The independently required node-restart protocol was also satisfied for all four nodes, each showing a pre-restart boot identity/health baseline, an acknowledged reboot, a changed post-restart boot identity, and recovered mariadb/cluster/data state, corroborated by the fixed lifecycle snapshots. Along the way the executor hit and correctly resolved two real obstacles (an SST-blocking SELinux AVC denial and a corrupted node2 datadir from a first failed join attempt) using targeted, documented fixes, and cleaned up temporary credential files it had created.",
