+// 2). this is a 'current' file. If you make a backwards compatible change to

+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.

+## Lockout
+
+Device lockout is based on the number of consecutive failed authentication attempts. There are a few
+flavors of lockout mechanisms that are supported by virtula HAL <br/>
+
+### Permanent Lockout
+
+There are two sysprop to control permanent lockout <br/>
+1. general lockout feature enable <br/>
+2. threshold of failed attempts <br/>
+`shell
+$ adb shell setprop persist.vendor.face.virtual.lockout_enable true

+
+### Temporary Lockout
+
+There are a few parameters to control temporary lockout (aka timed lockout): <br/>
+1. enable lockout (general lockout feature enable, and timed lcokout enable) <br/>
+2. threshold of failed attempts <br/>
+3. timeout in ms <br/>

+$ adb shell setprop persist.vendor.face.virtual.lockout_enable true

+$ adb shell setprop persist.vendor.face.virtual.lockout_timed_threshold 5
+$ adb shell setprop persist.vendor.face.virtual.lockout_timed_duration 10000`
+
+### Forced Lockout
+
+A permanent lockout can be inserted on next authentication attempt independent of the failed <br/>
+attempt count. This is a feature purely for test purpose.

+// type is used to build AIDL files in a way that they can be used across
