/**
 * v1.38.12 — what a delegate is told they may do, and what the routes then do.
 *
 * `GET /api/auth/me` publishes two lists on the active entry,
 * `writableDomains` and `manageableDomains`, and every add / edit / delete
 * control in a shared record reads them. The lists are worth nothing unless
 * the routes agree with them, so this file drives both ends over the real
 * route handlers, the real grant table and real Postgres:
 *
 *   1. a guardian acting on a managed profile reads the payload and gets
 *      every section with a delegated route as manageable, and never the
 *      vault;
 *   2. the same guardian posts a mood entry and an allergy — the two writes
 *      #939 was reported on — and both land on the PROFILE's record;
 *   3. the same guardian is refused a vault write, which is what the empty
 *      answer for `documents` promised;
 *   4. a WRITE delegate on an adult's record reads writable sections and no
 *      manageable ones, and is refused the mood entry the list withheld.
 *
 * The lists are compared against `delegatedDomains`, the helper the resolver
 * itself runs, so a change to the table shows up here as a change in what the
 * routes must then honour, not as a fixture to update.
