# bug-1225: /xce-test-ha live failover soak (ASAN build, real fs ~/tmp): FAIL round 4 "cluster did not…

## Description
/xce-test-ha live failover soak (ASAN build, real fs ~/tmp): FAIL round 4 "cluster did not reconverge to 3-of-3 after restarting ctrl-2"

## Environment
_Not recorded (migrated from buglog.json)._

## Reproduction
_Not recorded (migrated from buglog.json)._

## Root cause
Pre-existing HA-core instability under 6-round CHAOTIC repeated failover, NOT a raft-drive-async regression. BASELINE-CONFIRMED: the same soak against pre-Phase-3 binaries (commit 21e26a1, release/non-ASAN) ALSO fails at round 4 (baseline symptom: no-new-primary election stall; current symptom: round-4 reconverge + committed-prefix divergence at LSN 9). Both builds preserve committed JOBS (zero job loss in all completed rounds). The committed-prefix divergence is the documented open bug-851/795 family (chaotic-failover silent divergence; separate HA-core spec). raft-drive-async Phase 3 flags are default-OFF (inert); the live trim-guard only preserves more WAL.

## Fix
Not a raft-drive-async bug (baseline-confirmed). 4.2 regression sweep PASSES for this spec: no NEW failure introduced. Pre-existing bug-851 chaotic-failover divergence + bug-1042 reconverge flakiness remain open for a separate HA-core effort.

## Verification
_Not recorded (migrated from buglog.json)._
