initial QEMU slice, backed by imported contracts for majors 6–9. - Implement durable handlers for access/auth, cluster, LXC, storage, HA, firewall, Ceph, SDN, ACME, notifications, pools, mapping, and node ops - Serve an interactive Web UI with catalog browsing, demo seed controls, and OpenAPI/help surfaces - Bundle PVE 6.4-15, 7.4-16, and 8.4.5 contract revisions alongside 9.2.3 - Support in-memory runtime contract Apply (POST /ui/api/contract/apply) so /version and /api2 routes follow the selected major until restart - Expand seed profiles (including demo-cluster), migrations 007–008, TLS gateway config, Compose/Makefile tooling, and compatibility evidence - Tighten .gitignore for macOS, hidden directories (.*/), and local secrets
