Bloc-Conditional Event States: Measuring Cross-Coverage Divergence for Threat-Intelligence Analysis

Maryam Fooladi, Federico Bottino


Abstract
We propose a content-level measurement of cross-bloc framing divergence in news coverage of contested events, built on the eventstate (ρe) formalism of Bottino et al. (2026). For a given event, outlets are aggregated into editorially-coherent blocs and each bloc is represented by a density matrix ρ bloc on a 15-dimensional framing space. The trace distance D(ρ state, ρmainstream) measures cross-bloc divergence; benchmarking it against the withinWestern polarization D(ρ right, ρleft) controls for editorial variation. The top eigenvector of (ρ state − ρ mainstream) attributes divergence to specific framing axes. Two case studies (Hormuz blockade 2026, n = 16; Navalny death 2024, n = 14) demonstrate the construction. The work positions D(ρ state, ρmainstream) as a content-level observable of potential interest to threat-intelligence workflows that currently rely on source-level features.
