A decision on the east seam should be judged by what happens at the East Seam, four galleries below the old cart rail. The docket is at step 9 of the current review. Its latest entry reads: The first implementation notes have been compared with the promise in the minutes. A rule that looks complete in the chamber can still leave the people who use it carrying an unmeasured cost.
23 soundings recorded before entry were entered this cycle, compared with 24 in the prior file. That comparison matters because the public summary counts entries. The open question is whether the new iron markers reveal movement early enough to keep crews out of a failing face.
The foreman calls the readings a useful warning; the survey office says the marks need a second instrument before they can justify a closure. 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.
Dara Vek checked the soundings book and the crew’s pre-entry inspection cards against the field notes. The method is to start at the shift handoff, where an official total can lose its context; it confirms the entries, but not every interpretation attached to them. The practical evidence is a hairline change in the slate above the second timber brace; 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 second surveyor will repeat the readings from the opposite wall. That is the narrowest decision that can be defended from the evidence now available.
