Auditor evidence pack

Pipeline run at model schema

Information Technology · Data & Integration Platform · line IT8B · Data Product Release. This pack names every action taken on this unit, who or what took it, the authority that permitted it, and the model, prompt and policy versions in force at that moment.

Chain verified

Every record links to the one before it and hashes to its stored value. 2 records were re-hashed on this page load, in order, starting from the genesis value. Nothing was read from a cached verdict.

hash = sha256(prevHash + "|" + JSON{seq, unitRef, actor, action, outcome, occurredAt})

What this pack proves, and what it does not

Read this before you rely on it

It does prove
  • Every action carries a named actor, an actor kind, and a timestamp.
  • Every action names the authority grant that permitted it and the cap that grant carries.
  • Every action stamps the model, prompt, policy and tool versions in force at that moment.
  • Corrections are additive. A later record supersedes an earlier one and says why; the earlier record is never edited or deleted.
  • The chain is re-hashed live on this page, so a single altered field is detected immediately.
It does not prove
  • It is not tamper-proof against an attacker with write access to the store, who could rewrite the whole chain from genesis. Making that impossible requires publishing chain tips to a store this application cannot write to. That anchor is not built, and this page does not claim it.
  • The evidence in this demonstration is modeled from a simulated estate, not captured from production systems.
  • Identity here is the actor name recorded on the action. Cryptographic agent identity and signed attestation are a separate piece of work.
