States how relativity, in both forms, is recovered from the finite-QEC substrate. Special relativity is the universal reversible propagation clock: the invariant speed c is one lattice step per service tick, and observers built from the same walk/QEC clock infer Lorentz symmetry despite a preferred update order (1D walk theorem; an exactly isotropic massless Weyl cone H2 = (Σ sin2kd)I from an anticommuting chirality Clifford triple; no bare Dirac mass). General relativity is the coarse-grained covariance of that clock under strain: straining the cone gives the metric directly, gij = δij + 2εij, so the metric perturbation IS the strain field; the matter strain-response is a conserved symmetric stress tensor; the linearised Bianchi identity and the substrate's strain-ledger conservation are one statement, making G = 8πG T a consistent field equation. The equivalence principle follows once gravity couples to the full energy (kinetic plus confinement/Yukawa mass), not the bare hopping (which would be anti-mass); and the four horizon objects (area law, Hawking ladder, firewall isometry, gravitational source) are one register syndrome read four ways. Tiers are explicit: the kinematic spine is computed and machine-verified; the Nielsen-Ninomiya, Sakharov, and Weinberg steps are flagged imports. Copyright (C) 2026 D. G. Elliman.
