## Things to Consider - We might be able to get rid of `BaseContribution` since `Partial` might have this information - `ForkedTree` contains enough information that we probably don't need the pointer logic - We can get rid of `Full` in place of `Partial` - Refactor Node/InnerNode API (we can probably get rid of it) - Let's try to unify `SentinelSource` and `InnerMap` - `InnerPath` should not have leaf information - `assert_valid_path` should only take one pointer argument, probably `index`
