Breach Can't Flow Uphill: How Separate Trees Contain a Blow-Up

A copier is a multiplier. It multiplies good decisions, and it multiplies the bad one that ends an account. The question every farm has to answer before it turns the copier on is simple to state: if one account breaches, what else breaches with it?

The answer we want is "nothing that didn't deserve to." The way to get that answer by construction rather than by hope is to make sure a breach can only travel downhill — from the account that caused it to the accounts following it — and never up, into the accounts that fund the farm.

The mixed tree, and why it depends on luck

Picture one copy tree: a leader and a set of followers, some evaluations and some funded. On an ordinary day it works. Now consider the day the leader — say it is an evaluation being pushed toward its target — takes the losing sequence that breaches it. Every follower took the same trades. If the followers include funded seats, the farm's cashflow just took an evaluation's risk.

You can argue the leader should have been the funded account. Then the evaluations follow a rhythm that isn't aimed at their target, and the farm's containment now depends on the funded seat never having its own bad day — which it will. Whichever way you arrange one tree, the safety of the farm depends on *which account happens to be leading*. That is a bet, not a design.

Two trees, and what "by construction" means

Split the farm into an evaluation tree and a funded tree, as evals sync with evals, fundeds with fundeds describes, and the question changes shape:

- An evaluation that breaches takes down, at most, the other evaluations following the same leader — accounts whose job was to attempt a pass and whose fee was the known cost of the attempt. - A funded seat that breaches takes down, at most, other funded seats — and the funded tree is traded to a safer objective in the first place, so that day is rarer by design. - Neither event can cross into the other tree, because there is no path between them.

Nothing about that depends on who was leading. The containment is a property of the wiring.

It is stronger than the old idea, not weaker

An earlier version of this principle — "the funded account leads, so a breach cannot flow uphill to it" — was a special case that only held while there was one funded account. With two trees the same guarantee holds for every funded account at once, and the evaluations are free to be traded as evaluations.

What the trees do not protect you from

The one thing no wiring can contain is correlation *within* a tree. Firms ban hedging across your own accounts, so every seat in a tree is the same directional bet at once; a bad day is a bad day across the whole tree. That is sized for, not wired around — trailing drawdown across many accounts is where we take it apart.
