On the call this morning we eliminated the complex rules. While a public branch probably shouldn't be stacked on a private branch (it's unlikely to ever be done except by mistake, and the branch won't be usable unless the stacked-on is accessible), there's no reason that the information types have to match exactly. So the new rule is this: when stacked-on changes, if the new stacked-on is private but the stacked branch is public, the stacked branch inherits the stacked-on branch's information type. This probably has to propagate down through the tree, but we never need to change a private information type; we just have to ensure that any with a public information type are changed to a private one.
