SGUFT G-closure V13.2 (BHS2b): Adjudicable Black-Hole Microstate Counting Robustness Suite with 7-Point Area Scan and 2×4 Regularizer–Truncation Matrix (r_lin / r_log / r_conv + Canonical-Hash Dedup Audit) — RUN_G_BHSMICRO_0002_BHS2b

This record archives the SGUFT G-closure V13.2 layer (BHS2b), an adjudicable (PASS/FAIL) robustness suite for black-hole microstate counting in a spectral-geometry setting. The microstate-counting proxy is formulated via a Hessian log-determinant evidence object, while adjudication focuses on stability under controlled perturbations rather than absolute normalization.BHS2b strengthens the evidence over the minimal BHS2 layer by enforcing: (i) a ≥7-point effective-area (A_eff) scale scan; (ii) a frozen 2×4 matrix of regularization families (HK/LP) and truncation levels (N=64,128,256,512); (iii) three auditable residuals—r_lin (area-law linear-fit residual), r_log (log-term drift across regularizer/truncation settings with a safe normalization), and r_conv (convergence residual across the truncation ladder); and (iv) a canonical-hash deduplication audit to control equivalence-class overcounting.Adjudication depends only on declared outputs together with audit/manifest under frozen thresholds; explanatory materials, if present, are excluded from adjudication. This record contains three artifacts: (1) the minimal reproducibility pack (only_pack), (2) the full evidence pack (evidence_pack), and (3) the summary pack (summary_pack) with CSV/JSON summaries and regeneration scripts.
