<DEVELOPMENT_RUBRIC>
| Category | Description | A | B | C | D | F |
|---|---|---|---|---|---|---|
| Code Architecture | Weight: 1x | Exceptional architecture with perfect separation of concerns, SOLID principles, and maintainable patterns that scale effortlessly. | Well-structured code with clear architectural patterns; minor improvements could further enhance maintainability. | Functional architecture with basic separation, though some components mix responsibilities or duplicate logic. | Some architectural patterns present but significant refactoring needed; tight coupling between components. | No discernible architecture; spaghetti code with global state, tight coupling, and unmaintainable complexity. |
| Performance | Weight: 1x | Lightning-fast app with optimized rendering, efficient memory usage, and no frame drops even on low-end devices. | Good performance across most use cases with only occasional optimization opportunities in complex scenarios. | Acceptable performance for typical usage, though complex operations cause noticeable lag or memory issues. | Performance issues affect core functionality; frequent frame drops or slow load times on medium-spec devices. | Critically poor performance; app freezes regularly, crashes under normal use, or consumes excessive resources. |
| UI Implementation | Weight: 1x | Pixel-perfect implementation matching designs with flawless animations, responsive layouts, and perfect platform adaptation. | UI closely matches designs with smooth transitions; minor inconsistencies in complex components or edge cases. | Core UI elements implemented adequately but animations lack polish or complex layouts show inconsistencies. | Significant deviations from design specifications; awkward animations and unresponsive layout adaptation. | UI implementation bears little resemblance to specifications; broken layouts, missing components, and unusable on various screen sizes. |
| State Management | Weight: 1x | Sophisticated state management with predictable data flow, efficient updates, and perfect synchronization across the application. | Clear state management approach with mostly predictable patterns; occasional redundant updates or complex flows. | Functional state management for simple cases, though complex interactions cause inconsistencies or race conditions. | Problematic state handling with multiple sources of truth and frequent UI/data mismatches. | Chaotic state management with unpredictable behavior, constant state corruption, and impossible debugging. |
| Platform Compatibility | Weight: 1x | Seamless adaptation across all target platforms with perfect handling of platform nuances and hardware variations. | Good compatibility across primary platforms with appropriate handling of most platform differences. | Works on all specified platforms but with inconsistent behavior or missing platform-specific optimizations. | Functions on main platforms but with significant bugs or missing features on secondary targets. | Broken functionality on multiple target platforms; fails to handle basic platform differences. |
| Testing & Error Handling | Weight: 1x | Comprehensive test coverage with robust error handling, graceful fallbacks, and clear user-facing error messaging. | Good test coverage for critical paths with appropriate error handling in most scenarios. | Basic testing of primary features with error handling for common cases but gaps in edge scenarios. | Minimal testing with inadequate error handling; unexpected app behavior when errors occur. | No meaningful testing or error handling; crashes on unexpected inputs or network failures. |
