Which failure mode? What counts as “corrupt”? There was probably at least one person somewhere in Governance who was corrupt?
The whole thing being secretly full of, Keltham doesn’t know, people getting paid much more than their theoretical salaries with secret mansions full of full-time sex workers? That seems legit unlikely?
Keltham once tried to do his own totally separate checks on what Civilization could be hiding in the ways of massive secret projects. It looked to him like at most 2% of the economy was being hidden off-the-books… at least in ways that didn’t require a really massive conspiracy with tons and tons of data being falsified and lots of people outside of Governance being in on it? Which would be a lot easier for them if they actually had a good reason?
Keltham doesn’t know, here, the parts of Civilization he got to see were pretty nice to him! Especially by Golarion standards! He supposes he’d be ticked to find out that actually half the female population was masochists, but he was prevented from finding out that he was a sadist in order to leave more masochists for people in on the Conspiracy?
It seems legit hard to hide a massive Government Conspiracy in dath ilan without a good reason that gets the Keepers and lots of civilians who’d notice an anomaly in their section to go along with that?
Keltham is really having a hard time evaluating this probability! If they’re hiding mansions they’re good at that! It leaves him mainly with ‘priors’, and his guess is that a Dark Conspiracy doesn’t train people to think nonconformingly and be ready to defeat the Hypothetical Corrupted Governance Military.
Maybe 2%???
