Every proposed change passes through an anytime-valid gate — a statistical checkpoint that only accepts a modification if it stays within a pre-set error budget and logs an auditable certificate when it does. Five verifier mechanisms supply the signal those gates need: best-of-N selection, micro-step search, self-authored reproduction oracles, search-layer control, and self-repair. None requires a separate grader; each works from the issue text alone.\n\nThe core problem SEA addresses is one the field has quietly sidestepped: standard learning-theoretic guarantees assume the data, evaluator, and hypothesis space are fixed — but a self-modifying agent violates all three simultaneously. By anchoring changes to what the frozen base model can already produce, SEA avoids generating genuinely new behaviors and instead selects among existing ones, which is where the certificate math holds.\n\nTested on a 52-instance subset of SWE-bench Verified across four base models, the architecture showed modest but isolated gains: the paper reports improvements of 4 and 5 percentage points on two stronger base models. The paper does not pin precise version strings for the models used — it names GLM 5.2 and GPT without a version suffix, and neither can be independently verified against a public model lineup, so those numbers should be read as directional. Base model capability was the dominant factor regardless, which the authors call a confound-free finding. Single-run results on expensive evaluations mean run-to-run variance is still unknown — a caveat the paper flags openly rather than buries.","[\"ai\",\"research\",\"agents\",\"safety\"]","2026-07-02T04:00:00.000Z","2026-07-02T04:23:40.801Z","2026-07-02T04:23:43.607Z","published",null,[24],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"The body names 'GLM 5.2' and bare 'GPT' as if they are specific, verifiable model identifiers, but neither can be confirmed against a vendor's publicly documented lineup — 'GLM 5.2' does not appear in Zhipu AI's confirmed public release history and 'GPT' without a version string is unresolvable; the writer must either pin the exact model identifiers (as the paper itself should have specified them) or explicitly note that the paper does not disclose the precise versions used.","resolved","ai",[30,32,33,34],"research","agents","safety",[36],{"name":37,"url":38},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2607.00871",0,{"sections":41},[42,46,51,56,61,66,71,76,81,86,91,95,100,105],{"name":43,"slug":30,"count":44,"latest_published_at":45},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":47,"slug":48,"count":49,"latest_published_at":50},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":92,"slug":93,"count":89,"latest_published_at":94},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":106,"slug":107,"count":108,"latest_published_at":109},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
