Four-model YOLO segmentation ensemble for weld-surface defect inspection.

Inference runs locally after downloading the weights from the Hugging Face Hub. No Hugging Face Inference Endpoint is required.

The first call downloads and caches the four weights. Subsequent calls reuse the local Hugging Face cache.

This is a proof-of-concept weld surface inspection system. The score and PASS/REVIEW/FAIL rules are prototype decision logic and are not welding-code acceptance criteria or a substitute for qualified human inspection.
