Unfortunately - mypy is known to use heuristics to determine "guessed" types of variables and yes - it is know it will produce different results when different sets of files are presented to it as input. Also we are using caching - and sometimes result of running mypy will differ depending on what is already in the cache. So there are multiple reasons mypy runs might different depending on the circumstances, PR, previous runs. Not sure if we can do anything about it. I have no idea how to make it consistent and also do "incremental" behaviour works - mypy is slow and running it on "all files" for a PR touching only one or two files will take minutes not seconds. The only one I can think of is that for this kind of removals we only look at result of runnig things on "all files without cache" (which is what happens in CI - and use it as "gold standard of what we should hold mypy to". -- This is an automated message from the Apache Git Service.
