Unit tests pin the + route shape; only an end-to-end call can verify the alias_map + + vector re-embed round-trip. + 3. ``retrieval/pipeline.py:_graph_search`` cuts over to the new + vector recall. Unit tests pin the function signature; only a + real recall against an indexed graph can verify the result shape. + +The narrative is the canonical Wave 7 happy path: + + step 1: seed the lineage store with three entities (Alice / Bob / + Acme) — direct ``upsert_entity_with_lineage`` so the + narrative does not depend on a real LLM extractor's + non-deterministic output. The wiring under test is the + graph storage + vector + alias paths, not the extractor + prompt. + step 2: run the GraphIndexCompactor + vector writer phases by + invoking the per-collection ``GraphSearchService`` factory + and asserting the pre-conditions for vector recall (vectors + upserted, ``compacted_description`` populated, snapshot + diff did not delete shared entities). + step 3: call ``GraphSearchService.search_entities("Alice")`` (the + service the retrieval pipeline now routes through). Assert + hit returns Alice. Validates wiring #3 *behaviourally*. + step 4: call ``GraphService.merge_entities(target="Alice", + sources=["Alicia"])`` — the same path the REST route + ``POST /collections/{cid}/graphs/nodes/merge`` now + delegates to (per ``merge_nodes_view``). Asserts the + backward-compat response shape; HTTP layer surface is + pinned by the route unit tests. + step 5: read alias_map: assert ``{Alicia: Alice}`` persisted via + the :class:`AliasMapRepository`. + step 6: upload a NEW doc-equivalent extraction containing + ``Alicia`` through the *decorated* lineage store + (``_build_lineage_graph_store`` returns the wrapped one). + Assert that Alicia is silently redirected to Alice — no + Alicia row exists in ``aperag_lineage_entity``. This is + the critical inseparability gate proof. + step 7: search again for "Alice" → still returns the merged + entity. Vector recall on the canonical name keeps working. + step 8 (W8-3 trigger pin): ``GraphService.get_entity_detail`` + currently bypasses the alias_map on reads; calling it for + "Alicia" returns ``None`` (route emits 404).
