-1. PDF upload triggers page-aware pipeline (parse_pdf_by_page, chunk_pages, extract_page_as_pdf)
-2. DOCX upload uses old pipeline with document_id
-3. TXT upload uses old pipeline with document_id
+1. PDF upload triggers page-aware pipeline (page_number in metadata, page PDFs saved)
+2. DOCX upload uses old pipeline (no page_number in metadata)
+3. TXT upload uses old pipeline (no page_number in metadata)
4. Same-filename replacement: existing document found → old chunks + PDFs deleted
5. Same-filename replacement: no existing document → no deletion
6. Empty PDF (no pages with text) → 400 error
7. Page PDFs saved to correct directory with correct naming
8. Metadata includes page_number and chunk_file_path for PDF uploads
-9. Metadata does NOT include page_number for DOCX uploads (None)
+9. Metadata does NOT include page_number for DOCX uploads

"""Phase 4 integration test: Full per-sub-question query pipeline.
-Simulates the complete 4-stage pipeline (decompose → retrieve → filter → generate)
-using mocked services, verifying end-to-end data flow and SSE event emission.
+Uses TestClient hitting POST /api/v1/query with real ChromaDB and SQLite.
+Only the LLM (external API) is mocked.
+
+Verifies end-to-end data flow and SSE event emission through the real
+HTTP endpoint, real ChromaDB retrieval, and real SQLite services.
Key behaviours under test:
- Full pipeline with 2 sub-questions produces grouped results
- Empty decomposition falls back to original question (Decision #13)
- Single sub-question still uses ## Sub-question N format
- All chunks filtered out returns "no relevant information"
-- One sub-q with empty retrieval still produces partial answer
-
-All external services (LLM, ChromaDB) are mocked.
-Tests call ``_query_stream()`` directly via ``async for`` — no HTTP layer.
+- One sub-q with all chunks filtered out produces partial answer
