Port sudoku generation algorithm and integrate with game flow:
Core Changes:
- src/useBoard/SudokuGenerator.ts: Ported from src_old/lib/Sudoku.ts
- Full puzzle generation algorithm (robatron/sudoku.js)
- Supports all difficulty levels (easy through inhuman)
- Returns 81-character string representation
- src/useBoard/useBoard.ts: Enhanced with puzzle state
- Added boardRef and initialBoardRef for state management
- Added generateBoard(difficulty) method
- Updated renderBoard() to display givens from board string
- Cells show digits for givens, empty for '.' characters
- src/useGame.ts: Integrated game flow
- Reads difficulty from GameOptions (defaults to 'easy')
- Generates puzzle on startGame (gameStatus → 'started')
- Re-renders board on status changes
- quitGame returns to empty grid
Game Flow:
- Waiting: Empty 9x9 grid
- Press Space → startGame() → puzzle generated (~62 givens on easy)
- Press Q → quitGame() → empty grid
Testing platformHook integration:
- startGame trigger working via useKeyBindings
- quitGame trigger working via useKeyBindings
- Board state properly cleared/populated on status changes
Phase 20 complete. Next: Phase 30 (useGameStatus hook).
- Archive previous implementation attempt (src -> src_failed)
- Create comprehensive IMPLEMENTATION_PLAN.md with phased approach
- Create IMPLEMENTATION.md to track implementation progress
- Update example app to match vim-maze patterns:
- Simplify UI to desktop-only (no mobile support)
- Add score metrics display (time, keystrokes, final score)
- Update instructions for sudoku-specific keys (hjkl, i for edit)
- Remove unnecessary mobile hooks
Phase 5 complete. Ready to begin Phase 10 (Setup & Core Types).
