Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): yarnbot is the official Yarn Berry CI publisher; transition from arcanis is expected and backed by SLSA provenance. ai
maintainer-change maintainer-removed AI (maintainer-change): Yarn Berry consolidates publishing under yarnbot automation; maintainer list changes are expected org-wide. ai
publish-pattern dormant-publish AI (publish-pattern): 103 versions in registry; batch/coordinated release cadence explains apparent dormancy gaps. ai
dependencies unvetted-dep:@yarnpkg/plugin-pnp AI (dependencies): First-party @yarnpkg/* dependency within the same Yarn Berry monorepo; not a third-party risk. ai
npm-metadata no-description AI (npm-metadata): Official Yarn Berry plugin; missing description is a known pattern across the monorepo, not a risk indicator. ai
provenance no-provenance AI (provenance): Established Yarn Berry package; lack of provenance is consistent across the monorepo and not a risk signal here. ai

HIGH Publisher changed: arcanis → yarnbot (on 2026-05-19) provenance

This version was published by a different npm account than previous versions on 2026-05-19. This could indicate a legitimate maintainer transition or an account compromise.

INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.

v4.0.8

1 finding

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.

v4.0.7
