Start with the atlassian_confluence system test: api and the audit DataStream, then compare the failure in Buildkite build 46081 with the latest failed builds. Trace why the expected hits are missing from logs-atlassian_confluence.audit-29173; done means the test finds the expected hits and passes in a new build.
