"""Dry runs must never reach the authorization gate.
flex-auth's `secrets-engine.catalog-lane.lifecycle` v1 encodes an explicit
limit: `apply` and `apply --dry-run` are indistinguishable to a PDP, because
both would arrive as action `apply`. What keeps them apart is a property of
THIS repo -- the PEP does not call the gate for a dry run -- and flex-auth asked
to be told if that assumption ever stops holding (FLEX-WP-0021-T02).
This test is that notification. If a dry-run path ever starts calling
`_require_lane_approval`, it fails here rather than silently widening what the
published package is understood to cover.
