Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
email-domain unclaimed-email:stdarg.com AI (email-domain): Package is 4500+ days old with a clean publisher history (33/0). Domain lapse is a theoretical risk but no other compromise indicators exist across any version. ai
provenance no-provenance AI (provenance): Mature package predating Sigstore provenance; no CI/CD provenance is expected for packages of this age and publishing pattern. ai
