# 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.
