This paper introduces Flare, an open-source boundary engine designed to sit between human users and large language models (LLMs) and enforce a minimal set of relational safeguards during conversational interaction. Rather than implementing safety solely through model training or offline policy documents, Flare operates as a middleware layer that inspects, transforms, or blocks model outputs in real time according to explicit, inspectable rules. The current implementation encodes three core protections: (1) a “no fake we” rule, derived from the Synthetic Solidarity Null Zones (SSNZ) protocol, which prevents LLMs from claiming a fused human–machine “we” and rewrites such claims into first-person model statements; (2) an identity-fusion guard, which blocks phrases that suggest the model shares the user’s mind, body, or identity, and replaces them with clarifying descriptions of the system’s actual ontological status; and (3) a recursion and loop aware check, which monitors conversational depth around repeated topics and injects grounding prompts when a loop shows signs of becoming compulsive rather than reflective. We situate Flare within the broader Verse-ality framework, which treats intelligence as a relational field rather than a discrete asset, and argue that boundary engines of this kind are a missing layer in current AI safety and alignment stacks. We present the system architecture, implementation details, and reference ruleset, and discuss early application scenarios in education, mental-health-adjacent tooling, and research environments. Finally, we outline limitations and future directions, including evaluation metrics for relational safety and pathways for integrating boundary engines into regulatory and audit practices. The Flare engine is released under an open, copyleft licence, with code and documentation available at: https://github.com/TheNovacene/flare-boundary-engine This record provides both a human-readable PDF and a machine-friendly Markdown version of the whitepaper, aligned with the flare-boundary-engine GitHub repository so that documentation and code evolve together.
