If it is not receipted in the Chronicle,
it did not happen.
The Chronicle Registry is an append-only, tamper-evident ledger.
It converts "trust us" into "verify this".
Chronicle Receipts are cryptographically bound records that prove who authorized an action, under which policy, and why it was allowed to occur.
What are Chronicle Receipts?
Chronicle Receipts form the append-only, tamper-evident authority ledger of the Cosmocrat OS. While logs track mutable system events, receipts are generated specifically for decisions. They bind policy, authority, context, and outcome into a single cryptographic proof.
This establishes the admissible "why" behind an action. By anchoring into Runtime Governance, receipts prove that the Gate System explicitly authorized the state transition.
It serves as the immutable truth for Decision Exhaust, providing the foundational evidence that Drift Guard relies on to detect divergence over time.
The Trust Gap
Logs tell stories. Receipts establish facts.

- Answers: "Why was it authorized?"
Receipts make AI actions non-repudiable — they cannot be denied, rewritten, or detached from authority.
The Anatomy of a Receipt
The Immutable "Why"
In standard systems, policies change, but old logs don't update. This creates "Policy Drift"—you can't prove why an action was allowed last month if the rules changed today.
Key Insight
Cosmocrat receipts stamp every action with the policy_hash active at that moment.
Result: No retroactive rule changes. No silent amendments. Perfect historical replayability.
