Discard an assignment set
Calls a composition off and RELEASES its receivables back to the assignable pool. Allowed from every state except accepted, whose receivables were sold and written off, and refused for any composition that already sold part of itself: a line already accepted and written off, or a title already moved to the fund at the registry. Nothing is deleted: the set rests in the terminal cancelled state with its items, its transitions, its approval and its custodied signature evidence intact, and one append-only audit row names who called it off and why. Discarding a set that is already cancelled is inert.

Body
Why the composition was called off. abandoned: nobody is going to finish it. member_ineligible: a line in it can never be sold and was holding every other line with it. counterparty_declined: the fund or its administrator walked away outside the remessa. superseded: replaced by another composition. Required — free text is a disposition nobody can count.
abandoned, member_ineligible, counterparty_declined, superseded The particulars, in the operator's own words. Optional; omitted rather than blanked on the audit row when there is nothing to add.

OK
Where the set stood when the decision landed, or the state it was already in on a replay.
True when this set was ALREADY discarded and nothing was written. No second audit row was appended and no second decision was recorded.
The composition that was called off.
Always cancelled: the terminal state a discarded composition rests in. Nothing is deleted — the items, the transitions, the approval and the custodied evidence all stand.
