Method

Status “not evaluated” recorded on 12 October 2026 from github.com (page read, quotation checked word for word).

Limits

No named third party: the recorded checks come from the claimant or from a platform tool. A Lean proof supplied by the claimant does not count as formal verification by a third party. DiscoverIA has recorded no independent evaluation as of this date.
