Theory of Generated Space — Superconductivity closure: a TGP-structured T_c formula across five families

Preprint and supporting numerical material for the TGP superconductivity-closure paper, a companion to the TGP core paper (Zenodo DOI: 10.5281/zenodo.19670324). The paper applies the substrate-field framework of TGP to the superconducting Tc: it derives a closed-form T_c expression calibrated on a five-d-metal subset, extends it across cuprates, MgB₂, hydrides and A15, and states explicit open sub-problems (Ce/Kondo regime, √n scaling). Structural coefficients κ_TGP ≈ 2.012 (spin-fluctuation coupling), β ≈ 2.527 (magnetic blocking) and α_PB ≈ 0.2887 μ_B⁻² (Abrikosov-Gorkov pair-breaking) are reported alongside the cross-sector universal constant c_TGP = 1/(4π) that reappears in the liquid-viscosity sector. The repository contains the paper source, compiled PDF, and the two numerical folders that are directly cited: superconductivity_closure/ (Tc formula, candidate scans, P6/P7 validation) and liquid_viscosity/ (η/s bound recovering the Kovtun-Son-Starinets floor).
