Dummy question… when I run

sst remove --stage xxx

… how it know which stages has to remove? it compiles my current code to get the existing stages “in code”? or calls CF to pull existing stacks? Asking this because sometimes I modify an stack-name locally, but on AWS there is still the same stack with other name. What would happen in that situation? is going to remove my old stack or not?

Yeah right now if you modify a stack name and deploy, it won't remove your old stack because cdk has no way to tie it together. Probably correct behavior
