Expected behavior

test pass

Audited main for other instances of the same pattern (driver-only version check gating a binding function). Found two more:

_module.pyx:461-465 — Kernel._get_arguments_info()

Only checks cy_driver_version() < (12, 4, 0), but calls cydriver.cuKernelGetParamInfo() at line 473. Missing cy_binding_version() check. Exposed via Kernel.num_arguments and Kernel.arguments_info.

tests/graph/test_graph_definition.py:51-57 — _driver_has_node_get_params()

Test helper only checks driver_version() >= (13, 2, 0) — same pattern as the source-level bug. Used at lines 518/529/540/551 to decide the expected reconstructed_class for conditional node parametrize specs.
