A curated, trusted set of inputs with verified correct outputs, used as the measuring stick for AI quality: evaluation runs score the system against it, regressions are caught by it, and improvements are proven on it.
Because without one you are navigating by vibes, whatever your dashboards claim. A good golden dataset mixes representative cases, hard cases, and edge cases, all verified, so quality claims can be measured rather than asserted.
