+# JD application hub
+
+The first web application running on `JD-FD-PRIMARY`. It binds only to
+`127.0.0.1:8088`; `BS-GZ-006` reaches it through a restricted persistent SSH
+tunnel and publishes it below `https://guanghulab.com/jd/`.
+
+Version 2 keeps the application page on loopback port `8088` and adds one
+`/code/` reverse-proxy boundary to the isolated HoloLake Code Channel on
+`127.0.0.1:3340`. This reuses the existing permitopen-restricted Guangzhou
+application tunnel; it does not broaden the Forgejo tunnel key or expose a new
+JD port.
+
+No server address, credential or private key belongs in this directory.
