180-region
Region-conditioned defect QA on woven fabric — 305 items, derived deterministically from the
binary segmentation masks of AI4Manufacturing/180. Exact-match gradable → SFT and
RLVR-ready.
Task
"A region is indicated — what defect, if any, is there?" One item per defect instance
(114 positives: Fuzzyball 39, Nep 17, Broken yarn 13, Broken end 10, Broken pick 9, Cut selvage 9, Crease 5, Warp ball 5, Weft curling 3, Knots 2, Weft crack 1, Contamination 1) plus 191 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 154 / bbox_text 151):
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 = the type name (closed list) or 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/180
— AITEX woven-fabric surface inspection — 247 fabric-strip photos, 12 defect types + good; each anomalous image has a paired binary pixel segmentation mask (binarized at gray>40).
Generator: annotate/180/build_180_derived.py in forge_model; machine gates
annotate/180/verify_180.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 4096×256 grayscale strips (16:1 aspect; 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
180).
