+## Milestone Recap: Tasks 1–4
+*   **Task 1 (Material Color)**: Handled color changes imperative (Vanilla), declarative (R3F), and UI-driven (Thob).
+*   **Task 2 (Texture Mapping)**: Successfully applied checkerboard and URL-based textures. **Thob speed was the highlight here.**
+*   **Task 3 (Hover Feedback)**: Identified a **major gap**—Hover is standard in code but missing from the builder UI.
+*   **Task 4 (Click Toggle)**: Discovered that the `onClick` interaction engine is currently **unstable/broken** in the builder.
+

+
+## Top Reflections
+
+### Speed vs. Control
+*   **The Thob Advantage**: Setting up a 3D scene (adding a cube + lighting + texture) in the builder is **lightning-fast**. What takes a 10-minute Vite setup in Vanilla takes **2 minutes** in the Thob UI.
+*   **The Interactivity Threshold**: As soon as we moved from "Static Visuals" to "Interactive Behavior," the strength shifted back to **R3F**. The builder's UI for interactions exists, but the execution logic isn't there yet.
+
+### Declarative vs. Imperative
+*   Writing the **Raycaster** manually in Vanilla felt outdated and boilerplate-heavy compared to the clean **`onPointerOver`** props in R3F. 
+*   **Insight**: Thob would benefit immensely by mirroring R3F's declarative event model (simple triggers linked to property changes).
+
+---
+
+## Critical Discoveries (The "Interaction Blackout")
+The most valuable part of this week's sprint was identifying that:
+1.  **Hover (PointerOver/Out)**: Is not just "hidden"—it's currently missing as a first-class feature in the Thob engine.
+2.  **Click (Interaction Dispatcher)**: Is unreliable. Even when wired correctly in the UI, it doesn't always fire in the runtime.
+3.  **CORS/Asset Linking**: External URL textures are prone to browser blocking, making internal "Project Library" uploads the only safe path for now.
