STATUS: The responsible office has offered a limited remedy with an end date for review. The current rule remains in force at the East Seam, four galleries below the old cart rail.
RECORD: The soundings book and the crew’s pre-entry inspection cards. This file counts 56 soundings recorded before entry; the prior count was 56.
DISPUTE: The foreman calls the readings a useful warning; the survey office says the marks need a second instrument before they can justify a closure.
WHY IT MATTERS: The decision concerns whether the new iron markers reveal movement early enough to keep crews out of a failing face. The current count does not settle how the rule should allocate the cost.
NEXT: A second surveyor will repeat the readings from the opposite wall. The clerk has marked the file EAST-SEAM-10 for the next public review.
