QUICK START - Data Persistence Architecture (2025-12-23)

STATUS: ✅ Phase 1 Complete
LOCATION: /home/wekan/repos/wekan/docs/Security/PerUserDataAudit2025-12-23/

🎯 The Change in 1 Sentence

Swimlane height and list width are now per-board (shared), not per-user (private).

📝 What Changed

Swimlanes (swimlanes.js)

✅ ADDED: height: { type: Number, default: -1, range: -1 or 50-2000 }
📍 Line: ~108-130

Lists (lists.js)

✅ ADDED: width: { type: Number, default: 272, range: 100-1000 }
📍 Line: ~162-182

Cards, Checklists, ChecklistItems

✅ NO CHANGE - Positions already per-board in sort field

📊 Per-Board vs Per-User Quick Reference

✅ PER-BOARD (All Users See Same)

• Swimlane height
• List width
• Card/checklist/checklistItem positions
• All titles, colors, descriptions

🔒 PER-USER (Only You See Yours)

• Collapsed swimlanes (yes/no)
• Collapsed lists (yes/no)
• Hidden label text (yes/no)

📁 Documentation Quick Links

✅ What's Complete (Phase 1)

• Schema: Added height to swimlanes
• Schema: Added width to lists
• Validation: Both fields validate ranges
• Documentation: 12 comprehensive guides
• Backward compatible: Both fields optional

⏳ What's Left (Phases 2-4)

• Phase 2: Refactor user model (~2-4h)
• Phase 3: Migrate data (~1-2h)
• Phase 4: Update UI (~4-6h)

See IMPLEMENTATION_GUIDE.md for details

🧪 Quick Test

// Test swimlane height validation
Swimlanes.insert({ boardId: 'b1', height: -1 })       // ✅ OK (auto)
Swimlanes.insert({ boardId: 'b1', height: 100 })      // ✅ OK (valid)
Swimlanes.insert({ boardId: 'b1', height: 25 })       // ❌ FAILS (too small)
Swimlanes.insert({ boardId: 'b1', height: 3000 })     // ❌ FAILS (too large)

// Test list width validation
Lists.insert({ boardId: 'b1', width: 272 })           // ✅ OK (default)
Lists.insert({ boardId: 'b1', width: 500 })           // ✅ OK (valid)
Lists.insert({ boardId: 'b1', width: 50 })            // ❌ FAILS (too small)
Lists.insert({ boardId: 'b1', width: 2000 })          // ❌ FAILS (too large)
