One segment at a time. Red = ARCADE ground-truth (reference). Green = the new segment to judge. Tap TRUE or FALSE, then 💾 Save & next to store and advance (moves to next model at the end). Toggle buttons hide either overlay to see the raw image.

Red overlay = ARCADE GT segments (reference, not clickable). Green overlay = the one new segment to judge. Tap TRUE or FALSE, then 💾 Save & next to store it and advance. At the end of a model's list it moves to the next model. Click the segment to cycle TRUE → FALSE → unlabeled; ← → keys to revisit. Use the two toggle buttons to turn off red or green and see the raw angiogram. 🔎 FP/FN review: connected components where the latest model and the corrected GT disagree — pink = model pick without GT (TRUE → adopt into corrected set, FALSE → reject), violet = GT the model misses (TRUE → confirm, FALSE → remove from corrected GT). Segments shorter than 40px, thinner than 8px, GT-hugging width rims and tiny edge artifacts are auto-skipped (shown in the message). 🖌️ brush with "unmarked only" paints areas neither GT nor the model marked — saved straight into the corrected dataset.
