A decision on the surface mail tunnel should be judged at the mail branch between Underway and Flint Ridge, where the rule changes an ordinary route, shift or service. Trace each route from its entrance marker to the last branch that residents rely on. The current file is the Year third, deep rest window 3 review, not a permanent settlement of every future case.
The sealed mail lists, transfer marks and the ridge carrier book lists 77 sealed packets with a mark at both route transfers; the previous window lists 78. Kip Copper checked both against check-out slips compared with the handoff mark at the next station. The difference matters because how a sender checks a packet that changes hands between the tunnel and ridge routes.
The tunnel office counts a packet at dispatch. The ridge office counts it after the seal is checked. Those objections deserve a clear answer. They are not a reason to keep an uncheckable rule simply because its wording is familiar.
A useful decision names who will do the work, which count will change and when the result comes back to the public table. In this case, the packet list is copied before the ridge carrier accepts the seal.
The board recorded the outcome that it sent a separate sign question to a new route review without reopening this one.
