## Affects

Teams that operate Lender receivables assignments.

## What changed

The guide now covers `POST /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.

## Impact

**Classification: Review recommended.**

## What you need to do

Review assignment runbooks and terminal-state handling before adopting the discard flow.

### Deadline

Before the next assignment-set cancellation.
