# Codecov behavior config, following the rapidsai/cudf + zarr shapes.

# Post a coverage summary comment on PRs. Kept low-noise: only when
# coverage actually changes, and only after the coverage upload(s) land.

  layout: "diff, files"
  behavior: default
  require_changes: true  # only comment when coverage changes vs base

coverage:
  status:
    # The in-repo Coverage job already gates the project total via
    # --fail-under; a second gate here would just be a duplicate.

      default:
        target: auto
        threshold: 5%        # tolerance band so small diffs don't flip status
        informational: true  # diff coverage is a signal, never a blocker

# Flags let Codecov combine partial coverage uploads correctly. The PR
# Coverage job runs a testmon-selected subset, so without carryforward a
# PR that runs only a few tests would report artificially low coverage;
# carryforward reuses the last-known coverage for anything not re-run.
