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 pre-existing steam engine and identifiable Watt improvements must be documented, while the boundary of the word inventor is defined | input_limited | |
| H_VIDEO | positive_prediction | Newcomen-era engine records and Watt's 1765 condenser and 1769 patent would be observed | input_limited | |
| H_VIDEO | disconfirmer | A primary record showing Watt originated the first workable steam engine would disconfirm the strict only-improver formulation | input_limited | |
| H_VIDEO | alternative_mechanism | Legal invention of an improvement; popular attribution; multiple inventors across the engine lineage | input_limited | |
| H_VIDEO | formation_chain | Prior engine -> Watt condenser -> patent -> Boulton and Watt industrial implementation | input_limited | |
| H_VIDEO | fabrication_or_coordination_scope | not_required_by_claim_logic | not_applicable_by_claim_logic | |
| H_MAINSTREAM | necessary_condition | “改良者”须保留前瓦特蒸汽机、瓦特的增量设计及专利日期；“发明者”只能是语境性标签 | input_limited | |
| H_MAINSTREAM | positive_prediction | 会找到 Newcomen 等先例、瓦特分离冷凝器/效率改进和专利记录 | input_limited | |
| H_MAINSTREAM | disconfirmer | 若瓦特的关键装置无前例且记录显示其首创整个蒸汽机类别，改良者框架不足 | input_limited | |
| H_MAINSTREAM | alternative_mechanism | 把实用化/商业成功称为发明；把某一部件发明扩展为整机发明 | input_limited | |
| H_MAINSTREAM | formation_chain | 前人蒸汽机→瓦特观察/实验→分离冷凝器等改进→专利/应用 | input_limited | |
| H_MAINSTREAM | fabrication_or_coordination_scope | not_required_by_claim_logic | not_applicable_by_claim_logic |
