// #92183 — two basic-auth (cookie-flow) gateways registered in the v2
// connections registry must not share one cookie jar. Chromium cookie jars
// ignore the port, so two gateways on the same VPN host (different ports)
// evict each other's `hermes_session*` cookies when they ride the single
// shared `persist:hermes-remote-oauth` partition — and, worse, gateway A's
// cookie is silently PRESENTED to gateway B on every request. The resolver
// under test keys the jar on the registry connection's identity instead.
