Programmable UBL ⊥ DHP: Along G, Across Σ, Oblique P, Ledger L, and Falsifiable Testing

Provenance and scope.This paper—“Programmable UBL ⊥ DHP: Along G, Across Σ, Oblique P, Ledger L, and Falsifiable Testing”—is the method paper. It presents the program stack (workflow, acceptance lines, schema, falsifiers) that generated, gated, and scored the cross-platform pairs. It was written before, and directly produced, the results paper “Same Fingerprint, Different Physics: Pairing Systems by Odd-Null and Sign Flip with Falsification Testing” (2025-10-01, DOI: 10.5281/zenodo.17247101). What “Programmable UBL ⊥ DHP” provides.Default acceptance lines (A1–A6), a portable data schema (G_Table), a gate-then-score pairing algorithm, and a “Similar Item Finder” operating on dimensionless invariants. Built-in falsifiers: odd-null at center, mapped sign flip U_flip (flip-only Z), monotone-to-plateau, disable-L, and a quantitative no-backflow bound. A one-page Bench-Run Card standardizes preregistration, centering, causality checks, and invariance so results are portable and audit-ready. Novelty.To the best of our knowledge (searches: arXiv, APS, Nature Portfolio, IEEE Xplore, Zenodo; accessed 2025-10-02), no prior work integrates Ratio ≈ 1 with UBL geometry, DHP handoffs with an explicit no-backflow guard, odd/even sign-flip falsifiers at the plateau center, and a portable G_Table plus pairing algorithm for cross-platform transfer. Prior art treats these pieces separately. Who benefits.Experimentalists in condensed matter, photonics, spintronics, superconducting circuits, and precision metrology who need robust plateau control, clear falsifiers, and recipe transfer across dissimilar platforms. How to use it now.(1) Fill two G_Table starter rows; (2) run the Bench-Run Card with A1–A6; (3) publish a plateau certificate (fields + pass/fail per falsifier); (4) use the Similar Item Finder to identify transfer candidates and validate with transfer tests; (5) for device-independent reporting, see the Hilbert Subspace containment pointer.
