HCD.6:4.7 - Recognition and Assurance

Recognition. Use HCD.6 when practice feels busy or realistic but the practitioner cannot say which human action the task elicits, which condition changes the correct move, or what the learner must do without an answer-bearing cue.

Assurance. Stronger reliance needs a qualified target-domain oracle, safe and accessible conditions, explicit support allocation, criteria that discriminate warranted action from critical error, and a task relation suitable for the intended evidence claim. Domain experts retain correctness and hazard decisions; performed-attempt and capability claims require their own evidence.
