-- [ ] 5.2 3-node HA cluster config-push verification
+- [x] 5.2 3-node HA cluster config-push verification
   - Deploy a 3-node HA cluster using the existing deploy tooling (which seeds ctrl-1 from the regenerated `ha/data/cluster.bin`) and confirm peer discovery via `--peers`, listener binding, and worker-liveness tracking behave identically to pre-spec
   - Observable: the 3-node cluster reaches steady state with unchanged peer/listener/worker-liveness behavior, using the regenerated fixture with no error or warning
   - _Requirements: 3.3, 5.4_
