Filings the company made itself, as EDGAR lists them; the documents stay on EDGAR. An 8-K is a current report, its item codes read from the filing metadata and coloured by materiality: high bankruptcy, delisting, restatement, change of control · material earnings, M&A, leadership · routine exhibits, Reg FD, votes. Insider trades (Form 4) are on Insiders; 13D/13G and 13F holders on Ownership.
