Client.SendMessage(title, raw, targets) creates a private-message topic by posting to /posts.json with target_usernames / target_group_names / target_emails (comma-joined on the wire, as Discourse expects, never JSON arrays) instead of a category. The result reuses the topic ids type, so URL() renders the PM link. Local validation requires title, body and at least one target; undeliverable recipients surface as the typed ErrForbidden class. Fake-server tests assert the wire shape and the recorded recipients. Part of Redmine 507 (Discourse Go client): PM delivery is how the 495 pipeline pings humans that a briefing has landed.
