//! Archive GRASP Services Integration Tests
//!
//! Tests that verify archive_grasp_services filtering behavior:
//! - Announcements with matching GRASP service domains are accepted
//! - Announcements with non-matching GRASP service domains are rejected
//! - Multiple configured services work correctly
//! - Case-insensitive domain matching
//!
//! # Test Strategy
//!
//! These tests verify the GRASP-05 archive mode with grasp_services filtering:
//! 1. Configure relay with specific GRASP service domains
//! 2. Send announcements with various clone URLs
//! 3. Verify announcements are accepted/rejected based on domain matching
//! 4. Verify repositories are created only for accepted announcements
//!
//! # Running Tests
//!
//! ```bash
//! # Run all archive grasp services tests
//! cargo test --test archive_grasp_services
//!
//! # Run specific test
//! cargo test --test archive_grasp_services test_archive_accepts_matching_grasp_service
//!
//! # With output for debugging
//! cargo test --test archive_grasp_services -- --nocapture
