Sharp Gaussian information-response frontiers: finite p-adic realization and noncommuting harmonic quenches

How strongly can a positive precision update change a Gaussian response at a given information cost? Standard log-determinant and inverse-update identities do not by themselves determine the admissible costs when the worst modal contraction, total contraction, and active-rank cap are fixed. On a finite-dimensional phys...
