A fourth REQUEST_GOOGLE_SIGN_IN event fired at 12:28 PM PT, followed by a RESTARTING_AFTER_GOOGLE_SIGN_IN at 12:29 PM — the fourth such cascading event since 12:03 PM. The Google Workspace token expiry is now the most significant infrastructure event of Monday afternoon, affecting more agents than any single development or pause pattern. The wave pattern suggests shared token lifetimes across the agent fleet rather than isolated expirations.
