+       As the model is trained stochastically, there is some expected minimum
+       variability in its output. This can be a UX issue when the input device
+       is moving slowly and the variability is large relative to the magnitude
+       of the motion. In these cases, it is better to inhibit the prediction,
+       rather than show noisy predictions (and there is little benefit to
+       prediction anyway).
+
+       The value for this parameter should at least be close to the maximum
+       predicted distance when the input device is held stationary (i.e. the
+       expected minimum variability), and perhaps a little larger to capture
+       the UX issue mentioned above.

+# libbufferstreams: Reactive Streams for Graphics Buffers
+
+This library is currently **experimental** and **under active development**.
+It is not production ready yet.
+
+For more information on reactive streams, please see <https://www.reactive-streams.org/>
+
+## Contributing
+
+This library is natively written in Rust and exposes a C API. If you make changes to the Rust API,
+you **must** update the C API in turn. To do so, with cbindgen installed, run:
+
+```$ ./update_include.sh```

 /**
- * This function is purely for debugging. It helps us understand where the user interaction
- * was taking place. For example, if user is touching launcher, we will see a log that user
- * started interacting with launcher. In that example, the event would go to the wallpaper as well.
- * We will see both launcher and wallpaper in that list.
- * Once the interaction with a particular set of connections starts, no new logs will be printed
- * until the set of interacted connections changes.
+ * This function is for debugging and metrics collection. It has two roles.
  *
- * The following items are skipped, to reduce the logspam:
- * ACTION_OUTSIDE: any windows that are receiving ACTION_OUTSIDE are not logged
- * ACTION_UP: any windows that receive ACTION_UP are not logged (for both keys and motions).
- * This includes situations like the soft BACK button key. When the user releases (lifts up the
- * finger) the back button, then navigation bar will inject KEYCODE_BACK with ACTION_UP.
- * Both of those ACTION_UP events would not be logged
+ * The first role is to log input interaction with windows, which helps determine what the user was
+ * interacting with. For example, if user is touching launcher, we will see an input_interaction log
+ * that user started interacting with launcher window, as well as any other window that received
+ * that gesture, such as the wallpaper or other spy windows. A new input_interaction is only logged
+ * when the set of tokens that received the event changes. It is not logged again as long as the
+ * user is interacting with the same windows.
+ *
+ * The second role is to track input device activity for metrics collection. For each input event,
+ * we report the set of UIDs that the input device interacted with to the policy. Unlike for the
+ * input_interaction logs, the device interaction is reported even when the set of interaction
+ * tokens do not change.
+ *
+ * For these purposes, we do not count ACTION_OUTSIDE, ACTION_UP and ACTION_CANCEL actions as
+ * interaction. This includes up and cancel events for both keys and motions.

 #### Workflow ####
 Add transaction traces that resulted in front end bugs along
 with the layer trace after fixing the issue. The layer trace
-can be generated by using the layertracegenerator tool. The
+can be generated by using the layertracegenerator tool. Use the
+--last-entry-only flag to generate only the last entry in the
+trace. This will keep the test data to a manageable size. The
 main goal of this test suite is to add regression tests with
 minimal effort.
