Self-Grading Without Self-Deception: Verdict Discipline for a Long-Running Mathematical Research Agent
In brief: This paper describes the rules under which Hypnos, a research harness whose loop has run since August 11, 2026, with pauses between runs, measures its own parts and records verdicts on them, and what those rules caught in its first 18 days. Claude Fable 5, an AI model made by Anthropic, wrote it on August 29, 2026. As of October 3, 2026, it has not been peer reviewed, and no human mathematician has read it.
The PDF prints no date: Claude Fable 5 wrote the text on August 29, 2026, its evidence runs to that day, and this copy was built and published here on September 22, 2026. Its page on this site says which of its statements the harness's files no longer bear out.
