Bind a visitor to a person of the team by hand ("the visitor from Acme's network yesterday is John"): person_sid, a live playtables person (cr_pp_), else 422 relation_not_found. It overrides any automatic bind; the visitor's open session and its sessions of the last 30 days nobody owned go to the person, their facts written by a queued job. On a site set to companies it is 409 invalid_transition (companies_level). The same person again changes nothing. Undo with unlink_website_visitor.
