The substrate machines are now rendered from the live k3s nodes (arch, cpu, memory, GPU, k3s version), read in-cluster via the mounted ServiceAccount with a stdlib HTTP client (no client-go) and a 30s cache; falls back to the authored substrate whenever the cluster is unreachable. Placement per the homelab decision "in-cluster only for in-workload ops" — a running web app rendering live data fits. HostsFromNodes parser built test-first. RBAC (read-only node-reader SA) shipped in infra k3s/apps/cad-atlas/. Verified: go build/vet/lint(0)/test green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
