 "what": "The AlphaProof Nexus audit, kernel lane: each Erdős proof of google-deepmind/alphaproof-nexus-results @ 0647711a checked by Comparator v4.27.0 against formal-conjectures' own statement at the commit the repository builds against (7862bf6a), with nanoda on (.github/workflows/apn-kernel.yml). CERTIFIED here means the proof proves exactly that statement, uses only propext / Quot.sound / Classical.choice, and two independently written kernels accept it. Whether the statement is the problem Erdős posed is the reading lane's question.",
