+/**
+ * This class handles the rotation animation when the device is rotated.
+ *
+ * <p>
+ * The screen rotation animation is composed of 4 different part:
+ * <ul>
+ * <li> The screenshot: <p>
+ *     A screenshot of the whole screen prior the change of orientation is taken to hide the
+ *     element resizing below. The screenshot is then animated to rotate and cross-fade to
+ *     the new orientation with the content in the new orientation.
+ *
+ * <li> The windows on the display: <p>y
+ *      Once the device is rotated, the screen and its content are in the new orientation. The
+ *      animation first rotate the new content into the old orientation to then be able to
+ *      animate to the new orientation
+ *
+ * <li> The Background color frame: <p>
+ *      To have the animation seem more seamless, we add a color transitioning background behind the
+ *      exiting and entering layouts. We compute the brightness of the start and end
+ *      layouts and transition from the two brightness values as grayscale underneath the animation
+ *
+ * <li> The entering Blackframe: <p>

 /**
  * Test Pip Stack in bounds after rotations.

  * To run this test: `atest WMShellFlickerTests:PipRotationTest`
+ *
+ * Actions:
+ *     Launch a [pipApp] in pip mode
+ *     Launch another app [fixedApp] (appears below pip)
+ *     Rotate the screen from [testSpec.config.startRotation] to [testSpec.config.endRotation]
+ *     (usually, 0->90 and 90->0)
+ *
+ * Notes:
+ *     1. Some default assertions (e.g., nav bar, status bar and screen covered)
+ *        are inherited from [PipTransition]
+ *     2. Part of the test setup occurs automatically via
+ *        [com.android.server.wm.flicker.TransitionRunnerWithRules],
+ *        including configuring navigation mode, initial orientation and ensuring no
+ *        apps are running before setup

+# Keyguard (aka Lockscreen)
+
+Keyguard is responsible for:
+
+1. Handling authentication to allow the user to unlock the device, via biometrics or [KeyguardBouncer][1]
+2. Displaying informational content such as the time, notifications, and smartspace
+3. Always-on Display (AOD)
+
+Keyguard is the first screen available when turning on the device, as long as the user has not specified a security method of NONE.
+
+## Critical User Journeys
+
+The journeys below generally refer to Keyguard's portion of the overall flow, especially regarding use of the power button. Power button key interpretation (short press, long press, very long press, multi press) is done in [PhoneWindowManager][4], with calls to [PowerManagerService][2] to sleep or wake up, if needed.
+
+### Power On - AOD enabled or disabled
+
+Begins with the device in low power mode, with the display active for [AOD][3] or inactive. [PowerManagerService][2] can be directed to wake up on various user-configurable signals, such as lift to wake, screen taps, among others. [AOD][2], whether visibly enabled or not, handles these signals to transition AOD to full Lockscreen content. See more in [AOD][3].
+
+### Power Off
+
+An indication to power off the device most likely comes from one of two signals: the user presses the power button or the screen timeout has passed. This may [lock the device](#How-the-device-locks)
+
+#### On Lockscreen
+
+#### On Lockscreen, occluded by an activity
+
+#### Device unlocked, Keyguard has gone away
+
+### Pulsing (Incoming notifications while dozing)
+
+### How the device locks
+
+More coming
+* Screen timeout
+* Smart lock
+* Device policy
+* Power button instantly locks setting
+* Lock timeout after screen timeout setting

+# Bouncer
+
+[KeyguardBouncer][1] is the component responsible for displaying the security method set by the user (password, PIN, pattern) as well as SIM-related security methods, allowing the user to unlock the device or SIM.
+
+## Components
+
+The bouncer contains a hierarchy of controllers/views to render the user's security method and to manage the authentication attempts.
+
+1. [KeyguardBouncer][1] - Entrypoint for managing the bouncer visibility.
+    1. [KeyguardHostViewController][2] - Intercepts media keys. Can most likely be merged with the next item.
+        1. [KeyguardSecurityContainerController][3] - Manages unlock attempt responses, one-handed use
+            1. [KeyguardSecurityViewFlipperController][4] - Based upon the [KeyguardSecurityModel#SecurityMode][5], will instantiate the required view and controller. PIN, Pattern, etc.

 /**
- * Wrapper around SensorManager customized for the Proximity sensor.
- *
- * The ProximitySensor supports the concept of a primary and a
- * secondary hardware sensor. The primary sensor is used for a first
- * pass check if the phone covered. When triggered, it then checks
- * the secondary sensor for confirmation (if there is one). It does
- * not send a proximity event until the secondary sensor confirms (or
- * rejects) the reading. The secondary sensor is, in fact, the source
- * of truth.
- *
- * This is necessary as sometimes keeping the secondary sensor on for
- * extends periods is undesirable. It may, however, result in increased
- * latency for proximity readings.
- *
- * Phones should configure this via a config.xml overlay. If no
- * proximity sensor is set (primary or secondary) we fall back to the
- * default Sensor.TYPE_PROXIMITY. If proximity_sensor_type is set in
- * config.xml, that will be used as the primary sensor. If
- * proximity_sensor_secondary_type is set, that will function as the
- * secondary sensor. If no secondary is set, only the primary will be
- * used.
+ * Wrapper class for a dual ProximitySensor which supports a secondary sensor gated upon the
+ * primary).
