Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance missing-githead AI (provenance): fp-ts is a mature, high-trust package from its original author gcanti. Missing gitHead reflects a publish-environment change, not a supply-chain risk. ai
provenance no-provenance AI (provenance): fp-ts predates Sigstore provenance; absence is expected for this package's publish workflow. ai
