Release 1.0.0-alpha10 Adds Wilson confidence interval and Cochran sample-size math to scoring/reporting, fixes three optimizer review findings (aggregated baseline gate, propose-margin ordering, bounded LLM judge input), exposes five previously config-only settings in the admin form, and rewrites the Cochran sample-size warning for clarity (now fires on any below-floor dataset, with plain-language framing and concrete actions). Supersedes the unpublished alpha9 tag.
