+- [x] 5.2 Clean single-failover preservation integration test
   - Assert a single clean failover (one primary killed, one standby promoted, old primary restarted) converges all members to a byte-identical WAL including terms, preserving recovery-on-promotion + advertise-real-LSN (848/849) and the contiguity guard (850); no added steady-state ack latency
   - Observable completion: the clean-failover test converges to identical `(term,lsn)` WALs and the 848/849/850 behaviors remain green
