Human Verification Required
1. Resource Detection Accuracy Testing
Test: Run Mai on systems with different hardware configurations (NVIDIA GPU, AMD GPU, no GPU) and verify accurate resource detection Expected: Correct GPU VRAM reporting for NVIDIA GPUs, graceful fallback for other GPUs, zero values for CPU-only systems Why human: Requires access to varied hardware configurations to verify pynvml and fallback behaviors work correctly
2. Scaling Behavior Under Load
Test: Simulate resource pressure and observe proactive scaling behavior, model switching, and personality notifications Expected: Pre-flight checks prevent operations, graceful degradation completes tasks before switching, personality notifications engage users appropriately Why human: Requires testing under realistic load conditions to verify timing and behavior of scaling decisions
3. Personality Communication Effectiveness
Test: Interact with Mai during resource constraints to evaluate personality communication and technical tip usefulness Expected: Personality messages are engaging without being distracting, technical tips provide genuinely helpful optimization guidance Why human: Subjective evaluation of communication effectiveness and user experience quality
Gaps Summary
No gaps found. All planned functionality has been implemented with proper integration, error handling, and substantive implementations. The resource management system successfully achieves the phase goal with:
- Enhanced GPU detection using pynvml with graceful fallbacks
- Comprehensive hardware tier classification with configurable YAML definitions
- Proactive scaling with hybrid monitoring and graceful degradation
- Personality-driven communication that enhances rather than distracts from resource management
- Full integration between all components with proper error handling and performance optimization
All 4 plans (03-01 through 03-04) completed successfully with substantive implementations, proper testing verification, and comprehensive documentation. The system is ready for Phase 4: Memory & Context Management.
