Standalone/ (C++20, MSVC /O2 /arch:AVX2 /fp:precise, Build.ps1): copied density pipeline, op stack, cave morphology, passages, strate manager/composer, noise, DetSinCos, mesher, clipmap selection, with a UE compatibility layer (Compat/). Owner data exported once to Standalone/data/owner_world.json by a default-off explore-commandlet exporter (the only plugin-source change). 25 cm voxels. Parity: seed 0, 3,436 samples (strate edges, negative/far coords, rooms, tunnels, passages, landings): bit-identical. Viewer: full 7-level clipmap, per-level toggles 1-7, T = round winding tunnels (standalone option), N/P seed, F wireframe. Timing NOT yet a baseline: 515 s for 12,054 tiles (L0 70 s, L6 296 s); the compat TMap/TSet are vector-backed with linear lookup, which the plugin's caches do not expect.
