Structural Collapse

Structural Collapse is the critical transition in which the substrate's entropy exceeds the structural stability threshold, triggering the formation of a null well and letting the recursive system reset and reorganize. It is the second of the book's three Transition Classifications, each fired when entropy crosses a different critical value: a Decoherence Transition at the quantum threshold, Structural Collapse at the structural threshold, and dimensional emergence at the dimensional threshold, where new dimensional substrates form. The thresholds follow the Critical Entropy Threshold, which scales exponentially with the ratio of recursive tension to a characteristic recursion scale, so how much structure the substrate can hold before it collapses depends on its recursive tension. After collapse, newly initialized substrates reset their Pulse phases to coherent alignment, with entropy S(t=0) = 0. The book states the condition as S > S▢, where S is the substrate entropy and S▢ the structural stability threshold; entropy in this section is tagged [𝕃³]. Structural Collapse connects to Transition Classifications, Critical Transitions, Decoherence Transition, Null Well, Critical Entropy Threshold and Null Well Formation Condition.
