"""RW-018 研判的两个口径缺陷（docs/25 P2）。
|
|||
|
|
|
|||
|
|
1. **列表级无条件放行**：`_assess_list_rule` 收到 `item` 却完全不看它，对 RW-018
|
|||
|
|
一律返回"可考虑放行"，连理由文本都是硬编码的"现有摘要显示交易来自有效定投工单"。
|
|||
|
|
于是渠道不匹配、或证据里根本没有工单信息的预警，在列表层就被标成可放行 ——
|
|||
|
|
而列表正是风控专员最先看到的一屏。详情层另有判断，但那要等人点进去。
|
|||
|
|
|
|||
|
|
2. **详情级与扫描侧口径不一致**：扫描按 `work_order.channel in {"定投", "自动定投"}`
|
|||
|
|
生成 RW-018 预警（`risk_scan_service.py:294`），详情级却只认 `"定投"`。于是
|
|||
|
|
"自动定投"的预警会出现"扫描认为有效、详情认为未确认"的自相矛盾。
|
|||
|
|
|
|||
|
|
两条现在共用 `DIRECT_INVESTMENT_CHANNELS`，改这份常量即同时影响两侧。
