The Policy Distortion Factor Phi: Decomposing Routing Efficiency in Delay-Tolerant Networks

V5.0 (March 2026): Revised terminology and epistemic framing throughout. Definitional identities relabeled as Propositions. Classification language updated. Mechanism descriptions qualified as proposed interpretations. License updated to AGPL-3.0-or-later. Scientific conclusions unchanged. v4.0 (March 2026): Revised for consistency with classification theorem v7.0. Demoted empirical results from Theorem to Observation/Conjecture. Corrected gamma normalization convention. Updated DOI cross-references to concept DOIs. Added self-DOI to author block. Qualitative conclusions unchanged. The realized delivery ratio of a delay-tolerant network factors exactly into three components: temporal reachability ST, a…
