Headless research pass

The pass did not produce a valid research result: RuntimeError: Codex gpt-5.6-sol failed rc=0: ent harness. Web search checked the Covering Repository context, Gordon-Kuperberg-Patashnik, and arXiv:2607.23766. Exploratory Z3 4.13.0, CaDiCaL 1.7.3, and HiGHS 1.2.0 probes were timeout/unknown and are not evidence. No CAS, proof assistant, cloud lab, external proof service, or human validator produced a terminal certificate.\"\n}\n```"}} {"type":"item.completed","item":{"id":"item_1","type":"todo_list","items":[{"text":"Audit workspace, delegate memos, prior artifacts, and official/current status","completed":true},{"text":"Predeclare and implement the cheapest bounded discriminator with independent checks","completed":true},{"text":"Run the experiment through the reproducibility harness and attack the result","completed":true},{"text":"Write immutable evidence/checkpoint artifacts and report the exact scoped outcome","completed":true}]}} {"type":"turn.completed","usage":{"input_tokens":16116197,"cached_input_tokens":15840768,"output_tokens":64087,"reasoning_output_tokens":15889}}
