TDVT Acoustic Bubble Drive (TABD): analogue warp architecture and locked numerics

Engineering compilation of the TDVT Acoustic Bubble Drive (TABD), a controllable analogue warp architecture obtained by reworking the earlier THA-WD blueprint under the locked claim structure of Quantum Vacuum Catalyzation (QVC) and teleparallel hopfion spacetime (TDVT). The working medium is a hopfion–superfluid metamaterial whose collective excitations obey an Unruh–Visser acoustic metric. An Alcubierre shape function on the background superfluid velocity produces a sonic bubble that can exceed ambient sound speed (Mach number M = v_b/c_s) while remaining locally causal on the effective metric. Claim layers. L1: microscopic TEVC cell (near-term, falsifiable). L2: mesoscopic acoustic Alcubierre bubble. L3: real-spacetime GR warp / NEC violation — open, not claimed. Vacuum is treated as a catalyst, not an energy source. Laboratory Einstein equivalence is not claimed. This deposit includes the August 2026 engineering overview (TeX and PDF), locked numerics, Python drive compute, and an interactive analogue-gravity HUD.
