Escalates one rung when the same code fires N times inside a window, and decays one rung after a
clean interval. Never a fixed retry loop: the alarm chain already learned that the hard way,
where a failing step that re-armed at +1 ms spun the object forever and starved every gated
request, and the fix was min(30 s, 1 s x failures).
Circuit breaker with decay.
