🎯 AudioNews.uk v2.3.0 - AI Deduplication & Story Quality Enhancement

🔧 Major AI Analysis Improvement

This release addresses the duplicate story issue reported by Molloy, where multiple instances of the same news topic (e.g., China-related stories) were appearing in the daily digest. The AI analysis system has been comprehensively enhanced with intelligent deduplication.

🎯 Issue Reported by Molloy

• Multiple duplicate stories about the same events (China economy, China trade, China GDP)
• Redundant content reducing digest quality
• Need for intelligent story consolidation

✅ Deduplication Solution Implemented

🤖 Enhanced AI Analysis

• Explicit deduplication instructions: AI now told to select only the BEST/MOST COMPREHENSIVE version of each story
• Clear examples in prompts: 'If you see China economy and China trade and China GDP - pick the best one'
• Strict uniqueness rules: 'Each theme should have UNIQUE, DISTINCT stories - no duplicates allowed'

🔍 Programmatic Safety Net

• Keyword overlap detection: 40% similarity threshold for identifying duplicate stories
• Automatic filtering: Stories with significant keyword overlap are automatically skipped
• Debug logging: Shows when duplicates are detected and removed for transparency

📝 Improved Content Synthesis

• Anti-repetition prompts: 'AVOID repetitive content - synthesize into ONE coherent narrative'
• Story combination: 'If multiple stories are about the same event, combine them into one summary'
• Enhanced system messages: Both OpenAI and Anthropic prompts updated for consistency

🛡️ Fallback Protection

• Enhanced fallback mode: Even if AI fails, keyword-based categorization includes deduplication
• Stricter thresholds: 50% overlap threshold for fallback mode ensures quality

📊 Before vs After Example

Before (Reported Issue):

• 'China's economy shows growth'
• 'China trade figures released'
• 'China GDP data published'

After (Fixed):

• 'China's economy shows growth' (most comprehensive version selected)

🔧 Technical Implementation

• Two-layer deduplication: AI-level + programmatic validation
• Keyword extraction: Smart filtering based on significant terms (>3 characters)
• Overlap calculation: Jaccard similarity for accurate duplicate detection
• Significance scoring: Stories ranked by comprehensiveness and detail

🎧 User Impact

• ✅ No more duplicate stories in daily digests
• ✅ Higher quality content with unique, distinct news items
• ✅ More concise digests without redundant information
• ✅ Better synthesis combining related events into coherent narratives
• ✅ Professional news service matching broadcast standards

🚀 Deployment

• ✅ CI/CD pipeline tested and validated
• ✅ Both AI providers (OpenAI GPT-4, Anthropic Claude 4.5) updated
• ✅ Fallback mode enhanced for reliability
• ✅ Next digest (6 AM UK time) will use improved deduplication

🎧 AudioNews.uk v2.2.0 - Audio Playback Fix & LFS Integration

🎉 Major Audio Playback Fix

This release resolves the critical audio playback issue where the play button was greyed out on the live website. The root cause was that GitHub Pages was serving Git LFS pointer files (131 bytes) instead of the actual audio content (892KB).

• Explicit LFS Pull: Added dedicated git lfs pull step during deployment
• Proper File Deployment: Ensured actual audio files are deployed, not LFS pointers
• CDN Cache Handling: Implemented cache-busting for proper content delivery

✅ What's Fixed

• 🎵 Audio playback button now works - no longer greyed out
• 📁 Correct file sizes: 892KB audio files instead of 131-byte pointers
• 🔄 Reliable deployment: LFS files properly resolved during CI/CD
• 🌐 CDN compatibility: Audio files correctly served through Cloudflare

📊 Before vs After

• Before: Content-Length: 131 (LFS pointer)
• After: Content-Length: 892800 (actual audio file)
• Result: Fully functional audio playback on https://audionews.uk

🧹 Maintenance

• Removed temporary debug files (audio-debug.html, autoplay-test.html)
• Cleaned up repository structure
• Updated deployment workflow for reliability

🎯 User Impact

• ✅ Audio controls are now fully functional
• ✅ Play button works immediately on page load
• ✅ High-quality Irish neural voice audio (Emily Neural)
