SGUFT Thermo Consistency V9 (TH1): Horizon Thermodynamics & GSL-Proxy Closure (RUN_G_GRDEMO_0001_TH1)

This record provides a DOI-only, auditable evidence pack for SGUFT thermodynamic consistency check TH1 (G2 minimal thermo gate).The check is built on the FRW(k=0) apparent-horizon thermodynamic objects (radius/area/temperature proxies) and a conservative effective Planck-mass proxy reconstructed from V8 GWproxy-T1 αMproxy(a)\alpha_M^{proxy}(a)αMproxy(a).PASS/FAIL depends solely on frozen, derivative-free (or discrete monotonic) maxima with SHA256-manifest audit closure: Thermodynamic GR-limit residual rS(a)r_S(a)rS(a) between normalized entropy proxies SeffS_{eff}Seff and SGRS_{GR}SGR GSL-proxy monotonicity violation rmonor_{mono}rmono on the entropy proxy along the a-grid Drift bound max⁡∣M∗2(a)−1∣\max|M_*^2(a)-1|max∣M∗2(a)−1∣ from the reconstructed M∗2(a)M_*^2(a)M∗2(a) All required artifacts are included, with manifest_sha256.json, audit.json, and a hard-fail hashlink bridge (ref_bridge_v8.json) plus a rebuild script for reproducibility.
