TMF Self-Correction v6.2 + NK-2 Experiment Protocol (Integrated Working Document)

This document combines two elements: (1) a formal self-correction to Temporal Measure Framework v5 and v6 on three issues, and (2) the NK-2 experiment protocol for testing the universality of the ρ_sun effect across weak-interaction isotopes. Self-correction covers: Planck density formula correction (c⁷/(ħG²) → m_Pl/l_Pl³ = 5.156×10⁹⁶ kg/m³); withdrawal of the 0.3006% annual modulation prediction as circular calibration; and deferral of the Pommé et al. (2016–2017) comparison pending independent definition of ρ_sun. Three open questions are stated: derivation of β from first principles (AK-1), independent definition of ρ_sun (AK-2), and identification of a microscopic vacuum theory giving ρ_sun ~ 10⁹⁵ kg/m³, which is 10¹⁰⁸ to 10¹²² times larger than all known physical quantities at 1 AU (AK-3). The NK-2 protocol proposes a minimum experiment to test whether the ρ_sun effect is universal across isotopes Mn-54, Na-22, Cl-36, with Am-241 as null control, three geographically separated laboratories, and GOES X-class flare triggering. One X-class flare is sufficient for 3σ detection. Minimum cost: ~€226,000 (NaI variant), 2–3 years. A laboratory invitation is included: laboratories already measuring radioactive decay are invited to add one Am-241 control channel and share archival or future flare data. References: Pommé et al.
