- Move standalone WASM host behavior behind shared kernel-owned POSIX services while retaining V8 for JavaScript and V8-WASM compatibility.
- Add production Wasmtime and isolated Wasmtime-threads selectors with bounded lifecycle, resources, cancellation, and typed errors.
- Matrix the maintained WASM, software, actor, filesystem, networking, PTY, safety, and release-artifact coverage across V8 and Wasmtime.
- Preserve V8 as the default based on recorded cold-start and retained-memory gates; keep AOT, pooling, Wizer, and live snapshots out of scope.
