Two-Pass Integration Engines A Derived Architecture for Robust Transformation Systems

This paper presents Two-Pass Integration Engines (TPIE), a general-purpose system architecture for robust transformation under irreversible change. The core contribution is a hard acceptance rule: no integrated system is considered coherent unless it survives two fundamentally different integration passes, where the second pass inverts roles, dominance, and constraint direction. The paper formalizes this as a multi-phase transformation pipeline with explicit teardown, residue removal, inversion testing, and collapse handling. This architecture directly addresses common failure modes in complex modern systems, including silent dominance, one-way integration, residual coupling, and cosmetic coherence. The result is a standalone, framework-agnostic technology pattern applicable to multimodal systems, autonomous agents, safety-critical pipelines, and human–machine collaboration.
