Start with the room booking ledger and light maintenance notes. It is the source used to decide how to keep the room usable during a repair without excluding evening learners; it is not the decision itself. The rule only works if the source describes conditions at the shared table at Starwell Study House.

Known: the current file counts 29 booked hours when the room is open and evenly lit, compared with 26 in the prior window. The steward attaches the original field record and the last method note. The entries have dates and a named clerk.

Disputed: The repair crew favors a full closure. Learners ask for the bright side of the room to stay available. One side emphasizes the posted total; the other points to one lamp circle remains dim after a new branch was routed through the ceiling.

Why it matters: the decision determines which residents can rely on the service and which staff must carry out the change. The file does not settle that by itself.

Next: The Year third, canopy height window 1 file remains open for its scheduled decision. The coordinator will trial a divided room plan until the branch repair is complete.
