Higher‑D Leakage: Cross‑PTA fits, LISA overlay, and CMB TB/EB forecast — Last‑Mile bundle

**Higher‑D Leakage: Cross‑PTA fits, LISA overlay, and CMB TB/EB forecast — Last‑Mile bundle** This deposit contains a compact, reproducible release of our analysis pipeline and outputs:- Scripts to reproduce the figures and tables,- Templates for PTA/CMB/LISA/SUSY inputs (CSV),- Cross‑PTA best‑fits and ΔBIC (JSON/CSV),- NG15 and PTA→LISA overlay figures,- TeX boxes (Grand Equation + TB/EB Fisher),- A manifest of SHA‑256 checksums. See `README_ZENODO.md` and run the exact commands in `RUN_COMMANDS.txt`.If you replace the template CSVs with your collaboration’s inputs (EPTA/PPTA KDE ZIPs, per‑bin CSVs, or covariances), the same commands will regenerate all plots/tables with your numbers. **Version:** v2025.09.06**License:** Data & text — CC BY 4.0; Scripts — MIT (see `LICENSES/`). **Reproducibility checklist**- Record the exact CSVs/ZIPS you used for EPTA & PPTA in the Zenodo description.- Keep `CrossPTA_bestfits_*.json` and `CrossPTA_BIC_table_*.csv` in the deposit.- If your instrument N_ℓ or PI LISA curve differs from the templates, note that in the description.
