DCRP-02: Cross-Scale Interaction Graph and Supply-Migration Rigidity

Building on DCRP-01's source-migration theorem, represents the migrated nonlinear supply as a directed interaction graph among carrier-lattice points, and proves a partner-degree compensation theorem — for fixed output, if the atomic proportion vanishes then the sub-weighted partner degree must diverge. Also proves that under comparable shell offsets, Biot–Savart quasi-locality gives bounded graph degree, so a diffuse carrier likewise cannot sustain order-fixed supply through bounded cross-scale stretching alone. Further proves a comparable-annulus recovery theorem and a conditional commutator coherence theorem.
