Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Robin Malfait (malfaitrobin) is a known Tailwind CSS core team member; publisher transition from adamwathan is legitimate team handoff. ai
maintainer-change maintainer-removed AI (maintainer-change): Maintainer list changes reflect normal team reorganization within tailwindlabs. ai
publish-pattern dormant-publish AI (publish-pattern): Gap reflects Tailwind v3→v4 transition cycle; 789 versions in registry show active maintenance. ai
phantom-deps phantom-dep:tailwindcss AI (phantom-deps): tailwindcss is a first-party monorepo sibling listed as a dependency; it being referenced in config rather than directly imported is expected for this PostCSS plugin package. ai
