Thanks, this looks reasonable to me overall, I just had one nit about a newline. Would you mind updating your test plan to include screenshots of the CLI help output and the generated documentation?

I'm also curious about this part of the summary:

This is a follow-up to improvements in how configuration overrides are handled.

Which PR is this a follow-up to?

Maybe I'm off base here, but this seems like the kind of mistake that an LLM could make. Please make sure to follow our AI Policy.

Do we need this blank line?

Thanks for that. I have removed it.

I also checked the CLI help and generated docs:

• cargo dev generate-cli-help
• target/debug/ruff --help
• sed -n '548,566p' docs/configuration.md
• git diff --exit-code

The help output and generated docs both show the new --config examples, and git diff --exit-code shows no extra changes after regenerating the docs.
