- Integration tests: 21/22 passing (95.5% success rate)
- Module tests: All individual modules passing
- General functionality: 4/5 tests passing with core training working
Technical Details:
- Fixed gradient data access patterns throughout activations.py

IMPORT PATH FIXES: All modules now reference correct directories
Fixed Paths:
✅ 02_tensor → 01_tensor (in all modules)
✅ 03_activations → 02_activations (in all modules)
✅ 04_layers → 03_layers (in all modules)
✅ 05_losses → 04_losses (in all modules)
✅ Added comprehensive fallback imports for 07_training
Module Test Status:
✅ 01_tensor, 02_activations, 03_layers: All tests pass
✅ 06_optimizers, 08_spatial: All tests pass
🔧 04_losses: Syntax error (markdown in Python)
🔧 05_autograd: Test assertion failure
🔧 07_training: Import paths fixed, ready for retest
All import dependencies now correctly reference reorganized module structure.
CLEANUP: Removed duplicate/obsolete configuration files
Removed Files:
- All old numbered .yml files (02_tensor.yml, 03_activations.yml, etc.)
- These were leftover from the module reorganization
- Had incorrect dependencies (still referenced 'setup')
Current State:
✅ CLI correctly uses module.yaml files (19 modules)
✅ All module.yaml files have correct dependencies
✅ No more duplicate/conflicting configuration files
✅ Clean module structure with single source of truth
The CLI was already using module.yaml correctly, so this cleanup removes
the confusing duplicate files without affecting functionality.
PERFECT WORKFLOW: Clean lifecycle commands with distinct purposes
New Commands (No Overlaps):
✅ tito module start 01 → Start working on module (first time only)
✅ tito module resume 01 → Resume working on module (continue work)
✅ tito module complete 01 → Complete module (test + export)
✅ tito module status → Show progress with 3 states
Smart Features:
✅ State tracking: ⏳ not started → 🚀 in progress → ✅ completed
✅ Smart validation: start checks if already started, suggests resume
✅ Smart defaults: resume/complete work without module number
✅ Progress persistence: JSON file tracks started/completed modules
✅ Clear guidance: Always shows next logical step
User Journey:
1. tito setup → Environment setup
2. tito module start 01 → Begin tensors (marks as started)
3. Work in Jupyter, save → Natural development
4. tito module complete 01 → Test, export, mark completed
5. tito module start 02 → Begin activations
6. tito module resume 02 → Continue activations later
No command overlaps - each has distinct purpose and clear mental model!
