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 | Population-level evidence must show widespread understanding or operation among Song ironworkers rather than a single design or elite description | input_limited | |
| H_VIDEO | positive_prediction | Workshop records manuals or multiple independent accounts would establish broad practical distribution and competence | input_limited | |
| H_VIDEO | disconfirmer | A technical illustration or isolated official description cannot establish all or most smiths understood it | input_limited | |
| H_VIDEO | alternative_mechanism | Specialized local experts; supervised operation; elite or state knowledge without mass diffusion | input_limited | |
| H_VIDEO | formation_chain | Device witness -> training or transmission -> workshop use -> population prevalence | input_limited | |
| H_VIDEO | fabrication_or_coordination_scope | not_required_by_claim_logic | not_applicable_by_claim_logic | |
| H_MAINSTREAM | necessary_condition | “宋代铁匠都能”是全称社会命题，须有跨地区、跨作坊和技能分布证据；单个工坊记录不足 | input_limited | |
| H_MAINSTREAM | positive_prediction | 技术扩散史应显示专门工匠/工坊分工、材料和训练要求，而非全体铁匠均可操作 | input_limited | |
| H_MAINSTREAM | disconfirmer | 若多地同时代记录明确普遍掌握且无专业分工，主流的有限扩散模型需重估 | input_limited | |
| H_MAINSTREAM | alternative_mechanism | “铁匠”类别被当成同质群体；设备可见不等于工艺知识普及；夸张修辞 | input_limited | |
| H_MAINSTREAM | formation_chain | 个别作坊/手工业记录→区域传播→群体技能分布→检验“都能” | input_limited | |
| H_MAINSTREAM | fabrication_or_coordination_scope | not_required_by_claim_logic | not_applicable_by_claim_logic |
