The first file on the surface mail tunnel began with sealed mail lists, transfer marks and the ridge carrier book. The city then checked the source, heard affected residents and sent a second office to repeat the count.
The current Year first, deep rest window 3 file records 71 sealed packets with a mark at both route transfers; the previous window records 74. The longer sequence makes the change visible, while each count remains tied to its own dates.
A turning point was the observation that the packet list is copied before the ridge carrier accepts the seal. It narrowed the discussion from a general claim to a question about how the rule works at the site.
The tunnel office counts a packet at dispatch. The ridge office counts it after the seal is checked. The shared record is larger than it was at the start, although the parties still assign it different weight.
Residents and route crews submit corrections before the public table closes. The Year first, deep rest window 3 file remains open for its scheduled decision. The next list will carry one seal mark from entry through final handoff.
