sample-corpus	Analyze and maintain the PDFtoMD samples corpus. Use when Codex needs to classify samples/ PDFs, design samples/metadata.json, identify OCR candidates, or connect corpus traits to focused regression tests.

Sample Corpus

Workflow

1. Read AGENTS.md, PLAN.md, PROGRESS.md, docs/PRD.md, and docs/CONVERSION_POLICY.md.
2. Inspect PDFs with PyMuPDF before proposing tests.
3. Track these traits per PDF:
   • page count
   • text-layer quality
   • scanned or mixed pages
   • multi-column layout
   • formula density
   • table density
   • figure density
   • Korean filename/path coverage
4. If writing metadata, use samples/metadata.json and update PROGRESS.md.

Guardrails

• Preserve original sample PDFs.
• Do not rename Korean sample files unless the user explicitly asks.
• Do not treat first-page text length as the only OCR signal.
