Investigation-only deliverable. Recommends hybrid design: keep direct AskUserQuestion calls in CC, add PAI-level ENUMERATE→OFFER trigger gate for ALGORITHM + OPEN_CHOICES output field for NATIVE, subagent-bubble protocol via pending_user_choices[], and abstract response contract for non-CC harnesses. 13 coupling points verified across runtime and Packs. Runtime probe confirms general-purpose subagents lack direct AskUserQuestion access. Implementation is out-of-scope; §8 lists 7 work items for a follow-up issue.
