The revision of the last whole-console commit; 0 when none this boot.
The console-wide revision — what every frame and body is stamped with.
The corrections row's state.
One committed write, whichever door — called from the registry's commit observer, the same listener that drives autosave and undo, so there is no second counter site to drift.
Stamp the barrier at the CURRENT revision — the landing of a whole-console operation. See observe for why an operation's fire must not stamp it.
Record one client's correction — the loud part. Returns the minted entry.
The heartbeat row's state, minus the console-owned config the server row composes in.
The counters and the log, pure and synchronous — the server registers the rows over it and calls observe from its one commit listener.
