The CodeQL Action is written in TypeScript and compiled to JavaScript. Both the TypeScript sources and the**generated** JavaScript code are contained in this repository. The TypeScript sources are contained in the`src` directory and the JavaScript code is contained in the`lib` directory. A GitHub Actions workflow checks that the JavaScript code in`lib` is up-to-date. Therefore, you should not review any changes to the contents of the`lib` folder and it is expected that the JavaScript code in`lib` closely mirrors the TypeScript code it is generated from.

GitHub Actions workflows in the`.github/workflows` directory whose filenames start with two underscores (e.g.`__all-platform-bundle.yml`) are automatically generated using the`pr-checks/sync.sh` script from template files in the`pr-checks/checks` directory. Therefore, you do not need to review files in the`.github/workflows` directory that starts with two underscores. However, you should review changes to the`pr-checks` directory as well as workflows in the`.github/workflows` directory that do not start with underscores.
