Local finite-p coarse-graining assembly #

This is the source-facing assembly point for the frozen local finite-p coarse-graining theorem. The reusable input modules deliberately keep the negative-series expansion, descendant restriction, response localization, and forcing summation separate; this file only combines those literal carriers.

The exact local finite-p coarse-graining theorem frozen in the Chapter 3 declaration anchors. All regularity, trace, response, and summability work is discharged internally through the one-cube and forcing seams.
