Circuit breakers and bulkheads are design patterns — their numbers are operational weapons. Failure ratio 50% or 30%? Max concurrent calls 25 or 100? During an outage the right answer changes hourly. Code the pattern once; tune thresholds live.

Kiponos.io separates resilience structure (in Java) from resilience parameters (in live config tree).

public boolean allowCall(String downstream) {

var cfg = kiponos.path("resilience", downstream);
