The first lantern fault notice began with the fault map, lamp checks and a sealed bag of recovered stone chips. Since then, the city has moved through a source check, a public hearing and a trial at the Lantern Fault below the east water gallery.
The current docket records 44 lamp readings taken at the marked stations; the earlier file recorded 47. The count is more specific than the first summary, but still does not answer whether a new side passage can be surveyed without drawing the east crew into an unmeasured seam.
A key point in the timeline was the discovery of a warm draft that changes direction just beyond the fourth marker. It narrowed the dispute from a general claim about the rule to a question about how the rule behaves at the site.
The draft suggests an open connection, but the old map records a collapse in the same direction. The current record does not settle that disagreement. The parties now share more of the record than they did at the start, though they assign it different weight.
Residents and workers have had their first chance to question the measure in public. The entry belongs to the renewal hearing file at the Lantern Fault below the east water gallery. The crew will hold the face while a remote lamp is lowered beyond the fourth marker. The next review will show whether the change lasts beyond this docket or returns as another temporary exception.
