# Graph workflow with a human-approval node (0.12.0 § D). A `kind=human` graph
# node pauses the traversal: the run returns a `blocked` result and persists a
# continuation, resumable with the reviewer's response. The human node's output
# routes the branch — approve → publish, reject → archive — via edge conditions.
# Non-human nodes use canned functions so the example runs end-to-end without a
# provider; retarget them before any real use.
