Validate externally referenced theorems by querying arXiv theorem search first and Codex's built-in web search second. Use when a markdown proof cites statements from external papers.
Validate every external-paper reference used in the proof.
For each cited external theorem/lemma/definition:
search_arxiv_theorems using the full referenced statement as query.reference_checks.Do not rely on dedicated comparison utility code; perform comparison through careful reasoning.
Append records to reference_checks like:
{
"location": "Lemma 2",
"referenced_statement": "Exact statement text",
"context_expansion": "In the cited paper, 'regular' means regular with respect to the valuation topology.",
"arxiv_match_found": false,
"web_match_found": false,
"critical_error": {
"location": "Lemma 2",
"issue": "Referenced external theorem was not found in arXiv search or Codex built-in web search."
}
}
