Understood, thanks for looking at it so quickly. I'll drop the patch. > Did you forget an Assisted-by: tag? Yes. The patch was AI-assisted and should have included Assisted-by: Claude:claude-opus-5 Assisted-by: Codex:gpt-5.6-sol I worked from submitting-patches.rst for the tag order and did not read coding-assistants.rst. My mistake, and it will be on anything I send in future. Thanks, Ruslan
