Listening Beyond Four Dimensions: Higher‑Dimensional Blast — vNOW Status Snapshot & Tool‑Kit

NEXTLEVEL higher‑D blast vNOW (status + tools) – This Zenodo record collects the current status of a falsifiable higher‑dimensional “blast” scenario for the origin of our observable Universe. In this picture, a short and violent episode in a higher‑D phase seeds a cosmological stochastic gravitational‑wave background (SGWB) with a smooth broken power‑law (SBPL) spectrum whose knee lies in the nanohertz pulsar‑timing array (PTA) band. The accompanying files provide: (i) a machine‑readable grand‑status JSON with all gate values (PTA knee cross‑coherence PCI, ΔN_eff, LVK SGWB safety, black‑hole ringdown ε, lepton and neutrino textures, Blast‑Consistency Index); (ii) a human‑readable README and scoreboard image explaining how these gates map onto Kaku’s three criteria (GR intact, particle zoo, no anomalies); (iii) a ΔN_eff / Ω_gw auditor for arbitrary SBPL parameters; (iv) CSV templates and a run‑card for recomputing the PTA PCI and ringdown gates from raw data; and (v) origin‑kit notes summarising how a higher‑D “blast” could map into the SBPL parameters. In the current vNOW configuration, the SBPL spectrum is fully consistent with the common‑signal GW background seen by international PTAs, with ΔN_eff safely below current Planck and forecast CMB‑S4 limits, and with existing LVK stochastic and ringdown constraints. The electron mass is reproduced exactly via a simple higher‑D‑inspired texture, and an exploratory neutrino texture ties the lepton sector to the same small parameter \varepsilon_\ell=\sqrt{m_\mu/m_\tau} while remaining compatible with modern global‑fit values. This release is intended as a reproducible status snapshot and tool‑kit, not as a proof that the Universe must have originated from a higher‑D blast; future data and model refinements can falsify or favour this scenario.
