Pre-Integrative Exclusion and Causal Relayability: Structural Asymmetry in State Space

This record is a separate and orthogonal companion work. It does not belong to, derive from, or extend the TII Framework. It asks which candidate trajectories fail to enter causal history before integration, selection, learning, or strategic interaction begin. Its central criterion is causal relayability: a trajectory that cannot relay the constraints imposed by its prior states into future transitions cannot enter causal history. The paper does not provide a generative mechanism, predictive model, or normative doctrine. Nor does it explain phenotype-specific biological traits or downstream evolutionary stabilization. What it secures, if anything, is a pre-integrative structural perspective on state-space asymmetry, pruning, exclusion, and causal relayability prior to integration.
