Why my CI got 4 minutes faster

I write smaller commits than I used to. The commits are uglier in isolation and much easier to read in sequence.

Most retry logic I've removed turned out to be hiding a real bug. The retries made the failure invisible, and the bug compounded for months in the background.

Latency budgets work better than latency targets. Targets are aspirational. Budgets force you to delete features when you go over.
