Unreplicated, the site-x survivor came up empty (by design: no LocalDb peer); replicated, kill and freeze each lost only the 26-30 s takeover window, every buffered message was delivered once, and the 4 duplicate ticks came from the frozen victim's 6 s zombie window. Central kill: 0 gap. Claude-Session: https://claude.ai/code/session_01GT67ACmpMR7b9LGRPLijMi
