+
+**Endpoints**:
+- `GET /health` - Health status

+- Active requests gauge
+
+**Export Formats**:

+- JSON snapshots
+- Real-time statistics
+
+### 5. Type Definitions (`src/types/index.ts`)
+**341 lines** - Comprehensive TypeScript types
+
+**Type Categories**:
+- Request/Response types
+- AgentDB types (threats, incidents, vector search)
+- lean-agentic types (policies, proofs, verification)
+- Monitoring types (metrics, health)
+- Configuration types
+- Zod schemas for validation
+
+### 6. Configuration Management (`src/utils/config.ts`)
+**115 lines** - Environment-based configuration
+
+**Configuration Sections**:
+- Gateway settings (port, host, timeouts)
+- AgentDB settings (HNSW, QUIC, memory)
+- lean-agentic settings (verification features)
+- Logging configuration
+- Validation with Zod schemas
