Goal-Match Acknowledgment
A point in an exchange at which the user registers shared satisfaction because the delivered output, the original intention, and the result align. It denotes a user-marked success acknowledgment within the dialogue.
Operational Definition
One occurrence would be coded when a user turn explicitly acknowledges that the output matched the intended goal (an alignment or approval statement immediately following a delivered result). The acknowledging turn is the unit.
Measurement Schema
Proposed measurement protocol (not yet empirically validated): Rater coding of explicit success-acknowledgment turns following deliverables, by two coders, with Cohen's kappa; could be reported as a count per session, optionally with a convergent single-item satisfaction rating (1-7) at the acknowledgment point.
