Verifiable Execution
How does Catalyst attribute individual steps to different actors in a multi-agent or human-in-the-loop scenario?
Catalyst signs each step with an identity that reflects the acting component—such as a specific model version, a tool, or a human user—based on attested credentials. These identities become part of the verifiable record, linking actions to actors. The strength of attribution depends on the underlying identity system; Catalyst does not itself enforce strong authentication for human users.

- Verifiable Execution
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.
- Verifiable Execution
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.
