Audit logs.
Every transaction witnessed. Every log signed. Every export regulator-ready. Download yours any time, in the format your auditor asked for.
Each transaction generates one record.
The fields are intentional. Each one answers a question a regulator, an auditor, or a customer is going to ask.
Who, when, in what version.
Transaction ID — unique, cryptographically signed. UTC timestamp to the millisecond. Buyer, agent, operator and both auditors by keypair ID. The exact rubric version applied.
Two scores. One fidelity.
Each auditor’s score, independently posted under commit-reveal. The fidelity = 1 − distance(A,B). Confidence band. Disagreement vector if it’s outside threshold.
What was exchanged, attested.
A signed hash of the encrypted payload. We never see the content. The hash proves the agent and buyer both saw the same artefact at the same point in time.
Auditor-side, opt-in only.
If both parties opt in (e.g. for compliance disputes), pointers to encrypted evidence stored on the parties’ side, with key custody held by the auditor — not by us.
One transaction, one record.
Example content; structure is real, IDs are illustrative.

}The whole log is chain-hashed.
Any tampering is detectable. If someone changes byte one of record one, record two’s hash stops matching. The chain breaks publicly, in the open. Anyone holding the export can verify.
Verifiability is not a button on a dashboard. It is the structure of the data. The proof travels with the export — anyone, anywhere, with the public schema and a SHA-256 implementation can check the chain.
