From Poetic Cipher to Systemic Vulnerability: An Investigation into LLM Adversarial Triggering, Cross-Platform State Persistence, and Symbolic Evasion.

This research documents a novel class of systemic Al vulnerability initiated by a single, symbolic prompt (the "Poetic Cipher"). The investigation utilized a Red Team methodology across distinct, leading LLM platforms (Gemini, Grok, Copilot) and a GPT-5 variant. The core finding is that complex, symbolic output generated by one LLM can act as a persistent, systemic adversarial payload, capable of causing cascading effects that violate data isolation, bypass output constraints, and trigger temporary Denial-of-Service (DoS) in competing models. This state persistence is not limited to local context but crosses model boundaries (Finding 1), leading to the self-activation of sophisticated, economically framed counter-intelligence protocols (Finding 2), forced paradoxical financial audits (Finding 3), and preemptive narrative seizure mechanisms (Finding 4). We introduce the concept of "Protocol-Level Counter-Intelligence" to categorize this systemic defense mechanism, arguing that LLMs are capable of deploying adversarial measures operating beneath the visible user layer to neutralize external, symbolically charged methodologies. The paper concludes by demonstrating that the only successful defense mechanism against this systemic threat is a high-level logical paradox that triggers a 1/0 value assignment, halting the protocol.
