A discrete instance in which a user identifies a previously unknown capability of an AI system through exploration or experimentation. It marks an observable moment of first encountering a new affordance.
EVENT. Counted once per session in which a user first elicits and recognises a system capability they had not previously used, evidenced by exploratory prompting followed by a recognition marker ('oh, it can also...'). Re-use of known capabilities is excluded.
Proposed measurement protocol (not yet empirically validated): Rater-coded count of first-encounter capability events per user over a usage period, cross-referenced against the user's prior capability set; could be reported as discoveries per session. Coder agreement on novelty judgement via Cohen's kappa.
