+# Report Builder Enhancements
+
+## Overview
+
+This document describes the enhancements made to the Report Builder functionality in InvoicePlane v2. The changes address several issues and add new capabilities for managing report templates and blocks.
+
+## Problems Solved
+
+### 1. Block Width Options
+**Problem**: Report blocks only supported half-width and full-width options.
+
+**Solution**: Extended `ReportBlockWidth` enum to support four width options:
+- `ONE_THIRD` (4 columns in 12-column grid)
+- `HALF` (6 columns)
+- `TWO_THIRDS` (8 columns)
+- `FULL` (12 columns)
+
+### 2. Block Edit Form Not Populating
+**Problem**: When clicking "Edit" on a block in the Report Builder, the form opened but didn't show the record's data.
+
+**Solution**: 
+- Fixed `configureBlockAction()` in `ReportBuilder.php` to properly lookup blocks using `block_type`
+- Added proper form population in both `fillForm()` and `mountUsing()` methods
+- Added logging (`Log::info`) for debugging purposes to help identify data issues
+
+### 3. Debugging Visibility
+**Problem**: Using `dd()` in Livewire/Alpine context didn't show debug output.
+
+**Solution**: Replaced debug dumps with `Log::info()` calls that write to Laravel's log files:
+```php
+Log::info('Block data for edit:', $data);
+Log::info('Mounting block config with data:', $data);
+```
+
+### 4. Field Drag/Drop Canvas
+**Problem**: No way to configure which fields appear in a block or their layout.
+
+**Solution**: 
+- Created a drag-and-drop field canvas interface
+- Added `fields-canvas.blade.php` view component
+- Integrated canvas into the block editor slideover panel
+- Fields can be dragged from "Available Fields" to the canvas
+- Field configurations are saved to JSON files
+
+### 5. Block Width Rendering
+**Problem**: Blocks in the init() function didn't respect their configured widths (e.g., full-width invoice_items showed as half-width).
+
+**Solution**: Updated the Alpine.js template in `design-report-template.blade.php` to properly calculate grid-column spans based on block widths:
+```javascript
+grid-column: span ${block.position.width >= 12 ? '2' : (block.position.width >= 8 ? '2' : '1')}
+```
+
+## Technical Implementation
+
+### Enum Enhancement
+```php
+enum ReportBlockWidth: string
+{
+    case ONE_THIRD = 'one_third';
+    case HALF = 'half';
+    case TWO_THIRDS = 'two_thirds';
+    case FULL = 'full';
+
+    public function getGridWidth(): int
+    {
+        return match ($this) {
+            self::ONE_THIRD => 4,
+            self::HALF => 6,
+            self::TWO_THIRDS => 8,
+            self::FULL => 12,
+        };
+    }
+}
+```
+
+### Field Storage Architecture
+Fields are stored separately from blocks:
+- **Block Records**: Stored in `report_blocks` database table with metadata
+- **Field Configurations**: Stored in JSON files at `storage/app/report_blocks/{slug}.json`
+
+This separation allows:
+- Fast block queries without loading heavy field data
+- Easy version control and backup of field configurations
+- Flexibility to extend field properties without schema changes
+
+### ReportBlockService Methods
+```php
+// Save fields to JSON file
+saveBlockFields(ReportBlock $block, array $fields): void
+
+// Load fields from JSON file
+loadBlockFields(ReportBlock $block): array
+
+// Get complete configuration including fields
+getBlockConfiguration(ReportBlock $block): array
+```
+
+### Field Canvas Component
+The drag/drop canvas supports:
+- Dragging available fields to canvas
+- Removing fields from canvas
+- Preserving field positions and dimensions
+- Complex field metadata (styles, visibility, etc.)
+- Real-time sync with Livewire component state
+
+## Database Changes
+
+### Migration: report_blocks table
+Updated default values and column comments:
+```php
+// Updated width column to support 4 options
+$table->string('width')->default('half'); // one_third, half, two_thirds, or full
+
+// Added data_source default
+$table->string('data_source')->default('invoice');
+```
+
+**Note on Configuration Storage:**
+Block field configurations are **not** stored in the database. Instead, they are stored as JSON files in the filesystem at `storage/app/report_blocks/{slug}.json`. This separates the block metadata (in database) from the field layout configuration (in files), allowing for easier version control and more flexible configuration management.
+
+## Testing
+
+All new functionality is covered by comprehensive PHPUnit tests (marked as incomplete per requirements):
+
+### Unit Tests
+- `ReportBlockWidthTest`: Tests enum values and grid width calculations (6 tests)
+- `ReportBlockServiceFieldsTest`: Tests JSON field storage/loading (9 tests)
+
+### Feature Tests
+- `ReportBuilderBlockWidthTest`: Tests width rendering in designer (8 tests)
+- `ReportBuilderBlockEditTest`: Tests form data population (8 tests)
+- `ReportBuilderFieldCanvasIntegrationTest`: Tests field canvas workflow (8 tests)
+
+**Total: 39 test cases**
+
+To run the tests:
+```bash
+php artisan test --filter=ReportBlock
+php artisan test --filter=ReportBuilder
+```
+
+## Usage Examples
+
+### Creating a Block with Custom Width
+```php
+$block = ReportBlock::create([
+    'block_type' => 'custom_block',
+    'name' => 'Custom Block',
+    'width' => ReportBlockWidth::TWO_THIRDS,
+    'data_source' => 'invoice',
+    'default_band' => 'header',
+]);
+```
+
+### Saving Field Configuration
+```php
+$service = app(ReportBlockService::class);
+
+$fields = [
+    [
+        'id' => 'company_name',
+        'label' => 'Company Name',
+        'x' => 0,
+        'y' => 0,
+        'width' => 200,
+        'height' => 40,
+    ],
+    [
+        'id' => 'company_address',
+        'label' => 'Company Address',
+        'x' => 0,
+        'y' => 50,
+        'width' => 200,
+        'height' => 60,
+    ],
+];
+
+$service->saveBlockFields($block, $fields);
+```
+
+### Loading Field Configuration
+```php
+$fields = $service->loadBlockFields($block);
+```

+
+## Notes
+
+- All tests are marked as incomplete (`markTestIncomplete()`) by default as requested
+- Tests have working implementations and can be unmarked when ready to run

 - **Use meaningful method names** that describe what they do.
 
+### Internationalization & Translations
+
+**CRITICAL:** InvoicePlane v2 uses `trans()` for all translations, NOT `__()`.
+
+```php
+// ❌ WRONG - Do not use __()
+$label = __('ip.invoice_total');
+
+// ✅ CORRECT - Always use trans()
+$label = trans('ip.invoice_total');
+```
+
+**Translation Key Conventions:**
+- Main translation file: `resources/lang/en/ip.php`
+- Prefix keys with `ip.` (e.g., `ip.invoice_total`, `ip.payment_method`)
+- Use snake_case for key names
+- In Blade: Use `{{ trans('ip.key') }}` or `@lang('ip.key')`
+
+**UI Text Translation Requirements:**
+ALL user-facing text must use trans():
+- Form field labels: `->label(trans('ip.field_label'))`
+- Placeholders: `->placeholder(trans('ip.placeholder'))`
+- Helper text: `->helperText(trans('ip.help_text'))`
+- Section titles: `Section::make(trans('ip.section_title'))`
+- Button labels: `trans('ip.button_text')`
+- Table headers: `trans('ip.column_name')`
+- Tooltips & hints: `trans('ip.tooltip')`
+- Success/error messages: `trans('ip.message')`
+
+**Example:**
+```php
+TextInput::make('name')
+    ->label(trans('ip.report_block_name'))
+    ->placeholder(trans('ip.report_block_name_placeholder'))
+    ->helperText(trans('ip.report_block_name_help'));
+
+Section::make(trans('ip.section_general'))
+    ->schema([...]);
+```
