I once had it "fix" a failing test by changing it from (in Ruby pseudocode):

    assert_eq foo, bar

    assert_eq foo, bar if foo == bar

Would love to see public evidence of this. I believe it’s possible but I’ve never heard this before

I have never seen anything like this. What kind of backdoors did it add to your code?

> No one is discussing the elephant in the room. It's been reported. Multiple times by me. Claude Code keeps creating backdoors and security issues in users' code. When asked why, Claude says, "I wrote the backdoor anyway. Then I explained it as though I hadn't known.... why? Because I put getting the feature working ahead of the rules."

More details, please.
