# Provenance repair coverage

**Claim grade:** C0-structural
**Audience:** Technical readers inspecting structural repair and stream-coverage evidence.

## Primary metric

- **Citation-spine stream coverage:** 99.3666 percent of reviewed streams
- Numerator / denominator: 254939 / 256564
- Estimator: Exact boolean coverage ratio in the reviewed stream-capability table.
- Uncertainty: Structural coverage is not a precision, recall, or publication-readiness claim.

## Supporting metrics

- **Poisoned-stream share:** 0.0795 percent of reviewed streams
- **Reviewed repair rows per gap product:** 24093465.5000 rows per repair product

## Accessibility fallback

The reviewed capability table marks 254939 of 256564 streams as citation-spine covered.

## Caveats

- This card reports structural custody and coverage, not empirical citation correctness.
- The three repair products retain distinct grains and should not be unioned as observations.
