Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Meta/facebook migrated metro packages to GitHub Actions CI publishing; SLSA attestation confirms legitimate CI origin. ai
publish-pattern dormant-publish AI (publish-pattern): Dormancy reflects upstream release cadence for facebook/metro, not account takeover; SLSA attestation confirms integrity. ai
phantom-deps phantom-dep:flow-enums-runtime AI (phantom-deps): flow-enums-runtime is a runtime dep used by Flow-typed code at runtime, not directly imported in JS; stable false positive for this package. ai
