This erratum clarifies the physical interpretation of the UIDT mass gap result ∆ * = 1.710 ± 0.015 GeV in light of recent lattice QCD findings. Following Morningstar (2025), arXiv:2502.02547, we emphasise that the mass gap represents the spectral gap of pure Yang-Mills theory, not an observable particle mass in full QCD. All mathematical proofs remain valid and unchanged. Only the physical interpretation requires clarification.
