So the actual bug here, I think, was that when I got an ECC uncorrectable error during the compact operation, I'd discard the wrong block of data. I think it's fixed, time to fuzz more and see...

I'm definitely making progress squishing bugs, early on I was getting instant failures after only a few seconds of fuzzing and they're now far less common with fairly long time intervals between breakage.

Every so often, glancing at the console, I see uncorrectable ECC errors getting logged but it's successfully recovered in every case with this latest code and the object store remained consistent.

Also found and fixed a bug causing excessive padding to bloat log entries by 8-16 bytes depending on flash write block size. This will break compatibility with existing flash images on STM32L431 but I can live with that given that I only have one project using it on STM32L431 at the moment and the only usage of the KVS is for bootloader firmware revision data.
