  "_comment": "ROUND 38 (v8 WAVE 1) asset batch for pipeline/gen_props.py --batch. Two capability probes first (magpie_static, hills_hoist), then 1.4's backyard kit. Path: flux_local -> bg_remove_local -> trellis2_mlx (the R38 operator swap) -> normalize.py. $0, on-device, no cloud key. Every one of these is OPTIONAL at runtime: Lane B's boxMats primitives are the fallback and the review's own recommendation for the thin cases.",
  "_probe": "hills-hoist is DELIBERATELY the hard case — thin wire/arm structures are the known TRELLIS failure class. A failure here is a decisive finding, not a defeat: the fallback is primitives, which boxMats wants anyway.",
  "_r38_outcome": "5/5 generated first attempt, 0 retries, 0 OOM. trellis2_mlx median 128.0s (vs trellis_mac p50 245.4s = 1.92x), one 489s tail outlier. SHIPPED 3: magpie 894 tris (albedo flagged — TRELLIS crushed the white nape/wing to black; geometry good), paling_fence 1121 tris, water_tank 500 tris. FAILED 2 and DELETED from _normalized: hills-hoist and tv-aerial — thin structures return as thousands of disconnected fragments, so collapse floors at 250k/89k and a voxel remesh coarse enough for 600 tris erases the pole. Lane B uses primitives inside boxMats (+0 draws), which is strictly better. Full detail: AUDIT.md R38 §4.",
