## 10. Requirement Traceability

### 10.1 Requirement IDs

Every functional requirement in section 5 uses a unique FR-xxx ID. These IDs serve as the primary traceability anchor across user stories, code, and tests.

| FR ID | Requirement | Priority | Stories | Status |
|-------|-------------|----------|---------|--------|
| FR-001 | {requirement} | P0/P1/P2 | US-{xxx} | Draft / Covered / Verified |

### 10.2 Coverage Summary

| Metric | Count | Percentage |
|--------|-------|------------|
| Total Requirements | {n} | 100% |
| Covered by Stories | {n} | {%} |
| Covered by Code | {n} | {%} |
| Covered by Tests | {n} | {%} |

> Run `/project:coverage-map` to generate an up-to-date coverage report.
> Run `/project:trace` to view the full bidirectional traceability matrix.
