Asserts the assigned_resource edge (closing the rider’s previous unit, if any) and puts “{unit} assigned · {rider} · {guest}” on the Heartbeat. A unit is held by one open booking per departure window: 409 {reason: unit_busy, booking_ref} names the holder. A unit that is not active is 409 unit_unavailable. The same unit again for the same rider is 200 {already: true}.
