Salvage damaged or truncated PDFs

Broken headers, missing end-of-file markers and truncated downloads are rebuilt where possible, readable pages are salvaged into a fresh file, and a JSON report shows exactly what was fixed and what was lost.

Private by design

Broken structures rebuild on this device with nothing sent out. Court filings and archived scans stay local while readable pages return to a fresh file.
