Case contract

Input {'fares':[[basis, amount, rbd, min AP days, 'OW'|'RT']],'trip','ap_days','rbd_open'}. A fare applies if its AP requirement <= ap_days and its booking class is open. OW trips use OW fares only; RT trips use an RT fare or two of the same OW fare. Pick the lowest total; ties prefer the booking class earlier in 'YBMHQVLKTN'. Return [[bases], total] or 'NO_FARE'.

Why this case matters

Fare shopping filters by rule applicability and inventory, compares round-trip fares against doubled one-way fares, and needs a deterministic tie rule.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
