Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Publisher changed to GitHub Actions with SLSA provenance; this is a CI/CD migration, not a takeover. ai
phantom-deps phantom-dep:domain-objects AI (phantom-deps): Declared but not directly imported; likely used in config/type definitions only. ai
install-scripts install-script:postinstall AI (install-scripts): Husky git-hooks guard; only executes in git repos (dev environments), harmless for downstream consumers. ai
