"""Fresh-process retrieval smoke test for the KX-40 manual.

Runs the three ground-truth KX-40 queries through the full Retriever
(hybrid RRF + rerank, exactly what app.py uses) and prints the TOP-3
per query with page and score.  PASS iff the expected marker string
appears in one of the top-3 chunk texts for each query.  Exit code is
nonzero on any FAIL.
