- GET /api/splat serves data/work/splat.ply; manifest reports has_splat - scene3d: lazy-load @mkkellogg/gaussian-splats-3d DropInViewer when a splat exists (rigs/anchors/paths overlay as before); point-cloud fallback intact - scripts/splat_via_modelbeast.sh: train the splat on the MODELBEAST fleet (colmap_poses -> brush_train via the mb queue) and drop it in place - docs/modelbeast-crossover.md: full crossover map (fleet compute, volumetric capture w/ CorridorKey + audio sync, per-moment splats) Verified in-browser: 32MB room splat rendered via /api/splat with overlays live.
