QDL Experimental Validation Protocol: A Unified Roadmap for Torsion, NV-Center, Cavity, and Metamaterial Tests

This technical report defines the first complete experimental validation framework for the Quantized Dimensional Ledger (QDL), a dimensional-closure system that expresses all physical quantities using only three base units: action (A), length (L), and frequency (F). Building on prior QDL work in metrology, electromagnetism, gravitation, and toroidal-coordinate structure, the protocol specifies four complementary tabletop experiments designed as falsifiable tests of QDL:(1) a torsion-balance torque scaling test,(2) a nitrogen-vacancy (NV) center frequency-shift scaling test,(3) a cavity inverse-length resonator test, and(4) a metamaterial scaling-collapse test. For each experiment, the report derives ledger-based scaling laws, defines equal-parameter comparison rules against standard SI-based models, and sets out preregistration, dataset-locking, blinding, and reproducibility requirements. Explicit falsification criteria are given for each domain, along with a unified statistical framework based on AIC, cross-validated R2R^2R2, bootstrap confidence intervals, and residual analysis. These experiments collectively define Phase 0 through Phase 1 of the Eagle Initiative: a staged program to move QDL from a purely theoretical construction to a rigorously testable physical framework. The document is intended as a citable, open protocol for independent laboratories interested in evaluating QDL under modern open-science standards.
