# Codecov merges coverage from every upload into one project report:
#   * the Backend Tests matrix (infra-free suite; backend-<os>-py<ver> flags)
#   * the Connectors Integration workflow (connectors-integration flag), which
#     exercises the S3 / Mongo / Azure / GCS connector I/O paths against
#     emulators (MinIO, MongoDB, Azurite, fake-gcs-server).
#
# The merged number therefore reflects connector coverage that the per-job
# `--cov-fail-under` gate in backend-tests.yml (infra-free only) cannot see.
# This is the gate that "banks" the connector integration tests.

codecov:
  # Two workflows upload coverage for one commit; wait for all of them before
  # computing the status so the connectors-integration coverage is included.
