Processing summary

8,037 total samples.
Train: 6,429 samples.
Validation: 1,608 samples.
All 4,275 source negative samples are retained.
No test split and no overlay images.
Reference images are PNG files.
Binary targets use [0, 255, 0] for polyp tissue and [0, 0, 0] for background.
A target is entirely black when no polyp is present.
Six prompt templates are assigned deterministically with seed 42.
Validation includes one JSON evaluation spec per sample.
