Navel–Tetra Lattice-Occupancy Model: Nucleon, Electron and Higgs Mass Ratios from a Geometric Lattice, with an Outlook on Dark Matter and Black Holes / へそとテトラの格子占有モデル

A phenomenological lattice-occupancy model (bilingual English/Japanese). A population tripling each generation (2·3n) first overflows a cubic lattice at 53 = 125 (162 vs 125, overflow 37 = 43 − 33). With a compression factor 501/500 and a staging rule, the nucleon, proton, neutron and helium-4 masses relative to the electron are reproduced to +0.0007% (CODATA 2022). The free-neutron decay Q-value equals 5/3 in nucleon units to 0.06%. A separate counting gives mH/me = 245000, a falsifiable Higgs-mass prediction of 125.1947 GeV (PDG 2025: 125.20 ± 0.11 GeV). All fitted choices are listed explicitly. The note closes with research questions and quantitative targets for dark energy, dark matter and black holes. Includes a Python verification script (47 assertions). 格子占有に基づく現象論的モデル(日英併記)。核子・陽子・中性子・ヘリウム4の電子との質量比を +0.0007% で再現し、ヒッグス質量 125.1947 GeV を反証可能な予測として示す。選択した仮定はすべて明記し、ダークエネルギー・ダークマター・ブラックホールへの研究課題を数値目標とともに挙げる。検算スクリプト付き。
