about

nx_cadtwin_research2.nx -- FRESH 2025-2026 SOTA bank for the CAD car-twin reconstruction frontier (operator 2026-07-08: "build with the 25 and 26 research via nishi researcher, benchmark it there"). Banks the verified 2025-2026 papers the researcher agent found, so the census bars + builds are grounded in the CURRENT frontier (not 2024). KEY FINDING baked into the bars: classical COLMAP MVS = 0.532mm DTU Chamfer ~= neural VGGT on ACCURACY -> the sovereign classical path (nx_recon3d) is accuracy-competitive; neural feed-forward (VGGT/Pi3/DUSt3R) wins SPEED + sparse-view, not fidelity. The ONE checkpoint-bound bottleneck = F4 scan-> parametric-CAD (CAD-Recode LLM). Same sovereign TLS stack as nx_cadtwin_research. Saves knowledge/fetched/ ct2_*.raw. Fetch status self-verifies (200 = real; non-200 skipped + reported). expect_exit: 0 license_tier: ORIGINAL
