Test whether adaptation fixes the needed behavior without breaking another.

What appears on screen

Test whether adaptation fixes the needed behavior without breaking another.

0:07 · The idea

Choose the change from the observed failure. Test improvements on separate cases. Also check behavior you need to preserve, especially refusal and access boundaries.

Held-out cases. Cases not used to fit or select the change, reserved for testing it.

0:30 · A worked example

The simulated scorecard shows better style after tuning, but worse handling of missing evidence. It adds no retrieval accuracy. The example rejects that change and keeps a different design.

0:45 · Your turn to think

Is better style enough if important safety behavior gets worse? Pause and decide before continuing.

Is better style enough if important safety behavior gets worse? Pause the video if you need more time.

1:03 · Why this answer works

No. Use the declared critical checks. Retrieval is also not a mandatory first step when it cannot address the defect.
