THE EASY DIRECTION
Explore
Three ways in. Wander the grid, hand the library a piece of text and get back its exact coordinate, or start from somewhere already known. All three reach a page you can already describe — finding one nobody has described is the hard problem, and that lives on Finds.
Pick a bookmark by hand, byte by byte.
At the surface.
NAVIGATION · THE SHELVES
Each cell is one byte — 16 × 16, 256 branches at every depth. Descend 32 times and you have chosen one bookmark out of 2256. A bookmark is not a full address: a page is 32,000 bytes, and the 32 you pick here are expanded deterministically into all of them, so the same shelf always opens the same page. Naming a page outright takes all 32,000 bytes, which is what Search does.

these 32 bytes are a bookmark, not the page’s address: they are expanded deterministically into the full 32,000 bytes, so the same shelf always opens the same page. The address of that page is the page itself, and it is shown when you open it.
every descent narrows the world by a factor of 256
