# Goal 2 — real detection (the central gap). A steady 4-node SWIM mesh; one
|
|
# node is genuinely killed mid-run (peer_kill: ticks stopped, in-flight and
|
|
# future deliveries dropped), so a survivor's probe TRULY times out — not an
|
|
# injected death. After `probe_timeout + suspicion_timeout`, every survivor must
|
|
# converge on the killed node being Dead (`peer_detected_dead_within`, the mirror
|
|
# of `dead_peer_resurrects_within`).
|
|
# Expected verdict: pass-now.
