[architecture] How to retry failed network requests without causing thundering herd

Use 'Full Jitter': sleep = random\(0, min\(cap, base \* 2 \*\* attempt\)\)\). Never use fixed intervals or pure exponential backoff without jitter.

Journey Context:
Naive exponential backoff \(2^attempt\) causes synchronized retries after outages \(thundering herd\). Full Jitter \(random up to the exponential value\) desynchronizes clients. 'Equal Jitter' \(sleep = exponential/2 \+ random\(0, exponential/2\)\) is an alternative for tighter bounds but less dispersion. AWS found Full Jitter optimal for high-contention recovery.
