"""Regression guard: shipped code must not reference old project names.

The FabledNetMon -> FabledScryer -> Roundtable -> Steward renames repeatedly left
stale names behind: package imports in the (then separate) plugins (e.g. `from
fabledscryer.models...`), silently breaking every non-host_agent plugin, and a
systemd unit still running `fablednetmon` as user `fablednetmon`. This test fails
loudly if a legacy name reappears in the shipped Python, templates, plugin
manifests or service units.
