On a mesh that predates the record, every handover has to begin by writing down who already holds the seat — otherwise the next holder cannot be assigned beside it, because two eligible claimants with nothing on record are refused. Found on the live mesh minutes after 0040 moved the bus seat's row: the standing holder no longer satisfies what the seat delivers, on purpose, and so could not be recorded, and so nothing could stand beside it. Recording who already holds is not making a new holder. Derivation never read what the seat delivers, so the standing holder holds regardless; when nothing is on record and the named assignment claims the seat at its scope, only that claim is checked. Every change of holder is still judged in full.
