"""Phase 3 — connection hierarchy (UI-REFRESH §4).

Three layers gate a connector for a session: account-connected → persona-default-enabled →
session-override. `effective(connector)` = connected AND (override if present, else persona default,
else inherit-on). These tests pin the stores, the resolver, and the two runtime gating points
(inbound delivery + the engine's connector tools).
