A decision on the flood map should be judged by what happens at the lower archive’s map room. 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.
63 marked waterways compared with the modern survey were entered this cycle, compared with 63 in the prior file. That comparison matters because the public summary counts entries. The open question is whether the old route is evidence of a lost spill channel or simply a copyist’s correction mark.
The mapmaker’s notes were added decades later; the archive has not found a matching field survey. 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.
Ava Korr checked the sealed flood map, the copy register and the mapmaker’s loose notes against the field notes. The method is to note who made a record, who preserved it and who can still consult it; it confirms the entries, but not every interpretation attached to them. The practical evidence is a faded blue line that bends around a sealed door absent from the modern map; 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. The archive will publish a high-resolution copy with each later mark dated separately. That is the narrowest decision that can be defended from the evidence now available.
