The first file on the fresh air regulator began with fan settings, air readings and the branch occupancy map. The city then checked the source, heard affected residents and sent a second office to repeat the count.
The current Year first, store season window 3 file records 40 readings with a fan setting and occupied branch attached; the previous window records 35. The longer sequence makes the change visible, while each count remains tied to its own dates.
A turning point was the observation that the fan is lowered during a stone inspection near one return shaft. It narrowed the discussion from a general claim to a question about how the rule works at the site.
The maintenance office posts a single average. Residents ask for the reading at the occupied branch during the change. 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 first, store season window 3 file remains open for its scheduled decision. The fan board will pair each reading with its setting and branch name.
