A row that carries its submission body is resumed whatever the caller's scope
digest (the world answers it by command id); a row still in flight keeps the
digest gate. World and scope must always match. GroupedRun.refused names each
constituent that did not commit (LeftBeforeSelection, ScopeChanged,
WorldRefused); needs keeps decode problems only. A group submits declines
first, then exercises in the world's attention order read once.
Not verified at this commit (written before the first build).
