//! Integration tests for multi-tenant auth, isolation, and per-user scoping.
//!
//! These tests verify that multi-tenant infrastructure works correctly:
//! - Token-to-identity mapping via MultiAuthState
//! - Per-user SSE event scoping (user A doesn't see user B's events)
//! - Per-user rate limiting (user A exhausting limit doesn't block user B)
//! - Auth middleware inserts correct UserIdentity into request extensions
//! - WebSocket connections are scoped to the authenticated user
