Task 18

Enter a ticker. From SEC filings we flag Schedule 13D activist stakes (a positive drift signal) and red flags — dilution (424B5/S-3), late filings (NT 10-K/Q), auditor changes, delisting notices, and adverse executive departures (8-K 5.02, where the LLM reads the text to tell a forced exit from a planned retirement). Keyed off the filing date; long-only — ride activist drift, stand aside on red flags.
