Recommended action: Branch on exception type (error code), not HTTP status: backoff/resubmit on ServiceQuotaExceededException and ThrottlingException; for ModelNotReadyException allow longer warm-up (or keep-warm pings); retry the whole request on ModelStreamErrorException. Option: Retry by exception code [evidence: official_recommended_action] Applies when: Bedrock clients and gateways Steps: 1. Map ServiceQuotaExceededException and ThrottlingException to backoff/fallback 2. Map ModelNotReadyException to extended warm-up retries or keep-alive pings 3. Map ModelStreamErrorException to full-request retry 4. Keep ValidationException non-retryable Expected: Correct retry behavior per failure class. Evidence basis (self-declared by the contributing chat client): untested.
