The explicit "Search the library" box (BUG-3c escape hatch): the doctor typed a query on purpose, so this is more permissive than the auto-suggest — any token overlap matches, ranked by relevance. A blank query returns the library head so the box is never a dead end. skipped when the specialty has no library. Never gated on the independent commit (the doctor is grounding their OWN text, post-reveal), like /assist/cite.

TUTORIAL rather than full access (PRD A §2.1): an applicant sitting the credentialing examination has to be able to cite, and "Search the library" is the box they do it in. Nothing patient-specific is reachable through it — the library is published guidance, keyed by specialty — so it is a surface-level permission rather than a task-scoped carve-out. It admits advisors too, who already hold TUTORIAL and already click through the whole practice case; the same reasoning covers both.
