Gate state is the one reading in the system with no judgement in it.

The function

Drawdown from the rolling peak, and nothing else enters.

Current equity is compared with the latest Equity Peak High; the resulting drawdown routes into one of seven gates from Growth through System Lock; the gate caps the maximum risk tier available to the throttle. Nothing else is an input. Not the quality of the current setup, not the week's expectancy tag, not the structural posture, not how the drawdown was incurred or how confident the operator feels about recovering it. Two numbers in, one authority level out — and the peak being rolling rather than fixed means accumulated gains are defended as they arrive rather than only the original deposit.

Why determinism is the point

A rule that can be reasoned with will be reasoned with.

The value here is not accuracy — a judgement-based capital posture could in principle be more accurate, since it could account for context the formula ignores. The value is that a computed state cannot be negotiated. There is no input the operator can adjust under pressure, no discretion to exercise about whether this particular drawdown really warrants compression, and therefore no conversation to have at the exact moment when the operator is least equipped to have it well. Determinism trades a little accuracy for the elimination of an entire failure mode, and the trade is deliberate.

What it deliberately ignores

The gate does not know why the drawdown happened, and must not.

A drawdown from a run of ordinary losses inside a healthy method and a drawdown from a broken method produce identical gate states. That looks like a defect and is a design choice: the cause is unknowable at the moment the decision is required, and every mechanism for supplying it is an opening for the more flattering explanation. The diagnostic layers exist to answer why, on their own timescale, and they answer it after the gate has already protected the capital. Protection precedes explanation because it has to — the explanation arrives too late to be a defence. The ordering also means the two layers never compete: by the time the diagnostics have a view, the capital decision they might have influenced has already been made and protected.

The precedence rule

Nothing tactical outranks it, and the list of things that do not is specific.

A favourable EV read cannot raise the tier ceiling. A constructive structural posture cannot. A strong Daily EV Status cannot. Volatility context cannot override a risk limit and diagnostics cannot cancel System Lock. Each of those is a genuine signal about something real, and none of them is about capital state — which is the only question the gate answers. Allowing a tactical reading to lift a capital constraint would mean the constraint binds exactly when evidence is weak and releases exactly when the operator is most confident, which inverts the protection it was built to provide. Each of those signals feeds the next authorisation through the evidence it contributes, on the following cycle, after review — never by lifting a ceiling in the moment.

• Two inputs — current equity and rolling Equity Peak High. Nothing else.
• The peak rolls, so accumulated gains are defended, not just the deposit.
• Cause is unknowable in the moment and every route to supplying it flatters.

The cost of the design

It will sometimes compress an account that did not need compressing.

This should be stated rather than glossed. An operator whose drawdown was ordinary variance inside an intact edge will have deployment reduced, will recover more slowly than they would have unconstrained, and will be able to demonstrate afterwards that the compression cost them. That is a real cost paid in every such instance, and it is the premium on the policy. The alternative — a gate that can be argued out of when the drawdown feels undeserved — is a gate that releases under precisely the conditions it exists for, because a drawdown always feels undeserved from inside it. The premium is paid on every ordinary drawdown and collects on the one that was not ordinary, which is the same shape as any insurance and should be judged the same way.

The key idea

This layer is trustworthy because it is incapable of being persuaded.

Most of CP3 earns trust through the quality of its reasoning. The gate earns it by having none. That is a different kind of reliability and the appropriate one for the layer that decides how much can be lost — it means the state on a bad Tuesday is the state the formula produced, identical to what it would have produced on a calm Sunday from the same two numbers, and the operator's condition at the moment of reading is not among the variables.
