CG-method synthetic practice files, 2026-10-02. DEMO-SECRET-42 is a fictional test token, not personal information. source/covered: 3 pages A B C, text + metadata + demo attachment. hidden-only: no secret in page text, but token in Subject and attachment. raster-new: new PDF made only from rendered covered pages, no original text/metadata/attachment. reordered: C A B. page-b: only B. This does not certify arbitrary PDF sanitization, Acrobat or PDF24 GUI. PNGs static 8bit RGB/RGBA. Python 3.12.14/Pillow 12.3.0. From this folder run python convert-webp.py then python compare-webp.py; output must not exist. restore-test.ps1 is UTF-8 BOM and Windows PowerShell 5.1; test only ordinary local folders with no links/junctions. New output only, inputs preserved. Compare bytes+paths+empty folders, not ACL/ADS/EFS/OS/cloud restoration. Keep originals; partial failed outputs are incomplete.
