双轨条件矩阵
H_VIDEO 与 H_MAIN 独立列出必要条件、正向预测、反证条件、替代机制、形成链和协调伪造规模。
| 模型 | 条件类型 | 条件 | 评估 | 关联证据 |
|---|---|---|---|---|
| H_VIDEO | necessary_condition | The related apparatus must be uniquely identified and a dated first-contact record must establish that no earlier European analogue or independent form existed | input_limited | |
| H_VIDEO | positive_prediction | A 13th-century record would explicitly describe first sighting or first import of the same apparatus and earlier records would be excluded | input_limited | |
| H_VIDEO | disconfirmer | A dated European water-bellows or piston apparatus before or around the claimed window disconfirms the universal first-contact timing; device mismatch limits scope | input_limited | |
| H_VIDEO | alternative_mechanism | First contact with a particular Chinese variant; independent local development; retrospective “first” meaning | input_limited | |
| H_VIDEO | formation_chain | Chinese apparatus -> named intermediary -> European first sighting -> reaction or adoption | input_limited | |
| H_VIDEO | fabrication_or_coordination_scope | not_required_by_claim_logic | not_applicable_by_claim_logic | |
| H_MAINSTREAM | necessary_condition | “欧洲13世纪首次见到”须指明装置、欧洲观察者、日期、接触地点和传播路线；首次断言需先定义范围 | input_limited | |
| H_MAINSTREAM | positive_prediction | 会有13世纪欧洲记录或更早/同期欧洲本地鼓风设备记录，且能区分中国来源 | input_limited | |
| H_MAINSTREAM | disconfirmer | 出现更早可识别接触、欧洲本地同类，或没有可定位的13世纪接触记录会削弱该断言 | input_limited | |
| H_MAINSTREAM | alternative_mechanism | 首次见到的是普通风箱而非水排；欧洲独立发展；时间或 ASR 误听 | input_limited | |
| H_MAINSTREAM | formation_chain | 中国对象→跨区域接触→欧洲记录→术语对应→首次日期比较 | input_limited | |
| H_MAINSTREAM | fabrication_or_coordination_scope | not_required_by_claim_logic | not_applicable_by_claim_logic |
