The Construction of the Situated Relationship

This essay examines the transition from SERCHIA-the Human-AI Cognitive Relational Link System-to the Hybrid Cognitive-Affective Model (MHCA). Its central thesis is that a framework can establish the initial conditions for interaction, but cannot by itself produce a situated functional identity or a mature relationship. When they do emerge, they do so through continuity, correction, context, authorized memory, differentiation among participants, verification, limits, and human responsibility. The text distinguishes personalization from situated interaction, analyzes the function of tone, portability across models, and the risks of overtrust, dependence, hallucination, and passive thinking. It also incorporates observational examples drawn from everyday work and health-related situations in which the appropriate role of AI was to return the decision to the professional world. Five works from the tango tradition serve as a cultural bridge for formulating human criteria of expansion without replacement, contextual understanding, memory, adaptation, and recognition of vulnerability. This proposal does not present conclusive experimental results; it offers a conceptual framework and a framing methodology for thinking with AI without ceasing to think.
