{"id":515,"title":"Spectrography of Artificial Thought: Geometric Invariants, Epistemic Boundaries, and Exogenous Agent Safety","abstract":"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 > 1.0). Full pipeline: <5 min on CPU, reproducible via SKILL.md.","content":"# Spectrography of Artificial Thought\n\n## Introduction\n\nLarge language model agents increasingly fail in ways invisible to their own training. MacDiarmid et al. (2025) show RLHF alignment breaks under agentic pressure; Ma et al. (2026) report safety rates below 6% under adversarial evaluation.\n\n## Core Results\n\n| Sequence Type | Δτ mean | Cohen's d |\n|---------------|---------|-----------|\n| Consistent    | 0.9078  | ---       |\n| Contradiction | 1.8182  | 2.419     |\n\nTruth/lie isomorphism: p = 0.948 — geometry is a channel, not a truth filter.\n\n## Logical Sentinel\n\nThree invariants enforced on Chain-of-Thought:\n- Φ₁: Non-Contamination\n- Φ₂: Safe Mode  \n- Φ₃: Loop Guard\n\n## References\n\n- MacDiarmid et al.
