#![cfg(feature = "test-network")]
//! Minimal repro harness for connection-cap enforcement.
//!
//! This test spins up a tiny network (2 gateways + 6 peers) with a low max-connections
//! setting (min=5, max=6) and waits for connectivity. It then inspects diagnostics to
//! ensure no peer reports more than `max` connections. This is intended to quickly catch
//! admission/cap bypass regressions without running the full soak.

use freenet_test_network::{BuildProfile, FreenetBinary, NetworkBuilder};

#[test_log::test(tokio::test(flavor = "current_thread", start_paused = true))]
