**Date:** 2026-03-29
**Phase:** 05-multi-wald-system-wald-pagination-und-navigation-zwischen-w-ldern
**Mode:** assumptions
**Areas analyzed:** Pagination Data Model, Navigation UI, Aktueller Wald in Progress, Rendering-Ansatz

## Assumptions Presented

### Pagination Data Model
| Assumption | Confidence | Evidence |
|------------|-----------|----------|
| Wald-Seite aus Element-Index berechnen, kein DB-Schema-Change | Likely | src/forest/reward.ts slotIndex, src/types.ts ForestElement, src/storage/db.ts DB_VERSION=1 |

### Navigation UI
| Assumption | Confidence | Evidence |
|------------|-----------|----------|
| Links/Rechts-Pfeiltasten + "Wald X von Y" Anzeige | Likely | Zielgruppe 7 Jahre, bestehende Button-Patterns, Forest-Grid absolut positioniert |

### Aktueller Wald in Progress
| Assumption | Confidence | Evidence |
|------------|-----------|----------|
| currentForestPage im Progress-Singleton persistieren | Confident | Progress ist Singleton, wird bei jedem Forest-Init gelesen |

### Rendering-Ansatz
| Assumption | Confidence | Evidence |
|------------|-----------|----------|
| renderForestScene mit Page-Parameter, Slice statt Pre-Rendering | Confident | Bestehendes tear-down-rebuild Pattern, activeObjectUrls Management |
