Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance no-provenance AI (provenance): async-lock is a well-established package (4100+ days old, 6.6M weekly downloads) from a known publisher; lack of Sigstore provenance is expected for packages of this age. ai
install-scripts install-script:postinstall AI (install-scripts): Postinstall script is an empty string (no-op); no code is executed. Stable false positive for this package. ai
