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 referent steam engine must be fixed and the attribution must be separated from pre-existing Newcomen engines and Watt improvements | input_limited | |
| H_VIDEO | positive_prediction | Contemporary or institutional records would use inventor language for Watt while also identifying the prior engine lineage | input_limited | |
| H_VIDEO | disconfirmer | Prior-engine records and a patent framed around a separate condenser disconfirm the unqualified whole-engine reading | input_limited | |
| H_VIDEO | alternative_mechanism | Popular shorthand; legal patent attribution; attribution of a major improvement rather than the first engine | input_limited | |
| H_VIDEO | formation_chain | Prior steam engines -> Watt separate-condenser work -> patent and later implementation | input_limited | |
| H_VIDEO | fabrication_or_coordination_scope | not_required_by_claim_logic | not_applicable_by_claim_logic | |
| H_MAINSTREAM | necessary_condition | 蒸汽动力在瓦特前已有先驱装置；“发明蒸汽机”必须区分动力原理、可用机型与瓦特改进 | input_limited | |
| H_MAINSTREAM | positive_prediction | Savery/Newcomen 等前瓦特装置有独立日期和对象记录；瓦特专利/图纸显示具体改进 | input_limited | |
| H_MAINSTREAM | disconfirmer | 若不存在任何前瓦特蒸汽机，或瓦特记录明确承认创造首个蒸汽机原理，主流叙述需改写 | input_limited | |
| H_MAINSTREAM | alternative_mechanism | 发明/改良定义差异；后世品牌化归因；瓦特改进使旧原理商业化 | input_limited | |
| H_MAINSTREAM | formation_chain | 早期蒸汽装置→瓦特接触/改进→专利与商业化→后世“发明者”标签 | input_limited | |
| H_MAINSTREAM | fabrication_or_coordination_scope | not_required_by_claim_logic | not_applicable_by_claim_logic |
