Only three ble_nus-family .c files ship in the template: bento_libs/claw/common/ble_nus/{bento_time.c, character_lottie.c, character_lottie_default.c}. Every other implementation (ble_nus.c, nus_events.c, nus_commands.c, ble_nus_lazy.c, radio_scheduler.c, ipc_bento_buddy_bridge.c, bento_devmode.c, nus_agent.c, sensor_stream.c, voice_capture.c, nus_protocol.c, nus_gatt_db.c, bento_fw.c, fw_hash.c, nus_base64.c, nus_folder_push.c) is archived in libbento_secure.a (16 opaque members). 77 of the 87 exported symbols have no caller anywhere in the template; where an entry cites an archived call site it says so, with the file:line in the source-of-truth tree, and never quotes it as shipped source.
