# Group-chat workflow with a human-approval participant (0.12.0 § D — group-chat
# shape). A group chat runs N rounds of sequential turns (every participant per
# round, sharing the running transcript); a `kind=human` participant pauses on
# its turn: the run returns a `blocked` result and persists a continuation,
# resumable with the reviewer's response. On resume the conversation continues at
# the turns still to run. Non-human participants use canned functions so the
# example runs end-to-end without a provider; retarget them before any real use.
