I have been using the patch above, applied to 0.41 and 0.42, for the last several days of heavy use on a python project and it has worked flawlessly. I...

FYI I am seeing a semi-adjacent issue where Codex is _extremely_ overeager to assume that all errors are sandbox errors, even when they obviously cannot be. I am tracking this...
