version lets a later args shape fail loudly on a worker that predates it.
Version 2 links a B2C session first, so a failed start leaves nothing linked;
version 1 keeps its command sequence, so runs open at deploy replay.
Version 3 is an operator's org re-run; a worker that predates it fails the
start without retrying and writes nothing.
