Coordinated cancellation must expose the adjustment and money-return components together. ## Interactions Between Capabilities A billed reduction changes receipt availability, and coordinated cancellation adds fee and return treatment to that released value. Opposing adjustments preserve the records needed to explain restored debt. ## Regression Record Revision one establishes the initial cumulative suite. Later changes revisit dependent scenarios, and retired scenarios retain their identities and reasons.
