HCD.6:10 - Rationale

A practice task is representative relative to the target contribution and intended evidence claim. It preserves the relations needed for that contribution and use, not every detail of the workplace. This permits bounded safe practice while protecting domain truth.

Supported acquisition and correction can use the same task; a changed-condition attempt answers a different question when recognition or adaptation is required. Separating those uses keeps the learning contribution of help visible while preserving the limits of the resulting evidence. Designing both refusal and continuation cases prevents a safety-oriented boundary from becoming inert caution. The resulting work products give HCD.9 a focused practice object and HCD.11 an interpretable attempt without making their later conclusions in advance.
