- pgvector RAG knowledge base (95 FAQ chunks)
- Auto opportunity creation in Twenty CRM
- Auto follow-up task workflow
- Chatwoot AgentBot integration (HMAC, webhook)
- Docker compose infrastructure (PG18, Redis 8.8, node24-alpine)
- Configuration templates (example files) - real secrets excluded via .gitignore
