Insight for: 大量账号失效

This issue reports a catastrophic failure: '80% of accounts invalidated' with a '401 Encountered invalidated oauth token for user' error. This indicates a widespread problem with OAuth token management, likely due to token expiration, revocation by the external service, or a fundamental flaw in the token refresh mechanism. The pain point is the complete loss of access to a vast majority of provisioned accounts, rendering the `codex-console` unusable for its primary purpose of managing external services. Market implications are dire for any SaaS product relying on OAuth for persistent access. Such a high rate of account invalidation signals a critical vulnerability in the system's ability to maintain user sessions, demanding immediate attention to token lifecycle management, refresh strategies, and resilience against external service policy changes.
