/// ─────────────────────────────────────────────────────────────────────────
/// THE XPRESS SUBTREE IS A REFERENCE, NOT A DESTINATION
///
/// `lib/xpress` is a verbatim port of the Xpress-rider app, kept beside this
/// one so its proven delivery UX can be read while the Miler-native milk run is
/// built. It is **not** one of the two operations the hub runs, and the Milk Man
/// flow is implemented natively in Miler — Miler screens, Miler controllers,
/// Miler API layer — rather than by routing riders into it.
///
/// ── What this file used to assert, and why it changed ──
///
/// It used to prove the opposite: that a tenant *named* "delivery"/"xpress", or
/// an account in `configid: 6`, would land the rider in that other application.
/// That was reasonable while the tenant was unknowable — the build flag and a
/// name were the only signals there were.
///
/// It is not reasonable now. `verify-pin` returns a real `tenantname`, which
/// means an arbitrary string chosen by whoever set up a client in the admin
/// console reaches this resolver. A client called "Delivery" is an entirely
/// plausible thing to create, and under the old rule that alone would have
/// dropped a live rider into a different app with a different bottom bar, a
/// different set of endpoints and no shipment desk. The failure would look, to
/// him, like the app breaking.
///
/// So the wire cannot reach it any more. Only `--dart-define=TENANT=delivery`
/// can, and that is a compile-time constant no test can set — which is the
/// point. What is tested here is the closed door.
