We present Reflex Fabric, a local SQLite-based reflex layer that enables AI agents to complete high-frequency decisions in sub-millisecond time without invoking cloud LLMs. Operating as a sub-LLM layer analogous to the cerebellum in human motor control, the system handles routine decisions locally while reserving LLM capacity for genuine reasoning. Key innovations include a six-category reflex taxonomy, a strength decay model with configurable half-life, automatic nighttime consolidation, and a hardening mechanism for permanent reflex solidification. Benchmarks show 0.0034ms average lookup time—2.4 million times faster than typical LLM routing—while maintaining full offline operability when cloud services fail.
