"""sources.market_context 与 sources.logic_claims 的离线单测（不连库），另带复盘脚本的台账标题解析。

取数函数都接受注入的读函数：这里用返回字典列表的假函数替换 db.read_pg / db.read_mysql，
覆盖：两市成交额与前五日比值、日期筛选、两市不齐全的日子被跳过；广度四项；融资与恐贪按最新
一行取且日期列自动探测；每一项读失败为空不阻断；因果论断按前缀码索引、只取披露日不晚于
数据日的、每票最多三条按披露日倒序；读失败返回空字典。

开发机没有 pandas 与数据库驱动时，只给缺席的模块装最小桩（与 test_plan_verdict.py 同一约定：
仅在模块缺席时装桩，不覆盖真实模块），取数函数的计算部分不碰 pandas。

跑法：python3 test_market_context.py   或   pytest test_market_context.py
