Resolve a 13F FILER name to its CIK -- the front door to get_13f_holdings and ol_13f_filer_analytics when you know the manager ('Berkshire Hathaway', 'Baupost') and not its CIK (search_company resolves ISSUERS). Returns {summary, query, filers: [{cik, name, last_filing, page_url}], count}; name-PREFIX matches rank first. THE UNIVERSE IS CURATED -- the filers Oxford Ledge ingests plus featured filers, never a live EDGAR full-text search. filers=[] means the store answered and nothing matched; an unreachable store is REFUSED (DATA_UNAVAILABLE). `query` 3-80 characters; `limit` default 5, hard cap 10. Source: SEC EDGAR 13F-HR (public domain; Oxford Ledge derived); FREE. Caveats ride the response's tool_notes.
