ABO material-intrinsics WebDataset

Preliminary publication smoke for the IDArb-compatible Amazon Berkeley Objects material-render conversion. The smoke shard contains 10 complete objects with 91 views and three environment lights per object.

Each tar member is one compressed NPZ containing rgb, albedo, roughness, metallic, normal, mask, depth, and meta_json. Source-specific material channels, camera conventions, normal axes, masks, and background compositing are normalized during conversion.

Production publication is in progress. Root shard-*.tar files contain exactly 500 unique objects except the final source remainder; matching provenance and SHA-256 records live under manifests/. smoke/shard-000000.tar remains the independently verified validation artifact.
