+* [EVOLUTION] Component VII: The Reactive Signal Pipeline
+** Deep Reasoning: Beyond the recursive loop
+The current `cognitive-loop` is a recursive process that handles sensors and tools as distinct code paths. While functional, it is difficult to parallelize and observe. 
+- **The Circuit Board Model:** We are evolving the kernel into a functional transformation pipeline. Every event—be it a keystroke, a timer pulse, or a neural proposal—is a **Signal**.
+- **Consensus Gates:** By treating reasoning as a signal moving through a pipe, we can "split" the pipe to ask multiple LLMs simultaneously. A **Consensus Gate** later in the pipe compares the proposals and selects the most mathematically consistent one.
+- **Multi-Modal Fusion:** The pipeline can blend disparate signals (e.g. *User Prompt* + *Low Battery Alert*) into a single coherent cognitive event.
