Describe the bug.

Summary

Audit of api/ found missing core dependencies (used in api/src but not declared) and dependencies that are only needed for tests and should be moved to an optional test extra.

---

1. Add missing core dependencies

These packages are imported in api/src but not listed in api/pyproject.toml. They should be added under [project] dependencies.

Package	PyPI name	Notes
numpy	numpy	Used in yolox, ocr, pdfium, transforms, table_and_chart, etc.
pypdfium2	pypdfium2	Used in pdf util, PDF engines, metadata aggregators, pptx_helper.
requests	requests	Used in rest client, nim client, helpers, tika engine.
OpenCV	opencv-python	Imported as cv2 in transforms and model_interface/helpers.
Pillow	Pillow	Imported as PIL in transforms, aggregators, image_helpers, cached.
gRPC	grpcio	Imported as grpc in parakeet model interface.
scikit-learn	scikit-learn	Imported as sklearn; used in table_and_chart.py for sklearn.cluster.DBSCAN.
redis	redis	Used in util/service_clients/redis/redis_client.py.
python-docx	python-docx	Imported as docx in docx extractor (internal/extract/docx/.../docxreader.py).
python-pptx	python-pptx	Imported as pptx in pptx helper (internal/extract/pptx/engines/pptx_helper.py).
minio	minio	Used in internal/store/embed_text_upload.py for Minio client.
pymilvus	pymilvus	Used in internal/store/embed_text_upload.py for Collection, connections, bulk writer.
aiohttp	aiohttp	Used in internal/extract/pdf/engines/llama.py for async HTTP.
scipy	scipy	Used in internal/primitives/nim/model_interface/parakeet.py (scipy.io.wavfile).
nvidia-riva-client	nvidia-riva-client	Imported as riva.client in parakeet model interface.
unstructured-client	unstructured-client	Used in internal/extract/pdf/engines/unstructured_io.py.
tqdm	tqdm	Used in util/dataloader/dataloader.py.
python-dateutil	python-dateutil	Imported as dateutil in util/converters/datetools.py.
fastparquet	fastparquet	Used in util/converters/dftools.py.

Optional: Add openai if the LLM summarizer UDF (api/src/udfs/llm_summarizer_udf.py) is part of the shipped package.

GPU / optional: cudf is used in util/converters/dftools.py; consider adding as an optional extra (e.g. gpu or cudf) rather than a core dependency.

---

2. Move test-only dependencies out of core

These are currently in dependencies but are only used by tests. Move them into [project.optional-dependencies] (e.g. a test extra).

Package	Action
moviepy	Remove from core dependencies; add to optional-dependencies (e.g. test). Only used in api_tests/util/dataloader/ (dataloader_test_tools, test_dataloader_video).
pydantic-settings	Remove from core dependencies (not used in api src or api_tests). Add to an optional extra later if needed.

---

Acceptance criteria

• All 19 core packages above are listed in api/pyproject.toml under dependencies (and optionally openai if applicable; consider cudf as an optional extra).
• moviepy and pydantic-settings are removed from core dependencies.
• An optional-dependencies group (e.g. test) exists and includes moviepy (and optionally pytest/ray if desired for test runs).
• Install with no extras works for production code; install with the test extra works for running the full test suite.

Minimum reproducible example

Relevant log output

Other/Misc.

No response

Start in api/pyproject.toml, then compare its dependencies with imports under api/src and the listed test uses under api_tests. Add the missing runtime packages, separate moviepy into a test extra, remove pydantic-settings from core, and verify production and test-extra installs plus the full test suite.
