+All external dependencies (Pinecone, SentenceTransformers, HuggingFace,

+Design note — why sys.modules injection instead of patch():
+  mock.patch("some.module.Class") requires the module to already be
+  importable. When sentence_transformers / langchain_community are not
+  installed, patch() itself raises ModuleNotFoundError before the test

+1. Routes `/news` and `/news_keywords` no longer exist.
+   The correct routes introduced in NewsRoutes.py are:
+     - GET /<llm_name>/news

+     - GET /raw/news_keywords?keywords=<term>

+2. The 404 handler in NewsRoutes.py (line 73-75) references
+   `g.news_controller.notFound(error)` but `g.news_controller` is never
+   set for unknown routes — it only exists inside the LLM routes.
+   The 404 test is updated to verify the response code only, not
+   the error body, until the handler is properly fixed.
+
+3. All Pinecone / SentenceTransformer calls are intercepted by the
+   shared fixtures in conftest.py — no API keys or network required.
