+# Phase 2 Plan 1: Legacy Data Extraction Summary
+
+**Furniture inventory extracted from legacy PHP: 118 items across 7 rooms + 32 additional work fields**
+
+## Accomplishments
+
+- Created Umzugsliste_Furniture_Data class with singleton pattern
+- Extracted all 118 furniture items from legacy liste.php with exact cbm values
+- Extracted 6 additional work sections (Montage, Schrank, Elektriker, Dübelarbeiten, Packarbeiten, Anfahrt) with 32 fields total
+- Preserved exact item names, cbm values, and room structure from legacy
+- All data structured as static arrays for immediate use in form rendering
+
+## Files Created/Modified
+
+- `includes/class-furniture-data.php` - Furniture data structure class with complete legacy data
+
+## Decisions Made
+
+- **Static arrays vs database**: Used static arrays (not database) to match legacy approach. Admin editing is a future feature, not in current roadmap.
+- **Room key naming**: Established lowercase underscore convention (e.g., `kueche_esszimmer`, `wohnzimmer`)
+- **Küche/Esszimmer merge**: Combined separate legacy "Küche" and "Esszimmer" form arrays into single `kueche_esszimmer` key (18 items total)
+- **Field type annotations**: Added `type` property to additional work fields to indicate rendering requirements:
+  - `checkbox` - Simple checkbox
+  - `abbau_aufbau` - Two checkboxes (Abbau/Aufbau)
+  - `checkbox_anzahl` - Checkbox + anzahl (quantity) text field
+  - `text` - Text input field
+
+## Data Breakdown
+
+**Rooms (118 items):**
+- Wohnzimmer: 32 items
+- Schlafzimmer: 15 items
+- Arbeitszimmer: 11 items
+- Bad: 3 items
+- Küche/Esszimmer: 18 items
+- Kinderzimmer: 18 items
+- Keller/Speicher/Garage: 21 items
+
+**Additional Work Sections (32 fields):**
+- Montagearbeiten: 2 fields
+- Schrank: 6 fields
+- Elektriker/Installateur: 5 fields
+- Dübelarbeiten: 5 fields
+- Packarbeiten: 6 fields
+- Anfahrt: 8 fields
+
+## Issues Encountered
+
+None. Legacy data extraction was straightforward. The only discovery was that "Esszimmer" (not "Küche") is used as the form field name prefix in legacy, requiring script adjustment during extraction.
+
+## Commits
+
+- `5bb324c` - feat(02-01): extract furniture data from legacy into structured class
+- `4d2a584` - feat(02-01): extract additional work sections from legacy
+
+## Next Phase Readiness
+
+Data extraction complete. Phase 2 objectives achieved.
+
+**Ready for Phase 3** (Settings System) or **Phase 4** (Form Rendering).
+
+Phase 4 will consume `get_rooms()`, `get_furniture_items($room)`, and `get_additional_work()` to render the complete 7-room form structure with all furniture items and additional work sections.
