active flag is derived at READ TIME per the as_of parameter (default = to_date): for each (beneficial_owner_cik, issuer_cik) pair, the LATEST filing with filed_at <= as_of is marked active=True; earlier filings in the same chain are active=False. Supports historical 'who held >X% as of YYYY' queries without blob rewrites.
