移除仓库中的商业数据:删掉 21 个相关用例,其余标识符脱敏

这个仓库是公开的,而历史里带着一份客户 BI 仓的逐字转储:ANALYTICS(原
schema 名)下 53 张视图名、实测行数、字段结构表,外加一句写明取数方是谁
的注脚。还有一处把真人姓名和工作单位写进了检查脚本的断言里。这些都不是
化名,是能直接拿去对库的东西。

按"含敏感词的测试直接删"处理,共 21 个用例:

  test_agent_tool_loop.py   整个文件(2 个,agent 工具循环的真图验收)
  test_conversations.py     9 个(会话 CRUD、历史文本、上下文进 prompt)
  test_datasource.py        5 个(探查失败的实情、候选 schema 提示)
  test_copilot_context.py   3 个(数据源摘要的限定名)
  test_review.py            1 个(干净运行无信号)
  test_tool_args.py         1 个(call_tool 端到端)

辅助函数和产品源码不在"测试"之列,改为脱敏——否则删一个 _seeded 会连带
带走 8 个没被点名的用例。标识符一律换成中性名:shop→shop、
ANALYTICS→ANALYTICS、prod_shop→prod_shop、真人姓名→张三。

markdown 样本里那两条不是改标识符能解决的:行数、字段结构、业务域描述
整段都是客户的。换成同构的合成内容——领域换了,markdown 构造逐项对齐
(标题层级、有序/无序列表、三列表、带 inline code 的单元格、引用块),
渲染器的覆盖面没有变窄。check-stream 里那句"用的是真实输出"跟着改成实话。

286 → 265 passed,差值正好是删掉的 21 个。tsc 干净,decode / stream / ui
三个 check 不回归。

历史里的同一批内容另行用 git filter-repo 处理。

"""Agent 的工具循环,跑真图验收。
单测能保证 split_tool_calls 分得对、prepare_args 纠得对,但保证不了它们在
run_agent 里被接对了。这里从 run_manager.start 进去、从落库的 RunEvent 出来,
验的是用户真正会看到的那条事件流。
两件必须守住的事:
- 每个 tool_use 都要有配对的 tool_result。少一条,下一次模型调用直接 400。
- 没执行的调用绝不能发 tool.start。前端靠 call_id 配对 start/end
(frontend/src/run/decode.ts),一条没有结尾的 start 就是界面上一个永远转圈的卡片。
