single word requests - Shorter equivalent to (un)replaced

This may be aimed more at developers; but lets say you have a string with a possible variable in it assigned to another variable.

$myVarBeforeReplacement = 'some_string_with_{var}';

Then after some manipulation you get the desired string by replacing that variable

$myVarAfterReplacement = 'some_string_with_its_var_replaced';

I am trying to think of two separate but somewhat related words to describe the string in each stage. I don't want to use processed / unprocessed as that can imply at the other processes going on.

Similarly I don't want to used formatted / unformatted since the string can also go through formatting. Replaced / unreplaced seems a little long winded and antiquated.

I was leaning on raw but cooked(?) makes no sense.
