HCD.8: receives an exact unavailable provider, environment, assessment, or support contribution for obtain-or-build comparison and the preparation or operating test actually needed. Already established usable contributions can be arranged directly through HCD.7.
HCD.9: uses the enabled arrangement and records help actually received, feedback delivered, corrections, and provider failures during practice.
HCD.10: may change support across practice episodes for a stated development or evidence purpose; the revised arrangement must remain feasible.
HCD.11–HCD.13: interpret supported, independent, transferred, delayed, and changed-support performance; availability alone establishes none of them.
HCD.14: may revise only the affected support assumption or programme component from compatible evidence.
Learning-product practices: can specify concrete materials, interactions, and schedules; publication or access does not establish provider competence or service operation.
Organization, operations, platform, privacy, safety, legal, clinical, employment, accessibility, provider, and target-domain practices: retain their own capacity, authority, competence, data, risk, and correctness decisions.
