+- Session lifecycle (create -> chat -> export -> delete)
+- Document management and session-document attachment workflows
+- SSE streaming response format validation
+- Concurrent access patterns
+- Edge cases (unicode, large payloads, malformed input)
+- System status endpoint with mocked backends
+- CLI --ui flag integration
+- Database persistence and thread safety

+"""Integration tests for GAIA Agent UI folder indexing and document lifecycle.
+
+Tests the following endpoints through the HTTP API layer:
+- POST /api/documents/index-folder -- bulk index all files in a folder
+- GET /api/documents/monitor/status -- document file monitor status
+- GET /api/documents/{doc_id}/status -- per-document indexing status
+- POST /api/documents/{doc_id}/cancel -- cancel background indexing
+- Full document lifecycle (upload -> list -> attach -> detach -> delete)
+
+LLM/RAG calls are mocked via ``gaia.ui.server._index_document`` so
+the tests run without a Lemonade server. Temporary files are created
+inside ``Path.home() / ".gaia" / "test_temp"`` to satisfy the
+``ensure_within_home`` security check.
