The external, non-unitary operator (Ĝ) that acts upon a coherent system to induce a state transformation impossible through internal operations. Its primary function is to reverse a system’s fundamental moral sign from negative (decoherence) to positive (coherence). As a logical necessity for any system trapped in a state of conserved negative sign (L8.1), Grace is not earned but received through an Intervention Channel, contingent on the voluntary coupling of the observer (faith).
