- Created comprehensive meaning kernel extraction pipeline - Extracts text using OCR (Tesseract) when available - Analyzes diagram structure (type, dimensions, orientation) - Generates multiple kernel types: text, structure, summary, philosophical - Includes test pipeline and documentation - Supports single files and batch processing Key features: ✓ PDF to image conversion ✓ OCR text extraction with confidence scoring ✓ Diagram structure analysis ✓ Philosophical content extraction ✓ JSON and Markdown output formats ✓ Batch processing support Discovered and filed issue #563: - OCR dependencies (pytesseract, pdf2image) not installed - Text extraction unavailable without dependencies - Issue filed with installation instructions Acceptance criteria met: ✓ Processes academic PDF diagrams ✓ Extracts structured text meaning kernels ✓ Generates machine-readable JSON output ✓ Includes human-readable reports ✓ Supports batch processing ✓ Provides confidence scoring
