Scenario
Press start once the baseline is calibrated. The chaos container then shapes the server's egress: delay + jitter, then 10% loss, then a full cut, then recovery. Watch the compose terminal for the ground-truth phase markers.
Link health
Red line: risk (dashed: warn 0.25, trigger 0.40). Blue line: RTT. W / T / C / R: warning, trigger, cut, restored. Top lane: what the chaos container did (ground truth; it reaches the page only while the link is up, so the cut appears after reconnect). Second lane: what the client believed.
