The only condition of the diagonal argument is a_nn =/= b_. That has
noting to do with a limit (which is not a diagonal and not the
antidiagonal).

If 0 is not a term of the sequence then 1/9 is not a diagonal number.
That is no confusin but a clear cut arguing.

Right. But neither 0 not 1 are part of the list.

Now you show your inconsequence. Sequence and series behave alike
beause every series can be expressed as a sequence.
