Phase 05 Plan 01: Multi-Wald-System — Pagination Data Model and Rendering Summary

Paginated forest rendering with SLOTS_PER_PAGE=12, currentForestPage in Progress type, and navigation DOM (prev/next buttons + page indicator) hidden by default until multiple pages exist.

Performance

• Duration: 2 min
• Started: 2026-03-29T20:56:13Z
• Completed: 2026-03-29T20:58:30Z
• Tasks: 2
• Files modified: 7

Accomplishments

• Extended Progress interface with currentForestPage: number and migrateProgress entry for backward compatibility
• Modified renderForestScene to accept a page parameter and slice elements[start..end] based on page * SLOTS_PER_PAGE
• Added navigation DOM structure (forest-nav container, prev/next buttons with aria-labels in German, page indicator span) hidden by default
• Added CSS for .forest__nav, .forest__nav-btn with 44px minimum touch targets and pastel BEM styling

Each task was committed atomically:

1. Task 1: Extend Progress type and add paginated renderForestScene - 559d57a (feat)
2. Task 2: Add navigation DOM elements and CSS styling - 348a71a (feat)

Plan metadata: (docs commit follows)

Files Created/Modified

• src/types.ts - Added currentForestPage: number field to Progress interface
• src/forest/scene.ts - Added SLOTS_PER_PAGE = 12 export, changed renderForestScene signature to (db, page, newElementId?), added nav UI update block
• src/app.ts - Added if (progress.currentForestPage === undefined) progress.currentForestPage = 0 in migrateProgress; updated renderForestScene call with page param
• src/storage/db.test.ts - Added currentForestPage: 0 to test Progress literal (Rule 1 auto-fix)
• src/ui/screens.ts - Added currentForestPage: 0 to initial Progress creation (Rule 1 auto-fix)
• index.html - Added <div id="forest-nav"> with prev/next buttons and page text between forest scene and level map
• src/styles/main.css - Added forest navigation CSS block after @keyframes forest-element-appear

Decisions Made

• Navigation UI is managed entirely from within renderForestScene: after rendering elements, it reads elements.length to calculate totalPages and updates the nav DOM. This keeps nav state always in sync with rendered content.
• SLOTS_PER_PAGE exported as a named constant so Plan 02 can import it without magic numbers.
• Progress objects in db.test.ts and screens.ts were updated to satisfy TypeScript strict interface checks — these are correctness fixes, not scope creep.

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Added currentForestPage to Progress literals in db.test.ts and screens.ts

• Found during: Task 1 (TypeScript compile check)
• Issue: Two files had inline const progress: Progress = {...} literals that were missing the new required field, causing tsc --noEmit to fail with TS2741 errors
• Fix: Added currentForestPage: 0 to both Progress object literals
• Files modified: src/storage/db.test.ts, src/ui/screens.ts
• Verification: npx tsc --noEmit exits 0 after fix
• Committed in: 559d57a (Task 1 commit)

---

Total deviations: 1 auto-fixed (Rule 1 - TypeScript type correctness) Impact on plan: Required fix for TypeScript compilation. No scope creep.

Issues Encountered

None — plan executed cleanly after TypeScript type fix.

Next Phase Readiness

• Plan 02 can import SLOTS_PER_PAGE from src/forest/scene.ts and wire click handlers for forest-nav-prev / forest-nav-next
• Progress.currentForestPage is persisted via existing saveProgress flow, no db schema changes needed
• Navigation DOM is in place and hidden; Plan 02 activates it by updating currentForestPage and calling renderForestScene
