pdfsys-parser-pipeline
Region-level OCR backend for scanned PDFs with simple layouts. Stub only — not yet implemented.
Will take a LayoutDocument from the cache, crop each region at the configured DPI, and run OCR (RapidOCR / PaddleOCR-classic) on each crop individually. Produces an ExtractedDoc following the same schema as parser-mupdf.
