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.

# Critical Issues - RESOLVED
|
|
|
|
## Status: ✅ ALL CRITICAL ISSUES RESOLVED
|
|
|
|
Date Resolved: 2025-11-19
|
|
|
|
---
|
|
|
|
## Issue 1: Buffer Size Conflict ✅ RESOLVED
|
|
|
|
### Original Issue
|
|
- **Req-FR-26** stated: "max 300 messages"
|
|
- **Configuration Spec** stated: "max_messages: 300000"
|
|
- **Impact**: 1000x difference affecting memory and system behavior
|
|
|
|
### Resolution
|
|
**Stakeholder Decision**: Buffer size confirmed as **300 messages**
|
|
|
|
### Changes Made
|
|
1. ✅ Updated `requirements/HSP_Configuration_File_Specification.md` line 31:
|
|
- Changed: `"max_messages": 300000`
|
|
- To: `"max_messages": 300`
|
|
|
|
2. ✅ Requirement confirmed:
|
|
- **Req-FR-26**: "If gRPC transmission fails, HSP shall buffer collected data in memory (max 300 messages)."
|
|
|
|
### Impact Assessment
|
|
- **Memory Usage**: With 300 messages max @ ~1MB each = ~300MB max buffer
|
|
- **System Behavior**: FIFO overflow with 300 message capacity
|
|
- **Architecture**: No changes needed, designed for this capacity
|
|
- **Status**: Consistent across all documentation
|
|
|

|
|
|
|
## Issue 2: Duplicate Requirement IDs ✅ RESOLVED
|
|
|
|
### Original Issues
|
|
|
|
#### 2.1 Req-FR-25 (Duplicate)
|
|
- **Line 66**: "HSP shall then send the collected and aggregated data to the CollectorSender Core as decribed below."
|
|
- **Line 67**: "If gRPC transmission fails, HSP shall buffer collected data in memory (max 300 messages)."
|
|
|
|
**Resolution**: Renumbered line 67 and subsequent requirements
|
|
- Line 67: Now **Req-FR-26** (buffer 300 messages)
|
|
- Line 68: Now **Req-FR-27** (discard oldest) - was Req-FR-26
|
|
- Lines 70-75: Renumbered Req-FR-28 through Req-FR-33
|
|
|
|
#### 2.2 Testing Requirements (Req-NFR-7, Req-NFR-8 duplicates)
|
|
- **Lines 117-118**: Duplicate Req-NFR-7 and Req-NFR-8 in Testing Requirements section
|
|
- **Lines 119-120**: Req-NFR-9 and Req-NFR-10 also in Testing section
|
|
|
|
**Resolution**: Created new Testing Requirements category
|
|
- **Req-Test-1**: Integration tests shall verify HTTP collection with a mock HTTP server
|
|
- **Req-Test-2**: Integration tests shall verify gRPC transmission with a mock gRPC server
|
|
- **Req-Test-3**: Tests shall use JUnit 5 and Mockito frameworks
|
|
- **Req-Test-4**: All tests shall be executable via 'mvn test' command
|
|
|
|
#### 2.3 User Stories (Req-US-1 triplicate)
|
|
- **Lines 126-128**: All three user stories labeled as Req-US-1
|
|
|
|
**Resolution**: Renumbered user stories
|
|
- **Req-US-1**: System operator story (automatic data collection)
|
|
- **Req-US-2**: Data analyst story (reliable gRPC transmission)
|
|
- **Req-US-3**: System administrator story (health check monitoring)
|
|
