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 Tc 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 κTGP ≈ 2. 012 (spin-fluctuation coupling), β ≈ 2. 527 (magnetic blocking) and αPB ≈ 0. 2887 μB⁻² (Abrikosov-Gorkov pair-breaking) are reported alongside the cross-sector universal constant cTGP = 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: superconductivityclosure/ (Tc formula, candidate scans, P6/P7 validation) and liquidᵥiscosity/ (η/s bound recovering the Kovtun-Son-Starinets floor).
