HCD.7 and HCD.8: supply feasible providers, sources, tools, AI, environments, capacity, human checking, and any built contribution for the selected episodes.
HCD.9: supplies attempt, actual-help, feedback, correction, retry, and next-focus evidence; HCD.10 selects what changes across later episodes.
E.23.CAE: can differentiate applicability, access, expression, adaptation, enactment, support, and capability-change explanations when they would alter the next practice decision; it does not select HCD.10’s practice change.
HCD.11: may use a compatible condition-sensitive attempt for a bounded performance inference without treating schedule form as evidence.
HCD.12: governs unfamiliar-transfer interpretation; variation or interleaving alone establishes no transfer.
HCD.13: governs delay, intervening-practice, source, and support interpretations; a scheduled later episode establishes no retention by form.
HCD.14: may revise only the affected Method, task, schedule, support, or evidence assumption from compatible results.
Learning-product practices: may implement the concrete calendar, task sequence, prompts, resources, and interfaces; HCD.10 owns the person- and target-relative progression rationale and evidence boundary.
Target-domain, safety, privacy, legal, employment, provider, platform, assessment, and authority practices: retain correctness, access, risk, capacity, and consequential decisions.
