cohort: Update/Supported (62)

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 (62 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	31	25%	69	17.1
Blocker rate	blockers / total_notes	0.133	0.133	72	15%	28	4.2
Mobile risk	mobile_known_issues / total_notes	0	0	22	10%	78	7.8
Fix density	fixes / total_notes	0.600	0.600	38	15%	38	5.7
Net-fix delta	((fixes − known_issues) − prior.(fixes − known_issues)) / total_notes	-66.73	-66.73	0	15%	0	0.0

* = 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).
