active model. Tap → a manager bottom sheet with drill-in rows:
- Text/Image reuse the existing model picker
- Speech → Whisper picker (single active STT model, download+select)
- Voice → the pro voice picker (Kokoro voices)

Adds a reactive voiceSummary to the core ui-mode store (mirrored from pro) so the
Voice icon reflects voice state without core importing pro. Bumps pro
(single-Kokoro voice picker).

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the header's text-model name + image badge with a compact "Models ▾"
affordance that opens the same Models bottom sheet used on home. Text/Image rows
open the existing chat model selector; Speech/Voice open the Whisper/Kokoro
pickers. Decouple ModelsManagerSheet from the home-only LoadingState type so it's
screen-agnostic (chat cross-imports the sheets for now; shared extraction is a
follow-up).

Subject: [PATCH 138/223] feat(settings): remove Voice Transcription + Text to
 Speech settings screens
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Voice and transcription are now managed entirely via the Models flow (Models tab
+ home/chat Models sheet), so both standalone settings screens are removed:
- delete the two Settings rows, the VoiceSettings/TTSSettings routes, and
  VoiceSettingsScreen (+ its test)
- clean the paths that opened them: chat generation-settings link, and the
  audio-mode toggle now routes to Models → Voice
- bump pro (drops the TTS settings screen registration)

Subject: [PATCH 139/223] =?UTF-8?q?feat(transcription):=20multi-model=20?=
 =?UTF-8?q?=E2=80=94=20select/download/delete=20per=20model?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Whisper now tracks every model present on disk (presentModelIds), not just the
single active one. The Transcription tab + the Speech picker show each on-disk
model as downloaded with the active one checked; tapping a downloaded-but-
inactive model selects it (no re-download), download is per-model, and delete is
per-model. Adds selectModel / deleteModelById / refreshPresentModels.

Subject: [PATCH 140/223] chore(home): delete dead ActiveModelsSection; drop
 audioSummaryLabel hook; bump pro

ActiveModelsSection was orphaned when the home cards became the Models strip.
Remove it (+ its test mock), the audioSummaryLabel HOOKS entry, and fix the
autoPlay-referencing tests.

Subject: [PATCH 141/223] test(audio): cover streaming TTS, multi-model
 transcription, voice routing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- waveform helpers (meanAbsAmplitude / buildWaveformEnvelope / waveformFromText)
- stream playback clock
- streamingSpeech coordinator: gating (voice mode + engine ready), thinking is
  never spoken, queue drains through the engine, trailing-partial flush, reset
- whisperStore multi-model: refreshPresentModels / selectModel (no re-download)
  / deleteModelById (active + non-active)
- ttsStore: play→synthesize routing, seek no-op for streaming, setEngine
  fallback to default, live engine speed on updateSettings

Subject: [PATCH 142/223] refactor(models): move shared model sheets to
 components + shadow the home Models card

Relocate ModelsSummaryRow/ModelsManagerSheet/VoiceModelsSheet/WhisperPickerSheet
from src/screens/HomeScreen/components to src/components/models so the home and
chat screens consume one shared implementation instead of two parallel copies.
Give the collapsed home Models card the surface+shadows.small treatment to match
the other home cards. Add RNTL coverage for ModelsSummaryRow and
ModelsManagerSheet, and rewrite the VoiceModelsPanel test for the voice-picker
behaviour.

Subject: [PATCH 146/223] chore(knip): add tuned config and remove dead code it
 surfaced

Add knip.json scoped to the core app (src/**, with App.tsx + tests + the pro
loader as entries; pro/ is a separate repo with its own usage and stays out of
the project graph). Remove the dead code knip found and grep confirmed unused
across both src and pro:

- delete unused LoadingOverlay screen component
- drop the legacy ChatToolbar alias (only QueueRow is consumed)
- remove the dead LoadingScreen chat component and its orphaned import
- remove unused exports: items extractQuantization (huggingface has its own),
  getHook, showLoadingAlert, processSSELines, parseSSEFromText (+ barrel
  re-export), PILL_ICONS_WIDTH, SYSTEM_PROMPT_RESERVE, CONTEXT_SAFETY_MARGIN,
  PRO_URL
- drop redundant default exports duplicating named ones (DebugLogsScreen,
  RemoteServerModal, RemoteServersScreen)

Kept intentional surfaces knip flags but that are real: the _clear*ForTesting
seams, the provider ModelLoadState/ProviderFactory types, ThemeMode, and
stripMarkdownForSpeech (consumed by pro, invisible to a src-scoped graph).

Subject: [PATCH 148/223] test: update screen tests for the model-selector +
 voice redesign

The earlier home/chat/settings redesign left several RNTL suites asserting UI
that no longer exists. Update the tests (no app code) to assert the current
behaviour:

- HomeScreen / HomeScreenSpotlight: assert the collapsed ModelsSummaryRow
  (Models label + Text/Image/Voice/Speech captions) and that per-model details,
  load/unload, eject, and "browse more" now live inside the manager + picker
  sheets opened from it; drop the deleted LoadingOverlay mock.
- ChatScreen: header now shows a generic "Models" selector that opens the
  manager sheet (then the per-type picker), not the model name inline; reset
  lastTextModelId between tests for isolation.
- SettingsScreen: the Voice Transcription and Text to Speech rows were removed;
  assert their absence and cover the remaining rows.
- ChatInputModeToggle: not-ready tap navigates to ModelsTab { initialTab:
  'voice' }.
- TranscriptionModelsTab: cover the multi-model store API (presentModelIds,
  selectModel without re-download, per-model deleteModelById).

Full suite: 5629 passing, tsc + eslint clean.

Subject: [PATCH 149/223] chore(pro): bump submodule to merged audio-mode tip
 (c00afad8)

Advance the pro pointer to the conflict-resolved merge of
feat/email-calendar-tools into fix/kokoro-install-status, so this branch
references a pro commit that exists on origin and the pro PR merges cleanly.

Subject: [PATCH 151/223] feat(mcp): native OAuth adapters, boot wiring, and
 redirect scheme

- mcpOAuthNativeAdapters: secure browser (InAppBrowser.openAuth), Keychain
  token storage, and PKCE crypto (get-random-values + js-sha256), implementing
  the adapter seams pro exposes.
- loadProFeatures: inject the adapters via pro.configureOAuthAdapters after the
  entitlement check; loaded lazily so free builds never pull the native libs.
- Register the offgrid://oauth redirect scheme in Info.plist and AndroidManifest.
- Bump pro submodule to the MCP OAuth commits.

Subject: [PATCH 153/223] chore: remove orphaned website revenuecat-link test

website/ was moved to its own repo in #407, but this test was left behind
referencing the deleted website/assets/js/revenuecat-link.js, so the suite
fails to load. Remove the dead test (the code it covered now lives elsewhere).

Subject: [PATCH 154/223] feat(settings): release-visible Debug Logs button +
 MCP OAuth browser log

- SettingsScreen: move the Debug Logs entry out of the __DEV__ block so issues
  can be captured and shared from release builds (capture path was never
  __DEV__-gated; only this button was).
- mcpOAuthNativeAdapters: log browser availability and openAuth result type.

Subject: [PATCH 155/223] fix(tools): inject MCP hint once, and only when no
 native tool calling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Local tool calls (both MCP and built-in) were failing because the model got two
conflicting instructions: the <mcp_tool_call> text hint AND the engine's native
tool template. The model then emitted a hybrid format (e.g. <notion-search …/>)
that neither llama.cpp nor our parsers recognise, so calls fell through as text.

- useChatGenerationActions: stop appending the extension hint here (it was also
  added in the tool loop — double injection). Single source now.
- augmentSystemPromptForTools: only add the MCP text hint when the model lacks
  native tool calling; LiteRT/remote/llama-with-tool-template rely on the
  structured tools instead.
- Add a [ToolLoop] diagnostic log (tool count + total schema char size).
- Bump pro submodule (schema trim, OAuth logs, tool-count fix).

Subject: [PATCH 157/223] fix(ci): move pro-source tests into the pro submodule
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The main CI doesn't check out the private pro/ submodule (and tsconfig excludes
pro/**), so __tests__/unit/pro/*.test.ts — which import pro source directly —
failed lint/typecheck/test in CI. The tests now live in pro/__tests__ (pushed in
the pro repo). Bumps the pro submodule pointer to include them.

Subject: [PATCH 158/223] fix(settings): keep Debug Logs dev-only; bump pro
 pointer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Revert the release-visible Debug Logs button — it stays behind __DEV__ and is
  stripped from release builds. Also brings SettingsScreen back under the 500-line
  lint limit (the release-visible block had pushed it to 503).
- Bump pro submodule to 16e97aa (relocated pro-source tests).

Subject: [PATCH 159/223] test: fix tool-loop mock + cover tool-call parsing
 and native OAuth adapters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Restores the CI test + coverage jobs that the fix-C change had broken:

- generationToolLoop.test.ts: stub llmService.supportsToolCalling in the mock
  (fix C now calls it in callLLMWithRetry — the missing stub failed all 42
  tests in the suite). Add tests for the text tool-call parsing fallbacks
  (Gemma <|tool_call> JSON/unquoted/unclosed/colon args, <tool_call>
  function-call/bare/standard-JSON styles) and the empty-query backfill — the
  robustness layer that was previously uncovered.
- mcpOAuthNativeAdapters.test.ts: new — covers the browser/storage/crypto
  adapters (browser availability, success/cancel, keychain get/set/remove,
  random bytes, sha256). Brings the new file to 100% and global branch
  coverage back over the 80% threshold.

Subject: [PATCH 160/223] fix(android-test): relax bytecode verification for
 unit tests (Amazon IAP VerifyError)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Amazon IAP's com.amazon.device.iap.ResponseReceiver (pulled in transitively via
RevenueCat) ships pre-Java-7 bytecode without stackmap frames. Robolectric
instantiates every manifest-declared receiver during application setup, so that
class fails strict bytecode verification on JDK 17+
(VerifyError: "Expecting a stackmap frame at branch target"), which failed all 11
DownloadCompleteBroadcastReceiverTest cases. Add -noverify to the unit-test JVM so
the third-party class loads.

This surfaced only now because the Android test CI step was skipped in prior runs
(the Jest step failed first); it is unrelated to the JS changes in this PR.
Verified locally on JDK 17 (CI parity): full testDebugUnitTest suite — 4 classes,
82 tests — passes with 0 failures.

Subject: [PATCH 161/223] fix(pro): open unlock modal in verify mode from
 "Already paid?"

Both the "Get Pro" CTA and "Already paid? Unlock with email" called the same
openEmailModal() with no mode, and the modal always initialised to 'pay'. So
tapping "Already paid?" landed on "Continue to payment / $50" and the user had to
tap the in-modal "Already paid? Verify email instead" toggle again to reach email
verification.

ProUnlockModal now takes an initialMode and re-applies it whenever it opens (the
modal stays mounted, so a useEffect on `visible` is needed). ProDetailScreen opens
'pay' from Get Pro and 'verify' from "Already paid?". Adds tests for both paths.

Subject: [PATCH 162/223] feat(home): animated load progress + rotating tips on
 the loading overlay

Replace the bare spinner with an eased progress bar (creeps toward a 90% ceiling
over the expected load window, never claims "done" before the model loads) and a
rotating set of loading tips so the wait reads as "working" and teaches useful
behaviour. Tip copy follows the brand voice guide.

Subject: [PATCH 163/223] fix(logging): re-wire in-app debug viewer dev-only
 after taking main's logger
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The merge took main's no-op-in-release logger (the ANR/perf fix), which dropped
setLogListener — leaving the dev Debug Logs viewer fed by nothing. Re-tap
logger.log/warn/error into the debug store inside a __DEV__ block so the dev
viewer works again. Release builds strip the block entirely, so logging stays a
no-op there (no file I/O, no listener) exactly as on main.

Subject: [PATCH 164/223] test: restore branch coverage above 80% after merging
 main

Merging main's newer code nudged global branch coverage to 79.93%. Cover the gaps:
- debugLogsStore: ring-buffer cap + clear (was 0%).
- proLicenseService: resetProIdentityForTesting (anonymous/non-anonymous/error)
  and activateProByEmail error paths (logIn failure, miss + logOut failure).

Branch coverage back to 80.06%.

Subject: [PATCH 165/223] feat(pro): reframe unlock copy around 'membership' /
 Get Pro

Updates the Pro unlock modal and detail-screen copy to a membership
framing: 'Get Pro' / 'Verify membership' CTAs, 'Already a member?' /
'Not a member yet?' toggles, and membership-worded subtitles and errors.
Adds a testID to the modal CTA so tests target it unambiguously now that
the pay button label ('Get Pro') matches the screen buttons.

Subject: [PATCH 166/223] feat(litert): two-pass tool selection for large tool
 sets

Small on-device models can't fit many tool schemas in context, so MCP-heavy
setups (e.g. Notion's ~17 tools) produce empty/garbled calls or no response. For
LiteRT only, add a fast tools-free routing pass: list the enabled tools' names +
one-line descriptions, ask the model which are relevant, then carry only the
selected schemas into the real generation pass.

- litert.generateToolSelection: one-shot routing on a throwaway native session
  (temp 0, no tools, no history) so it never enters chat or the real
  conversation's context; drops the session afterward.
- litertToolSelector.selectLiteRTTools: builds the catalog, lenient name match.
- runToolLoop: gated on isLiteRTActive() + >5 tools; filters toolSchemas to the
  selected set; falls back to all tools on any miss or failure.

Complements the existing per-tool schema trim (fewer tools + smaller each).
llama/remote paths untouched. Selector branches covered by tests.

Subject: [PATCH 167/223] fix(litert): recover from native tool-call parse
 failures instead of crashing

When the litertlm native FC parser hard-fails (Status Code 3) on a malformed tool
call, callLiteRTForLoop now catches it and retries once WITHOUT tools, so the user
gets a text answer instead of a raw "Generation Error". Pairs with the required-only
schema trim (bumped pro), which removes most of what the model mangles.

Subject: [PATCH 168/223] chore(deps): add react-compiler-runtime

The pro submodule's components are compiled with babel-plugin-react-compiler,
which needs react-compiler-runtime at runtime. Without it the app crashed on
boot (Cannot read property 'useMemoCache' of null).

Subject: [PATCH 169/223] fix(chat): restore KeyboardAvoidingView keyboard
 avoidance
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The custom androidKbPad manual-padding mechanism floated the input mid-screen
above the keyboard in both chat and voice. Revert to main's approach — a plain
KeyboardAvoidingView behavior="padding" on both platforms — and drop the
androidKbPad state/listeners.

Subject: [PATCH 170/223] fix(models): engine-aware loaded check so LiteRT
 models don't reload
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

loadTextModel's fast-path checked only llmService.isModelLoaded(), which is
always false for a LiteRT model (it loads in liteRTService). So an already-loaded
LiteRT model fell through and reloaded (unload+load) on chat open — the "second
loader". Check the right service per the model's engine.

 thinking bar icon, pass onSend to audio

- Render the pro mode-toggle slot in the header subtitle row (next to Models)
  instead of the collapsing input icon row, so it's always visible.
- Remove the thinking (zap) icon from the input pill; thinking stays in the
  quick-settings popover.
- Pass onSend to the audio-mode slot so Voice mode's Type-instead can send.

Subject: [PATCH 176/223] feat(pro): Get Pro opens web pay page directly; modal
 is verify-only
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- 'Get Pro' (header + CTA) now opens the web pay page
  (https://offgridmobileai.co/pay) directly via Linking — no in-app email,
  no modal, and the $50 pill is gone.
- ProUnlockModal is now verify-only: enter the email tied to an existing
  Pro membership and re-check the entitlement. A footer link ('Not a member
  yet? Get Pro') opens the same pay page.
- Add PRO_PAY_PAGE_URL to proLicenseService (public, non-secret URL).
- Tests rewritten for the new flow.

Subject: [PATCH 177/223] feat(litert): surface curated LiteRT models in
 onboarding

Add the curated LiteRT models to the onboarding download screen (Android
only, filtered to what fits in RAM), with a LiteRTModelCard and download
handlers that route through the same pipeline as the GGUF cards.

Refactor the curated-LiteRT plumbing into curatedLiteRTRegistry as the
single source of truth: move LITERT_PARENT_ID there and add
buildCuratedLiteRTFiles(), so both the ModelsScreen browser and onboarding
build their cards from one place instead of duplicating the mapping.

Subject: [PATCH 179/223] chore: bump pro submodule to include 'drop MCP
 Servers settings entry'

Merges the base's now-pushed pro tip (e23a00b5, feat/mcp-oauth) into our audio
pro line. Resolved index.ts: dropped the MCP Servers settings registration (per
the base) while keeping the audio activation.

Subject: [PATCH 180/223] fix(ios): consolidate react-native-fs onto the
 @dr.pogodin fork

Two react-native-fs packages produced duplicate RNFS Objective-C symbols at
link time on iOS: the app's react-native-fs plus executorch's bare-resource
fetcher, which pulls the maintained @dr.pogodin fork. Drop the old package and
alias 'react-native-fs' onto the fork so a single native module ships.

- remove react-native-fs from package.json and Podfile.lock
- src/shims/react-native-fs.ts: re-export the fork and provide the default
  import the callers expect (the fork has named exports only)
- alias the old specifier in metro / jest / tsconfig
- AppDelegate + bridging header: background-download completion moved from
  RNFSManager to RNFSBackgroundDownloads (also fixes iOS Kokoro downloads)
- migrate RNFS.ReadDirItem -> ReadDirResItemT in modelManager and tests

Note: loaders.ts also carries a supportsAudio change committed with the
Android LiteRT audio work; only its RNFS type rename is in this commit.

Subject: [PATCH 181/223] feat(litert): direct audio input for LiteRT models on
 Android

Gemma 4 E2B/E4B can take audio directly (no Whisper STT). Thread an audio
capability + audio attachments end to end so a recorded clip is sent to the
model as Content.AudioBytes.

- native LiteRTModule: loadModel(audioEnabled), sendMessageWithAudio, and
  buildSendContents emits Content.AudioBytes from the full .wav file (litert-lm
  decodes it with miniaudio, which needs a container, not raw PCM)
- litert.ts: supportsAudio(), loadModel audio flag, sendMessage/generateRaw take
  a { imageUris, audioUris } media object
- activeModelService.supportsAudioInput(): engine-aware dispatch so UI/hooks
  never branch on engine type
- generationServiceHelpers + tool-loop path: route audio attachments; an
  audio-only turn (empty text) no longer short-circuits
- liteRTAudio capability plumbed through curated registry, storage, and types
- ChatInput voice: gate direct audio through activeModelService

Subject: [PATCH 182/223] feat(tools): two-pass tool routing for on-device
 models (iOS llama + LiteRT)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When many tools are enabled, a small on-device model can't fit every schema in
context. A fast tools-free routing pass picks the relevant tools first, then
only those drive the real generation pass.

- litertToolSelector: rename selectLiteRTTools -> selectRelevantTools, make it
  engine-agnostic via an injected generate fn, and return three states
  (names | [] no-tool-needed | null unusable -> caller keeps all)
- llm.ts: generateToolSelection — ephemeral, tools-free routing completion
- generationToolLoop.selectEffectiveSchemas: always keep built-in tools; route
  only the MCP/ext tools. LiteRT routes on a throwaway native session; llama
  routes only on iOS (Metal makes the extra prefill cheap; on Android it
  spiked TTFT). Remote keeps the full set.

Note: generationToolLoop.ts also carries the LiteRT audio routing committed in
the previous commit; this commit holds only its tool-routing changes.

+# Plan: Phase-aware progress captions for audio mode (no "is it broken?" gaps)
+
+## Goal
+When a user sends a voice message, several silent gaps occur (prefill, thinking,
+TTS synthesis). Today all of them show the same pulsing dots, so the user can't
+tell working-but-slow from stuck. Add a short status caption that names the phase,
+designed so it can never flicker, reverse, or get stranded.
+
+## Non-goal
+Do NOT build a new independent state machine or timers. The caption must be a pure
+function of state that already exists, gated by the same condition that mounts the
+in-progress bubble, so it cannot outlive or contradict that bubble.
+
+---
+
+## The gaps (current behavior)
+
+| Phase | Trigger | Shown now |
+|---|---|---|
+| A. Prefill | sent → before first token (~3-5s, audio TTFT) | pulsing dots, silent |
+| B. Thinking | reasoning tokens stream (thinking enabled); never spoken | same dots, silent |
+| C. Synthesis | answer streaming; Kokoro synthesizing first sentence | play button + tiny spinner, silent |
+| D. Playing | audio plays | waveform animates (good) |
+
+Streaming TTS (`pro/audio/index.ts` `audio.onStreamingToken` → `feedStreamingText`)
+speaks sentence-by-sentence, so C and the tail of answer-generation OVERLAP. The
+design must tolerate overlap rather than force a linear phase.
+
+---
+
+## Design: monotonic phase, pure-derived, playback wins
+
+### Signal sources (read-only; do not add new state)
+- Message: `msg.isThinking`, `msg.reasoningContent`, `msg.content`.
+- TTS store (`pro/audio/ttsStore.ts`): `playbackStatus`, `currentMessageId`, derived `isSpeaking`/`isLoading`.
+- The bubble already mounts on `isStreamingThis || isThinkingItem`
+  (`pro/audio/ui/MessageAudioMode.tsx` `renderAudioInProgress`).
+
+### Phase ladder (advance-only)
+```
+0 waiting   → "Processing your message…"   (in-progress, no reasoning, no answer yet)
+1 thinking  → "Thinking…"                   (reasoningContent growing AND content empty)
+2 answering → "Preparing audio…"            (content non-empty, TTS not yet playing THIS msg)
+3 playing   → (no caption; waveform owns UI)(currentMessageId===msg.id && playing)
+```
+Rules that kill the failure modes:
+1. **Monotonic.** Keep a ref of the highest phase reached for this messageId; never
+   render a lower phase even if a signal momentarily regresses. (Prevents flicker /
+   backward "Preparing→Thinking".)
+2. **Playback wins.** If `ttsStore.currentMessageId === msg.id` and status is
+   playing/processing → phase 3, caption empty, waveform shows progress. Never draw a
+   caption over real audio.
+3. **Cross-message gate.** Only read `playbackStatus` when
+   `currentMessageId === msg.id`; otherwise treat as not-playing. (Prevents a prior
+   message's TTS state bleeding onto this bubble.)
+4. **Lifetime = bubble.** Caption is rendered only inside the in-progress bubble
+   (gated on `isStreamingThis || isThinkingItem`). On error/abort/finalize the bubble
+   unmounts → caption gone. It can never strand on "Thinking…".
+5. **Graceful "thinking" detection.** Only show "Thinking…" when reasoning is actively
+   growing AND answer still empty. If the model's reasoning format is unparseable
+   (see `buildAudioBubbleProps` note), fall back to "Responding…" rather than assert a
+   phase. Never block the answer on a wrong thinking guess.
+
+### Why this avoids the documented risks
+- Flicker/reverse → blocked by monotonic ref (rule 1).
+- Overlap of generate+speak → playback-wins (rule 2) yields to the waveform.
+- Singleton bleed → message-id gate (rule 3).
+- Stuck terminal state → lifetime tied to bubble (rule 4); no independent state to leak.
+- Parser fragility → graceful fallback (rule 5).
+
+---
+
+## Implementation
+
+### 1. New hook: `useAudioProgressPhase(msg)` — `pro/audio/ui/AudioMessageBubble/useAudioProgressPhase.ts`
+- Subscribe narrowly to `ttsStore`: `currentMessageId`, `playbackStatus` (select only
+  these two to limit re-renders).
+- Compute raw phase from the ladder above using `msg` + gated TTS read.
+- Hold `useRef(maxPhase)` keyed by `msg.id`; clamp raw phase up to it (reset the ref
+  when `msg.id` changes).
+- Return `{ phase, caption }` where caption is '' for phase 3.
+- Copy (brand voice — plain, no exclamation, no em dash):
+  - 0 → `Processing your message…`
+  - 1 → `Thinking…`
+  - 2 → `Preparing audio…`
+  - fallback → `Responding…`
+
+### 2. `AudioMessageBubble/index.tsx`
+- Accept optional `statusCaption?: string` (or call the hook directly when `isLoading`).
+- In the `isLoading && !isUser` branch, render the caption as a META-styled `Text`
+  beside/under `ThinkingDots`. Keep dots animating (moving indicator + label).
+- Use `TYPOGRAPHY.meta` + `colors.textMuted`. No new colors, no hardcoded sizes.
+
+### 3. `MessageAudioMode.tsx`
+- In `renderAudioInProgress`, pass the computed caption into `AudioMessageBubble`
+  (or let the bubble call the hook; either is fine since it's pure).
+
+### 4. Instant bubble on send (close Gap A's "nothing on screen")
+- Verify the assistant in-progress placeholder (`msg.isThinking` item or streaming
+  message) is added to the store IMMEDIATELY on send, before prefill completes. If
+  there's a delay, the user sees only their own bubble + silence during prefill.
+- Trace: core generation path that creates the thinking/streaming placeholder
+  (`src/services/generationService*`, `useChatGenerationActions`). If the placeholder
+  is created only on first token, add it at generation start for audio mode. Confirm
+  on-device that the dots+caption appear within ~100ms of sending.
+
+---
+
+## Tests (both unit + integration, per project rules)
+
+Unit (`__tests__/unit/...`):
+- `useAudioProgressPhase`: returns correct caption per signal combo.
+- Monotonic clamp: feed phase 2 then a regressing signal → still phase 2.
+- Cross-message gate: `currentMessageId` = other id → playback ignored.
+- Playback wins: this-id + playing → phase 3, empty caption.
+- Unparseable thinking → "Responding…", never blocks.
+- Reset on `msg.id` change → maxPhase ref resets.
+
+Integration (`__tests__/integration/...`):
+- Simulated send → prefill → thinking → answer → TTS preparing → playing: caption
+  advances 0→1→2→'' and never regresses.
+- Error mid-thinking: in-progress bubble unmounts, no stranded caption.
+
+---
+
+## Risk register (carry into review)
+- Re-render cost: select only 2 TTS fields; memoize caption. Verify no per-token
+  re-render storm of all bubbles.
+- Streaming vs fallback TTS: "Preparing audio…" may flash briefly (streaming) or
+  linger (fallback) — acceptable; both read as "working".
+- Copy review: run the brand-voice checklist on the four strings before commit.

Subject: [PATCH 184/223] fix(audio): bump pro for TTS low-RAM +
 react-native-fs shim

Pulls in the pro-side fixes: voice models are no longer hard-blocked on
low-RAM devices, and react-native-fs resolves to the @dr.pogodin shim to match
the app-side consolidation (iOS Kokoro install/download path).

Subject: [PATCH 185/223] fix(ui): open the next sheet only after the Models
 manager fully closes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

iOS can't present one modal while another is dismissing — opening a picker or
the eject confirmation while the Models manager was still closing wedged every
sheet (none would open until an app reload).

- AppSheet: new onClosed prop, fired only after the close animation finishes
  and the modal is hidden
- ModelsManagerSheet: forwards onClosed
- HomeScreen: stash the action (closeManagerThen) and run it from onClosed, so
  the next sheet opens after the manager is gone; Eject All routes through the
  same path so its confirmation no longer collides

Note: AppSheet.tsx and HomeScreen.tsx still carry temporary [SheetDbg]
console.log lines — strip before this is pushed.

Subject: [PATCH 186/223] test(chat-input): give useAppStore mock a getState
 for supportsAudioInput
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ChatInput renders → Voice.ts supportsDirectAudio() →
activeModelService.supportsAudioInput(), which reads useAppStore.getState().
The test's store mock only stubbed the hook, not getState, so all ChatInput
render tests threw "useAppStore.getState is not a function". Add getState
(mirroring the existing useUiModeStore mock) and seed downloadedModels /
activeModelId so supportsAudioInput resolves to false. Test-only.

- index.js: load react-native-url-polyfill at boot. RN's built-in URL mangles
  discovery paths (adds a trailing slash → 404), which broke the SDK's OAuth
  discovery; the polyfill makes new URL() spec-compliant before any OAuth runs.
- deps: add @modelcontextprotocol/sdk and react-native-url-polyfill.
- bump pro submodule to the MCP SDK OAuth discovery + manual client_id commit.

Subject: [PATCH 188/223] test: update ChatInputModeToggle test to the dropdown
 UX + bump pro submodule
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The component was reworked into a chip-opens-dropdown (testID chat-mode-toggle →
mode-option-*), gated on the model being downloaded. Rewrite the test to that flow
(shim measureInWindow so the menu opens). Also bump the pro submodule pointer to
include the MCP discovery test cleanup.

Subject: [PATCH 189/223] fix(litert): send image and audio together in one
 turn
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

sendMessage routed audio XOR image (if audio present, the audio-only native
method dropped the images), so an audio-mode turn with an attached image lost
the image and the model replied "no image attached". Add a native
sendMessageWithMedia(text, imageUris, audioUris) — buildSendContents already
composes image + audio + text — and route both modalities through it when both
are present. Image-only and audio-only paths are unchanged.

Subject: [PATCH 190/223] fix(audio): clear attachments after a keyboard send
 in audio mode

The mic path (onAutoSend) cleared attachments after sending, but the audio-mode
keyboard ("type instead") path called onSend directly without clearing, so an
attached image/PDF lingered and was re-sent on the next message. Pass
clearAttachments into the audio slot (paired with the AudioModeLayout change).

Subject: [PATCH 193/223] fix(whisper): keep transcription model list in sync
 with disk

Add a per-model downloadingId so only the row being downloaded spins
(the old global isDownloading lit up every not-yet-present row). Clear
it in a finally so a hung/failed auto-load never leaves it stuck.

refreshPresentModels now reconciles the active pointer against disk: a
delete from the Download Manager bypasses this store, so downloadedModelId
could point at a model whose file is gone. Re-derive the list on screen
focus so returning from the Download Manager stays in sync.

Subject: [PATCH 197/223] feat(components): add centered alert dialog

A centered fade-Modal alert (vs CustomAlert's bottom sheet). Less prone to
the iOS present-while-dismiss conflict, so it suits confirms triggered from
inside another modal/menu. Shares the AlertButton/showAlert API.

 LoadingOverlay

The manager-sheet pickers and eject alert now run via onClosed
(closeManagerThen), so the AppSheet mock must fire onClosed when it goes
invisible. Also assert the full-screen LoadingOverlay shows during load,
which is the shipped behaviour (the prior 'no overlay' assertion was stale).

Subject: [PATCH 205/223] fix(audio): wire MCP sheet into the audio-mode quick
 settings

The audio-mode quick-settings popover's MCP entry did nothing because ChatInput
never forwarded onMcpPress/mcpToolCount to the audio slot (the chat-mode path
already passes them). Pass both through so the MCP servers sheet opens from
audio mode too.

Subject: [PATCH 206/223] test(audio): update ChatInputModeToggle for
 alert-based no-model flow

Choosing Voice with no model now shows a prompt (then routes to the nested
Main > ModelsTab > Voice on 'Get voice model'), instead of navigating
directly. Drive that flow on the Android path (iOS defers the alert to the
dropdown's onDismiss, which jest can't fire).

Subject: [PATCH 209/223] chore(logs): strip verbose debug logging from
 services and LiteRT

Remove branch-added logger.log/info/debug (JS) and Log.i (Kotlin) noise
from the litert / tool-loop / model lifecycle / pro-license / whisper /
classifier paths. Keeps all warn/error logging, logs that already
existed on main, and control-flow logs (model-residency unload catches,
LiteRT first-message marker). Drops now-unused logger imports and locals
that only fed those logs. No behaviour change.

Subject: [PATCH 213/223] fix(deps): pin react-native-zip-archive to 7.1.0 so
 patch-package applies

package.json used ^7.1.0, which let the lockfile drift to 7.1.1. The
NPE-crash patch (patches/react-native-zip-archive+7.1.0.patch) only
applies to 7.1.0, so patch-package failed during npm ci, breaking the
install step and thus every CI job (lint/test/typecheck/android-build).
Pin to exact 7.1.0 to keep the patch applicable. 7.1.1 offered nothing
needed (its only relevant change, the (int) compressionLevel cast, is
already in the patch).

Subject: [PATCH 214/223] test(ci): exclude pro-submodule suites from the
 public repo's CI

The audio/TTS test suites import directly from the private pro/ submodule
(pro/audio/*) via relative paths. The public repo's CI checkout does not
(and must not) include that private submodule, so those modules can't
resolve there, failing both typecheck and the jest run.

Exclude the 10 pro-dependent suites from jest (testPathIgnorePatterns) and
tsconfig (exclude). They continue to run in the pro repo's own CI, where
both core and pro are present. No source or behavior change.

Subject: [PATCH 215/223] fix(deps): pin react-native-zip-archive to 7.1.0 so
 patch-package applies

Same drift fix as on feat/pro-feature-registry: ^7.1.0 let the lock
move to 7.1.1, which the +7.1.0 patch can't apply to, failing npm ci.
Pin exact 7.1.0. Needed here so the pro repo's CI (which pairs against
this branch) can install cleanly.

Subject: [PATCH 216/223] fix(ios): activate the AVAudioSession before
 recording
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On iOS the recorder needs an active AVAudioSession in a record-capable
category. Nothing configured it, so the native start() returned "Audio session
is not active", no WAV was written, and stop() failed with "Recording failed to
save" — so voice/audio mode produced no input. Configure playAndRecord (so TTS
playback can share the session) + defaultToSpeaker and activate it before
recording (iOS only; Android is unchanged). Also surface a failed native
start() instead of silently continuing to a doomed stop().

 react-native-background-downloader
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The @kesha-antonov/react-native-background-downloader dep (com.eko) was
added in 908af16a for the original in-core TTS work, which has since
moved to the pro submodule and uses a different downloader. Nothing in
core or pro imports it, and no patch depends on it — it only autolinks a
ResumableDownloadService (notification foreground service) that trips the
NotificationPermission Android lint error (POST_NOTIFICATIONS was removed
in 13e63696). Removing it kills that lint error at the source.

 audio-api playback notification)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

react-native-audio-api declares a PlaybackNotification capability in its
manifest, which lint flags as needing POST_NOTIFICATIONS. The app only
uses AudioContext for playback (and AudioManager for the recording audio
session) — it never uses the now-playing/media-session API, so it never
posts that notification. POST_NOTIFICATIONS was intentionally dropped in
13e63696. Baseline the finding (a known, unused library capability)
rather than re-add a permission for a notification we never show.

Subject: [PATCH 220/223] chore(pro): remove temporary 'Reset Pro identity'
 testing button
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ungated-in-release dev button (flagged TEMPORARY) that called
resetProIdentityForTesting to clear the RevenueCat identity. Removed the
button, its now-unused Alert / resetProIdentityForTesting imports, and
the test that exercised it. Kept the restoreButton/restoreText styles —
shared with the real 'Already a member? Verify with email' button.

Subject: [PATCH 221/223] test: raise Jest branch coverage to 82.69% to pass CI
 gate

Add targeted unit/RNTL tests covering previously-uncovered branches
(error paths, ??/|| fallbacks, try/catch, guard clauses, early returns)
across services, stores, hooks, and components. No source or config
changes; coverage thresholds and collectCoverageFrom are untouched.

Global branch coverage 78.2% -> 82.69% (statements/functions/lines all
remain >= 80%). Files covered: litert, generationToolLoop,
generationServiceHelpers, modelManager/scan, huggingface,
downloadHydration, activeModelService/loaders, whisperService,
tools/handlers, llmHelpers, hardware, audioRecorderService,
NumericStepper, downloadStore, useDownloadManager, useImageModels.

+/**
+ * Branch-coverage tests for litert.ts.
+ *
+ * These exercise the parts the main suite leaves uncovered:
+ *  - loadModel success + failure paths and option defaults
+ *  - resetConversation ??/|| fallbacks and JSON.stringify guards
+ *  - prepareConversation compaction path vs reset path vs no-op
+ *  - summarizeCurrentSession think-prefix stripping + handler install/restore
+ *  - warmup ready/not-ready/error paths
+ *  - sendMessage native event listeners (token/thinking/complete/error/tool_call)
+ *  - generateRaw resolve/reject + tool handler wiring
+ *  - generateToolSelection finally-invalidate
+ *  - getContextUsage / invalidateConversation / getMemoryInfo
+ *
+ * The native LiteRTModule const is captured at import time, so each test that
+ * needs a fresh module loads the service in an isolated module registry with
+ * its own mocked react-native + liteRTCompaction.

Subject: [PATCH 222/223] fix(downloads): keep Whisper download state in sync
 across surfaces
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Whisper (STT) state lived in two places: whisperStore (Home banner + Models
screen) and a direct disk read in the Download Manager. So deleting a Whisper
model in the Download Manager went straight through whisperService and never
updated whisperStore — leaving the Home banner and Models screen still showing
it as present/active. Downloads finishing elsewhere also didn't appear in the
Download Manager within the same session.

- Download Manager STT delete now routes through whisperStore.deleteModelById
  (unloads if active, deletes the file, updates presentModelIds/downloadedModelId),
  so all three surfaces update live.
- useVoiceDownloadItems subscribes to presentModelIds and refreshes when it
  changes, so a Whisper model downloaded from Home/Models appears in the Download
  Manager in the same session (on completion).

The deleted file is unchanged (same single ggml-<id>.bin by id); the only added
behaviour is the in-memory unload + store update. Live in-progress Whisper rows
in the Download Manager remain out of scope (the simpler approach).

+# Plan: Sync Whisper download state across Home banner, Models screen, Download Manager
+
+## Problem
+Whisper (STT) download state is inconsistent across the three places it appears.
+Downloading from one surface isn't reliably reflected in the others, and deleting
+in the Download Manager leaves the others showing the model as present.
+
+## Root cause — two sources of truth
+- **`whisperStore`** (persisted Zustand): `downloadedModelId` (active),
+  `presentModelIds` (on disk), `isDownloading` / `downloadingId` /
+  `downloadProgress`, plus `refreshPresentModels()` to reconcile with disk.
+  Used by **Home banner** (`HomeScreen` → `ModelsSummaryRow` "speech" row +
+  `WhisperPickerSheet`) and **Models screen** (`TranscriptionModelsTab`).
+- **`whisperService.listDownloadedModels()`** (disk scan, completed-only):
+  used by the **Download Manager** (`useVoiceDownloadItems`) directly.
+
+So Home ↔ Models are already in sync (same store). The **Download Manager** is the
+outlier:
+1. It only lists **completed** models from disk — an **in-progress** Whisper
+   download started from Home/Models never appears there.
+2. Its **delete bypasses `whisperStore`** (`deleteItem` → `whisperService.deleteModel`
+   with no `refreshPresentModels()` / `deleteModelById`), so Home + Models keep
+   showing the deleted model as present/active.
+3. `whisperStore.presentModelIds` is persisted and can drift from disk unless
+   `refreshPresentModels()` is called.
+
+(Home banner note: "speech" is already just one row in the unified
+`ModelsSummaryRow` alongside text/image — it shows the active model's name and
+opens `WhisperPickerSheet`. It is not a whisper-only screen.)
+
+---
+
+## Option A (recommended): make `whisperStore` the single source of truth
+
+Everything that shows or mutates Whisper download state goes through `whisperStore`;
+the Download Manager observes it instead of reading disk independently.
+
+1. **Download Manager reads `whisperStore`, not disk.**
+   - In `useVoiceDownloadItems`, source completed STT items from
+     `whisperStore.presentModelIds` (resolved to names via `WHISPER_MODELS`)
+     instead of `whisperService.listDownloadedModels()` — or keep the disk read
+     but only as the input to `refreshPresentModels()` (single reconcile path).
+   - Add an **in-progress** STT item when `whisperStore.isDownloading` (use
+     `downloadingId` + `downloadProgress`) so a Whisper download started anywhere
+     shows live in the Download Manager, matching how text/image in-progress items
+     work.
+2. **Delete goes through `whisperStore`.**
+   - `useVoiceDownloadItems.deleteItem` for `modelType === 'stt'` calls
+     `whisperStore.getState().deleteModelById(modelId)` (which already updates
+     `presentModelIds`/`downloadedModelId`) instead of `whisperService.deleteModel`.
+   - Result: deleting in the Download Manager immediately updates Home + Models.
+3. **Reconcile with disk on the right moments.**
+   - Call `whisperStore.refreshPresentModels()` on app boot and on Download Manager
+     focus so the persisted list can't drift from disk.
+
+Result: download or delete from **any** surface flows through one store; Home,
+Models, and Download Manager all reflect it, including in-progress.
+
+Files: `src/screens/DownloadManagerScreen/useVoiceDownloadItems.ts` (main),
+`src/stores/whisperStore.ts` (ensure `deleteModelById` + `refreshPresentModels`
+cover all cases), boot wiring (call `refreshPresentModels` once at startup).
+
+---
+
+## Option B (simpler fallback, per request): shrink the surface + fix delete sync
+
+If routing in-progress into the Download Manager is more than wanted now:
+
+1. **Home banner: stop being a Whisper download entry point.** Keep the "speech"
+   row as a **status/label only** (show active model / "—"); move actual Whisper
+   download+management to the Models screen + Download Manager. This removes one
+   surface that has to stay in sync.
+2. **Fix the one real desync** regardless: make the Download Manager's STT delete
+   go through `whisperStore.deleteModelById` and call `refreshPresentModels()`
+   after, so deletes converge across surfaces.
+3. Accept that **in-progress** Whisper downloads show only where they start
+   (Models screen), not live in the Download Manager — the Download Manager keeps
+   listing completed ones, just kept correct on delete + focus refresh.
+
+This is less code and still removes the confusing "downloaded here, still shows
+there" behavior, at the cost of not showing in-progress Whisper in the Download
+Manager.
+
+---
+
+## Recommendation
+Option A is the clean fix and not large — the Download Manager already has an
+in-progress concept for text/image; we're feeding Whisper's existing
+`whisperStore` progress into it and routing delete through the store. Do A unless
+we want the smallest possible change, in which case B step 2 (delete sync) is the
+must-fix.
+
+## Tests
+- Unit: `useVoiceDownloadItems` lists present models from `whisperStore`; shows an
+  in-progress item when `isDownloading`; delete calls `deleteModelById`.
+- Unit: `whisperStore.deleteModelById` clears `presentModelIds`/`downloadedModelId`.
+- Integration: download from Home → appears in Models + Download Manager; delete in
+  Download Manager → gone from Home + Models (no stale label).

Subject: [PATCH 223/223] fix(deps): restore react-native-background-downloader
 (used at boot)

Reverts the earlier removal. It is NOT unused: the voice-model disk scan
reads its directories.documents at boot (KokoroEngine refreshDiskStatus
-> listDownloadedModels -> listDownloadedFiles), so removing the dep left
the bundled JS calling an unlinked native module and crashed the app on
launch with 'react-native-background-downloader doesn't seem to be linked'.
Re-baseline its NotificationPermission lint (the dep's ResumableDownloadService).
