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 | “火字旁”所指汉字须能从原音频或文本确定；该字须在历史语境中具有烧水产蒸汽的技术语义 | input_limited | |
| H_VIDEO | positive_prediction | 原始词形、字形和上下文可定位；同代技术语境支持该解释 | input_limited | |
| H_VIDEO | disconfirmer | 所指词语缺失；引文无法定位；字形只被事后拆字或谐音解释 | input_limited | |
| H_VIDEO | alternative_mechanism | 字源/象形修辞；ASR错词；现代蒸汽概念回投 | input_limited | |
| H_VIDEO | formation_chain | 音频词形→字形/出处→语义→动力解释 | input_limited | |
| H_VIDEO | fabrication_or_coordination_scope | none;音频核验是信息缺口而非协调假设 | input_limited | |
| H_MAINSTREAM | necessary_condition | the cited character/component must be philologically interpreted in its historical context; the video must make an explicit bridge from lexical component to physical apparatus; the apparatus claim needs independent evidence | input_limited | |
| H_MAINSTREAM | positive_prediction | technical text or diagram should use the word as a steam-power specification and separately identify a boiler/engine | input_limited | |
| H_MAINSTREAM | disconfirmer | lexicons can record heat/steam senses without encoding an engineering design; component meaning is not a causal mechanism; ASR or modern semantic projection may be wrong | input_limited | |
| H_MAINSTREAM | alternative_mechanism | phonetic component; dictionary indexing radical; mnemonic/pun; later meaning of steam not early ship technology | input_limited | |
| H_MAINSTREAM | formation_chain | FC-F5-C01 | input_limited | |
| H_MAINSTREAM | fabrication_or_coordination_scope | not_required_by_claim_logic | not_applicable_by_claim_logic |
