How this number is computed
Composite = sum of sub_score × weight across six metrics. Sub-scores are percentile-rank(log1p(min(raw, p95))) within the Update/Supported cohort (52 releases). Sub-scores for lower-is-better metrics are flipped to 100 − percentile.
| Sub-score | Formula | Raw | Clip | %ile | Weight | Score | Contrib |
|---|---|---|---|---|---|---|---|
| Breaking surface | (breaking_change + api_change) / total_notes | 0 | 0 | 33 | 25% | 67 | 16.8 |

* = raw value was clipped at the cohort 95th percentile to prevent outliers from compressing everyone else's scores. Sub-scores marked "med" substitute the cohort median where the input was missing (e.g. first patch on a minor line has no prior patch for net-fix delta).
