A certified decision is not just an output. It is an output backed by a Certified Execution Record that proves the conditions under which it was produced.
The decision is bound to its inputs, parameters, and execution context inside a CER. The CER is sealed by a SHA-256 certificate hash and countersigned by an independent attestation node.
An output without context is just a string. A certified decision carries its own evidence: what was asked, what was known, what parameters applied, and what the system actually returned.
If any protected field is modified after sealing, the certificate hash no longer matches and verification fails. The decision is either intact or it is not.
Context signals capture the conditions of execution. When context is included in the CER, it is protected by the same cryptographic seal as the inputs and outputs.
Approvals, denials, risk scoring, content moderation, automated reviews, regulated workflows, and any AI decision that may later need to be defended.
Your system makes a decision through an AI call. NexArt seals the call into a CER. An attestation node countersigns it. Anyone can later verify the decision's integrity at verify.nexart.io.
