Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Vercel migrated publishing from vercel-release-bot to GitHub Actions CI; SLSA attestation confirms legitimate pipeline. ai
publish-pattern dormant-publish AI (publish-pattern): vercel-release-bot with strong track record; v2.0.0 major release explains gap. ai
maintainer-change maintainer-removed AI (maintainer-change): Vercel org manages maintainers centrally; removal consistent with team changes, not takeover. ai
publish-pattern new-deps-added AI (publish-pattern): md5 and semver are established, low-risk packages appropriate for config/validation tooling from a trusted Vercel publisher. ai
phantom-deps phantom-dep:@types/md5 AI (phantom-deps): @types/md5 is a type declaration for the md5 runtime dep; declared in dependencies for type resolution, stable false positive. ai
dependencies unvetted-dep:http-proxy AI (dependencies): http-proxy is a well-established package; its use here is consistent with the proxy functionality of this microfrontends library. ai

HIGH Publisher changed: vercel-release-bot → GitHub Actions (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.
