Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
publish-pattern dormant-publish AI (publish-pattern): MetaMask core monorepo; release cadence gaps are normal for this package family. ai
maintainer-change maintainer-removed AI (maintainer-change): MetaMask org manages maintainers centrally via metamaskbot; individual removal is routine org hygiene. ai
provenance no-provenance AI (provenance): MetaMask monorepo packages consistently publish without Sigstore provenance; not a risk signal for this publisher. ai
phantom-deps phantom-dep:@open-rpc/meta-schema AI (phantom-deps): Declared as runtime dep and used in config/schema validation; phantom-dep heuristic false positive for this package. ai
