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 LTS cohort (307 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 | 30 | 25% | 70 | 17.5 |
| Blocker rate | blockers / total_notes | 0.074 | 0.074 | 81 | 15% | 19 | 2.9 |

| Fix density | fixes / total_notes | 0.593 | 0.593 | 48 | 15% | 48 | 7.2 |
| Net-fix delta | ((fixes − known_issues) − prior.(fixes − known_issues)) / total_notes | 0.093 | 0.093 | 61 | 15% | 61 | 9.1 |

* = 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).
