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
