+## Description
+
+Meta task that clusters NAPI tasks. Once complete, the `@alkdev/wraith` Node.js native addon provides `connect()` and `serve()` returning duplex streams for TypeScript consumers.
+
+## Acceptance Criteria
+
+- [ ] All NAPI tasks completed
+- [ ] `connect()` returns Duplex stream, no SOCKS5, no port forwarding
+- [ ] `serve()` returns WraithServer with close() and onConnection events
+- [ ] Key material from Buffer (in-memory) and file paths both work
+- [ ] JS-to-Rust and Rust-to-JS error marshalling works correctly
