SGUFT G-closure V8 (PERT1): FRW Scalar Perturbation Closure + GWproxy-T1 Tensor Verdict (with cT/αM/M*² External Compare) — RUN_G_GRDEMO_0001_PERT1

This record provides a DOI-only, audit-ready evidence pack for SGUFT G-closure perturbation layer V8 (PERT1).It demonstrates FRW scalar perturbation closure (growth factor) and upgrades GWproxy-T1 (tensor proxy) to a PASS/FAIL adjudicated criterion, with a separate external_compare section for more physically interpretable EFT quantities (cT, αM, M*²) and observational-constraint references not used for the verdict. Included uploads (filenames frozen for reproducibility indexing) RUN_G_GRDEMO_0001_PERT1_pert1_only_pack_v1.zipMinimal reproducibility pack: frozen policies/specs, scalar + GWproxy outputs, audits, and SHA256 manifest. RUN_G_GRDEMO_0001_PERT1_pert1_evidence_pack_v1.zipFull evidence pack: includes build scripts, configs, logs, and the complete audit/manifest chain. V8_delivery_PERT1_summary_pack_v1.zipReader-facing summary (CSV/JSON) + generator script for quick verification and indexing. Verdict policy (hard / minimal / auditable) PASS/FAIL is determined solely by: Scalar closure: max_r_D
