## Preferred workflow
Use get_ownership_activity for a company ownership brief. Treat Form 13F results as
quarter-end position changes, not trades. Treat only Form 4 code P as a purchase and S
as a sale. Preserve release IDs, coverage, caveats, claims, and exact SEC filing links.

Authentication uses a scoped pilot credential. Never place credentials in URLs.
