/// ─────────────────────────────────────────────────────────────────────────
/// HOME IS TODAY, AND TODAY IS THREE TRIPS
///
/// Two bugs with one cause, and this is the file that holds the cause down.
///
/// ── What the rider saw ──
///
///  1. **Yesterday's assignments were on Home.** `GET /miler/bookings` returns
///     his whole *open* set, not his day, so a booking raised on Tuesday and
///     never closed came back on Wednesday and on Thursday — inside the kitchen
///     dropdown, and inside every count above it.
///  2. **Every run was Trip 1.** The hub assigns morning, afternoon and evening
///     slots and the tabs are those slots, but an evening run opened filed
///     under the morning.
///
/// ── The one cause ──
///
/// `ApiConfig.pickupFromBooking` builds a **fixed map**: a field it does not
/// name is a field no screen can ever see. Every timestamp on the booking was
/// unnamed, so it was thrown away at the adapter — and both features downstream
/// are clocks. [ServiceDay] asked "which day is this" in field names the
/// adapted row no longer spoke and got `''`; [Trip] asked "which part of the
/// day" and got the same silence, dropped every stop into one undated bucket,
/// and that bucket landed in the first free slot.
///
/// So the fix is at the adapter, and these tests start there. The two features
/// are then checked on the shapes the wire really produces.
/// ─────────────────────────────────────────────────────────────────────────

  /// A booking as `GET /miler/bookings` returns it — the new shape, which is
  /// the one that goes through the translation.
