Server-side nopCommerce plugin for FruitBank, a fruit and vegetable wholesaler. Manages supplier inbound delivery (receiving), warehouse weighing (net/gross/pallet/tare weights), outbound order measurement, inventory stocktaking, AI services, and Billingo invoicing. Runs inside nopCommerce 4.80.9 (**net9.0**).

Project file: `Nop.Plugin.Misc.FruitBankPlugin.csproj`

## Dependencies

- `Mango.Nop.Core`, `Mango.Nop.Services` (ProjectReferences via `../../Libraries/`)
- `Nop.Services`, `Nop.Web` (nopCommerce ProjectReferences)
- AyCode.Core solution assemblies (DLL HintPaths in .csproj)
- DevExpress ASP.NET Core 25.1.3, DevExtreme 25.1.3
- SignalR, EF Core 9.0, PdfPig, PDFtoImage

## Initialization & Quirks

- **AcBinary Source Generator Registration**: NopCommerce plugins are loaded dynamically via `AssemblyLoadContext`, which prevents the .NET runtime from executing `[ModuleInitializer]` attributes. To ensure the high-performance binary serializers are registered (instead of falling back to slow reflection), `PluginNopStartup.ConfigureServices` must call `Mango.Nop.Core.AcBinaryForcedInit.ForceRegister()`.

## Type-Location Map

Quick lookup for "where does this type live?" — saves cross-repo grep rounds.

| Type / class family | Lives in | Path (relative or NuGet) |
|---|---|---|
| `Customer`, `Order`, `OrderItem`, `OrderNote`, `Product`, `GenericAttribute`, `CustomerRole` | nopCommerce framework | `Nop.Core` (ProjectRef) |
| `*Dto` classes (`OrderDto`, `OrderItemDto`, `ProductDto`, `GenericAttributeDto`, `StockQuantityHistoryDto`) | Mango.Nop.Core | `../../Libraries/Mango.Nop.Core/` |
| `MgDbContextBase`, `MgDbTableBase<T>`, `MgEventConsumerBase`, other `Mg*` base types | Mango.Nop.* libraries | `../../Libraries/Mango.Nop.{Core,Services,Data}/` |
| `Ac*` types (`AcBinaryHubProtocol`, `AcBinarySerializer`, `AcLoggerBase`, `AcBinaryForcedInit`) | AyCode.Core (DLL HintPath) | `../../../Aycode/Source/AyCode.Core/` |
| `fb*`-table entities: `Shipping`, `ShippingDocument`, `ShippingItem`, `ShippingItemPallet`, `OrderItemPallet`, `StockTaking`, `StockTakingItem`, `StockTakingItemPallet`, `Partner`, `Files`, `Pallet` | this plugin | `Domains/...` (full schema in `docs/SCHEMA.md`) |
| `FullProcessModel` (bulk SignalR sync container) | this plugin | `Models/` |
| `FruitBankDbContext`, `StockTakingDbContext`, `*DbTable` repositories (`OrderDtoDbTable`, `ShippingDbTable`, …), `I*DbSet` interfaces | this plugin | `Domains/DataLayer/` |
| `FruitBankEventConsumer`, `MeasurementService`, `CustomPriceCalculationService`, `FruitBankAttributeService` | this plugin | `Domains/EventConsumers/`, `Services/` |
| AI: `OpenAIApiService`, `CerebrasAPIService`, `ReplicateService`, `OpenAIService`, `AICalculationService` | this plugin | `Services/` |
| File / PDF / Audio: `FileStorageService`, `LocalStorageProvider`, `PdfToImageService`, `FruitBankAudioController` | this plugin | `Services/`, `Controllers/` |
| Billingo: `InnVoiceOrderService`, `InnvoiceApiService` (+ `InnVoiceOrderController`, `InnVoiceOrderSyncController`) | this plugin | `Services/`, `Areas/Admin/Controllers/` |
| SignalR: `FruitBankHub`, `CustomOrderSignalREndpoint`, `StockSignalREndpointServer`, `FruitBankDataController` | this plugin | `Services/`, `Areas/Admin/Controllers/`, `Controllers/` |
| Infra: `FruitBankSettings`, `PluginNopStartup`, `RouteProvider`, `ViewLocationExpander`, `PendingMeasurementCheckoutFilter` | this plugin | `Infrastructure/`, `Filters/` |

If a type isn't listed: grep `../../Libraries/` first → `../../../Aycode/Source/AyCode.Core/` next → otherwise it's a nopCommerce framework type (`Nop.Core`, `Nop.Services`, `Nop.Web`).
