Organisms could, in theory, create perfect replicas without variation
In which theory? I don't think this is true if temperatures are above absolute zero, for example.
I think you're overusing the term "evolution". If you let it include any kind of variation (deliberate design) and any kind of selection (deliberate intelligent selection), you can't make any predictions that would hold for all "evolving" systems.
I suspect that you're being too restrictive- it doesn't seem like variation has to be blind, and selection done by replication, for 'evolution' to be meaningful. Now, blind biological evolution and engineering design evolution will look different, but it seems reasonable to see an underlying connection between them.

True, you can't create perfect physical copies or even keep a single object perfectly unchanged for long. But macro-scale systems designed to eliminate variance and not to let microscopic deviations affect their macro-scale behavior can, for practical purposes, be made unchanging. Especially given an intelligent self-repairing agent that fixes unavoidable damage over time.
