We present Reflex Fabric, a local SQLite-backed reflex layer that operates below the LLM inference layer in AI agent architectures. Inspired by the neuroscience distinction between cortical deliberation and cerebellar motor programs, Reflex Fabric enables sub-millisecond decision execution for high-frequency agent tasks without invoking cloud LLMs. The system classifies agent behaviors into six reflex types (R/I/E/C/M/P), maintains dynamic strength scores using strength = hits / (hits + misses + 1) with configurable half-life decay, and permanently hardens high-confidence patterns via a Long-Term Potentiation analog. Benchmark results show 0.0034ms average lookup latency — a 2,400,000x speedup over LLM-based routing — with full offline availability. The system requires only Python 3.8+ and SQLite with no external dependencies.
