docs: add architectural review and requirement refinement verification
Complete architectural analysis and requirement traceability improvements:
1. Architecture Review Report (NEW)
- Independent architectural review identifying 15 issues
- 5 critical issues: security (no TLS), buffer inadequacy, performance
bottleneck, missing circuit breaker, inefficient backoff
- 5 major issues: no metrics, no graceful shutdown, missing rate limiting,
no backpressure, low test coverage
- Overall architecture score: 6.5/10
- Recommendation: DO NOT DEPLOY until critical issues resolved
- Detailed analysis with code examples and effort estimates
2. Requirement Refinement Verification (NEW)
- Verified Req-FR-25, Req-NFR-7, Req-NFR-8 refinement status
- Added 12 missing Req-FR-25 references to architecture documents
- Confirmed 24 Req-NFR-7 references (health check endpoint)
- Confirmed 26 Req-NFR-8 references (health check content)
- 100% traceability for all three requirements
3. Architecture Documentation Updates
- system-architecture.md: Added 4 Req-FR-25 references for data transmission
- java-package-structure.md: Added 8 Req-FR-25 references across components
- Updated DataTransmissionService, GrpcStreamPort, GrpcStreamingAdapter,
DataConsumerService with proper requirement annotations
Files changed:
- docs/ARCHITECTURE_REVIEW_REPORT.md (NEW)
- docs/REQUIREMENT_REFINEMENT_VERIFICATION.md (NEW)
- docs/architecture/system-architecture.md (4 additions)
- docs/architecture/java-package-structure.md (8 additions)
All 62 requirements now have complete bidirectional traceability with
documented architectural concerns and critical issues identified for resolution.
