This metric operationalizes grounding as a measurable geometric quantity.</p> <p>We proceed in three stages:</p> <ol> <li><strong>Formal Definition</strong> a draft manuscript introducing Hallucination Energy, its mathematical formulation, and its role within a policy-controlled architecture.</li> <li><strong>Empirical Evaluation</strong> structured calibration and adversarial stress testing across multiple domains to assess the robustness and limits of projection-based grounding.</li> <li><strong>Applied Validation</strong> large-scale evaluation on 10,000 samples from the HaluEval summarization benchmark, demonstrating that projection-based containment functions as a strong first-order grounding signal in a real generative setting.</li> </ol> <p>This work does not claim to solve hallucination. Rather, it characterizes the boundary of projection-based grounding, establishes its suitability as a deterministic policy scalar, and documents both its strengths and its structural limitations.</p>
