"""校验 RBAC 权限号段的一致性（只读，不连数据库）。
|
||
|
||
## 为什么需要它
|
||
|
||
权限码的**定义源**是 `tools/seed_test_rbac.py` 的 `PERMISSIONS` 常量 —— 因为那个脚本是
|
||
**DELETE 重建**语义：
|
||
|
||
```
|
||
DELETE FROM sys_permission WHERE id BETWEEN 9001 AND 9099
|
||
```
|
||
|
||
任何没并进 `PERMISSIONS` 的权限码，重建一次就没了，表现是"接口突然 403"，
|
||
而且**没有任何报错线索**。
|
||
|
||
2026-09-12 出过一次真实事故：库里有一批 `9020-9035` 是 `grant_advisor_role.py` 用**旧号段**
|
||
建的，而投顾线把 `9020-9034` 写进了种子 —— 两套 **id→code 映射不同**。种子的清理只清
|
||
`role_id 9001-9003` 的角色绑定，`advisor`(9004) 的绑定**不在清理范围内**，于是重建后
|
||
advisor 会静默拿到**语义完全错误**的权限组合（例如 id 9020 从 `asset-allocation:generate:self`
|
||
变成 `investment-goal:write:self`），全程不报错。
|
||
|
||
本脚本把这条约束变成可自动检查的四条：
|
||
|
||
1. 种子内 id 不重复；
|
||
2. 每个 `grant_*.py` 声明的 `(id, code)` 都能在种子里找到**完全一致**的一条；
|
||
3. `CUSTOMER_PERMISSIONS` 引用的 id 都存在；
|
||
4. 各 `grant_*.py` 之间不抢同一个 id。
|
||
|
||
`tests/unit/tools/test_rbac_seed_consistency.py` 会调用它，所以这四条是纳入门禁的。
|
||
|
||
用法：python tools/check_rbac_seed_consistency.py
