ARCHITECTURE INSIGHTS
================================================================================

Monolithic Component Structure:
- Gateway (Caddy) routes all requests to 3 backend services
- Go backend: High-performance services (graph, analysis, auth)
- Python backend: Domain logic (items, links, tests, integrations, AI)
- Frontend: React SPA with TypeScript

API Distribution:
- 49% endpoints in Gateway (routing layer)
- 38% endpoints in Python (domain services)
- 12% endpoints in Go (core infrastructure)

Complexity Pattern:
- Very Complex Features (50+ endpoints): Projects (98), Integrations (60)
- Complex Features (15-50 endpoints): 10 features
- Moderate Features (8-15 endpoints): 8 features
- Simple Features (<8 endpoints): 10 features

Test Distribution:
- Repository layer: Excellent (35 files)
- API/Integration: Strong (50+ files)
- Security: Good (7 files)

Step 3: Test Coverage Mapping
  - Globbed for test files across 3 main directories
  - Categorized tests by type (unit, integration, E2E)
  - Mapped tests to feature areas
  - Calculated coverage ratios

Step 4: Gap Analysis
  - Identified features with zero test coverage
  - Flagged under-tested areas (<30% coverage)
  - Prioritized missing test categories
  - Created recommendations

Step 5: Documentation Generation
  - Created comprehensive extraction report
  - Built quick reference guide
  - Developed test coverage matrix
  - Generated actionable recommendations
