A decision on the shared cistern levels should be judged at the cistern at Lantern Well, where the rule changes an ordinary route, shift or service. Trace each route from its entrance marker to the last branch that residents rely on. The current file is the Year fourth, vent change window 1 review, not a permanent settlement of every future case.
The the draw board and readings kept by three connected rooms lists 37 draw turns recorded at each branch connection; the previous window lists 39. Kip Copper checked both against check-out slips compared with the handoff mark at the next station. The difference matters because how a shared cistern turn is measured at the branch that fills last.
The cistern keeper counts one release. The far branch residents say their turn begins after the near room has closed its valve. Those objections deserve a clear answer. They are not a reason to keep an uncheckable rule simply because its wording is familiar.
A useful decision names who will do the work, which count will change and when the result comes back to the public table. In this case, the nearest room fills before the far branch opens.
The Year fourth, vent change window 1 file remains open for its scheduled decision. The draw board will show start and end marks at each branch valve.
