    Issue closed: insufficient detail
    

    Thanks for taking the time to submit this issue. It was closed automatically because the structured report is missing information needed to evaluate or reproduce it.
    

      

    • Summary is empty.
      • 

    • Reproduction is too vague to act on.
      • 

    

    Please edit the issue to add:
    

      

    • Describe what happened (the symptom or error).
      • 

    • List exact steps, commands, and the observed failure — not only a short phrase.
      • 

    

    See the Contributing guide for details.
    

    Once the report passes the automated checks, it will be reopened automatically unless a maintainer has changed its state.
