Test Sub-Pattern

Prerequisite Check

Before writing tests, verify the pattern has:

• pattern<Input, Output>() (not single-type pattern<State>())
• Actions typed as Stream<T> in Output interface
• Bound handlers returned from the pattern

If missing, fix the pattern first - tests can't call .send() without proper Output types.
