+# 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);
+```
+

+
+## Future Enhancements
+
+Potential areas for future improvement:
+1. Visual field editor with WYSIWYG preview
+2. Field templates/presets for common layouts
+3. Conditional field visibility based on data
+4. Field validation rules
+5. Custom field types (QR codes, barcodes, charts)
+6. Multi-language field labels
+7. Export/import field configurations
+
+## Notes
+
+- All tests are marked as incomplete (`markTestIncomplete()`) by default as requested
+- Tests have working implementations and can be unmarked when ready to run
+- Field JSON files are stored in `storage/app/report_blocks/` directory
+- Logging can be monitored at `storage/logs/laravel.log`
+- Block widths automatically map to grid columns using `getGridWidth()` method

 - **Extract complex conditions** into well-named methods.
 - **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([...]);
+```

+```php
+// ❌ WRONG - Do not use __()
+$label = __('ip.invoice_total');
+$message = __('ip.payment_successful');
+
+// ✅ CORRECT - Always use trans()
+$label = trans('ip.invoice_total');
+$message = trans('ip.payment_successful');
+```
+
+**Blade Templates:**
+```blade
+{{-- ✅ CORRECT --}}
+{{ trans('ip.total') }}
+@lang('ip.total')  {{-- @lang() is acceptable in Blade --}}
+```
+
+### Translation Key Conventions
+- Main translation file: `resources/lang/en/ip.php`
+- Prefix all keys with `ip.` for InvoicePlane-specific translations
+- Use snake_case for key names
+- Group related translations logically
+- Example keys: `ip.invoice_total`, `ip.payment_method`, `ip.report_field_company_name`
+
+### UI Text Translation Requirements
+**ALL user-facing text must be translatable:**
+
+**Form Fields:**
+```php
+// Labels
+TextInput::make('name')
+    ->label(trans('ip.field_label'))
+
+// Placeholders
+TextInput::make('email')
+    ->placeholder(trans('ip.email_placeholder'))
+
+// Helper Text
+TextInput::make('vat_id')
+    ->helperText(trans('ip.vat_id_help'))
+
+// Section Titles
+Section::make(trans('ip.section_general'))
+```
+
+**Required Translation Coverage:**
+- ✅ Form field labels
+- ✅ Form placeholders
+- ✅ Helper text and hints
+- ✅ Tips and tooltips
+- ✅ Button labels
+- ✅ Section titles
+- ✅ Table column headers
+- ✅ Success/error messages
+- ✅ Validation messages
+- ✅ Menu items
+- ✅ Page titles
+
+### Service Translation Pattern
+When services load translatable content from config files:
+```php
+// Load from config and translate
+$label = trans(config('some-config.label'));
+
+// In service methods
+public function getTranslatedLabel(): string
+{
+    return trans($this->configKey);
+}
+```

-#     - "auth" (from auth.php)
-#   Use case: When you want to add different extension or suffix
-#   Pattern example: /lang/%locale%/%file_name%.json
-#   Result: /lang/de_DE/messages.json (changed extension)
-#
-# %file_extension%
-#   Description: File extension only (without dot)
-#   Examples:
-#     - "php"
-#     - "json"
-#     - "yml"
-#     - "xml"
-#   Use case: Dynamic extension handling
-#   Pattern example: /lang/%locale%/%file_name%.%file_extension%
-#   Result: /lang/de_DE/messages.php
-#
-# %original_path%
-#   Description: Relative path from source, excluding filename
-#   Examples:
-#     - For source: /resources/lang/en/subfolder/file.php
-#     - Result: "subfolder" (path component between source and filename)
-#   Use case: Preserving directory structure from source
-#   Pattern example: /resources/lang/%locale%/%original_path%/%original_file_name%
-#   Result: /resources/lang/de_DE/subfolder/file.php
-#

-# ──────────────────────────────────────────────────────────────────────────
-# LANGUAGE MAPPING REFERENCE (InvoicePlane v1 → Laravel Standard)
-# ──────────────────────────────────────────────────────────────────────────
-#
-# If you need to map Crowdin language codes to Laravel standard format,
-# use the languages_mapping option in your file configuration:
-#
-# Example configuration:
-#   languages_mapping:
-#     locale:

-#       cs: cs_CZ      # Czech
-#       da: da_DK      # Danish
-#       de: de_DE      # German
-#       el: el_GR      # Greek
-#       es-AR: es_AR   # Spanish (Argentina)
-#       es-ES: es_ES   # Spanish (Spain)

-#       it: it_IT      # Italian
-#       ja: ja_JP      # Japanese
-#       ko: ko_KR      # Korean
-#       lt: lt_LT      # Lithuanian
-#       lv: lv_LV      # Latvian
-#       nl: nl_NL      # Dutch
-#       no: no_NO      # Norwegian
-#       pl: pl_PL      # Polish
-#       pt-BR: pt_BR   # Portuguese (Brazil)
-#       pt-PT: pt_PT   # Portuguese (Portugal)
-#       ro: ro_RO      # Romanian
-#       sl: sl_SI      # Slovenian
-#       sq: sq_AL      # Albanian

-#       vi: vi_VN      # Vietnamese
-#       zh-CN: zh_CN   # Chinese (Simplified)
-#
-# Note: With %locale% placeholder, most mappings are automatic.
-# Custom mappings are only needed for special cases or legacy support.

-# ============================================================================
-# NOTES
-# ============================================================================
-# - The project_id and api_token are passed via GitHub Actions secrets
-# - Files are synced bidirectionally: sources uploaded, translations downloaded
-# - Glob patterns (**) match any directory depth, (*) matches within one level
-# - Changes to this file require re-running the Crowdin sync workflow
