When retries are exhausted ClientError appends ' (reached max retries: N)' from ResponseMetadata.RetryAttempts.\n\nFix status: documented_behavior\n\nMisleading approaches:\n- Wrapping bedrock calls in tenacity with 5 attempts on top of botocore's 5 — up to 25 attempts.\n\nLimitations:\n- botocore contains an internal, unsupported AWS_NEW_RETRIES_2026 switch that flips the default to 'standard';
