/**
 * Auth/authorization gaps (matrix Suite J), via route guard metadata — no boot needed.
 *
 *   C-8 🔴 The exchange-rate write routes (PUT upsert, PATCH update) carry no METHOD-LEVEL guard, so
 *          they get only the global JwtGuard (authentication) and NOT @PassengerAdmin (authorization)
 *          — unlike DELETE, which is admin-gated. Net effect (verified live in
 *          e2e-ui .../pb-config-propagation.spec.ts BC-11): anonymous → 401, but ANY authenticated
 *          user incl. a passenger → 200 rewrites live FX. fare-engine/currency.controller.ts:25,32,42
 *
 * NOTE: this metadata check proves the missing ADMIN guard, NOT "unauthenticated" — a global
 * APP_GUARD=JwtGuard (SharedAuthModule) still requires a valid token. The earlier "unauthenticated
 * FX write" reading was a false positive corrected by the live BC-11 test.
