Start with bench reservations, tool handoffs and the repair board. It is the source used to decide how work can stay on schedule when a shared tool cannot be used at both benches at once; it is not the decision itself. The rule only works if the source describes conditions at the shared bench room near Copper Bend.

Known: the current file counts 24 reserved hours completed without a tool conflict, compared with 21 in the prior window. Afield walk checks the route from entry point to final branch. The entries have dates and a named clerk.

Disputed: The reservation book allocates benches. Workers ask that shared tools appear in the same schedule. One side emphasizes the posted total; the other points to two adjacent benches share one clamp during the second shift.

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 second, vent change window 1 file remains open for its scheduled decision. The room will test a combined bench and tool reservation card.
