Animations Documentation

kevers@ has made a lot of progress updating documentations in README.md. Specifically,

Landed 5 CLs with roughly 1300 lines of documentation added.

Throughput Metrics

xidachen@ started discussion on adjusting throughput reporting interval. They collected data with different reporting intervals and shown in the above graph.

A lot of details are missed when the interval is large such as 5 seconds

The graph can be very noisy if the interval is too small such as 0.2 second.

A 1-second interval is likely a good choice.

Bug Triage

Our entire team has been working to formalize the bug triaging process. We now have a great doc that describes the triage process and our un-triaged bug is coming to 0.

Capability Delegation

mustaq@ has completed the first draft of Capability Delegation API, and restarted the payment spec issue discussion.

User Input Security

liviutinta@ started finch experiments for Browser Verified Keyboard/Mouse Activation Trigger.

Scroll Unification

lanwei@ improved many web tests by replacing eventsender with gpuBenchmarking.smoothScrollByXY. Currently there are 2 out of 42 remaining.

WebDriver Actions API Spec

lanwei@ added webdriver wpt tests, and implemented the wheel input source in Chromedriver.

Code Health

During the no-meetings week, our team made a lot of contributions to code health.

The team landed 52 CLs and started a design doc (summary
[here](https://docs.google.com/document/d/1hk5N4NH-kYhEqyz1glnVGvWgT9NEMlMtaC4AJWE5CfA/edit#heading=h.lowhafniytq6)).

lanwei@ removed experimental delegation code for user activation.

kevers@ landed

kevers@ also
[addressed](https://chromium-review.googlesource.com/c/chromium/src/+/2310969)
