Verifiable Execution
How does Catalyst bind a verifiable record to the identity of the user who requested the execution?
The signed execution record typically includes the authenticated user’s identity as part of the initial invocation metadata, which is signed alongside the first step. This binds the whole run to the requester. However, identity binding assumes that authentication at the point of invocation was correct and that the user’s credentials haven’t been compromised; the record doesn’t independently verify the user’s identity.

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.

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.
