• Bedrock sets its own dates (they differ from the model provider's own API). Legacy models: new customers can't use them; existing customers may lose access after 15 days of inactivity.
• aliases are cross-region inference-profile forms (prefix + base ID); not every prefix exists for every model. Scanners should also strip 'arn:aws:bedrock:...:foundation-model/' and '...:inference-profile/' ARN prefixes.
