Build login-session into both images as the swapped root shell, add a quarantine bind mount for telnet (symmetric to SSH), seed transcripts/ dir and service discriminant at entrypoint. Deployer syncs sessrec.c + Makefile into each build context alongside the existing syslog_bridge helper. sessrec falls back to /etc/sessrec.service when env is stripped (busybox /bin/login).
