Answering whether the caption merge breaks the page-space key in eval/chapter-truth.json. It does not. _merge_plan only groups adjacent fragments and slice_webtoon cuts at gutter midpoints, so a vstacked panel's [x, y0, w, sum(heights)] is the exact page region. The defect is one line up. slice_webtoon skipped any segment shorter than min_seg instead of absorbing it, so this chapter's 116 panels have a 62px hole between panel_order 70 and 71 and lose 18px at the strip's end. A merge spanning that hole reports a bbox 62px short of the page span it covers, and every consumer mapping a detection back to the page is then wrong by that much, silently. The 62px held the credits line, found at p_050.png row 338. A short band is now held and absorbed by the next segment, or by the previous one when it is last. min_seg still suppresses a tiny panel and no strip pixel is discarded. The self-check asserts the bboxes tile the strip end to end. Checks: worker_crop.py self-check passes and fails on the old code, where the first band starts at 49 instead of 0. ruff check . exits 0.
