Does Debian have a rule that forbids (or a taboo that proscribes) contributors passing off other people’s work as their own? I could believe that such a rule is implied rather than written down. The GR could be about writing it down, and it would surely cover the case of code that came directly from a model. Even if we don’t consider a model to be another person it is certainly not the contributor’s own work.

(If anything, the copyright to model-generated code cannot possibly be said to belong to the human contributor. They… didn’t write it! I’m glad to see that aspect was discussed though I’m surprised it wasn’t the main thrust.)
