scrub

description

Local offline hygiene for media and documents the user owns. Strips EXIF/IPTC/XMP, best-effort C2PA/JUMBF, hidden Unicode (zero-width, bidi, tag chars), and document properties in PDF/DOCX/ODT/HTML/SVG/Markdown; optional spectral disruption for images/video/audio. Use when the user asks to scrub, clean metadata, strip C2PA, Content Credentials, EXIF, hidden Unicode, AI marks, SynthID-class research transforms, or inspect provenance on files they have rights to modify.

Scrub

Run the repo CLI. Do not upload files. Do not claim a detector will fail.

Rules

• Only process files the user owns or has explicit rights to modify.
• Originals stay untouched; outputs use a _clean suffix.
• Say best-effort / degrade / strip tags — never “guaranteed bypass” or “undetectable.”
• Statistical (token-sampling) text watermarks are out of scope. Unicode hygiene is not a paraphrase rewrite.

Commands

From the Scrub repo root (prefer .venv/bin/python if present):

python cli.py inspect PATH
python cli.py clean PATH -o OUTPUT_DIR
python cli.py clean PATH -o OUTPUT_DIR --metadata-only

Input	What clean does
.jpg .png .webp .heic …	Metadata + optional spectral/spatial chain
.mp4 .mov .wav .mp3 …	ffmpeg remux/re-encode, drop tags; optional spectral on short video
.md .txt .html .svg	Hidden Unicode + obvious generator/C2PA-ish meta
.docx .odt	Core/app props + XML text hygiene
.pdf	Info/XMP via pypdf or exiftool when installed

Workflow

1. Confirm the path and that the user wants a copy, not in-place overwrite.
2. inspect first if they asked what is in the file.
3. clean with --metadata-only unless they asked for image/video signal disruption.
4. Show the output path and quote the CLI detail line. Offer NOTICE.md if they ask about legality.
