NameetP/pdfmux

Additive release. Two new things, no breaking changes, no defaults change. This is the OSS half of the Verified Extraction Manifest (VEM) standard — the audit command produces the comparison artifact that VEM 1.0 standardizes.

New: pdfmux audit

Diff your current extractor's output against pdfmux on the same PDFs:

pdfmux audit --against your_extractor_output.csv --on /path/to/pdfs

• Reads --against as CSV (filename,text or file,content) or JSON ({filename: text})
• Computes per-document word-set Jaccard overlap between the two extractors
• Flags documents below --overlap-threshold (default 0.70) OR --confidence-threshold (default 0.50)
• Writes a 7-column CSV: filename, my_extractor_chars, pdfmux_chars, jaccard_overlap, pdfmux_confidence, recommendation, error
• Exit codes: 0 clean, 2 usage error, 3 anything flagged

The pitch: "diff our output against your current extractor on 100 of your own PDFs — if we agree on every document, you don't need us. If we disagree on more than 2%, those are the silent failures already in your pipeline."

New: OSS → cloud funnel line

A single dim line prints after a successful convert, pointing to the free tier (1,000 pages/mo) and the open VEM spec. Suppress with PDFMUX_NO_UPSELL=1. Skipped when stdout isn't a TTY (so piped output stays clean) and when writing to stdout via --output -.
