This document records a systematic literature search (arXiv, PRD, JHEP, Lattice QCD review series) aimed at locating independent, first-principles verifications for three core UIDT parameters currently classified as Category A-, C, or D. The goal is to identify upgrade paths toward Category B (lattice-compatible) or Category A (rigorously proven).
All cited sources have been verified for real existence (DOI or arXiv identifier). No fabricated references.

An independent FRG or lattice derivation of a universal dimensionless ratio of comparable magnitude (~16) linking the non-perturbative spectral gap to kinetic vacuum expectation — without prior knowledge of the UIDT value.

Stratum I/II finding: The FRG and lattice programs produce scheme-dependent IR coupling values. For near-conformal SU(3) theories (N_f = 10–12), these range from g²★ ~ 5.5–15.0 depending on scheme and fermion content (arXiv:2306.07236; PRD 109, 114507). Pure Yang-Mills (N_f = 0) is confining — no IRFP exists; instead, the running coupling diverges in the IR.
Stratum III (UIDT): γ = 16.339 is derived internally via a Banach fixed-point argument on the UIDT field equations. It does not correspond to any directly measurable scheme-independent lattice coupling.
Tension: The nearest lattice result (g²★ = 15.0(5) for N_f=10, arXiv:2306.07236) is numerically close to γ but:
- Applies to a near-conformal theory with 10 flavors, not pure YM
- Is scheme-dependent (GF scheme)
- Does not correspond to the UIDT physical interpretation
[TENSION ALERT] Numerical proximity (g²=15.0 vs γ=16.339) is noted. Difference: Δ = 1.34. No physical identification is justified without independent derivation.
Upgrade path to Category B:
- Compute the ratio Δ★/v (UIDT spectral gap / vacuum scale) via independent lattice simulation of pure SU(3) Yang-Mills using gradient flow renormalization
- Identify whether any scheme-independent combination of gluon propagator parameters reproduces γ without input
- Candidate observable: ratio of Gribov mass parameter γ_GZ to dynamical gluon mass m_gl in the Refined Gribov-Zwanziger framework (see arXiv:2402.17534)
A lattice QCD study or topological QFT analysis producing a torsion-related binding energy or entropic stabilization increment in discrete vacuum configurations at the MeV scale.

Stratum I finding: Lattice QCD establishes that topological vacuum structures (instantons, center vortices, monopoles) are real and physically relevant. However, all measured energy scales are at or above Λ_QCD (~200 MeV). No dedicated study of a torsion-specific binding energy at the MeV scale exists in the reviewed literature.
Stratum III (UIDT): E_T = 2.44 MeV is calibrated from cosmological constraints (Category C), not derived from Yang-Mills axioms.
Correct epistemic status: C/D — physically motivated but without lattice verification.
Upgrade path to Category B:
- Design a dedicated SU(3) lattice simulation targeting discrete torsion operators (analogous to the center vortex operator but tracking holonomy twists)
- Measure the free energy difference between topologically twisted and untwisted sectors in the MeV regime (small physical volume, fine lattice spacing)
- Reference methodology: 't Hooft twisted boundary conditions on small lattices (see Lucini et al. 2020 for technique)
A formal QFT result establishing a thermodynamic noise floor or computational censorship limit at ~17.1 MeV in strongly interacting sectors — analogous to the Wolpert-Bennett thermodynamic limit for computation.

Stratum I finding: The nuclear liquid-gas phase transition at T_c ≈ 15 MeV (Stratum B) is the closest known physical phenomenon at the relevant energy scale. It is numerically proximate to 17.1 MeV but is a thermodynamic phase transition, not a computational censorship limit.
Stratum III (UIDT): The 17.1 MeV value is a prediction (Category D) without external anchor.
No Wolpert-limit analogue in QFT at the MeV scale has been found in the literature.
Upgrade path to Category D→B: This is the hardest upgrade. It requires:
- Formal extension of Wolpert's stochastic thermodynamics framework to infinite-dimensional QFT Hilbert spaces (open mathematical problem)
- Identification of a specific IR cutoff mechanism in strongly-coupled YM that produces a computational irreducibility bound at this scale
- Independent publication and peer review of the extension before UIDT can cite it as Category B
