No controlled benchmark suite has been completed for Aider yet, so this verdict cannot be cited as final proof and Aider is not eligible for "Verdict Certified" status. When a verified run lands, it will appear in the Evidence Timeline below and the status badge above will switch to "Verified".

Failure modes we'd watch

  • Quality varies sharply with the model chosen
