Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| 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 |
