"""只读探查：第十五条豁免规则（持仓占比）所需的数据是否齐备。
|
|||
|
|
|
|||
|
|
只做 SELECT。结果写 `docs/evidence/exemption-data-probe.json`：
|
|||
|
|
|
|||
|
|
python tools/probe_exemption_data.py
|
|||
|
|
|
|||
|
|
要回答的问题：
|
|||
|
|
1. `fin_customer_profile.total_asset` 有没有值、是否为正；
|
|||
|
|
2. `fin_holding` 有没有行、`market_value` / `current_value` 是否可用；
|
|||
|
|
3. 库内是否存在 C3→R4 / C4→R5 的申购交易 —— 即这条豁免规则是否真的会被触发。
