Test Artifact Files

  1. notes/bf-3j4ec-json-output.txt - Full JSON extraction output
  2. notes/bf-3j4ec-ndjson-output.txt - NDJSON format output (empty file)
  3. notes/bf-3j4ec-text-output.txt - Plain text output (empty file)
  4. notes/bf-3j4ec-detailed-output.txt - RUST_LOG diagnostic output (empty file)
  5. notes/bf-3j4ec.md - This verification note

Notes

  • The no-mapping.pdf fixture appears to be a minimal or edge-case PDF that parses successfully but contains no extractable content
  • No diagnostic log messages were produced even with RUST_LOG=info, suggesting clean execution path
  • The fixture is suitable for testing pdftract's handling of PDFs with no text/structure content
  • All output formats (JSON, NDJSON, text) produced consistent results
