⚑ Top gap

Unstyled by design, so there is almost no token layer for Lyse to read.

Also flagged

→Theming and modes are left to the consumer — nothing to score.
→Agent-readiness is low: behavior is documented, tokens are not.

The verdict

Accessibility is close to best-in-class and the component contracts are exemplary. But Radix is primitives, not a full system — the missing token and theming layers are the point, and they also cap the score. An agent learns how it behaves, never what it should look like.
