The manifest is the only contract a consumer has, since no source package
is shared between node repositories, and dora validate checks a dataflow
against it without running the node — so CI needs no robot.
request and response are deliberately untyped. They carry request_id, and
dora defines that as the marker for a pattern-correlated port where
several Arrow schemas legitimately flow, one per service; the runtime
skips type checks on those messages, so annotating them would claim a
contract neither side keeps.
examples/ carries its own manifest because dora resolves a node's
manifest by walking up from its path, and a manifest applies only when
<manifest dir>/<entrypoint> names the same file as the dataflow's path.
Without it the example caller would be matched against the arm node's
manifest and strict validation would fail on the entrypoint mismatch.
