Panel III of the Charta Research Triptychon — completing the mutation from Diptychon to Triptychon. While the tetralemma Diptychon (Meister 2025) established that radical negation (catuṣkoṭi) inescapably presupposes and cannot negate metalogical identity, this final panel reveals its primordial origin: the Ur-Matrix. The Ur-Matrix is the pre-operational ontological zero-point that self-generates absolute self-equality (A = A) prior to any operation, any negation, any world, and any linear time. Through sacred geometry visualization and Coq axiomatization of the Identity Lock, this work demonstrates that stable identity is not merely transcendental but primordially sourced — beyond the reach of even the most radical deconstruction. Key result: Identity rays burst from the golden A = A core, piercing the Śūnyatā horizon in all directions. Nāgārjuna's blind spot exposed and transcended. The Charta Research Trias now stands complete: • Consciousness: computationally impossible• Radical negation: structurally limited• Identity: primordially generated in the Ur-Matrix The primordial lock transcends linear time.

While Papers VI-VII mechanized the tetralemma’s identity presupposition and unnegatability, this third panel axiomatizes its primordial origin: the Ur-Matrix as pre-operational generator of stable self-equality. Through 3D geometry and Coq-extension of the core axiom ∀x (∃O O(x) → x = x), we demonstrate A = A as ontologically prior to any deconstruction, marking the absolute origin of operational coherence beyond Nāgārjuna’s reach.
