control is missing a high-confidence accessible name

Why this fires¶

TE744 is a high-confidence accessibility diagnostic. It currently covers missing image alternatives and interactive controls with no accessible name.

<img src="avatar.png" />
// error[TE744]: <img> needs an alt text alternative

Fix it¶

Provide meaningful alt text, use alt="" for a decorative image, or name a control with visible text, a matching <label>, or an ARIA label.

TE744 only fires when the missing name is certain. Dynamic content such as {label}, <children />, a nested component, or an HtmlAttrs spread may provide the accessible name at runtime, so the component definition stays clean.

For a reusable control that must always receive visible text, express that in its API by making children required instead of defaulting it to empty:

fn Button(children: fn() -> View) -> View {
  <button><children /></button>
}

<Button /> // error at this call site: required children are missing

Alternatively, expose a required label: str prop and apply it with aria-label={label}. Verniz does not guess through component boundaries: a call-site diagnostic is emitted only when the component signature makes the requirement explicit.
