Finding from the local real-server adversarial run on 2026-09-26.

During tests/adversarial/attack2.py Unicode-title checks, two note retitle requests (Unicode Note 1 retitle and Unicode Note 2 retitle) returned no response before the HTTP client timeout. The probe was running on a heavily loaded shared host (load average reached 60, with several Calternal servers and adversarial jobs active).

These are non-SLOW results because the client received no response. Reproduce note retitle on a quiet host and verify each write responds and persists the requested title.

Additional evidence from the same run: Unicode Note 3 and Unicode Note 5 creation did not return HTTP 201, so the probe’s note() helper returned None; another retitle (Unicode Note 4) hit the client timeout. The probe does not report the two create statuses, so I am recording only that they were not 201. Host load reached 74 during these requests.

The completed probe ended with the following Note write results: retitles 1, 2, and 4 timed out; Note creates 3, 5, 7, and 8 did not return HTTP 201 (the probe helper returned None); retitle 6 succeeded in 20.5 seconds. Host load was above 70. This is the full set of Unicode Note write anomalies from the run.
