What is black warrant cast?

I lack the ability to provide information about a "black warrant cast" as my knowledge base is limited and that specific term is not widely recognized. It could be:

  • A misspelling or a term specific to a niche area: It's possible there's a typo or the term refers to something obscure.

  • A misunderstanding: The user might be confusing different concepts.

Without more context, I can't offer any meaningful information or create links.
