+##### [GET] /console/api/setup
+**Get system setup status.
+
+    NOTE: This endpoint is unauthenticated by design.
+
+    During first-time bootstrap there is no admin account yet, so frontend initialization must be
+    able to query setup progress before any login flow exists.
+
+    Only bootstrap-safe status information should be returned by this endpoint.

+##### [POST] /console/api/setup
+**Initialize system setup with admin account.
+
+    NOTE: This endpoint is unauthenticated by design for first-time bootstrap.
+    Access is restricted by deployment mode (`SELF_HOSTED`), one-time setup guards,
+    and init-password validation rather than user session authentication.
