## 任务定位
从第二章正式内容抽取的开放研究任务，不是新的 Canonical 推导。
## 当前进展
给定外部模型的两种径向长度已有解析式，光子球与捕获尺度也已求出；边界单元计数给出面积熵，固定参数序列给出温度与第一定律。未闭合的是终止边界的形成动力学、微态容量、相关修正及边界—外场联合演化，不应把这些缺口写成上述解析结果尚不存在。
## 必须完成的环节
从纵横场作用量、源边界条件和稳定解推出强场 X、径向尺度及标准过程耦合，说明哪些系数由微观结构固定。
## 可交付结果与边界
可审查作用量、场方程、外部解、弱场匹配及稳定性分析；分别报告采用的输入与导出的量。
弱场红移不能唯一选择完整强场函数；给定函数的 X=0 不单独证明边界形成。
## 来源与协作
