**An acknowledgement is what the provider returns at once. HTTP 200 and a refund object are an acknowledgement. It is evidence level E1. It proves that the request was accepted. It never proves terminal success by default.**

Example: Stripe returns a refund object with `status: pending`. The object exists. The money has not moved. The agent that reports "refunded" here reports a false completion.
