"""A cloud-hosted workflow's timer belongs to the server, not to this machine.
The failure these guard against is a double run: if the laptop is awake when a
cloud-hosted slot comes due, both the laptop and the server fire it, and the
user gets two of everything. Ownership is expressed once, on
Workflow.execution_target, and every reader of the schedule must honour it.
Run:
cd backend && .venv/bin/python -m pytest tests/test_schedule_execution_target.py -v
