```

**Note:** Pre-existing build errors in `PredicateSchemaValidator.cs` need to be resolved (missing Json.Schema NuGet package).

---

## Testing

### Unit Tests

All components include `.spec.ts` test files. Run with:

```bash
cd src/Web/StellaOps.Web
ng test
```

### E2E Tests

Placeholder test structure created. Implement with Playwright or Cypress:

```bash
# Using Playwright (recommended)
npm install -D @playwright/test
npx playwright test

# Or using Cypress
npm install -D cypress
npx cypress open
```

- [x] Create backend services (2 services, 1 controller)
- [x] Add routing configuration
- [x] Register services in DI container
- [ ] Install Cytoscape.js (`npm install cytoscape @types/cytoscape`)
- [ ] Fix pre-existing build error in PredicateSchemaValidator.cs
- [ ] Run `ng build` to verify compilation
- [ ] Run `dotnet build` for backend
- [ ] Write comprehensive unit tests
- [ ] Add E2E test scenarios

### Configuration

```

#### appsettings.json (Attestor)

Ensure proof chain services are configured:

```json

    "quotas": {
      "perCaller": {
        "qps": 10,
        "burst": 20
      }

## Usage Examples

### Case Header Component

```typescript
import { CaseHeaderComponent, CaseHeaderData } from '@app/features/triage/components/case-header';

const data: CaseHeaderData = {
  verdict: 'ship',
  findingCount: 10,
  criticalCount: 2,
  highCount: 5,
  actionableCount: 7,
  deltaFromBaseline: {
    newBlockers: 0,
    resolvedBlockers: 2,
    newFindings: 3,
    resolvedFindings: 1,
    baselineName: 'v1.2.0'
  },
  attestationId: 'att-123',
  snapshotId: 'ksm:sha256:abc123',
  evaluatedAt: new Date()
};

// In template
<stella-case-header
  [data]="data"
  (verdictClick)="onVerdictClick()"
  (attestationClick)="viewAttestation($event)"
  (snapshotClick)="viewSnapshot($event)">
</stella-case-header>
```

### Verdict Ladder Component

```typescript
import { VerdictLadderComponent, VerdictLadderData } from '@app/features/triage/components/verdict-ladder';
import { VerdictLadderBuilderService } from '@app/features/triage/services/verdict-ladder-builder.service';

// Build steps using the service
const steps = [
  this.ladderBuilder.buildDetectionStep(detectionEvidence),
  this.ladderBuilder.buildComponentStep(componentEvidence),
  this.ladderBuilder.buildApplicabilityStep(applicabilityEvidence),
  // ... other steps
];

const ladderData: VerdictLadderData = {
  findingId: 'CVE-2024-1234',
  steps,
  finalVerdict: 'ship'
};

// In template
<stella-verdict-ladder [data]="ladderData"></stella-verdict-ladder>
```

### Compare View Component

```typescript
// Navigate to compare view
this.router.navigate(['/compare', currentArtifactId], {
  queryParams: { baseline: 'last-green' }
});
```

### Proof Chain Component

```typescript
// Navigate to proof chain view
this.router.navigate(['/proofs', subjectDigest]);
```

---

## API Integration

### Proof Chain API

```typescript
import { ProofChainService } from '@app/features/proof-chain/proof-chain.service';

// Get proof chain
const chain = await this.proofChainService.getProofChain(subjectDigest);

// Get specific proof
const proof = await this.proofChainService.getProof(proofId);

// Verify proof
const result = await this.proofChainService.verifyProof(proofId);
```

### Backend API Usage

```bash
# Get proof chain for an artifact
GET /api/v1/proofs/{subjectDigest}/chain
Authorization: Bearer <token>

# Verify a proof
GET /api/v1/proofs/id/{proofId}/verify
Authorization: Bearer <token>
```

---

## Deployment

### Air-Gapped Environment

1. **Build offline bundle:**
   ```bash
   cd src/Web/StellaOps.Web
   ng build --configuration production

   # Package node_modules
   npm pack
   ```

2. **Bundle backend:**
   ```bash
   cd src/Attestor/StellaOps.Attestor
   dotnet publish -c Release -r linux-x64 --self-contained
   ```

3. **Transfer to air-gapped environment**

4. **Deploy:**
   - Extract and serve Angular build from `dist/`
   - Run .NET self-contained executable
   - Ensure PostgreSQL is available

### Docker Deployment

See `docs/install/docker.md` for containerized deployment.

## Known Issues

1. **Pre-existing build error:** `PredicateSchemaValidator.cs` has missing Json.Schema references (not related to Sprint 4200 work)
2. **Cytoscape.js not installed:** Run `npm install cytoscape @types/cytoscape` before building
3. **No backend API mocks:** Integration tests need mock API responses

---

## Next Steps

1. **Fix build errors:** Resolve PredicateSchemaValidator.cs dependencies
2. **Install Cytoscape.js:** `npm install cytoscape @types/cytoscape`
3. **Run full build:** `ng build && dotnet build`
4. **Write tests:** Add comprehensive unit and E2E tests
5. **Add API mocks:** Create mock data for offline development
6. **Documentation:** Add user guides with screenshots
7. **Accessibility audit:** Verify WCAG 2.1 compliance
8. **Performance testing:** Ensure <2s load times for typical data

---

## Architecture Compliance

All implementations follow StellaOps standards:

- ✅ **Deterministic:** Stable ordering, UTC timestamps, immutable data
- ✅ **Offline-first:** Minimal external dependencies, local caching
- ✅ **Type-safe:** Full TypeScript/C# typing with strict mode
- ✅ **Accessible:** ARIA labels, semantic HTML, keyboard navigation
- ✅ **Performant:** OnPush change detection, signals, lazy loading
- ✅ **Testable:** Unit test structure in place, mockable services
- ✅ **AGPL-3.0:** Open source license compliance
- ✅ **Air-gap ready:** Self-contained builds, no CDN dependencies
