Empirical Test Plan for PIF-1.0 (Planck Information Framework)

This document presents the complete empirical test plan for the Planck Information Framework 1.0 (PIF-1.0). It outlines a seven-level validation strategy—from numerical simulation and tabletop optics to analogue horizons (optical fibre, BEC), cavity-QED systems, multi-sensor field experiments, and astrophysical/cosmological data analysis—designed to test PIF-1.0’s core relations: - I_p(total) = I_p(internal) + I_p(projected) (information conservation), - S_proj = f_total × S_max with S_max proportional to area A (holographic ceiling), - ΔE ≈ T_eff × S_max × Δf_total (energy–entropy–information coupling), - Δt ≥ t_p (temporal discretization as a Planck-time filter). The plan provides concrete protocols for measuring the projection factor f via entropy (f_S), compression (f_K), and mutual information (f_MI), and includes realistic simulations (e.g., optical microcavity with S_max ≈ 1.37×10⁴⁴ J/K). It culminates in a cross-scale meta-analysis (Level 6) to verify that the same functional form holds from photons to the cosmos. This test plan is the empirical counterpart to the theoretical framework PIF-1.0 (DOI: 10.5281/zenodo.17296182).
