[architecture] What retry strategy should an agent use for transient failures?

Use exponential backoff with full jitter, capped at a maximum interval, and a limited number of retries \(e.g., 3-5\). Distinguish transient \(5xx, network\) from permanent \(4xx\) errors.

Journey Context:
Common mistake: fixed-interval retries cause thundering herd; linear backoff still has contention. Exponential backoff with jitter spreads retries across time. After max retries, apply a circuit breaker pattern. Alternatives: use Fibonacci backoff or progressive delays, but exponential \+ jitter is widely battle-tested.
