+//! P6.7 Resource-pressure metrics + alerts (plan §14.9)
+//!
+//! Acceptance criteria:
+//! 1. All 7 metrics present on `:9090/metrics`
+//! 2. `miroir_memory_pressure` reports 2 when artificial allocation pushes RSS > 90% of limit
+//! 3. `MiroirNoLeader` fires after killing the leader without replacement within 1 min
+//! 4. `MiroirPeerDiscoveryGap` fires if headless Service misconfigured
+//!
+//! This test covers criteria 1 and 2. Criteria 3 and 4 require full Kubernetes
+//! integration testing and are covered by the chaos test scenarios (P9.4).
