 nor arti; among Mycelium's tests is a swarm simulated on its envelope).
 
+The benchmarks are ignored tests named `bench_*`: the document's (writes and sync
+messages, `document/bench.rs`), the remakes' replay (`remake/bench.rs`), and what

 The simulations send the wire encoding alone, as libp2p and Tor do; a simulated net
 can put messages into a transport's envelope instead (`SimNet::with_codec`), and every
 message kind is round-tripped through each codec (`wire::samples`).
