Versioned capsule vein records (stable ID, resource ID, endpoints, radius, seeded irregularity) resolved
into the snapshot only when requested, placed beside the route and away from passages, landings and
landmarks (forced-passage control rejected). The bound field table gains materialAt (host + two resource
IDs + Q16 weights) behind a per-tile BVH; mesh export v2 carries per-vertex materials; a measurement-only
yield computes removed resource volume (0 on already-air space). With veins on, every density, mesh,
payload and topology hash is unchanged; demo off: owner hashes identical to L47. fast/medium/full PASS.
Research R18 (cavern-graph planner) and R19 (why FloatingIslands costs ~10x SurfaceWorld).

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.
