Q-5-44 — book-scope Is Not a Format Option
book-scopewas set underformat:and ignored.
What this means
book-scope is read only at the top level of a metadata layer. Which format a render uses depends on the requested scope (a whole-book render uses the project’s formats), so a scope that depends on the format would be circular.
How to fix
Move book-scope out of format: to the top level of the same file.
