/**
 * Public API v1 — the versioned read-only surface for third-party integrations.
 *
 * Imports rather than re-implements: token verification comes from TokensModule,
 * trip access from TripMembershipModule and DatabaseService. This module owns the
 * payload shaping and nothing else, so there is no second place where "who may read
 * this trip" is decided.
 *
 * Deliberately a leaf. Pulling in a domain module for one table drags its whole
 * graph along: AtlasModule needs AuthModule, which boots the storage registry,
 * which reads app_settings on init. A read-only surface that cannot start without
 * half the application is one that breaks for reasons it has nothing to do with.
 *
 * That constraint is why `GET /api/v1/stats` is not declared here: its figures are
 * AtlasService's, so the route lives in `atlas/` instead and provides this guard
 * class itself. No module edge either way — which is the point.
