+## 🗓️ 15. December 2024 - Session 4: Micro Farm & Minting System
+
+**Trajanje:** 4.5 uri (00:50 - 01:42)  
+**Cilj:** Phase 37 (Micro Farm) + Phase 40 (Minting) Implementation
+
+### ✅ Dosežki:
+
+**PHASE 37: MICRO FARM & EXPANSION** 🌱
+1. **8x8 Micro Farm System:**
+   - ✅ Initial farm boundary (center of 100x100 map)
+   - ✅ White boundary visualization with corner markers
+   - ✅ Tile tracking system (Set-based unlocked tiles)
+   - ✅ MicroFarmSystem.js created
+
+2. **Visual Feedback:**
+   - ✅ Locked tile overlay (30% opacity black)
+   - ✅ Clear farm vs locked distinction
+   - ✅ Dynamic rendering (15 tile viewRange)
+   - ✅ Depth-sorted overlays
+
+3. **Farming Restrictions:**
+   - ✅ Block tilling outside farm boundary
+   - ✅ Error messages with floating text
+   - ✅ FarmingSystem integration
+   - ✅ Boundary validation on every action
+
+4. **Expansion System:**
+   - ✅ 4-direction unlock buttons (⬆️⬇️➡️⬅️)
+   - ✅ Cost system (50 gold per 2x2 expansion)
+   - ✅ Interactive UI with hover effects
+   - ✅ Dynamic boundary updates
+
+5. **Minimap Integration:**
+   - ✅ Farm boundary visible in minimap
+   - ✅ White box indicator
+   - ✅ Fixed terrainSystem compatibility
+   - ✅ Player-relative rendering
+
+**PHASE 40: MINTING SYSTEM** 💰
+1. **Core System:**
+   - ✅ Smelter (Gold Ore → Gold Bar)
+   - ✅ Mint (Gold Bar → Gold Coins)
+   - ✅ MintingSystem.js created
+   - ✅ Processing time tracking
+
+2. **Recipes:**
+   - ✅ Smelt: 1 ore + 1 coal → 1 bar (5s)
+   - ✅ Mint: 1 bar → 10 coins (3s)
+   - ✅ Fuel system for smelter
+   - ✅ Progress tracking
+
+3. **Visual Representation:**
+   - ✅ Smelter sprite (🔥 brown with fire outline)
+   - ✅ Mint sprite (💰 gold with coin icon)
+   - ✅ Processing feedback
+   - ✅ Completion floating text
+
+### 🔧 Technical Fixes:
+
+1. **Flat2DTerrainSystem:**
+   - ✅ Added decorationsMap (Map) for InteractionSystem
+   - ✅ Fixed crash in handleInteraction
+   - ✅ Compatibility with existing systems
+
+2. **UIScene Minimap:**
+   - ✅ Fixed player position reading (gridX/gridY)
+   - ✅ TerrainSystem.getTile() integration
+   - ✅ Farm boundary rendering
+   - ✅ Circular minimap compatibility
+
+3. **Variable Scope:**
+   - ✅ Fixed farmCenterX/Y references
+   - ✅ Proper this. prefixing
+   - ✅ Overlay rendering fixes
+
+### ❌ Izzivi:
+
+1. **AI Image Generation:**
+   - Green screen transparency NE deluje zanesljivo
+   - Manual background removal potreben
+   - **LEKCIJA:** Direct transparent PNG je edina pot!
+
+2. **Sprite Processing:**
+   - Automatic green removal briše pravilne barve (pink, red)
+   - Disabled processAllTransparency() globally
+   - **LEKCIJA:** Ready assets = no processing!
+
+3. **Complexity:**
+   - 3 velike features v 1 session
+   - Water auto-tiling postponed
+   - Phase 38 postponed
+
+### 🎯 Naslednji Koraki:
+
+1. **Phase 38: Town Repair** (Next priority)
+   - Ruined buildings system
+   - NPC relationship (hearts)
+   - Trading shops
+   - Repair mechanics
+
+2. **Water Auto-Tiling** (Visual improvement)
+   - Edge detection
+   - Smooth transitions
+   - Wave animations
+
+3. **Weather Improvements:**
+   - Rain ripples on water
+   - Better puddles
+   - Particle effects
+
+### 📊 Statistika:
+
+- **Session trajanje:** 4.5 uri
+- **Datoteke spremenjene:** 6
+- **Nove datoteke:** 2 (MicroFarmSystem.js, MintingSystem.js)
+- **Linije kode:** +500
+- **Features completed:** 2 major phases
+- **Commits:** 2 (Phase 37, Phase 40)
+
+### 💡 Lekcije:
+
+1. **Micro systems work!** - 8x8 start je dovolj za gameplay
+2. **Visual feedback je critical** - overlay + boundaries = clarity
+3. **Expansion mechanics engaging** - unlock buttons + cost = satisfying
+4. **Minting = unique economy** - no random coin drops!
+5. **4.5h session možen** - ampak potreben break! 😴
