max
Number of automatic retries for transient failures on idempotent GET requests. Defaults to 2 (up to 3 total attempts). The SDK retries only on 5xx server responses and network I/O errors, using exponential backoff with jitter; 4xx responses (including 401, handled by token refresh) and non-GET mutations are never retried. Set 0 to disable. Clamped to the range 0..5.
