The first bell foundry notice began with the casting ledger and the pitch checks from the west gallery. Since then, the city has moved through a source check, a public hearing and a trial at the bell foundry above the old ceremonial stair.
The current docket records 17 bells that held their assigned note after cooling; the earlier file recorded 19. The count is more specific than the first summary, but still does not answer whether the foundry can cast a new public bell without losing the pitch used for flood warnings.
A key point in the timeline was the discovery of a soft beat at the rim that appears only after the second cooling. It narrowed the dispute from a general claim about the rule to a question about how the rule behaves at the site.
The master caster says the alloy change is harmless; the signal crew says a narrow pitch shift can confuse a warning heard through stone. 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.
A public vote has approved a narrow change while leaving the larger question open. The entry belongs to the field review file at the bell foundry above the old ceremonial stair. The next casting will be tested from three listening posts before installation. The next review will show whether the change lasts beyond this docket or returns as another temporary exception.
