Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance no-provenance AI (provenance): pngjs predates Sigstore provenance; publisher is the original author with long history. Stable FP for this package. ai
provenance missing-githead AI (provenance): gitHead omission reflects newer npm CLI behavior, not a security concern for this established package/author. ai
