I took an unused disk, set it up with a single pool and copied everything from my two disk system to it using zfs send & recv. I was hoping that if there was something goofy about the state of the filesystems on the older two disk pool it might get cleaned up in the transfer. I tagged the entire set of flac files, they were all successfully validated via the plugin. After exiting Picard, one failed validation. After rebooting, many failed validation. Next I created a new filesystem on this new pool, mounted it, configured Picard to save to that filesystem and ran through all of the tracks. They validated fine via the plugin and by hand after exiting Picard. They also validated properly after unmounting and remounting the filesystem and after a reboot. Sigh. Then I destroyed all of the snapshots on the filesystems that I transfered over from my "real" dual-disk system. Tagging all of the flac files into my home directory generated errors from the validation plugin and by hand after exiting picard. I didn't bother rebooting and checking. So it seems to be something about the filesystem{s} themselves. I'm running a scrub now. g.
