Teams that operate Lender receivables assignments.What changed
The guide now coversPOST /api/v1/assignment/sets/{setId}/discard. It cancels an unsold assignment composition, returns its receivables to the assignable pool, and preserves the set, evidence, and audit trail. It does not undo a sale. Lender rejects it for accepted, partly sold, paid, or registry-lodged sets. This update documents the current operation; it does not announce a runtime release.
