"""Regression: per-profile PairingStore creation in _start_secondary_profile_adapters.

``gateway/run.py`` referenced ``PairingStore`` at method scope in
``_start_secondary_profile_adapters`` while the class's only import was
method-local inside ``__init__`` — a ``NameError`` at runtime, silently
swallowed by the enclosing ``try/except``, so multiplexing gateways never
created per-profile pairing stores and authz pairing checks for secondary
profiles fell through to the global whitelist.

These tests drive the REAL method (bound onto a bare runner) with the
profile-enumeration and adapter-startup collaborators stubbed, and assert
the per-profile stores actually materialize.
