...prefix の末尾に `/` を含めてはいけません。

この場合の prefix は `/items` です。

We should be able to simplify the rules for comparable or delegate some of them
elsewhere since we have a section that clearly defines how interfaces implement
other interfaces based on their type sets. But this should get us going for now.
