The old backtest loading screen quietly lied to you — miming a machine grinding through the math in the second you pressed Run, when the real work was long finished. So we replaced the performance with the truth.
Press Run now and you watch a vault open. A reel spins and settles on a real card number — the last digits of the very card you're about to read — and then the four gates light in turn: Walk-Forward, Out-of-Sample, Robustness, Monte-Carlo. It locks on the champion. About eighteen seconds, and every beat of it is honest — every card in the vault has already passed all four gates before you ever pressed the button. What you're watching isn't a machine thinking. It's a card being drawn.
We could have left the old spinner spinning. It looked busy, and busy looks like value — but a lab that shades the truth in its smallest corner has no standing to ask your trust with the big ones. If the waiting is going to tell you a story, the story has to be real.
And the card you draw is still just that — a faithful account of how a strategy behaved on data already written. Watching it get pulled from the vault makes that record no more of a promise about tomorrow than it ever was.
