normalize/2
-spec normalize(entity(), map()) ->
                   {ok, map()} | {error, error_detail()}.
```

Validate a domain-field map and normalize its scalar observations, retaining not_loaded/unavailable distinctly and deriving schema-defined values. Performs no I/O; constructors and action boundaries still validate records.

## Parameters

- `Entity` (`entity()`)
- `Input` (`map()`)
