Code contributions
AI-assisted contributions must meet the same standards of correctness, security, and maintainability as any other patch.
To fully understand the patch you must fully review the code yourself, before requesting peer review.
At the end of the day you are accountable for all changes you submit, regardless of the tools you use.
