Phase 03 Plan 04: Reward Screen & Game Loop Summary

Reward screen with pre-generated forest element images, companion comments, and complete game loop wiring (forest -> lesson -> reward -> forest)

Performance

• Duration: 3 min
• Started: 2026-03-29T11:50:31Z
• Completed: 2026-03-29T11:53:36Z
• Tasks: 2
• Files modified: 4

Accomplishments

• Complete game loop: lesson completion shows reward screen with generated/fallback image and companion comment
• Image pre-generation starts at lesson begin, placeholder with animated leaves shown while loading
• Review mode triggers every 3rd session, encouragement after 2x same level
• Exercise stats (correct, errors, errorKeys) accumulated in Progress across sessions

Task Commits

Each task was committed atomically:

1. Task 1: Reward module with pre-generation and reward screen - e599050 (feat)
2. Task 2: Wire complete flow in app.ts with review/repeat triggers - aaf9872 (feat)

Files Created/Modified

• src/forest/reward.ts - Reward module: startPreGeneration(), initRewardScreen(), fallback image handling
• src/app.ts - Updated game flow: lesson -> reward -> forest, review triggers, stats accumulation, progress migration
• index.html - Reward screen HTML with image area, companion comment, action buttons
• src/styles/main.css - Reward screen CSS with placeholder animation, image appear animation, button styles

Decisions Made

• Pre-generation uses fire-and-forget pattern at lesson start, awaited on reward screen with placeholder
• Fallback images loaded from existing static SVGs when rate-limited or API unavailable
• Progress migration function (migrateProgress) ensures backward compatibility with older IndexedDB data
• Grid position for new elements uses modulo 12 with random offset for natural placement

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Known Stubs

None - all data paths are wired to real sources.

Next Phase Readiness

• Game loop complete: forest -> lesson (3 phases) -> reward -> forest
• Ready for Plan 05 (parent area already has Ctrl+Shift+E shortcut wired from prior plan)
