The standard CPT theorem asserts that any local, Lorentz-invariant, unitary quantum field theory remains invariant under the combined action of charge conjugation, parity inversion, and time reversal. This theorem is among the most stable invariance principles in modern physics. Yet its conventional formulation remains primarily formal: it specifies the conditions under which CPT invariance must hold, but does not fully explain why this particular composite symmetry occupies such a privileged position in physical law. This paper reformulates CPT invariance as a coherence-restoration principle grounded in the Universal Field Tensor. Rather than treating C, P, and T as merely geometric or algebraic transformations within spacetime, they are interpreted as reduced projections of deeper coherence operations: coherence-polarity inversion, projection-orientation inversion, and temporal-phase inversion. CPT is then understood as the unique composite operation that restores the full coherence structure after any partial reduction, projection, or symmetry-disclosing event. Under this interpretation, CP violation, neutrino chirality, matter-antimatter asymmetry, and entanglement are approached as signs of partial or asymmetric coherence disclosure rather than failures of deeper invariance. Standard CPT is preserved as the geometric limiting case of a deeper coherence law. The central thesis is that CPT is not merely a spacetime theorem, but the spacetime shadow of total coherence restoration. Plain-Language Preface Modern physics teaches that the combined operation of charge reversal, mirror reversal, and time reversal must preserve the fundamental laws of nature. This is called CPT symmetry. Even when individual symmetries appear broken, the combined CPT relation remains protected. But this raises a deeper question: why should this particular threefold operation be so fundamental? This paper proposes that CPT is not merely a rule inside spacetime. It is the visible expression of a deeper coherence law. Reality may disclose partial asymmetries - such as CP violation, chirality bias, time direction, or matter dominance - but it cannot lose the underlying coherence structure from which lawful appearance emerges. In this interpretation, C reverses coherence polarity, P reverses projection orientation, and T reverses temporal phase-order. Taken separately, these operations may reveal asymmetry. Taken together, they restore the full coherence relation. CPT therefore becomes more than a formal theorem. It becomes a signature of reality preserving coherence beneath all projected appearances.
