# Phase 16 Plan 01: Trade Category Translations Summary

TranslatableModel behavior added to TradeCategory with Polish and German translations seeded for all 36 categories.

## What Was Done

### Task 1: Add TranslatableModel behavior to TradeCategory
Added the Golem15.Translate.Behaviors.TranslatableModel behavior to the TradeCategory model with soft dependency prefix (@). Marked `name` and `description` as translatable fields.

**Key changes:**
- Added `$implement` array with TranslatableModel behavior
- Added `$translatable = ['name', 'description']` property

### Task 2: Seed Polish and German translations
Created migration v1.4.0/add_trade_category_translations.php that seeds translations for all trade categories.

**Categories translated (36 total):**

| Main Category | Polish | German |
|---------------|--------|--------|
| Plumbing | Hydraulika | Sanitaer- und Heizungstechnik |
| Electrical | Elektryka | Elektrik |
| Painting & Decorating | Malowanie i dekoracja | Malerarbeiten |
| Carpentry | Stolarstwo | Tischlerei |
| Roofing | Dekarstwo | Dachdeckerei |
| Masonry | Murarstwo | Maurerarbeiten |
| HVAC | Klimatyzacja i wentylacja | Heizung, Lueftung, Klimatechnik |
| Landscaping | Architektura krajobrazu | Garten- und Landschaftsbau |
| General Repairs | Naprawy ogolne | Allgemeine Reparaturen |

Plus 27 subcategories with appropriate translations.

## Decisions Made

1. **Soft dependency for TranslatableModel**: Using `@` prefix allows TradeCategory to work even if Translate plugin is not installed.

2. **36 categories, not 33**: Actual database has 9 main categories with 3 subcategories each = 36 total (not 33 as estimated in plan).

3. **DB::table() pattern**: Consistent with project decision 11-01, using raw DB queries in seeder to avoid model boot issues during migration.

## Verification Results

```php
// Polish translation
$translator->setLocale('pl');
$cat = TradeCategory::where('slug', 'plumbing')->first();
$cat->name; // "Hydraulika"

// German translation
$translator->setLocale('de');
$cat->name; // "Sanitaer- und Heizungstechnik"

// English (default)
$translator->setLocale('en');
$cat->name; // "Plumbing"
```

## Deviations from Plan

None - plan executed exactly as written.
