# HKIA Content Aggregation System
## Project Overview
-Complete content aggregation system that scrapes 5 sources (WordPress, MailChimp RSS, Podcast RSS, YouTube, Instagram), converts to markdown, and runs twice daily with incremental updates. TikTok scraper disabled due to technical issues.
+Complete content aggregation system that scrapes 6 sources (WordPress, MailChimp RSS, Podcast RSS, YouTube, Instagram, HVACRSchool), converts to markdown, and runs twice daily with incremental updates. TikTok scraper disabled due to technical issues.
## Architecture
-- **Base Pattern**: Abstract scraper class with common interface
-- **State Management**: JSON-based incremental update tracking
-- **Parallel Processing**: All 5 active sources run in parallel
+- **Base Pattern**: Abstract scraper class (`BaseScraper`) with common interface
+- **State Management**: JSON-based incremental update tracking in `data/.state/`

-- **Archive System**: Previous files archived to timestamped directories
+- **Archive System**: Previous files archived to timestamped directories in `data/markdown_archives/`

## Critical Notes
1. **✅ TikTok Scraper**: DISABLED - No longer blocks deployment or requires GUI access
2. **Instagram Rate Limiting**: 100 requests/hour with exponential backoff
-3. **YouTube Transcript Limitations**: As of August 2025, YouTube blocks transcript extraction
- - PO token requirements prevent `yt-dlp` access to subtitle/caption data
+3. **YouTube Transcript Status**: DISABLED in production due to platform restrictions (Aug 2025)
+ - Complete PO token implementation but blocked by YouTube platform changes
- 179 videos identified with captions but currently inaccessible
- - Authentication system works but content restricted at platform level
-4. **State Files**: Located in `data/markdown_current/.state/` directory for incremental updates
-5. **Archive Management**: Previous files automatically moved to timestamped archives
-6. **Error Recovery**: All scrapers handle rate limits and network failures gracefully
-7. **✅ Production Services**: Fully automated with systemd timers running twice daily

-## YouTube Transcript Investigation (August 2025)
+## YouTube Transcript Status (August 2025)
-**Objective**: Extract transcripts for 179 YouTube videos identified as having captions available.
+**Current Status**: ❌ **DISABLED** - Transcripts extraction disabled in production
-**Investigation Findings**:
-- ✅ **179 videos identified** with captions from existing YouTube data
-- ✅ **Existing authentication system** (`YouTubeAuthHandler` + Firefox cookies) working
-- ✅ **Transcript extraction code** properly implemented in `YouTubeScraper`
-- ❌ **Platform restrictions** blocking all video access as of August 2025
+**Implementation Status**:
+- ✅ **Hybrid Scraper**: Complete (`src/youtube_hybrid_scraper.py`)
+- ✅ **PO Token Handler**: Full implementation with environment variable support
+- ✅ **Firefox Integration**: Cookie extraction and profile detection working
+- ✅ **API Integration**: YouTube Data API v3 for efficient metadata extraction
+- ❌ **Transcript Extraction**: Disabled due to YouTube platform restrictions
-**Technical Attempts**:
-1. **YouTube Data API v3**: Requires OAuth2 for `captions.download` (not just API keys)
-2. **youtube-transcript-api**: IP blocking after minimal requests
-3. **yt-dlp with authentication**: All videos blocked with "not available on this app"
+**Technical Details**:
+- **179 videos identified** with captions available but currently inaccessible
+- **PO Token**: Extracted and configured (`YOUTUBE_PO_TOKEN_MWEB_GVS` in .env)
+- **Authentication**: Firefox cookies (147 extracted) + PO token support
+- **Platform Error**: "The following content is not available on this app"
-**Current Blocker**:
-YouTube's new PO token requirements prevent access to video content and transcripts, even with valid authentication. Error: "The following content is not available on this app.. Watch on the latest version of YouTube."
+**Architecture**: True hybrid approach maintains efficiency:
+- **Metadata**: YouTube Data API v3 (cheap, reliable, rich data)
+- **Transcripts**: yt-dlp with authentication (currently blocked)
+- **Fallback**: Gracefully continues without transcripts
-**Resolution**: Requires upstream `yt-dlp` updates to handle new YouTube platform restrictions.
+**Future**: Will automatically resume transcript extraction when platform restrictions are resolved.
## Project Status: ✅ COMPLETE & DEPLOYED
-- **5 active sources** working and tested (TikTok disabled)
+- **6 active sources** working and tested (TikTok disabled)
- **✅ Production deployment**: systemd services installed and running
- **✅ Automated scheduling**: 8 AM & 12 PM ADT with NAS sync
- **✅ Comprehensive testing**: 68+ tests passing
-- **✅ Real-world data validation**: All sources producing content
-- **✅ Full backlog processing**: Verified for all active sources
+- **✅ Real-world data validation**: All 6 sources producing content (Aug 27, 2025)
+- **✅ Full backlog processing**: Verified for all active sources including HVACRSchool
+- **✅ System reliability**: WordPress/MailChimp issues resolved, all sources updating
- **✅ Cumulative markdown system**: Operational
- **✅ Image downloading system**: 686 images synced daily
- **✅ NAS synchronization**: Automated twice-daily sync
