Export Formats:
- Prometheus text format
- 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
