Terminate Schedule Early

End a schedule early at a month-end cutoff without booking any entry. In one transaction: deletes forward facts past the cutoff (refusing when posted entries exist past it; stale drafts past it are deleted), voids the remaining obligation chain past the cutoff (pending and classified rows), and rewrites the SumEquals rule to prove the truncated curve. History at or before the cutoff is untouched, so open months the schedule still covers close normally. Use this when the termination's GL effect is already booked (an asset transferred via a manual entry, a prepaid refunded in the source system) or none is wanted; when the derecognition entry still needs to be booked, use create-event-block(event_type='asset_disposed') instead — the disposal handler posts it atomically with the same obligation void. Run BEFORE promote-obligations at close so terminated periods are never drafted.
