+# Launch Build Demo
+
+This demo is the MVP build workflow expressed as Rust source code. It uses `env!("linux")`, recognizes `env!("windows")` when a Windows development node is attached, spawns debugger-visible virtual tasks, and returns artifact/source handles instead of moving large bytes through task arguments.
+
+The Linux environment is defined by `envs/linux/Containerfile`. The Windows environment is a user-attached development contract and does not claim secure managed Windows sandboxing.
+
+Inspect the bundle metadata:
+
+```bash
