The drawdown distribution was generated with the gate ladder switched on.

What is baked in

Every path in the distribution obeyed the ladder on the way down.

The simulated drawdown distribution is produced by paths that evaluate their drawdown state after every completed cycle and re-cap deployment accordingly. A path sliding past the first threshold is capped before its next cycle; past the second, compressed further; and so on to the terminal boundary. The bands are therefore not a neutral description of adverse sequences. They are a description of adverse sequences met with governance, which is a materially narrower and shallower set of outcomes than the same sequences met with fixed sizing. The compression is inside the numbers before the operator ever looks at them.

What a breach actually claims

The accusation is specific and it is not about the market.

Because braking is assumed, a live drawdown outside the adverse bands cannot be explained by the market having been hostile — hostile sequences are exactly what the distribution sampled, with the brakes on. The breach says something narrower: the damage exceeded what disciplined braking produces under this system's own assumptions. That points the review in a direction, and it is not toward conditions. It is toward whether the braking happened as modelled, whether deployment respected the caps, whether open exposure compressed fresh trades, and whether the sizing that fed the gates was the sizing the model assumed.

The three explanations that survive

Over-risk, execution weakness, or a system weaker than modelled.

The page's own reading names the surviving candidates, and the list is short because the braking assumption eliminates the comfortable ones. Over-risk means deployment exceeded what the gate authorised, whether through override use or sizing error. Execution weakness means the trades themselves underperformed their modelled behaviour — worse fills, worse adherence, stops handled differently than assumed. A structurally weaker system than modelled means the assumptions themselves are stale and the ruler is measuring something the account no longer is. Each has a different investigation attached, and none of them is bad luck, because bad luck is what the distribution already contains.

The corollary for recoveries

Slow climbs are also inside the bands, and they are not dysfunction.

The braking assumption cuts in the other direction too. Governed paths recover slowly from deep drawdowns because the deeper gates cap the very tiers that would recover fastest, and the distribution's recovery profile inherits that. An operator climbing out of a deep drawdown at what feels like an unreasonable pace is usually inside the modelled behaviour, not below it. This matters because slow recovery is the condition that most reliably produces the argument for a temporary override — and the bands say plainly that the slowness was priced in, deliberately, as the cost of the shallower bottom that preceded it.

The maintenance dependency

If the live gate configuration changes, the bands are stale immediately.

One practical consequence deserves stating. Because the ladder is inside the distribution, any change to the ladder — thresholds, tier caps, pool rows — obsoletes the drawdown bands the moment it is approved, more urgently than it obsoletes the equity bands. The distribution is conditional on a governance configuration, and comparing live drawdown to bands generated under a different one produces a difference that reads as performance and is actually specification. This is the event trigger in the refresh standard doing real work, and drawdown is the distribution where ignoring it goes wrong fastest.

• The bands are conditional on the ladder, not merely informed by it.
• A breach interrogates compliance and sizing before it interrogates conditions.
• A gate-configuration change requires a benchmark regeneration before the next drawdown comparison.

The key idea

Knowing what a distribution assumed is most of knowing what it means.

The drawdown bands look like a fact about markets and are a fact about a system operating in markets under a specific set of brakes. Read that way, they become far more useful: the ordinary territory is genuinely ordinary for a governed account, the slow climbs are the purchase price of the shallow bottoms, and a breach stops being a story about severity and becomes a short list of things to check about the account. The bands never needed to be more severe to be honest. They needed the brakes to be visible.
