Demonstrates compiling a .NET CLR into a single ~8.5 MB .wasm bundle and running it outside the browser using WASI + Wasmtime host, loading a Rust-compiled module to copy /etc/hosts (fails unless directory is explicitly pre-opened), and enforces resource limits with fuel-limited execution (demo measures ~35,000 fuel consumed; runs fail when fuel is too low). Covers running inside TEEs (Anox model) and the upcoming component model for fine-grained capability sandboxing.
