Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
publish-pattern new-deps-added AI (publish-pattern): The new dep 'ext' is authored by the same maintainer (medikoo) as es6-symbol, replacing es5-ext in a routine internal refactor. No supply-chain risk. ai
dependencies unvetted-dep:d AI (dependencies): Package `d` is a well-known utility by the same publisher (medikoo) with a long history; not a risk for this package. ai
dependencies unvetted-dep:ext AI (dependencies): Package `ext` is a well-known utility by the same publisher (medikoo) with a long history; not a risk for this package. ai
provenance no-provenance AI (provenance): Package is 12+ years old, predates Sigstore provenance. High download volume and trusted publisher make this a stable false positive for this package. ai
