Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Adblock Element Hiding If your cookie consent banner has class `.cookie-banner` or ID `#consent-popup`, adblockers may hide it — users never see the consent notice, which can cause GDPR compliance issues and broken UX for ~30-40% of desktop users. ## Quick Reference - Adblockers use EasyList filter rules to hide elements with class names, IDs, or patterns associated with ads - Common blocked names: `.ad`, `.ads`, `.advertisement`, `.banner`, `#ad`, `#ads`, `#banner`, `.sponsor` - Affected elements: legitimate banners, notification bars, promotional sections, and cookie consent notices - Test your site with uBlock Origin enabled — check for missing content, broken layouts, or hidden consent banners - Rename affected elements using semantic, content-specific class names to avoid false-positive blocking ## Check Review the HTML source for element IDs and class names that match common adblocker patterns: .ad, .ads, .advertisement, .banner, .sponsor, #ad, #banner, .cookie-notice, .consent.

This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
