Verified on Two Vendors: When the Verdict Flips on Physics Alone
Same code, same operator, same Svetlichny witness — run on IonQ Forte-1 instead of Rigetti Cepheus, the verdict flips to a decisive PASS at |Sv| = 5.366. The only field that changed was the device.

We spent real Braket credits and got a REJECT, and we're publishing it. The verifier discriminates on physics, not money: below about 70.7% hardware fidelity, a Bell violation is impossible, so it honestly says no.

We ran CHSH — a completely different Bell inequality — on the same Rigetti hardware, and the same verifier checked it with zero code changes. That's the difference between a protocol and a demo.

What's actually inside a Proof-of-Coherence block — from the quantum-derived signature to the Merkle-anchored measurement record you can verify yourself.
