# Requirements traceability matrix

<!-- GENERATED FILE — do not edit by hand. -->
<!-- Regenerate: cargo run -p traceability -- report -->

Denominators are parsed from [`requirements.md`](requirements.md) at run time, never hardcoded. Coverage is the intersection of tagged and defined IDs over defined IDs, so it cannot exceed 100%.

## Summary

| Metric | Value |
|---|---|
| Source files scanned | 129 |
| TRACES tags found | 278 |
| Requirements defined | 151 |
| Requirements covered | 82 |
| **Coverage** | **54.3%** (82/151) |

### By type

| Type | Covered | Defined |
|---|---|---|
| FR | 64 | 97 |
| NFR | 16 | 48 |
| R | 2 | 6 |

## Orphan tags

A tag naming an ID `requirements.md` does not define — what renumbering produces, and what a typo produces.

_None._
