- Fix resilient_background rename: ResponsesServerOptions no longer
accepts durable_background (renamed to resilient_background in b8).
The old name caused a silent TypeError that disabled crash recovery
in hosted environments.
- Add steerable_conversations parameter to ResponsesHostServer.__init__.
When True, concurrent turns on the same conversation chain are queued
rather than rejected with 409 conversation_locked. The flag is threaded
into ResponsesServerOptions and composed with resilient_background in
the auto-enable path for hosted environments.
- Fix streaming cancellation terminal: both _handle_inner_agent and
_handle_inner_workflow now emit response.completed before returning
when cancellation_signal fires. Per spec §10, the handler must emit
a terminal event; the framework overrides completed → cancelled when
context.client_cancelled=True (real client cancel), and leaves it as
completed for steering pressure (client_cancelled=False). Previously
returning without a terminal caused the framework to force failed,
which broke the steered-turn chain.
- Add comment in _handle_inner_workflow explaining the relationship
between previous_response_id and conversation_chain_id for steerable
turns (they resolve to the same key, so the existing restore logic
is already correct).
- Update tests: rename resilient_background tests, update cancellation
test to assert response.completed is emitted, add three new tests
for steerable_conversations threading and precedence rules.
