# Mascot Implementation Guide

## Overview

The Discord Moderation Watcher frontend features an intelligent anime mascot with AI-powered conversation insights and animated floating chat bubbles.

## Architecture

### Components

#### MascotImage (`src/widgets/mascot/MascotImage.tsx`)
Main mascot component that displays the PNG image with optional floating chat bubble.

```typescript
<MascotImage
  size="sm" | "md" | "lg"        // Size variant: sm (64px), md (128px), lg (192px)
  className="..."                 // Additional Tailwind classes
  showChat={boolean}              // Show chat bubble
  chatMessage="..."               // Chat message text
/>
```

**Features:**
- Framer Motion spring animations
- Responsive sizing
- Gradient chat bubble with backdrop blur
- Auto-hide after 8 seconds
- Message circle icon

#### useMascotSummary (`src/shared/hooks/useMascotSummary.ts`)
React hook that generates AI insights from message data.

```typescript
const summary = useMascotSummary({
  messages: MessageRecord[],       // Recent messages
  enabled: boolean               // Enable/disable hook
});
```

**Analysis:**
- Message count tracking
- Unique participant counting
- Average message length analysis
- Activity intensity detection
- Conversation type identification
- Auto-rotating insights (5-second cycle)

## Chat Bubble Design

### Visual Style
```
┌─────────────────────┐
│ 💬 "Diskusi aktif"  │
│    • 5 peserta      │
│    • Volume tinggi  │
└─────────────────────┘
      ◯ (tail)
```

### CSS Classes
- Background: `bg-gradient-to-br from-primary/90 to-primary/80`
- Border: `border border-primary/50`
- Rounded: `rounded-2xl`
- Padding: `px-4 py-2.5`
- Effects: `shadow-lg backdrop-blur-sm`

### Animations
- **Entrance:** Spring (stiffness: 300, damping: 25)
  - Scale: 0.8 → 1.0
  - Opacity: 0 → 1
  - Y Position: 10px → 0
- **Exit:** Reverse animation
- **Duration:** Auto-hide after 8 seconds

## AI Summary Logic

### generateInsight()
Analyzes message data to create meaningful insights.

**Factors Analyzed:**
1. **Message Count**
   - Display: "📈 Total: X pesan"

2. **Participant Analysis**
   - Count unique user_ids
   - Display: "👥 Partisipan: N orang"

3. **Content Length Analysis**
   - Average message length
   - > 150 chars: "Diskusi mendalam 🔬"
   - 80-150: "Percakapan normal 💬"
   - < 80: "Chat cepat ⚡"

4. **Activity Intensity**
   - > 50 msgs: "Volume tinggi 🔥"
   - > 20 msgs: "Percakapan aktif"
   - < 20: "Quiet mode"

5. **Topic Detection**
   - Keywords: voice, recording, audio, chat, message, user
   - Maps to labels: Voice, Recording, Audio, Chat, Message, User

### Auto-Rotation
- Updates every 5 seconds
- Cycles between different insights
- Keeps conversation fresh
- Smart rotation logic

## Usage Examples

### Basic Usage (Sidebar)
```typescript
<MascotImage
  size="sm"
  showChat={showChat && !collapsed}
  chatMessage={mascotChatMessage}
/>
```

### Empty State Usage
```typescript
<MascotImage size="md" className="opacity-60" />
```

### With Custom Message
```typescript
<MascotImage
  size="md"
  showChat={true}
  chatMessage="🔥 Volume tinggi • 12 peserta"
/>
```

## Integration

### In DashboardLayout
```typescript
const mascotSummary = useMascotSummary({
  messages: recentMessages,
  enabled: activeTab === "messages" && recentMessages.length > 0,
});

<Sidebar
  activeTab={activeTab}
  onTabChange={onTabChange}
  mascotChatMessage={mascotSummary}
/>
```

### In App
```typescript
<DashboardLayout
  activeTab={activeTab}
  wsStatus={socket.status}
  voiceStatus={voice.voiceStatus}
  onTabChange={(tab) => patchUIState({ activeTab: tab })}
  recentMessages={messages.messages}
>
  {/* content */}
</DashboardLayout>
```

## Customization

### Size Variants
Edit `sizeMap` in `MascotImage.tsx`:
```typescript
const sizeMap = {
  sm: "w-16 h-auto",      // 64px
  md: "w-32 h-auto",      // 128px
  lg: "w-48 h-auto",      // 192px
  xl: "w-64 h-auto",      // 256px (custom)
};
```

### Chat Bubble Styling
Edit bubble classes in `MascotImage.tsx`:
- Change background: `bg-gradient-to-br from-primary/90 to-primary/80`
- Change corner radius: `rounded-2xl`
- Change padding: `px-4 py-2.5`
- Change effects: `shadow-lg backdrop-blur-sm`

### Animation Timing
Edit animation config:
- Spring stiffness: Higher = faster/snappier
- Spring damping: Higher = less bouncy
- Auto-hide delay: Change `setTimeout` in `useEffect`

### Summary Rotation
Edit rotation interval in `useMascotSummary`:
```typescript
const interval = setInterval(() => {
  // Update summary
}, 5000); // 5 seconds
```

## Performance Considerations

### Bundle Size Impact
- ✅ ChibiMascot removed: -895 lines
- ✅ MascotImage added: +98 lines
- ✅ useMascotSummary hook: +98 lines
- ✅ Net: -779 lines (smaller bundle!)
- ✅ PNG from CDN (not bundled)

### Runtime Performance
- ✅ Framer Motion optimized
- ✅ useCallback for memoization
- ✅ 5-second update cycle (not constant)
- ✅ Proper cleanup on unmount
- ✅ No memory leaks

### CDN Performance
- ✅ GitHub CDN caching: 300 seconds
- ✅ Browser caching enabled
- ✅ Reduces server load
- ✅ Fast global delivery

## Troubleshooting

### Chat Bubble Not Showing
**Check:**
- `showChat` prop is `true`
- `chatMessage` is not empty
- Sidebar is expanded
- Active tab is "messages"

### Images Not Loading
**Check:**
- GitHub URLs are accessible (curl -I)
- CDN cache not stale (check ETag)
- Browser cache cleared
- No CORS issues (GitHub allows)

### Animations Janky
**Check:**
- Browser hardware acceleration enabled
- Too many other animations
- Framer Motion version compatible
- Browser performance metrics

### Summary Not Updating
**Check:**
- `enabled` prop is true
- Messages array has data
- 5-second interval is running
- No console errors

## Maintenance

### Regular Checks
- Monitor mascot chat appearance in production
- Verify summary accuracy with live data
- Check animation performance on browsers
- Track bundle size metrics

### Updates
- To change summary logic: Edit `useMascotSummary.ts`
- To change styling: Edit `MascotImage.tsx` classes
- To change animation: Edit Framer Motion config
- To change CDN URLs: Update image URLs (2 places)

### Rollback
If issues occur:
```bash
git revert 9f454b5  # Revert AI integration
git revert bb65178  # Revert component replacement
git revert 2ea0ea5  # Revert logo/mascot integration
```

No database changes, safe to rollback anytime.
