-
-**Configuration:**
-- Auto-scaling agent workers
-- Managed STT/TTS through inference endpoints
-- Built-in noise cancellation
-
-**Getting Tokens:**
-```typescript
-// From WellNuo backend
-const response = await fetch('/api/livekit/token', {
-  method: 'POST',
-  body: JSON.stringify({ roomName, userName })
-});
-const { token, url } = await response.json();
-```
-
-### 3. Julia AI Agent (Python)
-
-**Location:** `julia-agent/julia-ai/src/agent.py`
-
-**Stack:**
-- LiveKit Agents SDK
-- Deepgram Nova-2 (STT)
-- Deepgram Aura Asteria (TTS - female voice)
-- Silero VAD (Voice Activity Detection)
-- Custom WellNuo LLM (voice_ask API)
-
-## Setup & Deployment
-
-### Prerequisites
-
-1. **LiveKit Cloud Account**
-   - Sign up at https://cloud.livekit.io/
-   - Create a project
-   - Get API credentials
-
-2. **LiveKit CLI**
-   ```bash
-   # macOS
-   brew install livekit-cli
-
-   # Login
-   lk cloud auth
-   ```
-
-### Agent Deployment
-
-1. **Navigate to agent directory:**
-   ```bash
-   cd julia-agent/julia-ai
-   ```
-
-2. **Install dependencies:**
-   ```bash
-   uv sync
-   ```
-
-3. **Configure environment:**
-   ```bash
-   cp .env.example .env.local
-   # Add LIVEKIT_URL, LIVEKIT_API_KEY, LIVEKIT_API_SECRET
-   ```
-
-4. **Local development:**
-   ```bash
-   uv run python src/agent.py dev
-   ```
-
-5. **Deploy to LiveKit Cloud:**
-   ```bash
-   lk agent deploy
-   ```
-
-### React Native Setup
-
-1. **Install packages:**
-   ```bash
-   npm install @livekit/react-native @livekit/react-native-webrtc
-   ```
-
-2. **iOS permissions (Info.plist):**
-   ```xml
-   <key>NSMicrophoneUsageDescription</key>
-   <string>WellNuo needs microphone access for voice calls with Julia AI</string>
-   ```
-
-3. **Pod install:**
-   ```bash
-   cd ios && pod install
-   ```
-
-## Flow Diagram
-
-```
-User opens Voice tab
-        │
-        ▼
-Request microphone permission
-        │
-        ├─ Denied → Show error
-        │
-        ▼
-Get LiveKit token from WellNuo API
-        │
-        ▼
-Connect to LiveKit room
-        │
-        ▼
-Agent joins automatically (LiveKit Cloud)
-        │
-        ▼
-Agent sends greeting (TTS)
-        │
-        ▼
-User speaks → STT → WellNuo API → Response → TTS
-        │
-        ▼
-User ends call → Disconnect from room
-```
-
-## API Integration
-
-### WellNuo voice_ask API
-
-The agent uses WellNuo's `voice_ask` API to get contextual responses about the beneficiary.
-
-**Endpoint:** `https://eluxnetworks.net/function/well-api/api`
-
-**Authentication:**
-```python
-data = {
-    "function": "credentials",
-    "clientId": "001",
-    "user_name": WELLNUO_USER,
-    "ps": WELLNUO_PASSWORD,
-    "nonce": str(random.randint(0, 999999)),
-}
-```
-
-**Voice Ask:**
-```python
-data = {
-    "function": "voice_ask",
-    "clientId": "001",
-    "user_name": WELLNUO_USER,
-    "token": token,
-    "question": user_message,
-    "deployment_id": DEPLOYMENT_ID,
-}
-```
-
-## Troubleshooting
-
-### Common Issues
-
-1. **No audio playback on iOS**
-   - Check audio session configuration
-   - Ensure `expo-av` is properly configured
-   - Test on real device (simulator has audio limitations)
-
-2. **Microphone not working**
-   - Verify permissions in Info.plist
-   - Check if user granted permission
-   - Real device required for full audio testing
-
-3. **Agent not responding**
-   - Check agent logs: `lk agent logs`
-   - Verify LIVEKIT credentials
-   - Check WellNuo API connectivity
-
-4. **Connection fails**
-   - Verify token is valid
-   - Check network connectivity
-   - Ensure LiveKit URL is correct
-
-### Debugging
-
-```bash
-# View agent logs
-lk agent logs
-
-# View specific deployment logs
-lk agent logs --version v20260119031418
-
-# Check agent status
-lk agent list
-```
-
-## Environment Variables
-
-### Agent (.env.local)
-```
-LIVEKIT_URL=wss://live-kit-demo-70txlh6a.livekit.cloud
-LIVEKIT_API_KEY=your-api-key
-LIVEKIT_API_SECRET=your-api-secret
-WELLNUO_USER=anandk
-WELLNUO_PASSWORD=anandk_8
-DEPLOYMENT_ID=21
-```
-
-### React Native (via WellNuo backend)
-Token generation handled server-side for security.
-
-## Status
-
-**Current State:** WIP - Not tested on real device
-
-**Working:**
-- Agent deploys to LiveKit Cloud
-- Agent connects to rooms
-- STT/TTS pipeline configured
-- WellNuo API integration
-- React Native UI
-
-**Needs Testing:**
-- Real device microphone capture
-- Audio playback on physical iOS device
-- Full conversation loop end-to-end
-- Token refresh/expiration handling

-# FEATURE-002: LiveKit Voice Call with Julia AI
-
-## Summary
-
-Полноценный голосовой звонок с Julia AI через LiveKit Cloud. Пользователь нажимает кнопку "Start Voice Call", открывается экран звонка в стиле телефона, и он может разговаривать с Julia AI голосом.
-
-## Status: 🔴 Not Started (требуется полная переделка)
-
-## Priority: Critical
-
-## Problem Statement
-
-Текущая реализация имеет следующие проблемы:
-1. **STT (Speech-to-Text) работает нестабильно** — микрофон иногда детектируется, иногда нет
-2. **TTS работает** — голос Julia слышен
-3. **Код сложный и запутанный** — много legacy кода, полифиллов, хаков
-4. **Нет четкой архитектуры** — все в одном файле voice-call.tsx
-
-## Root Cause Analysis
-
-### Почему микрофон работает нестабильно:
-1. **iOS AudioSession** — неправильная конфигурация или race condition при настройке
-2. **registerGlobals()** — WebRTC polyfills могут не успевать инициализироваться
-3. **Permissions** — микрофон может быть не разрешен или занят другим процессом
-4. **Event handling** — события LiveKit могут теряться
-
-### Что работает:
-- LiveKit Cloud connection ✅
-- Token generation ✅
-- TTS (Deepgram Asteria) ✅
-- Backend agent (Julia AI) ✅

-
-## Technical Requirements
-
-### Dependencies (package.json)
-
-```json
-{
-  "@livekit/react-native": "^2.x",
-  "livekit-client": "^2.x",
-  "expo-keep-awake": "^14.x"
-}
-```
-
-### iOS Permissions (app.json)
-
-```json
-{
-  "ios": {
-    "infoPlist": {
-      "NSMicrophoneUsageDescription": "WellNuo needs microphone access for voice calls with Julia AI",
-      "UIBackgroundModes": ["audio", "voip"]
-    }
-  }
-}
-```
-
-### Token Server (already exists)
-
-- **URL**: `https://wellnuo.smartlaunchhub.com/julia/token`
-- **Method**: POST
-- **Body**: `{ "userId": "string" }`
-- **Response**: `{ "success": true, "data": { "token", "roomName", "wsUrl" } }`
-
----
-
-## Implementation Steps
-
-### Phase 1: Cleanup (DELETE old code)
-
-- [ ] 1.1. Delete `app/voice-call.tsx` (current broken implementation)
-- [ ] 1.2. Keep `app/(tabs)/voice.tsx` (entry point) but simplify
-- [ ] 1.3. Keep `services/livekitService.ts` (token fetching)
-- [ ] 1.4. Keep `contexts/VoiceTranscriptContext.tsx` (transcript storage)
-- [ ] 1.5. Delete `components/VoiceIndicator.tsx` (unused)
-- [ ] 1.6. Delete `polyfills/livekit-globals.ts` (not needed with proper setup)
-
-### Phase 2: New Architecture
-
-- [ ] 2.1. Create `hooks/useLiveKitRoom.ts` — encapsulate all LiveKit logic
-- [ ] 2.2. Create `app/voice-call.tsx` — simple UI component using the hook
-- [ ] 2.3. Create `utils/audioSession.ts` — iOS AudioSession helper
-
-### Phase 3: useLiveKitRoom Hook
-
-**File**: `hooks/useLiveKitRoom.ts`
-
-```typescript
-interface UseLiveKitRoomOptions {
-  userId: string;
-  onTranscript?: (role: 'user' | 'assistant', text: string) => void;
-}
-
-interface UseLiveKitRoomReturn {
-  // Connection state
-  state: 'idle' | 'connecting' | 'connected' | 'reconnecting' | 'disconnected' | 'error';
-  error: string | null;
-
-  // Call info
-  roomName: string | null;
-  callDuration: number; // seconds
-
-  // Audio state
-  isMuted: boolean;
-  isSpeaking: boolean; // agent is speaking
-
-  // Actions
-  connect: () => Promise<void>;
-  disconnect: () => Promise<void>;
-  toggleMute: () => void;
-}
-```
-
-**Implementation requirements**:
-1. MUST call `registerGlobals()` BEFORE importing `livekit-client`
-2. MUST configure iOS AudioSession BEFORE connecting to room
-3. MUST handle all RoomEvents properly
-4. MUST cleanup on unmount (disconnect, stop audio session)
-5. MUST handle background/foreground transitions
-
-### Phase 4: iOS AudioSession Configuration
-
-**Critical for microphone to work!**
-
-```typescript
-// utils/audioSession.ts
-import { AudioSession } from '@livekit/react-native';
-import { Platform } from 'react-native';
-
-export async function configureAudioForVoiceCall(): Promise<void> {
-  if (Platform.OS !== 'ios') return;
-
-  // Step 1: Set Apple audio configuration
-  await AudioSession.setAppleAudioConfiguration({
-    audioCategory: 'playAndRecord',
-    audioCategoryOptions: [
-      'allowBluetooth',
-      'allowBluetoothA2DP',
-      'defaultToSpeaker',
-      'mixWithOthers',
-    ],
-    audioMode: 'voiceChat',
-  });
-
-  // Step 2: Configure output
-  await AudioSession.configureAudio({
-    ios: {
-      defaultOutput: 'speaker',
-    },
-  });
-
-  // Step 3: Start session
-  await AudioSession.startAudioSession();
-}
-
-export async function stopAudioSession(): Promise<void> {
-  if (Platform.OS !== 'ios') return;
-  await AudioSession.stopAudioSession();
-}
-```
-
-### Phase 5: Voice Call Screen UI
-
-**File**: `app/voice-call.tsx`
-
-Simple, clean UI:
-- Avatar with Julia "J" letter
-- Call duration timer
-- Status text (Connecting... / Connected / Julia is speaking...)
-- Mute button
-- End call button
-- Debug logs toggle (for development)
-
-**NO complex logic in this file** — all LiveKit logic in the hook!
-
-### Phase 6: Testing Checklist
-
-- [ ] 6.1. Fresh app launch → Start call → Can hear Julia greeting
-- [ ] 6.2. Speak → Julia responds → Conversation works
-- [ ] 6.3. Mute → Unmute → Still works
-- [ ] 6.4. End call → Clean disconnect
-- [ ] 6.5. App to background → Audio continues
-- [ ] 6.6. App to foreground → Still connected
-- [ ] 6.7. Multiple calls in a row → No memory leaks
-- [ ] 6.8. No microphone permission → Shows error

-## Files to Create/Modify
-
-| File | Action | Description |
-|------|--------|-------------|
-| `hooks/useLiveKitRoom.ts` | CREATE | Main LiveKit hook with all logic |
-| `utils/audioSession.ts` | CREATE | iOS AudioSession helpers |
-| `app/voice-call.tsx` | REPLACE | Simple UI using the hook |
-| `app/(tabs)/voice.tsx` | SIMPLIFY | Just entry point, remove debug UI |
-| `services/livekitService.ts` | KEEP | Token fetching (already works) |
-| `contexts/VoiceTranscriptContext.tsx` | KEEP | Transcript storage |
-| `components/VoiceIndicator.tsx` | DELETE | Not needed |
-| `polyfills/livekit-globals.ts` | DELETE | Not needed |
-
----
-
-## Key Principles
-
-### 1. Separation of Concerns
-- **Hook** handles ALL LiveKit/WebRTC logic
-- **Screen** only renders UI based on hook state
-- **Utils** for platform-specific code (AudioSession)
-
-### 2. Proper Initialization Order
-```
-1. registerGlobals() — WebRTC polyfills
-2. configureAudioForVoiceCall() — iOS audio
-3. getToken() — fetch from server
-4. room.connect() — connect to LiveKit
-5. room.localParticipant.setMicrophoneEnabled(true) — enable mic
-```
-
-### 3. Proper Cleanup Order
-```
-1. room.disconnect() — leave room
-2. stopAudioSession() — release iOS audio
-3. Clear all refs and state
-```
-
-### 4. Error Handling
-- Every async operation wrapped in try/catch
-- User-friendly error messages
-- Automatic retry for network issues
-- Graceful degradation
-
----
-
-## Success Criteria
-
-1. ✅ User can start voice call and hear Julia greeting
-2. ✅ User can speak and Julia understands (STT works reliably)
-3. ✅ Julia responds with voice (TTS works)
-4. ✅ Conversation can continue back and forth
-5. ✅ Mute/unmute works
-6. ✅ End call cleanly disconnects
-7. ✅ No console errors or warnings
-8. ✅ Works on iOS device (not just simulator)

-## Notes
-
-### Why previous approach failed:
-
-1. **Too much code in one file** — voice-call.tsx had 900+ lines with all logic mixed
-2. **Polyfills applied wrong** — Event class polyfill was inside the component
-3. **AudioSession configured too late** — sometimes after connect() already started
-4. **No proper error boundaries** — errors silently failed
-5. **Race conditions** — multiple async operations without proper sequencing
-
-### What's different this time:
-
-1. **Hook-based architecture** — single source of truth for state
-2. **Proper initialization sequence** — documented and enforced
-3. **Clean separation** — UI knows nothing about WebRTC
-4. **Comprehensive logging** — every step logged for debugging
-5. **Test-driven** — write tests before implementation
