"""v1.7.6 — guard: the agent must surface keepalived FAULT state.

A VIP whose interface has no usable IPv4 (or whose track-script fails) puts keepalived into
FAULT — the virtual IP is NOT held. Previously get_keepalive_state only grepped (MASTER|BACKUP),
so a FAULT'd VIP reported as BACKUP — misleading (looks healthy-ish). It must report FAULT so the
UI shows it red. Both get_keepalive_state copies (installer + SKIP_TO_DAEMON daemon) must include
FAULT. Pure source guard."""
