Vendra Currency

Workflow

Unexpected resolver and query failures are reported through Laravel before returning currency defaults. Missing providers, empty catalogs, and tables awaiting migration remain quiet fallbacks.
Own the concrete Misaf\VendraCurrency\Support\EloquentCurrencyResolver adapter here and bind it to Support's CurrencyResolver contract. Preserve configurable models and columns, active filtering, default selection, tenant isolation, and fallback behavior. Consumers depend on the shared contract rather than this adapter.
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-currency 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.
Keep currencies out of TenantTableRegistry: its null tenant id is a platform currency, and vendra-tenant:enable {tenant} would backfill those rows and force the column NOT NULL. Register any new tenant-only table (a non-nullable TenantSchema::addTenantColumn()) there, preserving configured table names and connections.

Module Boundary

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

Use namespace Misaf\VendraCurrency.
Keep domain models, factories, seeders, policies, observers, console commands, Filament classes, config, migrations, translations, and tests inside this module.
Do not place currency domain code in the host app unless the host app is only integrating the module.
Keep cross-module dependencies explicit in composer.json; do not introduce a dependency without approval.

Domain Model Standards

Follow the existing Currency model pattern for new currency entities. The catalog of installable currencies lives in Support\CurrencyRegistry (moneyphp ISO + crypto data); rows snapshot code, name, symbol, decimal_places, and type at install time. Exactly one enabled currency is the default, enforced by the default_guard unique index, CurrencyObserver, and the locked SetDefaultCurrencyAction action.

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.
Tenantless currencies rows are the platform's currencies (the console's, for plans and reseller wallets); each tenant keeps its own set and default. Outside a tenant, the install and default actions, CurrencyForm and the bound CurrencyResolver work on the platform rows through TenantAwareness::constrainToCurrentTenant(), and Currency::query()->platform() reaches them from inside a tenant too. Keep the platform_code_guard and platform_default_guard unique columns in the migration. Pass the authorizing resource to CurrencyTable::configure(), InstallCurrenciesTableAction::make() and SetDefaultCurrencyTableAction::make() rather than checking the policy directly.
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\VendraCurrency\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-currency::attributes, vendra-currency::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-currency.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.
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\VendraCurrency')->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-currency and composer stan.
If PHP files changed, run Pint for the touched code: vendor/bin/pint --dirty --format agent from the host app.
