Semantic Fibers and Cross-Gram Interference: A Calculus of Safety Drift in Overcomplete Representations
An intrinsic calibrated exposure measure is introduced, governed by the leverage duality $\chi^2=1/\ell-1$, which separates observed drift into three diagnostically distinct regimes: a reader fault removable by recalibration, an exact correction that is too ill-conditioned to be reliable, and a representation-level col...
