"""A research package that knows nothing about Fluksio, except where it says so.

Each node is a thin wrapper over a plain function: `prepare` stores what
`make_rows` made, `fit` yields what `train_curve` computed, `evaluate` reports
what `score` worked out. That split is the point — the arithmetic stays plain
Python, so `python -m myresearch.pipeline` runs it with no engine anywhere,
while the wrappers own the artifact storage. `fluksio sync examples/myresearch`
is what turns the wrappers into a flow.
