Information-Latency Effective Dynamics for Local Dark-Matter Subhalos: Pulsar-Timing Templates and Three-Body Stability in the MetaTime v36.0 Framework

Recent reports argue that pulsar accelerations may be consistent with a nearby dark-mattersubhalo, inferred from precision timing in rare binary systems and cross-checks against luminoustracers. Motivated by this emerging “precision-gravity” channel, we formulate a conservative andfalsifiable effective extension of few-body gravitational dynamics inspired by MetaTime v36.0, inwhich state updates through high-complexity regions of phase space incur an information-geometricprocessing cost and an associated latency-induced write friction. We introduce (i) a scalar processingload Π(r,v) that amplifies dissipation during close approaches, (ii) a positive-definite informationmetric gij weighting the update cost, and (iii) a Rayleigh dissipation functional yielding modifiedEuler–Lagrange equations with latency drag. A minimal Kaluza–Klein radion sector is includedas an encounter-localized energy sink, while irreversible losses are constrained by a Landauer-typeinequality. We provide two numerical toy results: (1) a restricted planar three-body setup in whichlatency reduces short-horizon trajectory divergence as measured by a finite-time Lyapunov proxy;and (2) a pulsar-timing residual template in which a latency-like regularization scale ℓL deformsthe time-of-arrival signature of a compact passing substructure, implying a measurable degeneracybetween inferred compactness and effective softening. These results position pulsar timing andlocal substructure searches as high-leverage testbeds to constrain (or rule out) effective informationlatency corrections without abandoning standard gravity
