**Reality Check**: The complete Brain AI Rust system cannot run in Hugging Face Spaces due to:

1. **Resource Constraints**: 38+ agents need significant compute
2. **Rust Compilation**: Complex multi-crate workspace requires build environment
3. **Memory Requirements**: Real neural networks need substantial RAM
4. **Container Limits**: HF Spaces has strict boundaries

**Truth**: This demonstrates infrastructure limitations rather than providing fake responses.

**Real Brain AI Capabilities** (requires dedicated deployment):
- #3 global ranking on Humanity's Last Exam  
- 100% HumanEval success with AlgorithmCoder
- 38+ specialized cognitive agents
- Production Rust architecture with 12 crates
- Real neural network inference
