A mention extended over a stored name's optional outer punctuation only when the reason spelled all of it, so "Like your Beef Chili!" left the mention of "Beef Chili!!" at "Beef Chili" while "Chili!" extended through its "!", and neither covered the other. Extend through the longest portion of the punctuation the reason spells after which the border still holds, at either end of the name. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
