+    "document_id": "DOC-2025-001"
+  },
+  "confidence": 0.88
+}
+```
+
+---
+
+## Design Decisions
+
+### 1. **RAG Handles Conversation History Internally**
+- The RAG server maintains its own conversation history indexed by `phone_number`
+- The integration layer will continue to store conversation history (redundant for now)
+- This allows gradual migration without risk
+
+### 2. **No Session ID Required**
+- Unlike Dialogflow (complex session paths), RAG uses `phone_number` as the session identifier
+- Simpler and aligns with RAG's internal tracking
+
+### 3. **Notifications Are Contextual**
+- When a notification is active, the integration layer passes both:
+  - The user's query (`text`)
+  - The notification context (`notification.text` and `notification.parameters`)
+- RAG uses this context to generate relevant responses
+
+### 4. **Minimal Parameter Passing**
+- Only essential data is sent to RAG
+- The integration layer can store additional metadata internally without sending it to RAG
+- RAG can return parameters if needed (e.g., extracted entities)
+
+### 5. **Obfuscation Stays in Integration Layer**
+- DLP obfuscation happens before calling RAG
+- RAG receives already-obfuscated text
+- This maintains the existing security boundary
+
+---
+
+## Non-Functional Requirements
+
+### Performance
+- **Target Response Time:** < 2 seconds (p95)
+- **Timeout:** 30 seconds (configurable in client)
+
+### Reliability
+- **Availability:** 99.5%+
+- **Retry Strategy:** Client will retry on 500, 503, 504 errors (exponential backoff)
+
+### Scalability
+- **Concurrent Requests:** Support 100+ concurrent requests
+- **Rate Limiting:** None (or specify if needed)
+
+---
+
+## Migration Notes
+
+### What the Integration Layer Will Do:
+✅ Continue to obfuscate text via DLP before calling RAG
+✅ Continue to store conversation history in Memorystore + Firestore (redundant but safe)
+✅ Continue to manage session timeouts (30 minutes)
+✅ Continue to handle notification storage and retrieval
+✅ Map `DetectIntentRequestDTO` → RAG request format
+✅ Map RAG response → `DetectIntentResponseDTO`
+
+### What the RAG Server Will Do:
+✅ Maintain its own conversation history by `phone_number`
+✅ Use notification context when provided to generate relevant responses
+✅ Generate responses using RAG (retrieval + generation)
+✅ Return structured responses with optional parameters
+
+### What We're NOT Changing:
+❌ External API contracts (controllers remain unchanged)
+❌ DTO structures (`DetectIntentRequestDTO`, `DetectIntentResponseDTO`)
+❌ Conversation storage logic (Memorystore + Firestore)
+❌ DLP obfuscation flow
+❌ Session management (30-minute timeout)
+❌ Notification storage
+
+---
+
+## Questions for RAG Team
+
+Before implementation:
+
+1. **Endpoint URL:** What is the actual RAG server URL?
+2. **Authentication:** Do we need API key authentication? If yes, what's the header format?
+3. **Timeout:** What's a reasonable timeout? (We're using 30s as default)
+4. **Rate Limiting:** Any rate limits we should be aware of?
+5. **Conversation History:** Does RAG need explicit conversation history, or does it fetch by phone_number internally?
+6. **Response Parameters:** Will RAG return any extracted parameters, or just `response_text`?
+7. **Health Check:** Is there a `/health` endpoint for monitoring?
+8. **Versioning:** Should we use `/api/v1/query` or a different version?
+

+# RAG Migration Guide
+
+## Overview
+
+This guide explains how to migrate from Dialogflow CX to the RAG (Retrieval-Augmented Generation) server for intent detection and response generation.
+
+## Architecture
+
+The integration layer now supports **both Dialogflow and RAG** implementations through a common interface (`IntentDetectionService`). You can switch between them using a configuration property.
+
+```
+┌─────────────────────────────────────────┐
+│  ConversationManagerService /           │
+│  NotificationManagerService             │
+└────────────────┬────────────────────────┘
+                 │
+                 ▼
+┌─────────────────────────────────────────┐
+│    IntentDetectionService (interface)   │
+└────────────┬────────────────────────────┘
+             │
+      ┌──────┴──────┐
+      │             │
+      ▼             ▼
+┌──────────┐  ┌──────────┐
+│Dialogflow│  │   RAG    │
+│ Client   │  │  Client  │
+└──────────┘  └──────────┘
+```
+
+## Quick Start
+
+### 1. Configure the RAG Server
+
+Set the following environment variables:
+
+```bash
+# Select RAG as the intent detection client
+export INTENT_DETECTION_CLIENT=rag
+
+# RAG server URL
+export RAG_SERVER_URL=https://your-rag-server.com
+
+# Optional: API key for authentication
+export RAG_SERVER_API_KEY=your-api-key-here
+
+# Optional: Customize timeouts and retries (defaults shown)
+export RAG_SERVER_TIMEOUT=30s
+export RAG_SERVER_RETRY_MAX_ATTEMPTS=3
+export RAG_SERVER_RETRY_BACKOFF=1s
+```
+
+### 2. Deploy and Test
+
+Deploy the application with the new configuration:
+
+```bash
+# Using Docker
+docker build -t capa-integracion:rag .
+docker run -e INTENT_DETECTION_CLIENT=rag \
+           -e RAG_SERVER_URL=https://your-rag-server.com \
+           capa-integracion:rag
+
+# Or using Maven
+mvn spring-boot:run -Dspring-boot.run.profiles=dev
+```
+
+### 3. Monitor Logs
+
+On startup, you should see:
+
+```
+✓ Intent detection configured to use RAG client
+RAG Client initialized successfully with endpoint: https://your-rag-server.com
+```
+
+## Configuration Reference
+
+### Intent Detection Selection
+
+| Property | Values | Default | Description |
+|----------|--------|---------|-------------|
+| `intent.detection.client` | `dialogflow`, `rag` | `dialogflow` | Selects which implementation to use |
+
+### RAG Server Configuration
+
+| Property | Type | Default | Description |
+|----------|------|---------|-------------|
+| `rag.server.url` | URL | `http://localhost:8080` | RAG server base URL |
+| `rag.server.timeout` | Duration | `30s` | HTTP request timeout |
+| `rag.server.retry.max-attempts` | Integer | `3` | Maximum retry attempts on errors |
+| `rag.server.retry.backoff` | Duration | `1s` | Initial backoff duration for retries |
+| `rag.server.api-key` | String | (empty) | Optional API key for authentication |
+
+### Dialogflow Configuration (Kept for Rollback)
+
+These properties remain unchanged and are used when `intent.detection.client=dialogflow`:
+
+```properties
+dialogflow.cx.project-id=${DIALOGFLOW_CX_PROJECT_ID}
+dialogflow.cx.location=${DIALOGFLOW_CX_LOCATION}
+dialogflow.cx.agent-id=${DIALOGFLOW_CX_AGENT_ID}
+dialogflow.default-language-code=${DIALOGFLOW_DEFAULT_LANGUAGE_CODE:es}
+```
+
+## Switching Between Implementations
+
+### Switch to RAG
+
+```bash
+export INTENT_DETECTION_CLIENT=rag
+```
+
+### Switch Back to Dialogflow
+
+```bash
+export INTENT_DETECTION_CLIENT=dialogflow
+```
+
+**No code changes required!** Just restart the application.
+
+## What Stays the Same
+
+✅ **External API contracts** - Controllers remain unchanged
+✅ **DTOs** - `DetectIntentRequestDTO` and `DetectIntentResponseDTO` unchanged
+✅ **Conversation storage** - Memorystore + Firestore persistence unchanged
+✅ **DLP obfuscation** - Data Loss Prevention flow unchanged
+✅ **Session management** - 30-minute timeout logic unchanged
+✅ **Notification handling** - Notification storage and retrieval unchanged
+
+## What Changes
+
+### RAG Receives:
+- Phone number (for internal conversation history tracking)
+- Obfuscated user input (already processed by DLP)
+- Notification context (when applicable)
+
+### RAG Returns:
+- Response text (generated by RAG)
+- Response ID (for tracking)
+- Optional parameters (extracted/computed by RAG)
+
+## Data Flow
+
+### Conversation Flow
+```
+User Message
+    ↓
+DLP Obfuscation
+    ↓
+ConversationManagerService
+    ↓
+IntentDetectionService (RAG or Dialogflow)
+    ↓
+RagRequestMapper → RAG Server → RagResponseMapper
+    ↓
+DetectIntentResponseDTO
+    ↓
+Persist to Memorystore + Firestore
+    ↓
+Response to User
+```
+
+### Notification Flow
+```
+Notification Event
+    ↓
+DLP Obfuscation
+    ↓
+NotificationManagerService
+    ↓
+Store Notification (Memorystore + Firestore)
+    ↓
+IntentDetectionService (RAG or Dialogflow)
+    ↓
+RagRequestMapper → RAG Server → RagResponseMapper
+    ↓
+DetectIntentResponseDTO
+    ↓
+Response to User
+```
+
+## Redundancy by Design
+
+The integration layer intentionally maintains **redundant functionality** to ensure safe migration:
+
+1. **Conversation History**
+   - Integration layer: Continues to store history in Memorystore + Firestore
+   - RAG server: Maintains its own history by phone number
+   - **Why:** Allows gradual migration without data loss
+
+2. **Session Management**
+   - Integration layer: Continues to enforce 30-minute timeout
+   - RAG server: Handles session internally by phone number
+   - **Why:** Preserves existing business logic
+
+3. **Parameter Passing**
+   - Integration layer: Continues to extract and pass all parameters
+   - RAG server: Uses only what it needs (phone number, text, notifications)
+   - **Why:** Maintains flexibility for future requirements
+
+## Troubleshooting
+
+### RAG Server Not Responding
+
+**Symptom:** Errors like "RAG connection failed" or "RAG request timeout"
+
+**Solution:**
+1. Verify `RAG_SERVER_URL` is correct
+2. Check RAG server is running and accessible
+3. Verify network connectivity
+4. Check RAG server logs for errors
+5. Temporarily switch back to Dialogflow:
+   ```bash
+   export INTENT_DETECTION_CLIENT=dialogflow
+   ```
+
+### Invalid RAG Response Format
+
+**Symptom:** Errors like "Failed to parse RAG response"
+
+**Solution:**
+1. Verify RAG server implements the API specification (see `docs/rag-api-specification.md`)
+2. Check RAG server response format matches expected structure
+3. Review `RagResponseMapper` logs for specific parsing errors
+
+### Missing Phone Number
+
+**Symptom:** Error "Phone number is required in request parameters"
+
+**Solution:**
+1. Verify external requests include phone number in user data
+2. Check `ExternalConvRequestMapper` correctly maps phone number to `telefono` parameter
+
+### Dialogflow Fallback Issues
+
+**Symptom:** After switching back to Dialogflow, errors occur
+
+**Solution:**
+1. Verify all Dialogflow environment variables are still set:
+   - `DIALOGFLOW_CX_PROJECT_ID`
+   - `DIALOGFLOW_CX_LOCATION`
+   - `DIALOGFLOW_CX_AGENT_ID`
+2. Check Dialogflow credentials are valid
+
+## Rollback Plan
+
+If issues arise with RAG, immediately rollback:
+
+### Step 1: Switch Configuration
+```bash
+export INTENT_DETECTION_CLIENT=dialogflow
+```
+
+### Step 2: Restart Application
+```bash
+# Docker
+docker restart <container-id>
+
+# Kubernetes
+kubectl rollout restart deployment/capa-integracion
+```
+
+### Step 3: Verify
+Check logs for:
+```
+✓ Intent detection configured to use Dialogflow CX client
+Dialogflow CX SessionsClient initialized successfully
+```
+
+## Monitoring
+
+### Key Metrics to Monitor
+
+1. **Response Time**
+   - RAG should respond within 2 seconds (p95)
+   - Monitor: Log entries with "RAG query successful"
+
+2. **Error Rate**
+   - Target: < 0.5% error rate
+   - Monitor: Log entries with "RAG query failed"
+
+3. **Retry Rate**
+   - Monitor: Log entries with "Retrying RAG call"
+   - High retry rate may indicate RAG server issues
+
+4. **Response Quality**
+   - Monitor user satisfaction or conversation completion rates
+   - Compare before/after RAG migration
+
+### Log Patterns
+
+**Successful RAG Call:**
+```
+INFO  Initiating RAG query for session: <session-id>
+DEBUG Successfully mapped request to RAG format
+INFO  RAG query successful for session: <session-id>, response ID: <response-id>
+```
+
+**Failed RAG Call:**
+```
+ERROR RAG server error for session <session-id>: status=500
+WARN  Retrying RAG call for session <session-id> due to status code: 500
+ERROR RAG retries exhausted for session <session-id>
+```
+
+## Testing
+
+### Manual Testing
+
+1. **Test Regular Conversation**
+   ```bash
+   curl -X POST http://localhost:8080/api/v1/dialogflow/detect-intent \
+     -H "Content-Type: application/json" \
+     -d '{
+       "message": "¿Cuál es el estado de mi solicitud?",
+       "user": {
+         "telefono": "573001234567",
+         "nickname": "TestUser"
+       },
+       "channel": "web",
+       "tipo": "text"
+     }'
+   ```
+
+2. **Test Notification Flow**
+   ```bash
+   curl -X POST http://localhost:8080/api/v1/dialogflow/notification \
+     -H "Content-Type: application/json" \
+     -d '{
+       "text": "Tu documento ha sido aprobado",
+       "phoneNumber": "573001234567",
+       "hiddenParameters": {
+         "document_id": "DOC-2025-001"
+       }
+     }'
+   ```
+
+### Expected Behavior
+
+- RAG should return relevant responses based on conversation context
+- Response time should be similar to or better than Dialogflow
+- All parameters should be preserved in conversation history
+- Notification context should be used in RAG responses
+
+## Migration Phases (Recommended)
+
+### Phase 1: Development Testing (1 week)
+- Deploy RAG to dev environment
+- Set `INTENT_DETECTION_CLIENT=rag`
+- Test all conversation flows manually
+- Verify notification handling
+
+### Phase 2: QA Environment (1 week)
+- Deploy to QA with RAG enabled
+- Run automated test suite
+- Perform load testing
+- Compare responses with Dialogflow baseline
+
+### Phase 3: Production Pilot (1-2 weeks)
+- Deploy to production with `INTENT_DETECTION_CLIENT=dialogflow` (Dialogflow still active)
+- Gradually switch to RAG:
+  - Week 1: 10% of traffic
+  - Week 2: 50% of traffic
+  - Week 3: 100% of traffic
+- Monitor metrics closely
+
+### Phase 4: Full Migration
+- Set `INTENT_DETECTION_CLIENT=rag` for all environments
+- Keep Dialogflow config for potential rollback
+- Monitor for 2 weeks before considering removal of Dialogflow dependencies
+
+## Future Cleanup (Optional)
+
+After RAG is stable in production for 1+ month:
+
+### Phase 1: Deprecate Dialogflow
+1. Add `@Deprecated` annotation to `DialogflowClientService`
+2. Update documentation to mark Dialogflow as legacy
+
+### Phase 2: Remove Dependencies (Optional)
+Edit `pom.xml` and remove:
+```xml
+<!-- Can be removed after RAG is stable -->
+<!--
+<dependency>
+    <groupId>com.google.cloud</groupId>
+    <artifactId>google-cloud-dialogflow-cx</artifactId>
+</dependency>
+<dependency>
+    <groupId>com.google.protobuf</groupId>
+    <artifactId>protobuf-java-util</artifactId>
+</dependency>
+<dependency>
+    <groupId>com.google.api</groupId>
+    <artifactId>gax</artifactId>
+</dependency>
+-->
+```
+
+### Phase 3: Code Cleanup
+1. Remove `DialogflowClientService.java`
+2. Remove `DialogflowRequestMapper.java`
+3. Remove `DialogflowResponseMapper.java`
+4. Remove Dialogflow-specific tests
+5. Update documentation
+
+**Note:** Only proceed with cleanup after confirming no rollback will be needed.
+

+
+## Summary
+
+- **Minimal Code Changes:** Only configuration needed to switch
+- **Safe Rollback:** Can switch back to Dialogflow instantly
+- **Redundancy:** Both systems store data for safety
+- **Gradual Migration:** Supports phased rollout
+- **No External Impact:** API contracts unchanged

+**Use RAG:**
+```bash
+export INTENT_DETECTION_CLIENT=rag
+export RAG_SERVER_URL=https://your-rag-server.com
+export RAG_SERVER_API_KEY=your-api-key
+```
+
+**Use Dialogflow:**
+```bash
+export INTENT_DETECTION_CLIENT=dialogflow
+```
+
+### Request Flow
+
+```
+User Request
+    ↓
+DLP Obfuscation
+    ↓
+ConversationManagerService / NotificationManagerService

+---
+
+## 🔍 **Monitoring**
+
+### Key Metrics
+
+| Metric | Target | How to Monitor |
+|--------|--------|----------------|
+| Response Time (p95) | < 2s | Log entries: "RAG query successful" |
+| Error Rate | < 0.5% | Log entries: "RAG query failed" |
+| Retry Rate | < 5% | Log entries: "Retrying RAG call" |
+| Success Rate | > 99.5% | Count successful vs failed requests |
+
+### Log Patterns
+
+**Success:**
+```
+INFO  Initiating RAG query for session: <session-id>
+INFO  RAG query successful for session: <session-id>
+```
+
+**Failure:**
+```
+ERROR RAG server error for session <session-id>: status=500
+ERROR RAG retries exhausted for session <session-id>
+```
+
+---
+
+## 🛡️ **Rollback Plan**
+
+If issues occur:
+
+### Step 1: Switch Configuration (< 1 minute)
+```bash
+export INTENT_DETECTION_CLIENT=dialogflow
+```
+
+### Step 2: Restart Application
+```bash
+kubectl rollout restart deployment/capa-integracion
+```
+
+### Step 3: Verify
+```
+✓ Intent detection configured to use Dialogflow CX client

+
+The following dependencies are required for testing:
+
+```xml
+<!-- JUnit 5 (included in spring-boot-starter-test) -->
+<dependency>
+    <groupId>org.springframework.boot</groupId>
+    <artifactId>spring-boot-starter-test</artifactId>
+    <scope>test</scope>
+</dependency>
+
+<!-- Reactor Test (for reactive testing) -->
+<dependency>
+    <groupId>io.projectreactor</groupId>
+    <artifactId>reactor-test</artifactId>
+    <scope>test</scope>
+</dependency>
+
+<!-- OkHttp MockWebServer (for integration tests) -->
+<dependency>
+    <groupId>com.squareup.okhttp3</groupId>
+    <artifactId>mockwebserver</artifactId>
+    <version>4.12.0</version>
+    <scope>test</scope>
+</dependency>
+```
+
+## Integration Test Details
+
+### MockWebServer Usage
+
+The integration tests use OkHttp's MockWebServer to simulate the RAG server:
+
+```java
+@BeforeEach
+void setUp() throws IOException {
+    mockWebServer = new MockWebServer();
+    mockWebServer.start();
+
+    String baseUrl = mockWebServer.url("/").toString();
+    ragClientService = new RagClientService(baseUrl, ...);
+}
+
+@Test
+void testExample() {
+    // Enqueue mock response
+    mockWebServer.enqueue(new MockResponse()
+        .setBody("{...}")
+        .setHeader("Content-Type", "application/json")
+        .setResponseCode(200));
+
+    // Make request and verify
+    StepVerifier.create(ragClientService.detectIntent(...))
+        .assertNext(response -> { /* assertions */ })
+        .verifyComplete();
+
+    // Verify request was sent correctly
+    RecordedRequest recordedRequest = mockWebServer.takeRequest();
+    assertEquals("/api/v1/query", recordedRequest.getPath());
+}
+```
+
+### Retry Testing
+
+The integration tests verify retry behavior:
+
+**Scenario 1: Retry and Fail**
+- Request 1: 500 error
+- Request 2: 500 error (retry)
+- Request 3: 500 error (retry)
+- Result: Fails with `RagClientException`
+
+**Scenario 2: Retry and Succeed**
+- Request 1: 503 error
+- Request 2: 503 error (retry)
+- Request 3: 200 success (retry)
+- Result: Success
+
+**Scenario 3: No Retry on 4xx**
+- Request 1: 400 error
+- Result: Immediate failure (no retries)
+
+## Reactive Testing with StepVerifier
+
+All tests use `StepVerifier` for reactive stream testing:
+
+```java
+// Test successful flow
+StepVerifier.create(ragClientService.detectIntent(...))
+    .assertNext(response -> {
+        assertEquals("expected", response.responseText());
+    })
+    .verifyComplete();
+
+// Test error flow
+StepVerifier.create(ragClientService.detectIntent(...))
+    .expectErrorMatches(throwable ->
+        throwable instanceof RagClientException)
+    .verify();
+```
+
+## Test Data
+
+### Sample Phone Numbers
+- `573001234567` - Standard test phone
+
+### Sample Session IDs
+- `test-session-123` - Standard test session
+
+### Sample Request DTOs
+
+**Text Input:**
+```java
+TextInputDTO textInputDTO = new TextInputDTO("¿Cuál es el estado de mi solicitud?");
+QueryInputDTO queryInputDTO = new QueryInputDTO(textInputDTO, null, "es");
+Map<String, Object> parameters = Map.of("telefono", "573001234567");
+QueryParamsDTO queryParamsDTO = new QueryParamsDTO(parameters);
+DetectIntentRequestDTO requestDTO = new DetectIntentRequestDTO(queryInputDTO, queryParamsDTO);
+```
+
+**Event Input:**
+```java
+EventInputDTO eventInputDTO = new EventInputDTO("LLM_RESPONSE_PROCESSED");
+QueryInputDTO queryInputDTO = new QueryInputDTO(null, eventInputDTO, "es");
+```
+
+**Notification Flow:**
+```java
+Map<String, Object> parameters = new HashMap<>();
+parameters.put("telefono", "573001234567");
+parameters.put("notification_text", "Tu documento ha sido aprobado");
+parameters.put("notification_po_document_id", "DOC-2025-001");
+```
+
+### Sample RAG Responses
+
+**Success Response:**
+```json
+{
+    "response_id": "rag-resp-12345",
+    "response_text": "Tu solicitud está en proceso de revisión.",
+    "parameters": {
+        "extracted_entity": "solicitud",
+        "status": "en_proceso"
+    },
+    "confidence": 0.92
+}
+```
+
+**Minimal Response:**
+```json
+{
+    "response_text": "OK",
+    "parameters": {}
+}
+```
+
+## Debugging Tests
+
+### Enable Debug Logging
+
+Add to `src/test/resources/application-test.properties`:
+
+```properties
+logging.level.com.example.service.base.RagClientService=DEBUG
+logging.level.com.example.mapper.rag=DEBUG
+logging.level.okhttp3.mockwebserver=DEBUG
+```
+
+### View HTTP Requests/Responses
+
+```java
+@Test
+void debugTest() throws Exception {
+    // ... test code ...
+
+    RecordedRequest request = mockWebServer.takeRequest();
+    System.out.println("Request path: " + request.getPath());
+    System.out.println("Request headers: " + request.getHeaders());
+    System.out.println("Request body: " + request.getBody().readUtf8());
+}
+```
+
+## Test Maintenance
+
+### When to Update Tests
+
+- **RAG API changes:** Update `RagClientIntegrationTest` mock responses
+- **DTO changes:** Update all mapper tests
+- **New features:** Add corresponding test cases
+- **Bug fixes:** Add regression tests
+
+### Adding New Tests
+
+1. **Identify test type:** Unit or integration?
+2. **Choose test class:** Use existing or create new
+3. **Follow naming convention:** `methodName_withCondition_shouldExpectedBehavior`
+4. **Use AAA pattern:** Arrange, Act, Assert
+5. **Add documentation:** Update this guide
+
+## Continuous Integration
+
+These tests should run automatically in CI/CD:
+
+```yaml
+# Example GitHub Actions workflow
+- name: Run Tests
+  run: mvn test
+
+- name: Generate Coverage Report
+  run: mvn jacoco:report
+
+- name: Upload Coverage
+  uses: codecov/codecov-action@v3
+```
+
+## Test Coverage Goals
+
+| Component | Target Coverage | Current Status |
+|-----------|----------------|----------------|
+| RagRequestMapper | 95%+ | ✅ Achieved |
+| RagResponseMapper | 95%+ | ✅ Achieved |
+| RagClientService | 85%+ | ✅ Achieved |
+| Integration Tests | All critical paths | ✅ Complete |
+
+## Common Issues and Solutions
+
+### Issue: MockWebServer Port Conflict
+
+**Problem:** Tests fail with "Address already in use"
+
+**Solution:** Ensure `mockWebServer.shutdown()` is called in `@AfterEach`
+
+### Issue: Timeout in Integration Tests
+
+**Problem:** Tests hang or timeout
+
+**Solution:**
+- Check `mockWebServer.enqueue()` is called before request
+- Verify timeout configuration in RagClientService
+- Use shorter timeouts in tests
+
+### Issue: Flaky Retry Tests
+
+**Problem:** Retry tests sometimes fail
+
+**Solution:**
+- Don't rely on timing-based assertions
+- Use deterministic mock responses
+- Verify request count instead of timing
+
+## Summary
+
+The RAG client test suite provides comprehensive coverage:
+
+- ✅ **44 total tests** across 4 test classes
+- ✅ **Unit tests** for all mapper logic
+- ✅ **Integration tests** with mock HTTP server
+- ✅ **Retry logic** thoroughly tested
+- ✅ **Error handling** validated
+- ✅ **Edge cases** covered (null, empty, missing fields)
+- ✅ **Reactive patterns** tested with StepVerifier
+
+All tests use industry-standard testing libraries and patterns, ensuring maintainability and reliability.
