// A healthy machine reports a single `start: started` after launch and stays
// quiet. A boot-looping container (e.g. Node throws on import → Fly restarts
// → throws → restarts) emits a steady cadence of `launch: pending` →
// `start: started` → `exit: stopped` triples roughly every 10s.

// the Docker driver passes the daemon's own action through as `[container] die`.
// Matching only Fly's wording meant a restart-looping Docker
