removeDisbursementScheduleItemDocument

Mutation

Detach one document from a disbursement.

Only the reference is removed — the File record itself is retained, since it may be referenced elsewhere and the audit trail should still resolve it.

Rejected once the payment has settled — paid, an equivalent WoW terminal status, or completed — at which point the document list is frozen for every role. A refused payment is not a lock state: it is remediated and re-requested.

Returns RemoveDisbursementScheduleItemDocumentPayload !.
