Most PDFs in this library are generated programmatically (reportlab + pikepdf

• Ghostscript - see the source repo if you care). A handful are imported verbatim from explicitly CC0 or public-domain sources. Each import is documented below.

irs-1040-blank.pdf

• Source: https://www.irs.gov/pub/irs-pdf/f1040.pdf
• License: US federal government work, public domain (17 U.S.C. § 105)
• Downloaded: 2026-05-12
• Format: PDF 1.7
• Notes: The IRS rotates this form annually under the same URL. If we ever re-import for a newer tax year, the existing fixture will be renamed (e.g. irs-1040-blank-2026.pdf) and a new one shipped under a new ID, per the project’s URL-immutability rule. Until then, this fixture reflects the form as it was on the download date.

Synthesized documents

The remaining document-shape fixtures (invoice, receipt, bank statement, contract NDA, lab report, fax cover sheet) are synthesized in generate/builders/documents.py with deliberately fake entities (Jane Doe, Acme Widgets Inc., Globex Corp.). They are not based on any real document.
