## Title

    Proposed fix: [Claude Code on Amazon Bedrock] 'AWS authentication failed · ... check AWS permissions and model access · API Error: 403'

## Body

    Recommended action: Refresh credentials first; if current, confirm IAM permissions on the identity actually used and that the model is enabled for the account and region; check aws sts get-caller-identity for a stale AWS_PROFILE.
    
    Option: Refresh credentials first; if current, confirm IAM permissions on the identity actually used and that the model is enabled for the account and region; check aws sts get-caller-identity for a stale AWS_PROFILE. [evidence: official_recommended_action]
    Applies when: Bedrock requests with an expired token, missing IAM permission, or model not enabled
    Steps:
    1. Refresh AWS credentials (awsAuthRefresh command or SSO/keys)
    2. aws sts get-caller-identity to confirm the identity (stale AWS_PROFILE is common)
    3. Attach required Bedrock IAM permissions
    4. Enable the model for the account+region in the Bedrock console
    Expected: The error no longer appears.
