+# Async Image Processing Implementation
+
+## Overview
+
+The image processing system has been updated to handle external images asynchronously, preventing timeouts when processing stories with many images. This provides real-time progress updates to users showing which images are being processed.
+
+## Backend Components
+
+### 1. `ImageProcessingProgressService`
+- Tracks progress for individual story image processing sessions
+- Thread-safe with `ConcurrentHashMap` for multi-user support
+- Provides progress information: total images, processed count, current image, status, errors
+
+### 2. `AsyncImageProcessingService`
+- Handles asynchronous image processing using Spring's `@Async` annotation
+- Counts external images before processing
+- Provides progress callbacks during processing
+- Updates story content when processing completes
+- Automatic cleanup of progress data after completion
+
+### 3. Enhanced `ImageService`
+- Added `processContentImagesWithProgress()` method with callback support
+- Progress callbacks provide real-time updates during image download/processing
+- Maintains compatibility with existing synchronous processing
+
+### 4. Updated `StoryController`
+- `POST /api/stories` and `PUT /api/stories/{id}` now trigger async image processing
+- `GET /api/stories/{id}/image-processing-progress` endpoint for progress polling
+- Processing starts immediately after story save and returns control to user
+
+## Frontend Components
+
+### 1. `ImageProcessingProgressTracker` (Utility Class)
+```typescript
+const tracker = new ImageProcessingProgressTracker(storyId);
+tracker.onProgress((progress) => {
+  console.log(`Processing ${progress.processedImages}/${progress.totalImages}`);
+});
+tracker.onComplete(() => console.log('Done!'));
+tracker.start();
+```
+
+### 2. `ImageProcessingProgressComponent` (React Component)
+```tsx
+<ImageProcessingProgressComponent
+  storyId={storyId}
+  autoStart={true}
+  onComplete={() => refreshStory()}
+/>
+```
+
+## User Experience
+
+### Before (Synchronous)
+1. User saves story with external images
+2. Request hangs for 30+ seconds processing images
+3. Browser may timeout
+4. No feedback about progress
+5. User doesn't know if it's working
+
+### After (Asynchronous)
+1. User saves story with external images
+2. Save completes immediately
+3. Progress indicator appears: "Processing 5 images. Currently image 2 of 5..."
+4. User can continue using the application
+5. Progress updates every second
+6. Story automatically refreshes when processing completes
+
+## API Endpoints
+
+### Progress Endpoint
+```
+GET /api/stories/{id}/image-processing-progress
+```
+
+**Response when processing:**
+```json
+{
+  "isProcessing": true,
+  "totalImages": 5,
+  "processedImages": 2,
+  "currentImageUrl": "https://example.com/image.jpg",
+  "status": "Processing image 3 of 5",
+  "progressPercentage": 40.0,
+  "completed": false,
+  "error": ""
+}
+```
+
+**Response when completed:**
+```json
+{
+  "isProcessing": false,
+  "totalImages": 5,
+  "processedImages": 5,
+  "currentImageUrl": "",
+  "status": "Completed: 5 images processed",
+  "progressPercentage": 100.0,
+  "completed": true,
+  "error": ""
+}
+```
+
+**Response when no processing:**
+```json
+{
+  "isProcessing": false,
+  "message": "No active image processing"
+}
+```
+
+## Integration Examples
+
+### React Hook Usage
+```tsx
+import { useImageProcessingProgress } from '../utils/imageProcessingProgress';
+
+function StoryEditor({ storyId }) {
+  const { progress, isTracking, startTracking } = useImageProcessingProgress(storyId);
+
+  const handleSave = async () => {
+    await saveStory();
+    startTracking(); // Start monitoring progress
+  };
+
+  return (
+    <div>
+      {isTracking && progress && (
+        <div className="progress-indicator">
+          Processing {progress.processedImages}/{progress.totalImages} images...
+        </div>
+      )}
+      <button onClick={handleSave}>Save Story</button>
+    </div>
+  );
+}
+```
+
+### Manual Progress Tracking
+```typescript
+// After saving a story with external images
+const tracker = new ImageProcessingProgressTracker(storyId);
+
+tracker.onProgress((progress) => {
+  updateProgressBar(progress.progressPercentage);
+  showStatus(progress.status);
+  if (progress.currentImageUrl) {
+    showCurrentImage(progress.currentImageUrl);
+  }
+});
+
+tracker.onComplete((finalProgress) => {
+  hideProgressBar();
+  showNotification('Image processing completed!');
+  refreshStoryContent(); // Reload story with processed images
+});
+
+tracker.onError((error) => {
+  hideProgressBar();
+  showError(`Image processing failed: ${error}`);
+});
+
+tracker.start();
+```
+
+## Configuration
+
+### Polling Interval
+Default: 1 second (1000ms)
+```typescript
+const tracker = new ImageProcessingProgressTracker(storyId, 500); // Poll every 500ms
+```
+
+### Timeout
+Default: 5 minutes (300000ms)
+```typescript
+const tracker = new ImageProcessingProgressTracker(storyId, 1000, 600000); // 10 minute timeout
+```
+
+### Spring Async Configuration
+The backend uses Spring's default async executor. For production, consider configuring a custom thread pool in your application properties:
+
+```yaml
+spring:
+  task:
+    execution:
+      pool:
+        core-size: 4
+        max-size: 8
+        queue-capacity: 100
+```
+
+## Error Handling
+
+### Backend Errors
+- Network timeouts downloading images
+- Invalid image formats
+- Disk space issues
+- All errors are logged and returned in progress status
+
+### Frontend Errors
+- Network failures during progress polling
+- Timeout if processing takes too long
+- Graceful degradation - user can continue working
+
+## Benefits
+
+1. **No More Timeouts**: Large image processing operations won't timeout HTTP requests
+2. **Better UX**: Users get real-time feedback about processing progress
+3. **Improved Performance**: Users can continue using the app while images process
+4. **Error Visibility**: Clear error messages when image processing fails
+5. **Scalability**: Multiple users can process images simultaneously without blocking
+
+## Future Enhancements
+
+1. **WebSocket Support**: Replace polling with WebSocket for real-time push updates
+2. **Batch Processing**: Queue multiple stories for batch image processing
+3. **Retry Logic**: Automatic retry for failed image downloads
+4. **Progress Persistence**: Save progress to database for recovery after server restart
+5. **Image Optimization**: Automatic resize/compress images during processing

+# StoryCove Deployment Guide
+
+## Quick Deployment
+
+StoryCove includes an automated deployment script that handles Solr volume cleanup and ensures fresh search indices on every deployment.
+
+### Using the Deployment Script
+
+```bash
+./deploy.sh
+```
+
+This script will:
+1. Stop all running containers
+2. **Remove the Solr data volume** (forcing fresh core creation)
+3. Build and start all containers
+4. Wait for services to become healthy
+5. Trigger automatic bulk reindexing
+
+### What Happens During Deployment
+
+#### 1. Solr Volume Cleanup
+The script removes the `storycove_solr_data` volume, which:
+- Ensures all Solr cores are recreated from scratch
+- Prevents stale configuration issues
+- Guarantees schema changes are applied
+
+#### 2. Automatic Bulk Reindexing
+When the backend starts, it automatically:
+- Detects that Solr is available
+- Fetches all entities from the database (Stories, Authors, Collections)
+- Bulk indexes them into Solr
+- Logs progress and completion
+
+### Monitoring the Deployment
+
+Watch the backend logs to see reindexing progress:
+```bash
+docker-compose logs -f backend
+```
+
+You should see output like:
+```
+========================================
+Starting automatic bulk reindexing...
+========================================
+📚 Indexing stories...
+✅ Indexed 150 stories
+👤 Indexing authors...
+✅ Indexed 45 authors
+📂 Indexing collections...
+✅ Indexed 12 collections
+========================================
+✅ Bulk reindexing completed successfully in 2345ms
+📊 Total indexed: 150 stories, 45 authors, 12 collections
+========================================
+```
+
+## Manual Deployment (Without Script)
+
+If you prefer manual control:
+
+```bash
+# Stop containers
+docker-compose down
+
+# Remove Solr volume
+docker volume rm storycove_solr_data
+
+# Start containers
+docker-compose up -d --build
+```
+
+The automatic reindexing will still occur on startup.
+
+## Troubleshooting
+
+### Reindexing Fails
+
+If bulk reindexing fails:
+1. Check Solr is running: `docker-compose logs solr`
+2. Verify Solr health: `curl http://localhost:8983/solr/admin/ping`
+3. Check backend logs: `docker-compose logs backend`
+
+The application will still start even if reindexing fails - you can manually trigger reindexing through the admin API.
+
+### Solr Cores Not Created
+
+If Solr cores aren't being created properly:
+1. Check the `solr.Dockerfile` to ensure cores are created
+2. Verify the Solr image builds correctly: `docker-compose build solr`
+3. Check Solr Admin UI: http://localhost:8983
+
+### Performance Issues
+
+If reindexing takes too long:
+- The bulk indexing is already optimized (batch operations)
+- Consider increasing Solr memory in `docker-compose.yml`:
+  ```yaml
+  environment:
+    - SOLR_HEAP=1024m
+  ```
+
+## Development Workflow
+
+### Daily Development
+Just use the normal commands:
+```bash
+docker-compose up -d
+```
+
+The automatic reindexing still happens, but it's fast on small datasets.
+
+### Schema Changes
+When you modify Solr schema or add new cores:
+```bash
+./deploy.sh
+```
+
+This ensures a clean slate.
+
+### Skipping Reindexing
+
+Reindexing is automatic and cannot be disabled. It's designed to be fast and unobtrusive. The application starts immediately - reindexing happens in the background.
+
+## Environment Variables
+
+No additional environment variables are needed for the deployment script. All configuration is in `docker-compose.yml`.
+
+## Backup Considerations
+
+**Important**: Since the Solr volume is recreated on every deployment, you should:
+- Never rely on Solr as the source of truth
+- Always maintain data in PostgreSQL
+- Solr is treated as a disposable cache/index
+
+This is the recommended approach for search indices.

+
+## Critical Findings Summary
+
+### 🚨 CRITICAL (Must Fix)
+
+1. **Collections Search Not Implemented**
+   - **Location:** `CollectionService.java:56-61`
+   - **Impact:** GET /api/collections always returns empty results
+   - **Specification:** storycove-collections-spec.md lines 52-61 mandates Solr search
+   - **Estimated Fix:** 4-6 hours
+   - **Steps:**
+     1. Create Solr Collections core with schema
+     2. Implement indexing in SearchServiceAdapter
+     3. Wire up CollectionService.searchCollections()
+     4. Test pagination and filtering
+
+### ⚠️ HIGH Priority (Recommended)
+
+2. **Missing Test Coverage** (~25% vs target 80%)
+   - HtmlSanitizationServiceTest - security critical
+   - CollectionServiceTest - feature verification

+   - EPUBImportServiceTest, EPUBExportServiceTest - file processing
+
+3. **API Documentation Updates**
+   - Advanced filters not fully documented
+   - EPUB endpoints missing from API.md
+
+### 📋 MEDIUM Priority (Optional)
+
+4. **SearchController Minimal**
+   - Only has reindex and health check
+   - Actual search in StoryController
+
+5. **Frontend Test Coverage**
+   - No component tests
+   - No integration tests
+   - Recommend: Jest + React Testing Library

+# StoryCove Housekeeping Report - Phase 1: Documentation & State Assessment
+**Date**: 2025-01-10
+**Completed By**: Claude Code (Housekeeping Analysis)
+
+## Executive Summary
+
+Phase 1 assessment has been completed, providing a comprehensive review of the StoryCove application's current implementation status against specifications. The application is **well-implemented** with most core features working, but there is **1 CRITICAL ISSUE** and several areas requiring attention.
+
+### Critical Finding
+🚨 **Collections Search Not Implemented**: The Collections feature does not use Typesense/Solr for search as mandated by the specification. This is a critical architectural requirement that must be addressed.
+
+### Overall Status
+- **Backend Implementation**: ~85% complete with specification
+- **Entity Models**: ✅ 100% compliant with DATA_MODEL.md
+- **Test Coverage**: ⚠️ 9 tests exist, but many critical services lack tests
+- **Documentation**: ✅ Comprehensive and up-to-date

+| **Library** | (Multi-library support) | ✅ Complete | Implemented for multi-library feature |
+
+**Assessment**: Entity layer is **100% specification-compliant** ✅
+
+---
+
+### 1.2 Repository Layer (⚠️ MOSTLY COMPLIANT)
+
+| Repository | Specification Compliance | Issues |
+|------------|-------------------------|--------|
+| **CollectionRepository** | ⚠️ Partial | Contains only ID-based lookups (correct), has note about Typesense |
+| **TagRepository** | ✅ Complete | Proper query methods, no search anti-patterns |
+| **StoryRepository** | ✅ Complete | Appropriate methods |
+| **AuthorRepository** | ✅ Complete | Appropriate methods |
+| **SeriesRepository** | ✅ Complete | Basic CRUD |
+| **ReadingPositionRepository** | ✅ Complete | Story-based lookups |
+| **TagAliasRepository** | ✅ Complete | Name-based lookups for resolution |
+
+**Key Finding**: CollectionRepository correctly avoids search/filter methods (good architectural design), but the corresponding search implementation in CollectionService is not yet complete.
+
+---
+
+### 1.3 Service Layer (🚨 CRITICAL ISSUE FOUND)
+
+| Service | Status | Specification Match | Critical Issues |
+|---------|--------|---------------------|-----------------|
+| **CollectionService** | 🚨 **INCOMPLETE** | 20% | **Collections search returns empty results** (line 56-61) |
+| **TagService** | ✅ Complete | 100% | Full alias, merging, AI suggestions implemented |
+| **StoryService** | ✅ Complete | 95% | Core features complete |
+| **AuthorService** | ✅ Complete | 95% | Core features complete |
+| **EPUBImportService** | ✅ Complete | 100% | Phase 1 & 2 complete per spec |
+| **EPUBExportService** | ✅ Complete | 100% | Single story & collection export working |

+| **HtmlSanitizationService** | ✅ Complete | 100% | Security-critical, appears complete |
+| **SearchServiceAdapter** | ⚠️ Partial | 70% | Solr integration present but Collections not indexed |
+| **ReadingTimeService** | ✅ Complete | 100% | Word count calculations |
+
+#### 🚨 CRITICAL ISSUE Detail: CollectionService.searchCollections()
+
+**File**: `backend/src/main/java/com/storycove/service/CollectionService.java:56-61`
+
+```java
+public SearchResultDto<Collection> searchCollections(String query, List<String> tags, boolean includeArchived, int page, int limit) {
+    // Collections are currently handled at database level, not indexed in search engine
+    // Return empty result for now as collections search is not implemented in Solr
+    logger.warn("Collections search not yet implemented in Solr, returning empty results");
+    return new SearchResultDto<>(new ArrayList<>(), 0, page, limit, query != null ? query : "", 0);
+}
+```
+
+**Impact**:
+- GET /api/collections endpoint always returns 0 results
+- Frontend collections list view will appear empty
+- Violates architectural requirement in storycove-collections-spec.md Section 4.2 and 5.2
+
+**Specification Requirement** (storycove-collections-spec.md:52-61):
+> **IMPORTANT**: This endpoint MUST use Typesense for all search and filtering operations.
+> Do NOT implement search/filter logic using JPA/SQL queries.
+
+---

+
+---
+
+## 5. Architecture Compliance
+
+### 5.1 Search Integration Architecture
+
+**Specification Requirement** (storycove-collections-spec.md):
+> All search, filtering, and listing operations MUST use Typesense as the primary data source.
+
+**Current State**:
+- ✅ **Stories**: Properly use SearchServiceAdapter (Solr)
+- ✅ **Authors**: Properly use SearchServiceAdapter (Solr)
+- 🚨 **Collections**: NOT using SearchServiceAdapter
+
+### 5.2 Anti-Pattern Verification
+
+**Collections Repository** (CollectionRepository.java): ✅ CORRECT
+- Contains ONLY findById methods
+- Has explicit note: "For search/filter/list operations, use TypesenseService instead"
+- No search anti-patterns present
+
+**Comparison with Spec Anti-Patterns** (storycove-collections-spec.md:663-689):
+```java
+// ❌ WRONG patterns NOT FOUND in codebase ✅
+// CollectionRepository correctly avoids:
+// - findByNameContaining()
+// - findByTagsIn()
+// - findByNameContainingAndArchived()
+```
+
+**Issue**: While the repository layer is correctly designed, the service layer implementation is incomplete.
+
+---
+
+## 6. Code Quality Observations
+
+### 6.1 Positive Findings
+1. ✅ **Consistent Entity Design**: All entities use UUID, proper annotations, equals/hashCode
+2. ✅ **Transaction Management**: @Transactional used appropriately
+3. ✅ **Logging**: Comprehensive SLF4J logging throughout
+4. ✅ **Validation**: Jakarta validation annotations used
+5. ✅ **DTOs**: Proper separation between entities and DTOs
+6. ✅ **Error Handling**: Custom exceptions (ResourceNotFoundException, DuplicateResourceException)
+7. ✅ **Gap-Based Positioning**: Collections use proper positioning algorithm (multiples of 1000)
+
+### 6.2 Areas for Improvement
+1. ⚠️ **Test Coverage**: Major gap in service layer tests
+2. 🚨 **Collections Search**: Critical feature not implemented
+3. ⚠️ **Security Tests**: No dedicated tests for HtmlSanitizationService
+4. ⚠️ **Integration Tests**: Limited E2E testing
+
+---
+
+## 7. Dependencies & Technology Stack
+
+### 7.1 Key Dependencies (Observed)
+- ✅ Spring Boot (Jakarta EE)
+- ✅ Hibernate/JPA
+- ✅ PostgreSQL
+- ✅ Solr (in place of Typesense, acceptable alternative)
+- ✅ EPUBLib (for EPUB handling)
+- ✅ Jsoup (for HTML sanitization)
+- ✅ JWT (authentication)
+
+### 7.2 Search Engine Note
+**Specification**: Calls for Typesense
+**Implementation**: Uses Solr (Apache Solr)
+**Assessment**: ✅ Acceptable - Solr provides equivalent functionality
+
+---
+
+## 8. Documentation Status
+
+### 8.1 Specification Documents
+| Document | Status | Notes |
+|----------|--------|-------|
+| storycove-spec.md | ✅ Current | Comprehensive main spec |
+| DATA_MODEL.md | ✅ Current | Matches implementation |
+| API.md | ⚠️ Needs minor updates | Most endpoints documented |
+| TAG_ENHANCEMENT_SPECIFICATION.md | ✅ Current | Marked as completed |
+| EPUB_IMPORT_EXPORT_SPECIFICATION.md | ✅ Current | Phase 1 & 2 marked complete |
+| storycove-collections-spec.md | ⚠️ Needs update | Should note search not implemented |
+| CLAUDE.md | ✅ Current | Good project guidance |
+
+### 8.2 Code Documentation
+- ✅ Controllers: Well documented with Javadoc
+- ✅ Services: Good inline comments
+- ✅ Entities: Adequate field documentation
+- ⚠️ Tests: Limited documentation
+
+---
+
+## 9. Phase 1 Conclusions

-## Target OpenSearch Architecture
-
-### Service Layer Design
-
-**New Components:**
-```
-OpenSearchService.java        - Primary search service (mirrors TypesenseService API)
-OpenSearchConfig.java         - Configuration and client setup
-SearchMigrationService.java   - Handles parallel operation during migration
-SearchServiceAdapter.java     - Abstraction layer for service switching
-```
-
-**Index Strategy:**
-- **Single-node deployment** for development/small installations
-- **Index-per-library** approach: `stories-{libraryId}`, `authors-{libraryId}`, `collections-{libraryId}`
-- **Index templates** for consistent mapping across libraries
-- **Aliases** for easy switching and zero-downtime updates
-
-### OpenSearch Index Mappings
-
-**Stories Index Mapping:**

-```
-
-**Authors Index Mapping:**

-      "updatedAt": {"type": "date"}
-    }

-}
-```
-
-### Query Translation Strategy
-
-**Random Story Queries:**
-```java
-// Typesense (problematic)
-String sortBy = seed != null ? "_rand(" + seed + ")" : "_rand()";
-
-// OpenSearch (reliable)
-QueryBuilder randomQuery = QueryBuilders.functionScoreQuery(
-    QueryBuilders.boolQuery().must(filters),
-    ScoreFunctionBuilders.randomFunction(seed != null ? seed.intValue() : null)
-);
-```
-
-**Complex Filtering:**
-```java
-// Build bool query with multiple filter conditions
-BoolQueryBuilder boolQuery = QueryBuilders.boolQuery()
-    .must(QueryBuilders.multiMatchQuery(query, "title", "description", "authorName"))
-    .filter(QueryBuilders.termsQuery("tagNames", tags))
-    .filter(QueryBuilders.rangeQuery("wordCount").gte(minWords).lte(maxWords))
-    .filter(QueryBuilders.rangeQuery("rating").gte(minRating).lte(maxRating));
-```
-
-**Faceting/Aggregations:**
-```java
-// Tags aggregation
-AggregationBuilder tagsAgg = AggregationBuilders
-    .terms("tags")
-    .field("tagNames")
-    .size(100);
-
-// Rating ranges
-AggregationBuilder ratingRanges = AggregationBuilders
-    .range("rating_ranges")
-    .field("rating")
-    .addRange("unrated", 0, 1)
-    .addRange("low", 1, 3)
-    .addRange("high", 4, 6);
-```

-
-## Data Migration Strategy
-
-### Pre-Migration Validation
-
-**Data Integrity Checks:**
-1. Count validation: Ensure all stories/authors/collections are present
-2. Field validation: Verify all required fields are populated
-3. Relationship validation: Check author-story and series-story relationships
-4. Library separation: Ensure proper multi-library data isolation
-
-**Migration Process:**
-
-1. **Index Creation:**
-```java
-// Create indexes with proper mappings for each library
-for (Library library : libraries) {
-    String storiesIndex = "stories-" + library.getId();
-    createIndexWithMapping(storiesIndex, getStoriesMapping());
-    createIndexWithMapping("authors-" + library.getId(), getAuthorsMapping());
-    createIndexWithMapping("collections-" + library.getId(), getCollectionsMapping());
-}
-```
-
-2. **Bulk Data Loading:**
-```java
-// Load in batches to manage memory usage
-int batchSize = 1000;
-List<Story> allStories = storyService.findByLibraryId(libraryId);
-
-for (int i = 0; i < allStories.size(); i += batchSize) {
-    List<Story> batch = allStories.subList(i, Math.min(i + batchSize, allStories.size()));
-    List<StoryDocument> documents = batch.stream()
-        .map(this::convertToSearchDocument)
-        .collect(Collectors.toList());
-
-    bulkIndexStories(documents, "stories-" + libraryId);
-}
-```
-
-3. **Post-Migration Validation:**
-   - Count comparison between database and OpenSearch
-   - Spot-check random records for field accuracy
-   - Test search functionality with known queries
-   - Verify faceting counts match expected values
-
-### Rollback Strategy
-
-**Immediate Rollback Triggers:**
-- Search error rate > 1%
-- Query performance degradation > 50%
-- Data inconsistency detected
-- Memory usage > 4GB sustained
-
-**Rollback Process:**
-1. Update feature flag to disable OpenSearch
-2. Verify Typesense still operational
-3. Clear OpenSearch indexes to free resources
-4. Investigate and document issues
-
-**Data Consistency During Rollback:**
-- Continue dual-write during investigation
-- Re-sync any missed updates to OpenSearch
-- Validate data integrity before retry
-
----
-
-## Testing Strategy

-
-    @Test
-    void testEndToEndStorySearch() {
-        // Insert test data
-        // Perform search via controller
-        // Validate results
-    }
-}
-```

+# Refresh Token Implementation
+
+## Overview
+
+This document describes the refresh token functionality implemented for StoryCove, allowing users to stay authenticated for up to 2 weeks with automatic token refresh.
+
+## Architecture
+
+### Token Types
+
+1. **Access Token (JWT)**
+   - Lifetime: 24 hours
+   - Stored in: httpOnly cookie + localStorage
+   - Used for: API authentication
+   - Format: JWT with subject and libraryId claims
+
+2. **Refresh Token**
+   - Lifetime: 14 days (2 weeks)
+   - Stored in: httpOnly cookie + database
+   - Used for: Generating new access tokens
+   - Format: Secure random 256-bit token (Base64 encoded)
+
+### Token Flow
+
+1. **Login**
+   - User provides password
+   - Backend validates password
+   - Backend generates both access token and refresh token
+   - Both tokens sent as httpOnly cookies
+   - Access token also returned in response body for localStorage
+
+2. **API Request**
+   - Frontend sends access token via Authorization header and cookie
+   - Backend validates access token
+   - If valid: Request proceeds
+   - If expired: Frontend attempts token refresh
+
+3. **Token Refresh**
+   - Frontend detects 401/403 response
+   - Frontend automatically calls `/api/auth/refresh`
+   - Backend validates refresh token from cookie
+   - If valid: New access token generated and returned
+   - If invalid/expired: User redirected to login
+
+4. **Logout**
+   - Frontend calls `/api/auth/logout`
+   - Backend revokes refresh token in database
+   - Both cookies cleared
+   - User redirected to login page
+
+## Backend Implementation
+
+### New Files
+
+1. **`RefreshToken.java`** - Entity class
+   - Fields: id, token, expiresAt, createdAt, revokedAt, libraryId, userAgent, ipAddress
+   - Helper methods: isExpired(), isRevoked(), isValid()
+
+2. **`RefreshTokenRepository.java`** - Repository interface
+   - findByToken(String)
+   - deleteExpiredTokens(LocalDateTime)
+   - revokeAllByLibraryId(String, LocalDateTime)
+   - revokeAll(LocalDateTime)
+
+3. **`RefreshTokenService.java`** - Service class
+   - createRefreshToken(libraryId, userAgent, ipAddress)
+   - verifyRefreshToken(token)
+   - revokeToken(token)
+   - revokeAllByLibraryId(libraryId)
+   - cleanupExpiredTokens() - Scheduled daily at 3 AM
+
+### Modified Files
+
+1. **`JwtUtil.java`**
+   - Added `refreshExpiration` property (14 days)
+   - Added `generateRefreshToken()` method
+   - Added `getRefreshExpirationMs()` method
+
+2. **`AuthController.java`**
+   - Updated `/login` endpoint to create and return refresh token
+   - Added `/refresh` endpoint to handle token refresh
+   - Updated `/logout` endpoint to revoke refresh token
+   - Added helper methods: `getRefreshTokenFromCookies()`, `getClientIpAddress()`
+
+3. **`SecurityConfig.java`**
+   - Added `/api/auth/refresh` to public endpoints
+
+4. **`application.yml`**
+   - Added `storycove.jwt.refresh-expiration: 1209600000` (14 days)
+
+## Frontend Implementation
+
+### Modified Files
+
+1. **`api.ts`**
+   - Added automatic token refresh logic in response interceptor
+   - Added request queuing during token refresh
+   - Prevents multiple simultaneous refresh attempts
+   - Automatically retries failed requests after refresh
+
+### Token Refresh Logic
+
+```typescript
+// On 401/403 response:
+1. Check if already retrying -> if yes, queue request
+2. Check if refresh/login endpoint -> if yes, logout
+3. Attempt token refresh via /api/auth/refresh
+4. If successful:
+   - Update localStorage with new token
+   - Retry original request
+   - Process queued requests
+5. If failed:
+   - Clear token
+   - Redirect to login
+   - Reject queued requests
+```
+
+## Security Features
+
+1. **httpOnly Cookies**: Prevents XSS attacks
+2. **Token Revocation**: Refresh tokens can be revoked
+3. **Database Storage**: Refresh tokens stored server-side
+4. **Expiration Tracking**: Tokens have strict expiration dates
+5. **IP & User Agent Tracking**: Stored for security auditing
+6. **Library Isolation**: Tokens scoped to specific library
+
+## Database Schema
+
+```sql
+CREATE TABLE refresh_tokens (
+    id UUID PRIMARY KEY,
+    token VARCHAR(255) UNIQUE NOT NULL,
+    expires_at TIMESTAMP NOT NULL,
+    created_at TIMESTAMP NOT NULL,
+    revoked_at TIMESTAMP,
+    library_id VARCHAR(255),
+    user_agent VARCHAR(255) NOT NULL,
+    ip_address VARCHAR(255) NOT NULL
+);
+
+CREATE INDEX idx_refresh_token ON refresh_tokens(token);
+CREATE INDEX idx_expires_at ON refresh_tokens(expires_at);
+```
+
+## Configuration
+
+### Backend (`application.yml`)
+
+```yaml
+storycove:
+  jwt:
+    expiration: 86400000        # 24 hours (access token)
+    refresh-expiration: 1209600000  # 14 days (refresh token)
+```
+
+### Environment Variables
+
+No new environment variables required. Existing `JWT_SECRET` is used.
+
+## Testing
+
+Comprehensive test suite in `RefreshTokenServiceTest.java`:
+- Token creation
+- Token validation
+- Expired token handling
+- Revoked token handling
+- Token revocation
+- Cleanup operations
+
+Run tests:
+```bash
+cd backend
+mvn test -Dtest=RefreshTokenServiceTest
+```
+
+## Maintenance
+
+### Automated Cleanup
+
+Expired tokens are automatically cleaned up daily at 3 AM via scheduled task in `RefreshTokenService.cleanupExpiredTokens()`.
+
+### Manual Revocation
+
+```java
+// Revoke all tokens for a library
+refreshTokenService.revokeAllByLibraryId("library-id");
+
+// Revoke all tokens (logout all users)
+refreshTokenService.revokeAll();
+```
+
+## User Experience
+
+1. **Seamless Authentication**: Users stay logged in for 2 weeks
+2. **Automatic Refresh**: Token refresh happens transparently
+3. **No Interruptions**: API calls succeed even when access token expires
+4. **Backend Restart**: Users must re-login (JWT secret rotates on startup)
+5. **Cross-Device Library Switching**: Automatic library switching when using different devices with different libraries
+
+## Cross-Device Library Switching
+
+### Feature Overview
+
+The system automatically detects and switches libraries when you use different devices authenticated to different libraries. This ensures you always see the correct library's data.
+
+### How It Works
+
+**Scenario 1: Active Access Token (within 24 hours)**
+1. Request comes in with valid JWT access token
+2. `JwtAuthenticationFilter` extracts `libraryId` from token
+3. Compares with `currentLibraryId` in backend
+4. **If different**: Automatically switches to token's library
+5. **If same**: Early return (no overhead, just string comparison)
+6. Request proceeds with correct library
+
+**Scenario 2: Token Refresh (after 24 hours)**
+1. Access token expired, refresh token still valid
+2. `/api/auth/refresh` endpoint validates refresh token
+3. Extracts `libraryId` from refresh token
+4. Compares with `currentLibraryId` in backend
+5. **If different**: Automatically switches to token's library
+6. **If same**: Early return (no overhead)
+7. Generates new access token with correct `libraryId`
+
+**Scenario 3: After Backend Restart**
+1. `currentLibraryId` is null (no active library)
+2. First request with any token automatically switches to that token's library
+3. Subsequent requests use early return optimization
+
+### Performance
+
+**When libraries match** (most common case):
+- Simple string comparison: `libraryId.equals(currentLibraryId)`
+- Immediate return - zero overhead
+- No datasource changes, no reindexing
+
+**When libraries differ** (switching devices):
+- Synchronized library switch
+- Datasource routing updated instantly
+- Solr reindex runs asynchronously (doesn't block request)
+- Takes 2-3 seconds in background
+
+### Edge Cases
+
+**Multi-device simultaneous use:**
+- If two devices with different libraries are used simultaneously
+- Last request "wins" and switches backend to its library
+- Not recommended but handled gracefully
+- Each device corrects itself on next request
+
+**Library doesn't exist:**
+- If token contains invalid `libraryId`
+- Library switch fails with error
+- Request is rejected with 500 error
+- User must re-login with valid credentials
+
+## Future Enhancements
+
+Potential improvements:
+1. Persistent JWT secret (survive backend restarts)
+2. Sliding refresh token expiration (extend on use)
+3. Multiple device management (view/revoke sessions)
+4. Configurable token lifetimes via environment variables
+5. Token rotation (new refresh token on each use)
+6. Thread-local library context for true stateless operation
+
+## Summary
+
+The refresh token implementation provides a robust, secure authentication system that balances user convenience (2-week sessions) with security (short-lived access tokens, automatic refresh). The implementation follows industry best practices and provides a solid foundation for future enhancements.

+# Solr Library Separation Migration Guide
+
+This guide explains how to migrate existing StoryCove deployments to support proper library separation in Solr search.
+
+## What Changed
+
+The Solr service has been enhanced to support multi-tenant library separation by:
+- Adding a `libraryId` field to all Solr documents
+- Filtering all search queries by the current library context
+- Ensuring complete data isolation between libraries
+
+## Migration Options
+
+### Option 1: Docker Volume Reset (Recommended for Docker)
+
+**Best for**: Development, staging, and Docker-based deployments where data loss is acceptable.
+
+```bash
+# Stop the application
+docker-compose down
+
+# Remove only the Solr data volume (preserves database and images)
+docker volume rm storycove_solr_data
+
+# Restart - Solr will recreate cores with new schema
+docker-compose up -d
+
+# Wait for services to start, then trigger reindex via admin panel
+```
+
+**Pros**: Clean, simple, guaranteed to work
+**Cons**: Requires downtime, loses existing search index
+
+### Option 2: Schema API Migration (Production Safe)
+
+**Best for**: Production environments where you need to preserve uptime.
+
+**Method A: Automatic (Recommended)**
+```bash
+# Single endpoint that adds field and migrates data
+curl -X POST "http://your-app-host/api/admin/search/solr/migrate-library-schema" \
+  -H "Authorization: Bearer YOUR_JWT_TOKEN"
+```
+
+**Method B: Manual Steps**
+```bash
+# Step 1: Add libraryId field via app API
+curl -X POST "http://your-app-host/api/admin/search/solr/add-library-field" \
+  -H "Authorization: Bearer YOUR_JWT_TOKEN"
+
+# Step 2: Run migration
+curl -X POST "http://your-app-host/api/admin/search/solr/migrate-library-schema" \
+  -H "Authorization: Bearer YOUR_JWT_TOKEN"
+```
+
+**Method C: Direct Solr API (if app API fails)**
+```bash
+# Add libraryId field to stories core
+curl -X POST "http://your-solr-host:8983/solr/storycove_stories/schema" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "add-field": {
+      "name": "libraryId",
+      "type": "string",
+      "indexed": true,
+      "stored": true,
+      "required": false
+    }
+  }'
+
+# Add libraryId field to authors core
+curl -X POST "http://your-solr-host:8983/solr/storycove_authors/schema" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "add-field": {
+      "name": "libraryId",
+      "type": "string",
+      "indexed": true,
+      "stored": true,
+      "required": false
+    }
+  }'
+
+# Then run the migration
+curl -X POST "http://your-app-host/api/admin/search/solr/migrate-library-schema" \
+  -H "Authorization: Bearer YOUR_JWT_TOKEN"
+```
+
+**Pros**: No downtime, preserves service availability, automatic field addition
+**Cons**: Requires API access
+
+### Option 3: Application-Level Migration (Recommended for Production)
+
+**Best for**: Production environments with proper admin access.
+
+1. **Deploy the code changes** to your environment
+2. **Access the admin panel** of your application
+3. **Navigate to search settings**
+4. **Use the "Migrate Library Schema" button** or API endpoint:
+   ```
+   POST /api/admin/search/solr/migrate-library-schema
+   ```
+
+**Pros**: User-friendly, handles all complexity internally
+**Cons**: Requires admin access to application
+
+## Step-by-Step Migration Process
+
+### For Docker Deployments
+
+1. **Backup your data** (optional but recommended):
+   ```bash
+   # Backup database
+   docker-compose exec postgres pg_dump -U storycove storycove > backup.sql
+   ```
+
+2. **Pull the latest code** with library separation fixes
+
+3. **Choose migration approach**:
+   - **Quick & Clean**: Use Option 1 (volume reset)
+   - **Production**: Use Option 2 or 3
+
+4. **Verify migration**:
+   - Log in with different library passwords
+   - Perform searches to confirm isolation
+   - Check that new content gets indexed with library IDs
+
+### For Kubernetes/Production Deployments
+
+1. **Update your deployment** with the new container images
+
+2. **Add the libraryId field** to Solr schema using Option 2
+
+3. **Use the migration endpoint** (Option 3):
+   ```bash
+   kubectl exec -it deployment/storycove-backend -- \
+     curl -X POST http://localhost:8080/api/admin/search/solr/migrate-library-schema
+   ```
+
+4. **Monitor logs** for successful migration
+
+## Verification Steps
+
+After migration, verify that library separation is working:
+
+1. **Test with multiple libraries**:
+   - Log in with Library A password
+   - Add/search content
+   - Log in with Library B password
+   - Confirm Library A content is not visible
+
+2. **Check Solr directly** (if accessible):
+   ```bash
+   # Should show documents with libraryId field
+   curl "http://solr:8983/solr/storycove_stories/select?q=*:*&fl=id,title,libraryId&rows=5"
+   ```
+
+3. **Monitor application logs** for any library separation errors
+
+## Troubleshooting
+
+### "unknown field 'libraryId'" Error
+
+**Problem**: `ERROR: [doc=xxx] unknown field 'libraryId'`
+
+**Cause**: The Solr schema doesn't have the libraryId field yet.
+
+**Solutions**:
+
+1. **Use the automated migration** (adds field automatically):
+   ```bash
+   curl -X POST "http://your-app/api/admin/search/solr/migrate-library-schema"
+   ```
+
+2. **Add field manually first**:
+   ```bash
+   # Add field via app API
+   curl -X POST "http://your-app/api/admin/search/solr/add-library-field"
+
+   # Then run migration
+   curl -X POST "http://your-app/api/admin/search/solr/migrate-library-schema"
+   ```
+
+3. **Direct Solr API** (if app API fails):
+   ```bash
+   # Add to both cores
+   curl -X POST "http://solr:8983/solr/storycove_stories/schema" \
+     -H "Content-Type: application/json" \
+     -d '{"add-field":{"name":"libraryId","type":"string","indexed":true,"stored":true}}'
+
+   curl -X POST "http://solr:8983/solr/storycove_authors/schema" \
+     -H "Content-Type: application/json" \
+     -d '{"add-field":{"name":"libraryId","type":"string","indexed":true,"stored":true}}'
+   ```
+
+4. **For development**: Use Option 1 (volume reset) for clean restart
+
+### Migration Endpoint Returns Error
+
+Common causes:
+- Solr is not available (check connectivity)
+- No active library context (ensure user is authenticated)
+- Insufficient permissions (check JWT token/authentication)
+
+### Search Results Still Mixed
+
+This indicates incomplete migration:
+- Clear all Solr data and reindex completely
+- Verify that all documents have libraryId field
+- Check that search queries include library filters
+
+## Environment-Specific Notes
+
+### Development
+- Use Option 1 (volume reset) for simplicity
+- Data loss is acceptable in dev environments
+
+### Staging
+- Use Option 2 or 3 to test production migration procedures
+- Verify migration process before applying to production
+
+### Production
+- **Always backup data first**
+- Use Option 2 (Schema API) or Option 3 (Admin endpoint)
+- Plan for brief performance impact during reindexing
+- Monitor system resources during bulk reindexing
+
+## Performance Considerations
+
+- **Reindexing time**: Depends on data size (typically 1000 docs/second)
+- **Memory usage**: May increase during bulk indexing
+- **Search performance**: Minimal impact from library filtering
+- **Storage**: Slight increase due to libraryId field
+
+## Rollback Plan
+
+If issues occur:
+
+1. **Immediate**: Restart Solr to previous state (if using Option 1)
+2. **Schema revert**: Remove libraryId field via Schema API
+3. **Code rollback**: Deploy previous version without library separation
+4. **Data restore**: Restore from backup if necessary
+
+This migration enables proper multi-tenant isolation while maintaining search performance and functionality.

-
-## ✅ Best Practices Implemented
-
-### 🔒 **Security**
-- **Environment-Aware SSL Configuration**
-  - Production: Full certificate validation with custom truststore support
-  - Development: Optional certificate validation for local development
-- **Proper Authentication**: Basic auth with secure credential management
-- **Connection Security**: TLS 1.3 support with hostname verification
-
-### 🏗️ **Configuration Management**
-- **Externalized Configuration**: JSON/YAML files instead of hardcoded values
-- **Environment-Specific Settings**: Different configs for dev/staging/prod
-- **Type-Safe Properties**: Strongly-typed configuration classes
-- **Validation**: Configuration validation at startup
-
-### 📈 **Scalability & Performance**
-- **Connection Pooling**: Configurable connection pool with timeout management
-- **Environment-Aware Sharding**:
-  - Development: 1 shard, 0 replicas (single node)
-  - Production: 3 shards, 1 replica (high availability)
-- **Bulk Operations**: Optimized bulk indexing with configurable batch sizes
-- **Index Templates**: Automatic application of settings to new indexes
-
-### 🔄 **Index Lifecycle Management**
-- **Automated Index Rollover**: Based on size, document count, and age
-- **Hot-Warm-Cold Architecture**: Optimized storage costs
-- **Retention Policies**: Automatic cleanup of old data
-- **Force Merge**: Optimization in warm phase
-
-### 📊 **Monitoring & Observability**
-- **Health Checks**: Automatic cluster health monitoring
-- **Spring Boot Actuator**: Health endpoints for monitoring systems
-- **Metrics Collection**: Configurable performance metrics
-- **Slow Query Detection**: Configurable thresholds for query performance
-
-### 🛡️ **Error Handling & Resilience**
-- **Connection Retry Logic**: Automatic retry with backoff
-- **Circuit Breaker Pattern**: Fail-fast for unhealthy clusters
-- **Graceful Degradation**: Graceful handling when OpenSearch unavailable
-- **Detailed Error Logging**: Comprehensive error tracking
-
-## 🚀 Usage
-
-### Development Environment
-```yaml
-# application-development.yml
-storycove:
-  opensearch:
-    profile: development
-    security:
-      ssl-verification: false
-      trust-all-certificates: true
-    indices:
-      default-shards: 1
-      default-replicas: 0
-```
-
-### Production Environment
-```yaml
-# application-production.yml
-storycove:
-  opensearch:
-    profile: production
-    security:
-      ssl-verification: true
-      trust-all-certificates: false
-      truststore-path: /etc/ssl/opensearch-truststore.jks
-    indices:
-      default-shards: 3
-      default-replicas: 1
-```
-
-## 📋 Environment Variables
-
-### Required
-- `OPENSEARCH_PASSWORD`: Admin password for OpenSearch cluster
-
-### Optional (with sensible defaults)
-- `OPENSEARCH_HOST`: Cluster hostname (default: localhost)
-- `OPENSEARCH_PORT`: Cluster port (default: 9200)
-- `OPENSEARCH_USERNAME`: Admin username (default: admin)
-- `OPENSEARCH_SSL_VERIFICATION`: Enable SSL verification (default: false for dev)
-- `OPENSEARCH_MAX_CONN_TOTAL`: Max connections (default: 30 for dev, 200 for prod)
-
-## 🎯 Index Templates
-
-Index templates automatically apply configuration to new indexes:
-
-```json
-{
-  "index_patterns": ["stories_*"],
-  "template": {
-    "settings": {
-      "number_of_shards": "#{ENV_SPECIFIC}",
-      "analysis": {
-        "analyzer": {
-          "story_analyzer": {
-            "type": "standard",
-            "stopwords": "_english_"
-          }
-        }
-      }
-    }
-  }
-}
-```
-
-## 🔍 Health Monitoring
-
-Access health information:
-- **Application Health**: `/actuator/health`
-- **OpenSearch Specific**: `/actuator/health/opensearch`
-- **Detailed Metrics**: Available when `enable-metrics: true`
-
-## 🔄 Deployment Strategy
-
-Recommended deployment approach:
-
-1. **Development**: Test OpenSearch configuration locally
-2. **Staging**: Validate performance and accuracy in staging environment
-3. **Production**: Deploy with proper monitoring and backup procedures
-
-## 🛠️ Troubleshooting
-
-### Common Issues
-
-1. **SSL Certificate Errors**
-   - Development: Set `trust-all-certificates: true`
-   - Production: Provide valid truststore path
-
-2. **Connection Timeouts**
-   - Increase `connection.timeout` values
-   - Check network connectivity and firewall rules
-
-3. **Index Creation Failures**
-   - Verify cluster health with `/actuator/health/opensearch`
-   - Check OpenSearch logs for detailed error messages
-
-4. **Performance Issues**
-   - Monitor slow queries with configurable thresholds
-   - Adjust bulk operation settings
-   - Review shard allocation and replica settings
-
-## 🔮 Future Enhancements
-
-- **Multi-Cluster Support**: Connect to multiple OpenSearch clusters
-- **Advanced Security**: Integration with OpenSearch Security plugin
-- **Custom Analyzers**: Domain-specific text analysis
-- **Index Aliases**: Zero-downtime index updates
-- **Machine Learning**: Integration with OpenSearch ML features
-
