Material Replacement Bench v1.0

Frozen evaluation split for the interior-design material-replacement benchmark: 1421 task specs (mask-aligned, watermark-free), of which 1093 are gt_clean (the stored output edits only the mask and matches the reference; the rest keep output as a non-exemplar reference solution only).

Task: given input + mask + reference (or the mask-free instruction), replace the masked object's material and change nothing else. Evaluation is reference-free — outputs are scored on material correctness, outside-mask preservation, geometry preservation, and lighting harmony, never on pixel similarity to output.

Columns: instruction (rewritten, image-faithful), material_category, surface_type, mask_target_seen, mask_coverage, coverage_bucket, gt_clean, plus the four images.

Provenance: fully synthetic quadruples generated with OpenAI image models via codex; curated from Elfsong/vinhome_material_replacement (algorithmic QC + VLM semantic QC + instruction relabeling; see curation/ there). Frozen 2026-07-20. Research use.
