I had the same association but interestingly this version appears to be a "remix" of TigerBeetle's style guide, by an unrelated individual. At a glance, there is a lot of a crossover but some changes as well.

I think the point is well made though. When you're building something like a transactions database, the margin for error is rather low.

Then I'm curious about what their principles on deadlines. I don't see how it aligns with their coding styleguide. Taking the TigerStyle at face value does not encourage deliverance. They're practically saying "take the time you need to polish your thing to perfection, 0 technical debt".

But ofc, I understand styleguides are... well.. guides. Not law.
