[architecture] Retry storms overwhelming a degraded downstream service \(thundering herd\)

Implement truncated exponential backoff with full jitter: sleep = random\(0, min\(cap, base \* 2^attempt\)\). Cap maximum delay \(e.g., 60s\) and limit total attempts before circuit breaking.

Journey Context:
Fixed intervals cause harmonic resonance; exponential without jitter causes synchronization as clients started together retry together. Full jitter breaks synchronization by randomizing wait time within the interval. Tradeoff: longer tail latency for individual requests versus system stability and downstream recovery.
