    # The reports live at `<report-dir>/node-<version>-<label>/lcov.info`, one level below
    # `report-dir`, so the presence check has to recurse — a top-level-only probe finds nothing and
    # silently skips the upload, which is what starved the Datadog coverage upload. Only lcov ships:
    # both Datadog and Codecov ingest it (see `scripts/upload-coverage.mjs`).

    # The artifact name carries the grouping flag plus a per-cell suffix (`__<job>-<matrix-index>`)
    # so matrix cells that share a flag — cypress varies `spec` outside its flag — upload distinct
    # artifacts instead of clobbering each other under one name.
