Application change at decommission

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})

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 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.
  • 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.
