Combine asyncio.to_thread for CPU-bound PDF generation:

: Always timestamp signatures (adds legal timestamp server URL) – prevents rejection after cert expiry. Part III: Development Strategies for Modern Teams 7. Strategy: Isolated Environment per PDF Task – Use uv + Workspaces The Impact : No dependency hell between pypdf , pdf2image , reportlab , and PyMuPDF . Combine asyncio

def filter_keywords(stream: Iterator, keywords: set[str]) -> Iterator: for path, i, text in stream: if any(kw in text for kw in keywords): yield (path, i, text) pages = pdf_page_generator(Path("/invoices")) important = filter_keywords(pages, {"refund", "dispute"}) – Use pikepdf + xmltodict : def filter_keywords(stream:

: Use cryptography 's x509 module to load certificates from YubiHSM or cloud KMS.
