Auditor evidence pack

Debt item at ratify

Engineering · Technical Debt · line EN8C · Debt Doctrine Position. 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. 5 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})

Authority relied on

Who was allowed to do this, up to what value, in which jurisdictions

EN8-AUTH-A1ActiveTechnical Debt Orchestrator

Any unit on a technical debt line where every intake check passed, the policy in force is current, and the value sits inside the cap below.

Anything the agent grant refuses, plus any override of an agent outcome. An override must state what the agent concluded and why it is being set aside.

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.
