Lesson 4.5
Wiring it together - hello.js and the stage checks
Move the teaching server onto the (req, res) pair, add this chapter's frozen fixture route, and run the stage-05 and stage-06 checks that prove the writer, keep-alive, and pipelining over real sockets.
What you will build
- Rewrite the example server so handlers call Response methods and never touch the socket.
- Serve the frozen GET /created fixture and confirm its status, fields, and body.
- Run the stage 05 and 06 checks and the through-6 regression.
