Higher‑Dimensional Blast Cosmology (HDBC) v2.3 — Reproducibility bundle: official PISC/PLI overlays, DECIGO γ(f), sub‑mm α–λ CSVs, and ΔN_eff(a) track

What this record contains. A complete, reproducibility‑first bundle for HDBC v2.x: (i) official sensitivity overlays for LISA/DECIGO/B‑DECIGO (PISC/PLI kernels) via path‑driven loaders, (ii) a geometry‑exact DECIGO two‑cluster overlap function γ_KT(f) for D=1200 km, 60° arms, 15° tilt, (iii) sub‑millimeter gravity shading controlled by Eöt‑Wash/HUST α–λ CSVs, (iv) a ΔN_eff(a) track for BBN/CMB emulation, and (v) TeX appendices for the GS/Y basis, intersections, Yukawa matrices, and BBN posteriors. The manifest JSON specifies canonical paths; the README explains how to fetch/extract the official PISC/PLI/PSD tables so notebooks switch to “official” without any code edits. Files. • HDBC_v2_3_all_files.zip — bundle with /data/pisc_pli/ (fetch script & README), /data/submm_bounds/(Eöt‑Wash/HUST CSV placeholders), /yukawas/ (Yu, Yd, Ye, Yν), DeltaNeff_track.csv, GS/Intersections/Yukawa/BBN appendices. • HDBC_v2_2_camera_ready.pdf — camera‑ready summary with ΔN_eff(a) and γ(f) figures plus a quick table view. • README_pisc_pli.txt — how the official PISC/PLI/PSD layout is expected; fetch/extract steps. • fetch_pisc_pli.sh — one‑line downloader for the three official archives. How to switch to “official” kernels. Place the three archives from Schmitz’s Zenodo record (strain‑noise PSDs, PLI, PISC) into /data/pisc_pli/ and extract in place; the loaders already look there (see README_pisc_pli.txt; the manifest lists the canonical paths). Intended use. Reproduce SNR/PLI/PISC overlays (LISA/DECIGO/B‑DECIGO), re‑shade sub‑mm bounds from publication CSVs, and run BBN/CMB emulators from the ΔN_eff(a) track. License. Dataset CC BY 4.0.
