The Emergent Condensate Superfluid Medium framework (ECSM) proposes that gravitational, inertial, optical and relativistic phenomena arise from finite-response dynamics of an underlying coherent medium rather than from physical spacetime curvature. This paper presents a non-geometric formulation of the ECSM gravity sector from first principles. The parent variables are medium density, phase, coherence, constitutive response, internal orientation, transport and stress variables. No physical metric, curvature action, geodesic equation, metric horizon or singularity is introduced as a primitive mechanism. The construction proceeds through linked sectors. Inertia and static gravitational response are generated from one matter-medium coupling. Clock-rate shifts arise from local reconfiguration burden. Light bending arises from optical dispersion gradients and coherence gradients. Lorentz contraction is treated as contraction of the moving matter-response pattern, not contraction of space. Rotational response is described through vorticity and anisotropic stress. Compact-object behaviour is described through finite saturation, transport trapping, shell stress modes and medium tidal susceptibility. Galaxy dynamics and lensing are generated from one constitutive response kernel with explicit domain-boundary gradients. Cosmological propagation is represented by a frequency-dependent response kernel with acoustic-like, damping-like and boundary-transfer structure. Across the supporting executed public notebook chain (NG1R-NG5R, NG5R-v2, and NG7R-NG10R), the NG10R audit reports 340/340 prior-stage tests passed, all ontology audits passed, and the combined forbidden-geometry primitive count was zero. The NG6R identifier was not assigned to a standalone public notebook in this chain; the rotational-response sector is included analytically in the manuscript.
