Good question. I had assumed that statements are added only after they've become false, so the 1st and 3rd of your examples would have been added on or around 01.01.2019 and 01.01.2022 respectively. As to boats vs flotsam (the 2nd), I've already used up my thinking-about-Musk budget for the next couple of years, but since you've nerd-sniped: floating Teslas weren't cargo, so they're not flotsam; they weren't deliberately thrown overboard, so they're not jetsam; and as they haven't been abandoned, they're not derelict; but as I doubt they can navigate, unless they're displaying vertical lights or balls they're not conforming boats not under command, either.
