Exploratory replay, 11 November 2026. Keep upstream revision, config, order, shared classifiers, seed, mapped polygons and majority-area rule as frozen. Observe each pipeline step (including saveFinalMask). Start with the initial mask. Store each field’s mask window and whole-slide positive pixel count. Record four-connected component counts and largest component immediately before and after finalProcessingArea. Require all 26 final PNG hashes to reproduce before attribution. For the original 52 switches report first appearance of their exact final direction and entry into their final uninterrupted run, plus intervening losses of that direction and any opposite-direction stages. Also tabulate temporary discordance in final-concordant pairs. Describe behavior under this pipeline order only. No parameter tuning or new sampling.
