Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
semgrep semgrep:dynamic-require AI (semgrep): Dynamic require() loads package.json files from paths resolved by find-root — core functionality of this duplicate-detection plugin. No arbitrary module loading risk. ai
provenance no-provenance AI (provenance): Package is 8+ years old, predating Sigstore provenance. Legitimate well-known webpack plugin with matching GitHub repo. ai
