/**
 * Field-level guards for the durable application command mailbox (WFT-84).
 *
 * The generic checks — identities, durable JSON metadata, clock readings,
 * generated identifiers, derived instants, wait budgets — live in
 * `application-primitive-guards.ts` and are bound here to the mailbox's own
 * validation error class, so a mailbox caller always sees
 * `ApplicationCommandValidationError`. What remains here is what only the
 * mailbox validates: its backlog and listing ceilings, a claimant's rejection,
 * and a cancellation reason.
 *
 * Everything here is re-exported from `mailbox-validation.ts`, so
 * mailbox callers keep one import path.
 *
 * @module core/mailbox-guards
