"""Tests for ``fetch_dc`` waterfall building blocks.
Covers the per-query helpers and the manifest writer. Doesn't drive the
full 5-wave waterfall (that's exercised live and the orchestration is
linear over the small per-query helpers tested here).
- ``_classify_session_shape`` pure
- ``_fetch`` HTTP + storage.save side effects
- ``_fetch_empty`` no-HTTP record-only
- ``_write_manifest`` on-disk JSON shape
"""
