step2_write_chapter.py 在 sys.path 加入 prevent-ai-flavor / diagnose-ai-flavor，新增「1.5) 人感前置预防」环节——生成前调用 build_prevention_contract（负约束+声音账）冻结进 WriterContext，并把 diagnosis 列为 shadow 候选的伴随检测。step2a_retrofit_ch1_context.py 相应补回退补写。 脚本只做拼装与持久化触发，五技能合同与 hard gate 由各自 skill 把守。 人感体系资产层仍由 humanization/ 维护（example 自治）；本脚本只消费。

"""真写一章 · 阶段二a 补建：第 1 章的开篇上下文与冻结记录。
|
||
|
||
原则：不存在没有上下文的写作。第 1 章之前也有设定、大纲、细纲——它的上下文是
|
||
asOf=0（开篇前冻结线）：证据只有设定包与细纲宣告的新事实，历史正文基线为空。
|
||
此前第 1 章按"基线章无上下文"的旧口径写成，看板运行详情因此缺一块上下文冻结；
|
||
本脚本按合同补建真实的第 1 章上下文并落冻结行（append-only，幂等），补齐记账。
|

|

只组装 + 落冻结，不改写第 1 章正文（正文早已接受为正式内容）。
