We ensure that a `rad/root` ref is included in the signed refs file under `rad/sigrefs` for all remotes. This prevents a certain kind of "grafting" attack where signed refs can be copied between repositories, by having the peer sign over the identity root together with the data refs. When verifying signed refs, we ensure that the ref is present and points to an identity branch root that matches the repository identity containing the signed refs. Alternatives: lots of alternatives were considered, but this one doesn't introduce any changes to the signing. The `rad/id/root` name was considered but is invalid due to `rad/id`.

We cannot delete a repository, since that can cause data integrity
issues. However, we can clean the storage of remotes that are not the
local peer or the repository delegates. To do this we can use the rad clean command.
First let's look at what we have locally:
$ rad ls
╭───────────────────────────────────────────────────────────────────────────────────────────────────────────╮
│ Name RID Visibility Head Description │
├───────────────────────────────────────────────────────────────────────────────────────────────────────────┤
│ heartwood rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji public f2de534 Radicle Heartwood Protocol & Stack │
╰───────────────────────────────────────────────────────────────────────────────────────────────────────────╯
Let's also inspect what remotes are in the repository:
$ rad inspect --sigrefs
z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi 99c549702e2bcfe02b0e68d4a2224fb7a1524529
z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk e9f48ef90fe8592e1b1c95f96c21a59ca1495300
Now let's clean the heartwood project:
$ rad clean rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --no-confirm
Removed z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk
✓ Successfully cleaned rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji
Inspecting the remotes again, we see that Bob is now gone:
$ rad inspect --sigrefs
z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi 99c549702e2bcfe02b0e68d4a2224fb7a1524529
Note that Bob will be fetched again if we do not untrack his node. Currently, there is no per repository tracking so it's not possible to stop fetching Bob for this particular repository.
Cleaning a repository again will remove no remotes, since we're already at the minimal set of remotes:
$ rad clean rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --no-confirm
✓ Successfully cleaned rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji
Since Eve did not fork the repository, and has no refs of their own,
when they run rad clean it will remove the project entirely:
$ rad clean rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --no-confirm
Removed z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi
✓ Successfully cleaned rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji
And attempting to clean the repository again, or any non-existent repository, has no effect on the storage at all:
$ rad clean rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --no-confirm
✗ Error: repository rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji was not found
