Abstract

Revision 5: the twining (forger's) test shows the 27720 lock fails at all 25 non-identity classes of M24 (numerology by that criterion); Stream 3's CKN result; Stream 6's pre-registered verdict excludes the programme's extra-dimension prediction. The conjecture in its testable form does not survive existing data; the formal mathematics remains Tier A. The title is kept so that the work stays citable under its deposited name. We present a Lean 4 companion formalization for a dual-scale scenario of type II string theory on $K3× T^2$, and we state precisely what is, and is not, machine-checked. The Mathlib-free core of the Lean artifact (51 files, 554 declarations, toolchain v4.33.1, no external dependency, standard axioms only — #print axioms logs in ) certifies exact integer and rational identities used in the argument: the positivity of the dual scale $R+\alpha'/R$ on integer radii; the $K3$ topological invariants $\chi=24$, $\sigma=-16$, $\mathrm{ind}(\slashed D)=2$; the elliptic-genus arithmetic $\mathcal A_2\cdot 60 = 4\mathcal A_1\cdot 77 = 27720$ with $|M_{24}| = 27720\cdot 8832$; and a corrected, genuinely unique-minimum toy potential (an earlier revision of this corpus contained a Nat-truncation bug that made the claimed minimum non-unique; and document the fix). Two further Lean libraries, built on Mathlib (which contributes no axioms beyond Lean's own three standard ones for the fragments used here), extend this core: StringTheoryFormalization (Stream 1's sixth library, corrects the $M_{24}$ representation table used in the moonshine arithmetic, ) and the new DualScaleStream2 library (99 theorems, 19 modules), which formalizes the $O(d,d;\mathbb Z)$ T-duality group, the Double Field Theory generalized metric, and the $K3× T^2$ lattice layer (); together with the original core, the audited total is 326 theorems (Stream 1, six libraries) and 99 theorems (Stream 2), 0 failing, standard axioms only. The differential-geometric, index-theoretic and cosmological statements built on top of this arithmetic — Double Field Theory, the Atiyah–Singer index theorem, moduli stabilization, and the tensor-to-scalar ratio, CP phase, and dark-energy predictions — are either drawn from the literature or proposed here as conjectures, and are labeled by epistemic tier throughout (\tierA\ / \tierL\ / \tierC). In particular we discuss the obstruction that $\mathcal{N}=4$ non-renormalization poses for moduli stabilization on $K3× T^2$, and we confront the paper's speculative numerical relations for $r$, $\delta_{\mathrm{CP}}$, and $(w_0,w_a)$ with current data, including the DESI DR2 preference for a time-evolving dark-energy equation of state at $3.1\sigma$ over $(w_0,w_a)=(-1,0)$. We close with a roadmap for promoting the central real-analytic claims (currently Tier L or Tier C) to kernel-checked Tier A theorems using Mathlib — a roadmap Stream 2 has already begun executing. Revision 5 — verdicts. Three later streams of the same repository test this paper's claims, and we report their outcome here without softening it. (i) The twining ("forger's") test: the ratio form of the "27720 lock" of , recomputed from $M_{24}$-twined McKay–Thompson series, fails at all 25 non-identity conjugacy classes of $M_{24}$; the lock remains a correct arithmetic identity (Tier A) but, by the criterion that separates moonshine from numerology, it is numerology, and we withdraw every structural or physical reading of it (). (ii) The literal dual-scale hypothesis fails the Cohen–Kaplan–Nelson bound by a factor $\ge10^{30}$. (iii) The programme's only experimental prediction — the self-dual length $\sqrt{\ell_P c/H_0}≈47 μ$m read as the radius of one large extra dimension — was frozen before comparison (disclosed as a retrodiction) and is excluded by the Eöt-Wash 2020 bounds and fails the neutron-star bound; the programme's own T-duality fixes the $O(1)$ factor that could have rescued it (). The zero-free-parameter cosmological conjecture, in the only form in which it makes a testable prediction, does not survive existing data. The formal mathematics (Tier A) is unaffected: as of release v3.14.0 the repository totals 611 audited theorems across ten libraries, 0 failing, standard axioms only. Epistemic tiers. Claims are labelled Tier A (checked by the Lean 4 kernel; axioms propext, Classical.choice, Quot.sound only), Tier L (literature, cited) or Tier C (conjecture). Only Tier A statements are machine-checked; physical interpretation is not. Lean artifact: SocrateAI-Scientific-Agora-LeanMaster, tag v3.17.0 (Lean 4 v4.33.1, Mathlib). Release gates on this tag: all ten libraries build; 621 theorems pass #print axioms with standard axioms only; no sorry/admit. AI-assisted tooling (Anthropic Claude models) was used in preparing the formalization and the manuscript, under the direction of the author.
