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 alpha cohort (43 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	0.065	0.065	52	25%	48	11.9
Blocker rate	blockers / total_notes	2.6e-3	2.6e-3	20	15%	80	12.0

* = 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).

Fixed a crash when a Tilemap Prefab whose Scene instance has tile overrides was updated outside the Editor. (UUM-157167) Fixed in 7000.0.0a12.
