# Form.FormState

Hydrated RefSubject carrying form state plus runtime schema metadata.

## Signatures

```ts
export type FormState<Values extends object> = RefSubject.HydratedRefSubject<State<Values>, Schema.SchemaError> & {
    readonly id: string;
    readonly codec: Schema.Codec<Values, unknown>;
    readonly fields: Readonly<Record<keyof Values & string, Schema.Codec<any, any>>>;
};
```

## Property: codec

Runtime-only validation codec; it is deliberately absent from hydration state.

## Property: fields

Runtime field codecs used for field-level validation.

## Property: id

Runtime identity used to scope field/error relationships. Pass an id for deterministic SSR.
