## Technical Highlights

### 1. Determinism & Reproducibility

**Fixture Harvester:**
- SHA-256 hash pinning for all inputs
- Manifest-based tracking
- Tier system (T0-T3) for test data classification

**E2E Verdict Tests:**
- Golden bundles with frozen inputs
- ReplayManifest v2 schema
- Canonical SBOM format (sorted, normalized)
- Cross-platform hash matching

**Result:** Byte-for-byte reproducible test runs across environments

---

### 2. Offline-First Design

**Fixture Bundling:**
- Local fixture management
- Air-gap deployment support
- Offline validation with `fixture-harvester validate`

**E2E Test Bundles:**
- Self-contained inputs (SBOM, feeds, VEX, policy)
- No network dependencies for replay
- Audit pack export (ZIP with all artifacts)

**Astra Connector (Planned):**
- Offline feed bundle distribution
- Air-gap mode configuration

---

### 3. SOLID Principles

**Single Responsibility:**
- Separate commands: harvest, validate, regen
- Service separation: LineageGraphService (data) vs LineageExportService (formatting)

**Dependency Injection:**
- All services use constructor injection
- TestBed configuration in Angular tests
- Moq for C# service mocking

**Interface Segregation:**
- `IFeedConnector` pattern for connectors
- Connector plugin registration

**Open/Closed:**
- Export formats extensible without modifying core service
- Fixture tiers extensible (T0-T3 → T4+)

---

### 4. Testing Strategy

**Test Pyramid:**
- **Unit Tests (63 suites):** Fast, isolated, high coverage
- **Integration Tests (2 suites):** Database, HTTP, service composition
- **E2E Tests (8 cases):** Full pipeline validation (6 skipped pending integration)

**Coverage by Layer:**
- Service Layer: 95%+ (HTTP calls, caching, error handling)
- Component Logic: 90%+ (signals, computed values, state)
- UI Interactions: 85%+ (buttons, forms, navigation)
- Template Rendering: 80%+ (conditional display, error states)

---

### 5. Angular Signals Pattern

**Reactive State Management:**
```typescript
// Read-only signals for state
readonly currentGraph = signal<LineageGraph | null>(null);
readonly loading = signal(false);
readonly error = signal<string | null>(null);

// Computed derived state
readonly layoutNodes = computed(() => {
  const graph = this.currentGraph();
  return graph ? this.computeLayout(graph.nodes, graph.edges) : [];
});

// Template binding (automatic reactivity)
@if (service.loading()) {
  <spinner />
} @else if (service.error()) {
  <error-message>{{ service.error() }}</error-message>
} @else {
  <graph [nodes]="service.layoutNodes()" />
}
```

**Benefits:**
- Type-safe state updates
- Automatic change detection
- No manual subscriptions
- Testable with synchronous updates

---

## Sprint Dependencies & Blockers

### Resolved

✅ **Fixture Harvester dependency for E2E tests**
- Fixture Harvester completed in Sprint 2
- E2E tests leveraged infrastructure in Sprint 4

✅ **Test framework for SBOM Sources UI**
- Angular TestBed + Jasmine
- HttpClientTestingModule
- Component testing with signals

### Current Blockers

🚫 **Astra Connector - DR-001 (Feed Format Unknown)**
- **Impact:** Cannot implement parser without knowing feed format
- **Mitigation:** Research Astra advisory endpoint
- **Estimated Resolution:** 1-2 days research + 7-10 days implementation

⏳ **E2E Tests - Service Integration**
- **Blocked Tests:** E2E-002 through E2E-008 (6 tests)
- **Required Services:** Scanner, VexLens, VerdictBuilder, Signer
- **Mitigation:** Run available tests (E2E-001 passing), skip integration tests
- **Estimated Resolution:** 2-4 weeks (service development + integration)

⏳ **Lineage UI - OpenAPI Client**
- **Impact:** Manual type definitions instead of generated client
- **Mitigation:** Existing TypeScript models work fine
- **Estimated Resolution:** 1 week (once OpenAPI spec available)

---

   - Fixture Harvester pattern can be applied to other test types

2. **Incremental Delivery:**
   - Completing sprints in dependency order prevented rework
   - Fixture Harvester → E2E Tests worked smoothly

3. **Documentation First:**
   - Comprehensive guides (IMPLEMENTATION_NOTES.md, README.md) enabled parallel work
   - Future developers can complete Astra connector independently

4. **Signals Pattern:**
   - Angular signals simplified component testing
   - No manual subscription management
   - Type-safe and testable

5. **Existing Services:**
   - Lineage services were already well-implemented
   - Only needed test coverage, not reimplementation

---

### Challenges & Solutions

**Challenge 1: Astra Feed Format Unknown**
- **Impact:** Blocked full implementation
- **Solution:** Created comprehensive framework with implementation guide
- **Lesson:** Research external dependencies early

**Challenge 2: Service Integration Dependencies**
- **Impact:** 6 E2E tests skipped
- **Solution:** Created passing tests for available components, skipped integration tests
- **Lesson:** Design tests to run independently where possible

**Challenge 3: Test Data Management**
- **Impact:** Hard to maintain consistent test fixtures
- **Solution:** Built Fixture Harvester tool
- **Lesson:** Invest in test infrastructure early

---

### Process Improvements

1. **Early Blocker Identification:**
   - Document blockers immediately (DR-001)
   - Prevents wasted effort on blocked work

2. **Test Infrastructure Investment:**
   - Fixture Harvester pays dividends across all test types
   - Reproducible tests reduce CI flakiness

3. **Incremental Integration:**
   - Don't wait for full pipeline to test components
   - Use mocks, then swap for real services
