- The matrix reads up to 64 bytes per page, and the bit-change view marks SHA-256 differences with copper bridges.
Field notes
The bit-change view compares SHA-256 hashes before and after flipping the low bit of the first input byte; copper bridges mark exact differences. The matrix reads up to 64 bytes per page, left to right then back to front, and the tree gives repeated byte values a shared leaf. The page says messages and non-exportable keys remain in the browser tab.
