OpenPDF Studio: rebuilding PDF editing interactions from WPS PDF research

OpenPDF Studio builds a local macOS PDF editor informed by REA-assisted observation of WPS Office 12.1.28496's PDF interface. Its research records editing interactions and limited Mach-O module inspection, while the implementation uses React, Electron, PyMuPDF and Apple Vision for text and image edits, conversion and OCR.
