+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Overview
+
+Remote Provisioning Service Mock is a mock implementation of the PEX Remote Token Provisioning API. It allows testers and developers to configure custom responses for token provisioning endpoints, simulate various scenarios (success, errors, delays), and audit all API requests for verification.
+
+**Target Framework:** .NET 8.0
+**Storage:** Azure Table Storage
+**Purpose:** Testing and integration support for mobile wallet provisioning flows
+
+## Build and Development Commands
+
+```bash
+# Restore dependencies
+dotnet restore
+
+# Build the solution
+dotnet build
+
+# Build for release
+dotnet build -c Release
+
+# Run the service locally
+dotnet run --project RemoteProvisioningServiceMock/RemoteProvisioningServiceMock.csproj
+
+# Run tests
+dotnet test
+```
+
+### Local Development
+
+The service uses Azure Storage Emulator by default (`UseDevelopmentStorage=true` in appsettings.json). Start the Azure Storage Emulator or Azurite before running.

+## API Endpoints
+
+### Token Provisioning (`/token`)
+
+| Method | Endpoint | Description |
+|--------|----------|-------------|
+| POST | `/token/provisioning` | Get decision for step-up authentication flow |
+| POST | `/token/otp-code` | Send OTP passcode for step-up flow |
+| POST | `/token/callback` | Receive callbacks about token creation |
+
+All `/token/provisioning` and `/token/otp-code` requests validate the `Authorization` header (Basic auth with shared secret).
+
+### Settings Configuration (`/business/{businessId}/cardholder/{cardholderId}/settings`)
+
+| Method | Description |
+|--------|-------------|
+| GET | Retrieve response settings for a cardholder |
+| PUT | Configure mock response behavior |
+
+**Configurable Settings:**
+- `SharedSecret` - Expected Basic auth secret
+- `StatusCode` - HTTP status code to return (200, 400, 401, 403, 404, 500)
+- `TimeoutMls` - Response delay in milliseconds
+- `Contacts` - Contact items for step-up flow responses
+
+### Audit Logs (`/audit`)
+
+| Method | Endpoint | Description |
+|--------|----------|-------------|
+| GET | `/audit/provisioning?cardholderId=X&from=Y&search=Z` | Query provisioning requests |
+| GET | `/audit/otp-code?cardholderId=X&from=Y&search=Z` | Query OTP requests |
+| GET | `/audit/callback?cardholderId=X&from=Y&search=Z` | Query callbacks |
+
+## Architecture Patterns
+
+### Storage Layer
+
+Uses Azure Table Storage with the repository pattern:
+
+- **ResponseSettingsStorage** - Configuration storage (PartitionKey: BusinessId, RowKey: CardholderId)
+- **TokenProvisioningStorage** - Provisioning audit log
+- **OtpCodeStorage** - OTP audit log
+- **CallbackStorage** - Callback audit log
+
+All storage classes extend `AzureTableStorageAbstract` which provides:
+- Retry policy (LinearRetry, 500ms delay, 3 attempts)
+- Pagination via continuation tokens
+- DateTime validation for Azure Table limits
+
+### Dependency Injection
+
+Storage providers registered as singletons in `Startup.cs`:
+
+```csharp
+services.AddSingleton<ResponseSettingsStorage>();
+services.AddSingleton<TokenProvisioningStorage>();
+services.AddSingleton<OtpCodeStorage>();
+services.AddSingleton<CallbackStorage>();
+```
+
+### JSON Serialization
+
+Uses Newtonsoft.Json for entity serialization. PascalCase property naming configured in Startup.cs for API responses.
+
+## Testing Scenarios
+
+Configure mock responses via the Settings API to test:
+
+1. **Success flows** - StatusCode: 200 with valid Contacts
+2. **Authentication failures** - StatusCode: 401 (invalid secret)
+3. **Authorization failures** - StatusCode: 403
+4. **Not found** - StatusCode: 404
+5. **Server errors** - StatusCode: 500
+6. **Timeout simulation** - Set TimeoutMls to desired delay
+
+## CI/CD Pipeline
+
+### Build Pipeline (`service-build-pipeline.yml`)
+- Trigger: Pull requests to main
+- Steps: Build → Test → SonarCloud analysis → Mend vulnerability scan
+
+### Publish Pipeline (`service-publish-pipeline.yml`)
+- Trigger: Push to main branch
+- Steps: Build → Test → Publish → SonarCloud → Mend → Artifact upload
+
+Both pipelines use:
+- Ubuntu-latest runner
+- .NET 8.0 SDK
+- SonarCloud for code quality
+- Mend for dependency scanning
+
+## Dependencies
+
+| Package | Version | Purpose |
+|---------|---------|---------|
+| Microsoft.Azure.Cosmos.Table | 1.0.8 | Azure Table Storage client |
+| Newtonsoft.Json | 13.0.3 | JSON serialization |
+| Swashbuckle.AspNetCore | 6.5.0 | Swagger/OpenAPI documentation |
+
+## Configuration
+
+**appsettings.json:**
+```json
+{
+  "ConnectionStrings": {
+    "StorageConnectionString": "UseDevelopmentStorage=true"
+  }
+}
+```
+
+For production, set `StorageConnectionString` to your Azure Storage account connection string.
+
+## Common Development Tasks
+
+### Adding a New Audit Table
+
+1. Create entity class in `Storage/Entity/` extending `TableEntity`
+2. Create storage class in `Storage/` extending `AzureTableStorageAbstract`
+3. Register in `Startup.cs` as singleton
+4. Add controller endpoint in `AuditController.cs`
+
+### Modifying Response Behavior
+
+1. Update `ResponseSettingsModel` and `ResponseSettingsEntity` with new fields
+2. Update `ResponseSettingsStorage` for persistence
+3. Apply new settings in `TokenController` endpoints
+
+### Testing Locally
+
+1. Start Azure Storage Emulator or Azurite
+2. Run the service: `dotnet run --project RemoteProvisioningServiceMock`
+3. Configure test settings via PUT to `/business/{bid}/cardholder/{cid}/settings`
+4. Execute test requests against `/token/*` endpoints
+5. Verify via `/audit/*` endpoints
