# Code Generation Summary — Unit 1: Backend Dual-Instance Hosting

## Created

- `src/SlpModularCms.Core/Hosting/ModuleOrchestrator.cs`
- `src/SlpModularCms.Core/Hosting/ServiceCollectionExtensions.cs`
- `src/SlpModularCms.Core/Hosting/ApiPrefixConvention.cs`
- `src/SlpModularCms.Api.Slave/SlpModularCms.Api.Slave.csproj`
- `src/SlpModularCms.Api.Slave/Program.cs`
- `src/SlpModularCms.Api.Slave/appsettings.json`
- `src/SlpModularCms.Api.Slave/appsettings.Development.json`
- `src/SlpModularCms.Api.Slave/appsettings.local.json.example`
- `src/SlpModularCms.Api.Slave/Properties/launchSettings.json`
- `src/SlpModularCms.Core.Tests/Hosting/ApiPrefixConventionTests.cs` (relocated from `Modules.Identity.Tests`)
- `src/SlpModularCms.Core.Tests/Hosting/ModuleOrchestratorTests.cs` (relocated from `Modules.Identity.Tests`)

## Modified

- `src/SlpModularCms.Core/SlpModularCms.Core.csproj` — added `Asp.Versioning.Mvc` and `Microsoft.AspNetCore.OpenApi` package references
- `src/SlpModularCms.Api/Program.cs` — `using` statements updated to `SlpModularCms.Core.Hosting` (no logic change)
- `src/SlpModularCms.Modules.Identity.Tests/SlpModularCms.Modules.Identity.Tests.csproj` — removed `ProjectReference` to `SlpModularCms.Api` (no longer needed; the only tests using it were relocated to `Core.Tests`)
- `SlpModularCms.sln` — added `SlpModularCms.Api.Slave` project entry, build configurations, and solution-folder nesting under `src`

## Deleted

- `src/SlpModularCms.Api/Infrastructure/ModuleOrchestrator.cs` (moved to Core)
- `src/SlpModularCms.Api/Extensions/ServiceCollectionExtensions.cs` (moved to Core)
- `src/SlpModularCms.Api/Infrastructure/ApiPrefixConvention.cs` (moved to Core)
- `src/SlpModularCms.Modules.Identity.Tests/Infrastructure/ModuleOrchestratorTests.cs` (relocated to `Core.Tests/Hosting/`)
- `src/SlpModularCms.Modules.Identity.Tests/Infrastructure/ApiPrefixConventionTests.cs` (relocated to `Core.Tests/Hosting/`)

## Notes / Deviations from Plan

- Discovered during generation that `SlpModularCms.Modules.Identity.Tests` referenced `SlpModularCms.Api` solely to test `ModuleOrchestrator`/`ApiPrefixConvention` — an existing layering quirk, not something this feature introduced. Since those classes now live in `Core`, their tests were relocated to `Core.Tests/Hosting/` (which already references `Core` and already has all needed test packages: FluentAssertions, NSubstitute, xunit). This removed the odd cross-project test dependency as a side effect.
- `ServiceCollectionExtensions.cs` needed explicit `using Microsoft.Extensions.Configuration;`, `using Microsoft.Extensions.DependencyInjection;`, `using Microsoft.AspNetCore.Builder;`, and `using Microsoft.AspNetCore.Http;` after the move — `SlpModularCms.Api` is a `Microsoft.NET.Sdk.Web` project (implicit ASP.NET Core usings), while `SlpModularCms.Core` is a plain `Microsoft.NET.Sdk` project, so these weren't implicitly available.
- Left `Asp.Versioning.Mvc` and `Microsoft.AspNetCore.OpenApi` package references in place on `SlpModularCms.Api.csproj` even though they're now also referenced transitively via `Core` — removing them was optional per the plan and the build succeeds either way; left as-is to minimize unrelated diff.

## Verification Performed

- `dotnet build SlpModularCms.sln` — succeeds, no errors.
- `dotnet test SlpModularCms.sln` — all 4 existing test projects pass unchanged: `Core.Tests` (54), `Modules.Availability.Tests` (60), `Modules.Identity.Tests` (37), `Modules.Master.Tests` (42).
- Manually ran `dotnet run --launch-profile https` in both `SlpModularCms.Api` and `SlpModularCms.Api.Slave`:
  - **Master** (`SlpModularCms.Api`): discovers and loads all 3 modules — Availability, Identity, Master.
  - **Slave** (`SlpModularCms.Api.Slave`): discovers and loads exactly 2 modules — Availability, Identity. **Master is correctly excluded.**
- Full end-to-end run (requiring a real local SQL Server/localdb instance and manual "Add CMS Instance" registration) is deferred to Build and Test / Unit 2, per the plan.
