Data & Repro Pack (REALDATA, LISA 10-yr + confusion): Brane-world unification — one λ links a GW break and ΔN_eff

Machine-readable files and compact figures to reproduce the REALDATA pass of“A testable brane-world unification: one parameter links a GW spectral break and ΔN_eff”(Maldonado, 2025). The pack includes the wide, margin-safe Two-Pager, PTA/LISA quick-lookPNGs, best-fit JSON, Planck prior JSON, and MANIFEST/CHECKSUMS. Physics summary---------------We model the universe as a 4-D brane in a higher-D bulk. The effective FRW equation on the brane isH^2 = (8πG/3)·ρ·(1 + ρ/(2λ)) + Λ4/3 + C/a^4 (flat, k=0).Two near-term tests follow:(1) GW spectral break: f_br(λ) ∝ λ^(1/4) (transition ρ^2 → standard 4-D). Tested with PTAs now and LISA next.(2) Early-radiation excess: C/ρ_γ,0 = (7/8)·(4/11)^(4/3)·ΔN_eff constrained by CMB/BBN. REALDATA pass (illustrative numbers)------------------------------------Break frequency: f_br ≈ 7.96×10^-9 Hz (68% band: illustrative) Slopes: m1 ≈ −0.92, m2 ≈ −1.52 Prior used: Planck 2018 ΔN_eff = 2.99 ± 0.17 Contents--------• Results_TwoPager_REALDATA_WIDE_FINAL_20250815_v4.pdf (equations + PTA/LISA overlays, margin-safe)• PTA_fit_preview_REALDATA_WIDE_20250815_INST_ONLY.png• LISA_sensitivity_overlay_REALDATA_WIDE_20250815_INST_ONLY.png• BestFit_with_uncertainties_20250815_071832.json (central values + 68% ranges)• CMB_Planck2018_DeltaNeff_prior.json (prior used)• MANIFEST_Zenodo_REALDATA_20250815_v2.txt• CHECKSUMS_Zenodo_REALDATA_20250815_v2.md5(optional) • Zenodo_Data_Repro_Pack_REALDATA_20250815_v2.zip (same items as a single upload) Column schema-------------PTA CSV (if included): freq_Hz [Hz], log10rho_median, log10rho_p16, log10rho_p84LISA CSV (ESA-style, if included): f_Hz [Hz], Sn_1_per_Hz [1/Hz], label [string] How to reproduce (minimal)--------------------------1) Load the PTA CSV and fit a broken power law in log10rho(f) with a single break frequency f_br.2) Compare to BestFit_with_uncertainties.json (central values + 68%).3) Overlay any LISA CSV variant for sensitivity context.4) The Two-Pager is generated directly from the files in this pack. “This version includes a margin-safe Two-Pager and a 10-yr + confusion LISA overlay swap-in (same filenames for replace-in-place).” “This version refreshes the Two-Pager and previews with the LISA 10-yr + confusion overlay, adds a margin-safe MASTER (4 pp), and provides an optional corners repro pack (samples + 1D/2D plots).”
