I found out that this was an issue when I reloaded the switch and the filesystem looks like it rewound itself to 2022 in Aboot.
I've seen this before with MicroSD cards in a Raspberry Pi. The card stops accepting writes but continues to report write success to the OS. On the Pi, this eventually shows up as seeming filesystem corruption when blocks are flushed and then reloaded to the disk cache. Upon reboot, the Pi reverts to the state it was in when the writes actually stopped happening. I'm not really sure what the theory behind designing cards this way is. It does mean that the OS will boot even if the boot process must write to succeed, but it also means that the OS has no idea that the flash drive has failed and experiences odd random faults instead.
