This document establishes the constitutional ontology of gravitation within the Energy-Efficiency Theory (EET) framework. Gravitation is defined not as a fundamental force but as the long-range gradient of the total constrained potential U (r) across the constraint network, modulated by the cooperative capacity (): F = - (U/). This is the authoritative force expression (Motion \ (ii) effective gravitational coupling established as an exact algebraic identity G₄₅₅ () = GN () = GN/ (1 + r₃₄₂ () ), structurally parallel to the gauge coupling's () 1/r₃₄₂ () (Field v3. 0) ; (iii) the -gradient force constitutionally anchored as the gravitational expression of the Third Arrow of Time (CD v3. 1) ; (iv) Jeans instability identified as the gravitational Capture Window and protostellar ignition as the gravitational Life/Non-Life Inequality (CD v3. 1) ; (v) the Ben-Se master equation mapped onto the Friedmann acceleration equation; (vi) the -generalized FDT applied to gravitational wave damping; and (vii) nine new companion ontology interfaces established, bringing the total to 25 interfaces across 22 companion ontologies. Gravitation emerges as the macroscopic signature of the constraint network's total structural content --- the gravitational memory of cosmic structure formation, carried by the irreversible accumulation of C (t) = E₁, ₈^melt and expressed through the -gradient force. Every constraint that has ever existed contributes a permanent, irreversible gravitational signature.
