tests/_fake_opencode.py implements the two commands MAM calls (debug paths,
session delete) as measured on 2.0.32; unit tests never run a real opencode
(it would migrate the test database). test_real_opencode_2x_contract runs a
real 2.x opencode, when installed, in a home and tmp dir of its own with
--standalone.
