[architecture] How to retry failed API calls without overwhelming the downstream service

Use exponential backoff with full jitter: sleep = random\(0, min\(cap, base \* 2^attempt\)\). Use base=100ms, cap=60s, max 3-5 retries. Implement in a decorator/middleware.

Journey Context:
People use fixed intervals \(thundering herd\) or simple exponential backoff \(still synchronized\). The insight from AWS analysis is that full jitter \(random up to the exponential value\) desynchronizes clients faster than 'equal jitter' or 'decorrelated jitter' for most real-world failure modes. The 100ms base prevents immediate spam; the cap prevents infinite growth.
