A successful turn returning exactly NO_REPLY (or another exact silence
marker) leaked the literal control token when a second message was queued
before the first turn finished. The queued-follow-up recovery branch sends
the first final_response directly through adapter.send() and predates the
silence filter added to the normal completed-turn path.
Use the finalized task result for that recovery delivery rather than the raw
result_holder copy, then apply the existing
is_intentional_silence_agent_result() predicate before sending. This keeps
the established contract: only successful exact-marker turns suppress;
substantive prose and failed results still send; stream-confirmed responses
still skip the resend; and persisted history is untouched. Using finalized
output also preserves normal empty/failure normalization on this direct path.
Integration regressions run the real Slack _run_agent queued-follow-up flow:
one proves NO_REPLY never reaches the adapter while the second turn still
runs; another proves an empty failed first turn sends its normalized error
before the queued follow-up. Existing filter tests cover every supported
marker, prose mentions, and failed-result semantics.
