"""Inline httpx MockTransport test for the reindex flow (T015 verify step).

Registry fixture: one `published` + one `delisted` listing. Asserts the
resulting memory-api calls are exactly: drop partition, then upsert the
published listing only (the delisted one is silently omitted by a
drop-then-upsert-published rebuild — contracts/catalog-index.md "reindex").

Run directly: `python indexer/tests/test_reindex_flow.py`
Or via pytest: `pytest indexer/tests/test_reindex_flow.py`
