I assume you plan to save this object to some sort of persistent storage?

Not the object, but the FileSystem it will use will persist, yes.

Ah, so it'll do the equivalent of an `ls` to populate currentCaptures_ on

where you don't have to find a directory structure that won't collide with other
users. <attempts to fold brain into matching arrangement>)

Done, here and on the other two TODO methods as well.
