Ask Prometheusa parameter whose window is narrower than alternatives, such that no other value allows the thing to persist
Necessity (noun) means: a parameter whose window is narrower than alternatives, such that no other value allows the thing to persist. It emerges from parameter, window, narrow, persist: The parameter's range is constrained so tightly that only specific values permit persistence, distinguishing it from broader alternatives. In the EmergenceLexicon it sits at computed level 18, chaining down to the four foundations (space, time, energy, pattern).
