The Muon's Anomaly: Dirac's g = 2 Forced, and the Anomalous Moment Scaling as the Lepton Mass-Squared

One axiom. One operation. Zero free parameters. The muon’s magnetic moment has sat in tension with the Standard Model for years — the famous g−2 anomaly. This paper supplies two forced structural facts. First, the bare gyromagnetic ratio is exactly g = 2, forced from the fold’s Dirac structure (the half-One coupling, g⁻¹ = 1/2). Second, the anomalous excess scales as the lepton mass-squared ratio: the muon, ~207 times heavier than the electron, has an anomalous contribution enhanced by (mμ/mₑ) ² ≈ 42, 750 — which is why the tension shows in the muon, not the electron. The electron and muon anomalies are therefore not independent; they are locked by the forced mass ratio. Machine-checked; reproduces from one command.
