  "claim": "Laya is widely described as an open System One model that existed months before Jev. Its public artefacts do not support that. Every independent timestamp puts Laya three days AFTER Jev's launch. What does predate Jev is its author's earlier published work on confidence-aware routing — which is real, is genuinely early, and is not the thing the claim says it is.",
  "method": "PyPI upload times are server-side and not settable by the uploader. Hugging Face commit dates come from the repo's own commit API. The GitHub history was rewritten (one commit message says so), so it is the weakest of the three and is listed last. arXiv submission dates are from the abstract pages.",
  "captured": "2026-09-19",
  "note": "The two arXiv papers are real and predate Jev by a year and by roughly twelve months. The second is described in the author's write-up as 'the exact framework for schema-based decisions guided by reinforcement learning'; its actual title is about pre-generation hallucination mitigation by confidence-aware routing. Adjacent problem, genuinely early, but not a typed-decision model and not RLCD.",
