Attributions come from the filings themselves (cover-page XBRL auditor tag, the audit report signature, the former auditor's EX-16 letter or the Item 4.01 text) and are shown only when we are confident; coverage is partial. A going-concern paragraph means the auditor flagged the client's financial position; it is not a criticism of the audit firm. Not investment advice.
