Not evaluated
Random-SAT thresholds, sharp variance and computability (family 235)
The gist
OpenAI claims, in four manuscripts announced on October 6, 2026, results on the satisfiability threshold and on the variance of the random k-SAT hitting time.
DiscoverIA status on October 12, 2026: not evaluated, meaning no third-party evaluation found.

What it changes
If the manuscripts hold, they would provide a limiting satisfiability threshold for each fixed clause size and a linear variance of the hitting time for random 3-SAT. The titles do not say which parameter this linearity refers to.
What remains unclear
It is not known whether a third party has evaluated these manuscripts: no evaluation is recorded in the sources read. The Lean (a language in which a computer checks every step of a proof) is supplied by OpenAI itself, and formalization.yaml marks its review as 'unchecked'.

Method
Four manuscripts in OpenAI's repository, dated September 25, September 27 and October 5, 2026, deal with the threshold and the variance; one is titled 'Computing the Random 3-SAT Threshold'. The file lean/docs/235.md describes the scope of the Lean formalisation, with 4 Comparator statements. DiscoverIA status: not evaluated, meaning that no third-party evaluation has been found in the sources read. Set on October 12, 2026 from github.com (page read, quotation checked word for word: “describes the scope of the Lean formalization”).
Limits
No named third party: the recorded checks come from the claimant or from a platform tool. The claimant supplies a Lean proof; as of this date, DiscoverIA has found no independent verification of this proof or of the result.
