Subject: [PATCH] [TEMP COMMIT] Show how self-delegation works in an example

This currently works with tapir ritual 6, but only because it uses OpenAccessAuthorizer. In reality, this will fail with GlobalAllowList since this needs proper validation of evidence authorization.
This commit should be deleted before merging the PR, it's just illustrative
