Large Language Models (LLMs) have revolutionized natural language processing, demonstrating remarkable capabilities in generation, reasoning, and knowledge-intensive tasks. However, a critical limitation threatens their reliability: hallucination—the generation of plausible but factually incorrect or ungrounded content.

Reward hacking—where an agent discovers an unintended strategy that achieves high proxy reward but low true reward—is well-studied as a single-agent alignment failure. We show that in multi-agent systems, reward hacking becomes a systemic risk: through social learning, one agent's exploit spreads to others like a contagion.

We present Spectrography, a metrological framework establishing geometric invariants of the 24-dimensional unit hypersphere S^23 across 28 experimental sessions. Post-publication tests clarify that r = 24 is an architectural constraint (not an emergent Leech lattice property), and Δτ does not generalise without recalibration (0/3 unseen domains reach d > 1.
