+//! GRASP-02 Phase 4: Dynamic Subscription Integration Tests
+//!
+//! Tests verify dynamic subscription management:
+//! - New announcement triggers Layer 2 subscription
+//! - New PR/Issue triggers Layer 3 subscription
+//! - Subscription count tracking per connection
+//! - Consolidation at filter count > 150
+//! - No duplicate subscriptions
+//!
+//! # Running Tests

+//! ```bash
+//! cargo test --test proactive_sync_dynamic
+//! cargo test --test proactive_sync_dynamic -- --nocapture
