## Phase 2 - Catalog Implementation Summary

### Enums (7 files in `/Users/fabianwesner/Herd/shop/app/Enums/`)

| File | Values |
|---|---|
| `ProductStatus.php` | Draft, Active, Archived |
| `VariantStatus.php` | Active, Archived |
| `CollectionStatus.php` | Draft, Active, Archived |
| `CollectionType.php` | Manual, Automated |
| `MediaType.php` | Image, Video |
| `MediaStatus.php` | Processing, Ready, Failed |
| `InventoryPolicy.php` | Deny, Continue |

### Migrations (9 files in `/Users/fabianwesner/Herd/shop/database/migrations/`)

All migrations follow the existing convention with SQLite CHECK constraints implemented via triggers:

| File | Key Features |
|---|---|
| `2025_01_01_000100_create_products_table.php` | FK to stores, unique (store_id, handle), CHECK on status, indexes per spec |
| `2025_01_01_000110_create_product_options_table.php` | FK to products, unique (product_id, position) |
| `2025_01_01_000120_create_product_option_values_table.php` | FK to product_options, unique (product_option_id, position) |
| `2025_01_01_000130_create_product_variants_table.php` | FK to products, CHECK on status, indexes on sku, barcode, position |
| `2025_01_01_000140_create_variant_option_values_table.php` | Composite PK (variant_id, product_option_value_id) |
| `2025_01_01_000150_create_inventory_items_table.php` | FK to stores + variants, unique variant_id, CHECK on policy |
| `2025_01_01_000160_create_collections_table.php` | FK to stores, unique (store_id, handle), CHECK on type and status |
| `2025_01_01_000170_create_collection_products_table.php` | Composite PK (collection_id, product_id), position column |
| `2025_01_01_000180_create_product_media_table.php` | FK to products, CHECK on type and status, created_at only |

### Models (7 files in `/Users/fabianwesner/Herd/shop/app/Models/`)

| Model | Key Features |
|---|---|
| `Product.php` | Uses `BelongsToStore`, `HasFactory`. Relations: `variants()`, `options()`, `media()`, `collections()`. Casts: status (enum), tags (array), published_at (datetime). |
| `ProductOption.php` | No timestamps. Relations: `product()`, `values()`. |
| `ProductOptionValue.php` | No timestamps. Relations: `option()`. |
| `ProductVariant.php` | Relations: `product()`, `inventoryItem()`, `optionValues()`. Casts: status (enum), price_amount (integer), boolean fields. |
| `InventoryItem.php` | Uses `BelongsToStore`. No timestamps. Helper method `availableQuantity()`. Relations: `variant()`. |
| `Collection.php` | Uses `BelongsToStore`. Relations: `products()`. Casts: status (enum), type (enum). |
| `ProductMedia.php` | Only `created_at` (no `updated_at`). Relations: `product()`. Casts: type (enum), status (enum). |

### Factories (7 files in `/Users/fabianwesner/Herd/shop/database/factories/`)

Each factory has meaningful defaults and useful states:
- `ProductFactory` - states: `active()`, `archived()`
- `ProductOptionFactory` - random option names (Size, Color, Material)
- `ProductOptionValueFactory` - random values (Small, Medium, Large, etc.)
- `ProductVariantFactory` - states: `nonDefault()`, `archived()`, `onSale()`, `digital()`
- `InventoryItemFactory` - states: `allowOverselling()`, `outOfStock()`, `withStock()`
- `CollectionFactory` - states: `automated()`, `draft()`, `archived()`
- `ProductMediaFactory` - states: `processing()`, `failed()`, `video()`

### Services (3 files in `/Users/fabianwesner/Herd/shop/app/Services/`)

**`ProductService.php`** (`/Users/fabianwesner/Herd/shop/app/Services/ProductService.php`)
- `create(Store, array): Product` - creates product with default variant + inventory item, auto-generates handle
- `update(Product, array): Product` - updates product, regenerates handle when title changes
- `transitionStatus(Product, ProductStatus): void` - full state machine validation per spec
- `delete(Product): void` - only draft with no order references

**`VariantMatrixService.php`** (`/Users/fabianwesner/Herd/shop/app/Services/VariantMatrixService.php`)
- `rebuildMatrix(Product): void` - computes cartesian product of option values, preserves existing matching variants (prices, SKUs, inventory intact), deletes orphans without order refs, archives orphans with order refs, ensures default variant when no options exist

**`InventoryService.php`** (`/Users/fabianwesner/Herd/shop/app/Services/InventoryService.php`)
- `checkAvailability(InventoryItem, int): bool` - respects deny/continue policy
- `reserve(InventoryItem, int): void` - increments reserved, throws `InsufficientInventoryException` for deny policy
- `release(InventoryItem, int): void` - decrements reserved
- `commit(InventoryItem, int): void` - decrements both on_hand and reserved
- `restock(InventoryItem, int): void` - increments on_hand
- All operations wrapped in DB transactions

### Support Class

**`HandleGenerator.php`** (`/Users/fabianwesner/Herd/shop/app/Support/HandleGenerator.php`)
- `generate(string $title, string $table, int $storeId, ?int $excludeId): string` - slugifies title, checks uniqueness per store, appends -1, -2 on collision

### Exceptions (2 files in `/Users/fabianwesner/Herd/shop/app/Exceptions/`)

- `InsufficientInventoryException.php` - includes variantId, requestedQuantity, availableQuantity
- `InvalidProductTransitionException.php` - includes fromStatus, toStatus, reason

### Job

**`ProcessMediaUpload.php`** (`/Users/fabianwesner/Herd/shop/app/Jobs/ProcessMediaUpload.php`)
- Implements `ShouldQueue`, 3 retry attempts
- Updates media status from `processing` to `ready` (placeholder for future image resizing)
- Sets status to `failed` on error

### Tests (6 files, 50 tests, 80 assertions - all passing)

| Test File | Tests | Coverage |
|---|---|---|
| `ProductServiceTest.php` | 10 | Product CRUD, status transitions, handle generation, deletion rules |
| `InventoryServiceTest.php` | 10 | All inventory operations, policy enforcement, exception handling |
| `VariantMatrixServiceTest.php` | 5 | Default variant creation, single/multiple options, preservation, orphan cleanup |
| `HandleGeneratorTest.php` | 7 | Slug generation, collisions, suffixes, exclusion, cross-store isolation, edge cases |
| `ProductModelTest.php` | 15 | All model relationships, enum casts, boolean casts, pivot tables |
| `ProcessMediaUploadTest.php` | 3 | Status update, skip non-processing, handle missing media |</result>
