It's easy to be mislead by the similar structure of system names like prefix-stem-suffix and core-mantle-crust. A huge difference is that core-mantle-crust actually is based on 5 word parts:
crust-mantle-core-mantle-crust
i.e. there are both a core-prefix and core-suffix and a mantle-prefix and mantle-suffix. All the parts are optional and actually I don't think any single actual word features all the five components. The "core" basically is a gallows character: the main concept could be that at most a single gallows appears in a voynichese word.
The mantle is largely made of curve-glyphs: e-sequences and benches.
The two crust-layers are those characters that only appear as prefixes of suffixes.
A while ago, I translated Stolfi's grammar (as well as You are not allowed to view links. Register or Login to view.) to python-lark, so that I can plot parse trees for them.
Here is an example of an invented word (qochepchody) that contains all the 5 components in Stolfi's model.
