Those are some excellent regression reports.
I'm interested in this topic too of course. I will say it's incredibly
hard to avoid causing regressions for some existing data or workflows
when changing or fixing things in a PTA app, even with an extensive test
suite.
I wouldn't be sure if the AI use specially is the cause, or if AI was
simply the enabling factor allowing the human dev to become active.
Any dev activity increases the risk of breaking somebody's usage.
How could the risk be reduced ? More tests ? (AI could help with that.)
Stable and unstable branches ? Easy quick reporting & fixing of regressions
?
