Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance missing-githead AI (provenance): Long-standing package by original author; missing gitHead reflects a publish environment change, not a supply-chain concern. ai
provenance no-provenance AI (provenance): Informational finding; many established packages lack Sigstore provenance. Not a risk signal for this well-known package. ai
