Thanks for the detailed review
I wouldn't call that detailed. It was what glared at me from skimming for a couple of minutes.
was calling pip install --break-system-packages at runtime, which is indefensible
"You" still have three instances left of runtime pip install --break-system-packages without user interaction, one of which dead code.
I think the follow-up beautifully clarified the "is this vibecoded?" question too.
Labeling it 1.0.0 seems premature to say the least.
