+# 🎉 Phase 2 - Final Updates & Enhancements
+
+**Date**: October 6, 2025, 11:20pm UTC+01:00  
+**Status**: Phase 2 Complete with Production Improvements ✅  
+**Version**: v0.2.1
+
+---
+
+## 📝 Session Overview
+
+This session focused on **production hardening** of Phase 2 features, fixing critical TTS issues, implementing audio caching, and adding chat persistence with intelligent audio management.
+
+---
+
+## ✅ Completed Enhancements
+
+### 1. TTS Playback Fixes ✅
+**Status**: Production Ready  
+**Priority**: Critical
+
+#### Problem
+- ElevenLabs audio blocked in Tauri despite having Tauri-specific implementation
+- Browser TTS fallback attempted to use ElevenLabs voice IDs
+- First audio play failed due to browser autoplay policy
+
+#### Solutions Implemented
+
+**A. Removed Tauri WebView Block**
+- **File**: `src/lib/tts.ts`
+- **Change**: Removed lines 72-76 that prevented ElevenLabs in Tauri
+- **Impact**: ElevenLabs audio now works in Tauri using base64 data URLs
+- **Benefit**: Full ElevenLabs functionality in desktop app
+
+**B. Fixed Fallback Logic**
+- **File**: `src/lib/tts.ts` (lines 75-77, 156-157)
+- **Change**: Clear ElevenLabs-specific options when falling back to browser TTS
+  ```typescript
+  return this.speakWithBrowser(text, { 
+    ...options, 
+    voiceId: undefined,           // Don't pass ElevenLabs voice ID
+    stability: undefined,          // Remove ElevenLabs param
+    similarityBoost: undefined     // Remove ElevenLabs param
+  })
+  ```
+- **Impact**: Browser TTS uses system default voice instead of searching for non-existent voice
+- **Benefit**: Seamless fallback without errors
+
+**C. Browser Autoplay Policy Fix**
+- **Files**: `src/lib/tts.ts` (both `playCached()` and `speakWithElevenLabs()`)
+- **Problem**: Async operations broke user interaction chain, causing `NotAllowedError`
+- **Solution**:
+  1. Create `Audio` element **immediately** before async operations
+  2. Set `audio.src` after loading instead of `new Audio(data)`
+  3. Remove setTimeout delays
+  4. Play immediately to maintain user gesture context
+  ```typescript
+  // Create immediately (maintains user interaction context)
+  this.currentAudio = new Audio()
+  this.currentAudio.volume = volume
+  
+  // Load async...
+  const audioData = await loadAudio()
+  
+  // Set source and play immediately
+  this.currentAudio.src = base64Data
+  await this.currentAudio.play()
+  ```
+- **Impact**: First play always works, no permission errors
+- **Benefit**: Reliable, consistent audio playback
+
+**Technical Details**:
+- Browser autoplay policy requires `play()` to be called synchronously with user gesture
+- Creating Audio element immediately maintains the interaction context
+- Setting `src` later doesn't break the chain
+
+---
+
+### 2. Audio Caching System ✅
+**Status**: Production Ready  
+**Priority**: High
+
+#### Implementation
+
+**A. Rust Backend Commands**
+- **File**: `src-tauri/src/main.rs`
+- **New Functions**:
+  ```rust
+  save_audio_file(messageId, audioData) -> Result<String>
+  load_audio_file(messageId) -> Result<Vec<u8>>
+  check_audio_file(messageId) -> Result<bool>
+  delete_audio_file(messageId) -> Result<()>
+  delete_audio_files_batch(messageIds) -> Result<usize>
+  ```
+- **Storage Location**: `{app_data_dir}/audio_cache/{messageId}.mp3`
+- **Platform Support**: Cross-platform (Windows, macOS, Linux)
+
+**B. TTS Manager Integration**
+- **File**: `src/lib/tts.ts`
+- **New Methods**:
+  ```typescript
+  hasCachedAudio(messageId): Promise<boolean>
+  playCached(messageId, volume): Promise<void>
+  saveAudioToCache(messageId, audioData): Promise<void>
+  loadCachedAudio(messageId): Promise<ArrayBuffer>
+  deleteCachedAudio(messageId): Promise<void>
+  deleteCachedAudioBatch(messageIds): Promise<number>
+  ```
+- **Auto-Save**: ElevenLabs audio automatically cached after generation
+- **Lazy Loading**: Only loads when replay button is clicked
+
+**C. UI Updates**
+- **File**: `src/components/TTSControls.tsx`
+- **New States**:
+  - `hasCachedAudio` - Tracks if audio exists
+  - Checks cache on mount
+  - Updates after generation
+- **Button States**:
+  - **No cache**: Shows speaker icon (Volume2) - "Generate audio"
+  - **Has cache**: Shows two buttons:
+    - Green Play button - "Replay cached audio" (instant)
+    - Blue RotateCw button - "Regenerate audio" (overwrites)
+
+#### Benefits
+- ✅ **Instant Playback**: Cached audio plays immediately, no API call
+- ✅ **Cost Savings**: Reduces ElevenLabs API usage for repeated messages
+- ✅ **Offline Capability**: Replay audio without internet
+- ✅ **Persistent Storage**: Audio survives app restarts
+- ✅ **User Control**: Option to regenerate or replay
+
+---
+
+### 3. Chat Session Persistence ✅
+**Status**: Production Ready  
+**Priority**: High
+
+#### Implementation
+
+**A. ChatStore Persistence**
+- **File**: `src/stores/chatStore.ts`
+- **Changes**:
+  - Added Zustand `persist` middleware
+  - Storage key: `eve-chat-session`
+  - Persists: messages, model, loading state
+  - Does NOT persist: `lastAddedMessageId` (intentional)
+  
+**B. Last Added Message Tracking**
+- **File**: `src/stores/chatStore.ts`
+- **New Field**: `lastAddedMessageId: string | null`
+- **Purpose**: Track most recently added message for auto-play
+- **Lifecycle**:
+  1. Set when `addMessage()` is called
+  2. Cleared after 2 seconds (prevents re-trigger)
+  3. NOT persisted (resets on app reload)
+  4. Cleared when loading conversations
+
+**C. Message Deletion with Audio Cleanup**
+- **File**: `src/stores/chatStore.ts`
+- **New Methods**:
+  ```typescript
+  deleteMessage(id, deleteAudio = false): Promise<void>
+  clearMessages(deleteAudio = false): Promise<void>
+  ```
+- **Confirmation Flow**:
+  1. "Are you sure?" confirmation
+  2. "Also delete audio?" confirmation (OK = delete, Cancel = keep)
+  3. Batch deletion for multiple messages
+
+**D. Conversation Store Updates**
+- **File**: `src/stores/conversationStore.ts`
+- **Updated Method**:
+  ```typescript
+  deleteConversation(id, deleteAudio = false): Promise<void>
+  ```
+- **Batch Audio Deletion**: Deletes all audio files for conversation messages
+
+#### Benefits
+- ✅ **Never Lose Work**: Chats persist across restarts
+- ✅ **Storage Control**: Optional audio deletion
+- ✅ **User Informed**: Clear confirmations
+- ✅ **Efficient**: Batch operations for multiple files
+
+---
+
+### 4. Smart Auto-Play Logic ✅
+**Status**: Production Ready  
+**Priority**: High
+
+#### Problem
+When reopening the app, **all persisted messages** triggered auto-play, regenerating audio unnecessarily and causing chaos.
+
+#### Solution
+
+**A. Message ID Tracking**
+- **File**: `src/stores/chatStore.ts`
+- Track `lastAddedMessageId` (NOT persisted)
+- Only this message can auto-play
+
+**B. Auto-Play Decision**
+- **File**: `src/components/ChatMessage.tsx`
+- **Logic**:
+  ```typescript
+  const shouldAutoPlay = ttsConversationMode && message.id === lastAddedMessageId
+  ```
+- **Result**: Only newly generated messages auto-play
+
+**C. Lifecycle Management**
+- **File**: `src/components/ChatInterface.tsx`
+- Clear `lastAddedMessageId` after 2 seconds
+- Prevents re-triggers on re-renders
+- Gives TTSControls time to mount
+
+**D. Conversation Loading**
+- **File**: `src/components/ConversationList.tsx`
+- Explicitly clear `lastAddedMessageId` when loading
+- Preserves cached audio without auto-play
+
+#### Behavior Matrix
+
+| Scenario | Auto-Play | Uses Cache | Result |
+|----------|-----------|------------|---------|
+| New message (Audio Mode ON) | ✅ Yes | ❌ No | Generates & plays |
+| New message (Audio Mode OFF) | ❌ No | ❌ No | Generates, manual play |
+| App reload | ❌ No | ✅ Yes | Shows replay button |
+| Load conversation | ❌ No | ✅ Yes | Shows replay button |
+| Replay cached | ❌ No | ✅ Yes | Instant playback |
+
+#### Benefits
+- ✅ **No Chaos**: Loaded messages never auto-play
+- ✅ **Cache First**: Uses saved audio for old messages
+- ✅ **User Control**: Manual replay for historical messages
+- ✅ **Predictable**: Clear, consistent behavior
+
+---
+
+### 5. UI/UX Improvements ✅
+
+#### Confirmation Dialogs
+- **Clear Messages**: 2-step confirmation with audio deletion option
+- **Delete Conversation**: 2-step confirmation with audio deletion option
+- **User-Friendly**: "OK to delete, Cancel to keep" messaging
+
+#### Visual Indicators
+- **TTSControls States**:
+  - 🔊 Generate (no cache)
+  - ▶️ Replay (has cache, instant)
+  - 🔄 Regenerate (has cache, overwrites)
+  - ⏸️ Pause (playing)
+  - ⏹️ Stop (playing)
+
+#### Console Logging
+- Comprehensive debug logs for audio operations
+- Cache check results
+- Playback state transitions
+- Error messages with context

+
+**Example Scenarios**:
+
+**Memory**:
+```
+User: "Remember that I prefer Python over JavaScript"
+EVE: "I'll remember that!"
+
+[Later, different session]
+User: "Which language should I use for this project?"
+EVE: "Based on what I know about your preferences (you prefer Python)..."
+```
+
+**Documents**:
+```
+User: "What did the contract say about payment terms?"
+EVE: [Searches document library] "According to contract.pdf page 5..."
+```
+
+**Vision**:
+```
+User: "Create an image of a futuristic cityscape"
+EVE: [Generates image] "Here's the image. Would you like me to modify it?"
+```
