# WRNexusJS 0.7.0 R5 — Happy DOM element/event type alignment

## Problem

R4 returned Happy DOM `Event` objects from the test helper, but two inputs were still cast to the browser DOM `HTMLInputElement` type. TypeScript therefore rejected the Happy DOM event at `dispatchEvent()`.

## Correction

`packages/validation/test/validation.test.ts` now imports and consistently uses Happy DOM types for:

- `Event`
- `IEventInit`
- `HTMLElement`
- `HTMLInputElement`
- `HTMLFormElement`

The input, field, error and form nodes no longer use browser DOM global casts. Submit events also no longer cast back to the browser DOM `Event` type.

## Regression gate

`validate:0.7` now verifies that the validation tests use one Happy DOM type system and rejects the old `as unknown as HTMLInputElement`, `HTMLFormElement`, or `HTMLElement` casts.
