The zone ladder
Five states, and only the ends carry an instruction a static branch can execute.
The volatility zone classifies the instrument's current reading against its own percentile history: very low, low, normal, high, extreme. For a trend operator every band carries a coefficient implication. For a static operator the middle three carry nothing actionable — a fixed break-even and a fixed target behave the same way across ordinary variation, which is what makes them a static architecture in the first place. The two ends are different. Very low argues that the target may simply not be reachable in the time the plan allows; extreme argues that ordinary noise now spans the distance between entry and stop.
The middle of the ladder is where a static architecture is designed to operate and needs no adjustment. The instruction lives at the ends, and at both ends it is the same instruction.
