+# GoodWood App Notes
+
+## Architecture
+- Blazor Server (.NET 9), Clean Architecture: Domain → Application → Infrastructure → Web
+- Fluxor (Redux): Store/{Feature}State/{Actions,Reducers,Effects,State}.cs pattern
+- AutoMapper profiles in Application/Mapping/
+- EF migrations: `dotnet ef migrations add [Name] --project src/GoodWood.Infrastructure --startup-project src/GoodWood.Web --context AppDbContext --output-dir Data/Migrations`
+- Dual DbContext: AppDbContext (app schema), AppIdentityDbContext (auth schema)
+
+## Code-behind pattern
+- Partial classes: Component.razor + Component.razor.cs
+- [Inject] needs `using Microsoft.AspNetCore.Components;` in .cs files (not auto-imported unlike .razor)
+
+## SEPA Export (added 2026-02-08)
+- pain.008.003.02 XML generated by SepaXmlBuilder (System.Xml, no external lib)
+- Download via JS: `window.downloadFile` in wwwroot/js/fileDownload.js
+- SepaExport entity links CashBookEntries via nullable FK SepaExportId
+- PaymentStatus enum on CashBookEntry: Open/DirectDebitCollected/Paid
+- Person gets: Iban, Bic, SepaMandateReference, SepaMandateDate
+- Club gets: BankIban, BankBic, SepaCreditorId

+# ISMS-DB Project Memory
+
+## Skill Triggers
+- "aktualisiere unser ISMS", "ISMS aktualisieren", "ISMS updaten" → ALWAYS invoke Skill `isms-update`
+- This skill runs: Fetch-Data.ps1 → edit JSON → Upload-Data.ps1
+- NEVER edit tenant data (Data/default/*.json) without running fetch first
+- NEVER skip upload after editing
+
+## Auth Stack
+- Microsoft.Identity.Web 3.x (resolved 3.14.1)
+- Use `AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme).AddMicrosoftIdentityWebApp(...)` — NOT `services.AddMicrosoftIdentityWebApp(...)` (IServiceCollection overload removed in 3.x)
+- `using Microsoft.Identity.Web.UI;` required in Program.cs for `AddMicrosoftIdentityUI()`
+- Use `PostConfigure<OpenIdConnectOptions>` to hook `OnTokenValidated` without clobbering MSIW's own handler
+
+## SecurePageModel Pattern
+- Inherits `PageModel`, uses `override` on `OnPageHandlerSelectionAsync` / `OnPageHandlerExecutionAsync`
+- Do NOT declare `IAsyncPageFilter` explicitly — `PageModel` already has virtual methods
+- Resolves `IUserService` + `TenantService` via `ctx.HttpContext.RequestServices`
+
+## Audit Result Writing
+- NEVER delegate JSON creation to a Task subagent — too slow (33 calls, 17 min)
+- Build the JSON object in main context, then pipe to `append-audit-result.py`:
+  `python3 append-audit-result.py src/IsmsApp/Data/default/ <<'JSONEOF' ... JSONEOF`
+- Script validates: .lock, control exists, Id unique, Iteration unique
+- For the JSON heredoc: use python3 inline to generate UUIDs + timestamps, then echo
+
+## Razor Gotcha
+- `RZ1031`: cannot put free-standing `@(expr)` in `<option>` attribute area
+- Fix: use `@if (cond) { <option selected> } else { <option> }` pattern instead

+# KbsV3 Memory
+
+## Architecture Guide
+- See [kbsv3-architecture.md](kbsv3-architecture.md) for: Job system, SAP RFC calls, gRPC communication, DB read/write patterns
+
+## Plotly.Blazor (v7.0.0)
+- `ModeFlag` namespace: `Plotly.Blazor.Traces.ScatterLib`
+- `XAxis.Type` needs `Plotly.Blazor.LayoutLib.XAxisLib.TypeEnum.Date` (not string)
+- `Title` is ambiguous between `LayoutLib` and `LayoutLib.XAxisLib` — use fully qualified
+- Events (relayout) not implemented in library — use JS interop via `el.on('plotly_relayout', ...)`
+
+## Service Layer Pattern
+- Services use `JobDbContext` injected directly
+- Interface in `Contract/`, implementation in `Services/`
+- Register in `Program.cs` as `builder.Services.AddScoped<IFoo, Foo>()`
+
+## SAP NCo3 IRfcFunction
+- `IRfcFunction` does NOT implement `IDisposable` — `using var fnc` causes CS1674 compile error
+- NCo3 manages memory via GC; `fnc` vars in method scope are eligible for collection after method returns
+- Fix 1 from memory-optimization plan is NOT applicable via `using`; no explicit disposal mechanism available
+
+## Job Worker Patterns (IKbsJob vs ILongRunningJobService)
+- **All KnownJobs** in Kbs3SqlService use `IKbsJob` (NOT `ILongRunningJobService`)
+- `IKbsJob` runs via `LongRunningJobServiceHost` with `JobType.CallServiceHost`
+- Auto-registered as keyed service by class name (e.g. `"SyncOpexPurchaseOrdersService"`)
+- `IKnownJob.ServiceName` format: `"modulename.ClassName"` → host splits on `.` and resolves last segment
+- Do NOT add new `JobType` enum entries for `IKbsJob` workers — they all share `CallServiceHost`
+- `ILongRunningJobService` is for services like AD sync, Hydra — they have dedicated JobType enum entries
+
+## HydraArchiveData
+- Entity: HydraArchiveReloadId, AcquisitionTime, PdatrefPparamDatasupId, DecimalValue
+- Covering index: (HydraArchiveReloadId, AcquisitionTime, PdatrefPparamDatasupId)
+- SQL bucket aggregation: DATEDIFF/DATEADD pattern for time-bucket grouping
+- Raw SQL via `_dbContext.Database.SqlQueryRaw<T>(sql, params)`

+# KbsV3 Architecture Patterns
+
+## 1. Job System (IKnownJob → Worker)
+
+### Creating a new Job (full checklist)
+1. **JobType enum** → `GrpcProtos/GrpcServices/Contracts/JobType.cs` — add `[StringValue("X")] X`
+2. **IKnownJob** → `GrpcProtos/GrpcServices/KnownJobs/MyJob.cs` — metadata class
+   - `ServiceName` format: `"modulename.WorkerClassName"` (e.g. `"sqlsync.UpdateCalcPriceService"`)
+   - Module names: `helpdesk`, `sqlsync`, `ad`, `azure`, `docuware`, `sap`, `scheduler`
+3. **Worker** → `Kbs3XxxService/Services/MyWorker.cs` — implements `ILongRunningJobService`
+   - Constructor: `ProtocolLogger`, `IApiComposer`, plus custom DI
+   - `JobType` property returns `GetJobType()` (static method using `JobType.X.GetStringValue()`)
+   - `Run(JobDataRequest, CancellationToken)` → business logic
+   - `GetHeadline()` → section title
+4. **Auto-registration** — `IntegrationServiceBase.AutoInjectServices()` discovers workers automatically
+5. **No changes needed** in Program.cs of the microservice
+
+### Worker capabilities
+- `ProtocolLogger.LogHeadline/LogInfo/LogWarn/LogError` — streams to UI in real-time
+- `apiComposer` — callback to server (see section 3)
+- `request.InputData` — string input (usually username or JSON payload)
+
+### IKnownJob with Payload
+- `Payload` property returns a typed object (serialized as InputData)
+- Example: `UpdateCalculationPriceDatabase.cs` returns `UpdateCalcPriceRequest`
+
+## 2. SAP Data Access (RFC Calls)
+
+### Where RFC calls live
+- **Kbs3SapService/SapServices/** — e.g. `OrderService.cs`, `FiService.cs`, `TableService.cs`
+- Uses SAP NCo3: `RfcDestinationManager.GetDestination(systemName)` → `repos.CreateFunction("Z_FUNC")` → `fnc.Invoke(dest)`
+- `IRfcFunction` does NOT implement IDisposable
+
+### RFC call pattern
+```csharp
+var dest = RfcDestinationManager.GetDestination(request.SystemName);
+var repos = dest.Repository;
+var fnc = repos.CreateFunction("Z_RFC_NAME");
+fnc.SetValue("PARAM", value);           // importing params
+fnc.Invoke(dest);
+var itResult = fnc.GetTable("ET_TABLE"); // exporting table
+for (var i = 0; i < itResult.RowCount; i++) {
+    itResult.CurrentIndex = i;
+    var val = itResult.GetString("FIELD");
+}
+```
+
+### Extension methods (Kbs3SapService/Extensions/)
+- `DateTime.ToSapDate()` → SAP date string
+- `itResult.GetDateTimeOrNull("FIELD")` → nullable DateTime
+- `itResult.GetDecimal("FIELD")`, `GetBoolean("FIELD")`, etc.
+
+### gRPC service wrapper
+- `Kbs3SapService/GrpcServices/SapOrderService.cs` — thin proxy implementing `ISapOrderService`
+- Delegates to the actual `OrderService` (SapServices layer)
+
+## 3. gRPC Communication Between Modules
+
+### Contract interfaces
+- **Location:** `GrpcProtos/GrpcServices/Contracts/SapService/` (e.g. `ISapOrderService.cs`)
+- Attributes: `[ServiceContract]`, `[OperationContract]`
+- DTOs: `[DataContract]` + `[DataMember(Order = N)]`
+
+### DTO conventions
+- Namespace: `GrpcProtos.GrpcServices.Model` (data classes) or `Contracts/SapService/` (request/response)
+- Collections: `Type[] prop = []`
+- Nullable refs: `string?`, `DateTime?`
+- Sequential `[DataMember(Order = N)]` starting at 1
+- `BapiMessage[]` for error handling
+
+### Server → Microservice (gRPC Client)
+- **Location:** `Kbs3ServerService/GrpcClients/` (e.g. `SapOrderServiceClient.cs`)
+- Inherits `GrpcClientBase<ISapOrderService>`
+- Constructor: `(GrpcChannel, ServiceRegistry, IServiceScopeFactory)`
+- Methods: `return Client?.MethodName(request);`
+
+### Microservice → Server (IApiComposer callback)
+- **Interface:** `GrpcProtos/GrpcServices/Contracts/Server/IApiComposer.cs`
+- **Implementation:** in Kbs3ServerService (ApiComposer class)
+- Workers use `apiComposer.GetUser()`, `apiComposer.GetCalcPriceInfos()`, etc.
+- To add new callback: add method to IApiComposer → implement in server ApiComposer
+
+## 4. Database Read/Write
+
+### Server-side (EF Core)
+- **DbContext:** `Kbs3ServerService.Repository/Contexts/JobDbContext.cs` (inherits `ThreadSafeDbContext`)
+- **Entities:** `Kbs3ServerService.Repository/Entities/`
+- **Base classes:** `AuditableEntity` (manual audit) or `KbEntity` (auto SQL defaults via GETUTCDATE())
+- **Global decimal precision:** 18,4
+- **Configurations:** `IEntityTypeConfiguration<T>` via `ApplyAllConfigurations()`
+- **Service layer:** `Kbs3ServerService.Service/Services/` — inject `JobDbContext`, use EF Core CRUD
+
+### Migrations
+```bash
+dotnet ef migrations add Name --project Kbs3ServerService.Repository --startup-project Kbs3ServerService
+dotnet ef database update -- Development --project Kbs3ServerService.Repository --startup-project Kbs3ServerService
+```
+
+### Microservice-side (Raw ADO.NET) — Kbs3SqlService pattern
+- `IOptions<DatabaseOptions>` → connection strings for multiple DBs
+- `ConnectionStringKbs` = main KBS app DB
+- `ConnectionStringSapCalcData` = external SAP calc DB
+- Uses `SqlConnection` + `SqlCommand` with parameterized queries
+- Pattern: `new SqlConnection(connectionString)` → `OpenAsync()` → `ExecuteNonQueryAsync()` → `CloseAsync()`
+- Example: `UpdateCalcPriceService.cs` — fetches via `apiComposer`, writes via raw SQL
+
+### Key difference
+| Location | Technology | Use case |
+|----------|-----------|----------|
+| Kbs3ServerService | EF Core (JobDbContext) | Main app CRUD, entities, migrations |
+| Kbs3SqlService | Raw ADO.NET (SqlConnection) | Bulk sync to external/app DBs from workers |
+| Kbs3SapService | None | No direct DB access — SAP only |
+
+## 5. Service Registration
+
+### Server services
+- Interface in `Contract/`, implementation in `Services/`
+- `builder.Services.AddScoped<IFoo, Foo>()` in `Program.cs`
+
+### Microservice workers
+- Auto-discovered by `IntegrationServiceBase.AutoInjectServices()`
+- Keyed service: `services.AddKeyedScoped<ILongRunningJobService>(jobType, workerType)`
