**Core Backend Services (100%):**
- Projects, Items, Links - Full CRUD ✅
- Graph analysis - 11 algorithms ✅
- Search - Full-text + vector + hybrid ✅
- Agent CRUD - Registration + coordination ✅

**Infrastructure (90%):**
- PostgreSQL - Active, 47+ handler refs ✅
- Redis - Caching, 56+ refs ✅
- NATS - Events, 30+ refs ✅
- Neo4j - Optional graph ops ✅

**Database (95%):**
- 48 migrations all exist ✅
- All tables created ✅
- 45/48 reversible ✅

### ❌ What Doesn't Work (Broken)

**Equivalence Service (55%):**
- 6 critical bugs prevent usage
- 10 handler methods return empty/hardcoded data
- CreateCanonicalConcept doesn't save to database

**Journey Service (44%):**
- Detector initialized as nil
- All detection endpoints return empty arrays
- No persistence layer

**Temporal Service (0%):**
- All 16 endpoints return HTTP 501
- Repositories not wired

## 💡 Key Insights

### Architecture is Excellent
- Clean service separation
- Well-designed type system
- Proper caching + event patterns
- 43+ production-ready frontend components

### Implementation is 60% Complete
- Core CRUD: 100%
- Advanced features: 0-55%
- Test coverage: 35% (uneven)

### Main Problem: Repository Layer
- Services designed well
- Handlers exist
- **Repositories not wired** → nil pointers → stubs

### Quick Wins Available
- WebSocket auth: 4-6 hours fixes security
- Wire temporal repos: 2-3 days unlocks 16 endpoints
- Initialize journey detector: 1 day unlocks detection
