Fragment delivery remains one bounded action per scope and replays both argument fragments through both production accumulation APIs; streaming cleanup remains attached to streaming finalization because late delivery is the only valid following local phase. This preserves each request's local order while keeping CI runtime bounded. The expected schedule count, maximum schedule budget, scope count, raw index, and actions per scope are explicit.
