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 (324 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 | 17.4 |
| Blocker rate | blockers / total_notes | 0.053 | 0.053 | 62 | 15% | 38 | 5.7 |
| Mobile risk | mobile_known_issues / total_notes | 0 | 0 | 15 | 10% | 85 | 8.5 |
| Fix density | fixes / total_notes | 0.772 | 0.772 | 90 | 15% | 90 | 13.4 |
| Net-fix delta | ((fixes − known_issues) − prior.(fixes − known_issues)) / total_notes | 0.035 | 0.035 | 52 | 15% | 52 | 7.8 |

* = 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).
