Native run 37190464303 (first merge-time kill): git merge was held writing
hermes_constants.py with index.lock held and killed there. Every next
launch then died with ModuleNotFoundError: the launcher
(hermes_cli/_launchers.py::_launcher_script) imports hermes_constants from
the checkout before import hermes_bootstrap, whose
restore_interrupted_pull is the repair, so the repair never runs and even
hermes update fails. The bricked install then failed every later cell.
mid_git now runs last, and its recovery assertions sit under a
known_failure keyed on exactly that traceback (owner upd-txn: strict
acceptance fails on it). The hold precondition (index.lock left by the
kill) is asserted outside the gate.
