DESCRIPTION This work presents a fully reproducible, audit-grade protocol for testing Superluminal Localization Theory (SLT) within the pulsar timing domain. SLT is a pre-formal physical theory proposing a two-layer causal ontology in which observable relativistic dynamics arise as a projection from a deeper localization substrate, leading to empirically testable constraints on correlation persistence and model absorbability. The paper applies an ensemble-baseline residual analysis to precision pulsar timing data, evaluating whether timing residuals remain statistically and systematically non-absorbable after subtraction of a comprehensive ensemble of standard pulsar timing models, including uncertainties from ephemerides, dispersion-measure modeling, stochastic noise processes, and time-standard realizations. The protocol is explicitly falsification-oriented and agnostic to outcome. A null result constrains SLT within the tested regime, while a robust residual outcome constitutes only a necessary condition for continued admissibility of the theory, not confirmation. No claims are made regarding superluminal signaling, violations of General Relativity, or displacement of established pulsar timing physics. This publication constitutes the third empirical pillar of a broader multi-domain research program, alongside collider-domain jet angular correlation residual tests and Bell-type correlation decay analyses, designed to assess the empirical survivability of SLT across causally and physically independent measurement regimes.
