Background

Roadmap reference: ROADMAP.md > P2 > Backend > analyze_single_patent assumes local file path

analyze_single_patent constructs patents/{patent_id}.pdf and attempts to read it from disk, but it never downloads the PDF first. Calling it for a patent that has not been previously fetched silently fails or raises an unhandled file-not-found error.

What to do

  1. At the start of analyze_single_patent, check whether patents/{patent_id}.pdf exists on disk.
  2. If the file is absent, call the existing PDF download logic (or a dedicated download_patent_pdf(patent_id) helper) before proceeding.
  3. Handle download failures gracefully: if the PDF cannot be fetched, return a structured error (not an unhandled exception).
  4. Add a test using a mocked HTTP response that verifies the download is triggered when the file is absent.

Acceptance criteria

  • Calling analyze_single_patent for a patent with no cached PDF automatically fetches it.
  • A download failure returns a clear error response rather than an unhandled exception.
  • Existing behavior for already-cached PDFs is unchanged.

Closing: already implemented in main. analyzer.py downloads PDFs before reading from disk (line 139: 'PDF not on disk; downloading from cached link').
