## Quality Metrics Dashboard

### Per-Gap Success Criteria

| Gap | Tests | Coverage | Performance | Accessibility |
|-----|-------|----------|-------------|---------------|
| 5.1 | 8+ | 85%+ | <5% regression | N/A |
| 5.2 | 5+ | 80%+ | N/A | N/A |
| 5.3 | 8+ | 85%+ | N/A | N/A |
| 5.4 | 1+ | 90%+ | N/A | N/A |

| 5.8 | 8+ | 95%+ | <5% regression | N/A |
| **Total** | **80+** | **90%+** | **All targets** | **AA compliant** |

### Quality Score Calculation (Target: 97-98/100)

**Weighting:**
- Test Coverage (30%): 90%+ = 28-30 pts
- Performance (25%): All targets met = 24-25 pts
- Accessibility (15%): WCAG AA = 14-15 pts
- Code Quality (20%): Linting + types = 19-20 pts
- Documentation (10%): Guides + API = 9-10 pts

**Total:** 94-100 pts (targeting 97-98)

- 256-thread workgroups for parallelization
- 50-100x speedup target

**WebGL Fallback:**
- Fragment shader GPGPU via texture framebuffer
- 20-50x speedup for older devices
- Full fallback chain tested

**CPU Fallback:**
- Existing D3-force implementation
- Tested on all platforms

### Gap 5.8: Spatial Indexing
**Implementation:**
- Extend RTreeItem with midpointX/midpointY
- Add getEdgeDistanceToViewportCenter() method
- Distance-based LOD culling thresholds

**Metrics:**
- Culling accuracy: 85% → 98%
- Memory overhead: <5% (24→28 bytes)
- Performance regression: <5%

### Gap 5.4: Temporal Service
**Workflow Pattern:**
- Query activity (fetch data)
- Create activity (process snapshot)
- Upload activity (save to MinIO)
- Simple, tested, extensible

## Risk Mitigation

### All Critical Risks Addressed

| Risk | Mitigation |
|------|-----------|
| GPU shader compilation fails | MSW mocks for CI; test on multiple browsers |
| NATS connectivity | Docker Compose for test env; error messages |
| Temporal workflow complexity | Start simple; iterative enhancement |
| Visual regression flakiness | Seed randomness; run 5x; exclude timing |
| Memory leaks (GPU) | Explicit cleanup; resource tracking |
| E2E timeout | Increased timeouts; parallel execution |
