Enforce doc-first protocol, add SGen, modular plugin docs

- Enforced strict documentation-first AI agent protocol in `.github/copilot-instructions.md` (multi-repo, no auto doc edits, explicit consent, [LOADED_DOCS] prefix, [DOCUMENTATION CHECK] on code changes)
- Updated solution structure: added `docs` folder to solution items for LLM/AI context
- Integrated AyCode SGen (source-generated binary serialization) with forced runtime registration; documented SGen usage and exclusions
- Overhauled plugin `README.md` and added modular docs: `SCHEMA.md`, `DOMAIN_MODEL.md`, `MEASUREMENT.md`, `DATA_LAYER.md`, `AI_SERVICES.md`, `SIGNALR_ENDPOINTS.md`
- Updated `CLAUDE.md` to require reading copilot instructions first
- Switched appsettings connection string to production DB
- Minor doc clarifications, corrects, and project file updates

## Dependencies
- `Mango.Nop.Core`, `Mango.Nop.Services` (ProjectReferences via `../../Libraries/`)
- `Nop.Services`, `Nop.Web` (nopCommerce ProjectReferences)
- DevExpress ASP.NET Core 25.1.3
- 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()`.

# Data Layer
> Part of `Nop.Plugin.Misc.FruitBankPlugin`. See `README.md` for project overview.
> For entity model see `docs/DOMAIN_MODEL.md`.
> For measurement workflows see `docs/MEASUREMENT.md`.
## DbContext Classes
### FruitBankDbContext

All state-changing operations wrapped in `TransactionSafeAsync()` for ACID compliance.
### StockTakingDbContext
Inherits `MgDbContextBase`. Dedicated context for inventory sessions.
**DbSet properties:**
| DbSet | Entity |
|---|---|
| `ProductDtos` | ProductDto |
| `OrderItemDtos` | OrderItemDto |
| `StockTakings` | StockTaking |

| `AddStockTakingItemPallet()` / `UpdateStockTakingItemPallet()` | Pallet CRUD with measured values refresh |
| `RefreshStockTakingItemMeasuredValuesFromPallets()` | Sums quantities/weights from pallets |
## DbTable Repositories
Each entity has a `*DbTable` class inheriting `MgDbTableBase<T>` (from `Mango.Nop.Data`). Located in `Domains/DataLayer/`.
### ShippingDbTable
| Method | Purpose |
|---|---|
| `GetAll()` | All shippings ordered by ShippingDate |
| `GetAll(bool loadRelations)` | Eager loads full graph: Documents → Items → Pallets + Pallet type + ProductDto + GenericAttributes |
| `GetAllNotMeasured()` | Filters for incomplete/recent shipments |
| `GetByIdAsync(bool loadRelations)` | Single with optional eager loading |
| `OnUpdate()` | Hook: sets `MeasuredDate` when `IsAllMeasured` becomes true |
### OrderDtoDbTable
| Method | Purpose |
|---|---|
| `GetAll(bool loadRelations)` | Eager loads: GenericAttributes, Customer, OrderNotes, OrderItemDtos (with ProductDto, GenericAttributes, OrderItemPallets) |
| `GetByIdAsync(bool loadRelations)` | Single order with optional relations |
| `GetAllByOrderStatus()` | Status-filtered query |
| `GetAllForMeasuring(DateTime fromDate)` | Unpaid, not cancelled, with DateOfReceipt >= fromDate |
| `GetAllByProductId()` / `GetAllByProductIds()` | Product-filtered queries |
| `GetAllByIds()` | Batch retrieval |
### Other DbTable classes
| Class | Entity | Key behaviors |
|---|---|---|
| `ProductDtoDbTable` | ProductDto | GetAll with GenericAttributes |
| `PartnerDbTable` | Partner | Standard CRUD |
| `ShippingDocumentDbTable` | ShippingDocument | GetAll with items, files, partner |
| `ShippingItemDbTable` | ShippingItem | GetAll with pallets |
| `ShippingItemPalletDbTable` | ShippingItemPallet | Standard CRUD |
| `OrderItemDtoDbTable` | OrderItemDto | GetAll with pallets, product |
| `OrderItemPalletDbTable` | OrderItemPallet | Standard CRUD |
| `FilesDbTable` | Files | Standard CRUD |
| `ShippingDocumentToFilesDbTable` | ShippingDocumentToFiles | Standard CRUD |
| `StockTakingDbTable` | StockTaking | GetAll with items, pallets |
| `StockTakingItemDbTable` | StockTakingItem | GetAll with pallets |
| `StockTakingItemPalletDbTable` | StockTakingItemPallet | Standard CRUD |
| `StockQuantityHistoryDtoDbTable` | StockQuantityHistoryDto | Filtered by date range |
## Repository Interfaces
Located in `Domains/DataLayer/Interfaces/`. Each interface (e.g., `IShippingDbSet`, `IOrderDtoDbSet`) declares the DbSet property that the DbContext must implement. This allows DbTable classes to accept any context that provides the required DbSet.
## Entity Mapping
- `Mapping/Builders/PluginBuilder.cs` — EF Core Fluent API entity configuration for plugin-owned tables (fb* prefix)
- `Mapping/NameCompatibility.cs` — Table name mapping for nopCommerce compatibility
- `Migrations/SchemaMigration.cs` — FluentMigrator schema setup for `CustomTable` base entity
## FruitBankEventConsumer
Located in `Domains/EventConsumers/`. Extends `MgEventConsumerBase` (from `Mango.Nop.Services`). Handles entity lifecycle events for cascading updates.
**Product events:**
| Event | Action |
|---|---|
| `EntityInsertedEvent<Product>` | Saves custom attributes (IsMeasurable, NetWeight, Tare, AverageWeight, AverageWeightTreshold, IncomingQuantity) |
| `EntityUpdatedEvent<Product>` | Updates custom attributes, syncs IsMeasurable/Tare changes to existing ShippingItems |
**Shipping cascade events:**
| Event | Action |
|---|---|
| `EntityDeletedEvent<ShippingItemPallet>` | Refreshes parent ShippingItem measuring values |
| `EntityInsertedEvent/UpdatedEvent<ShippingItem>` | Rechecks ShippingDocument.IsAllMeasured |
| `EntityInsertedEvent/UpdatedEvent<ShippingDocument>` | Rechecks Shipping.IsAllMeasured |
| `EntityDeletedEvent<Shipping>` | Cascade deletes child documents |
| `EntityDeletedEvent<ShippingDocument>` | Cascade deletes child items |
| `EntityDeletedEvent<ShippingItem>` | Cascade deletes child pallets |
**Order events:**
| Event | Action |
|---|---|
| `EntityDeletedEvent<OrderItem>` | Cleanup via `MeasurementService.DeleteOrderItemConstraintsAsync()` |
| `EntityInsertedEvent/UpdatedEvent<OrderItem>` | Post-process via `MeasurementService.OrderItemInsertedOrUpdatedPostProcess()` |
## Eager Loading Pattern
DbTable `GetAll(bool loadRelations = true)` uses `LoadWith()` chains to eagerly load entity graphs. Example for OrderDtoDbTable:
```
OrderDto
→ GenericAttributes
→ Customer
→ OrderNotes
→ OrderItemDtos
→ ProductDto → GenericAttributes
→ GenericAttributes
→ OrderItemPallets
```
This avoids N+1 queries when transferring full entity graphs to FruitBankHybridApp via SignalR.

# Domain Model — Behavioral Documentation
> Part of `Nop.Plugin.Misc.FruitBankPlugin`. See `README.md` for project overview.
> For entity definitions, properties, and relationships see `docs/SCHEMA.md` (authoritative TOON schema).
> For measurement workflows see `docs/MEASUREMENT.md`.
> For data layer details see `docs/DATA_LAYER.md`.
> For core measurement system rules and common domain traps, see: `../../../../../FruitBankHybridApp/FruitBank.Common/docs/GLOSSARY.md`
This document explains **how the domain model behaves** in the plugin. For **what the entities are** (properties, types, relationships), see `docs/SCHEMA.md`.
## Weight Formula
All three pallet types (ShippingItemPallet, OrderItemPallet, StockTakingItemPallet) use the same formula:
```
NetWeight = GrossWeight - PalletWeight - (TrayQuantity * TareWeight)
```
| Field | Meaning |
|---|---|
| `GrossWeight` | Scale reading (total weight). 0.0 if product is not measurable |
| `PalletWeight` | Weight of the physical pallet. 0.0 if goods arrive without pallet |
| `TareWeight` | Weight of one tray/crate (per unit) |
| `TrayQuantity` | Number of trays/crates. Always recorded, even for non-measurable products |
| `NetWeight` | Computed, read-only, not-mapped (setter exists for shared interface but throws Exception) |
## MeasuringStatus Lifecycle
```
NotStarted (0) → Started (10) → Finnished (20) → Audited (30)
[no record] [record created] [IsMeasured=true] [RevisorId > 0]
```
- **NotStarted**: No pallet record exists yet
- **Started**: Pallet record created (Id > 0) but `IsMeasured = false`
- **Finnished**: `IsMeasured = true` — weights recorded
- **Audited**: `RevisorId > 0` — quality auditor confirmed (OrderItemPallet only)
## IsMeasurable Flag
`ProductDto.IsMeasurable` is the master toggle (stored as GenericAttribute). When `false`:
- Weight validation is bypassed
- One pallet record is still created with `GrossWeight = 0.0`
- Only `TrayQuantity` is recorded
- Product is not included in average weight checks
## GenericAttribute Keys
Custom product/order properties are stored via nopCommerce's GenericAttribute table. The DTO classes expose these as computed, not-mapped properties.
### Product attributes (saved by FruitBankEventConsumer)
| Key | Type | Purpose |
|---|---|---|
| `IsMeasurable` | bool | Master flag for weight validation |
| `NetWeight` | double | Product net weight |
| `Tare` | double | Tare weight per tray |
| `AverageWeight` | double | Expected average weight per tray |
| `AverageWeightTreshold` | double | Max allowed deviation % from AverageWeight |
| `IncomingQuantity` | int | Incoming stock not yet received |
### Order attributes
| Key | Type | Purpose |
|---|---|---|
| `DateOfReceipt` | DateTime | Scheduled delivery date |
| `MeasurementOwnerId` | int | User who started measuring |
| `RevisorId` | int | Quality auditor user ID |
## Entity Hierarchy Overview
### Inbound Delivery (Shipping)
```
Shipping (fbShipping) ← truck arrival
└─ ShippingDocument (fbShippingDocument) ← supplier delivery note [1:N]
├─ ShippingItem (fbShippingItem) ← product line [1:N]
│ └─ ShippingItemPallet ← measurement event [1:N]
├─ ShippingDocumentToFiles ← uploaded PDFs [1:N]
│ └─ Files (fbFiles) [N:1]
└─ Partner (fbPartner) ← supplier [N:1]
```
### Outbound Order
```
OrderDto (Order) ← nopCommerce order
├─ OrderItemDto (OrderItem) ← line item [1:N]
│ ├─ OrderItemPallet (fbOrderItemPallet) ← measurement record [1:N]
│ └─ ProductDto (Product) [N:1]
├─ Customer [N:1]
└─ GenericAttributeDto ← custom attributes [1:N]
```
### Inventory (StockTaking)
```
StockTaking (fbStockTaking) ← inventory session
└─ StockTakingItem (fbStockTakingItem) ← product line [1:N]
├─ StockTakingItemPallet ← measurement record [1:N]
└─ ProductDto (Product) [N:1]
```
## FullProcessModel
Container for bulk data sync between server and FruitBankHybridApp via SignalR:
| Property | Type | Purpose |
|---|---|---|
| `Orders` | `List<OrderDto>` | All active orders with full graph |
| `Shippings` | `List<Shipping>` | All active shipments with full graph |
| `StockTakings` | `List<StockTaking>` | All active inventory sessions |
## Note on "Pallet" Naming
The term "Pallet" in `OrderItemPallet`, `ShippingItemPallet`, and `StockTakingItemPallet` is a legacy naming convention. These are **general measurement records** that are always created for every item, regardless of whether goods arrive on a physical pallet. For non-measurable products, weight fields are 0.0 and only `TrayQuantity` is tracked.

# Measurement Workflows
> Part of `Nop.Plugin.Misc.FruitBankPlugin`. See `README.md` for project overview.
> For entity model see `docs/DOMAIN_MODEL.md`.
> For SignalR endpoints see `docs/SIGNALR_ENDPOINTS.md`.
> For core measurement system rules and common domain traps, see: `../../../../../FruitBankHybridApp/FruitBank.Common/docs/GLOSSARY.md`
Three parallel measurement workflows share the same weight formula and `MeasuringStatus` lifecycle.
## MeasuringStatus Lifecycle
```
NotStarted (0) → Started (10) → Finnished (20) → Audited (30)
[no record] [record created] [IsMeasured=true] [RevisorId > 0]
```
- **NotStarted**: No pallet record exists yet
- **Started**: Pallet record created (Id > 0) but `IsMeasured = false`
- **Finnished**: `IsMeasured = true` — weights recorded
- **Audited**: `RevisorId > 0` — quality auditor confirmed (OrderItemPallet only)
## IsMeasurable Flag
`ProductDto.IsMeasurable` is the master toggle (stored as GenericAttribute). When `false`:
- Weight validation is bypassed
- One pallet record is still created with `GrossWeight = 0.0`
- Only `TrayQuantity` is recorded (for tare-weight calculations)
- Product is not included in average weight checks
## Workflow 1: Inbound Shipping
Supplier truck arrives at the warehouse. Goods are weighed and compared to the delivery document.
```
Shipping (truck)
→ ShippingDocument (supplier delivery note)
→ ShippingItem (product line)
→ ShippingItemPallet (individual measurement)
```
### Flow
1. **Create Shipping** — truck registration (LicencePlate, ShippingDate, CargoCompany)
2. **Add ShippingDocument** — link to Partner (supplier), upload PDF delivery note
3. **Add ShippingItem** — product line from document. `IsMeasurable` copied from `ProductDto.IsMeasurable`
4. **Weigh pallets**`FruitBankDataController.AddOrUpdateMeasuredShippingItemPallet()`
- Each pallet: GrossWeight, PalletWeight, TareWeight, TrayQuantity
- NetWeight computed: `GrossWeight - PalletWeight - (TrayQuantity * TareWeight)`
5. **Cascade update** — after each pallet measurement:
- `ShippingItem`: MeasuredGrossWeight, MeasuredNetWeight, MeasuredQuantity recalculated from pallets
- `ShippingDocument.IsAllMeasured` = all items measured
- `Shipping.IsAllMeasured` = all documents measured
- Product `AverageWeight` updated from measured data
### Event Cascade (FruitBankEventConsumer)
```
ShippingItemPallet deleted → ShippingItem measuring values refreshed
ShippingItem inserted/updated → ShippingDocument.IsAllMeasured rechecked
ShippingDocument inserted/updated → Shipping.IsAllMeasured rechecked
Shipping deleted → cascade delete ShippingDocuments
ShippingDocument deleted → cascade delete ShippingItems
ShippingItem deleted → cascade delete ShippingItemPallets
```
### ShippingItem: Declared vs Measured
| Declared (from document) | Measured (warehouse) | Discrepancy tracked |
|---|---|---|
| `QuantityOnDocument` | `MeasuredQuantity` | Yes |
| `GrossWeightOnDocument` | `MeasuredGrossWeight` | Yes |
| `NetWeightOnDocument` | `MeasuredNetWeight` | Yes |
## Workflow 2: Outbound Order
Customer order is prepared. Items are weighed before dispatch.
```
OrderDto (order)
→ OrderItemDto (line item)
→ OrderItemPallet (measurement record)
```
### Flow
1. **Start Measuring**`CustomOrderSignalREndpoint.StartMeasuring(orderId, userId)`
- Sets `MeasurementOwnerId` via GenericAttribute
- Order status set to Processing, Payment to Pending
- Broadcasts `SendOrderChanged`
2. **Weigh pallets**`CustomOrderSignalREndpoint.AddOrUpdateMeasuredOrderItemPallet()`
- Same weight formula as shipping
- Triggers price recalculation after each pallet
- Broadcasts `SendOrderItemPalletChanged`
3. **Complete order**`CustomOrderSignalREndpoint.SetOrderStatusToComplete(orderId, revisorId)`
- Validates: all order items must have pallets
- Recalculates final prices via `CustomPriceCalculationService`
- Updates product stock quantities and weights
- Sets `RevisorId` on each OrderItemPallet → MeasuringStatus becomes Audited
- Order status → Complete
- Publishes `OrderPaidEvent` for nopCommerce integration
### Average Weight Validation
After measuring, `OrderItemDto.AverageWeightIsValid` checks:
```
deviation = |ProductDto.AverageWeight - OrderItemDto.AverageWeight|
percentage = (deviation / ProductDto.AverageWeight) * 100
valid = percentage < ProductDto.AverageWeightTreshold
```
`OrderDto.IsAllOrderItemAvgWeightValid` = all items pass this check.
### PendingMeasurementCheckoutFilter
ASP.NET Core action filter on the Checkout `ConfirmOrder` action.
| Step | Action |
|---|---|
| Intercept | `ConfirmOrder` POST in CheckoutController |
| Check | `OrderMeasurementService.IsPendingMeasurementAsync()` |
| If pending | Set OrderStatus=Processing, PaymentStatus=Pending, redirect to PendingMeasurementWarning |
| If not pending | Allow normal checkout flow |
## Workflow 3: StockTaking
Inventory session compares logical stock with physical count.
```
StockTaking (session)
→ StockTakingItem (product line)
→ StockTakingItemPallet (measurement record)
```
### Flow
1. **Create session**`StockSignalREndpointServer.AddStockTaking()`
- Auto-populates `StockTakingItem` for each product
- Captures `OriginalStockQuantity` (current stock) and `InProcessOrdersQuantity` (reserved in pending orders)
- `TotalOriginalQuantity = OriginalStockQuantity + InProcessOrdersQuantity`
2. **Weigh items**`StockSignalREndpointServer.AddOrUpdateMeasuredStockTakingItemPallet()`
- Same weight formula
- Refreshes `MeasuredStockQuantity` and `MeasuredNetWeight` from pallets
3. **Close session**`StockSignalREndpointServer.CloseStockTaking()`
- Validates: all items must be measured
- For each item: `QuantityDiff = MeasuredStockQuantity - TotalOriginalQuantity`
- Updates `Product.StockQuantity` with the diff
- Updates `Product.NetWeight` with measured weight
- Creates stock quantity history entries
- Marks session as closed (`IsClosed = true`)
## CustomPriceCalculationService
Extends nopCommerce's `PriceCalculationService`. Overrides order item pricing based on measurement data.
| Scenario | Price calculation |
|---|---|
| Measurable product | `FinalPrice = NetWeight * UnitPriceExclTax` (weight-based) |
| Non-measurable product | `FinalPrice = Quantity * UnitPriceExclTax` (standard quantity-based) |
**Methods:**
| Method | Purpose |
|---|---|
| `CalculateOrderItemFinalPrice(OrderItemDto)` | Single item price calculation |
| `CheckAndUpdateOrderItemFinalPricesAsync(int orderId)` | Recalculates all items in an order |
| `CheckAndUpdateOrderTotalPrice(int orderId)` | Updates order total from item sum |
## Stock Update Flow
When an order is completed or a stocktaking session closes, `FruitBankDbContext.UpdateStockQuantityAndWeightAsync()`:
1. Updates `Product.StockQuantity` (add/subtract delta)
2. Updates `Product.NetWeight` via GenericAttribute
3. Creates `StockQuantityHistory` entry with extension record for audit trail

| ClientTimeoutInterval | 30 seconds |
| MaximumReceiveMessageSize | 30 MB |
| EnableDetailedErrors | true |
Hubs registered: `DevAdminSignalRHub`, `LoggerSignalRHub` (from AyCode.Core.Server).
## FruitBankHub
`Services/FruitBankHub.cs` — Minimal hub inheriting `Hub`.
| Method | Purpose |
|---|---|
| `SendMessage(string user, string message)` | Broadcast message to all connected clients |
## CustomOrderSignalREndpoint
`Areas/Admin/Controllers/CustomOrderSignalREndpoint.cs` — Order management via SignalR. Implements `ICustomOrderSignalREndpointServer`.
### Query Methods
| Method | Parameters | Returns | Broadcast Tag |
|---|---|---|---|
| `GetAllOrderDtos()` | — | Orders from last 15 days with relations | — |
| `GetOrderDtoById` | orderId | Single order with relations | — |
| `GetPendingOrderDtos()` | — | Pending status orders | — |
