+# share/hybbx/ — not a Lite operator path
+
+These INI examples describe **HyBBX co-host** and **TNC2C/pktnc2 hardware** attach, which are full **MAX25-Stack** features. Both are **out of scope** for MAX25-Stack-Lite (localhost `max25d` + `max25-terminal`/`max25-client`, CRDOP, BayCom/based).
+
+Kept only so the fork stays in sync with upstream `share/`; not built, not referenced by Lite's own scripts (`max25-lite-setup.sh`, `run-max25d.sh`, `run-max25-terminal.sh`), and not part of the Lite install tree.
+
+For Lite configuration, use `share/max25/max25d.lite*.ini.example` and `share/max25-bcpr/*.ini.example` instead.
