[AUDIT] Complete OpenAPI CRUD Operations

OpenAPI-First Architecture Audit

Severity: MEDIUM

Current Status

• OpenAPI 3.1 spec exists (479 lines)
• Basic health endpoint documented
• Gateway operations defined

Missing CRUD Operations

Audit required for complete CRUD coverage:

• Gateway configurations (C/R/U/D)
• Route definitions (C/R/U/D)
• Provider configurations (C/R/U/D)
• Rate limit rules (C/R/U/D)
• Circuit breaker configs (C/R/U/D)

Required Actions

1. Audit OpenAPI spec for missing CRUD operations
2. Define missing operations in OpenAPI spec
3. Generate types from spec
4. Generate Zod schemas for validation
5. Implement controllers (thin)
6. Implement services (business logic)
7. Implement repositories (data layer)
8. Write tests (TDD - tests first!)

Definition of Done

• All resources have full CRUD operations
• OpenAPI spec is single source of truth
• Types generated from spec
• Zod validation on all inputs/outputs
• 100% test coverage on CRUD operations
