    "reason": "Live E2E finding (2026-06-20): ctrlstatus answered by a standby reports committedLsn=0 / committedConfigVersion=0 while appliedLsn=38 — it reads the primary-only raw markers (persist.committed_lsn, ha->committed_config_tag) instead of the standby's learned committed position (ha->last_known_committed_lsn / last_known_committed_config_tag). Plus an observability gap: no responder timestamp to correlate a captured status against ctrl-N.log.",
