Every seat constant of mesh-sdk is mesh-contracts' generated name; the four whole seats' (BrokerSeat, CheckerSeat, asks.Seat, buscompose.VaultSeat) are marked deprecated for their importers. The package walk of mesh-sdk's own check refuses a string literal naming a defined seat or its subjects, and an exported name given to one, beyond testdata/seat-names.txt, which lists what stands before the move (module names that equal a seat's among them) and only shrinks. No new test function. Claude-Session: https://claude.ai/code/session_01JG73KJNrH5EgFXMKKYSrig
