UD* (trace of the universal dovetailer) is a continuum, AFAICT. It has the cardinality of the reals, and a natural metric (d(x,y) = 2^{- n},
where n is
the number of leading bits in common between x and y). ISTM, this
metric induces a natural measure over sets of program executions that
is rather continuum like - but maybe I'm missing something?

I always assumed the UD output bits - i.e. not a continuum, but a
countable infinity of symbols - but maybe I'm missing something?

Am I missing diagonalisation? i.e. Can the UD output be diagonalised?

The UD doesn't output anything. If it did, then certainly, the output
could not be an uncountable set due to the diagonalisation argument.

Rather UD* is like the internal view of the operation of the
dovetailer, like the sum of all possible experiences of the Helsinki
man being duplicated to Washington and Moscow that is being discussed
rather a lot lately.

OK. That's the correct explanation.
Still UD* is an enumerable structure, but seen as the global domain of all 1p-indeterminacies, it acquires a non enumerable structure, due to the first person "unconsciousness" of its working "time".
