# RpgRoller

Fresh full-stack starter scaffold:

- `RpgRoller/`: ASP.NET Core backend + Blazor frontend host (`Components` + `wwwroot`)
- `RpgRoller.Tests/`: xUnit integration-heavy test project
- `RpgRoller.sln`: solution used by local CI script

Test layout:

- `RpgRoller.Tests/Api/`: API integration tests grouped by feature concern
- `RpgRoller.Tests/Services/`: service-level tests grouped by domain concern
- `RpgRoller.Tests/Support/`: shared test harnesses/builders/helpers

## Code Organization

Backend:

- `RpgRoller/Program.cs`: thin app bootstrap only
- `RpgRoller/Hosting/`: service registration + startup initialization
- `RpgRoller/Api/`: endpoint mapping modules and auth/session filter helpers
- `RpgRoller/Services/`: game workflows with explicit method parameters (no API DTO dependencies)

Frontend:

- `RpgRoller/Components/`: Blazor root app, routes, layout and page components
- `RpgRoller/Components/Pages/Home.razor`: minimal gateway page (loading/auth/workspace switch)
- `RpgRoller/Components/Pages/Home.razor.cs`: single `Home` code-behind with only gateway/session-view orchestration
- `RpgRoller/Components/Pages/Workspace.razor`: authenticated workspace UI and workspace-specific state/logic
- `RpgRoller/Components/**/*.razor.cs`: component code-behind classes (state, handlers, parameters, injected dependencies); `.razor` files remain markup-focused
- `RpgRoller/Components/Pages/Home.Models.cs`: reusable `FormState<TModel>` + page form models
- `RpgRoller/Components/Pages/HomeControls/`: auth, campaign management, play-screen, and modal controls extracted from `Home.razor`
- Form ownership model: controls own transient form/error state and execute their concern-specific API mutations directly
- Skill create/edit workflow ownership: `CharacterPanel` (characters own skills in UI and behavior)
- `RpgRoller/Components/RpgRollerApiClient.cs`: shared browser API client used by `Home`, `Workspace`, and leaf controls
- `RpgRoller/wwwroot/js/rpgroller-api.js`: browser-side API + SSE + session storage interop for Blazor
- `RpgRoller/wwwroot/styles.css`: responsive UX styling and theme tokens

Backend state persistence:

- EF Core with SQLite (`Microsoft.EntityFrameworkCore.Sqlite`)
- Development DB: `RpgRoller/App_Data/rpgroller.development.db`
- Default DB: `RpgRoller/App_Data/rpgroller.db`
- Database schema is created/upgraded automatically on startup via EF Core migrations (`Database.Migrate`)
- Runtime state is loaded once at startup into memory and written back to SQLite on successful state changes

Gameplay capabilities now include:

- Instant skill filtering in the character panel (filters live while typing and hides non-matching skills/groups)
- Skill groups per character with skill prototypes (create/edit/delete groups, assign/reassign skills, and prefill new skill forms from group defaults)
- Skill and skill-group deletion flows
- GM-driven character owner transfer within campaign management flows
- Character owner selection in edit modal backed by existing-username dropdown data
- Role-aware authorization with admin role support (including admin user/role management)
- Campaign deletion by campaign owner or admin (unlinks characters from the campaign and clears campaign log entries)
- Campaign management owner labels use account display names (no GUID fallback rendering)
- Character edit flow supports unlinking from campaigns (owner/GM/admin) and assigning to any existing campaign via expanded campaign options
- Campaign management supports character deletion by character owner or admin

## Prerequisites

- .NET SDK 10.0+
- PowerShell 7+
- Run `dotnet tool restore` once to enable the repo-local `dotnet-ef` command.

## Local Development

1. Run the local CI parity script:
   ```powershell
   pwsh ./scripts/ci-local.ps1
   ```
2. Start the backend:
   ```powershell
   dotnet run --project RpgRoller/RpgRoller.csproj
   ```
3. Open `http://localhost:5000` (or the port shown in the console).

VS Code F5 debug profiles are available in `.vscode/launch.json`:

- `RpgRoller: Server`
- `RpgRoller: Server + Edge (F5)`
- `RpgRoller: Server + Firefox (F5)`

To use a custom SQLite database path, set `ConnectionStrings__RpgRoller`.
To run under a subfolder (for example `/rpgroller`), set `PathBase` (for example `PathBase=/rpgroller`).

For migration authoring, use the local tool command form:

```powershell
dotnet dotnet-ef migrations add <MigrationName> --project RpgRoller/RpgRoller.csproj --startup-project RpgRoller/RpgRoller.csproj
```

## Frontend Runtime

- Runtime frontend is Blazor Server with interactive components.
- Browser interop is in `RpgRoller/wwwroot/js/rpgroller-api.js`.
- OpenAPI contract source remains at `openapi/RpgRoller.json`.

## Test and Coverage

- Tests:
  ```powershell
  dotnet test RpgRoller.Tests/RpgRoller.Tests.csproj --collect:"XPlat Code Coverage" --settings RpgRoller.Tests/coverlet.runsettings
  ```
- Coverage gate:
  ```powershell
  pwsh ./scripts/check-coverage.ps1 -MinLineRate 0.90 -MinBranchRate 0.70
  ```
- Coverage collector scope:
  - `RpgRoller.Tests/coverlet.runsettings` now measures the full backend assembly (`RpgRoller`), not only service namespace files.
