This preprint extends the Self-Organizing Comparative-Advantage Slider Model by explaining why similar role configurations can generate substantially different relational outcomes across dyads and contexts. The paper introduces three higher-order regulatory modulators: partner-specific domain weights representing salience, contextual damping or amplification representing the resource sensitivity of the dyadic system, and perceived external alternatives as an ignition gate shaping whether accumulated strain is expressed as overt conflict or chronic friction. The framework distinguishes the structural production of strain from its subjective weighting, contextual amplification, and mode of expression. It thereby explains why high strain may remain contained as withdrawal, cynicism, or gradual erosion when escalation gates are relatively closed, while comparable strain may produce acute conflict when perceived exit viability lowers ignition thresholds. The paper derives hypotheses H9–H13 and outlines measurement strategies for cross-sectional, longitudinal, experimental, and intensive longitudinal designs, including APIM, EMA, and DSEM approaches. Salience mapping, contextual buffering, and ignition-gate manipulations are presented as research analogues rather than clinical protocols or treatment recommendations. This contribution is intended for researchers in relationship science, social psychology, behavioural regulation, and complex relational systems. Mathematics in the Dyadic Systems Series is representational rather than foundational. Formal notation is used to make proposed mechanisms, constraints, dependencies, and directional tendencies explicit, internally consistent, and empirically addressable. The equations are neither exhaustive descriptions of lived relational dynamics nor claims that dyads perform numerical optimisation. The theoretical contribution resides in the identified system mechanics; formalisation provides a disciplined language through which those mechanics can be communicated, examined, and tested.
