Verifiable Execution
What key components make up a signed step record in Catalyst?
A signed step record includes the step input, output, and a hash of the execution context. The payload is signed with a key bound to the agent identity, ensuring integrity and origin. This structure enables independent verification without external systems, but the signature does not validate the correctness of the agent's decision logic.

What is a verifiable execution record in Catalyst?
A signed, immutable sequence of agent steps enabling auditors to prove run integrity through independent replay. It does not validate decision correctness.
- Verifiable Execution
How does Catalyst ensure that step records are tamper-evident?
Catalyst uses a hash chain and digital signatures per step, so any alteration breaks the chain and becomes detectable through signature verification.

Can an auditor independently replay a Catalyst agent run to verify its outcome?
Auditors can replay runs using signed step records and initial state to verify output consistency, though non-determinism may limit exact reproduction.
