/**
 * ACL 判级单测（SPEC FR-20 / 《API-契约》§五）
 *
 * 🔴 判级移植自 v1 `fmode-app/src/app/core/acl.ts:50-69`，重点回归：
 *   ① **无 me → guest → `'mine'`**（安全默认，最不能错的一条）
 *   ② 超管优先于公司角色（且不要求有公司）
 *   ③ **管理员与成员必须区分**（company-admin vs company-member）
 *   ④ **当前**两者都请求 `'company'`（用户裁决：同公司就看全公司）
 *
 * 本判定只选「请求哪个 scope」，**不做视图放行** —— 见 acl.ts 注释。
