The problem as I see it is stirring a can of paint would be "evolution" under your definition, and I simply will not accept that.
We need to keep the word "evolution" meaning something other than "change" or we'll have a situation where some jerksilly postal bureaucrat comes up with a new name for the "change of address" form ~ she'll want to call it "address evolution", and then where will we be?
Lost!
This post seems to be where you lost your way on the word "change".
Evolution is a change in allele frequency in a population over time. Evolution is not a property of individuals. It is a property of populations. What changes is the percentage of a population having specific traits.
The source of variation is not crucial to the dynamics of change. It could be stochastic or it could be engineered by humans. What makes the change significant to evolution is whether the change results in differential reproductive success. And of course that can involve human intervention. In the long run the dynamics are the same.
