"""候选卡的取数层：把各条证据线从三处库读成"按前缀码索引的字典"（全部只读）。
|
||
|
||
## 为什么要有它
|
||
|
||
候选卡的规则在 card.py，是纯函数；证据从哪来、怎么对齐代码格式、缺了怎么办，
|
||
全部收在这里，plan.py 只做装配。三处来源：
|
||
|
||
基座 PG v_factor_transmission_moved 已启动成员及其所在环节的传导证据（只认 Segment 目标）
|
||
v_factor_stock_daily 数据日涨幅、主力净额异常值、热度变化
|
||
153 代理 strategy_daily_results 决策系统昨夜结论：信号、支撑压力位、吸筹块
|
||
（吸筹的评分、状态、评分日三项一次读齐；基座落库的吸筹版本没有评分日，所以不从基座取）
|
||
平台 MySQL gp_day_data 交易日历（算评分日龄用；取一只长期存在的票的日期序列）
|
||
基座 PG v_factor_logic 数据基座抽取的因果论断（方向、机制、时效、出处），每票最多几条，
|
||
只展示不作门槛（2026-09-03 方案第 3.3 节）
|
||
平台 MySQL zs_day_data / eastmoney_rzrq_data / fear_greed_index
|
||
计划环境段的市场四项：两市成交额、融资余额、恐贪指数；
|
||
市场广度从基座 v_factor_stock_daily 当日行自算（同一节）
|
||
基座 PG v_factor_judgement 产业研判与环节评析的最新一版结论（采信倾向、多空条数、
|
||
自我校验、材料指纹），每个计划日抄一份存版本史（judgement.py）
|
||
|
||
代码格式：基座是点后缀式 600000.SH，决策系统与桥是前缀式 SH600000，进出都过 common.to_prefix。
|
||
读失败的语义：每一路读不到都返回空字典并打印一行原因，候选卡按"缺失"处理（进关注或仅展示），
|
||
不让计划断产——与 pool.py 的安全边界一致。
|
||
|
||
离线单测：logic_claims 与 market_context 都接受注入的读函数（read_pg / read_mysql），
|
||
test_market_context.py 用假数据函数替换真实连接，不连库；两者内部只对"记录列表"做计算，
|
||
读函数返回 DataFrame 或普通的字典列表都可以（见 _records）。
