Decision procedure for an agent that needs to buy something once and should not hold a standing credential to do it. Ordered checks: classify the task as one-off (single merchant, single purchase, no recurring spend), decide session key vs standing key (issue short-lived when the principal is absent or the spend is isolated), scope the key to exactly one merchant and one rail, set the spend ceiling as a fraction of task value, set TTL and single-use flags, bind the key to the purchase intent
