Episode Two moves from fracture to structure — the moment a system begins to see the architecture beneath behavior. This episode introduces the second principle of Behavioral Architecture: compatibility. Environments are not neutral; they either fit the people inside them or force them into compensation. When compatibility breaks, systems generate friction, effort spikes, and people begin carrying loads the environment was supposed to hold. This is the architecture behind fit, mismatch, escalation, and the early signals that an environment is no longer aligned with its demands.
