"""Late settlement requires a real executing transition (R4 item 4).
An admitted status also describes pending, never-dispatched work, so the
async-completion seam must demand the executing marker and refuse
contradictory pending/executing state before persisting a late result.
Settling a stopped run twice is rejected; ownership stays enforced.
