Ben Reed 05218a873b Fix critical production issues and improve spec compliance 
Production Readiness Improvements:
- Fixed scheduling to match spec (8 AM & 12 PM ADT instead of 6 AM/6 PM)
- Enabled NAS synchronization in production runner with error handling
- Fixed file naming convention to spec format (hvacknowitall_combined_YYYY-MM-DD-THHMMSS.md)
- Made systemd services portable (removed hardcoded user/paths)
- Added environment variable validation on startup
- Moved DISPLAY/XAUTHORITY to .env configuration

Systemd Improvements:
- Created template service file (@.service) for any user
- Changed all paths to /opt/hvac-kia-content
- Updated installation script for portable deployment
- Fixed service dependencies and resource limits

Documentation:
- Created comprehensive PRODUCTION_TODO.md with 25 tasks
- Added PRODUCTION_GUIDE.md with deployment instructions
- Documented spec compliance gaps (65% complete)

Remaining work includes retry logic, connection pooling, media downloads,
and pytest test suite as documented in PRODUCTION_TODO.md

HVAC Know It All Content Aggregation System

Project Overview

Complete content aggregation system that scrapes 6 sources (WordPress, MailChimp RSS, Podcast RSS, YouTube, Instagram, TikTok), converts to markdown, and runs twice daily with incremental updates.

Architecture

  • Base Pattern: Abstract scraper class with common interface
  • State Management: JSON-based incremental update tracking
  • Parallel Processing: 5 sources run in parallel, TikTok separate (GUI requirement)
  • Output Format: hvacknowitall_[source]_[timestamp].md
  • Archive System: Previous files archived to timestamped directories
  • NAS Sync: Automated rsync to /mnt/nas/hvacknowitall/

Key Implementation Details

Instagram Scraper (src/instagram_scraper.py)

  • Uses instaloader with session persistence
  • Aggressive rate limiting: 15-30 second delays, extended breaks every 5 requests
  • Session file: instagram_session_hvacknowitall1.session
  • Authentication: Username hvacknowitall1, password I22W5YlbRl7x

TikTok Scraper (src/tiktok_scraper_advanced.py)

  • Advanced anti-bot detection using Scrapling + Camofaux
  • Requires headed browser with DISPLAY=:0
  • Stealth features: geolocation spoofing, OS randomization, WebGL support
  • Cannot be containerized due to GUI requirements

YouTube Scraper (src/youtube_scraper.py)

  • Uses yt-dlp for metadata extraction
  • Channel: @HVACKnowItAll
  • Fetches video metadata without downloading videos

RSS Scrapers

  • MailChimp: https://us10.campaign-archive.com/feed?u=d1a98c3e62003104038942e21&id=2205dbf985
  • Podcast: https://feeds.libsyn.com/568690/spotify

WordPress Scraper (src/wordpress_scraper.py)

  • Direct API access to hvacknowitall.com
  • Fetches blog posts with full content

Technical Stack

  • Python: 3.11+ with UV package manager
  • Key Dependencies:
    • instaloader (Instagram)
    • scrapling[all] (TikTok anti-bot)
    • yt-dlp (YouTube)
    • feedparser (RSS)
    • markdownify (HTML conversion)
  • Testing: pytest with comprehensive mocking

Deployment Strategy

⚠️ IMPORTANT: systemd Services (Not Kubernetes)

Originally planned for Kubernetes deployment but TikTok requires headed browser with DISPLAY=:0, making containerization impossible.

Production Setup

# Service files location
/etc/systemd/system/hvac-scraper.service
/etc/systemd/system/hvac-scraper.timer
/etc/systemd/system/hvac-scraper-nas.service  
/etc/systemd/system/hvac-scraper-nas.timer

# Installation directory
/opt/hvac-kia-content/

# Environment setup
export DISPLAY=:0
export XAUTHORITY="/run/user/1000/.mutter-Xwaylandauth.90WDB3"

Schedule

  • Main Scraping: 8AM and 12PM Atlantic Daylight Time
  • NAS Sync: 30 minutes after each scraping run
  • User: ben (requires GUI access for TikTok)

Environment Variables

# Required in /opt/hvac-kia-content/.env
INSTAGRAM_USERNAME=hvacknowitall1
INSTAGRAM_PASSWORD=I22W5YlbRl7x
YOUTUBE_CHANNEL=@HVACKnowItAll
TIKTOK_USERNAME=hvacknowitall
NAS_PATH=/mnt/nas/hvacknowitall
TIMEZONE=America/Halifax
DISPLAY=:0
XAUTHORITY="/run/user/1000/.mutter-Xwaylandauth.90WDB3"

Commands

Testing

# Test individual sources
uv run python test_real_data.py --source [youtube|instagram|tiktok|wordpress|mailchimp|podcast]

# Test backlog processing  
uv run python test_real_data.py --type backlog --items 50

# Full test suite
uv run pytest tests/ -v

Production Operations

# Run orchestrator manually
uv run python -m src.orchestrator

# Run specific sources
uv run python -m src.orchestrator --sources youtube instagram

# NAS sync only
uv run python -m src.orchestrator --nas-only

# Check service status
sudo systemctl status hvac-scraper.service
sudo journalctl -f -u hvac-scraper.service

Critical Notes

  1. TikTok GUI Requirement: Must run on desktop environment with DISPLAY=:0
  2. Instagram Rate Limiting: 100 requests/hour with exponential backoff
  3. State Files: Located in state/ directory for incremental updates
  4. Archive Management: Previous files automatically moved to timestamped archives
  5. Error Recovery: All scrapers handle rate limits and network failures gracefully

Project Status: ✅ COMPLETE

  • All 6 sources working and tested
  • Production deployment ready via systemd
  • Comprehensive testing completed (68+ tests passing)
  • Real-world data validation completed
  • Full backlog processing capability verified
