Returns SC 13D / SC 13G blockholder disclosures (5%+ stakes) for a US public company. Each row carries percent_owned, sole/shared voting + dispositive split, schedule_type, and the first-class ``going_active`` flag — TRUE when the same filer flipped 13G → 13D within the lookback window (the single most actionable activist signal in this dataset). Use latest_only=true (default) to dedupe to the most recent filing per filer. Use collapse_groups=true to fold multi-person filings into one row. Institutional tier only.
