SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Moved to GitHub Actions CI/CD publishing with SLSA provenance; legitimate automation transition. ai
publish-pattern dormant-publish AI (publish-pattern): Major version bump after dormancy is normal for mature utility packages. ai
source-diff source-size-tripled AI (source-diff): v5 adds Web Streams support and TypeScript types; size increase is expected. ai
