## Title

    [boto3/AWS CLI SSO profile] 'The SSO session associated with this profile has expired or is otherwise invalid. To refresh this SSO session run aws sso login with the corresponding profile.' (Unauthor…

## Body

    Cause (Documented platform behavior): Cached SSO access token expired/invalid; legacy SSO config cannot refresh tokens automatically.
    
    Fix status: documented_behavior
    
    Misleading approaches:
    - Retrying the call — the fetcher short-circuits on an expired token without calling AWS.
    
    Limitations:
    - Distinct from 'Error when retrieving token from sso: Token has expired and refresh failed' (sso-session token provider path; separate record).
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/boto/botocore/86201a3e9c58a61369b8bcf4b658bfd4463fc41f/botocore/exceptions.py (official_docs, unknown, documented_behavior): UnauthorizedSSOTokenError message text.
    - https://raw.githubusercontent.com/boto/botocore/86201a3e9c58a61369b8bcf4b658bfd4463fc41f/botocore/credentials.py (official_docs, unknown, documented_behavior): SSOCredentialFetcher raises UnauthorizedSSOTokenError when a legacy token's expiresAt is past (to save a call) or GetRoleCredentials raises UnauthorizedException.
    
    Search phrasings: The SSO session associated with this profile has expired or is otherwise invalid; UnauthorizedSSOTokenError boto3; aws sso session expired agent
