The page block was written as 1.035 of the cover, spilling past it on three
sides -- the comment above it said so plainly, and it is backwards. The
overhang is called the square and it is the entire point of a board
binding: the boards take the knocks so the leaves do not. Written the wrong
way round the model read as a ream of paper with a leather lid, which is
what it had always looked like. Flush at the spine, inset on the three free
edges, and the leather now shows around the block.
With that, the boards are also thicker. At a ninth of the book each they
came to 14 mm against 48 mm of paper; a medieval binding is oak boards
first and leather second, and they are substantial.
And the book now has its corner bosses. They are the most recognisable
thing about a book of this period and there were none. Not ornament
either: a volume this heavy was stored flat, often on its side, and the
bosses hold the leather clear of the shelf so it does not abrade -- the
same edges the square protects.
The pouch's body goes from nine sides to thirteen. Leather has no facets,
and the body is the whole silhouette of that model.
The spilled coins beside it stay. That is not a fault: the config field
says "number of coins spilled outside", so the scatter is the model's own
idea and pulling it in would be redesigning rather than fixing.
