Response
Created quick check
A check printed by Arcus (paper AP payment).
Available options:
printed_check Sequential per bank account.
Available options:
printed, reprinted, voided, cleared The EVIDENCE CLASS behind status=cleared. register_only means the payment leg already credited a bank account and no journal entry was posted for the clear, so the row is a register truth and NOT a bank fact. Null on a check cleared before migration 20260915a, when nothing recorded the class.
Available options:
bank_match, manual_clear, register_only, migrated The bank line that paid this check. Written when the clear is driven by a matched bank row; null for a manual clear and for every check cleared before 2026-09-18. When it is null the pairing may still be recorded on the bank side.
