# Vendra Product ## Workflow - Inspect `composer.json`, sibling files, and existing tests before changing the package. - Use Laravel Boost `application-info` and `search-docs` before code changes. - Apply `laravel-best-practices` to Laravel PHP and `pest-testing` whenever tests change. - Apply `tailwindcss-development` only when changing Blade markup or Tailwind classes. - Keep changes inside this package's boundary and preserve its public contracts. - Add or update focused Pest coverage, then run `php artisan test --compact --testsuite=vendra-product` and `composer stan`. ## Translatable Persistence - Making a persisted model field translatable is an explicit domain choice unless this package already requires it. - Every field listed in a model's `$translatable` array must definitely use a JSON database column. Keep its model traits/casts, factories, validation, Filament locale UI, API serialization, and tests translation-aware. - A field not listed in `$translatable` must use the appropriate scalar database type and must not use Spatie Translatable, translatable slug traits, locale switchers, translated callbacks, or translation-shaped array data. ## Vendra Transitive API Policy - Treat a Vendra dependency intentionally exposed through the public API of a directly required Vendra platform package as part of the supported public contract of that package. - Do not add a redundant direct Composer requirement solely because source code imports a type from that exposed dependency. - Apply this only to Vendra platform packages listed under `require`; never extend it to `require-dev`, `suggest`, incidental implementation dependencies, or third-party packages. Removing or replacing an exposed dependency is a breaking change; keep `self.version` alignment across the Vendra package graph. - Register every table whose migration calls `TenantSchema::addTenantColumn()` with `TenantTableRegistry` in this package's service provider, preserving configured table names and connections, so `vendra-tenant:enable {tenant}` can retrofit schemas migrated before tenancy was enabled. - Creating a product counts against the store plan's `PlanLimit::ProductsPerStore`: the provider registers the `TenantUsageRegistry` counter, `ProductLifecycleObserver::creating` refuses a product past the limit on every path, `CreateProduct` shows the refusal as a notification, and `Actions\Concerns\DisablesAtProductLimit` disables `CreateProductPageAction` and `DuplicateProductTableAction` with the refusal as a tooltip at the cap. `ProductLifecycleObserver::created()` reports each add with `recordAdded()`. ## Module Boundary Treat `packages/vendra-product` as the source of product domain behavior and Filament admin UI. - Use namespace `Misaf\VendraProduct`. - Keep domain models, factories, seeders, policies, observers, console commands, Filament classes, config, migrations, translations, and tests inside this module. - Do not place product domain code in the host app unless the host app is only integrating the module. - Keep API serialization and API Platform route behavior out of this module; use `vendra-product-api` for that. - Purchase eligibility and catalog pricing live in `Services\ProductPurchaseQuoter`, which batches its product query and returns typed `ProductPurchaseQuote` results or `ProductPurchaseRefusalEnum` cases. It charges the newest price row in the currency; prices are append-only history. It must not import cart, order, or API types. - Stock moves only through `Actions\DeductProductStockAction` (locked in id order, all or nothing, `InsufficientProductStockException`, `in_stock` off with the last unit; restocking never turns it back on) and `Actions\RestockProductsAction`. - Product duplication lives entirely in `Actions\DuplicateProductAction` (unique copy names and slugs per tenant, prices, media, attribute selections, tags); the Filament table action only delegates to it. - Keep cross-module dependencies explicit in `composer.json`; do not introduce a dependency without approval. - Tag-consuming models must use `Misaf\VendraSupport\Capabilities\HasOptionalTags` as the single source of their `tags()` relationship and pivot metadata. Keep the package tag-agnostic: define a stable package-owned tag type, use `TagIntegration` for availability and UI integration, never import the concrete Vendra Tagger model/provider or define the relationship through Spatie `HasTags`, and list Tagger only under Composer `suggest`. ## Domain Model Standards Follow the existing `Product` and `ProductCategory` patterns for new product entities. - Use `declare(strict_types=1)`, final classes, typed method signatures, and PHPDoc generics for relationships. - Follow Laravel comment style: document with PHPDoc (array shapes, generics, `@see`) and reserve inline comments for genuinely complex logic. Match the surrounding file's density and do not add comments that restate the code. - Prefer the Laravel attributes already used here, such as `#[Fillable]`, `#[Hidden]`, `#[UseFactory]`, and `#[ObservedBy]`. - Keep the module tenant-agnostic: derive tenant awareness purely from the bound `TenantResolver` in `misaf/vendra-support` (`TenantAwareness`, `BelongsToTenant`, `TenantSchema`, `RequiresCurrentTenant`). The module must build and run whether or not a tenant provider is installed, so never reference a concrete provider such as `Misaf\VendraTenant` anywhere — models, migrations, factories, seeders, or fixtures. There is no `tenant_aware` config toggle. - Hide `tenant_id` and keep tenant behavior centralized in the support layer; do not duplicate tenant scoping or `tenant_id` assignment in models, Filament resources, factories, or seeders. `BelongsToTenant` assigns `tenant_id` on `creating` from the current tenant. - Reuse only the traits and conventions present on the affected sibling model; do not infer translations, media, slugs, sorting, or soft deletes from another package. ## Filament Standards Keep every resource that declares a `$cluster`, including its complete supporting tree, under `src/Filament/Clusters/Resources/` with the matching `Misaf\VendraProduct\Filament\Clusters\Resources` namespace and plugin discovery path. Resources without a cluster belong under `src/Filament/Resources/`. - Register module UI through the module `Plugin` and `ServiceProvider`; do not manually wire resources in unrelated panel providers. - Keep resource classes thin. Delegate form schemas to `Schemas/*Form.php` and table configuration to `Tables/*Table.php`. - Use Filament v5 namespaces: form fields from `Filament\Forms\Components`, layout from `Filament\Schemas\Components`, table columns from `Filament\Tables\Columns`, filters from `Filament\Tables\Filters`, actions from `Filament\Actions`, and icons from `Filament\Support\Icons\Heroicon`. - Use this module's translation keys (`vendra-product::attributes`, `vendra-product::navigation`) for labels, breadcrumbs, and navigation. - Keep cluster resources ungrouped and assign `$navigationSort` from their package-specific `NavigationPriority` cases; never hardcode numeric resource sort values. - Provide separate singular and plural resource labels in `en`, `de`, and `fa`: model labels use the singular key, while navigation and plural model labels use the plural key. Keep navigation labels at 24 characters or fewer. - Prevent N+1 issues in tables and relation managers with eager loading, `withCount`, or computed state based on loaded relationships. - Use public media visibility only when public access is actually required. ## Permissions And Navigation Use policy enums and policies as the permission source. - Add enum cases for every resource action the panel exposes. - Keep policy method names aligned with Filament actions: `viewAny`, `view`, `create`, `update`, `delete`, `deleteAny`, `restore`, `restoreAny`, `forceDelete`, `forceDeleteAny`, `replicate`, and `reorder` as applicable. - Update `PermissionPolicySeeder` when new permissions are introduced. - Keep navigation labels and groups configurable through the module `Plugin` and `config/vendra-product.php`. Do not add a `tenant_aware` config value; tenant awareness derives from the bound `TenantResolver`. ## Data And Localization Migrations, factories, seeders, and translation files are part of the contract. - Use package migrations in `database/migrations`, with stubs only when the install flow expects publishing. - Use factories under `database/factories` and seeders under `database/seeders`. Keep them tenant-safe: import no concrete tenant provider and set no `tenant_id` directly; let `BelongsToTenant` assign it from the current tenant so they work with tenancy on or off. - Keep demo fixtures deterministic and tenant-safe. - Update all supported locales together and keep translation keys sorted. - Preserve translation key parity tests when adding labels or attributes. ## Testing And Verification Prefer focused Pest tests in the module. - Keep tests purposeful and prevent unnecessary ones: cover behavior, contracts, and edge cases — not framework internals or trivially typed code. Do not duplicate coverage a focused test already proves, and do not add throwaway verification scripts (or `tinker`) when a test fits. - Keep an architecture expectation proving Product does not use Vendra Tagger or Spatie Tags directly. Test both the unavailable fallback and the support-resolved polymorphic relation. - Add or update unit tests for model contracts, policy permission coverage, resolver-derived tenant awareness, navigation/config behavior, and translation parity. - Keep Pest architecture tests in `tests/ArchTest.php`: the `php`, `security`, and `laravel` presets, plus an expectation that the module stays tenant-agnostic, e.g. `arch()->expect('Misaf\VendraProduct')->not->toUse('Misaf\VendraTenant')`. - Add feature or Livewire tests when changing Filament behavior with meaningful user-visible effects. - Run checks from the host app: `php artisan test --compact --testsuite=vendra-product` and `composer stan`. - If PHP files changed, run Pint for the touched code: `vendor/bin/pint --dirty --format agent` from the host app. - Demo seeders declare their factory dependencies in `FACTORIES`; the shared base uses bundled fixtures when any declared factory is unavailable, including standalone Composer installs. Keep factories in development autoloading. - `Support\ProductStockRestorer` binds `Misaf\VendraSupport\Contracts\StockRestorer`, supplies Product’s morph alias, and delegates restoration to `RestockProductsAction`. It preserves tenant scoping, restores soft-deleted products, and leaves `in_stock` unchanged. Product imports no Order or Order API types.

Vendra Product

Workflow

Inspect composer.json, sibling files, and existing tests before changing the package.
Use Laravel Boost application-info and search-docs before code changes.
Apply laravel-best-practices to Laravel PHP and pest-testing whenever tests change.
Apply tailwindcss-development only when changing Blade markup or Tailwind classes.
Keep changes inside this package's boundary and preserve its public contracts.
Add or update focused Pest coverage, then run php artisan test --compact --testsuite=vendra-product and composer stan.

Translatable Persistence

Making a persisted model field translatable is an explicit domain choice unless this package already requires it.
Every field listed in a model's $translatable array must definitely use a JSON database column. Keep its model traits/casts, factories, validation, Filament locale UI, API serialization, and tests translation-aware.
A field not listed in $translatable must use the appropriate scalar database type and must not use Spatie Translatable, translatable slug traits, locale switchers, translated callbacks, or translation-shaped array data.

Vendra Transitive API Policy

Treat a Vendra dependency intentionally exposed through the public API of a directly required Vendra platform package as part of the supported public contract of that package.
Do not add a redundant direct Composer requirement solely because source code imports a type from that exposed dependency.
Apply this only to Vendra platform packages listed under require; never extend it to require-dev, suggest, incidental implementation dependencies, or third-party packages. Removing or replacing an exposed dependency is a breaking change; keep self.version alignment across the Vendra package graph.
Register every table whose migration calls TenantSchema::addTenantColumn() with TenantTableRegistry in this package's service provider, preserving configured table names and connections, so vendra-tenant:enable {tenant} can retrofit schemas migrated before tenancy was enabled.
Creating a product counts against the store plan's PlanLimit::ProductsPerStore: the provider registers the TenantUsageRegistry counter, ProductLifecycleObserver::creating refuses a product past the limit on every path, CreateProduct shows the refusal as a notification, and Actions\Concerns\DisablesAtProductLimit disables CreateProductPageAction and DuplicateProductTableAction with the refusal as a tooltip at the cap. ProductLifecycleObserver::created() reports each add with recordAdded().

Module Boundary

Treat packages/vendra-product as the source of product domain behavior and Filament admin UI.

Use namespace Misaf\VendraProduct.
Keep domain models, factories, seeders, policies, observers, console commands, Filament classes, config, migrations, translations, and tests inside this module.
Do not place product domain code in the host app unless the host app is only integrating the module.
Keep API serialization and API Platform route behavior out of this module; use vendra-product-api for that.
Purchase eligibility and catalog pricing live in Services\ProductPurchaseQuoter, which batches its product query and returns typed ProductPurchaseQuote results or ProductPurchaseRefusalEnum cases. It charges the newest price row in the currency; prices are append-only history. It must not import cart, order, or API types.
Stock moves only through Actions\DeductProductStockAction (locked in id order, all or nothing, InsufficientProductStockException, in_stock off with the last unit; restocking never turns it back on) and Actions\RestockProductsAction.
Product duplication lives entirely in Actions\DuplicateProductAction (unique copy names and slugs per tenant, prices, media, attribute selections, tags); the Filament table action only delegates to it.
Keep cross-module dependencies explicit in composer.json; do not introduce a dependency without approval.
Tag-consuming models must use Misaf\VendraSupport\Capabilities\HasOptionalTags as the single source of their tags() relationship and pivot metadata. Keep the package tag-agnostic: define a stable package-owned tag type, use TagIntegration for availability and UI integration, never import the concrete Vendra Tagger model/provider or define the relationship through Spatie HasTags, and list Tagger only under Composer suggest.

Domain Model Standards

Follow the existing Product and ProductCategory patterns for new product entities.

Use declare(strict_types=1), final classes, typed method signatures, and PHPDoc generics for relationships.
Follow Laravel comment style: document with PHPDoc (array shapes, generics, @see) and reserve inline comments for genuinely complex logic. Match the surrounding file's density and do not add comments that restate the code.
Prefer the Laravel attributes already used here, such as #[Fillable], #[Hidden], #[UseFactory], and #[ObservedBy].
Keep the module tenant-agnostic: derive tenant awareness purely from the bound TenantResolver in misaf/vendra-support (TenantAwareness, BelongsToTenant, TenantSchema, RequiresCurrentTenant). The module must build and run whether or not a tenant provider is installed, so never reference a concrete provider such as Misaf\VendraTenant anywhere — models, migrations, factories, seeders, or fixtures. There is no tenant_aware config toggle.
Hide tenant_id and keep tenant behavior centralized in the support layer; do not duplicate tenant scoping or tenant_id assignment in models, Filament resources, factories, or seeders. BelongsToTenant assigns tenant_id on creating from the current tenant.
Reuse only the traits and conventions present on the affected sibling model; do not infer translations, media, slugs, sorting, or soft deletes from another package.

Filament Standards

Keep every resource that declares a $cluster, including its complete supporting tree, under src/Filament/Clusters/Resources/ with the matching Misaf\VendraProduct\Filament\Clusters\Resources namespace and plugin discovery path. Resources without a cluster belong under src/Filament/Resources/.

Register module UI through the module Plugin and ServiceProvider; do not manually wire resources in unrelated panel providers.
Keep resource classes thin. Delegate form schemas to Schemas/*Form.php and table configuration to Tables/*Table.php.
Use Filament v5 namespaces: form fields from Filament\Forms\Components, layout from Filament\Schemas\Components, table columns from Filament\Tables\Columns, filters from Filament\Tables\Filters, actions from Filament\Actions, and icons from Filament\Support\Icons\Heroicon.
Use this module's translation keys (vendra-product::attributes, vendra-product::navigation) for labels, breadcrumbs, and navigation.
Keep cluster resources ungrouped and assign $navigationSort from their package-specific NavigationPriority cases; never hardcode numeric resource sort values.
Provide separate singular and plural resource labels in en, de, and fa: model labels use the singular key, while navigation and plural model labels use the plural key. Keep navigation labels at 24 characters or fewer.
Prevent N+1 issues in tables and relation managers with eager loading, withCount, or computed state based on loaded relationships.
Use public media visibility only when public access is actually required.

Permissions And Navigation

Use policy enums and policies as the permission source.

Add enum cases for every resource action the panel exposes.
Keep policy method names aligned with Filament actions: viewAny, view, create, update, delete, deleteAny, restore, restoreAny, forceDelete, forceDeleteAny, replicate, and reorder as applicable.
Update PermissionPolicySeeder when new permissions are introduced.
Keep navigation labels and groups configurable through the module Plugin and config/vendra-product.php. Do not add a tenant_aware config value; tenant awareness derives from the bound TenantResolver.

Data And Localization

Migrations, factories, seeders, and translation files are part of the contract.

Use package migrations in database/migrations, with stubs only when the install flow expects publishing.
Use factories under database/factories and seeders under database/seeders. Keep them tenant-safe: import no concrete tenant provider and set no tenant_id directly; let BelongsToTenant assign it from the current tenant so they work with tenancy on or off.
Keep demo fixtures deterministic and tenant-safe.
Update all supported locales together and keep translation keys sorted.
Preserve translation key parity tests when adding labels or attributes.

Testing And Verification

Prefer focused Pest tests in the module.

Keep tests purposeful and prevent unnecessary ones: cover behavior, contracts, and edge cases — not framework internals or trivially typed code. Do not duplicate coverage a focused test already proves, and do not add throwaway verification scripts (or tinker) when a test fits.
Keep an architecture expectation proving Product does not use Vendra Tagger or Spatie Tags directly. Test both the unavailable fallback and the support-resolved polymorphic relation.
Add or update unit tests for model contracts, policy permission coverage, resolver-derived tenant awareness, navigation/config behavior, and translation parity.
Keep Pest architecture tests in tests/ArchTest.php: the php, security, and laravel presets, plus an expectation that the module stays tenant-agnostic, e.g. arch()->expect('Misaf\VendraProduct')->not->toUse('Misaf\VendraTenant').
Add feature or Livewire tests when changing Filament behavior with meaningful user-visible effects.
Run checks from the host app: php artisan test --compact --testsuite=vendra-product and composer stan.
If PHP files changed, run Pint for the touched code: vendor/bin/pint --dirty --format agent from the host app.
Demo seeders declare their factory dependencies in FACTORIES; the shared base uses bundled fixtures when any declared factory is unavailable, including standalone Composer installs. Keep factories in development autoloading.
Support\ProductStockRestorer binds Misaf\VendraSupport\Contracts\StockRestorer, supplies Product’s morph alias, and delegates restoration to RestockProductsAction. It preserves tenant scoping, restores soft-deleted products, and leaves in_stock unchanged. Product imports no Order or Order API types.
