+`UniversalBlePeripheral` exposes a local GATT-server API for apps that need to advertise services and accept central/client writes. Android, iOS, macOS, and Linux are implemented; Windows currently reports `notSupported` until its platform server implementation is added. Web browsers do not expose a standard GATT-server API.
+
+On iOS and macOS, peripheral mode uses CoreBluetooth `CBPeripheralManager`. CoreBluetooth manages CCCD subscription state internally, and central connection events are reported when a central reads, writes, subscribes, or unsubscribes from a local characteristic.
 
 On Linux, peripheral mode uses BlueZ `GattManager1` and `LEAdvertisingManager1`. The Bluetooth adapter must be powered, support the peripheral role, and the app process must be allowed to register GATT applications and LE advertisements on the system bus.
