/// ─────────────────────────────────────────────────────────────────────────
/// THE RAIL COUNTS THE ROUTE, NOT THE RECORD
///
/// ── What the rider saw ──
///
/// He accepted one order out of five, picked it up, and the progress rail at
/// the top of Deliveries drew **five nodes**. One of them was his.
///
/// ── Where the other four came from ──
///
/// The rail reads the completed store, and that store is not a list of
/// finished deliveries. It is where every order that leaves the rider's hands
/// is filed, whatever ended it — and Home files a **declined** stop there too,
/// with `terminalStatus: 'rejected'`, so the decision survives on Activity.
/// That was harmless for as long as nothing read the store as a route. The rail
/// reads it as a route.
///
/// The count was the visible half. The colours were worse, and this is what
/// these tests really pin:
///
///   `rejected`   → [StopProgress.pending] — four stops he had **refused**,
///                  drawn on the rail ahead of him as work still to come.
///   `cancelled`  → [StopStatusX.isWorkComplete] → [StopProgress.done] —
///                  drawn **green**, claiming a delivery that never happened.
///
/// A skip is the case that must survive the fix: it is a door he went to and
/// could not finish, the rail has an amber node for precisely that, and losing
/// it would hide work he still owes.
