SAME: a payment carries the same sign as what it settles, so a negative amount is a reversal. OPPOSITE: a payment carries the opposite sign of the invoice it settles. In 1:N contexts only payments of the declared sign are allocated to an invoice, and in N:M contexts a short-paid invoice keeps an open balance only when it is positive under SAME, or when the rule's sign mode is opposite under OPPOSITE; any other short payment stays unmatched; a carried open balance settles on a payment of the declared sign or on a reversal from the invoice's own side, and a row from an archived source stays unmatched. It cannot change once the context has carried a partial balance, or while a match run is in progress. enum: - SAME - OPPOSITE examples: - SAME type: string status: description: >- Lifecycle status.
