Forms Processing and Updating — Proof of Concept

Technical prototype portfolio — demonstration environment

Runs against the bundled sample PDF form below with bundled update instructions, some deliberately wrong. No AI step — every real field name, type, and current value is read directly from the PDF's own AcroForm; an update instruction naming a field that doesn't really exist, or selecting an option a dropdown doesn't really have, is caught and skipped rather than silently written — pdf-lib itself doesn't reject an out-of-list option, so that check is done by hand against the field's own real option list. Every applied update is then independently re-verified by reloading the real saved output from scratch, and every untouched field is confirmed to have genuinely stayed unchanged. Do not submit personal, confidential or client-owned information — this public demo only runs the bundled sample below. Contact Chrisian to discuss a controlled evaluation.
