✅ Key Decisions Made​

1. Keep Our LangGraph Framework ✅​

Why: Already production-ready, excellent agent orchestration
Don't: Rebuild with Rasa-only or other frameworks

2. Add Rasa for Conversational AI ✅​

Why: Industry-standard intent recognition and dialogue management
Don't: Build custom NLU from scratch

3. Use Chainlit for Production UI ✅​

Why: Built for LangGraph, production-ready, easy deployment
Don't: Build custom UI from scratch initially

4. Keep Our Memory System ✅​

Why: Already production-ready, excellent performance
Don't: Replace with external conversation DB

5. Add Multi-Channel Gradually ✅​

Why: Start with Web + Slack + Telegram, expand later
Don't: Try to support all channels from day 1

6. Use OpenAI APIs for Voice ✅​

Why: Best quality, with offline fallback options
Don't: Build custom STT/TTS initially
