in the YP dev manual, section 3.1.6, there is a maddeningly vague
note:

"It is possible for a recipe with a lower version number PV in a layer
that has a higher priority to take precedence."

so does it take precedence or not? just saying it's "possible"
doesn't clarify it for the reader.

Yes, this should be re-worded. This is actually a FAQ.
(I remember more sentences like this exist, that especially for
non-English speakers might be difficult to interpret.)

My proposal would be:

If a recipe exists in multiple layers, the recipe with highest PV
*from the layer with the highest priority* is selected.
Be aware that recipes with the same PN in lower priority layers are
thus not selected, *even if their PV is higher*.

Leon.
