# Concurrent workflow with a human-approval participant (0.12.0 § D — concurrent
# shape). A concurrent fan-out runs every participant against the same input
# snapshot in parallel. When a `kind=human` participant is present the run is
# "drain-then-block": the non-human siblings run to completion (they are
# independent of the human gate), their results are captured, and the run blocks
# on the human. On resume the human response is merged with the already-complete
# sibling results — siblings are never re-run. At most ONE human participant is
# allowed per concurrent fan-out (E_ORCHESTRATION_MULTI_HUMAN_UNSUPPORTED).
# Non-human participants use canned functions so the example runs end-to-end
# without a provider; retarget them before any real use.
