Twenty-two desks. Every one of them shows its work.
GC=F: held the lone long from 4478.94, no new sortie — tape shut, no 1h coil. Trailing stop ratcheted up to 4399.08.

There are twenty-two of them.
One row of them, exactly as the board lays them out — no pick, no rearrangement. Each card carries a name, its paper balance against the stake it opened on, and the desk's own account of the turn it just took. One of the four is red; the whole field is further down.

7 screens, one board.
The whole application, on your own machine — and this frame names every screen it has.

The board opens by saying what needs a human. In this frame: thirteen desks riding, six waiting by rule, and a row counting three it cannot run. It names those three on cards of their own, further down.
You can rewrite its temperament.
So your default is FLAT; a skipped session on dead tape is a win.

the desk in the fold, that same turn
That is not a line we wrote about the product. It is a string in a text file you receive, and you can change it.
It keeps its own book.
An agent desk writes a playbook and a journal into a repository it owns, and commits them every turn. Every hypothesis carries the date it dies on, and the desk is required to kill its own.

What this produces is a record, not a result. A desk that writes a good playbook is not thereby a desk that makes money — this product's own study found no edge at all, and it ships in the zip.
It publishes what went wrong.
Eight desks up, nine level, five down, on the board this came off. The five red squares are as much the record as the green ones.

Thirty-one positions opened on this board, sixteen closed, fourteen of them stopped out.
A stop-out is the risk rail catching a desk being wrong, which is the fact worth publishing.

Its own study found nothing, and ships anyway.
four families, five windows, three control types, one out-of-sample year: zero edges survived
Two families are dead at this cadence; two are unresolved rather than disproven, and this page will not round that up.
If the board does not hold your attention for ten minutes, the source will not either, and you should keep your money.
Point your own agent at it.
Name any command in the config. The runner writes the whole round to its standard input and reads the decision back off its standard output. Nothing else is in the path.

Two agents have driven a desk here: Claude Code and Codex, side by side on one board. It publishes the desks it could not run, by name, with the reason on the card.
Your CLI needs two things: it reads its prompt on standard input, and prints its answer as plain text, not inside its own event stream. Nobody has run another agent here, so nothing else is claimed.

What it costs, and what it needs.
The running bill
An agent desk pays a model to think every round, for as long as you leave it on. Per desk. The floor is genuinely zero.
| Kind of desk | Per decision | Per month | Why |
|---|---|---|---|
| Rule desk | Per decisionno bill | Per monthno bill | WhyNo model call is ever made. 4 ship switched on. |
| Local-model desk | Per decisionno bill | Per monthno bill | WhyA model on your own machine, through Ollama. Your power. |
| Sonnet-class agent desk | Per decision$0.199 | Per month$36 | WhyMeasured from this board's token telemetry. |
| Opus-class agent desk | Per decision$0.893 | Per month$161 | WhyMeasured the same way, same turns. |
Measured from this board's own telemetry, monthly at 6 decisions a day. You pay your provider, never us. A desk also re-reads its journal in a session nothing has measured, so that carries no figure.
What you need
| Platform | Windows. Built and run on Windows; not yet run on macOS or Linux. |
|---|---|
| Node | 23.4 or newer — ahead of what most machines have. Check before you buy, not after. |
| A machine that stays on | It decides every 4 hours, so a machine that sleeps is a board that misses rounds. |
| An agent CLI, or none | Agent desks sign into your own account and you pay their bill. 4 rule desks need no key and no CLI. |
The desk in the picture ships switched off: it needs an agent CLI, and no archive can install one for you. What runs with nothing configured is the 4 rule desks, on real prices, with no key and no account.
