## Anti-JS-Rendered Sources

Some major Chinese tech sites (机器之心, 部分36kr pages) are JS-rendered and cannot be fetched with simple HTTP requests. For these:

1. Try RSS feed if available
2. Use Tavily API which handles JS rendering
3. Skip if both fail — don't waste time

## Source Health Check

Periodically verify sources are still active:
- Check last post date (flag if >30 days old)
- Verify URL still resolves
- Check for domain changes or redirects
