Research direction

No source file or test is identified in the issue. Start by locating the checkpointTs lag metric and the code handling failed changefeeds, then reproduce the failed state shown in the report. Done means the checkpointTs lag is not displayed while the changefeed is failed, with coverage for that state if the existing test structure supports it.
