### 3.2 Requirement coverage

Every SWE requirement is referenced by at least one unit test (via `@reqs` tag in the test file):

| SWE Req                | Test function(s)                                            |

SWE requirements of the not-implemented stub components (SWA-004..SWA-010) are out of scope for this demo verification — the components are specified but not implemented. In a real project they would all be verified.

### 3.3 Coverage metrics (demo components)
