视频把1770年送书与1771年改良解释为因果关系
判定边界
双方证据链未闭合（本轮），不是双方等真，也不是给视频主张背书。

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 | A causal bridge needs object access content match comprehension design adoption and output, not only two dates | input_limited | |
| H_VIDEO | positive_prediction | Correspondence or notes would connect the delivered book to a specific 1771 Watt change | input_limited | |
| H_VIDEO | disconfirmer | The available Watt chronology predates the proposed handover and no direct transfer chain was located; this is a broken bridge, not proof of impossibility | input_limited | |
| H_VIDEO | alternative_mechanism | Independent improvement; Newcomen lineage; later narrative compression | input_limited | |
| H_VIDEO | formation_chain | Book delivery -> reading and understanding -> design change -> dated 1771 output | input_limited | |
| H_VIDEO | fabrication_or_coordination_scope | not_required_by_claim_logic | not_applicable_by_claim_logic | |
| H_MAINSTREAM | necessary_condition | 因果成立须有书籍可达、瓦特实际接触、理解、设计变化和时间顺序；先后关系本身不足 | input_limited | |
| H_MAINSTREAM | positive_prediction | 若存在传教士/书籍链，瓦特记录应引用或显示新知识输入，并在设计上出现对应输出 | input_limited | |
| H_MAINSTREAM | disconfirmer | 瓦特在交书前已有关键设计，或无接触/理解/引用/输出证据，会削弱因果桥 | input_limited | |
| H_MAINSTREAM | alternative_mechanism | 独立工程迭代；多源欧洲知识；后见之明把相邻年份串成因果 | input_limited | |
| H_MAINSTREAM | formation_chain | 1770交付?→瓦特接触/理解?→设计变化?→1771改良?→可重复技术输出 | input_limited | |
