## Overview

Again uses the
[codecov/codecov-action](https://github.com/codecov/codecov-action) to
store coverage reports, this time from `coverage-hydrate` and
`coverage-setup`.

For convenience, all coverage reports are stored in GitHub Actions
(https://docs.github.com/en/actions/using-workflows/storing-workflow-data-as-artifacts).
