One axiom. One operation. Zero free parameters. The Standard Model carries roughly two dozen free parameters — lepton and quark masses, neutrino splittings, mixing angles, the CP phase — plus the cosmological constants. Every one is measured and inserted by hand; none is derived. This paper derives them. From the same axiom (the One) and operation (the fold) that fix the fine-structure constant, the charged leptons are the three roots of one cubic x³ − x² + (1/6)x − 1/485 = 0 whose roots sum to the One and whose squares give the measured mass ratios; the Koide relation falls out as exactly 2/3. The quark ratios follow by a single forward dressing over the forced 1/α. The neutrino is single-handed, so a Dirac mass is forbidden and a Majorana mass is forced — neutrinoless double-beta decay must occur — with mass-squared ratio fixed at 3/100. CKM mixing is the bare overlap of two fold bases; the CP phase sits at the unique self-antipodal point, the half-One, giving maximal CP violation (Jarlskog ≈ 3.1×10⁻⁵). In cosmology: dark-to-baryon 27/5, a positive non-zero cosmological constant at the binary floor 2⁻²⁰ (the 10¹²⁰ catastrophe dissolved), the Hubble calibration ratio 13/12, and the black-hole quarter 1/4. No measured value enters any construction; every result is machine-checked and reproduces from one command.
