The most egregious examples are always lazy (big diff, lengthy descriptions, weird phrasing,…). Now there’s a section in the policy to point to for the quick rejection.
> My code is clearly AI "assisted"
No such thing, it's 100% your code, regardless of how it came to be.
"Assisted" does not necessarily mean "authored", which is the point of the comment you're replying to; helping you review the code is "assistance", even if no code was written.
Curiously, https://github.com/qgis/QGIS-Enhancement-Proposals/pull/387#... shows that at least some contributors realize the vagueness of the policy, but they don't seem to care, which is rather unfortunate.
Possibilities range from "public domain" to "the cancer Microsoft accused GPL-licensed code of being". In no plausible scenario does the person who pressed the "generate slop" button become the copyright holder.
