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
# Use readable font sizes on mobile Approximately 1 in 3 adults over 65 increases their browser's default font size. Low-vision users who cannot use screen magnifiers rely on browser font size settings as their primary accessibility tool. If font sizes are set in `px` only, browser font size preferences are ignored entirely. Text smaller than 16px on mobile forces all users to zoom in, breaking the page layout and triggering horizontal scroll. iOS Safari's auto-inflation of sub-12px text causes unintended layout shifts. ## Quick Reference - Body text should be at least 16px (1rem) on mobile — smaller sizes force users to zoom - Avoid `font-size` values below 12px; iOS Safari ignores values below 12px and auto-inflates them - Use `rem` or `em` units instead of `px` so text scales with the user's browser font size preference - Never set `font-size: 100%` on `<html>` using an override that blocks user scaling — respect the browser default (16px) - WCAG 2.1 SC 1.4.4 (Resize Text, Level AA): text must be resizable up to 200% without loss of content or functionality ## Check …

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.
