### Avatar System (Exact V1 Match)

#### User Avatar
- **Source**: Vercel avatar service `https://avatar.vercel.sh/${userEmail}`

- **Fallback**: Generated avatar based on email

#### Assistant Avatar
- **Source**: Actual Papr logo SVG from v1 (blue gradient feather)
- **Size**: 16x16px icon in 32x32px container
- **Container**: Ring border + background (matches v1)

### Layout (Exact V1 Match)
```
flex items-start gap-3
├── Avatar (32x32px, flex-shrink-0)
└── Content (flex-1, flex-col, gap-3)
     ├── ThinkingCard (if reasoning)
     ├── ActioningCards (if tool calls)
     └── Message text
```

### What Was Removed
- ❌ Emoji icons (👤 🤖)
- ❌ Message role labels
- ❌ Background colors on messages
- ❌ User/assistant name display (v1 doesn't show names)

### Files Changed
- `ui/components/Chat/MessageItem.tsx` - Updated avatar rendering
- `ui/components/Chat/MessageItem.css` - V1-matched styles
- `ui/public/images/papr-logo.svg` - Copied actual v1 logo

---

## 6. Streaming Enhancement ✅

### Type System
Updated `ui/types/core.ts` with:
```typescript
interface ToolCall {
  id: string;
  toolName: string;
  args?: Record<string, unknown>;
  status: "calling" | "success" | "error";
  result?: string;
  error?: string;
}

interface CoreMessage {
  // ... existing
  reasoning?: string;
  streamingReasoning?: string;
  toolCalls?: ToolCall[];
}
```

### Streaming Handler
Enhanced `ui/hooks/useAgent.ts`:
- Added `streamingReasoningRef` for reasoning accumulation
- Added `toolCallsMapRef` for tool call tracking
- New chunk handlers:
  - `reasoning-delta` - Appends reasoning text
  - `tool-call` - Creates/updates tool with "calling" status
  - `tool-result` - Updates tool with result/error

## Known Issues & Next Steps

### Backend TODOs
1. **Tool Result Chunks**: MastraAgent needs to emit `tool-result` chunks
   - Currently only emits `tool-call`
   - Need to track tool execution completion
   - Should include execution time

2. **Reasoning Chunks**: Verify Mastra emits `reasoning-delta`
   - Test with Claude Sonnet 4.5 extended thinking
   - Test with Gemini 2.5 Pro thinking

### Frontend TODOs
3. **User Session**: Replace hardcoded email with actual user info
   - Option 1: Store in Electron settings
   - Option 2: Use system username
   - Option 3: Add user settings UI

4. **Markdown Rendering**: Add markdown support for:
   - Thinking card content
   - Tool result text
   - Main message text

5. **Tool Call Grouping**: Implement collapsible tool groups like v1

6. **Accessibility**:
   - Add ARIA labels
   - Keyboard navigation
   - Screen reader support

---

## Performance Notes

- Model picker dropdown: Smooth 150ms animation
- Thinking card expand: 200ms fadeIn
- Actioning card appear: 200ms slideIn
- All animations use `var(--ease)` for consistency
- Z-index properly layered (dropdown at 10000)

---

## How to Test

1. **Reload the app**: Press `Cmd+R` in Electron window
2. **Send a test message**: Click in input, type, send
3. **Try model picker**: Click model selector button
4. **Check console**: Look for "Model picker clicked" logs
5. **Verify avatars**: User should show generated avatar, assistant shows Papr logo
6. **Test thinking**: Use Claude Sonnet 4.5 for reasoning (if available)

---

## Success Metrics ✅

- [x] Build with no errors
- [x] No linter errors
- [x] All types properly defined
