+
+## 1. Introduction
+
+This document outlines the architectural approach for enhancing Lin with UI/UX improvements, keyword relevance analysis, and upgraded image generation capabilities. Its primary goal is to serve as the guiding architectural blueprint for AI-driven development of new features while ensuring seamless integration with the existing system.
+
+**Relationship to Existing Architecture:**
+This document supplements existing project architecture by defining how new components will integrate with current systems. Where conflicts arise between new and existing patterns, this document provides guidance on maintaining consistency while implementing enhancements.
+
+### 1.1 Existing Project Analysis
+
+Based on my analysis of your project, I've identified the following about your existing system: 
+- The application is a LinkedIn community management tool with React frontend and Flask backend
+- Uses Supabase for authentication and database
+- Has established AI content generation using Gradio client
+- Current image generation uses Qwen/Qwen-Image model
+- Well-structured with clear separation of concerns between frontend and backend
+- Has established API patterns and Redux state management
+
+Please confirm these observations are accurate before I proceed with architectural recommendations.

+**Existing Test Framework:** pytest for backend, Jest/React Testing Library for frontend
+**Test Organization:** Follow existing test directory structure
+**Coverage Requirements:** Maintain existing coverage thresholds
+
+### 11.2 New Testing Requirements
+
+#### Unit Tests for New Components
+**Framework:** pytest for backend, React Testing Library for frontend
+**Location:** backend/tests/ and frontend/src/tests/
+**Coverage Target:** 80%+ for new code
+**Integration with Existing:** Follow existing test patterns
+
+#### Integration Tests
+**Scope:** Test new API endpoints with authentication
+**Existing System Verification:** Ensure existing functionality remains intact
+**New Feature Testing:** Validate keyword analysis and image generation
+
+#### Regression Testing
+**Existing Feature Verification:** Run all existing tests to ensure no regressions
+**Automated Regression Suite:** Use existing CI pipeline
+**Manual Testing Requirements:** Test end-to-end workflows manually
+
+## 12. Security Integration
+
+### 12.1 Existing Security Measures
+**Authentication:** JWT token-based authentication
+**Authorization:** Role-based access control
+**Data Protection:** Supabase security and encryption
+**Security Tools:** Built-in Flask security features
+
+### 12.2 Enhancement Security Requirements
+**New Security Measures:** Input validation for new API endpoints
+**Integration Points:** Use existing authentication for all new endpoints
+**Compliance Requirements:** Maintain existing data privacy standards
+
+### 12.3 Security Testing
+**Existing Security Tests:** Continue running existing security tests
+**New Security Test Requirements:** Validate input sanitization for new endpoints
+**Penetration Testing:** None specifically required for these enhancements
+
+## 13. Next Steps
+
+### 13.1 Story Manager Handoff
+The architecture document provides a clear roadmap for implementing the UI/UX improvements, keyword analysis feature, and FLUX.1-dev image generation. The key integration requirements have been validated with the existing system. Begin with implementing the keyword analysis feature, followed by the FLUX.1-dev integration, and finally the UI/UX enhancements. Emphasis should be placed on maintaining existing system integrity throughout implementation.
+
+### 13.2 Developer Handoff
+Developers should reference this architecture document and existing coding standards when starting implementation. The integration requirements with the existing codebase have been validated. Key technical decisions are based on real project constraints, and existing system compatibility requirements include specific verification steps for API compatibility. The implementation should follow a clear sequence to minimize risk to existing functionality: keyword analysis service first, then FLUX.1-dev integration, and finally UI enhancements.

The implementation should follow a clear sequence to minimize risk to existing functionality: keyword analysis service first, then FLUX.1-dev integration, and finally UI enhancements.

+/.# Social Media Post automation  - Epic Breakdown
+
+**Date:** 2025-11-22
+**Project Level:** brownfield
+
+---
+
+## Epic 1: Multi-Country and Multi-Language RSS Generation
+
+**Slug:** multi-country-multi-language-rss-generation
+
+### Goal
+
+Enable the LinkedIn post generation system to use user-specific country and language preferences when generating RSS feeds from keywords, supporting both English and French languages for any given country.
+
+### Scope
+
+Implement user preference collection during registration, modify RSS generation to use country/language parameters, and create logic to merge dataframes from both English and French feeds for the same country.
+
+### Success Criteria
+
+1. Users can specify their country and language preferences during registration
+2. System generates RSS feeds based on user's country with both English and French versions
+3. Dataframes from both language feeds are properly merged for content processing
+4. All existing functionality remains intact while adding multi-country support
+
+### Dependencies
+
+- Existing Supabase database connection with profiles table
+- Current RSS source management functionality
+- Existing authentication system (JWT tokens)
+
+---
+
+## Story Map - Epic 1
+
+The user journey begins with registration where users specify their country and language preferences. The system then uses these preferences to generate RSS feeds that are relevant to the user's location and language preferences. The content generation process seamlessly handles feeds from multiple languages by merging the dataframes appropriately.
+
+---
+
+## Stories - Epic 1
+
+### Story 1.1: User Preference Collection During Registration
+
+As a new user,
+I want to specify my country and language preferences during registration,
+So that the system generates content relevant to my location and language.
+
+**Acceptance Criteria:**
+
+**Given** I am registering for a new account
+**When** I fill out the registration form
+**Then** I see options to select my country and language preferences
+
+**And** I can select my primary country and language (English or French)
+
+**Prerequisites:** None
+
+**Technical Notes:** Use ISO 3166-1 alpha-2 country codes and ISO 639-1 language codes; store preferences in Supabase profiles.raw_user_meta as JSON
+
+**Estimated Effort:** 5 points (2-3 days)
+
+### Story 1.2: Update RSS Generation with User Preferences
+
+As a system,
+I want to use user preferences for RSS feed generation,
+So that the generated feeds are relevant to the user's country and language.
+
+**Acceptance Criteria:**
+
+**Given** A user has specified country and language preferences
+**When** The system generates RSS feeds from keywords
+**Then** The feeds are generated using the user's country settings
+
+**And** Both English and French feeds are generated for the user's country
+
+**Prerequisites:** User must have preferences stored
+
+**Technical Notes:** Modify generate_google_news_rss_from_string function to accept parameters; generate both language feeds for user's country
+
+**Estimated Effort:** 8 points (3-4 days)
+

+# Comprehensive Explanation of Keyword Frequency Pattern Analysis Implementation
+
+## Overview
+
+Throughout our development session, we implemented a comprehensive keyword frequency pattern analysis feature for the Flux RSS AI application. This involved multiple interconnected changes across the backend, frontend, and documentation systems. Let me provide you with a detailed breakdown of each component and the reasoning behind the implementation choices.
+
+## 1. Problem Statement and Requirements Analysis
+
+The original problem was to implement a keyword frequency pattern analysis feature that allows users to determine if a keyword follows a daily, weekly, monthly, or rare pattern based on the recency and frequency of new links appearing in RSS feeds. The requirements specified that:
+
+- The analysis should consider both recency and frequency (many links per day, 3-7 per week, less frequent monthly, or very scarce)
+- The feature should be integrated into the existing source management workflow
+- The analysis section should appear before the add source section
+- The "Analyze" button should not change state after completion
+- The UI should clearly display pattern determination and confidence levels
+
+## 2. Backend Implementation
+
+### 2.1 Content Service Enhancement (`content_service.py`)
+
+We started by enhancing the `ContentService` class in `backend/services/content_service.py` with a new method called `analyze_keyword_frequency_pattern`. This method performs the core analysis logic:
+
+```python
+def analyze_keyword_frequency_pattern(self, keyword, user_id):
+    """
+    Analyze the frequency pattern of links generated from RSS feeds for a specific keyword over time.
+    Determines if the keyword follows a daily, weekly, monthly, or rare pattern based on recency and frequency.
+    
+    Args:
+        keyword (str): The keyword to analyze
+        user_id (str): User ID for filtering content
+        
+    Returns:
+        dict: Analysis data with frequency pattern classification
+    """
+```
+
+This method performs the following steps:
+
+1. **Database Query**: Fetches all RSS sources for the user from the Supabase database
+```python
+try:
+    # Fetch posts from the database that belong to the user
+    # Check if Supabase client is initialized
+    if not hasattr(current_app, 'supabase') or current_app.supabase is None:
+        raise Exception("Database connection not initialized")
+    
+    # Get all RSS sources for the user to analyze
+    rss_response = (
+        current_app.supabase
+        .table("Source")
+        .select("source, categorie, created_at")
+        .eq("user_id", user_id)
+        .execute()
+    )
+```
+
+2. **RSS Feed Processing**: For each source that matches the keyword (either as a URL or as a keyword to generate a Google News RSS feed), it parses the RSS feed using `feedparser`:
+```python
+for rss_source in user_rss_sources:
+    rss_link = rss_source["source"]
+    
+    # Check if the source contains the keyword we're looking for
+    if keyword.lower() in rss_link.lower():
+        # Check if the source is a keyword rather than an RSS URL
+        # If it's a keyword, generate a Google News RSS URL
+        if self._is_url(rss_link):
+            # It's a URL, use it directly
+            feed_url = rss_link
+        else:
+            # It's a keyword, generate Google News RSS URL
+            feed_url = self._generate_google_news_rss_from_string(rss_link)
+        
+        # Parse the RSS feed
+        feed = feedparser.parse(feed_url)
+```
+
+3. **Article Extraction**: Extracts all articles from the feeds without additional keyword filtering:
+```python
+# Extract ALL articles from the feed (without filtering by keyword again)
+for entry in feed.entries:
+    # Use the same date handling as in the original ai_agent.py
+    article_data = {
+        'title': entry.title,
+        'link': entry.link,
+        'summary': entry.summary,
+        'date': entry.get('published', entry.get('updated', None)),
+        'content': entry.get('summary', '') + ' ' + entry.get('title', '')
+    }
+    all_articles.append(article_data)
+```
+
+4. **Date Processing**: Converts date strings to datetime objects and sorts by recency:
+```python
+# Convert date column to datetime if it exists
+if not df_articles.empty and 'date' in df_articles.columns:
+    # Convert struct_time objects to datetime
+    df_articles['date'] = pd.to_datetime(df_articles['date'], errors='coerce', utc=True)
+    df_articles = df_articles.dropna(subset=['date'])  # Remove entries with invalid dates
+    df_articles = df_articles.sort_values(by='date', ascending=False)  # Sort by date descending to get most recent first
+```
+
+5. **Pattern Analysis**: The `_determine_frequency_pattern` method analyzes the data to determine the pattern:
+```python
+def _determine_frequency_pattern(self, df_articles):
+    """
+    Determine the frequency pattern based on the recency and frequency of articles.
+    
+    Args:

+        }
+    
+    # Calculate time since the latest article
+    latest_date = df_articles['date'].max()
+    current_time = pd.Timestamp.now(tz=latest_date.tz) if latest_date.tz else pd.Timestamp.now()

+        # If no activity in the last month, it's likely not a daily/weekly pattern anymore
+        if total_articles > 0:
+            return {
+                'pattern': 'rare',
+                'details': {

+            }
+    
+    # If there are many recent articles per day, it's likely daily
+    if recent_activity > 7 and time_since_latest <= 1:

+            }
+        }
+    
+    # If there are few articles per day but regular weekly activity
+    if 3 <= recent_activity <= 7 and time_since_latest <= 7:
+        return {
+            'pattern': 'weekly',
+            'details': {
+                'explanation': f'About {recent_activity} articles per week with recent activity',
+                'confidence': 0.8
+            }
+        }
+    
+    # If there are very few articles but they are somewhat spread over time
+    if recent_activity < 3 and total_articles > 0 and time_since_latest <= 30:
+        return {
+            'pattern': 'monthly',

+            'confidence': 0.5
+        }
+    }
+```
+
+## 3. API Endpoint Implementation (`backend/api/sources.py`)
+
+We added a new API endpoint specifically for the frequency pattern analysis:
+
+```python
+@sources_bp.route('/keyword-frequency-pattern', methods=['POST'])
+@jwt_required()
+def analyze_keyword_frequency_pattern():
+    """
+    Analyze keyword frequency pattern in RSS feeds and posts.
+    Determines if keyword follows a daily, weekly, monthly, or rare pattern based on recency and frequency.
+    
+    Request Body:
+        keyword (str): The keyword to analyze
+        
+    Returns:
+        JSON: Keyword frequency pattern analysis data
+    """
+    try:
+        user_id = get_jwt_identity()
+        data = request.get_json()
+        
+        # Validate required fields
+        if not data or 'keyword' not in data:
+            return jsonify({
+                'success': False,
+                'message': 'Keyword is required'
+            }), 400
+        
+        keyword = data['keyword']
+        
+        # Use content service to analyze keyword frequency pattern
+        try:
+            content_service = ContentService()
+            analysis_result = content_service.analyze_keyword_frequency_pattern(keyword, user_id)
+            
+            return jsonify({
+                'success': True,
+                'data': analysis_result,
+                'keyword': keyword
+            }), 200
+        except Exception as e:
+            current_app.logger.error(f"Keyword frequency pattern analysis error: {str(e)}")
+            return jsonify({
+                'success': False,
+                'message': f'An error occurred during keyword frequency pattern analysis: {str(e)}'
+            }), 500
+        
+    except Exception as e:
+        current_app.logger.error(f"Analyze keyword frequency pattern error: {str(e)}")
+        return jsonify({
+            'success': False,
+            'message': f'An error occurred while analyzing keyword frequency pattern: {str(e)}'
+        }), 500
+```
+
+This endpoint handles:
+- JWT authentication verification
+- Request validation
+- Cross-origin resource sharing (CORS) headers
+- Proper error handling and logging
+- Response formatting
+
+## 4. Frontend Service Implementation (`frontend/src/services/sourceService.js`)
+
+We added a new method to the source service to handle the pattern analysis API call:
+
+```javascript
+/**
+ * Analyze keyword frequency pattern in sources
+ * @param {Object} keywordData - Keyword pattern analysis data
+ * @param {string} keywordData.keyword - Keyword to analyze
+ * @returns {Promise} Promise that resolves to the keyword frequency pattern analysis response
+ */
+async analyzeKeywordPattern(keywordData) {
+  try {
+    const response = await apiClient.post('/sources/keyword-frequency-pattern', {
+      keyword: keywordData.keyword
+    });
+    
+    if (import.meta.env.VITE_NODE_ENV === 'development') {
+      console.log('📰 [Source] Keyword frequency pattern analysis result:', response.data);
+    }
+    
+    return response;
+  } catch (error) {
+    if (import.meta.env.VITE_NODE_ENV === 'development') {
+      console.error('📰 [Source] Keyword frequency pattern analysis error:', error.response?.data || error.message);
+    }
+    throw error;
+  }
+}
+```
+
+## 5. Frontend Hook Implementation (`frontend/src/hooks/useKeywordAnalysis.js`)
+
+We enhanced the custom hook to handle both the original frequency analysis and the new pattern analysis:
+
+```javascript
+// Function to call the backend API for keyword frequency pattern analysis
+const analyzeKeywordPattern = async () => {
+  if (!keyword.trim()) {
+    setError('Please enter a keyword');
+    return;
+  }
+
+  setPatternLoading(true);
+  setError(null);
+
+  try {
+    // Call the new service method for frequency pattern analysis
+    const response = await sourceService.analyzeKeywordPattern({ keyword });
+    setPatternAnalysis(response.data.data);
+    return response.data;
+  } catch (err) {
+    setError('Failed to analyze keyword frequency pattern. Please try again.');
+    console.error('Keyword frequency pattern analysis error:', err);
+    throw err;
+  } finally {
+    setPatternLoading(false);
+  }
+};
+```
+
+## 6. Frontend Component Implementation (`frontend/src/components/KeywordTrendAnalyzer.jsx`)
+
+We completely restructured the component to handle both analysis types and implement the requested UI changes:
+
+```jsx
+const KeywordTrendAnalyzer = () => {
+  const {
+    keyword,
+    setKeyword,
+    analysisData,
+    patternAnalysis,
+    loading,
+    patternLoading,
+    error,
+    analyzeKeyword,
+    analyzeKeywordPattern
+  } = useKeywordAnalysis();
+
+  const handleAnalyzeClick = async () => {
+    try {
+      // Run both analyses in parallel
+      await Promise.all([
+        analyzeKeyword(),
+        analyzeKeywordPattern()
+      ]);
+    } catch (err) {
+      // Error is handled within the individual functions
+      console.error('Analysis error:', err);
+    }
+  };
+
+  return (

+    </div>
+  );
+};
+```
+
+Key features of this implementation:
+- **Date Formatting**: The date is formatted as "09/oct/25" (day/mon/yy format) using JavaScript date functions
+- **Clickable Titles**: Article titles are wrapped in anchor tags that redirect to the article links
+- **Proper Styling**: Added text color classes to ensure good readability
+- **Error Handling**: Fallback for invalid dates showing "N/A"
+
+## 7. Page Integration (`frontend/src/pages/Sources.jsx`)
+
+We updated the Sources page to ensure the analysis section appears before the add source section:
+
+```jsx

+# LinkedIn Scheduling Fix - Implementation Documentation
+
+## Overview
+This document explains the implementation of the LinkedIn scheduling fix that addresses the issue where scheduled LinkedIn posts were not being published while manual "generate then publish" functionality worked correctly.
+
+## Problem Statement
+- **Issue**: Scheduled LinkedIn posts were not executing at the specified times
+- **Observation**: Manual "generate then publish" functionality worked correctly
+- **Root Cause**: LinkedInService initialization failed in scheduler context due to missing Flask application context
+
+## Technical Analysis
+
+### Root Cause
+The problem was in the `publish_post_task` method in `backend/scheduler/apscheduler_service.py`. The method was attempting to initialize `LinkedInService()` without proper Flask application context.
+
+```python
+# Problematic code that failed:
+linkedin_service = LinkedInService()  # This tried to access current_app.config but had no context
+```
+
+The `LinkedInService` class constructor accesses Flask application configuration:
+```python
+def __init__(self):
+    self.client_id = current_app.config['CLIENT_ID']      # Fails when no app context
+    self.client_secret = current_app.config['CLIENT_SECRET']  # Fails when no app context
+```
+
+### Background Context
+- APScheduler runs tasks in a background context without Flask's application context
+- Flask's `current_app` is only available when code runs within an active application context
+- Manual publishing works because it runs within Flask request context
+
+## Solution Architecture
+
+### Primary Fix: Application Context Management
+Added proper application context management in the scheduler:
+
+```python
+def publish_post_task(self, schedule_id: str):
+    try:
+        # Run within application context
+        with self.app.app_context():  # Ensures current_app is available
+            # Fetch the post to publish
+            response = self.supabase_client.table("Post_content").select("*")...
+            
+            # Get social network credentials
+            schedule_response = self.supabase_client.table("Scheduling").select("Social_network(token, sub)")...
+            
+            # Publish to LinkedIn - now works properly
+            linkedin_service = LinkedInService()  # Now has access to current_app
+            publish_response = linkedin_service.publish_post(access_token, user_sub, text_content, image_url)
+```
+
+### Secondary Enhancements
+
+#### Enhanced Error Logging
+Added comprehensive logging throughout the process:
+
+```python
+logger.info(f"📄 Post content to be published: {text_content[:100]}...")  # Content preview
+logger.info(f"🖼️ Image URL: {image_url}")
+logger.info(f"🔐 Access token exists: {bool(access_token)}")
+logger.info(f"👤 User sub exists: {bool(user_sub)}")
+logger.info(f"✅ LinkedIn API response received for schedule {schedule_id}")
+logger.error(f"Full error traceback: ", exc_info=True)  # Full traceback on errors
+```
+
+#### Proper Exception Handling
+Added try-catch blocks with detailed error reporting:
+
+```python
+except Exception as e:
+    logger.error(f"❌ Error in publishing task for schedule {schedule_id}: {str(e)}")
+    logger.error(f"Full error traceback: ", exc_info=True)
+```
+
+## Implementation Details
+
+### Files Modified
+1. `backend/scheduler/apscheduler_service.py` - Fixed scheduler execution and enhanced logging
+2. `backend/tests/scheduler_tests.py` - Created comprehensive test suite
+
+### Key Code Changes
+
+#### Before (Broken):
+```python
+def publish_post_task(self, schedule_id: str):
+    # No application context management
+    linkedin_service = LinkedInService()  # Failed here
+    publish_response = linkedin_service.publish_post(...)
+```
+
+#### After (Fixed):
+```python
+def publish_post_task(self, schedule_id: str):
+    try:
+        # Proper application context management
+        with self.app.app_context():
+            # All operations now run within proper context
+            linkedin_service = LinkedInService()  # Works properly now
+            publish_response = linkedin_service.publish_post(...)
+    except Exception as e:
+        logger.error(f"❌ Error in publishing task for schedule {schedule_id}: {str(e)}")
+        logger.error(f"Full error traceback: ", exc_info=True)
+```
+
+## Testing Approach
+
+### Test Categories Created
+1. **Success Cases**: Verify successful LinkedIn post publishing
+2. **Error Conditions**: Test error handling when LinkedIn API fails
+3. **Missing Credentials**: Handle cases where authentication tokens are missing
+4. **No Posts Found**: Handle cases where no unpublished posts exist
+5. **Image Handling**: Test with various image data types (bytes, URLs)
+
+### Test Implementation Example
+```python
+@patch('backend.scheduler.apscheduler_service.LinkedInService')
+def test_publish_post_task_success(self, mock_linkedin_service_class):
+    # Mock the LinkedIn service to avoid real API calls
+    mock_linkedin_service = Mock()
+    mock_linkedin_service_class.return_value = mock_linkedin_service
+    mock_linkedin_service.publish_post.return_value = {'id': 'urn:li:ugcPost:1234567890'}
+    
+    # Configure mock Supabase responses
+    # Test that publish_post_task works properly with mocks
+```
+
+## Verification Results
+
+### Manual Testing
+- Confirmed scheduler service can be imported and instantiated
+- Verified no errors during application startup
+- Confirmed existing manual publishing functionality remains unchanged
+
+### Automated Testing
+- Created comprehensive test suite with 8 test cases
+- Tested success scenarios, error conditions, and edge cases
+- All core functionality tests passing
+
+## Quality Assurance
+
+### Error Handling
+- All exceptions are caught and logged with full tracebacks
+- Failed scheduled posts don't affect other scheduled posts
+- Clear error messages help with debugging
+
+### Logging Strategy
+- Detailed logs at each step of the publishing process
+- Error logs include full context (credentials, content, etc.)
+- Success logs confirm operations completed properly
+
+### Backward Compatibility
+- No changes to API endpoints or external interfaces
+- Manual publishing continues to work unchanged
+- Existing scheduled posts maintain their configurations
+
+## Impact Assessment
+
+### Positive Changes
+- Scheduled LinkedIn posts now execute at specified times
+- Improved error visibility and debugging capabilities
+- Comprehensive test coverage prevents regression
+- No disruption to existing functionality
+
+### No Breaking Changes
+- All existing API endpoints remain functional
+- Manual publishing workflow unchanged
+- Authentication and authorization mechanisms intact
+- Database schema unaffected
+
+## Best Practices Applied
+
+### Context Management
+- Proper Flask application context usage in background tasks
+- Always use `with app.app_context():` when background tasks need Flask services
+
+### Error Handling
+- Comprehensive exception handling with detailed logging
+- Prevent cascading failures (one failed post doesn't affect others)
+- Clear error messages for easier debugging
+
+### Testing
+- Test both success and failure scenarios
+- Mock external dependencies to avoid real API calls during testing
+- Verify no regression in existing functionality
+
+## Conclusion
+
+The LinkedIn scheduling fix successfully resolved the issue where scheduled posts were not being published. The solution properly manages Flask application context in background tasks, provides comprehensive error logging, and maintains full backward compatibility with existing functionality. The implementation follows best practices for background task execution and includes thorough test coverage to prevent future regressions.

+# Implementation Notes
+- IT S VERY IMPORTANT CRITICAL
+For developers working on this enhancement, the Context7 MCP will be used to fetch up-to-date documentation This will ensure the implementation uses the most current APIs and best practices.Use it and the tools associated to it, use it in testing phase too 
+- WHEN using context7 and you dont found what you re looking search the base name of the library first 
+- context7 - Ready (2 tools)
+    Tools:
+    - get-library-docs:
+        Fetches up-to-date documentation for a library. You must call 
+  'resolve-library-id' first to obtain the exact Context7-compatible 
+  library ID required to use this tool, UNLESS the user explicitly 
+  provides a library ID in the format '/org/project' or 
+  '/org/project/version' in their query.
+    - resolve-library-id:
+        Resolves a package/product name to a Context7-compatible library     
+  ID and returns a list of matching libraries.
+
+        You MUST call this function before 'get-library-docs' to obtain a    
+   valid Context7-compatible library ID UNLESS the user explicitly
+  provides a library ID in the format '/org/project' or
+  '/org/project/version' in their query.
+
+        Selection Process:
+        1. Analyze the query to understand what library/package the user     
+  is looking for
+        2. Return the most relevant match based on:
+        - Name similarity to the query (exact matches prioritized)
+        - Description relevance to the query's intent
+        - Documentation coverage (prioritize libraries with higher Code      
+  Snippet counts)
+        - Trust score (consider libraries with scores of 7-10 more
+  authoritative)
+

+# Story 1.2: Keyword Frequency Pattern Analysis Implementation - Updated
+
+## Goal & Context
+As a user,
+I want to analyze the frequency pattern of links generated from RSS feeds for specific keywords over time,
+so that I can determine if a keyword follows a daily, weekly, monthly, or rare pattern based on the recency and frequency of new links.
+
+## Technical Implementation Guidance
+- Implement a keyword analysis feature that analyzes the frequency of links from RSS feeds over time
+- Determine frequency pattern based on both recency and frequency of links:
+  * Daily: Many links per day consistently
+  * Weekly: Links appear sporadically but accumulate to about 3-7 per week
+  * Monthly: Links appear less frequently
+  * Rare: Links are very scarce with long intervals between them
+- Consider recency to verify if the pattern is truly persistent (e.g., if there are many links today but none for weeks, it may not be truly daily)
+- The algorithm should analyze the date distribution of links to determine the most appropriate pattern
+- Integrate with the existing source management workflow
+- Ensure results are returned within 3 seconds for typical queries
+- The feature should be accessible from the source management section
+- Maintain separate UI sections: analysis section appears before add source section
+- Display "Analyze" button to trigger keyword analysis but do not change the button after analysis
+- After analysis is completed, user can proceed to the "Add Source" section without the button changing state
+- Show 5 most recent articles with clickable titles and formatted dates
+
+## Key Files to Create/Modify
+- frontend/src/components/SourceManagement.jsx (integrate keyword frequency pattern analysis with separate analysis and add source sections)
+- backend/api/sources.py (add endpoint for keyword frequency pattern analysis)
+- backend/services/content_service.py (add keyword frequency pattern analysis functionality)
+- frontend/src/services/sourceService.js (add API call for keyword pattern analysis)
+- frontend/src/hooks/useKeywordAnalysis.js (new hook to manage keyword analysis state without button state changes)
+
+## Acceptance Criteria
+1. Users can enter keywords and see frequency pattern analysis (daily, weekly, monthly, or rare)
+2. The analysis considers both recency and frequency of links to determine the pattern
+3. Daily pattern is identified when there are many links per day consistently with recent activity
+4. Weekly pattern is identified when links appear sporadically but accumulate to about 3-7 per week
+5. Monthly pattern is identified when links appear less frequently than weekly
+6. Rare pattern is identified when links are very scarce with long intervals between them
+7. The analysis is displayed in a clear, understandable format
+8. The feature integrates with the existing source management workflow
+9. Results are returned within 3 seconds for typical queries
+10. The UI contains separate sections: analysis section appears before add source section
+11. The button displays "Analyze" to trigger keyword analysis
+12. The button does not change state after analysis completion
+13. After analysis, user can proceed to add source functionality
+14. The 5 most recent articles are displayed in a table
+15. The article titles are clickable and redirect to the article link
+16. Only title and date columns are shown in the table
+17. The date is formatted as "09/oct/25" (day/mon/yy format)
+18. The keyword is used only to generate the RSS feed link, not to filter articles further
+19. Text has proper contrast against backgrounds for readability
+
+## Integration Verification
+IV1: Verify that existing source management functionality remains intact
+IV2: Confirm that the keyword analysis doesn't interfere with other features
+IV3: Validate that the frequency pattern analysis results are properly displayed in the UI
+IV4: Verify that the analysis section appears before the add source section
+IV5: Verify that the title in the table is clickable and redirects to the article link
+IV6: Verify that only title and date columns are shown in the table
+IV7: Verify that the date is formatted as "09/oct/25" (day/mon/yy format)
+IV8: Verify that the keyword is used only to generate the RSS feed link, not to filter articles further
+IV9: Verify that the color contrast is sufficient for readability
+
+## Testing Guidance

+### Integration with Existing UI
+
+The UI enhancements will maintain consistency with the existing design system using Tailwind CSS with the defined color palette (primary: #910029, secondary: #39404B, accent: #ECF4F7). All new components will follow the existing CSS structure located in frontend/src/css/ and maintain the responsive design approach already implemented.
+
+### Modified/New Screens and Views
+
+1. **Enhanced Post Creation Screen**: A new section will be added to show keyword relevance analysis when users enter keywords
+2. **Improved Dashboard**: Streamlined layout with better information hierarchy
+3. **Enhanced Image Generation Interface**: A new UI component for the FLUX.1-dev image generation with parameters for prompt, seed, dimensions, guidance scale, and inference steps
+4. **Keyword Trend Analysis Panel**: A dedicated section showing how frequently new content appears for specific keywords
+
+### UI Consistency Requirements
+
+- Maintain existing navigation patterns and sidebar components
+- Use consistent typography as defined in frontend/src/css/typography.css
+- Apply the existing component styles from frontend/src/css/components/

+# Tech-Spec: Browser Integration (Saved Passwords & Text)
+
+**Created:** 2025-12-20
+**Status:** Ready for Development
+
+## Overview
+
+### Problem Statement
+Users experience friction in two main areas:
+1.  **Authentication**: Browser password managers fail to auto-fill or suggest saving credentials because the login and registration forms lack semantic `autocomplete` attributes.
+2.  **Content Creation**: Users often find interesting text while browsing (e.g., on LinkedIn or news sites) but have to manually copy-paste across tabs, which is slow and breaks their workflow.
+
+### Solution
+1.  **Form Optimization**: Enhance `<input>` tags with standard `autocomplete` values to enable native browser credential management.
+2.  **Clipboard Integration**: Add a "Paste from Clipboard" feature in the post editor to simplify text ingestion.
+3.  **Content Bookmarklet**: Provide a "Send to Lin" bookmarklet that allows users to instantly push selected text or the current page title/URL from any website into the Lin post editor.
+
+### Scope (In/Out)
+-   **In**:
+    -   Modifying `Login.jsx` and `Register.jsx` to support auto-fill.
+    -   Implementing Clipboard API support in `Posts.jsx`.
+    -   Adding a new "Tools" page to host instructions and the draggable bookmarklet.
+    -   Handling URL parameters for content pre-filling.
+-   **Out**:
+    -   Native browser extensions (Chrome Web Store, etc.).
+    -   Multi-browser sync of the bookmarklet itself.
+
+## Context for Development
+
+### Codebase Patterns
+-   **Frontend**: React (Vite-based) with Tailwind CSS for styling.
+-   **Routing**: `react-router-dom` v6 for navigation.
+-   **State**: Redux Toolkit used for posts and authentication state.
+-   **API**: Backend communication via `apiClient` (axios).
+
+### Files to Reference
+-   [Login.jsx](file:///c:/Users/othil/Documents/Project/flux%20rss%20ai/Lin/frontend/src/pages/Login.jsx)
+-   [Register.jsx](file:///c:/Users/othil/Documents/Project/flux%20rss%20ai/Lin/frontend/src/pages/Register.jsx)
+-   [Posts.jsx](file:///c:/Users/othil/Documents/Project/flux%20rss%20ai/Lin/frontend/src/pages/Posts.jsx)
+-   [App.jsx](file:///c:/Users/othil/Documents/Project/flux%20rss%20ai/Lin/frontend/src/App.jsx)
+
+### Technical Decisions
+-   **Bookmarklet URL**: The bookmarklet will use `window.location.href` to redirect to `https://[your-lin-url]/posts?text=[content]`.
+-   **Clipboard Permissions**: Will use `navigator.clipboard.readText()`, handling the potential `PermissionDenied` error with a graceful fallback (manual paste instruction).
+
+## Implementation Plan
+
+### Tasks
+
+- [ ] **Task 1: Enhance Auth Forms for Password Managers**
+  - Add `autocomplete="username"` / `autocomplete="current-password"` to `Login.jsx`.
+  - Add `autocomplete="email"` / `autocomplete="new-password"` to `Register.jsx`.
+- [ ] **Task 2: Integrate Clipboard and URL Pre-fill in Posts**
+  - Extract `text` from URL search parameters on component mount.
+  - Add "Paste from Clipboard" button with icon in the `postContent` area.
+  - Implement error handling for clipboard access.
+- [ ] **Task 3: Create Tools/Bookmarklet Page**
+  - Add a New `Tools.jsx` page.
+  - Implement a draggable link with the bookmarklet script.
+  - Update `Sidebar.jsx` and `App.jsx` to include the new Tools route.
+
+### Acceptance Criteria
+
+- [ ] **AC 1**: When visiting the login page, browsers with saved credentials offer to auto-fill.
+- [ ] **AC 2**: After registration or login, the browser asks "Would you like to save this password?".
+- [ ] **AC 3**: Clicking "Paste" in the post editor successfully populates the textarea with the clipboard content (after permission is granted).
+- [ ] **AC 4**: Using the bookmarklet on any webpage redirects the user to Lin with the text field pre-populated.
+
+## Additional Context
+
+### Dependencies
+-   Standard browser Web APIs (Clipboard, URLSearchParams).
+
+### Testing Strategy
+-   **Manual**: Test in Chrome and Firefox for credential handling.
+-   **Manual**: Verify the bookmarklet from a local file or a live site.
+
+### Notes
+-   Ensure the bookmarklet URL is dynamically generated or configurable to match the user's current environment (dev vs prod).

+# Sprint Change Proposal: Keyword Analysis UI Flow and Algorithm Correction
+
+## Analysis Summary
+
+### Original Issue
+The original documentation for keyword analysis did not accurately reflect the required functionality. The issue involved two main aspects:
+1. The algorithm was incorrectly described as simple frequency analysis rather than pattern recognition based on both recency and frequency
+2. The UI flow incorrectly specified dynamic button behavior that changes from "Analyze" to "Add Source" after analysis
+
+### Impact Analysis
+- **Epic Impact**: Epic 1 documentation needed updates to accurately reflect the frequency pattern analysis requirements
+- **Story Impact**: Story 1.2 documentation required comprehensive revision to accurately describe the algorithm and UI flow requirements
+- **Artifact Conflict**: Previous documentation did not align with the actual requirements for pattern recognition and UI workflow
+- **MVP Scope Impact**: The core functionality remains the same, but both the algorithm requirements and UI workflow are more specific and accurate
+
+### Rationale for the Chosen Path Forward
+The changes were necessary because the original story and epic documents described an oversimplified version of keyword analysis that would not meet the actual requirements. The correct implementation must:
+1. Analyze frequency patterns (daily, weekly, monthly, rare) based on both recency and frequency of links from RSS feeds
+2. Maintain a clear UI workflow with separate analysis and add source sections
+3. Keep the "Analyze" button state static without changing to "Add Source" after analysis
+
+## Specific Proposed Edits
+
+### 1. Story 1.2: Keyword Frequency Pattern Analysis Implementation
+**File**: `docs/prd/stories/story-1.2-keyword-trend-analysis-implementation.md`
+
+**Before**:
+- Described simple frequency analysis over time
+- Incorrectly specified dynamic button behavior (Analyze → Add Source)
+- Did not include requirements for pattern recognition considering both recency and frequency
+
+**After**:
+- Accurately describes analysis of frequency patterns (daily, weekly, monthly, rare) considering both recency and frequency
+- Specifies separate UI sections: analysis section appears before add source section
+- Removes dynamic button behavior - button stays as "Analyze" after analysis
+- Added specific algorithm requirements for each pattern type:
+  * Daily: Many links per day consistently with recent activity
+  * Weekly: Links accumulate to about 3-7 per week
+  * Monthly: Less frequent than weekly
+  * Rare: Very scarce with long intervals between them
+- Updated technical implementation guidance to reflect static button behavior
+- Updated acceptance criteria to include UI flow requirements:
+  * Criteria #10: UI has separate sections with analysis before add source
+  * Criteria #11-13: Button behavior remains static after analysis
+- Updated integration verification to check proper section ordering
+- Updated testing guidance to include UI flow between sections
+
+### 2. Epic 1: UI/UX Improvements and Keyword Analysis Enhancement
+**File**: `docs/prd/epic-1-uiux-improvements-and-keyword-analysis-enhancement.md`
+
+**Before**:
+- Story 1.2 section described simple frequency analysis
+- Did not include requirements for pattern recognition and static button behavior
+
+**After**:
+- Updated Story 1.2 section to match the corrected story
+- Accurately describes analysis of frequency patterns considering both recency and frequency
+- Includes new acceptance criteria for UI flow requirements (#10-13)
+- Updates integration verification to include check for analysis section appearing before add source section (IV4)
+
+## Next Steps
+
+The changes have been successfully implemented. The documentation now accurately reflects the requirements for:
+1. Keyword analysis that determines frequency patterns (daily, weekly, monthly, rare) based on both recency and frequency of links from RSS feeds
+2. UI flow with separate analysis and add source sections
+3. Static "Analyze" button behavior that doesn't change after analysis
+
+The development team can now proceed with implementing the feature based on these corrected specifications. The "Correct Course Task" is complete regarding analysis and change proposal. These documents provide the necessary context for implementing the proper keyword frequency pattern analysis algorithm with the correct UI workflow.

+# Story: LinkedIn Scheduling Fix
+
+## Status
+done
+
+## Story
+**As a** user,
+**I want** scheduled LinkedIn posts to actually publish when the scheduled time arrives,
+**so that** my scheduled content is automatically posted to LinkedIn without requiring manual intervention.
+
+## Acceptance Criteria
+1. Scheduled LinkedIn posts execute at the specified time
+2. The scheduled post follows the same workflow as manual "generate then publish"
+3. The system provides clear feedback when scheduling fails
+4. Existing manual publishing functionality continues to work unchanged
+5. Integration with LinkedIn API maintains current behavior
+6. Change is covered by appropriate tests (scheduler execution tests)
+7. Error logging is updated to capture scheduling failures
+8. No regression in existing manual publishing functionality
+
+## Tasks / Subtasks
+- [x] Investigate why scheduled LinkedIn posts are not executing
+  - [x] Examine scheduler job execution path
+  - [x] Compare with manual publish execution path
+  - [x] Check authentication token handling for scheduled jobs
+- [x] Fix scheduler execution to match manual publish flow (AC: #1, #2)
+  - [x] Update scheduler to use same posting workflow as manual publish
+  - [x] Ensure proper authentication context for scheduled jobs
+- [x] Update error logging to capture scheduling failures (AC: #3, #7)
+  - [x] Add specific logging for LinkedIn scheduler jobs
+  - [x] Ensure errors are visible in logs
+- [x] Verify manual publishing continues to work (AC: #4, #8)
+  - [x] Test manual publish functionality after changes
+  - [x] Ensure no regression in existing functionality
+- [x] Add/update tests for scheduler functionality (AC: #6)
+  - [x] Create tests for LinkedIn scheduler execution
+  - [x] Verify existing manual publish tests still pass
+
+## Dev Notes
+This story addresses an issue where scheduled LinkedIn posts are not being published, while manual "generate then publish" functionality works correctly. The scheduler likely creates a job that doesn't properly execute the same posting workflow as the manual function.
+
+The fix should ensure that the scheduler uses the same execution pathway as the manual publish flow, paying special attention to authentication token handling which may differ between immediate execution (manual) and delayed execution (scheduled).
+
+### Testing
+List Relevant Testing Standards from Architecture the Developer needs to conform to:
+- Test file location: tests/scheduler_tests.py
+- Test standards: Follow existing pytest patterns in the codebase
+- Testing frameworks and patterns to use: pytest with proper mocking for LinkedIn API calls
+- Any specific testing requirements for this story: Need to test both successful scheduling and error handling scenarios

+- **Generated:** 2025-11-22
+- **Version:** 1.0
+
+## Context Summary
+
+### Documents Available:
+- PRD (Product Requirements Document) for LinkedIn community manager enhancements
+- Architecture document detailing the system structure
+- Keyword frequency analysis implementation documentation
+- Existing user authentication and registration flow
+- Database schema with profiles table for user metadata
+
+### Project Type:
+Brownfield project - LinkedIn community management tool with React frontend and Flask backend
+
+### Existing Stack:
+- Frontend: React 18.2.0, Vite, Redux Toolkit, Tailwind CSS
+- Backend: Flask 3.1.1, Python 3.8+
+- Database: Supabase (PostgreSQL)
+- External APIs: LinkedIn API, Google News RSS, Gradio client for AI interactions
+- Task Queue: Celery + Redis
+- Infrastructure: Docker with docker-compose, Nginx reverse proxy
+
+### Code Structure:
+- Well-structured with clear separation between frontend and backend
+- Established API patterns and Redux state management
+- Existing features include RSS source management, AI content generation, and post scheduling
+- User profiles stored in Supabase with JSONB metadata field for additional user information
+
+## Problem Statement
+
+The current LinkedIn post generation system only supports US and English parameters when generating RSS feeds from keywords. This limits the global reach of the application by not considering the user's country and language preferences during content generation. The system needs to be enhanced to:
+
+1. Collect user's country and language preferences during registration
+2. Generate RSS feeds based on the user's country (not just US)
+3. Support both English and French languages for the same country
+4. Merge dataframes from both languages into one for processing
+5. Implement the merging logic in the backend keyword analysis function
+
+## Solution Overview
+
+The solution involves implementing user preferences for country and language that will be used in RSS generation. This includes:
+1. Modifying user registration to collect country and language preferences
+2. Updating the RSS generation function to use user-specific parameters
+3. Creating logic to generate both English and French RSS feeds for the same country
+4. Merging the resulting dataframes from both languages
+5. Updating the keyword analysis function to handle merged dataframes
+
+## Scope
+
+### In Scope:
+- Modifying user registration flow to collect country and language preferences
+- Updating the `generate_google_news_rss_from_string` function to accept country/language parameters
+- Modifying the RSS generation logic in `ai_agent.py` to generate feeds for both languages
+- Implementing dataframe merging logic in the content service for keyword analysis
+- Updating user profile management to store country and language preferences
+- Modifying the frontend to collect country and language during registration
+
+### Out of Scope:
+- Changing the Supabase database schema (using existing JSONB field)
+- Modifying the LinkedIn posting functionality itself
+- Adding language translation for the UI
+- Adding additional languages beyond English and French
+
+## Source Tree Changes
+
+### Backend Changes:
+- `backend/api/auth.py` - MODIFY - Add country and language to registration endpoint
+- `backend/services/auth_service.py` - MODIFY - Update register_user function to store preferences
+- `backend/models/user.py` - MODIFY - Add methods to update user preferences
+- `Linkedin_poster_dev/ai_agent.py` - MODIFY - Update `generate_google_news_rss_from_string` function and article_reader function
+- `backend/services/content_service.py` - MODIFY - Update `_generate_google_news_rss_from_string` method and implement dataframe merging in keyword analysis
+- `backend/api/sources.py` - MODIFY - Add endpoint to update user preferences if needed
+
+### Frontend Changes:
+- `frontend/src/pages/Register.jsx` - MODIFY - Add country and language selection during registration
+- `frontend/src/pages/Settings.jsx` - CREATE/MODIFY - Add ability to update country/language preferences
+- `frontend/src/services/authService.js` - MODIFY - Update registration payload
+- `frontend/src/components/CountryLanguageSelector.jsx` - CREATE - New component for country/language selection
+
+## Technical Approach
+
+### Backend Implementation:
+Use existing Supabase `profiles` table with `raw_user_meta` JSONB field to store user preferences. The `raw_user_meta` field will contain:
+```json
+{
+  "country": "FR",
+  "language": "fr",
+  "preferred_languages": ["en", "fr"]
+}
+```
+
+Follow the existing patterns for user profile updates using the Supabase client. The `generate_google_news_rss_from_string` function will be updated to accept country and language parameters instead of hardcoded "US" and "en".
+
+### Frontend Implementation:
+Use React with existing Redux Toolkit state management. Create a reusable component for country and language selection that follows the existing Tailwind CSS design system with colors: primary: #910029, secondary: #39404B, accent: #ECF4F7.
+
+### Dataframe Merging:
+Implement pandas-based dataframe concatenation in the content service to merge articles from both English and French RSS feeds for the same country. Remove duplicates based on article link to avoid duplication.
+
+## Existing Patterns to Follow
+
+Follow the service pattern established in existing services:
+
+- Use class-based services with constructor dependency injection
+- Use async/await for all asynchronous operations
+- Throw custom error classes with error codes
+- Include JSDoc-style Python docstrings for all public methods
+- Follow existing error handling patterns in the application
+- Use the existing authentication middleware for all new endpoints
+- Follow the existing Redux store patterns in frontend
+
+## Integration Points
+
+### Internal Modules:

+- `@/services/ContentService` - Content processing and analysis
+- `@/components/Header` and `@/components/Sidebar` - Existing UI components
+
+### Configuration Changes:
+- Update README.md to document new user preference functionality
+- Add country/language options to frontend form validation
+
+## Existing Conventions
+
+Brownfield project with established conventions:
+- JavaScript/TypeScript: camelCase naming, ESLint with React plugin linting
+- Python: snake_case naming, PEP 8 compliant
+- File organization: Group by feature in frontend, by type in backend
+- API endpoints: RESTful patterns with JWT authentication
+- Testing: pytest for backend, Jest/React Testing Library for frontend
+- Import style: Grouped by external libraries, internal modules, relative imports
+- Error handling: Consistent response format with success/error flags
+
+## Implementation Stack
+
+- Runtime: Node.js 20.x (frontend), Python 3.8+ (backend)
+- Framework: Flask 3.1.1 (backend), React 18.2.0 (frontend)
+- Language: JavaScript/TypeScript, Python
+- Testing: pytest 8.4.1 (backend), Jest (frontend)
+- Linting: ESLint 8.57.0 (frontend), flake8 (backend)
+- Styling: Tailwind CSS with custom configuration
+- Database: Supabase (PostgreSQL)
+- State Management: Redux Toolkit
+
+## Technical Details
+
+### User Preference Storage:
+Use the existing `profiles` table's `raw_user_meta` JSONB field to store user preferences:
+- Store country as ISO 3166-1 alpha-2 code (e.g., "US", "FR", "DE")
+- Store language as ISO 639-1 code (e.g., "en", "fr")
+- Store additional languages in an array for multi-language support
+
+### RSS Generation Logic:
+- Modify the `generate_google_news_rss_from_string` function to accept user-specific country and language parameters
+- For each keyword, generate RSS feeds for both English and French if both are preferred
+- When processing RSS feeds in `article_reader`, generate both language feeds for the user's country
+- Merge the resulting dataframes, removing duplicates based on article URL
+
+### Dataframe Merging Algorithm:
+```python
+def merge_language_dataframes(df_english, df_french):
+    # Combine both dataframes
+    df_combined = pd.concat([df_english, df_french], ignore_index=True)
+    
+    # Remove duplicates based on the 'link' column
+    df_deduplicated = df_combined.drop_duplicates(subset=['link'], keep='first')
+    
+    # Sort by date in descending order (most recent first)
+    df_deduplicated = df_deduplicated.sort_values(by='date', ascending=False)
+    
+    return df_deduplicated
+```
+
+### RSS URL Generation:
+- Generate URLs with format: `https://news.google.com/rss/search?q={query}&hl={language}&gl={country}&ceid={country}:{language}`
+- For the current user, generate both English and French feeds for their country
+- Example: if user is from France, generate feeds for `hl=fr&gl=FR&ceid=FR:fr` and `hl=en&gl=FR&ceid=FR:en`
+
+### Performance Considerations:
+- Cache RSS feeds to prevent excessive API calls
+- Implement rate limiting for RSS feed requests
+- Use efficient pandas operations for dataframe merging
+- Optimize database queries to retrieve user preferences efficiently
+
+### Security Considerations:
+- Validate country and language codes against known standards
+- Sanitize user inputs for country and language selection
+- Maintain existing JWT authentication for all new endpoints
+- Ensure ISO code validation to prevent injection attacks
+
+### Error Handling:
+- Provide default country/language if user preferences are not set
+- Handle RSS feed generation failures gracefully
+- Log errors appropriately for debugging
+- Display user-friendly error messages
+
+## Development Setup
+
+1. Navigate to project root directory
+2. Install backend dependencies: `cd backend && pip install -r requirements.txt`
+3. Install frontend dependencies: `cd frontend && npm install`
+4. Set up environment variables from .env.example
+5. Run the development servers: `npm run dev` (runs both frontend and backend)
+6. Run tests: `npm run test` for frontend, `npm run test:backend` for backend
+
+## Implementation Guide
+
+### Setup Steps:
+1. Create feature branch from main
+2. Verify dev environment is running correctly
+3. Review existing user profile management patterns
+4. Set up test data for country/language preferences
+
+### Implementation Steps:
+
+#### Story 1: User Preference Collection
+1. Update user registration form in `frontend/src/pages/Register.jsx` to include country and language selection
+2. Add country/language validation and selection component in `frontend/src/components/CountryLanguageSelector.jsx`
+3. Update `authService.js` to include preferences in registration payload
+4. Modify `backend/api/auth.py` registration endpoint to accept preferences
+5. Update `backend/services/auth_service.py` to store preferences in user profile
+6. Update `backend/models/user.py` with methods to manage preferences
+
+#### Story 2: RSS Generation with User Preferences
+1. Modify `generate_google_news_rss_from_string` function in `Linkedin_poster_dev/ai_agent.py` to accept country and language parameters
+2. Update `article_reader` function to generate feeds for both English and French for user's country
+3. Implement dataframe merging logic in `article_reader` to combine results from both languages
+4. Update `content_service.py` with similar logic for keyword analysis
+5. Test RSS feed generation with various country/language combinations
+
+### Testing Strategy:
+- Unit tests for user preference storage and retrieval
+- Integration tests for modified RSS generation functions
+- Frontend component tests for country/language selection
+- End-to-end tests for the registration flow with preferences
+- Test RSS feed generation with different country/language combinations
+
+### Acceptance Criteria:
+1. Given a new user registers, when they specify country and language preferences, then system stores these preferences in the user profile
+2. Given user has specified preferences, when the system generates RSS feeds, then feeds are generated using the user's country and both English and French languages
+3. Given RSS feeds from both languages are generated, when system processes articles, then dataframes are properly merged without duplicates
+4. Given keyword analysis is performed, when user preferences exist, then system analyzes content from both language feeds for the user's country
