FINALBOSS

How it works

One rule.

No receipt. No run.

An AI action can only run if FinalBoss has already signed a receipt allowing it. Not a log written afterward. A key issued before.

01 · Where it sits

Underneath the AI. Not beside it.

FinalBoss runs at the operating system, on your hardware. The AI never holds the key, so it cannot talk its way past the gate.

1 Who asked. The agent's identity, not its word for it.

2 What exactly. The action and its target, down to the account.

3 The authority. The permission on file that allows it, or none.

4 The decision. Yes or no, written before anything moves.

5 A link to the last receipt. Delete one and the chain breaks.

6 Two signatures. Classic plus post-quantum. Anyone can check them offline.

Before you go live

BEAST finds what would have gotten through.

BEAST runs your agents against thousands of off-limits actions before production and shows what was blocked, and what was only logged.
