     Creates a vector store for testing and automatically cleans it up.
 
-    This fixture creates a vector store, yields it to the test,
-    and ensures it's deleted after the test completes (whether it passes or fails).
+    You can have example documents ingested into the store automatically by passing a
+    non-empty ``doc_sources`` list in the indirect parametrization dict (URLs, files, or
+    directories under the repo root). Omit ``doc_sources`` when the test only needs an
+    empty store.
+
+    Options when parametrizing with ``indirect=True``:
+
+    * ``vector_io_provider`` (optional): backend id for the store; defaults to ``"milvus"``.
+    * ``doc_sources`` (optional): non-empty list of document sources to upload after creation.
+      Omitted, empty, or absent means no uploads. Each entry may be:
+
+      * A remote URL (``http://`` or ``https://``)
+      * A repo-relative or absolute file path
+      * A directory path (all files in the directory are uploaded)

+# Llama Stack test fixtures (internal)
+
+These files are for **internal Open Data Hub / OpenShift AI integration tests** only. We use them to hit **[Llama Stack](https://github.com/meta-llama/llama-stack) vector store APIs**—think ingest, indexing, search, and the plumbing around that—not as a shipped dataset or for model training.
+
+## IBM finance PDFs (`corpus/finance/`)
+
+The PDFs here are IBM **quarterly earnings press releases** (the same material IBM posts for investors). If you need to replace or refresh them, download the official PDFs from IBM’s site:
+
+[Quarterly earnings announcements](https://www.ibm.com/investor/financial-reporting/quarterly-earnings) (choose year and quarter, then open the press release PDF).
+
+## PDF edge cases (`corpus/pdf-testing/`)
+
+This folder is for **weird PDFs on purpose**: password-protected files, digitally signed ones (e.g. PAdES), and similar cases so we can test how ingestion and parsers behave when the file is not a plain “print to PDF” document.
+
+## Small print
+
+Not for external distribution as a “dataset.” PDFs stay under their publishers’ terms; don’t reuse them outside this test context without checking those terms.
