Value data model
================

Seam: Converted scalars and containers obey the Python data model.
A held Term stays unchanged; type annotations are checked by unification.

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.
