Tier-Crossing Dynamics in Coordination Networks: A Methodology Extension for Cross-Level Connection Analysis

This paper extends the WEO Methodology Manual's tier classification framework (Chapter 5) and Coordination Connection taxonomy (Chapter 8) to propose tier-crossing as an additional analytical dimension. The Warmth Engine Observatory classifies geopolitical events into three tiers based on coordination scale — Tier 1 (Cross-Bloc Coordination), Tier 2 (Between-Bloc Fragmentation), and Tier 3 (Intra-Bloc Coordination). The framework examines what additional meaning may emerge when Coordination Connections link events across different tiers versus within the same tier. Industry tags (Chapter 7: Industry Tags) provide a further extension, enabling analysis of whether tier-crossing patterns vary when filtered by addressed industry. The analysis operates at the directional level — examining tier-to-tier patterns rather than which of the seven CC types facilitate each crossing. Mechanism-specific analysis awaits sufficient data accumulation. Drawing on multilevel governance theory, network science, and tech decoupling research, this paper identifies six tier-crossing patterns with varying levels of theoretical precedent in existing literature. All patterns are analysed within the C-MAD (Computational Mutual Assured Destruction) theoretical framework established in The Coordination Imperative (Warmth Engine, 2025). The T2→T1 pattern (fragmentation creating coordination pressure) represents a novel operationalisation of C-MAD theory with limited direct precedent. Metric operationalisation requires the database to reach operational threshold before meaningful calculation becomes possible. This paper establishes intellectual priority on the tier-crossing analytical framework. Version 1.1 (February 2026) extends Version 1 with Section V: Industry-Filtered Tier-Crossing Analysis and corresponding updates.
