fix(env): 钉死 pyright 的分析目标,修掉"无法解析导入 numpy/pandas"
现象:编辑器 / pyright 满屏 reportMissingImports,但 .venv 与 conda 环境里 import numpy, pandas 都正常,pytest 也全过。 根因两层: 1. pyright 没配 venvPath / pythonPath 时会去 PATH 上找 python。本机 PATH 上 唯一的 python 是 agent-tools 的 shim(Codex 运行时,Python 3.14),没有科学栈。 pyright --verbose 显示它选了 3.14.6,Search paths 里一个 Anaconda 路径都没有。 注意持久化的 User/Machine PATH 并没有这一项,是 Codex 进程临时注入的——所以 "我的终端没问题"和"工具有问题"可以同时成立。 2. .venv 是 --system-site-packages 建的,三方包在 D:\anaconda\Lib\site-packages, 而 pyright / Pylance 不认 pyvenv.cfg 的 include-system-site-packages, 只去 .venv\Lib\site-packages 找(那里只有 pip)。 pyright 不读 pyvenv.cfg,但**认 .pth**。 改动: - pyproject.toml [tool.pyright]:venvPath = "." / venv = ".venv" / pythonVersion = "3.13",并注释了为什么必须写 - scripts/setup-venv.ps1:新增第 [2/4] 步,自动往 .venv 写 _mcm_base_site_packages.pth 指向该机 base 的 site-packages,换机重建即可 - tests/test_data.py:3 处 isna().all() 断言外面套 bool()(它的类型是 Series | bool,直接当条件 pyright 报"条件操作数无效"); 2 处故意传错类型的用例加 type: ignore[arg-type] 结果:pyright 17 errors -> 0 errors / 0 warnings;pytest 两套环境均 40 passed, 44 skipped;ruff All checks passed;setup-venv.ps1 通过 AST 解析 (纯 ASCII + LF)。 文档:docs/04-environment.md 新增坑 7(含 pyright --verbose 诊断口诀与 VS Code / PyCharm 的操作步骤)、STATUS 决策 29、CHANGELOG。
