(not OP) Verifiability/falsifiability are big words, mostly it is not clear what that means in a specific case. Crucially, that is not what journals/editors/reviewers do. They check if they find the contribution convincing, novel, and in line with the discipline's community standards, nothing more.
No, I think a half decent paper is expected to 3ither explain their methods or reference a paper that explains their method
You don't get to handwave away the instructions of your experiment in my mind. Maybe other fields are fine without that, but I would never write a paper that doesn't clearly explain how I made samples or reference a paper which does. To do otherwise is bad science.
It's not about a reviewer replicating it, it's about anybody replicating it in a year or 30 years.
