/**
 * A BuildService which monitors a few tasks (in both build-logic and main build) and collects information for build scan.
 * It's currently implemented by two use cases:
 * 1. Collect cache misses for compilation tasks and publish a `CACHE_MISS` tag for build scan.

## Team

There's a team of people that help manage and maintain the project. 😎

They have different levels of permissions and [specific instructions](./management-tasks.md){.internal-link target=_blank}.

Some of the tasks they can perform include:

* Adding labels to PRs.
* Editing PR titles.
* Adding commits on top of PRs to tweak them.
* Mark answers in GitHub Discussions questions, etc.
