Re-quantifying the Calderón--Zygmund pressure estimate for Theorem A #

The established transfer pressureP1_thetaDecay_hCZ_of_global_slice turns one almost-every-time slice certificate for the centred first pressure potential of the decomposition prop:pressure-decomposition into the r-scaled extended-real Calderón--Zygmund estimate ext:CZ on the concentric parabolic sub-cylinder. The small-data statement thm:A consumes that estimate quantified over all suitable weak solutions at a fixed force exponent q, so the slice hypothesis must itself be uniform in the solution.

This file provides the single re-quantification adapter: from a slice certificate available for every suitable weak solution, it produces the solution-uniform ext:CZ estimate with the exact binder consumed downstream.

Re-quantify the singly-centred slice certificate of prop:pressure-decomposition over all suitable weak solutions, yielding the solution-uniform r-scaled extended-real Calderón--Zygmund estimate ext:CZ on the concentric parabolic sub-cylinder.
