So... there's nothing besides "being able to get root" from preventing one from reading EEPROM to unlock ./pairFact3?

There's nothing besides "being able to get root" preventing you from doing anything practical. There's no secure boot.

I'm guessing sniffing the I2C lines wouldn't help you b/c it's asymmetric key exchange? (I'm fairly clueless about crypto)

(Assuming you decided to go that route/getting root wasn't feasible for some reason)

I don't know the details of the crypto involved; ISTR it's vulnerable (but not trivially so, needs days of compute).

But that hypothetical is not useful because the design does not have real security; if it did it would be a different design!
