Physical scale from a coupled mixing witness #

This module restores the microscopic source, combines it with the selected mixing scale, and proves the strict two-part tail and physical all-later row estimate. The mixing tail and bad-event certificate are consumed from one coupled witness.

theorem HCPolySupport.HighContrast.Quenched.exists_coupled_physical_outer_constants (cMix Crebase Cann Cmix : ℝ) :
∃ (C : ℝ) (cSrc : ℝ), 1 < C ∧ 1 < cSrc ∧ cMix ≤ C ∧ cSrc < C ∧ Crebase ≤ C ∧ Cann + Cmix ≤ C

Deterministic outer constants can simultaneously absorb the rebase cost, the annealed and mixing length exponents, and the two strict tail thresholds.
