+//! GRASP-01 Repository Creation Tests
+//!
+//! Tests that verify bare Git repositories are created when repository announcements
+//! are accepted by the relay.
+//!
+//! ## Test Coverage
+//!
+//! - Repository creation on valid announcement
+//! - Idempotent creation (no error if repo already exists)
+//! - Proper directory structure (<npub>/<identifier>.git)
+//! - Bare repository validation (has HEAD, config, objects, refs)
+//!
+//! ## Running Tests
+//!
+//! ```bash
+//! cd grasp-audit && nix develop -c bash test-ngit-relay.sh --mode test
+//! ```
