Dependent autocomplete scope changes: incompatible selected child survives a parent change · case 05

The child completion transition produces an incorrect observable state.

Case contract

Changing the parent picker invalidates child suggestions, child query epoch and incompatible child value. Draft may be preserved for a new scoped search. Child labels are never used as parent identifiers, and clearing a parent disables dependent search. Compatible values survive explicit scope membership checks.

Why this case matters

Autocomplete couples draft text, suggestion identity and asynchronous presentation; this bounded lifecycle model isolates one observable interaction defect.
