+- 2026-09-25, learned from titan's router (llama-server b10964) while v2 ran: in router mode a
+  plain `GET /props` answers `n_ctx: 0` (`role: router`), and `GET /props?model=X` **autoloads X**
+  when `models_autoload` is on — the same trap as `/slots?model=X`. Task 01's poller therefore
+  learns nothing on a real router and the guard stays inert there. Follow-up for v2.1: query
+  `/props?model=X` only for models `/v1/models` lists as loaded, never for others. Not a defect
+  in what the tasks asked for; a gap in what the owner knew when writing them.
