//! Integration test — `tools/call` enforces the 60s timeout (MISS-4).
//!
//! Strategy: write a fake binary that sleeps significantly longer than the
//! cap. Use `tokio::test(start_paused = true)` so virtual time can be
//! advanced past the 60s deadline without the test thread blocking. The
//! real child is reaped by `kill_on_drop(true)` set in `spawn_and_collect`.
//!
//! Real wall-clock spent on this test: a couple of milliseconds — the
//! `sleep 90` child is spawned but killed before it finishes its first
//! second.
