Phase 03 Plan 01: Data Layer Foundation Summary

Word lists for levels 1-6 with TDD validation, extended Progress with accuracy stats, rate limits 10/5 per day

Performance

• Duration: 3 min
• Started: 2026-03-29T11:39:57Z
• Completed: 2026-03-29T11:42:37Z
• Tasks: 2
• Files modified: 7

Accomplishments

• Word lists for levels 1-6 (8-10 words each), validated to only use learned letters per level
• getWordsForLevel() with without-replacement and with-replacement sampling
• Progress interface extended with totalCorrect, totalErrors, errorKeyCounts, lastPlayedLevels
• LessonPhase type exported for lesson flow phases
• Rate limits updated from 1/1 to 10 text / 5 image per day

Task Commits

Each task was committed atomically:

1. Task 1: Word lists per level with validation tests - 420c0e1 (test: RED), 5a6ba70 (feat: GREEN)
2. Task 2: Extend Progress type and update rate limits - d4207bf (feat)

Files Created/Modified

• src/game/words.ts - Static word lists per level, getWordsForLevel() function
• src/game/words.test.ts - 8 tests validating word lists against level keys
• src/types.ts - Extended Progress interface, new LessonPhase type
• src/api/gemini.ts - Rate limit constants TEXT_RATE_LIMIT=10, IMAGE_RATE_LIMIT=5
• src/ui/screens.ts - New Progress field defaults in welcome screen
• src/api/gemini.test.ts - Updated rate limit tests for new limits
• src/storage/db.test.ts - Updated Progress test fixture with new fields

Decisions Made

• Levels 1-2 use letter combination patterns since no real German words can be formed with only F/J/D/K
• Rate limits raised to 10 text / 5 image per day (was 1 each) for practical usage

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Fixed invalid letters in word lists

• Found during: Task 1 (TDD GREEN phase)
• Issue: Plan's suggested words contained letters not in level allKeys (e.g., "halb" has "b" not in level 5, "salad" has letters not in level 4)
• Fix: Replaced invalid words with valid alternatives using only level-appropriate letters
• Files modified: src/game/words.ts
• Verification: All 8 word validation tests pass
• Committed in: 5a6ba70 (Task 1 GREEN commit)

2. [Rule 1 - Bug] Updated existing tests for new rate limits and Progress shape

• Found during: Task 2 (verification step)
• Issue: Existing tests expected old rate limit of 1 and old Progress shape without new fields
• Fix: Updated gemini.test.ts to call incrementApiCall 10/5 times, added new fields to db.test.ts fixture
• Files modified: src/api/gemini.test.ts, src/storage/db.test.ts
• Verification: All 76 tests pass, tsc --noEmit clean
• Committed in: d4207bf (Task 2 commit)

---

Total deviations: 2 auto-fixed (2 bugs) Impact on plan: Both fixes necessary for correctness. No scope creep.

Issues Encountered

None beyond the auto-fixed deviations above.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Word lists ready for lesson flow (03-02)
• Progress stats fields ready for parent area (03-04)
• LessonPhase type ready for lesson screen phases (03-02)
• Rate limits configured for reward system API calls (03-03)
