Ran vyos001's real running config plus the real production delta on the labsim
router -- same VyOS version, isolated OVS bridge with no physical NIC, so the
sim briefly holding vyos001's actual addresses could not reach the real LAN.
Result: all 317 commands accepted and the whole delta commits (COMMIT OK), the
revert is byte-exact, and auto-revert fires without rebooting (uptime and
boot-id unchanged across it).
Also written down are the two things this did NOT establish, because a runbook
that overstates its own coverage is worse than one that admits the gap: PPPoE
cannot be tried while the USG holds the single available session, and the
rehearsal ran with vyos001's eth2/eth3 stanzas stripped because the sim VM has
two NICs rather than four.
