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 beta cohort (79 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	0.115	0.115	80	25%	20	4.9
Blocker rate	blockers / total_notes	2.5e-3	2.5e-3	41	15%	59	8.8

Fix density	fixes / total_notes	0.694	0.694	42	15%	42	6.4
Net-fix delta	((fixes − known_issues) − prior.(fixes − known_issues)) / total_notes	0.127*	0.114	96	15%	96	14.4
Known-issue debt	known_issues / total_notes	4.9e-3	4.9e-3	11	20%	89	17.8
Composite							62

* = 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).
