I am not familiar with seatools, but there are usually destructive and
non-destructive test suites in such tools. I hope you have run a destructive
one (which destroys data on disk) as some marginal errors can only be caught by
destructive tests.

I don't think so.

But the journal is passing through on-disk controller, too. If the drive is
mishandling its on-drive cache, then an FS corruption is still possible. Even
if journal writes are "direct", the drive could be ignoring that (i.e. caches
it nevertheless) without flushing it prior to power-off, corrupting the journal
as well.

If the FS survives through reboots, but falters when the laptop is power
cycled, then a cache flush issue is still probable.

Another test method might be hibernation. If resume from hibernation works,
then that rules out on-disk caching problem.
