The first file on the hill route agreement began with the route agreement, repair notices and the two public marker boards. The city then checked the source, heard affected residents and sent a second office to repeat the count.

The current Year second, vent change window 1 file records 28 repairs posted at both ends before a path closes; the previous window records 23. The longer sequence makes the change visible, while each count remains tied to its own dates.

A turning point was the observation that one notice board is inside the tunnel and the second faces the ridge. It narrowed the discussion from a general claim to a question about how the rule works at the site.

Each town posts promptly at its own end. Travelers need the same closure time on both boards. The shared record is larger than it was at the start, although the parties still assign it different weight.

Afield walk checks the route from entry point to final branch. The Year second, vent change window 1 file remains open for its scheduled decision. The route offices will share a dated notice before the next repair.
