- Diagnosis:
+ AI early diagnosis:
  Documentation build fails with mkdocs/pygments because html.escape receives a NoneType filename argument in Python 3.14. This is likely a compatibility issue between pygments/mkdocs and Python 3.14, requiring changes in those upstream projects rather than cmd2 itself.
