# Codecov is REPORTING, not a gate. The enforced coverage rules live in
# coverage-thresholds.json and are applied by .azurepipelines/check-coverage.ps1
# inside the pipeline, where they can react to how much a patch actually
# changed. Codecov is kept for what it is genuinely better at: the pull-request
# comment, the file-by-file diff view and the coverage trend over time.
#
# Both status checks are therefore `informational: true`. They post a status so
# the number is visible, but they never fail and must never be added to the
# branch ruleset - two gates with two sets of thresholds would sooner or later
# disagree about the same pull request, and the one that is easier to silence
# would win. Flip `informational` to false only if you also retire the
# in-pipeline patch gate.
#
# The upload itself is optional and is skipped when the CODECOV_TOKEN secret
# is absent (as it is on fork pull requests). See `ENABLE_CODECOV` in
# .github/workflows/buildandtest.yml.
