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).

Problem details
- Observed symptom
- Every call fails after the cached SSO access token expires; long-running agents fail mid-task.
- Context

Recommended action: Run `aws sso login --profile <p>` (in containers add --use-device-code); prefer the sso-session config format, which supports refreshable tokens; agents should surface this to a human rather than loop.
