"""Unit tests for the submit-tab pending-row builder.

C4 contract: ``_build_pending_row`` defaults the three Bundle 1+2
schema fields (``validation_status="unvalidated"``,
``validation_method=None``, ``hf_username=None``) and keeps the
existing metadata + sha256 fields intact.

Hub I/O (``_resolve_data_revision`` reads from
``HfApi.dataset_info``) is monkeypatched out, so the suite has zero
network traffic.
