Operational Quantum Gravity from Standard-Model Stress Response: Static Matching, Causal Tensor Dynamics, and Einstein-Equivalent Gravity
The complete interacting Standard Model is treated as the microscopic source of a causal tensor response whose long-wavelength representation is Einstein-equivalent gravity.

Question
Can known quantum matter generate the constitutive stiffness, causal compliance, and massless spin-two structure needed for macroscopic gravity without making geometry fundamental?
Approach
Construct the closed-time-path stress Hessian of the conserved Standard Model, include Ward-required contacts, match the static TT sector through second order in the couplings, continue the retarded spectrum, and represent its infrared branch with fixed-measure WTDiff.
Main result
The calculation closes perturbatively into one finite matter-generated stiffness. Its causal response contains a massless long-range branch, an underdamped resonance, and separate pair-production and scattering continua. The minimal local WTDiff completion is Einstein-equivalent.
Boundary
The renormalized Higgs-curvature coupling and two finite three-dimensional Yang-Mills responses remain identifiable Standard-Model inputs. The reference-state intercept and the higher connected stress hierarchy remain separate closure calculations.
