A decision on the north sluice should be judged by what happens at the North Sluice above the Lantern Stair. The docket is at step 3 of the current review. Its latest entry reads: A field check has compared the written rule with the place where it is used. A rule that looks complete in the chamber can still leave the people who use it carrying an unmeasured cost.
27 measured release turns were entered this cycle, compared with 24 in the prior file. That comparison matters because the public summary counts entries. The open question is how much reserve water reaches the lower wards after a thaw pushes grit through the upper channel.
Keepers point to a steady total at the gate; residents point to a sharper fall in the last two cisterns. The current record does not settle that disagreement. The objection deserves a direct answer, but it is not a reason to make the rule permanent before the affected residents can check the method.
Tavi Orr checked the gate’s release board and the ward cistern level marks against the field notes. The method is to trace a system from its control gate to the last household it is meant to serve; it confirms the entries, but not every interpretation attached to them. The practical evidence is a stone channel that narrows at the final bend above the lower cisterns; any new measure should record that condition beside the total.
The chamber should approve a limited trial with a published end date, a way to record exceptions and a named reviewer. A mason crew will inspect the final bend during the next low-flow window. That is the narrowest decision that can be defended from the evidence now available.
