Profiles bind a RAM-booted root image to overlay templates; assigning a machine allocates a node name and management IP, writes the per-MAC PXE entry with a per-node token and exports static leases for dnsmasq. Nodes pull rendered overlays (hosts, slurm.conf from inventory, gres.conf, SSH host key, munge key) through rollcall-overlay.service; the runtime refresh timer is the heartbeat. Adds the compute-debian13 image definition and a generic live-build root image script, CLI and web UI for profiles/assign. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
