Synthesis Proofreading Translation Summarization Critique
It may just be a misreading but say you asked for a review of the text and it silently water marked it as its own. Guess source control to review changes is the solution.
If your writing is indeed your work then watermarking should not affect you.
I think the key concern here is that a statistical "watermarking" system could insert a positive signal even when the gradual changes are--to any human watching the editing process--not things we would consider disqualifying.
...that seems correct to me? Why wouldn't it be marked? If you take the model's suggestions and apply them, those should absolutely be marked?
