**Date:** 2026-03-29
**Phase:** 03-Komplettes Spielerlebnis
**Mode:** assumptions
**Areas analyzed:** Lesson Flow Architecture, Forest Scene, Reward Flow, Parent Area, Rate Limiting

## Assumptions Presented

### Lesson Flow Architecture
| Assumption | Confidence | Evidence |
|------------|-----------|----------|
| Sub-phases as internal state machine in lesson screen | Confident | ScreenName has 5 entries (D-01 from Phase 1) |
| Word building extends existing typing engine with mode param | Likely | typing.ts letters array + currentLetterIndex reusable |

### Forest Scene
| Assumption | Confidence | Evidence |
|------------|-----------|----------|
| SVG background + HTML overlay CSS grid for forest elements | Likely | ForestElement.position exists, fallback SVGs ready |

### Reward Flow
| Assumption | Confidence | Evidence |
|------------|-----------|----------|
| Pre-generation at lesson start, await on reward screen | Likely | generateImage async, screen-reward exists but empty |

### Parent Area
| Assumption | Confidence | Evidence |
|------------|-----------|----------|
| Extend Progress interface with stats, no DB version bump | Confident | IndexedDB schema-less for values |

## Corrections Made

No corrections — all assumptions confirmed.

## External Research Flagged

- Rate limit adequacy: current 1/1 per day needs increase to ~10 text + 5 image per day
