Major restructure: Remove Confluence, add V2 data structure, organize for dev/prod

- Import real data from PDF (35 Bambu Lab filaments)
- Remove all Confluence integration and dependencies
- Implement new V2 data structure with proper inventory tracking
- Add backwards compatibility for existing data
- Create enhanced UI components (ColorSwatch, InventoryBadge, MaterialBadge)
- Add advanced filtering with quick filters and multi-criteria search
- Organize codebase for dev/prod environments
- Update Lambda functions to support both V1/V2 formats
- Add inventory summary dashboard
- Clean up project structure and documentation

+## Environment Files
+
+- `.env.development` - Development environment variables
+- `.env.production` - Production environment variables
+- `.env.local` - Local overrides (not committed)
+- `.env.development.local` - Local dev overrides (not committed)
+
+## Key Concepts
+
+### Environments
+- **Development**: Uses `dev` API Gateway stage and separate DynamoDB table
+- **Production**: Uses `production` API Gateway stage and main DynamoDB table
+
+### Data Flow
+1. Frontend (Next.js) → API Gateway → Lambda Functions → DynamoDB
+2. Authentication via JWT tokens stored in localStorage
+3. Real-time data updates every 5 minutes
+
+### Infrastructure
+- Managed via Terraform
+- Separate resources for dev/prod
+- AWS services: DynamoDB, Lambda, API Gateway, Amplify
+
+## Development Workflow
+
+1. **Local Development**
+   ```bash
+   npm run dev
+   ```
+
+2. **Deploy to Dev**
+   ```bash
+   cd terraform
+   terraform apply -var-file=environments/dev/terraform.tfvars
+   ```
+
+3. **Deploy to Production**
+   ```bash
+   cd terraform
+   terraform apply -var-file=environments/prod/terraform.tfvars
+   ```
+
+## Data Management
+
+### Import Data from PDF
+```bash
+node scripts/data-import/import-pdf-data.js
+```
+
+### Clear DynamoDB Table
+```bash
+node scripts/data-import/clear-dynamo.js
+```
+
+## Security
+
+- No hardcoded credentials
+- JWT authentication for admin
+- Environment-specific configurations
+- Pre-commit security checks

+# Improved Data Structure Proposal
+
+## Current Issues
+1. Mixed languages (English/Serbian)
+2. String fields for numeric/boolean values
+3. Inconsistent status representation
+4. No proper inventory tracking
+5. Missing important metadata
+
+## Proposed Structure
+
+```typescript
+interface Filament {
+  // Identifiers
+  id: string;
+  sku?: string;  // For internal tracking
+  
+  // Product Info
+  brand: string;
+  type: 'PLA' | 'PETG' | 'ABS' | 'TPU' | 'SILK' | 'CF' | 'WOOD';
+  material: {
+    base: 'PLA' | 'PETG' | 'ABS' | 'TPU';
+    modifier?: 'Silk' | 'Matte' | 'Glow' | 'Wood' | 'CF';
+  };
+  color: {
+    name: string;
+    hex?: string;      // Color code for UI display
+    pantone?: string;  // For color matching
+  };
+  
+  // Physical Properties
+  weight: {
+    value: number;     // 1000 for 1kg, 500 for 0.5kg
+    unit: 'g' | 'kg';
+  };
+  diameter: number;    // 1.75 or 2.85
+  
+  // Inventory Status
+  inventory: {
+    total: number;     // Total spools
+    available: number; // Available for use
+    inUse: number;     // Currently being used
+    locations: {
+      vacuum: number;  // In vacuum storage
+      opened: number;  // Opened but usable
+      printer: number; // Loaded in printer
+    };
+  };
+  
+  // Purchase Info
+  pricing: {
+    purchasePrice?: number;
+    currency: 'RSD' | 'EUR' | 'USD';
+    supplier?: string;
+    purchaseDate?: string;
+  };
+  
+  // Condition

+    isRefill: boolean;
+    openedDate?: string;
+    expiryDate?: string;
+    storageCondition: 'vacuum' | 'sealed' | 'opened' | 'desiccant';
+    humidity?: number;  // Last measured
+  };
+  
+  // Metadata
+  tags: string[];      // ['premium', 'engineering', 'easy-print']
+  notes?: string;      // Special handling instructions
+  images?: string[];   // S3 URLs for photos
+  
+  // Timestamps
+  createdAt: string;
+  updatedAt: string;
+  lastUsed?: string;
+}
+```
+
+## Benefits
+
+### 1. **Better Filtering**
+```typescript
+// Find all sealed PLA under 1kg
+filaments.filter(f => 
+  f.material.base === 'PLA' && 
+  f.weight.value <= 1000 && 
+  f.condition.storageCondition === 'vacuum'
+)
+```
+
+### 2. **Inventory Management**
+```typescript
+// Get total available filament weight
+const totalWeight = filaments.reduce((sum, f) => 
+  sum + (f.inventory.available * f.weight.value), 0
+);
+
+// Find low stock items
+const lowStock = filaments.filter(f => 
+  f.inventory.available <= 1 && f.inventory.total > 0
+);
+```
+
+### 3. **Color Management**
+```typescript
+// Group by color for visualization
+const colorGroups = filaments.reduce((groups, f) => {
+  const color = f.color.name;
+  groups[color] = groups[color] || [];
+  groups[color].push(f);
+  return groups;
+}, {});
+```
+
+### 4. **Usage Tracking**
+```typescript
+// Find most used filaments
+const mostUsed = filaments
+  .filter(f => f.lastUsed)
+  .sort((a, b) => new Date(b.lastUsed) - new Date(a.lastUsed))
+  .slice(0, 10);
+```
+
+## Migration Strategy
+
+### Phase 1: Add New Fields (Non-breaking)
+```javascript
+// Update Lambda to handle both old and new structure
+const migrateFilament = (old) => ({
+  ...old,
+  material: {
+    base: old.tip || 'PLA',
+    modifier: old.finish !== 'Basic' ? old.finish : undefined
+  },
+  color: {
+    name: old.boja
+  },
+  weight: {
+    value: 1000, // Default 1kg
+    unit: 'g'
+  },
+  inventory: {
+    total: parseInt(old.kolicina) || 1,
+    available: old.otvoreno ? 0 : 1,
+    inUse: 0,
+    locations: {
+      vacuum: old.vakum ? 1 : 0,
+      opened: old.otvoreno ? 1 : 0,
+      printer: 0
+    }
+  },
+  condition: {
+    isRefill: old.refill === 'Da',
+    storageCondition: old.vakum ? 'vacuum' : (old.otvoreno ? 'opened' : 'sealed')
+  }
+});
+```
+
+### Phase 2: Update UI Components
+- Create new filter components for material type
+- Add inventory status indicators
+- Color preview badges
+- Storage condition icons
+
+### Phase 3: Enhanced Features
+1. **Barcode/QR Integration**: Generate QR codes for each spool
+2. **Usage History**: Track which prints used which filament
+3. **Alerts**: Low stock, expiry warnings
+4. **Analytics**: Cost per print, filament usage trends
+
+## DynamoDB Optimization
+
+### Current Indexes
+- brand-index
+- tip-index  
+- status-index
+
+### Proposed Indexes
+```terraform
+global_secondary_index {
+  name = "material-color-index"
+  hash_key = "material.base"
+  range_key = "color.name"
+}
+
+global_secondary_index {
+  name = "inventory-status-index"
+  hash_key = "condition.storageCondition"
+  range_key = "inventory.available"
+}
+
+global_secondary_index {
+  name = "brand-type-index"
+  hash_key = "brand"
+  range_key = "material.base"
+}
+```
+
+## Example Queries
+
+### Find all available green filaments
+```javascript
+const greenFilaments = await dynamodb.query({
+  IndexName: 'material-color-index',
+  FilterExpression: 'contains(color.name, :green) AND inventory.available > :zero',
+  ExpressionAttributeValues: {
+    ':green': 'Green',
+    ':zero': 0
+  }
+}).promise();
+```
+
+### Get inventory summary
+```javascript
+const summary = await dynamodb.scan({
+  TableName: TABLE_NAME,
+  ProjectionExpression: 'brand, material.base, inventory'
+}).promise();
+
+const report = summary.Items.reduce((acc, item) => {
+  const key = `${item.brand}-${item.material.base}`;
+  acc[key] = (acc[key] || 0) + item.inventory.total;
+  return acc;
+}, {});
+```
+
+## UI Improvements
+
+### 1. **Visual Inventory Status**
+```tsx
+<div className="flex gap-2">
+  {filament.inventory.locations.vacuum > 0 && (
+    <Badge icon="vacuum" count={filament.inventory.locations.vacuum} />
+  )}
+  {filament.inventory.locations.opened > 0 && (
+    <Badge icon="box-open" count={filament.inventory.locations.opened} />
+  )}
+</div>
+```
+
+### 2. **Color Swatches**
+```tsx
+<div 
+  className="w-8 h-8 rounded-full border-2"
+  style={{ backgroundColor: filament.color.hex || getColorFromName(filament.color.name) }}
+  title={filament.color.name}
+/>
+```
+
+### 3. **Smart Filters**
+- Quick filters: "Ready to use", "Low stock", "Refills only"
+- Material groups: "Standard PLA", "Engineering", "Specialty"
+- Storage status: "Vacuum sealed", "Open spools", "In printer"
+
+Would you like me to implement this improved structure?

-
-```bash
-npm run migrate:clear
-```
-
-### Manual execution
-
-```bash
-# Migrate without clearing
-node migrate-with-parser.js
-
-# Clear existing data first
-node migrate-with-parser.js --clear
-```
-
-## What the script does
-
-1. **Checks for Confluence credentials**
-   - If found: Fetches data from Confluence page
-   - If not found: Uses local `public/data.json` file
-
-2. **Parses the data**
-   - Extracts filament information from HTML table (Confluence)
-   - Or reads JSON directly (local file)
-
-3. **Prepares data for DynamoDB**
-   - Generates unique IDs for each filament
-   - Adds timestamps (createdAt, updatedAt)
-
-4. **Writes to DynamoDB**
-   - Writes in batches of 25 items (DynamoDB limit)
-   - Shows progress during migration
-
-5. **Verifies the migration**
-   - Counts total items in DynamoDB
-   - Shows a sample item for verification
-
-## Troubleshooting
-
-- **Table not found**: Make sure you've run `terraform apply` first
-- **Access denied**: Check your AWS credentials and permissions
-- **Confluence errors**: Verify your API token and page ID
-- **Empty migration**: Check that the Confluence page has a table with the expected format
