+ * Per-schedule wagon CUT plan — the mid-route stop where THIS departure
+ * detaches each consist wagon and leaves it behind (10 wagons cut at Mojo,
+ * the rest ride to Djibouti).
+ *
+ * Sparse jsonb map `{ wagonId: yardId }` on the schedule: a wagon missing
+ * from the map rides to the schedule destination — exactly today's behavior,
+ * so no backfill. The cut is a cap, not a promise: cargo may still alight
+ * earlier, but never past the cut. Booking capacity debits every edge at or
+ * after the cut; checkpoint logging settles the wagon there physically.
