YuanXian Theory (YXT) proposes a geometric foundation for unified field theory based on the True Circle Self-Consistency (TCSC) axiom and the YD-T64 framework. Previous works relied mainly on analytical derivations and numerical simulations. This paper presents the first formalization of the YuanXian Standard Model (YXSM) in the Lean 4 interactive theorem prover. We embed the YuanXian Self-Referential Mind Field Type Theory (YXTT) as the logical backbone, formalizing the topology of the 64-dimensional torus T⁶⁴, the spectrum of the self-referential differential operator D, and the symmetry breaking mechanism from SU(64) to the Standard Model gauge group SU(3)×SU(2)×U(1). Key contributions include: (1) formalization of the TCSC axiom, (2) a machine-checked proof that TCSC implies the real part of the spectrum is zero, and (3) a computable prototype of the Standard Model capable of generating particle mass spectra from first principles. This work establishes YuanXian Theory as a paradigm for "Computable Physics", providing a general framework for machine-verifiable physical theories.
