`port: 0` already bound an ephemeral port at the socket level, but `this.port` stayed 0: the banner printed `:0`, CODEMAN_API_URL pointed panes at `:0`, the docker bridge listener and the unauthenticated-bind warnings read 0, and the route context's `port` was a by-value snapshot taken in setupRoutes(), before listen() runs, so `tunnelManager.start(ctx.port, …)` would have been handed 0. - After `app.listen()`, `this.port` takes the number from `this.app.server.address()` (string/null addresses are left alone). - The route context exposes `port` as a getter, and the cron routes get only the `cron` their CronPort declares instead of a spread copy of the context. - `get boundPort()`: the readonly accessor tests use instead of a private field. test/webserver-bound-port.test.ts compares each reader against the socket's own `address().port`; all three tests fail with only the write-back removed.
