* Inheritance Assembly

  Inheritance Assembly consists in filling current model empty fields with values taken from parent model.
  It is done in <<<InheritanceAssembler>>> ({{{./apidocs/org/apache/maven/model/inheritance/InheritanceAssembler.html}javadoc}}),
  with its <<<DefaultInheritanceAssembler>>> implementation
  ({{{./xref/org/apache/maven/model/inheritance/DefaultInheritanceAssembler.html}source}}).

    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
     |
    <mirror>
      <id>mirrorId</id>
      <mirrorOf>repositoryId</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>

But in most of the cases where we need to do something like this, we want the model just to **filter/remove** some of the data as in this example.

And in those cases, we can use classes and inheritance to take advantage of function **type annotations** to get better support in the editor and tools, and still get the FastAPI **data filtering**.

  @CanIgnoreReturnValue
  @Deprecated
  @Override
  @DoNotCall("Always throws UnsupportedOperationException")
  // DoNotCall wants this to be final, but we want to override it to return more specific types.
  // Inheritance is closed, and all subtypes are @DoNotCall, so this is safe to suppress.
  @SuppressWarnings("DoNotCall")
  public ImmutableCollection<V> removeAll(@CheckForNull Object key) {
    throw new UnsupportedOperationException();

And any model class that doesn't have `table=True` is a **data model**, these ones are actually just Pydantic models (with a couple of small extra features). 🤓

With SQLModel, we can use **inheritance** to **avoid duplicating** all the fields in all the cases.

#### `HeroBase` - the base class

Let's start with a `HeroBase` model that has all the **fields that are shared** by all the models:

* `name`
