Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance missing-githead AI (provenance): Established package from trusted publisher zkochan; missing gitHead reflects a publish environment change, not a supply chain compromise. No other risk signals present. ai
provenance no-provenance AI (provenance): Package predates Sigstore provenance adoption; trusted publisher with 99 approved packages and clean history. Absence of attestation is not a risk for this package. ai
