Implementation Summary

✅ Completed Features

Backend (main.py)

• Isolated Character Sessions: Each character has a separate conversation history that only they and the storyteller can see
• Private WebSocket Channels:
  • /ws/character/{session_id}/{character_id} - Character's private connection
  • /ws/storyteller/{session_id} - Storyteller's master connection
• Message Routing: Messages flow privately between storyteller and individual characters
• Scene Broadcasting: Storyteller can narrate scenes visible to all characters
• Real-time Updates: WebSocket events for character joins, messages, and responses
• Pending Response Tracking: System tracks which characters are waiting for storyteller responses
• AI Suggestions (Optional): Endpoint for AI-assisted storyteller response generation

Frontend Components

1. SessionSetup.js

• Create new session (storyteller)
• Join existing session (character)
• Character creation with name, description, and personality
• Beautiful gradient UI with modern styling

2. CharacterView.js

• Private chat interface with storyteller
• Real-time message delivery via WebSocket
• Scene narration display
• Conversation history preservation
• Connection status indicator

3. StorytellerView.js

• Dashboard showing all characters
• Character list with pending response indicators
• Click character to view their private conversation
• Individual response system for each character

• Clear visual hierarchy
• Mobile-friendly layout

Documentation

• README.md: Comprehensive guide with architecture, features, and API docs
• QUICKSTART.md: Fast setup and testing guide
• .env.example: Environment variable template

🔐 Privacy Implementation

The core requirement - isolated character sessions - is implemented through:

1. Separate Data Structures: Each character has conversation_history: List[Message]
2. WebSocket Isolation: Separate WebSocket connections per character
3. Message Routing: Messages only sent to intended recipient
4. Storyteller View: Only storyteller can see all conversations
5. Scene Broadcast: Shared narrations go to all, but conversations stay private

🎯 Workflow

Character A → Storyteller: "I search the room"
Character B → Storyteller: "I attack the guard"
    ↓
Storyteller sees both messages separately
    ↓
Storyteller → Character A: "You find a hidden key"
Storyteller → Character B: "You miss your swing"
    ↓
Character A only sees their conversation
Character B only sees their conversation

🚀 To Run

Backend:

python main.py

Frontend:

cd frontend && npm start

🎨 Design Decisions

1. WebSocket over REST: Real-time bidirectional communication required for instant message delivery
2. In-Memory Storage: Simple session management; can be replaced with database for production
3. Component-Based Frontend: Separate views for different roles (setup, character, storyteller)
4. Message Model: Includes sender, content, timestamp for rich conversation history
5. Pending Response Flag: Helps storyteller track which characters need attention

🔮 Future Enhancements

• Database persistence (PostgreSQL/MongoDB)
• User authentication
• Character sheets with stats
• Dice rolling system
• Voice/audio support
• Mobile apps
• Multi-storyteller support
• Group chat rooms (for party discussions)
