Temporal Delay Under Spatial Accessibility Restriction in a Native SU(2) Substrate

Gravitype V8.0 — Experiment This record contains the paper “Temporal Delay Under Spatial Accessibility Restriction in a Native SU(2) Substrate” together with its reproducibility context. V8.0 is an experimental Gravitype release. It tests whether restricting the spatial accessibility of reconciliation updates, while leaving the substrate and update schedule unchanged, produces a deterministic temporal delay in relaxation. The paired observable is the threshold-crossing delay Δτ_50(s) = τ_50(RESTRICTED) − τ_50(NATIVE) with τ_50 defined as the first timestep at which total frustration falls below a fixed fractional threshold. Across 200 paired realizations at ρ = 0.1, the delay is strictly positive for all seeds, with median Δτ_50 = 2, min = 1, max = 4, W = 20100, and p = 4.64 × 10^-37 (one-sided). Deterministic replay yields zero mismatches, placebo controls are null, and mask enforcement is stable under a fixed BARRIER configuration. This release is the temporal complement to V7.0: where V7.0 establishes accessibility-defined regime divergence, V8.0 establishes a direct temporal consequence under a locked native-substrate protocol. It serves as an empirical bridge to later interpretive work on relaxation-based time.
