SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Publisher changed from personal account to GitHub Actions CI/CD, consistent with adopting automated publishing. SLSA provenance attestation confirms build integrity. Stable pattern for this package going forward. ai
publish-pattern dormant-publish AI (publish-pattern): Dormancy is explained by the transition to GitHub Actions publishing pipeline. SLSA attestation and no material diff confirm legitimate activity. ai
