What does HHHH (Goofball) mean?

HHHH is the system's emergency assignment when your brain refuses to match any ordinary pattern cleanly enough. The standard type library throws up its hands, laughs nervously, and gives you this badge instead. It is part apology, part diagnosis, part cosmic joke. Your mind does not walk where the map expects. Sometimes the only honest description left is a long, slightly unhinged laugh.

This type belongs to a special result branch and does not participate in the standard 15-dimension pattern matching pool.
