+    - 新增 `POST /api/admin/session/login`
+    - 新增 `POST /api/admin/session/logout`
+    - 管理态受保护接口现已同时接受：
+      - `Authorization: Bearer <SUB2API_CRM_ADMIN_TOKEN>`
+      - 或同域管理员 session cookie
+    - `providers.html` 与 `admin-batch-import.html` 现已优先走 session，token 输入框仅保留为兜底
+    - 当前部署环境可通过以下变量显式配置管理员账号：
+      - `SUB2API_CRM_ADMIN_USERNAME`
+      - `SUB2API_CRM_ADMIN_PASSWORD`
+      - `SUB2API_CRM_ADMIN_SESSION_TTL`
 - 2026-05-26 已把“最终用户 -> 公网域名 -> OpenClaw”这一跳补进正式验证口径：
   - 公网根地址当前统一为 `https://sub.tksea.top`
   - OpenClaw 本地 `MiniMax` 运行时故障已定位为 `pi-ai/openai-node` 未继承系统 `HTTP(S)_PROXY`，不是 allowlist 或模型名大小写问题
