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 more
- 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. more
- 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. more
