garvitv14/snowcorp-lab ? reverse-engineered prompt

Build me a local Active Directory training lab that runs on VirtualBox and Vagrant, with Ansible doing the setup. I want two domains, lab.local and corp.local, with five machines, a forest trust between the domains, and one dual homed Windows machine that acts as the bridge between the two networks. Include the three flags on the right machines, and make it easy to spin everything up from one command, then run the domain and machine provisioning after the VMs boot.

Please make the setup work on a normal Linux or macOS host, and include clear scripts or make commands for install, check, up, and orchestration. The lab should be self contained, use private internal networks, and be ready for someone to practice attacking it from a Kali box on the same VirtualBox network. If anything is unclear, look up current docs online and keep the setup reliable and repeatable.
