"""造 RBAC 测试数据，验证真实链路身份加载与越权拦截。

数据使用 9001/9002/9003 号段（角色、权限分别用 9001 起的独立号段），便于清理，
不影响业务数据。

为什么需要这份种子：权限码必须与**代码实际声明**一致——工具声明写在
`app/service/agent/bootstrap.py`（`check_suitability` 需 `suitability:read`、
`query_fund_quote` 需 `fund:quote:read`），接口校验写在各 Service 的
`AuthorizationService.require(...)`。种子缺权限的后果不是"少测一项"，而是
"功能明明实现了却一直 403"，让验收与集成测试得出错误结论。
