# Test Coverage & V&V (Annex IV §1.6)

## Verification (Implementation Correctness)
- **570+ Jest Suites:** 100% coverage (npm test); Includes mocks for Playwright.
- **Key Suites:** sanitizer.test.ts (43/43 patterns); ThreatDetector.test.ts (19 IPI); immutable-ledger.test.ts (Merkle proofs).
- **Coverage Tool:** Jest --coverage → /coverage/lcov-report/index.html.

## Validation (Art. 15 Robustness)
- **Adversarial Testing:** injection-corpus.ts (real exploits); E2E in fetch-tool.test.ts.
- **Performance Benchmarks:** crypto-performance.test.ts (<500ms sanitizer); tokenMetrics.test.ts (70% reduction).
- **Cybersecurity Mapping (Art. 15):**
  - (a) Attacks: IPI/worm 100% detection.
  - (b) Vulnerabilities: npm audit zero; No secrets (env-only).
  - (c) Oversight: HITL logs verified.
  - (d) Updates: Quarterly (e.g., v0.18.0 worm patterns).

**Validation Results:** All suites PASS (0 failures); Meets Art. 15 via 100% adversarial coverage.
