Start with the booking slate, rehearsal requests and sound checks. It is the source used to decide how groups share the stage when a change in the room alters the sound check; it is not the decision itself. The rule only works if the source describes conditions at the public stage at Underway Hall.
Known: the current file counts 83 public nights with a rehearsal interval confirmed, compared with 83 in the prior window. The table records the result and the branches included in the decision. The entries have dates and a named clerk.
Disputed: The hall rotates public nights equally. Performers ask for the same rehearsal interval after a sound screen moves. One side emphasizes the posted total; the other points to a new sound screen changes the return heard from the last bench.
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 board recorded the outcome that it closed the file after both approaches matched the public map.
