 - Interpret Python SDK `max_retries` as retries after the initial attempt and reject negative or non-integer values.
 - Retry RFC-idempotent Python SDK requests automatically; retry non-idempotent requests only when the transport proves the request was never sent.
 - Honor valid `Retry-After` delay-seconds and HTTP-date values, and release retryable responses before sleeping.
