Phase 01 Plan 03: Keyboard & Levels Summary

QWERTZ keyboard renderer with finger-colored keys, pulse/press animations, and level definitions 1-6 per spec progression table

Performance

• Duration: 3 min
• Started: 2026-03-29T09:05:09Z
• Completed: 2026-03-29T09:07:56Z
• Tasks: 2
• Files modified: 4

Accomplishments

• Level definitions 1-6 with correct key progressions matching spec section 4.1 (F/J/Space through E/I)
• Finger-to-CSS-variable mapping for all QWERTZ keys per spec section 8.3
• Full QWERTZ keyboard renderer with DE and CH layout support
• Pulse animation on target key and press animation on keydown via CSS classes
• 14 passing tests covering all level data and helper functions

Task Commits

Each task was committed atomically:

1. Task 1: Level definitions with key sets and finger mappings (TDD)
   • RED: 3462a67 (test) - 14 failing tests for levels array and helpers
   • GREEN: afae18d (feat) - level definitions 1-6 with finger mappings
2. Task 2: QWERTZ keyboard renderer with finger colors and animations - 2f0784f (feat)

Files Created/Modified

• src/game/levels.ts - Level definitions 1-6, getLevelByNumber, getKeysUpToLevel exports
• src/game/levels.test.ts - 14 tests covering levels, key progressions, finger mappings, helpers
• src/game/keyboard.ts - renderKeyboard, highlightKey, pressKey, updateKeyboardForLevel exports
• src/styles/main.css - Keyboard CSS: layout, finger colors, pulse/press animations, inactive styling

Decisions Made

• Finger color map duplicated in keyboard.ts (includes number row keys) rather than importing from levels.ts, keeping modules independent
• Keyboard uses CSS variable references (e.g., var(--finger-l-index)) set via inline style, resolved against design system variables

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Fixed TypeScript strict null check errors

• Found during: Task 2 (tsc --noEmit verification)
• Issue: Unused keyboardContainer variable and possible undefined array access in keyboard.ts; array index access in test file
• Fix: Removed unused variable, added non-null assertion on array access
• Files modified: src/game/keyboard.ts, src/game/levels.test.ts
• Verification: npx tsc --noEmit exits 0
• Committed in: 2f0784f (Task 2 commit)

---

Total deviations: 1 auto-fixed (1 bug) Impact on plan: Minor TypeScript strictness fix. No scope creep.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Known Stubs

None - no stubs or placeholder data that affect plan goals.

Next Phase Readiness

• Keyboard component ready for integration in typing exercise (Plan 04)
• Level data available for forest overview level grid (Plan 05)
• Both DE and CH layouts defined, identical for levels 1-6
