Context

analyze_single_patent constructs a path patents/{patent_id}.pdf and reads it directly from disk, but it does not trigger a download first. If the PDF is not already present the method fails. This is a silent correctness bug.

What to do

  1. Before reading the file, check whether patents/{patent_id}.pdf exists.
  2. If it does not exist, trigger the download step (reuse whatever download logic is already used elsewhere in the pipeline).
  3. If download fails, surface a meaningful error to the caller rather than a raw FileNotFoundError.
  4. Add a unit/integration test that calls analyze_single_patent for a patent whose PDF is not pre-cached and verifies it completes successfully (or fails with a descriptive error when the download source is unavailable).

Acceptance criteria

  • analyze_single_patent for an un-cached patent ID downloads the PDF automatically.
  • A missing PDF no longer raises an unhandled FileNotFoundError.
  • Test coverage exists for the download-then-analyze path.
