A CIK is the SEC’s numeric identifier for a filer. Tickers can change; CIKs are the join key for submissions and XBRL companyfacts.
Without a CIK, the desk cannot honestly list filings or pull tagged financials. Showing a blank OWN/FIL panel is better than guessing.
Fundamentals sync and the filings helper resolve ticker → CIK via SEC company_tickers, then fetch submissions JSON.
