TSO status is now obtained through an internal system table. This issue has already been fixed. In the system-table path, `MetadataGenerator.java:L2193-L2196` first checks `statusSnapshot.isInitialized()`, and when it is not initialized, it directly returns a not calibrated error, so it will not return that kind of bogus success row with a 'nonzero currentTso + stale window' -- This is an automated message from the Apache Git Service.
