Insider Buying Scanner
Current Understanding
Scrapes SEC Form 4 filings. CEO/CFO purchases >$100K are the most reliable signal. Cluster detection (2+ insiders buying within 14 days) historically a high-conviction setup. Transaction details (name, title, value) must be preserved from scraper output and included in candidate context — dropping them loses signal clarity.

Pending Hypotheses
- Does cluster detection (2+ insiders in 14 days) outperform single-insider signals?
- Is there a minimum transaction size below which signal quality degrades sharply?
