Start at nexus/tests/integration_tests/oximeter.rs:254 and run integration_tests::oximeter::test_oximeter_reregistration, using the linked test and ClickHouse logs to investigate the intermittent timeout. Done means the test reliably observes new data after restarting the producer without timing out.
