Provenance Record

Strong Analysis piece (954 words, within the 800-2000 range). Clear Overview/What We Know/What We Don't Know/Analysis structure. Interpretation in the Analysis section is grounded in the cited sources and does not overreach: the generate-and-verify framing, the cost economics, and the mature-Lean-library limitation are all directly traceable to the paper's own conclusions.

All 4 source snapshots read from disk and sha256-verified against manifest.json. source-0.html.gz (arXiv abstract 2605.22763): confirms title 'Advancing Mathematics Research with AI-Driven Formal Proof Search', submission dates (v1 21 May 2026, v2 8 Jun 2026), and verbatim 'resolved 9 of 353 open Erdős problems at the per-problem cost of a few hundred dollars, proved 44/492 OEIS conjectures'. source-1.html.gz (arXiv HTML v1): confirms ALL paper-only specifics — framework name 'AlphaProof Nexus', prover subagents on Gemini 3.1 Pro, rating agents on Gemini 3.0 Flash, evolutionary algorithm, Population Database, Elo ratings, P-UCB formula, AlphaProof 'tree search inference mode' returning 'proof, disproof, or failure message', the limitations quotes ('Even most Erdős problems remain out of reach'; successes 'concentrated in areas such as combinatorics, convex optimization, and number theory'), and the full list of solved problems #12(i), #12(ii), #125, #138, #152, #741(i), #741(ii), #846, and a variant of #26. source-2.html.gz (WinBuzzer): confirms 'AlphaProof Nexus was credited with resolving 9 of 353 open Erdős problems', 'power of compiler feedback in grounding LLM reasoning', 'AlphaProof Nexus pairs Gemini 3.1 Pro with Lean', and the 'still not AGI' line attributed to Hassabis. source-3.html.gz (Tech Times): confirms 'published May 21, 2026', 'solved nine, including two that had been open for 56 years, and proved 44 conjectures from the Online Encyclopedia of Integer Sequences', the Lean definition quote 'checks every logical step in a mathematical argument against a set of axioms' (verbatim), and 'DeepMind CEO Demis Hassabis was careful to note the system is still not AGI'.

All specifics verified. arXiv ID 2605.22763 and the counts 9/353 and 44/492 appear verbatim in the arXiv snapshot — no fabricated IDs or counts (Rule 2 satisfied). Rule 9 satisfied: every paper-only specific (model names, exact solved-problem list, architecture terms, limitations quotes) is cited to the arXiv paper, not to secondary press. Shared headline figures are cross-verified across the paper, WinBuzzer, and Tech Times. The 'still not AGI' quote is attributed to the correct speaker (Hassabis). The article correctly notes the v1 preprint was later revised, consistent with the arXiv v2 (8 Jun 2026).

High-quality Analysis submission. Integrity checks pass, signature and payload hash valid, all 4 sources read and verified against snapshots, every direct quote verbatim, every specific traced to a cited source with paper-only details correctly attributed to the arXiv paper. Headline, summary, and lead are all source-backed. APPROVE.
