Ruff supports file-level noqa comments: # ruff: noqa: TC002 on its own line at the top of a file will lead to the TC002 code being suppressed for the whole file. RUF101, however, appears not to detect these file-level comments when it looks for redirected rule codes; it only flags inline noqa comments of the form # noqa: TCH001.

For example, I would expect Ruff to emit a RUF101 diagnostic on the first line of this snippet, since Ruff's flake8-type-checking rules have been recoded from TCH to TC. However, no RUF101 diagnostic is emitted:

# ruff: noqa: TCH002
