Which funds hold a company or bond you name (or its CUSIP or ISIN), from the latest quarterly reports

Which closed-end funds hold a security: [{security, cusip, isin, funds: [{ticker, name, pct_val, pct_of_holdings, as_of, source_url}]}] from every fund's latest N-PORT (grouped by security, exact name first; at most 50 funds per security and 200 fund rows in all). pct_val is the security's share of the fund's NET assets as filed (0-100); pct_of_holdings its share of the fund's long book (what the site prints), which is smaller on funds that borrow.
