Fails when Sigra references leak outside the allowed integration namespace.
The fence scans the repo-owned lib/scrypath/, scrypath_ops/lib/, and
scrypath_ops/test/ trees. Only the Sigra integration namespace and the
bounded OPSUI LiveView surfaces that consume that integration are allowed to
contain Sigra. references inside scrypath_ops.
