The deliberate shaping of an AI system's expressed persona via instructions to fit specific tasks or contexts. It denotes an observable user act of configuring system style, not a trait of the system itself.
EVENT. Counted once per session in which a user issues explicit persona-shaping instructions (role, tone, or character directives intended to set the system's expressed style). Ordinary task instructions without a persona directive are excluded.
Proposed measurement protocol (not yet empirically validated): Rater-coded count of persona-directive turns per session; could be reported as rate per session and share of sessions containing at least one directive. Coder reliability on the persona-vs-task-instruction distinction via Cohen's kappa.
