SHA-256 fingerprints of files that no longer change. A line is added, never edited.
Check a file: Get-FileHash <file> -Algorithm SHA256 (Windows PowerShell), or shasum -a 256 <file> (macOS),
and compare the code with this list as archived on the Wayback Machine on or after the date shown.
A match shows the file is unchanged since then; it doesn't show the file is right.
