Two surfaces, one verdict — and only one of them is allowed to be obeyed.

The division

A verdict surface and an evidence surface, with different jobs.

The overlay carries one output: the regime, printed on the chart, alongside the management doctrine it implies. It is deliberately impoverished — a word and a level, with nothing to interpret. The pane carries the underlying geometry: the live volatility reading, its own moving average, and the threshold line the comparison is made against. Everything the overlay reduced to a word is visible there as a relationship between three lines. The pane can therefore be read for nuance the verdict cannot express, and it is the wrong surface to trade from.

Why they appear to disagree

The pane updates continuously and the verdict updates on a close.

The most common complaint about the pairing is that the pane looks strong while the overlay still reads Normal. This is the design working. The regime is computed on the authority timeframe, which means it changes only when that timeframe closes — while the pane's lines keep moving with every bar on the chart in front of you. Within an hour the reading can surge visibly and the verdict will not move. The overlay's stepped behaviour is the stability that a branch commitment requires, and the pane's responsiveness is what makes the step comprehensible instead of arbitrary.

The rule and its reason

Obey the surface that cannot be argued with.

The instruction is to trade only from the overlay's status. The reason is not that the pane is inaccurate — it is more informative, which is precisely the danger. A surface with continuous, richly readable output invites the operator to reach a conclusion slightly before the instrument does, and that conclusion always arrives in the direction the chart is already suggesting. The overlay's poverty is what makes it authoritative: there is nothing in a single word to interpret, and nothing to interpret is nothing to negotiate with.

What the pane is genuinely for

Grading the quality of a regime the verdict has already declared.

Consulting the pane has real value in a specific window — after the overlay has declared, when the question is how much confidence the declaration deserves. A reading well clear of the threshold and still rising describes a different trend day from one that has just barely crossed and is flattening. Both are Trend, both route to the same doctrine, and they warrant different selectivity about fresh entries. That is the pane's proper contribution: it grades within the verdict rather than competing with it.

• Well clear and rising — the doctrine has room, be normally selective.
• Barely across and flattening — same doctrine, treat fresh entries as fragile.
• The pane never changes the branch. It changes how eagerly you fill it.

The configuration obligation

Two scripts means two copies of every setting, matched by hand.

The pair shares its entire parameter set — the authority timeframe, the measurement lengths, and the threshold multiplier — and nothing links them. Entered differently, the pane stops being an explanation of the overlay and becomes a picture of a slightly different calculation, while continuing to look exactly like an explanation. This is the same maintenance obligation the session window carries across the trio, arriving here in a tighter form, because these two surfaces are supposed to be the same instrument seen twice.

The key idea

Separate the surface that decides from the surface that explains, and rank them once.

An instrument that both shows its reasoning and issues a verdict has to be explicit about which output is binding, or the reasoning will be used to overrule the verdict at exactly the moments the verdict was protecting against. The pairing here answers that by ranking the surfaces permanently rather than case by case. The explanation is available whenever it is wanted, and it never acquires authority by being more interesting to look at.
