## Initiële Setup (Bootstrapping)
Wanneer de applicatie voor de eerste keer wordt gestart met een lege database, moet er een "Owner" (eigenaar) worden aangemaakt. Dit kan via de setup endpoints.
...
### 1. Status controleren
Controleer of het systeem al geïnitialiseerd is:
- **Endpoint**: `GET /api/v1/Setup/status`
- **Response**: `{ "initialized": true/false }`
## Authenticatie & Security (Unit 0)
### 2. Eerste Owner aanmaken
Dit endpoint is alleen bruikbaar als er nog geen Owner in de database staat.
- **Endpoint**: `POST /api/v1/Setup/owner`
- **Payload**:
```json
{
"email": "admin@example.com",
"password": "JeWachtwoord123!"
}
```
De API gebruikt een beveiligde flow voor authenticatie:
- **Login**: `POST /api/v1/auth/login`. Retourneert een `accessToken` in de body en een `refreshToken` in een beveiligde `httpOnly` cookie.
- **Refresh**: `POST /api/v1/auth/refresh`. Gebruikt de `refreshToken` cookie om een nieuwe `accessToken` en `refreshToken` (rotatie) te genereren.
- **Revoke**: `POST /api/v1/auth/revoke`. Trekt het token in en wist de cookie.
### Belangrijke NFR Details:
- **CORS**: Alleen toegestane origins uit `appsettings.json → Cors:AllowedOrigins` worden geaccepteerd. De frontend moet draaien op een van deze origins.
- **Cookies**: De `refreshToken` cookie is `httpOnly`, `SameSite=Strict` en heeft het pad `/api/v1/auth`.
- **Rate Limiting**: Login endpoints hebben rate limiting (Fixed window 5/min, Sliding window 20/min).
- **Error Handling**: Foutmeldingen volgen de RFC 9457 `ProblemDetails` standaard.

# Code Generation Plan — Unit 0: Backend Prerequisites
This plan defines all concrete steps to implement Unit 0 (backend prerequisites) safely in the brownfield .NET solution. Follow the numbered steps in order and check them off during execution.
## Unit Context
- Unit: Unit 0 — Backend Prerequisites
- Type: .NET backend changes (API + Core + Module Identity)
- Stories (traceability):
- US-02 (partial) — Auth: secure refresh-token via httpOnly cookie
- US-06 (partial) — Session lifecycle: refresh & revoke
- US-07 (partial) — Error handling & API consistency
- Dependencies: None (prerequisite unit for all frontend integration)
- Related NFRs: NFR-U0-01..07 (security cookie, CORS, rate limiting, reliability, ProblemDetails, maintainability, tests)
## Code Locations (brownfield)
- Application Code:
- src/SlpModularCms.Api/Program.cs
- src/SlpModularCms.Api/Extensions/ServiceCollectionExtensions.cs
- src/SlpModularCms.Modules.Identity/Controllers/AuthController.cs
- src/SlpModularCms.Core/Exceptions/GlobalExceptionHandler.cs
- src/SlpModularCms.Core/Exceptions/ApiErrorResponse.cs (to be removed/replaced)
- src/SlpModularCms.Core/Identity/Models/TokenResponse.cs
- src/SlpModularCms.Core/Identity/Models/IdentityRequests.cs (contains RefreshTokenRequest)
- src/SlpModularCms.Core/Identity/Services/IAuthService.cs
- src/SlpModularCms.Core/Identity/Services/AuthService.cs
- Configuration:
- src/SlpModularCms.Api/appsettings.json
- src/SlpModularCms.Api/appsettings.Development.json
- Tests:
- src/SlpModularCms.Core.Tests/Identity/* (extend where feasible)
- NEW: src/SlpModularCms.Modules.Identity.Tests/ (controller tests) [optional, recommended]
## PART 1 — Planning Checklist
- [x] Read all Unit 0 design artifacts (business-rules.md, nfr-requirements.md, nfr-design/*)
- [x] Validate repository state and file presence against paths above
- [x] Confirm appsettings three-file pattern (dotnet-appsettings skill) and add missing sections
## PART 2 — Generation Steps (execute in order)
### Step 1 — API Routing & CORS
- [x] Update route on AuthController to `[Route("api/v1/auth")]` (currently `[Route("[controller]")]`)
- [x] Add `AddCmsCors()` in ServiceCollectionExtensions to read `Cors:AllowedOrigins` and configure explicit allowlist + `AllowCredentials()`
- [x] Register CORS BEFORE `UseAuthentication`/`UseAuthorization` in Program.cs pipeline
- [x] Add `Cors` section to appsettings.json and appsettings.Development.json per logical-components.md
### Step 2 — Rate Limiting (Global Middleware)
- [x] Add `AddCmsRateLimiting()` to register Fixed window (login: 5/min) and Sliding window (refresh: 20/min)
- [x] Register `UseRateLimiter()` in Program.cs before CORS (per design ordering)
- [x] Ensure 429 responses include standard headers (Retry-After) where applicable
### Step 3 — Refresh Token in httpOnly Cookie
- [x] Modify `AuthController.Login` to set `refreshToken` cookie (`HttpOnly`, `Secure=request.IsHttps` in prod, `SameSite=Strict`, Path=/api/v1/auth)
- [x] Modify `AuthController.Refresh` to read refresh token from `Request.Cookies["refreshToken"]` (remove body model)
- [x] Modify `AuthController.Revoke` to clear the cookie using same Path and expire to Epoch
### Step 4 — Remove Request Body Model for Refresh
- [x] Delete `RefreshTokenRequest` from `IdentityRequests.cs`
- [x] Update method signatures & usages accordingly
### Step 5 — Service Contract Adjustments (AuthService/IAuthService)
- [x] Change refresh flow contract to accept ONLY the refresh token (no access token in body)
- [x] Implement repository lookup by refresh token and user, with rotation semantics intact
- [x] Ensure reuse-detection logic (mark used, revoke all on reuse) remains functional
### Step 6 — Response Model & Payload Alignment
- [x] Update `TokenResponse` to remove `RefreshToken` from the response body
- [x] Extend response body to include: `accessToken`, `expiresAt`, and `user` object: `{ id, email, name, role, isActive }`
- [x] Compute `name` as `DisplayName ?? Email` (see BR-U0-07)
- [x] Ensure controllers only return allowed fields; NEVER return the refresh token
### Step 7 — Revoke Endpoint Authorization Policy
- [x] Implement per BR-U0-05: remove `[Authorize]` from `POST /api/v1/auth/revoke` to allow idempotent logout even if access token expired
### Step 8 — ProblemDetails Migration (RFC 9457)
- [x] Replace custom `ApiErrorResponse` with standardized `ProblemDetails` in `GlobalExceptionHandler`
- [x] Map known exceptions to appropriate status codes (Unauthorized, 429, etc.)
- [x] Remove/retire `ApiErrorResponse` usages
### Step 9 — Configuration (dotnet-appsettings)
- [x] Add/verify `Cors` and `RateLimiting` sections in `appsettings.json` and `appsettings.Development.json`
- [x] Do NOT store secrets; follow three-file pattern; add README notes for `appsettings.local.json` overrides
### Step 10 — Tests
- [x] Update/extend unit tests to cover:
- Cookie set on successful login/refresh
- Cookie cleared on revoke
- 401 when cookie missing on refresh
- Rate limit behavior (mock/stub)
- [x] Optionally add `SlpModularCms.Modules.Identity.Tests` for controller-level tests; otherwise, add minimal WebApplicationFactory-based tests in an existing test project
### Step 11 — Documentation & README
- [x] Update backend README with local dev instructions (CORS origin, HTTPS dev certs, cookie behavior)
- [x] Update cross-feature docs if affected (e.g., slp-modular-cms-api endpoints, auth flow)
### Step 12 — Build & Smoke Verification
- [x] Build solution
- [x] Manual smoke test of auth endpoints: login → cookie present; refresh → cookie rotates; revoke → cookie cleared; CORS preflight succeeds
## Story Traceability Matrix
- US-02 (partial): Steps 36
- US-06 (partial): Steps 37, 12
- US-07 (partial): Steps 812
## Definition of Done (Unit 0)
- [ ] No refresh token in any response body
- [ ] Refresh token exclusively in httpOnly cookie
- [ ] CORS allowlist enforced and credentials enabled
- [ ] Global rate limiting active with configured windows
- [ ] ProblemDetails standardized for all auth-related errors

# Logical Components — Unit 0: Backend Prerequisites
The following logical components and configuration structures are defined to support the NFR implementation.
## 1. Middleware Ordering (Pipeline Design)
The order of middleware registration is critical for security and performance. The pipeline is configured in `Program.cs`.
```mermaid
graph TD
Start((Start)) --> Exc[GlobalExceptionHandler]
Exc --> RL[Rate Limiter]
RL --> CORS[CORS Middleware]
CORS --> Auth[Authentication]
Auth --> Map[Endpoint Mapping]
Map --> End((End))

classDef core fill:#9ae6b4,stroke:#22543d,stroke-width:2px,color:#22543d;
class Start,End,Map infra;
class Exc,RL,CORS,Auth security;
```
Text alternative: Sequence of middleware in the ASP.NET Core pipeline (colored nodes indicate role).
## 2. Configuration Structure (appsettings.json)
Following the `dotnet-appsettings` skill pattern, the configuration for NFRs is centralized.
### CORS Configuration
```json
"Cors": {
"AllowedOrigins": [
"https://localhost:5173"
]
}
```
### Rate Limiting Configuration
```json
"RateLimiting": {
"Login": {
"PermitLimit": 5,
"WindowSeconds": 60
},
"Refresh": {
"PermitLimit": 20,
"WindowSeconds": 60
}
}
```
## 3. Extension Methods
To keep `Program.cs` clean, logical components are encapsulated in `ServiceCollectionExtensions.cs`.
| Component | Responsibility |
|-----------|----------------|
| `AddCmsCors()` | Configures the CORS policy based on settings. |
| `AddCmsRateLimiting()` | Defines the Fixed and Sliding window policies for auth. |
| `AddCmsExceptionHandling()` | Registers the `GlobalExceptionHandler` and ProblemDetails. |
## 4. ProblemDetails Integration
The `GlobalExceptionHandler` will be modified to fully replace the custom `ApiErrorResponse` with standard `ProblemDetails` as the return type. No backward compatibility for the old error format is required.

# NFR Design Patterns — Unit 0: Backend Prerequisites
Non-functional requirements are addressed using the following design patterns and implementation strategies.
## Resilience & Protection Patterns
### 1. Global Rate Limiting Pipeline
To protect the authentication endpoints from brute-force and DoS attacks, a global rate limiting pipeline is implemented using the built-in ASP.NET Core `Microsoft.AspNetCore.RateLimiting` middleware.
- **Fixed Window Pattern (Login)**:
- Scoped to `POST /api/v1/auth/login`.
- Limit: 5 requests per 1 minute.
- Partitioned by Client IP Address.
- **Sliding Window Pattern (Refresh)**:
- Scoped to `POST /api/v1/auth/refresh`.
- Limit: 20 requests per 1 minute.
- Partitioned by Client IP Address.
```mermaid
graph TD
Client[Client Request] --> RL[Rate Limiter Middleware]
RL -- Limit Exceeded --> 429[429 Too Many Requests]
RL -- Within Limit --> Pipeline[Authentication Pipeline]
classDef client fill:#fef3c7,stroke:#92400e,stroke-width:2px,color:#92400e;
classDef security fill:#feb2b2,stroke:#742a2a,stroke-width:2px,color:#742a2a;
classDef success fill:#c6f6d5,stroke:#22543d,stroke-width:2px,color:#22543d;
class Client client;
class RL,429 security;
class Pipeline success;
```
Text alternative: Flow showing Rate Limiter Middleware intercepting requests and either returning 429 or passing to the pipeline (colored nodes indicate role).
## Security Patterns
### 2. Cross-Origin Resource Sharing (CORS) Policy
CORS is configured via a strongly-typed `ServiceCollectionExtensions` method to ensure consistent application of security rules.
- **Pattern**: Explicit Origin Allowlist.
- **Logic**: Origin is validated against `Cors:AllowedOrigins` in `appsettings.json`.
- **Requirement**: `AllowCredentials()` is mandatory to support the `httpOnly` Refresh Token cookie cross-origin.
### 3. Secure Cookie Pattern (Refresh Token)
The Refresh Token is stored using a multi-layered security approach:
- **HttpOnly**: Prevents access via JavaScript (XSS protection).
- **Secure**: Ensures the cookie is only transmitted over HTTPS (In production).
- **SameSite=Strict**: Prevents the browser from sending the cookie with cross-site requests (CSRF protection).
- **Scoped Path**: Path is restricted to `/api/v1/auth` to minimize exposure.
## Performance & Reliability Patterns
### 4. Standardized RFC 9457 Error Handling
Existing `GlobalExceptionHandler` is extended to return `ProblemDetails` conform RFC 9457. This ensures client-side libraries can predictably parse error responses.
- **Mapping**: Specific exceptions (e.g. `UnauthorizedAccessException`, `RateLimitRejectedException`) are mapped to their corresponding HTTP status codes.
- **Safety**: Stack traces are only included in `Development` environment.
```mermaid
