 Manual Slop solves a single tension: **AI reasoning is high-latency and non-deterministic; GUI interaction must be low-latency and responsive.** The engine enforces strict decoupling between three thread domains so that multi-second LLM calls never block the render loop, and every AI-generated payload passes through a human-auditable gate before execution.
 
+## Project Structure

+The codebase is organized into a `src/` layout to separate implementation from configuration and artifacts.
