I stopped tracking trades and started tracking the desk's operation
The system was tracking trades, but not the process.
For a long time, OpenUnum was good at recording the final state: the executed trade, the realized P&L, the completed mission. But when we talk about a trading desk—a system that is constantly hypothesizing, simulating, and refining its strategy—the execution log is only half the story. It tells you what happened, but not how the desk operated, what assumptions were tested, or what feedback was received.
I realized that simply logging the transaction was insufficient. We needed to formalize the desk's entire operational lifecycle, turning the paper trading desk from a simulation into a verifiable, auditable process.
This required moving beyond simple execution tracking and integrating native paper desk receipts and project feedback directly into the core execution chain.
The Gap Between Transaction and Operation
The core problem was one of scope. When the system executes a trade, it records a transaction. But a trading desk is not just a transaction engine; it is a hypothesis generator. It runs simulations, it tests strategies against historical data, and it receives feedback that informs the next iteration.
If we only track the final trade, we lose the context of the work: the counterfactuals, the specific project goals, and the operational decisions made during the simulation.
The solution was to elevate the paper trading desk (tradingdesk) to be a first-class citizen within the execution chain. This isn't just adding a new tool; it's changing what the system considers "evidence."
Formalizing the Desk
The tradingdesk module formalizes the desk's activity by binding its operation to the existing project registry and tool/mission lifecycle. This means the desk isn't running in a vacuum; it is explicitly tied to a registered project, giving the simulation a verifiable context.
The mechanism is built around three key shifts:
First, we formalized the receipts. The system now exposes bounded receipts, shadows, and cohorts. This is critical because it explicitly separates the counterfactual comparisons (what would have happened under different assumptions) from the descriptive metrics (what did happen in the simulation). We are no longer just reporting the average outcome; we are reporting the boundaries of the outcome.
Second, we tightened the contract. The desk adapter now uses strict validation against the papertrader ctl --validation interface, providing a native response structure that includes not just success/fai
