## Pending ⚠️

### 1. Database Setup (30 minutes)

**Supabase PostgreSQL**
```bash
# Step 1: Go to Supabase dashboard
# Step 2: Open SQL Editor
# Step 3: Create extensions
CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
CREATE EXTENSION IF NOT EXISTS "pg_trgm";
CREATE EXTENSION IF NOT EXISTS "vector";

# Step 4: Run migration
# Copy content from: backend/db/migrations/20250130000000_init.sql
# Paste into SQL Editor and execute
```

**Neo4j Aura**
```bash
# Step 1: Go to Neo4j Browser
# Step 2: Create constraints
CREATE CONSTRAINT item_id_unique IF NOT EXISTS
FOR (i:Item) REQUIRE i.item_id IS UNIQUE;

CREATE CONSTRAINT project_id_unique IF NOT EXISTS
FOR (p:Project) REQUIRE p.project_id IS UNIQUE;

CREATE CONSTRAINT agent_id_unique IF NOT EXISTS
FOR (a:Agent) REQUIRE a.agent_id IS UNIQUE;

# Step 3: Create indexes
CREATE INDEX project_id_idx IF NOT EXISTS
FOR (n) ON (n.project_id);

CREATE INDEX type_idx IF NOT EXISTS
FOR (n) ON (n.type);

CREATE INDEX name_idx IF NOT EXISTS
FOR (n) ON (n.name);
```

### 2. Integration Testing (1-2 hours)

```bash
# Run backend
cd backend
./tracertm-backend

# In another terminal, test endpoints
curl http://localhost:8080/health
curl -X POST http://localhost:8080/api/projects \
  -H "Content-Type: application/json" \
  -d '{"name":"Test Project"}'

# Test all 49 endpoints
# Test real-time WebSocket updates
# Test search functionality
# Test graph queries
# Test caching behavior
```

### 3. Deployment (2-4 hours)

- [ ] Docker containerization
- [ ] Kubernetes manifests
- [ ] CI/CD pipeline
- [ ] Monitoring setup
- [ ] Logging setup
- [ ] Alerting setup
