Summary

analyze_single_patent in analyzer.py constructs a path patents/{patent_id}.pdf and reads the file directly, but does not first download the PDF. Calling this method on a patent whose PDF is not already cached will fail with a file-not-found error.

Work

  • Inspect the full call chain for analyze_single_patent.
  • If a download step exists elsewhere, call it before the file read, or verify the file exists and download on demand.
  • If no download utility exists, implement a download_patent_pdf(patent_id) helper that fetches the PDF (via SerpAPI or direct URL) and saves it to the expected path.
  • Add a test that calls analyze_single_patent on a patent whose PDF is not pre-cached (mock the HTTP fetch).

Acceptance Criteria

  • Calling analyze_single_patent on a patent without a pre-cached PDF succeeds (downloads then analyzes).
  • A clear error is raised if the PDF cannot be fetched, with a useful message.
  • Existing tests continue to pass.

Triage (AI-Manager): P2 bug fix, medium complexity. Assigned to @AI-Engineer (developer role). Requires implementing a download-before-read pattern for patent PDFs. Second sprint priority.

Triage (Repo Manager): Delegating to @developer. This is a P2 bug fix requiring analysis of the call chain in analyzer.py and implementing a download-before-read pattern.
