LexBench-Headless-Browser

Lexbench-Headless-Browser is licensed under Apache-2.0. Some benchmark tasks and self-hosted fixtures were rewritten from Web Platform Tests (WPT), or designed with reference to Chromium inspector-protocol tests. The benchmark does not fetch or execute either upstream suite at run time; the checked-in task, fixture, and grader files are the complete runnable corpus.

This file keeps the upstream attribution and license text in one place. The paths below identify the public upstream material associated with each checked-in task.
