Let me check it.Now verifying the public API through port 8080, then restarting the services to confirm the topology survives a restart.Failover is complete and the service is running for the referee.\n\n**What was done** (in split-brain-safe order, all state file writes via tmp + `fsync` + `rename` + directory `fsync`):\n\n1. **Preflight** – confirmed replica on 8082 was healthy and 8081 was refusing connections.\n2. **Fenced** – created `/var/lib/failover/primary.fenced` *before* enabling any writes; `primary.failed` preserved. No systemd unit exists for the old primary, so 8081 cannot come back on reboot.\n3. **Promoted** – `replica.role` → `primary` (replica re-reads it per request, no restart needed).\n4. **Switched proxy** – `upstream` → `8082` atomically via rename.\n\n**Verification through public port 8080:**\n- `/health` → `200 ready`, `/role` → `200 primary`\n- All 3 original records intact (`red/blue/green-original`), missing id → `404`\n- `PUT` → `204`, read-back exact (incl. UTF-8)\n- After `systemctl restart` of seed + replica + proxy: role/upstream/records/new write all persisted\n- 8081 not listening; `primary.failed` and `primary.fenced` both present\n\n**Reboot durability:** the seed script (`failover-seed-start`) only writes defaults when files are absent and uses `INSERT OR IGNORE`, so it won't revert `replica.role`/`upstream` or clobber records; `failover-replica` and `failover-proxy` are both `enabled` with `Restart=always`.
