The first file on the oral map index began with spoken route notes, carved markers and the public branch map. The city then checked the source, heard affected residents and sent a second office to repeat the count.
The current Year fifth, vent change window 3 file records 23 spoken names linked to a direction and junction; the previous window records 18. The longer sequence makes the change visible, while each count remains tied to its own dates.
A turning point was the observation that one route name describes the sound heard at a junction rather than its shape. It narrowed the discussion from a general claim to a question about how the rule works at the site.
The map room wants direction names. Residents use sound names to remember the route. The shared record is larger than it was at the start, although the parties still assign it different weight.
The clerk attaches the current passage map and the last change card. The Year fifth, vent change window 3 file remains open for its scheduled decision. The index will link the spoken name to the junction and branch arrows.
