Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Legitimate migration to GitHub Actions CI/CD publishing with SLSA provenance for cssnano monorepo. ai
publish-pattern dormant-publish AI (publish-pattern): cssnano monorepo resumed publishing via CI/CD; dormancy reflects normal maintenance cadence. ai
dependencies unvetted-dep:postcss-merge-idents AI (dependencies): postcss-merge-idents is a cssnano monorepo package; unvetted status is a pipeline lag, not a security concern. ai
dependencies unvetted-dep:postcss-reduce-idents AI (dependencies): postcss-reduce-idents is a cssnano monorepo package; unvetted status is a pipeline lag, not a security concern. ai
bogus-package bogus-package AI (bogus-package): cssnano monorepo releases explain all signals: mass-production publisher is expected, inflated semver tracks monorepo versioning, no keywords is common for ecosystem sub-packages. ai
phantom-deps phantom-dep:browserslist AI (phantom-deps): browserslist is legitimately declared for autoprefixer config passthrough; not directly imported by design. ai
dependencies unvetted-dep:postcss-discard-unused AI (dependencies): postcss-discard-unused is a cssnano monorepo package; unvetted status is a pipeline lag, not a security concern. ai
dependencies unvetted-dep:postcss-zindex AI (dependencies): postcss-zindex is a cssnano monorepo package; unvetted status is a pipeline lag, not a security concern. ai
