buildrun gains AssignerHolder, AssignmentsOf and SleepFor (moved from the builder's program, which uses them), so the builder and the checker follow the holder's first-view tool, views family and state alike; the checker's manifest consumes the seat's views assignments and reads its assignments state, its composition reads the picture once followed. The assigner's callers list for the first view gains the checker. Builds: design 47 G A-82, A-119, A-126, A-131 Claude-Session: https://claude.ai/code/session_01NcbgfGKaxw984XyAPfLm4h
