Receipt linkage
Challenge references the exact receipt hash.
Provider A was not inside the submitted candidate commitment. It crosses the open boundary only if the signed quote was valid at decision time, eligible, and materially better.
An omission should be able to speak.
The public alpha uses a centralized deterministic resolver. A receipt is invalidated only after challenge validation and resolution.
No invalidation occurs until signed Provider A evidence is validated and resolved. The controls preview the deterministic cases from the committed sample bundle.
The packet satisfies this validation step.
The resolver has not accepted evidence yet.
The resolver has not accepted evidence yet.
The resolver has not accepted evidence yet.
Receipt status: provisional. It is valid only within the incomplete declared candidate set.
Provider B selected at $0.86 per gpu-hour.
Provider A at $0.75 per gpu-hour, 31 ms p95.
Quote hash: sha256:91e73ab2e30de9e003ea5799e5d5b76...
Challenge references the exact receipt hash.
Provider A is absent from the challenged candidate commitment.
The evidence quote is valid during the original decision window.
Provider A beats Provider B by more than the materiality threshold.
