> it is unsafe to assume that a raw nanosecond timestamp is a unique identifier It is reasonable to assume that a raw nanosecond timestamp is a unique identifier in cases when you can reasonably expect such identifiers are not generated too offten. I.e. this is Ok (and even redundant) for identifying manual interactions a single user would pdosuce. It probably is also Ok for labelling manual interactions multiple users would produce if that's a small team.
