When talking of their earlier Lua code:

I was surprised that a rules-based system was not tested completely, perhaps because the Lua code is legacy relative to the newer Rust implementation?
It tracks what I've seen elsewhere: quality engineering can't keep up with the production engineering. It's just that I think of CloudFlare as an infrastructure place, where that shouldn't be true.
I had a manager who came from defense electronics in the 1980's. He said in that context, the quality engineering team was always in charge, and always more skilled. For him, software is backwards.
