Step 1
Treat 4xx as client issues: fix the request, auth or entitlement before retrying.
Step 2
Treat 5xx and network failures as retryable with exponential backoff and jitter.
Step 3
Surface a safe message to end users; keep raw provider payloads in server logs only.
Step 4
Persist request IDs from response headers when debugging production incidents.
Step 5
Do not retry non-idempotent POSTs without an idempotency key or equivalent safeguard.
