destroy() can drop a still-queued 401/403 write, so rejected upgrades now end() the socket after the status line. Real TCP tests cover both statuses.

Review follow-up for the remaining CodeRabbit thread. Close rejected sockets after flushing the response. Fixed. Origin and token rejection (and the upgrade catch path) now call Resolved the inline thread. Later stacked heads still throw on origin/token failure and answer 403 from the catch path; they do not have this 401 write path, so this change stays on this PR. |

Each transport starts a heartbeat interval that only clears when the WebSocketServer closes. Tests now call close() so those timers do not leak.

…ccess The TypeScript 7 package check reports TS2341 on transport.socket. Route those spies through a double assertion so the tests still cover upgrade handling.

What I did
For security reasons, the WebSocket connection was rejecting upgrade requests without an
Originheader or with an invalidOriginheader. However, for Node clients (like our attached tools CLI), anOriginheader is not sent (and doesn't make sense), so the absence of the header should be allowed as long as the security token is correct. Browsers always send theOriginheader.Also improved the closing of the connection - when the server is stopped (SIGTERM), clients are now notified.
Outline for you to rewrite:
