Ever since I started using Claude at its inception this was the biggest breach of trust that I've experienced.

I'm afraid to have touch my code base because a nerfed model could slip in stupid bugs.

This is also why a weaker local model might be preferable because it allows me to calibrate trust, and my expectations don't change.

I have had Astra analyze my long running Opus conversations and the degradation definitely happened on November 6th and 7th.
