manifesting as decider/input self-referencial conflation, resulting in
the contradiction at the heart of the halting problem being a category
(type) error, i.e. ill-formed.

The input also needs to be of the category "Program", but provided via a
representation. The act of representation lets us convert items of
category Program to the category of Finite String which can be an input.

 Those two categories you have identified are different hence the category
error.
 

That is correct. A running program and an input finite
string ARE NOT THE SAME.

 Such composition is invalid.
 

Richard is trying to get away with saying that a
finite string THAT IS NOT A RUNNING PROGRAM
<IS> A RUNNING PROGRAM

What is the category error?

 A category error (also called a category mistake) happens when we talk
about something as if it belonged to a logical or ontological class it
simply doesn’t fit. In other words, we mis-sort an object, property, or
question into the wrong “bin,” so the statement can’t possibly be true or
false—it’s just confused. -- ChatGPT

Like the question: What time is it (yes or no)?
I came up with that 20 years ago during my work on the HP.
