The case against cost dashboards
Proof beats dashboards. Here's why we sign everything.
A dashboard is a claim. A signature is a fact.
Every paid operation produces a server-signed output (Ed25519). You - or your auditor - can verify it offline with no account. That's the anti-bypass root: there is no client-side licensing shortcut, and there is no “trust our number” step.
We report cost in tokens where the fact is tokens, and only translate to currency conservatively. We publish no savings percentage at all: the figure is measured on your own traffic, then signed. If we can't measure it, we don't claim it.
