HCD.9:9 - Consequences
The learner receives feedback that can change a specific next action, and the practitioner receives a replayable account of what the person did before and after help. Successful requirements can be preserved, critical errors remain visible, and the next episode follows evidence rather than generic repetition.
The cost is detailed episode evidence and provider time. Tasks need observable criteria and a valid retry; feedback must arrive while it can still be used; and attribution may reveal that an apparently improved product says little about the learner. Not every difficulty fits the planned slot.
