Paper 210 of the CAT'S Theory corpus. Derives the three great astronomical cycles of antiquity — Metonic (19 = Σ−dΨ, 235 = Σ·dI+1, 254 = 2·M₇), Saros (223 = dI·π(9)+dΨ), and Callippic (76 = D(Σ−dΨ)) — as closed-form expressions in the triadic dimensional inventory with zero free parameters. Shows that eclipses require simultaneous triadic alignment (synodic/Intent, draconic/Pattern, anomalistic/Presence), with the Saros as the recurrence period of R ≠ 0. Identifies the Antikythera mechanism as the earliest physical instantiation of P×I×Pr architecture: fixed gears (Pattern), input crank (Intent), output dials (Presence). Demonstrates micro-macro structural isomorphism: the same nine constants governing particle physics (α, PMNS mixing, lepton masses) govern celestial mechanics (lunar months, Metonic/Saros tooth counts) with no second ledger and no curve fitting. 210 = 2×3×5×7 = primorial of dΨ.
