the worktree is in an unstable state, and not all the data added has
been integrated into the stable code. i was pursuing doing that
integration. work was invested in added things that would otherwise be
lost.

that's happened a few times already, though.

i came up with an approach that is a little simpler to think about,
where storage objects are added to the wrapping flat_tree class but
not the smaller append class. this provides for the option of
separating the index structure.
