ede52e612f 🧹 Clean up repository: remove generated reports, backup files, and outdated documentation
- Remove generated report files (*.html, *.json) that should be recreated
- Remove temporary Quarto cache files (.quarto/cites/)
- Remove backup files (settings.ini.backup) when originals exist
- Remove legacy configuration (.cursorrules moved to .cursor/rules/)

  - CNN → Activation → Flatten → Dense pipelines
  - Deep CNN architectures with multiple stages
  - Numerical stability testing, batch processing
  - Moved from inline test in cnn_dev.py (proper separation)

- Update cnn_dev.py: Remove inline integration test
  - Replaced cross-module integration test with comment
  - Maintains clean separation between unit and integration tests

- Clean up test structure: Remove unused e2e/__init__.py

Result: Complete integration test coverage for CNN interactions
96 passing integration tests using real TinyTorch components

e5258bf2a2 Add comprehensive integration tests for missing component interactions
Level 1 (Core Data Flow Integration):
- test_tensor_cnn.py: Tests Tensor ↔ CNN operations (Conv2D, flatten) with real tensors
- test_tensor_autograd.py: Tests Tensor ↔ Autograd (Variable wrapping, forward/backward passes)
- test_dataloader_tensor.py: Tests DataLoader ↔ Tensors (real data pipeline producing tensors)

QA-structured tests with realistic scenarios:
- Shape handling and data type preservation
- Error handling and edge cases
- Realistic ML pipeline integration
- Batch processing and memory efficiency
- Complex architectures and training scenarios

Total: 43 new focused integration tests (13 + 14 + 16)
Result: 77/79 integration tests passing (98% success rate)
Missing tests now covered: real component integration vs mock-based testing

91981069e0 Remove redundant test_setup.py
- Removed test_setup.py as it duplicated inline tests without integration value
- Setup module functions already comprehensively tested in setup_dev.py inline tests
- Maintains clean test architecture: inline (unit) → integration (cross-module) → e2e (workflows)
- Final count: 39 focused integration tests vs previous mix of unit/integration

d1f587c55d Reorganize tests: Remove mocks, add real integration tests
REMOVED (Mock-based tests that duplicate inline tests):
• test_activations.py - Used MockTensor instead of real Tensor
• test_layers.py - Used MockTensor instead of real Tensor
• test_networks.py - Used MockTensor/MockLayer instead of real components
• test_cnn.py - Used MockTensor instead of real Tensor
• test_dataloader.py - Used MockTensor/MockDataset instead of real components

ADDED (Real integration tests with actual TinyTorch components):
• integration/test_tensor_activations.py - Tests real Tensor ↔ Activations integration
• integration/test_layers_networks.py - Tests real Dense ↔ Sequential/MLP integration
• e2e/ directory structure for end-to-end tests

RESULT:
• Reduced test count from 209 → 70 (removed 139 redundant mock-based tests)
• All 70 remaining tests use real components for true integration testing
• Clear separation: inline tests (component validation) vs integration tests (cross-module)
• Better QA structure following proper testing pyramid

This follows QA best practices: since all modules are working and building on each
other, integration tests should use real components, not mocks. Mocks were preventing
us from catching actual integration issues.

a0ca20ab9f Clean up extreme and unreasonable tests in tests/ directory
Removed/simplified overly extreme tests that don't add educational value:

• test_setup.py:
  - Removed brittle performance tests with specific timing requirements
  - Removed complex memory usage profiling tests
  - Kept reasonable system accuracy tests

• test_layers.py:
  - Simplified large batch test (1000 → 32 batch size)
  - Reduced input/output dimensions to realistic educational sizes
  - Kept important behavior tests (weight immutability, etc.)

• test_dataloader.py:
  - Removed timing-based performance tests
  - Simplified scalability tests (1000 → 100 max dataset size)
  - Renamed tests for clarity (memory_efficiency → functionality)

• test_cnn.py:
  - Removed incomplete mathematical property tests
  - Eliminated conceptual tests that don't actually verify properties
  - Kept solid functional and integration tests

Results: 214 → 209 tests, all still passing (100% success rate)
Focus on reasonable scenarios that students will encounter in practice.

62d4820900 Add sync/export reminder to test command
- Add prominent yellow reminder box before all test executions
- Shows clear instructions for 'tito export' and 'tito nbdev build'
- Ensures users sync modules to package before testing
- Displays in both single module tests and all tests
- Prevents testing stale code by reminding users to export latest changes

This ensures users always test the most current code from their development modules.

ebabb84e2e Fix inline test failures across 3 modules
- 00_setup: Fix naming inconsistency (setup_health → setup_score)
  - Tests expected 'setup_score' key but implementation returned 'setup_health'
  - Updated all references to use consistent 'setup_score' naming
  - Result: 37/37 tests now passing

- 05_cnn: Fix flatten function shape expectations
  - Comprehensive tests expected (4,) shape but integration tests expected (1,4) shape
  - Made comprehensive tests consistent with integration test expectations
  - Flatten function now correctly preserves batch dimension for realistic usage
  - Result: 39/39 tests now passing

- 08_optimizers: Fix recursion error in test execution
  - Direct test call was causing infinite recursion loop
  - Removed problematic direct test call, rely on auto-discovery system
  - Result: 5/5 tests now passing

All inline tests now pass: 214/214 tests (100% success rate)
