Phase 03 Plan 02: Lesson Flow Summary

3-phase lesson state machine (discover -> practice -> words) with companion letter intros, word display UI, review mode, and repetition encouragement

Performance

• Duration: 4 min
• Started: 2026-03-29T11:44:16Z
• Completed: 2026-03-29T11:49:05Z
• Tasks: 2
• Files modified: 6

Accomplishments

• Extended typing engine with word mode: createWordExerciseState() splits words into letters with boundary tracking
• Lesson screen flows through 3 phases: discover (companion intro + key pulse) -> practice (letter exercise) -> words (word display with active letter)
• Review mode skips discover, mixes content from recent 2-3 levels
• Encouragement messages shown before lessons when repetition detected
• Cumulative stats (correct, errors, errorKeys) tracked across all phases and passed to onComplete

Task Commits

Each task was committed atomically:

1. Task 1: Extend typing engine with word mode - 958f446 (test: RED), 2c0c2f2 (feat: GREEN)
2. Task 2: Lesson screen 3-phase state machine - 770f566 (feat)

Files Created/Modified

• src/types.ts - TypingExerciseState extended with mode, words, wordBoundaries fields
• src/game/typing.ts - createWordExerciseState(), getCurrentWordIndex() functions
• src/game/typing.test.ts - 12 new tests for word mode, backwards compatibility, word index helper
• src/ui/screens.ts - Full rewrite of initLessonScreen with 3-phase state machine, review/encouragement params
• src/styles/main.css - Phase indicator, word display, discover pulse CSS
• index.html - Phase indicator div added to lesson screen

Decisions Made

• Word mode uses intervalMs=0: no falling/timing pressure during word typing (words are typed at child's pace)
• Discover phase skips space key: not meaningful to "discover" the spacebar
• Review word selection pulls 2 words from each of last 2-3 levels, shuffles, takes 4

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Lesson flow complete, ready for reward system integration (03-03)
• onComplete now passes stats for parent area tracking (03-04)
• Phase indicator and word display UI ready for audio integration (03-05)
