summary
Claims that Envoy can run polyglot filters as WebAssembly modules and that those filters load dynamically without recompiling or restarting Envoy. Demo builds an AssemblyScript filter that appends a response header, uses the wasme CLI to init/build/push/deploy the module to a WebAssembly Hub registry and runs it in Envoy’s embedded v8 VM. The module loads at runtime, the header appears on responses, and the push/pull workflow mirrors container image tooling.
