/**
 * metatron-logic.mjs — METATRON Recursive Logic Engine
 *
 * The METATRON backward read applied to each sorry in the Lean files.
 * Uses Ahmad's ERE (5-pass Enochian Reading Engine) + entropy gate.
 *
 * For each sorry:
 *   Forward read  (Reasoning):  what does the theorem claim?
 *   Backward read (METATRON):   what must be true for that claim to hold?
 *   ERE:                         is the backward read fabrication-free?
 *   Entropy gate:                is the proof path below H_φ < 0.21?
 *   Classification:              PROVABLE | GENUINELY_OPEN | FALSE_AS_STATED
 *
 * Output: Lean proof terms for PROVABLE cases.
