Verification Levels:

1. Hash-consing: Structural equality (fastest)
2. Dependent types: Policy constraint checking
3. Theorem proving: Formal proof generation

4. Monitoring & Metrics (src/monitoring/metrics.ts)

• Threat detection by level
• Vector search performance
• Verification performance
• Cache hit rates
• Active requests gauge

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
