with simple tests before moving on to the more complex and subtle failure modes
that can emerge in an asynchronous, high-concurrency system.

Code coverage is measured with `cargo tarpaulin`. The CI workflow uploads the
generated `lcov.info` report to Codecov using a pinned version of the Codecov
GitHub Action (`18283e04ce6e62d37312384ff67231eb8fd56d24`, corresponding to
v5.4.3) to make coverage visible across pull requests.
Code coverage is measured with `cargo llvm-cov`. The `ratchet-coverage` action
builds on this tool—not `cargo-tarpaulin`—and fails if coverage drops. The
resulting `lcov.info` is uploaded to Codecov using a pinned version of the
Codecov GitHub Action (`18283e04ce6e62d37312384ff67231eb8fd56d24`, corresponding
to v5.4.3). The same report is also sent to CodeScene via the
`upload-codescene-coverage@v1.2.0` action.
