## Service Architecture

### Layer 1: Infrastructure (No Dependencies)
- PostgreSQL @ :5432
- Redis @ :6379
- Neo4j @ :7687, :7474
- NATS @ :4222, :8222

### Layer 2: Workflow & Monitoring
- Temporal @ :7233 (depends on PostgreSQL)
- Prometheus @ :9090

### Layer 3: Exporters
- postgres_exporter @ :9187
- redis_exporter @ :9121
- node_exporter @ :9100

### Layer 4: Application Services
- Go Backend @ :8080 (Air hot reload)
- Python Backend @ :8000 (uvicorn hot reload)

### Layer 5: Gateway & Visualization
- Caddy @ :4000 (reverse proxy)
- Grafana @ :3000 (monitoring dashboards)

## Installation Status

Process Compose: ✅ Installed (v1.90.0)

Required Tools:
- ✅ PostgreSQL
- ✅ Redis
- ✅ Neo4j
- ✅ NATS
- ✅ Temporal
- ✅ Caddy
- ⚠️  Prometheus (install: brew install prometheus)
- ⚠️  Grafana (install: brew install grafana)

Exporters:
- ⚠️  postgres_exporter (install: brew install postgres_exporter)
- ⚠️  redis_exporter (install: brew install redis_exporter)
- ⚠️  node_exporter (install: brew install node_exporter)

## Make Commands Available

### Development
- `make dev` - Start all services (detached)
- `make dev-tui` - Start with interactive TUI
- `make dev-down` - Stop all services
- `make dev-logs` - View all logs
- `make dev-logs-follow SERVICE=<name>` - Follow specific service
- `make dev-restart SERVICE=<name>` - Restart service
- `make dev-status` - Show service status
- `make dev-scale SERVICE=<name> REPLICAS=<n>` - Scale service

### Monitoring
- `make grafana-dashboard` - Open Grafana
- `make prometheus-ui` - Open Prometheus
- `make metrics` - Quick metrics summary

### Installation
- `make install-native` - Install all dependencies
- `make verify-install` - Verify installation

### Utilities
- `make logs-clean` - Clean service logs
- `make data-clean` - Clean data directories (destructive!)

## Next Steps

### 1. Install Missing Dependencies (if any)

If Prometheus/Grafana/Exporters are missing:
```bash
brew install prometheus grafana postgres_exporter redis_exporter node_exporter
```

Or run the full installation:
```bash
make install-native
```

### 2. Start Services

```bash
# Interactive mode (recommended for first run)
make dev-tui

# Or detached mode
make dev
```

### 3. Verify Services

```bash
# Check status
make dev-status

# Test endpoints
curl http://localhost:5432  # PostgreSQL (should refuse - expected)
redis-cli ping              # Redis
curl http://localhost:7474  # Neo4j
curl http://localhost:8222/healthz  # NATS
curl http://localhost:4000/health   # Caddy Gateway
```

### 4. Access Monitoring

- Prometheus: http://localhost:9090
- Grafana: http://localhost:3000 (admin/admin)

## Known Issues

1. **Process Compose config warning** - Non-fatal, Process Compose works without config file
2. **Exporters may need manual installation** - Run: `brew install postgres_exporter redis_exporter node_exporter`

## Performance Expectations

**Estimated Resource Usage:**
- Memory: ~800MB-1.2GB (vs ~3.5GB with Docker)
- Startup: ~8-12 seconds cold, ~3-5 seconds warm
- CPU: Minimal idle usage

## Rollback

If needed, Docker Compose still exists at `docker-compose.yml`.

To rollback:
```bash
make dev-down           # Stop native services
docker-compose up -d    # Start Docker
```
