Start with the gate release board and millers’ water receipts. It is the source used to decide how water turns are apportioned when the clock and the gate marker disagree; it is not the decision itself. The rule only works if the source describes conditions at the South Canal sluice house.
Known: the current file counts 29 release minutes recorded at the lower gate, compared with 23 in the prior window. The council records a decision for this window and gives its written reason. The entries have dates and a named clerk.
Disputed: Millers use the gate clock to plan a shift. Canal crews compare it with the marked level on the stone wall. One side emphasizes the posted total; the other points to the downstream clock runs slow when its iron casing is cold.
Why it matters: the decision determines which residents can rely on the service and which staff must carry out the change. The file does not settle that by itself.
Next: The board recorded the outcome that it adopted an adjusted schedule for the next service window.
