Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Transition from primer-css to GitHub Actions is consistent with CI/CD automation; SLSA attestation confirms legitimate pipeline publish. ai
typosquat typosquat.levenshtein:yup AI (typosquat): Scoped @primer/mcp package from GitHub's Primer org; Levenshtein match to 'yup' is coincidental and not a typosquat. ai
phantom-deps phantom-dep:@babel/runtime AI (phantom-deps): @babel/runtime is a runtime peer of @babel/plugin-transform-runtime; conventional indirect usage, not a phantom dep concern. ai
