Phionyx: A Deterministic AI Runtime Architecture with Structured State Management and Pre-Response Governance
Short summary
Phionyx is a deterministic AI runtime architecture that treats LLM outputs as noisy sensor measurements rather than direct decisions, enforcing reproducible behavior through structured state vectors and a 46-block evaluation pipeline. It integrates pre-response safety control and a semantic time-based memory system with impact-weighted cache eviction. Experiments show ~31% computational overhead reduction vs post-hoc filtering and up to 24% improvement in high-value data retention vs LRU, though generalization to distributed deployments remains future work.
