V.T18 — Hubble Tension Resolution
The "early universe" H_0 (CMB/Planck) and "late universe" H_0 (SH0ES distance ladder) are readouts of the expansion rate at different orbit-depth regimes. The Hubble tension arises from assuming H_0 is a single number independent of measurement method; the tau-framework resolves it via regime-dependent readout.
