Save and load
=============

Seam: A saved shared object round-trips; a saved program runs its named goal.
The public save uses main=M.main for a program and no main for a module.

Run ./run after make stage, or run unit_boundary.py from tests/.
The run script selects the staged Python and the session backend.
expected.out records stdout; stderr is shown on failure by the test.
The driver comments explain the individual probes and their order.
The corpus README.md lists the backends and the oracle for this driver.
