|
|
| **Total Requirements** | 62 | |
|
|
| **Fully Implemented** | 42 (68%) | 🟢 |
|
|
| **Partially Implemented** | 16 (26%) | 🟡 |
|
|
| **Missing** | 4 (6%) | 🔴 |

|
|
| **Production Ready** | NO | ❌ |
|
|
|
|

|
|
|
|
## 🔴 Critical Missing Requirements (MUST FIX)
|
|
|
|
### 1. **Req-FR-4**: gRPC Connection at Startup
|
|
**Status**: ❌ **MISSING**
|
|
**Impact**: System may start without backend connectivity
|
|
**Evidence**: No explicit `connect()` call in startup sequence
|
|
**Fix**: Add gRPC connection establishment in `LifecycleController` startup
|
|
|
|
### 2. **Req-FR-7**: Wait for gRPC Before HTTP Polling
|
|
**Status**: ❌ **MISSING**
|
|
**Impact**: Data collected before transmission ready (data loss)
|
|
**Evidence**: No blocking logic in startup sequence
|
|
**Fix**: Add wait condition: `while (!grpcConnected) { sleep(100ms); }`
|
|
|
|
### 3. **Req-FR-8**: "HSP started successfully" Log Message
|
|
**Status**: ❌ **MISSING**
|
|
**Impact**: No confirmation of successful startup
|
|
**Evidence**: Searched codebase - message not found
|
|
**Fix**: Add `logger.info("HSP started successfully")` after startup complete
|
|
|
|
### 4. **Req-NFR-6**: Fat JAR Packaging
|
|
**Status**: ❌ **MISSING**
|
|
**Impact**: Cannot deploy as executable JAR
|
|
**Evidence**: No maven-shade-plugin or assembly-plugin in `pom.xml`
|
|
**Fix**: Add packaging plugin to Maven configuration
|
|
|
|
---
|
|
|
|
## ⚠️ High Priority Partial Implementations (SHOULD FIX)
|
|
|
|
### 5. **Req-FR-18**: Linear Backoff Strategy
|
|
**Status**: ⚠️ **PARTIAL** (Only fixed 5s retry, no backoff progression)
|
|
**Impact**: Inefficient retry strategy
|
|
**Fix**: Implement `delay = min(5 + (attempt * 5), 300)` seconds
|
|
|
|
### 6. **Req-FR-29**: gRPC Stream Disconnect on Shutdown
|
|
**Status**: ⚠️ **PARTIAL** (Tests show `disconnect()` not called)
|
|
**Impact**: Resource leaks on shutdown
|
|
**Fix**: Ensure `disconnect()` called in shutdown sequence
|
|
|
|
### 7. **Req-FR-31/32**: 4MB Batch Size & 1s Latency
|
|
**Status**: ⚠️ **PARTIAL** (Test `shouldNotExceed4MBBatchSize` FAILS)
|
|
**Impact**: May violate batching requirements
|
|
**Fix**: Debug batch accumulation algorithm in `DataTransmissionService`
|
|
|
|
### 8. **Req-Arch-6**: Virtual Threads for Consumer
|
|
**Status**: ⚠️ **PARTIAL** (HTTP uses virtual threads, gRPC consumer does not)
|
|
**Impact**: Performance bottleneck with 1000 endpoints
|
|
**Fix**: Change consumer from `new Thread()` to virtual thread executor
|
|
|
|
### 9. **Req-Test-4**: All Tests Passing
|
|
**Status**: ⚠️ **PARTIAL** (58.8% pass rate vs. 100% required)
|
|
**Impact**: Cannot verify system correctness
|
|
**Fix**: Fix 122 failing tests systematically
|
|
|
|
### 10. **Req-Norm-2**: EN 50716 Safety Compliance
|
|
**Status**: ⚠️ **PARTIAL** (No TLS, test coverage 58.8% vs. 95% required)
|
|
**Impact**: Cannot certify for safety-critical use
|
|
**Fix**: Add TLS encryption, raise test coverage to 95%/90%

## 🚨 Deployment Blockers
|
|
|
|
### Cannot Deploy Until Fixed:
|
|
|
|
1. **Missing Startup Sequence** (FR-4, FR-7, FR-8)
|
|
- System may start in invalid state
|
|
- No backend connectivity verification
|
|
- No success confirmation
|
|
|
|
2. **No Deployable Artifact** (NFR-6)
|
|
- Cannot package as fat JAR
|
|
- Manual dependency management required
|
|
|
|
3. **Test Failure Rate: 41%** (Test-4)
|
|
- Cannot verify correctness
|
|
- High risk of production bugs
|
|
|
|
4. **Resource Leaks** (FR-29)
|
|
- gRPC connections not closed
|
|
- Memory/connection leaks on restart
|
|
|
|
5. **Batch Size Violations** (FR-31/32)
|
|
- May exceed 4MB limit
|
|
- May violate 1s latency requirement
|
