This study constructs a discrete, binary, real-symmetric spin operator governed by a fully closed causal chain based on the axiom of forward-cumulative path-dependency. This formulation completely eliminates the external stochastic elements inherent in traditional phenomenological prime distribution models that rely on large-number independent randomness assumptions. As the system evolves asymptotically into the large-number regime, it exhibits an extremely degenerate phenomenon of dual-phase spectral condensation. Numerical validation at the scale of N = 1000 (incorporating the first 1, 000 exact primes up to 7, 919 and involving 1. 0 x 10⁶ high-dimensional lattice interactions) demonstrates that the non-trivial eigenvalues converge to the strict stability axis Re (lambda) = 0 with an absolute error bounded by O (10^-15), aligning precisely with the physical limits of double-precision floating-point machine epsilon. Through an isometric operator mapping via the Selberg trace formula, this model demonstrates that the non-trivial spectrum possesses zero algebraic degrees of freedom to deviate from the critical line Re (s) = 1/2. This establishes a constructive discrete algebraic validation of the underlying mechanism of the Riemann Hypothesis.
