| """pdfsys-router — two-stage routing for the pdfsys extraction pipeline. | |
| Stage A (cheap): classify text-ok vs needs-ocr from PyMuPDF features, using | |
| a ported FinePDFs XGBoost classifier over 124 hand-crafted features. | |
| Stage B (uses layout cache): for needs-ocr, read the LayoutDocument written | |
| by pdfsys-layout-analyser and decide pipeline vs vlm based on whether | |
| complex regions (tables / formulas) exist. Stage B is not in the MVP. | |
