We present a complete survey of intersecting D6-brane Pati--Salam models, where systematic Diophantine solving reduces billions of compactifications to 65 physically distinct vacua across three complementary constructions. This yields a concrete realization of the "one in a billion" paradigm for MSSM-like D-brane statistics. String-scale gauge coupling unification is achieved in all classes via vector-like particles and two-loop RGE evolution.
