 Current phase-3 notes:
 
 - header detection now tolerates minor `top` misalignment across the `A-E` header glyphs
+- row boundaries can snap to the last affix-to-prose transition between adjacent roll labels when midpoint slicing would leak into the next row
+- affix symbols are learned from the footer legend before body parsing, so symbol-only affix fragments are classified correctly
 - footer page numbers are filtered out before body parsing
 - validation allows a single contiguous affix block either before or after prose
-- `Mana.pdf` is intentionally left out for now because its row-anchor geometry and notation still need dedicated handling
