What it establishes
Hexarch treats policy change as a first-class event. The record is append-only, tamper-evident, and tied to authorship.
PROOF
When Policy Changes, Decisions Change
Policies are not static. This proof shows how changes are recorded, chained, and made historically traceable—so a decision can be anchored to the policy state that produced it.
Why it matters
During incidents and audits, “what was true at the time” is the whole question. This makes policy causality inspectable, not assumed.
What to look for
- Change diff + signer + timestamp.
- A stable chain link that can be verified later.
- Selective disclosure: prove facts without exposing everything.
