Assertions

Area	Expected result

Waiting / failure	No settlement
Success	Actual completion_tokens and exact pricing variant
Repeated success queries	One event; five scope totals increment once
Missing rate	Preserve usage and unpriced; not free

Validate live supplier tasks for each model independently; local task tests do not establish supplier availability or invoice amounts. No background polling, budget reservation, create-time price locking, repricing entries or provider invoice reconciliation exists.
