Unit 20 · Language valence: C# under policy · g12b

Okay, gut reaction: **Massive undertaking. Potentially a nightmare, but doable with *very* careful architecture and a lot of discipline.** C# is a good choice for the core, but the complexity demands a layered, modular approach. **Top 3 Technical Risks:** 1. **Async Hell & UI Responsiveness:** Managing unpredictable async operations across desktop & mobile, ensuring a smooth UI, and avoiding deadlocks/starvation is *the* biggest challenge. Requires robust error handling, cancellation tokens, and potentially reactive programming (Rx.NET) to manage the data flow. 2. **3D Viewport Performance & Cross-Platform Compatibility:** Getting a performant, consistent 3D viewport across desktop (OpenGL/DirectX) and mobile (Metal/OpenGL ES) in C# is tough. Consider a well-established 3D engine wrapper (e.g., Unity, but that adds a dependency) or a very carefully optimized custom solution. 3. **Plugin Architecture Security & Stability:** Allowing end-user plugins introduces significant security risks (code (greedy generation)

Okay, Linux containers and 120fps on mid-range Android *significantly* changes the landscape. The plugin scriptability adds another layer of complexity. **What Breaks First (Likely Order):** 1. **3D Viewport Performance (Android):** 120fps on mid-range Android is *brutal*. This is the most likely to fail first, and repeatedly. Android's GPU variability and power constraints are killers. 2. **Plugin Scripting Security/Stability:** End-user scriptability is a huge attack surface. Expect exploits, crashes, and unpredictable behavior *immediately*. 3. **Async API Integration & UI Responsiveness (Mobile):** While already a risk, the mobile environment's limited resources and battery life will amplify the challenges of managing asynchronous operations and keeping the UI responsive. Desktop will likely be *relatively* stable here. 4. **Cross-Platform Consistency (Minor, but persistent):** Subtle differences in UI rendering, file system access, and even basic OS behavior will require constant vigilance.
