全部主张 / 机械、电学与发明史

瓦特本人承认自己对蒸汽机所做的是改良

当前输入不足以比较R005-SEG003-C1703:00-03:59

该主张在“支持 / 未定 / 反对”上的当前位置，不是概率，是本轮证据规则下的比较终态。

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。

用户档位：未映射

当日视频这一批命题的台账里没有“证据方向”和“证据强度”两列，而用户档位正是由这两列推出来的。两条轴之间不存在函数关系，硬套就是发明数据，所以本站不给这一批命题标档位。

要给它一个档位，需要按同一套规则对它独立重判：写出正向证据、反证、已查检索面和判定稳度。这条动作还没有做。

另两批命题为什么有档位、这套档位怎么定的，见方法与边界。
