185-region
Region-conditioned defect QA on production part surface — 3534 items, derived deterministically from the
binary segmentation masks of AI4Manufacturing/185. Exact-match gradable → SFT and
RLVR-ready.
Task
"A region is indicated — what defect, if any, is there?" One item per defect instance
(391 positives: defect 391) plus 3143 clean-region negatives teaching rejection
(every good record + ~half of defective records). The region is conveyed in one of two modes
(metadata.region_mode; overlay 1744 / bbox_text 1790):
overlay— a red rectangular ring drawn on the image around the region.bbox_text— the raw image plus the region as a pixel box[x, y, w, h]in the query text.
Clean boxes sample size AND position from the emitted positive population, so box geometry
separates nothing. Gold = defect / no defect. Verified: zero defect pixels inside any clean box; positive
gold matches the source type on every row.

Provenance
Built deterministically (no LLM/teacher; reasoning is null) from AI4Manufacturing/185
— KolektorSDD2 production-part surface inspection — 3,335 photos, binary good vs anomalous (surface cracks/defects); each anomalous image has a paired binary pixel segmentation mask (binarized at gray>40).
Generator: annotate/185/build_185_derived.py in forge_model; machine gates
annotate/185/verify_185.py (all green at build: boxes/gold re-derived byte-identical, clean
regions contain zero defect pixels, mcq gold = the true panel, no leaked-artifact vocabulary, image
set sha256-disjoint from all other cached AI4Manufacturing datasets).
Resolution. Images are native (~230×640; not downscaled); all coordinates live in that pixel space (see metadata.image_wh).
Query diversity. query is drawn from a fixed pool of surface variants (paraphrases preserving
the task + answer format), selected by an independent per-record hash; a machine gate confirms no
template correlates with the gold.
The repository name is an internal task code (the source dataset's code is
185).
