Rongsong Shen 8974f2cc97 research(raft-ha-core-safety): Phase-4/5 stall root cause — RDHUP-flap spurious failover
Post-Phase-2 chaotic wedge root-caused from frozen soak logs: primary stable
at term 6, but recovered standby ctrl-2 (divergent uncommitted tail 12-15)
cannot reconverge; its primary control channel RDHUP-flaps ~15s, each flap
spawns an unwinnable PreVote failover (peers see primary alive, no grant) ->
timeout -> reconnect -> repeat, so the cluster never reaches stable 3-of-3.
Fix spans Phase 4 (truncate divergent tail + catch up like ctrl-3 does) and
Phase 5 (don't launch unwinnable failover storm on transient RDHUP while a
current-term primary is reachable; reconnect+catch-up first). RED direction
recorded. (Dispatched investigator hung; reconstructed by parent.)
