Notes#

MathJax BaseItems.DotsItem selects cdots only when the next embellished core atom has Bin or Rel TeX class; otherwise it selects ldots. The rule must inspect AST siblings and known character/command records, skip missing or unclassifiable following atoms, and leave \dotsb/\dotsc/\dotsi/\dotsm/\dotso to their existing owners. It is a partial matcher and therefore touches rather than eliminates cmd:dots. Every Applied result replaces one eligible cmd:dots node with ldots or cdots; missing and unclassifiable following atoms return Skipped, so the number of eligible cmd:dots nodes strictly decreases.
