Every action leaves a signed record: what the agent intended, the verdict it received, and a receipt anyone can verify. From intent to proof, nothing is left to trust.
The ledger is chained, append-only, and complete. There is no gap to hide in, and no way to quietly change the past.
Each record is chained to the one before it. Alter a single entry and the whole chain breaks.
Records are written a single time and never changed. The ledger only ever grows.
Every authorisation decision is sealed to the vault, so there is no action without a receipt.
Every record is signed, verifiable on your own, and shareable one decision at a time. Nothing to take on faith.
Each decision is signed with ECDSA P-256, so who wrote it and whether it changed are both provable.
Verify any record on your own, with the public key alone. No call back to Xybern required.
Disclose signed proof of a single decision without exposing the rest of your history.
When a regulator or an auditor asks, the answer is a signed pack, not a scramble. Scope it to a period, an agent, or a single decision.
Evidence of human oversight and risk controls, with a record for every high-risk action.
A signed, timestamped trail for every automated action taken within your limits.
Prove that every touch of protected data was authorised, with the receipt to show it.
Produce a signed proof pack for any period, agent, or decision, ready to hand over.
An immutable ledger, audit exports, forensic reporting, and proof of authorisation, the pieces that turn decisions into evidence.
Put one workflow behind the Authorisation Layer and watch each decision seal to the vault, signed, chained, and ready for audit.
Every action leaves a signed record: what the agent intended, the verdict it received, and a receipt anyone can verify. From intent to proof, nothing is left to trust.
A record captures the intent, the matched policy and verdict, and a signed, hash-chained receipt. It links to the entry before it, so the whole ledger is tamper-evident.
The record is written once, at decision time, and never altered. Any later change breaks the chain, which is exactly how tampering is detected.
Verify a record on your own with the public key, disclose a single decision without exposing the rest, or export a scoped pack for audit.
