Six functions have no caller anywhere in the template, the source project or any of the three library variants — confirmed by two independent search strategies: ipc_sensorhub_ble_connected, ipc_sensorhub_feed_bmi270, ipc_sensorhub_feed_bmm350, ipc_sensorhub_get_time_str, ui_widget_mgr_needs_container and ui_widget_mgr_count (the last reclassified in the pin-extraction pass: its only hits are its declaration and three definitions). Their examples are authored for the documentation, labelled as such, and the docs build compiles them against these headers before rendering; the authored example file is a documentation-build input, not part of this package.
