+- 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.
+- 2026-09-25, task 05, first session: ended after 12 seconds. It misspelled the repository path
+  (`/home/kyle/src/crossar/Makefile`), the sandbox refused the out-of-repository read, and it
+  ended its turn — the sixth refusal-ending tonight, this one triggered by its own typo. Model
+  fault; no change to the task. Restarted.
+- 2026-09-25, task 05, second session (30 min in, wiring written, smoke check 3 failing): the given
+  `tools/smoke.sh` passed a 300 KB prompt as one `curl -d` argument, which Linux caps at 128 KiB
+  per argv element, so check 3 could never pass. Test fault (mine): the body now goes through a
+  file (`-d @file`). Ornith diagnosed it correctly. Resumed from the working tree with the
+  corrected script.
