The paper introduces a source‑grounded framework that represents mathematical arguments as directed acyclic graphs, incorporating numbered and unnumbered statements, equations, assumptions, and constructions while distinguishing source occurrences from contextual states and inference records. It defines measurement metrics such as depth (longest prerequisite path) and bulk (distinct ancestor edges), and provides a standardized, versioned prompt protocol for annotation discovery, deterministic recomputation, and review assistance. The framework also supports cross‑paper links to explore theorem co‑use, rare combinations, and dependency communities, aiming to motivate probabilistic premise suggestions and review of omissions or unchecked conditions in both human‑written and AI‑generated proofs.

LeanGraphSearch is a graph‑based retrieval method for the Lean 4 theorem prover that builds a dependency graph from Mathlib’s forward dependencies and traverses it to find supporting lemmas via multi‑hop chains. By linking each declaration to its premises, propagating relevance through a graph‑ranking algorithm, and re‑ranking candidates against the original query, it improves recall by up to 12% over LeanSearch v2 on MathlibQR and increases coverage of complete annotated proof routes on MathlibMPR by up to 3.7%. When integrated into an iterative proving loop, LeanGraphSearch raises pass rates at 8, 16, and 32 reflection turns by as much as 40% compared to a vanilla prover and up to 10% compared to LeanSearch v2, demonstrating higher accuracy‑cost efficiency.

The paper introduces OpenConjecture, a dataset of mathematical conjectures from arXiv papers since February 2026, and evaluates frontier GPT models on 200 randomly sampled conjectures. The models generate candidate solutions for about 60% of the conjectures, with counterexamples occurring roughly 1.3 times more often than proofs. The study examines solution novelty, citation practices, and fidelity to the original statements, finding that some solutions deviate from authors’ intent and that many proofs closely follow existing results, though some exhibit moderate novelty.
