- Created CNN milestone for CIFAR-10 training (target: 75% accuracy) - Fixed spatial.py indentation and Tensor initialization issues - Addressed memoryview problems in flatten function - Commented out problematic import-time test code - CNN architecture ready: Conv2d → MaxPool2d → Dense layers Note: Some spatial module tests still failing due to import-time execution. Clean Variable-free architecture successfully supports CNN building blocks.
