Graham, Everything is fused - just not in the diagram. So yes, the Enterprise is compliant. And I have a 2019 survey to prove it.
And it’s “Khan” — though I did know a Jewish kid from Great Neck, Long Island named Kahn who was a bit of a nutjob. Doubt he was capable of any wrath though.....

Not sure I'd go so far as suggesting you be banished 'tho - seems a bit harsh. Plus people who get banished turn into psycho nutjobs like Kahn, we don't need that kind of crazy.
