## Implementation Phases

### Phase 1: MVP (Weeks 1-2)
✅ Backend: Supabase, NATS, Redis
✅ Frontend: Board, Table, Graph views
✅ Search: Basic integration
✅ Deploy: Railway + Vercel

### Phase 2: Enhanced (Weeks 3-4)
⏳ Backend: Meilisearch, event sourcing
⏳ Frontend: Timeline, Hierarchy, Roadmap views
⏳ Real-time: Collaboration features

### Phase 3: Analytics (Weeks 5+)
⏳ Backend: Neo4j integration
⏳ Frontend: Analytics dashboard
⏳ Reports: Traceability matrix

---

## Key Decisions

### ✅ PostgreSQL (Supabase)
- Handles all requirements
- Mature, proven
- pgvector for semantic search
- Full-text search
- Event sourcing

### ✅ NATS (Synadia Cloud)
- Agent coordination
- Sub-millisecond latency
- JetStream persistence
- Generous free tier

### ✅ Redis (Upstash)
- Serverless (no cold starts)
- Caching + sessions
- Pub/sub for real-time
- Generous free tier

### ✅ Meilisearch
- Better than PostgreSQL FTS
- Typo tolerance
- Faceted search
- Open source

### ❌ NOT Neo4j (Primary)
- Expensive
- Overkill for MVP
- Add as optional Phase 2+

### ❌ NOT SurrealDB/ArangoDB/EdgeDB
- Too immature
- PostgreSQL handles all use cases

### ❌ NOT Elasticsearch
- PostgreSQL FTS sufficient
- Add later if needed

### ❌ NOT Kafka
- NATS provides all needed messaging
- Simpler, faster
