"""创作知识 query 正交 demo：5 套家族机械正交 → LLM 只做排除(query_filter.txt) → 存 JSON。

不真实搜，只产 query 供前端看。轴严格取分类树的"创作支"：
  实质 = 实质树·理念支(排除表象)   形式 = 形式树·架构支(排除呈现)
  目的池 = 作用树 + 感受树 + 意图树 全部合一(随机取)
  创作阶段 = 灵感/选题/脚本(不补)  知识类型 = 怎么做/有哪些/为什么
5 家族：① 实质×形式 ② 实质×目的池 ③ 纯形式 ④ 形式×目的池 ⑤ 创作阶段×实质，各 20 条。
每条原串过 query_filter.txt(keep/排除)，存 keep+reason 供前端展示。
用法：PYTHONPATH=. CK_ENV_FILE=.env python scripts/build_creation_demo.py
