 ## 🧠 Core Concepts
 
 | Module | Description | Key Concepts |
 | :--- | :--- | :--- |
-| **Reactivity** | The heart of Vue's magic | `Proxy`, `Effect`, `Dependency Tracking` |
-| **Runtime** | How Vue renders to the DOM | `Virtual DOM`, `Diff Algorithm`, `Patch` |
-| **Compiler** | Template transformation | `Parsing`, `AST`, `Code Generation` |
+| **Reactivity (Vue 2)** | The classic "Spy" system | `Object.defineProperty`, `Dep`, `Getter/Setter` |
+| **Virtual DOM** | The blueprint of UI | `VNode`, `h()`, `Object Tree` |
+| **Renderer** | Turning blueprints into reality | `Mount`, `Patch`, `Diff Algorithm` |
+| **Reactivity (Vue 3)** | The modern "Proxy" revolution | `Proxy`, `Reflect`, `Trap` |
+| **Vapor Mode** | The future: No VDOM | `Surgical Updates`, `Compile-time Optimization` |
