The declaration moon_resonance_pq appears in module IndisputableMonolith.Astrophysics.TidalLockingFromPhiResonance inside a noncomputable section.
(1) In plain English it is a constant that sets the Moon-Earth spin-orbit resonance ratio to exactly 1 (one rotation per orbit, i.e., synchronous tidal locking).
(2) In Recognition Science it supplies the baseline trivial resonance whose J-cost is zero; the surrounding theorems then locate the Mercury 3:2 and Venus 4:1 ratios inside the canonical J(φ) band, showing that observed Solar-System resonances occupy φ-rational positions on the recognition lattice.
(3) The formal statement is simply def moon_resonance_pq : ℝ := 1. It is a non-computable definition of type ℝ whose value is the literal numeral 1; no computation or proof obligation is attached to the definition itself.
(4) Visible dependencies and certificates: the module imports IndisputableMonolith.Constants and IndisputableMonolith.Cost. The definition is immediately used by moon_resonance_eq (proved by rfl) and moon_J_cost_zero (proved via Cost.Jcost_unit0). It is also referenced inside the master certificate tidalLockingFromPhiResonanceCert and the one-statement summary tidal_locking_one_statement.
(5) The declaration itself does not prove the physical mechanism that produces the 1:1 lock, does not derive the integer 1 from the forcing chain or from J-cost minimisation, and does not address stability or tidal-evolution dynamics; those remain outside the supplied module.
