// without inventing the dungeon-mission reward that its class-1 response must
// carry. Current EXE sub_1DBAE90 proves the success payload is
// missionSuccess=1 followed by a real item-template ID. The bridge has no
// active op558 mission instance or authoritative reward source yet, so it must
// expose the missing evidence rather than send a fake item ID or conflate this
// general dungeon side-mission ACK with room gates or return-town.
