## 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
