A single complex recognition field Φ coupled non-minimally to curvature provides one Lagrangian density that reproduces three pillars of fundamental physics. (1) The Einstein-Hilbert term emerges from a ξΘ[Φ] R interaction once the vacuum value of the functional Θ[Φ] = Φ†Φ/λ4rec is inserted, fixing Newton's constant through the previously established causal-diamond identity ℏG= πc3λ2rec/ln 2. (2) With Φ in the representation (3,2)1/6 a single gauge coupling at the recognition scale λ−1rec ≃2.7 ×1022 GeV flows to the observed Standard-Model couplings at MZ within one per cent—no grand-unification multiplet or extra dial is needed. (3) Integrating out recognition-regulated gravitons produces white curvature noise whose Lindblad term localizes macroscopic superpositions; the predicted collapse time for a 107-amu interferometer is 70 ns, three orders of magnitude inside forthcoming experimental reach. Two-loop renormalization of the unified theory tightens the running of G to G(r) = Grec(λrec/r)βRS with βRS =−7/(32π2) ±3.4 ×10−4, yielding a parameter-free laboratory value Glab = 6.84(10) ×10−11 m3 kg−1 s−2—a 1.6σ shift from CODATA-2022 and decisively testable by sub-micron force probes. The Lagrangian introduces no new symmetries, no extra dimensions, and no adjustable collapse constant: every numerical prediction descends from the golden-ratio stationary scale q∗= φ/π. Ghost, anomaly, and Coleman–Weinberg checks confirm perturbative consistency up to the Planck scale, positioning this blueprint as a falsifiable, all-in-one candidate for unifying gravity, gauge dynamics, and objective quantum collapse.
