# `WardrikCore.Authorization`

A sign-in a person must finish before a call can run.

A call parks on one when `WardrikCore.Credentials.fetch/2` has no credential yet. Show the person
its `url`. Once they've signed in, resume the turn and the call runs again.

# `t`

```elixir
@type t() :: %WardrikCore.Authorization{
  credential: String.t(),
  principal: WardrikCore.Principal.t() | nil,
  url: String.t()
}
```
