Ten of the thirty have no caller outside the archive itself (or none anywhere): g_tesaiot_display_diag, wifi_saved_load, deepcraft_task_request, rtos_cm55_gfx_task_handle, deepcraft_task_init, deepcraft_task_watchdog, tesaiot_display_task, wifi_saved_store, deepcraft_task_select, wifi_saved_count. 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. Several are anti-examples: the entry says what to call instead.
