Major changes:
- Renamed entire system from "milestone" to "checkpoint" for academic framing
- Checkpoints are now positioned as academic progress markers in learning journey
- Implemented enhanced Rich CLI timeline with progress bars and connecting lines
- Added overall progress tracking (16/16 modules = 100%)
Enhanced timeline visualization:
- Horizontal view shows progress bar with filled/unfilled segments
- Visual connecting lines between checkpoints showing completion status
- Color-coded progress: green (complete), yellow (in-progress), dim (future)
- Percentage indicators for each checkpoint and overall progress
CLI improvements:
- `tito checkpoint status` - Shows overall and per-checkpoint progress
- `tito checkpoint timeline --horizontal` - Rich visual progress line
- `tito checkpoint timeline` - Vertical tree view with module details
- Better progress indicators with filled bars and connecting lines
Documentation updates:
- Renamed milestone-system.md to checkpoint-system.md
- Updated all references from milestone to checkpoint terminology
- Emphasized academic checkpoint philosophy and progress markers
- Added descriptions of new Rich CLI visualizations
Benefits:
- More academic framing aligns with educational context
- Visual progress bars provide immediate feedback on learning journey
- Checkpoint terminology is more familiar to students
- Rich CLI visualizations make progress tracking engaging
Problem: Grid cards were showing raw HTML code instead of rendering properly
Root cause: README converter was adding new grid cards while preserving
original ones, creating duplicate/conflicting grid sections
Solution:
- Modified book/convert_readmes.py to remove existing grid cards from
source READMEs before adding new interactive elements
- Added regex patterns to clean up grid-related markup
- Regenerated all 14 book chapters with fixed converter
- Grid cards now render properly as interactive buttons
Result: All chapters now have clean, properly formatted grid cards
that render correctly in Jupyter Book
✅ Remove unnecessary nesting: book/tinytorch-course/ → book/
✅ Update all path references in scripts and workflows
✅ Cleaner development experience with shorter paths
✅ Book builds successfully with simplified structure
Changes:
- Move all book files up one directory level
- Update convert_modules.py paths
- Update GitHub Actions workflow paths
- Update book configuration paths
- Test confirms everything works correctly
