The itemize environment parameters [leftmargin=*, itemsep=1pt, parsep=0pt]
were appearing as visible text in the PDF because the enumitem package
wasn't loaded. This fix adds \usepackage{enumitem} to the preamble.
All itemized lists now format correctly with proper spacing and margins.

PROBLEM:
- nbdev requires #| export directive on EACH cell to export when using # %% markers
- Cell markers inside class definitions split classes across multiple cells
- Only partial classes were being exported to tinytorch package
- Missing matmul, arithmetic operations, and activation classes in exports
SOLUTION:
1. Removed # %% cell markers INSIDE class definitions (kept classes as single units)
2. Added #| export to imports cell at top of each module
3. Added #| export before each exportable class definition in all 20 modules
4. Added __call__ method to Sigmoid for functional usage
5. Fixed numpy import (moved to module level from __init__)
MODULES FIXED:
- 01_tensor: Tensor class with all operations (matmul, arithmetic, shape ops)
- 02_activations: Sigmoid, ReLU, Tanh, GELU, Softmax classes
- 03_layers: Linear, Dropout classes
- 04_losses: MSELoss, CrossEntropyLoss, BinaryCrossEntropyLoss classes
- 05_autograd: Function, AddBackward, MulBackward, MatmulBackward, SumBackward
- 06_optimizers: Optimizer, SGD, Adam, AdamW classes
- 07_training: CosineSchedule, Trainer classes
- 08_dataloader: Dataset, TensorDataset, DataLoader classes
- 09_spatial: Conv2d, MaxPool2d, AvgPool2d, SimpleCNN classes
- 10-20: All exportable classes in remaining modules
TESTING:
- Test functions use 'if __name__ == "__main__"' guards
- Tests run in notebooks but NOT on import
- Rosenblatt Perceptron milestone working perfectly
RESULT:
✅ All 20 modules export correctly
✅ Perceptron (1957) milestone functional

This enables reliable ML systems training while protecting students
from common mistakes that break the Variable/Tensor compatibility.
BREAKTHROUGH IMPLEMENTATION:
✅ Auto-generated warnings now added to ALL exported files automatically
✅ Clear source file paths shown in every tinytorch/ file header
✅ CLAUDE.md updated with crystal clear rules: tinytorch/ = edit modules/
✅ Export process now runs warnings BEFORE success message
SYSTEMATIC PREVENTION:
- Every exported file shows: AUTOGENERATED! DO NOT EDIT! File to edit: [source]
- THIS FILE IS AUTO-GENERATED FROM SOURCE MODULES - CHANGES WILL BE LOST!
- To modify this code, edit the source file listed above and run: tito module complete
WORKFLOW ENFORCEMENT:
- Golden rule established: If file path contains tinytorch/, DON'T EDIT IT DIRECTLY
- Automatic detection of 16 module mappings from tinytorch/ back to modules/source/
- Post-export processing ensures no exported file lacks protection warning
VALIDATION:
✅ Tested with multiple module exports - warnings added correctly
✅ All tinytorch/core/ files now protected with clear instructions
✅ Source file paths correctly mapped and displayed
This prevents ALL future source/compiled mismatch issues systematically.
