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 (81 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	0.119	0.119	83	25%	17	4.2
Blocker rate	blockers / total_notes	2.8e-3	2.8e-3	48	15%	52	7.9
Mobile risk	mobile_known_issues / total_notes	4.7e-4	4.7e-4	27	10%	73	7.3
Fix density	fixes / total_notes	0.694	0.694	44	15%	44	6.6
Net-fix delta	((fixes − known_issues) − prior.(fixes − known_issues)) / total_notes	0.078	0.078	88	15%	88	13.2
Known-issue debt	known_issues / total_notes	0.012	0.012	71	20%	29	5.8
Composite							45

* = 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).
