The recordings were there for a week, a month, or a year, and then,
suddenly, were deleted. I experience this phenomenon only with Myth
recordings (and no other files on that volume).

I have a 15T, RAID5 volume that everything is stored to (9T are free), and
it happens to new and old recordings, alike. If you're saying that
something was designed to remove things automatically, then I assume that
you're referring to expiration. However, if things were being expired (if
expiration wasn't completely turned-off), it'd be clipping the records from
the DB, too.

It's a bug, unless someone with more internal knowledge than I do can set
me right.
